1. Suppose that society decided to cut down ingestion and increase investing. a. How would this alteration affect economic growing? * Doing so will decidedly impact the hard currency flow within the community doing it difficult for companies to derive net income. Monetary values will certainly be lowered down. and stocks might be put to blow since there are so much available. B. What groups in society would profit from this alteration? What groups might be hurt? * Groups of people who are evidently into salvaging but at the same clip hazard takers would most probably be happy on increasing their investing. These are the type of people who are ever economical and will ever hold 2nd ideas on geting things. Those with concerns that is in the goods-consumption industry. which is the chief beginning of their income. would non be so happy with this sort of incident. 2. Societies choose what portion of their resources to give to ingestion and what portion to give to investing. We will write a custom essay sample on Basic Macroeconomics Essay Sample or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Some of these determinations involve private disbursement ; others involve authorities disbursement. a. Describe some signifiers of private disbursement that represent ingestion and some signifiers that represent investing. The national income histories include tuition as portion of consumer disbursement. In your sentiment. are the resources you devote to your instruction a signifier of ingestion or a signifier of investing? * Private disbursement includes geting those demands. eg. Food. vesture. medical specialty. Investing for me ever includes something that would do your disbursement much worthwhile and you would derive something out of it. It could be a wellness insurance. a house or some portions in a little company. * Education for me can be both a signifier of ingestion and a signifier of investing. Consumption because you use money to pay for your tuition. and it reduces your hard currency on manus. Investing because with all that disbursement. you gain something that will assist you out in increasing your cyberspace worth and that is called cognition. B. Describe some signifiers of authorities disbursement that represent ingestion and some signifiers that represent investing. In your sentiment. should we see authorities disbursement on wellness plans as a signifier of ingestion or investing? Would you separate between wellness plans for the immature and wellness plans for the aged? * When a authorities acquires goods and services for current usage to straight fulfill person or corporate demands of the members of the community. it is called ingestion. But when they get such intended to make future benefits. such as substructure investing or research disbursement. it is investing. * Like I mentioned on instruction. every bit long as you use money to pay for things. I consider it ingestion but in respects to wellness plans. acquisition of high engineering equipment for wellness grounds. so it would be more likely an investing. Prolonging someone’s life is decidedly a signifier of investing. * Government disbursement on wellness plans is an investing on human capital. This is more apparent for passing on wellness plans for the immature instead than the aged. 3. Most states. including the United States. import significant sums of goods and services from other states. Yet the chapter says that a state can bask a high criterion of populating merely if it can bring forth a big measure of goods and services itself. Can you accommodate these two facts? * Importing will give you the option to portion your forte to other states therefore doing your mark market bigger and would most likely do your net income bigger every bit good. Gaining more net income will do your criterion of life higher with importation. 5. Suppose that an car company owned wholly by German citizens opens a new mill in South Carolina.a. What kind of foreign investing would this represent? * It represents a Foreign Direct Investment. B. What would be the consequence of this investing on US GDP? Would the consequence on US GNP be larger or smaller? * The investing increases US GDP because it increases production in the US. The consequence on US GNP would be smaller because the proprietors would acquire paid a return on their investing that would be portion of German GNP instead than US GNP. 8. International informations show a positive correlativity between income per individual and the wellness of the population.a. Explain how higher income might do better wellness results. * Persons with higher incomes have better entree to clean H2O. medical attention. and good nutrition. B. Explain how better wellness results might do higher income. * Healthier persons are likely to be more productive. c. How might the comparative importance of your two hypothesis be relevant for public policy? * Understanding the way of causing will assist policymakers place proper accent on the plans that will accomplish both greater wellness and higher incomes.

How to control email (and free yourself)

How to control email (and free yourself) How to control email (and free yourself) If there’s one area that unites most professionals, it’s the struggle with email. Whether it’s how to manage the daily deluge of messages in our inboxes, how to respond to them or how to write them so they don’t lead to misunderstandings, finding ways to control email (and not let it control us) is a challenge we all face. The trouble is that email is everywhere. We send and receive more than 205bn emails a day [PDF], and when we open our laptops, email is usually the first thing we look at. Many of us will even check our inboxes immediately after our alarm wakes us in the morning. At biologys mercy Our biology doesn’t help: we’re wired to search. That brief frisson of pleasure you feel when you realise someone’s emailed you is actually a small rush of the hormone dopamine. Unfortunately, it usually is very brief indeed, and followed by a sinking feeling as you realise it’s just another problem to deal with. Opening yourself up to this kind of stress while you’re half-asleep does little to protect your mental health, and it’s also a real barrier to business success. That’s because in checking and responding to email so frequently and habitually, we’re building our agendas around everyone else’s goals, rather than our own. I know this all too well. I’ve lost days to my inbox, veering wildly off track and wondering where my original list of goal-related tasks went. But there’s a lot you can do to stop email controlling your life. Here are some suggestions: Take control with technology Technology itself is one of the answers. There are several apps that will automatically prioritise key emails, categorise others and filter out the stuff you really don’t want to see at all. (Obviously check with your colleagues in IT before installing software on a work computer.) For example, I’ve been using Sanebox, an intelligent system that files emails based on my history and behaviour, for over a year and it’s made a huge difference. It puts emails from addresses it can’t find in my contacts list into separate folders, saving my inbox only for messages it thinks I need to see. Then it emails me a digest once a day to tell me they’re there. (I can check the folders any time.) Gmail, Yahoo, Outlook and Apple mail also have helpful functions built in that are worth exploring. They’re less sophisticated, but free. WeekWill goes one step further. It sends you a text and can even call you if you get an email from anyone on your VIP list, so that you can switch off your mail app altogether. You can then check any critical emails using webmail (which, as it involves an extra step, is less tempting). This revives the prospect of email-free holidays. Remember those? Change your habits You don’t have to use a technical fix. You could try restricting yourself to checking and responding to email for half an hour, say, three times a day. If that works, you could then whittle it down to twice, or even once a day. For this to work, be sure to set an autoresponder to let correspondents know that’s what you’re doing. But be careful to word the automatic response sensitively or you’ll simply irritate people. Bluntly telling them that you check your email only twice a day will probably do more harm than good. (I’ve received emails like that and I confess it made me feel like the sender valued their time more than mine, even though I wanted to spend money with them.) Instead, you could write something like this: So that I can focus on doing the best work for my clients, I check email just twice a day, at around midday and 3pm. Then, throw them a lifeline, just in case: If you need to speak to me urgently, don’t worry. Just send me a text or call me on †¦ Most people will be happy to wait once you’ve reassured them in this way. This method needs real discipline, though. You need to use these half-hour periods for quick replies only. An email that takes an hour to respond to is a task in its own right. So try to recognise such messages and acknowledge that you need to plan them in properly (sending a holding reply if necessary). Take back your day Whatever you do, do something. It’s not sustainable to let email hijack your agenda every day. It will seriously restrict your progress and could damage your mental health.

Assess the impact of international business on social and economic Research Paper

Assess the impact of international business on social and economic conditions in bangladesh - Research Paper Example Workers were forced to go to the streets to fight for their rights which they thought were being infringed. The government formed wage board with the help of international labor organization stepped in to assist in the crisis. December last year the wage board approved a 77% increment in wage in the garment industry though most factory owners opposed it they had to oblige. As much as their right was granted, another problem arose. According to (Lazear, 15) the increase in minimum pay pushed the production cost since labor is the most valuable asset in production. On a business perspective, this was tragedy especially international trade. Price and quality of a product are correlated in international market and therefore, sound decision should be made before implementation. The increased minimum wage paved way for China, India, Turkey and Indonesia to surpass Bangladesh in the exportation of garment. According to (AP Worldstream, 7) This was attributed to the increase in the price of her garment which was expensive as compared to her competitors. This will impact on Bangladesh since she will experience unfavorable balance of payment i.e. high value of import as compared to export. Bangladesh being a developing country faces the problem of inequality in wealth distribution. In Bangladesh, the social class differs on extreme scenario such that we have those who are extreme poor and those who are â€Å"stinking† rich. People living around urban areas like Dhaka enjoy a quality life as those who live in the rural area. However, this doesn’t mean that all Dhaka inhabitants enjoy lucrative lifestyle, also in Dhaka there are shanties (Vietnamese News Agency, 4). In these shanties, the sanitation is compromised though they enjoy some benefits like availability of electricity and water. Inequality in wealth distribution has an impact to business development of a nation. With this widening gap between the rich and the poor in

The life of an international student Research Paper

The life of an international student - Research Paper Example The basic reason as to why most people become international students is that the education standards in their home countries do not meet their needs. As a result, these students opt to learn in other countries whose education matches their expectations. However, in most cases, it is not easy to settle down in a foreign country as an international student. For some, the change is too overwhelming and they may opt to go back home, while others persevere and work towards achieving their goals and dreams. Luckily, some countries like the United States and Canada have programs in their universities and colleges that help international students cope with the new life. The life of an international student The transformation that an international student undergoes once they move to a foreign country cannot be understated. In most cases, being an international student means leaving your family and friends behind and adjusting to a completely new lifestyle. One is forced to learn a new languag e, learn the culture of the people, adjust to their schooling system and basically learn how to live in a new country. Before getting used to these changes, most international students feel like aliens, thus preferring to keep to themselves as they assess the people around them. With time, however, they start looking for other international student from their home countries so that the latter can help them adjust. ... Differences between the United States and the Saudi Arabian systems of education One of the challenges that international students face is the difference in education systems between their home countries and their host countries. For example, the education system of the United States differs from that of Saudi Arabia in a number of ways. One of the differences, for example, is in regard to the conduct of students in class. At the beginning, I was always the quite type in class because that is the culture of Saudi Arabian classrooms. The students in Saudi Arabian classes do not speak much but in America classrooms, the story is different as students are very opinionated. They also challenge the teachers directly in case they do not agree with what the teacher says. In addition, whereas Saudi Arabians are very disciplined in class, in terms of modes of dressing and behavior, American students have a lot of freedom. For example, students come to class in casual clothes and some even tak e snacks and sleep in class. Additionally, being from Saudi Arabia, I was accustomed to official dressing while attending class, and a lot of discipline during sessions. I, therefore, always felt odd when I went to class dressed formally and almost everyone else was in casual wear. Although I have tried to adapt to the American classroom culture, is still find myself being formal in dressing as I attend class and reserving some of my opinions during lectures. In addition to the classroom setting, I was also confused at the beginning because the American system seems to place so much emphasis on education and leaves little space for socialization. Here in the United States, one is expected to either be in class, in a study group, doing research, or participating in

Analysis of Using Feedback Loops to Explain the Circadian Oscillator Assignment

Analysis of Using Feedback Loops to Explain the Circadian Oscillator in Drosophila Paper - Assignment Example However, there is a considerable delay between when the peak levels of the per and tim mRNA are synthesized and when per and tim levels reach peak production late in the evening. The reason for this is the phosphorylation that destabilizes the PER, causing it to undergo dimerization with TIM. This occurs in the nucleus. There is little that is known with regards to how dClk mRNA is regulated. Previous studies have found low quantities of dClk mRNA in Drosophila that do not have functioning PER and TIM, indicating that PER and TIM are also responsible for activating dClk. This study involved measuring the levels of dClk mRNA levels in various mutant gene combinations. The results showed that the mutant genes did not display highly varying quantities of dClk mRNA over the circadian clock (Glossop, Lyons, and Hardin). The lack of dClk-dependent-PER alongside the relatively high levels of dClk mRNA proves that PER-dependent dClk is not activated by localization of an activator in the nucleus. mRNA quantities in the dClk mutants were measured to prove that the activation of dClk was not as a result of PER-TIM dimmers being formed due to low quantities of per and tim in dClk mutants. Results from this measurement found that the levels of dClk mRNA were almost similar to the peak level of dClk mRNA found in wild flies, proving that dClk is activated by PER-TIM via derepression. The negative feedback loop can be used to explain the observations made above. In this, the formation of PER-TIM dimers leads to sequestering of dCLK-CYC dimers that in turn hinder the CLK-CYC from functioning properly. This ultimately causes the derepression of dClk transcription. The reduction of PER-TIM quantities in the early hours of the morning causes dimerization of dCLK-CYC. These dimers cause repression of dClk, resulting in a reduction of dClk mRNA levels by the time the day ends.

Cryptography: Theories, Functions and Strategies

Cryptography: Theories, Functions and Strategies Abstract Digital signing is a mechanism for certifying the origin and the integrity of electronically transmitted information. In the process of digitally signing, additional information called a digital signature is added to the given document, calculated using the contents of the document and some private key. At a later stage, this information can be used to check the origin of the signed document. The mathematical base of the digital signing of documents is public key cryptography. This work presents the theory behind digital signatures, signature schemes and attacks on signatures and provides a survey of application areas of the digital signing technology. Moreover, there are lab exercises developed in Mathlab, to reinforce the understanding of this technology. 1. Introduction The Concise Oxford Dictionary (2006) defines cryptography as the art of writing or solving codes, however modern cryptography does not met this definition. Therefore, this work starts with a literature review defining some key concepts, like what cryptography and cryptographic system are and the different types of cryptographic system are presented. The other interesting and preliminary concept is the notion of cryptosystem functions which are also discussed in the introductory section. Furthermore, it is stated that public-key encryption represents a revolution in the field of cryptography, and this work poses some basic definitions on this topic trying to explain the theory behind. The rest of the literature review is concentrated on public key cryptography and it focuses on the theory behind digital signatures, signature schemes and attacks on signatures. And finally, the literature review presents a survey of application areas on digital signatures. One part of the contribution of this work, is an overview of the secure hash standard (SHS) and implementation of the secure hash algorithm (SHA-1), required for use with digital signature algorithms. The main part though, is the implementation of AES and RSA by utilizing Mathlab. The code of all these implementations is thoroughly discussed and explained in this work. Moreover, a comparison is also presented subsequently. 2. Cryptography The Greek words â€Å"krypt ´os† standing for â€Å"hidden† and the word â€Å"l ´ogos† that means â€Å"word†, are in essence the base from where the word cryptology was derived. As these words denote, cryptology can be best explained by the meaning â€Å"hidden word†. In this context, the original purpose behind cryptology is hiding the meaning of some specific combination of words which in turn would insure secrecy and confidentiality. This is a very limited viewpoint in today’s perspective and a wide range of security applications and issues now come under the term of cryptology (rest of the portion of this section will clarify this point of view). As field of mathematical science, Cryptology includes the study of both cryptanalysis as well as cryptography. On one hand, cryptography is a very broad term and represents any process used for data protection. On the other hand, the study of security related issues and the probabilities of breaking the cryptographic systems and a technique is known as cryptanalysis. By making reference to (Shirey, 2000), the field cryptanalysis can be best described as the â€Å"mathematical science that deals with analysis of a cryptographic system in order to gain knowledge needed to break or circumvent the protection that the system is designed to provide.† In simple words, cryptanalyst can be regarded as the opponent of the cryptographer i.e. he/she has to get around the security which cryptographer devised on his/her part. (Buchmann, 2004) claims that a cryptographic system (or in short a cryptosystem) describes â€Å"a set of cryptographic algorithms together with the key management processes that support use of the algorithms in some application context.† This is a diverse explanation that includes all sorts of cryptographic algorithms as well as protocols. However, hidden parameters like cryptographic keys may or may not be used by a cryptographic system (Delfs, 2007). Similarly, participants of the undergoing communication may or may not share those secret parameters. Thus, cryptographic can be classified into following three types: a cryptographic system in which no secret parameters are employed (called an un-keyed cryptosystem); a cryptosystem which makes use of secret parameters and at the same time shares the parameters between the participants (known as a secret key cryptographic system); and a system that utilizes the secret parameters, but not sharing them with the participants (call ed a public key cryptographic system) (Shirey, 2000; Buchmann, 2004). Cryptography aims at designing and implementing cryptographic systems and utilizing such systems which are secure effectively. The first a formal definition about the term cryptography dates from relatively past time. Back then, the approach known by the name â€Å"security through obscurity† was being used (Dent, 2004). There are a lot of examples based on this approach by which security of the system was improved by keeping internal working and design secret. Majority of those systems do not serve the purpose and security may well be violated. The Kerckhoffs’ principle is a very famous cryptographic principle which states that (Kerckhoffs, 1883): â€Å"Except for parameters clearly defined to be secret, like the cryptographic keys, a cryptosystem must be designed in such a way as to be secure even with the case that the antagonist knows all details about the system†. However, it might be noted that one important aspect is that a cryptosystem is perfectly securing theoretically grounds, but it may not remain the same when implemented practically. Different possibilities of generating attacks on security of such systems can arise while having the practical implementation (Anderson, 1994). Attacks which make use of exploitation of side channel information are the examples of such attacks. If a cryptosystem is executed, it can result in the retrieval of side channel information with unspecified inputs and outputs (Anderson, 1994). In encryption systems, the input is plaintext message plus the key, while the specific output is the cipher text. Thus, there are chances on information leakage. Power consumption, timing characteristics along with the radiation of all types are some examples in this regard. On the other hand, side channel attacks are the types of network attacks which extract side channel information. Since the mid 1990s there were many di fferent possibilities have been found by the researchers in order to build up side channel attacks. A few examples in this regard are the differential power analysis (Bonehl, 1997), and fault analysis (Biham, 1997; Kocher, 1999) as well as the timing attacks (Kocher, 1996). It is a very practical statement that any computation performed on real computer systems represents some physical phenomena which can be examined and analyzed to provide information regarding the keying material being employed. Cryptography does not help to cope with this situation because of the inherent nature of this problem. 2.1 Cryptosystem functions Other than the usual random bit generators as well as the hash functions, there are no secret parameters that are used in cryptosystem functions. These are the junketed functions that characterize the cryptographic system functions. In cryptographic functions, the elements used are usually one-way and it is difficult or almost impossible to invert them. This follows that it is easy to compute a cryptographic function whereas it is hard to invert the functions and also to compute the results of the relationships (Kerckhoffs, 1883). It is difficult to apply any mathematical method for inverting the cryptographic system functions in a way that will be coherent and meaningful. For example, a cryptographic system functions such as F: X → Y is easy to comfortably use mathematical knowledge to compute while it is hard to use the same to invert (Buchmann, 2004; Shirey, 2000). There are many examples of one-way functions that we can use to demonstrate the meaning of the cryptosystems. In a situation where one has stored numbers on the cell phone, computation of the same is possible and easy due to the fact that the names are stored in an alphabetical manner (Garrett, 2001). If one inverts the relationship of these functions, it will be impossible to compute because the numbers are not arranged numerically in the storage phonebook. It is notable that a lot of other things that we do in daily life are comparable to cryptosystem function in the sense that you cannot invert or undo them. For example, if one breaks a glass, the process is one way because it is not possible for these pieces to be restored together again (Goldreich, 2004). Similarly, when one drops something into water, it is not practically possible to reverse the action of dropping this item (Mao, 2003). The English corresponding action would be to un-drop the item as opposed to picking it. Cry ptosystem functions cannot be demonstrated as purely one-way and this is the branching point between cryptosystem functions and the real world of things and circumstances. The only one-way functions in mathematics can be exemplified by discrete exponentiation, modular power and modular square functions. Public key cryptography uses these functions in its operations but it has not been well documented whether they are really one-way or not. There has been debate in practice whether one-way functions really exist in the first place or not (Garrett, 2001). In the recent day cryptographic discussions a lot of care should be applied when referring to the one-way functions so as not to interfere or make false claims to the functional attributes of these parameters. There is a need to look for extra information and knowledge concerning one-way functions so that efficient and meaningful inversions are possible and mathematically coherent. Therefore, functions such as F: X → Y is considered to be a one-way function (Koblitz, 1994; Schneier, 1996). This follows that if F can successfully and coherently inverted, the need for extra information is needed. This will hence bring the notion of the meaning of the other parameters in relation to F. Computer science uses the hash functions in its operations. This is because these functions are computable and generates output dependent on the input that was used (Katz, 2007; Koblitz, 1994). 3. Digital signatures The public-key encryption presents a revolution in the field of cryptography and until its invention the cryptographers had relied completely on common, secret keys in order to achieve confidential communication (Smart, 2003). On the contrary, the public-key techniques, allow for the parties to communicate privately without the requirement to decide on a secret key in advance. While the concept of private-key cryptography is presented as two parties agree on a secret keyk which can be used (by either party) for both encryption and decryption; public-key encryption is asymmetric in both these respects (Stinson, 2005). Namely, in public-key encryption: One party (the receiver) generates a pair of keys (pk, sk), where pk is called the public key and ps is the private key, The public key is used by a sender to encrypt a message for the receiver, and The receiver uses the private key to decrypt that message. There three parts of information form part of public key certificate: Some naming information A Public key Digital signatures (this can be one or more) Encryptions and digital signatures were introduced to make the web transactions secure and manageable. The use of cryptographic techniques was applied to enhance and provide security layer such that the encrypted information and files would remain secure and confidential. Very frequently, a digital signature is mistaken with the inverse of a public-key encryption, but this is not entirely true. In the history, a digital signature could be obtained by reversing, but today in the majority of the situations this process would be impossible to be performed. Basically, a digital signature is a form of a mathematical scheme for signifying the genuineness of a digital message. A valid digital signature would provide a proof to the person that receives the message or the document that these information is indeed created by a specified sender. Moreover, it would prove that message or the document was not altered during the transportation. Digital signatures are usually used for software distribution or mainly money transactions, where it is very important to detect the possibility of forgery. As a part of the field in asymmetric cryptography, it might be noted that a digital signature is somehow equivalent of the traditional handwritten signatures. On the other hand, in order to be effective, a digital signature should be correctly implemented. Another very important concept is the notion of non-repudiation. This means that if somebody signs a document by using a digital signature, they can not say that it was not signed by them, even though their private key remains as a secret. On the other hand, there is a time stamp, so that even if the private key of a sender is compromised in future, the digital signature will remain valid. Examples of such messages are: electronic mail contracts messages sent via some cryptographic protocol A digital signature usually is comprised of: An algorithm for producing a key. This algorithm would find a private key by chance from all the possible private keys available. Then it will output that private key with a matching public key. A signing algorithm that, given a message and a private key, produces a signature. A signature authenticating algorithm that, given a message, public key and a signature, it will accept or reject the message. Primary, a signature produced from a fixed message and a private key verifies that the genuineness of that message is ok, by means of the matching public key. Then, it has to be computationally infeasible to make an appropriate signature for a party that doesn’t have the private key 4. Algorithms 4.1. Introduction to SHS This section provides an overview of the secure hash standard (SHS) and implementation of the secure hash algorithm (SHA-1), required for use with digital signature algorithms. SHA-1 is used for computing a compressed version of a message or a data file. If that data has a length smaller than 264 buts, then the output will be 160-bit and is called a message digest. The message digest used for an input to the Digital Signature Algorithm (DSA). This algorithm will verify the signature for the message. Signing the message digest instead of the originall message itself, might advance the effectiveness of the procedure. This is since the message digest is usually much slighter in size than the original message. Very important is that the same hash algorithm should be used by both the verifier and the digital signature creator. The usage of the SHA-1 with the DSA can be presented as follows: Interesting for SHA-1 is that it is computationally impossible to discover a message which matchs to a given digest. Moreover, it is also impossible to find two dissimilar messages which create an identical message digest. 4.2. Implementation of SHA-1 The following functions were implemented for the SHA-1 algorithm: Name of source file: secure_hash_algorithm.m. Function in the source file: secure_hash_algorithm (message). This function takes an input a string of characters. Example: Hello, How are you? How is it going on? Output is the message digest, the hash value of the message. Thus, the hash value of the above message is F418F52AE6DC208599F91191E6C40FA876F33754. Name of source file: arithematic_shift_operations.m. Function in the source file: arithematic_shift_operations (number, position, op). The inputs are: number: it is a hexadecimal large number of any size. The number is represented in base 16 and is stored as a string. Ex: ‘FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF’ position: the number of positions to be shifted by. It is a decimal number in base 10. Op: it is the type of operation done. Inputs are ‘SRA’ -> shift right arithematic and ‘SLA’ -> shift left arithematic. For example, the function: arithematic_shift_operations(‘FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF’, 3, ‘SRA’) would return ‘1FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF’, and arithematic_shift_operations(‘FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF’, 3, ‘SLA’) would return ‘FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF8’. Name of source file: bi2hex.m. Function in the source file: bi2hex (number). The input to this function is a vector of ones and zeros and the result is a hexadecimal output represented in string. For example, for the input â€Å"Number = [1 1 1 1]† bi2hex (Number) returns ‘F’ and for â€Å"Number = [1 1 1 1 0 0 0 1 ]† bi2hex (Number) returns ‘F1’. Name of source file: hex2bi.m. Function in the source file: hex2bi (number). The input to this function is a number stored in form of a string in base 16 and the result is a vector containing the binary representation of input string. For example, for the input â€Å"Number = ‘F’ †, hex2bi (Number) returns â€Å"[1 1 1 1]† and for â€Å"Number = ‘F1’ â€Å", bi2hex (Number) returns â€Å"[1 1 1 1 0 0 0 1]†. Name of source file: hexadecimal_big_number_adder.m. Function in the source file: hexadecimal_big_number_adder (number_one, number_two). The inputs to this function are numbers stored in hexadecimal string format. Output is the result, a hexadecimal string and carry, a decimal number. After using this function, it has to be checked if the carry is generated, Incase if it is generated then the carry has to be appended in the beginning to the result. For example: Number_one = ‘FFFFFFFF’ Number_two = ‘EEEEEEEE’ [result, carry] = hexadecimal_big_number_adder (Number_one, Number_two) Result = ‘EEEEEEED’ , carry = 1; Hence the real sum is Result = strcat(dec2hex(0), Result); this results to ‘1EEEEEEED’ Name of source file: hexadecimal_big_number_subtractor.m. Function in the source file: hexadecimal_big_number_subtractor(number_one, number_two). The inputs to this function are numbers stored in hexadecimal string format. Output is the result, a hexadecimal string and sign, a decimal number. If sign is -1, then the result generated is a negative number else is a positive number. . For example: Number_one= ‘EEEEEEEE’ Number_two= ‘FFFFFFFF’ [result, sign] = hexadecimal_big_number_subtractor(Number_one, Number_two) Result = ‘11111111’ Sign = -1. Name of source file: hexadecimal_big_number_multiprecision_multiplication.m. Function in the source file: hexadecimal_big_number_multiprecision_multiplication(multiplicand, multiplier). The input is a multiplicand stored in string format is a hexadecimal number. And so is multiplier. The output is a result and is stored in form of a string. For example: multiplicand= ‘EEEEEEEE’ multiplier= ‘FFFFFFFF’ hexadecimal_big_number_multiprecision_multiplication(multiplicand, multiplier) result is ‘EEEEEEED11111112’ Name of source file: comparision_of.m. Function in the source file: comparision_of(number_one, number_two, index). This function compares two numbers in hexadecimal format stored in form of strings. Always input index as decimal 1. Therefore, it: Returns 1 if Number_one > Number_two, Returns 0 if Number_one = Number_two, and Returns -1 if Number_one For example, if Number_one= ‘EEEEEEEE’ Number_two= ‘FFFFFFFF’, the result would be: comparision_of(Number_one, Number_two, 1) returns -1. Name of source file: hexadecimal_big_number_modular_exponentiation.m. Function in the source file: hexadecimal_big_number_modular_exponentiation (base, exponent, modulus). This function calculates (power(base, exponent) % modulus). Here the input base, exponent and modulus are hexadecimal strings of any size. For example: Base = ‘FFF’ Exponent = ‘EEE’ Modulus = ‘AAAA’ hexadecimal_big_number_modular_exponentiation (Base, Exponent, Modulus) returns ‘8BAB’ Name of source file: hexadecimal_big_number_multiplicative_inverse.m. Function in the source file: Z = hexadecimal_big_number_multiplicative_inverse(number_one, number_two). This function returns multiplicative inverse of number_two modulo number_one. If az = 1 (mod m) then z is the multiplicative inverse of a mod m. Here â€Å"number_one = m†, â€Å"number_two = a†, â€Å"number_one = ‘FFFF’ †, â€Å"number_two = ‘1235’ â€Å" andresult is ‘634D’, which in turn is the multiplicative inverse of number_two.Hence : (result * number_two) mod number_one = 1 Name of source file: hexadecimal_big_number_test_for_primality.m. Function in the source file: hexadecimal_big_number_test_for_primality(number). The input to this function is an ODD number stored in hexadecimal format as a string. This function returns 1 if the input is a prime and returns -1 if input is composite. Name of source file: power_of_two_conversion_to_hexadecimal.m. Function in the source file: power_of_two_conversion_to_hexadecimal(power). The input is the number, the power to which two has to be raised to. It is a decimal number and the output is a hexadecimal number in form of string. For example, power_of_two_conversion_to_hexadecimal(4) returns ‘10’ i.e 16 in decimal system. Name of source file: hexadecimal_big_number_division.m. Function in the source file: hexadecimal_big_number_division (dividend, divisor). This function returns quotient and remainder both in hexadecimal string format. The inputs to this function are strings of hexadecimal format. This function uses other two functions in turn which are defined in source file Get_multiplier.m, multiplication_by_single_digit_multiplier.m. Name of source file: remove_leading_zeros.m. Function in the source file: remove_leading_zeros (number). This function takes number in hexadecimal string format as input and removes the leading zeros in the string and returns it. For example, if â€Å"Number = ‘000000012345’ â€Å", then the function returns ‘12345’. Some of the most prominent functions are presented in Appendix A. 4.3. Introduction to MD5 The MD5 Message-Digest Algorithm is a extensively utilised in cryptographic hash functions. Basically this is the case for cryptographic hash functions with a 128-bit (16-byte) hash value. MD5 is used in many security applications, and in addition it is frequently used to check data integrity. An MD5 hash is typically expressed as a 32-digit hexadecimal number. The following figure represents a schematic view of the MD5 Message-Digest Algorithm. 4.4. Implementation of MD5 This algorithm would compute MD5 hash function for files. For example, if as input is given the d = md5(FileName), then the function md5() will computes the MD5 hash function of the file specified in the string FileName. This function will returns it as a 64-character array dwhere d is the digest. The following methodology that the MD5 algorithm was implemented: Initially, the function Digestis called. This function would read the whole file, and will make it uint32 vector FileName = C:\md5InputFile.txt [Message,nBits] = readmessagefromfile(FileName); Then, it would append a bit in the last one that was read from that file: BytesInLastInt = mod(nBits,32)/8; if BytesInLastInt Message(end) = bitset(Message(end),BytesInLastInt*8+8); else Message = [Message; uint32(128)]; end Consequetly, it will append the zeros: nZeros = 16 mod(numel(Message)+2,16); Message = [Message; zeros(nZeros,1,uint32)]; And a bit length of the original message as uint64, such as the lower significant uint32 first: Lower32 = uint32(nBits); Upper32 = uint32(bitshift(uint64(nBits),-32)); Message = [Message; Lower32; Upper32]; The 64-element transformation array is: T = uint32(fix(4294967296*abs(sin(1:64)))); The 64-element array of number of bits for circular left shift: S = repmat([7 12 17 22; 5 9 14 20; 4 11 16 23; 6 10 15 21].,4,1); S = S(:).; Finally, the 64-element array of indices into X can be presented as: idxX = [0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 1 6 11 0 5 10 15 4 9 14 3 8 13 2 7 12 5 8 11 14 1 4 7 10 13 0 3 6 9 12 15 2 0 7 14 5 12 3 10 1 8 15 6 13 4 11 2 9] + 1; The initial state of the buffer is consisting of A, B, C and D. such as: A = uint32(hex2dec(67452301)); B = uint32(hex2dec(efcdab89)); C = uint32(hex2dec(98badcfe)); D = uint32(hex2dec(10325476)); The message is reshaped, such as: Message = reshape(Message,16,[]); The look between the blocks, such that X is an extraction of the next block: for iBlock = 1:size(Message,2) X = Message(:,iBlock); The buffer states are stored as: AA = A; BB = B; CC = C; DD = D; The buffer is transformed by utilizing the X block from above, and the parameters from S, T and idxX k = 0; for iRound = 1:4 for q = 1:4 A = Fun(iRound,A,B,C,D,X(idxX(k+1)),S(k+1),T(k+1)); D = Fun(iRound,D,A,B,C,X(idxX(k+2)),S(k+2),T(k+2)); C = Fun(iRound,C,D,A,B,X(idxX(k+3)),S(k+3),T(k+3)); B = Fun(iRound,B,C,D,A,X(idxX(k+4)),S(k+4),T(k+4)); k = k + 4; end end The old buffer state is also being added: A = bitadd32(A,AA); B = bitadd32(B,BB); C = bitadd32(C,CC); D = bitadd32(D,DD); end The message digest is being formed the following way: Str = lower(dec2hex([A;B;C;D])); Str = Str(:,[7 8 5 6 3 4 1 2]).; Digest = Str(:).; The subsequent functionality is performed by the following operations: function y = Fun(iRound,a,b,c,d,x,s,t) switch iRound case 1 q = bitor(bitand(b,c),bitand(bitcmp(b),d)); case 2 q = bitor(bitand(b,d),bitand(c,bitcmp(d))); case 3 q = bitxor(bitxor(b,c),d); case 4 q = bitxor(c,bitor(b,bitcmp(d))); end y = bitadd32(b,rotateleft32(bitadd32(a,q,x,t),s)); And the bits are rotated such as: function y = rotateleft32(x,s) y = bitor(bitshift(x,s),bitshift(x,s-32)); The sum function is presented as: function sum = bitadd32(varargin) sum = varargin{1}; for k = 2:nargin add = varargin{k}; carry = bitand(sum,add); sum = bitxor(sum,add); for q = 1:32 shift = bitshift(carry,1); carry = bitand(shift,sum); sum = bitxor(shift,sum); end end A message is being read frm a file, such as: function [Message,nBits] = readmessagefromfile(FileName) [hFile,ErrMsg] = fopen(FileName,r); error(ErrMsg); Message = fread(hFile,inf,ubit32=>uint32); fclose(hFile); d = dir(FileName); nBits = d.bytes*8; Lastly, the auto test function is the following: function md5autotest disp(Running md5 autotest); Messages{1} = ; Messages{2} = a; Messages{3} = abc; Messages{4} = message digest; Messages{5} = abcdefghijklmnopqrstuvwxyz; Messages{6} = ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789; Messages{7} = char(128:255); CorrectDigests{1} = d41d8cd98f00b204e9800998ecf8427e; CorrectDigests{2} = 0cc175b9c0f1b6a831c399e269772661; CorrectDigests{3} = 900150983cd24fb0d6963f7d28e17f72; CorrectDigests{4} = f96b697d7cb7938d525a2f31aaf161d0; CorrectDigests{5} = c3fcd3d76192e4007dfb496cca67e13b; CorrectDigests{6} = d174ab98d277d9f5a5611c2c9f419d9f; CorrectDigests{7} = 16f404156c0500ac48efa2d3abc5fbcf; TmpFile = tempname; for k=1:numel(Messages) [h,ErrMsg] = fopen(TmpFile,w); error(ErrMsg); fwrite(h,Messages{k},char); fclose(h); Digest = md5(TmpFile); fprintf(%d: %sn,k,Digest); if ~strcmp(Digest,CorrectDigests{k}) error(md5 autotest failed on the following string: %s,Messages{k}); end end delete(TmpFile); disp(md5 autotest passed!); 4.4.1 Results This algorithm is tested with the input: university of Portsmouth department of electronic and computer engineering.

Introduction to Caesar cipher The Caesar cipher in cryptography, is in essence a shift cipher. It represents as one of the simplest and most widely known encryption methodologies. The Caesar cipher is a kind of substitution cipher. It means that each letter in a given plaintext is replaced by another letter. This is done due shifting by some fixed number of positions down the alphabet. Julius Caesar was the first to use this ci

Ben Cohen’s “Ben and Jerry’s”

Due to the societal shift in the twentieth century toward material gain and capitalism, there has been an overwhelming emphasis put on monetary accrual and the pursuit of wealth. To generalize, people are no longer satisfied with familial happiness and achieving status through such things as cars and clothes has become the norm. Due to this, the job market has become increasingly more competitive, which in turn has given tremendous power to business. Corporations have all but taken over control of the distribution of assets. Ben Cohen, co-founder of Ben and Jerry's writes, â€Å"Corporations have been granted the right to become the major depositories and bestowers of wealth in our society.† Businesses, whether they want to or not, have a tremendous impact on the economic and social status in the world. The underlying problem with this relatively recent shift is that too often is the case that larger corporations neglect to acknowledge the potential danger they pose to the environment and the society as a whole. Therefore, it is the duty of each and every enterprise to take into account the tremendous power it possesses and act in such a way that is not detrimental to society. Unfortunately, as history teaches us, too many businesses take the â€Å"its not my problem† attitude and the result is often times irreversible. Since 1978, Ben Cohen and Jerry Greenfield have accepted the fact that indeed companies have the capacity to have a tremendous influence on the economy and ecology, and done everything possible to make theirs a positive one. To run a successful business, several factors must be kept in mind at all times. The business must function efficiently and at the same time produce a quality product. The consumer's interests also must be taken into account, and too often overlooked is the necessity to maintain a satisfied work force, making them feel important and needed. The Ben and Jerry's corporation, but a small two man operation running out of a gas station twenty years ago, has always rendered these qualities vital, no matter what their circumstance was. The two men met in 1963 as seventh graders in a small Long Island gym class. Ben, a native of Brooklyn, New York, attended Colgate University for only a year before dropping out to return to his high school job as a neighborhood ice cream man. He had a brief stint at Skidmore College as well as NYU, and moved to upstate New York before going into business with his partner and long time friend Jerry Greenfield. Jerry was also born in Brooklyn and after high school attended and graduated from Oberlin College. After being rejected form medical school twice and moving to North Carolina, he and Ben decided to make their dream a reality. They decided to move to Vermont, and with a $12,000 investment opened a small homemade ice cream shop in downtown Burlington. When the business began Ben and Jerry sat down and had rather basic goals. Their credo was â€Å"If it's not fun, why do it?† They wanted to enjoy themselves while earning a living, and at the same time give something back to the community. As business began to take off, they needed to set down guidelines in order to achieve all three goals. Ben and Jerry execute what is referred to as a values-led business. â€Å"Values-led business is based on the idea that business has a responsibility to the people and the society that make its existence possible. More all-encompassing and therefore more effective than philanthropy alone, values-led business seeks to maximize its impact by integrating socially beneficial actions into as many of its day-to-day activities as possible*By incorporating concern for the community – local, national, and global * into its strategic and operating plans, the values-led business can make everyday business decisions that actualize the company's social and financial goals at the same time.†(Ben and Jerry's Double-Dip, p.30) Their mission statement, due to the type of company they desired was broken down into three separate parts (p.46): Product Mission: to make, distribute and sell the finest quality product Social Mission: to operate the company in a way that actively recognizes the central role that business plays in society by initiating innovative ways to improve the quality of life of the local, national, and international community Economic Mission: to operate the company on a sound fiscal basis of profitable growth This method of business and sense of mission allows Ben and Jerry's to do several things. The business naturally holds profit and success as a priority, but at the same time acknowledges and does its best to help the community and its surroundings. Ben and Jerry's current CEO, Perry Odak, says that he originally â€Å"sought out the company because of its excitement about combining social endeavors with a growing, profitable business.†(p.188) The management in Ben and Jerry's is very people oriented. If run properly, values-led businesses often yield an incredibly motivated workforce. â€Å"If people understand that the work they do produces more than just profits, and they're in alignment with the values of the company, there's no end to what they can contribute.†(p.165) The management at Ben and Jerry's has always strived to keep the employees happy and emote a real sense to the staff that indeed they are important. â€Å"Values-led management aspires to respect employees and seeks to meet their needs as well as the needs of the company.†(p.167) Instead of having top level management be distant and authoritative, the management at Ben and Jerry's is very involved with the employees. Their employees are often surveyed, every eighteen months in fact, on how they feel the company is doing, their thoughts on improving products and management, and how happy they are. Because of this, the workforce at Ben and Jerry's remains quite content, and never feels too distant from top level executives. Management in 1985 implemented what they call a five-to-one salary ratio, which limits the top executive salaries to five times the lowest salary. This idea ensured that as the company prospered, so too did everybody working for the company. Management at Ben and Jerry's has established a list of what they call â€Å"Our Aspirations,† in order to constantly remind themselves not only their goals but what they are in business for. They are fourteen mini-objectives that clearly exhibit to the management what needs to get done and the way in which to do. Briefly, each one(compiled from pp.173-175): To Be Real * actions speak louder than words; be the company that they claim to be To Be the Best * plain and simply, want to be the best ice cream company in the world; if the customers are satisfied with the product, the company will prosper and they'll outperform the competition To Improve Continuously * each time a goal is accomplished, a back check should be done to look for ways of improving upon methods for next time To Learn Continuously * employees constantly should receive training in all areas so their contribution to the company increases To Be Inclusive * people of all backgrounds work for Ben and Jerry's and each one's individuality is embraced and creates a tight knit group To Be Creative * creativity excites customers and naturally helps business To Build Community * no employee of Ben and Jerry's feels alone and everyone on the staff would extend a hand to another employee To Be Open and Trusting * if everyone trusts one another, people feel a lot safer about sharing their opinions and ideas, therefore strengthening the company To Celebrate and to Give Meaningful Recognition * when goals are acomplished, they should be acknowledged; recognition of achievements will only lead to more achievements To Use Consultive Decision Making and Active Listening * people of certain expertise are often employed to help make decisions; leaders of the company also must be take into account employee opinions To Hold Ourselves Accountable * if everyone does their job and takes care of their responsibility, the company will run smoothly To Be Great Communicators * leaders of the company always need to make sure that their staff is well informed of whatever needs to be done To Be Upfront * people need to be directly told what to do and avoiding roundabout communication is vital To Be Profitable by Being Thrifty * when the company invests, they need to be careful about how mow and where they invest. Saving the company money is beneficial to stockholders and employees Rather than hiring outside help for new job openings, Ben and Jerry's hires from within the company, promoting people up through the ranks and delegating more responsibility. In the beginning, when new employees were being hired, management demonstrated the company's goals and methods to the new members, and let them know what their particular responsibilities were to be. In this way people had a clear understanding of the company's direction and what they needed to do in order to be promoted. Unlike many big companies, Ben and Jerry's recognized that the most important asset to their company was its employees, and that is one of the biggest reason that they became so successful (see graph at end). Because of this, Ben and Jerry's offers a wide array of benefits to its employees, realizing the high costs of living in this day and age. Because Ben Cohen and Jery Greenfield believed in themselves and their ideas, their company as become quite successful, accumulating numerous accolades. At the same time, they have not neglected their social duty and have contributed greatly to the society. In 1985, they established the Ben and Jerry's Foundation which is allotted 7.5% of the company's annual pre-tax profits for supporting various community oriented projects. Because of this foundation, they were awarded the Corporate Giving Award form the Council on Economic Priorities in 1988. In '91 held voter registration in their stores and got 1500 more Vermont residents to register. When the Newport Folk festival was in danger due to a lack of a sponsor, Ben and Jerry's took up the reins. They helped to establish a movement to redirect 1% of the U.S. defense budget to fund peace-promoting projects. They received Columbia University's Lawrence A. Wien Prize for corporate Social responsibility. They supported family farmers by printing an 800 number to call on their pint cups. Frankly, the list goes on and on. By sticking to their preset guidelines and objectives, Ben and Jerry's was and still is able to maintain a lucrative business that is great to its employees and beneficial to society.

Queen Elizabeth Ra Speech

Queen Elizabeth Rhetorical Analysis Essay Queen Elizabeth’s purpose with her speech is to help boost morale and show her support for the troops. She achieves this by speaking with such tenacity and by appealing to her soldier’s sense of nationalism. Elizabeth says she’s willing to lay down her life for the country she loves, as the men in front of her are about to do. Through this statement she is able to establish a connection with the troops, an example of Pathos, as she appeals to their love for England.The reason for this is to show the troops that she respects each one of them for the price they may have to pay for such a noble sacrifice. At the end of the speech she calls her enemies the enemies of God, England, and her people, and uses the word my in front of all three examples. The use of â€Å"my† shows that she takes ownership of these things and, as all good owners should do, shows that she plans to protect these things. Another way Elizabeth co nnects to her troops is by offering them monetary rewards for their actions.She also says that they are guaranteed by the word of prince, because in this time period, men were superior to women. Although she is Queen and it matters little that she’s a woman, the use of â€Å"prince† is highly significant because she basically refers to herself as equal to a man. This makes her men see her equal and respect her even more. Queen Elizabeth uses these ways to connect to her troops in order for them to be able to fight well in the upcoming battle.

How to Cure a Hangover After a College Party

How to Cure a Hangover After a College Party The history of alcohol is a bit sketchy. While no one knows exactly when the first alcoholic drink was developed, archeologists have found proof of a fermented drink made from rice, honey and fruit being consumed 9,000 years ago. The date alcohol was invented may not now be known but one thing is – the following day the hangover was discovered. Since then, people have been searching for the perfect fix. Top 5 Hangover Cures Here weve collected the Top 5 Hangover cures history has to offer as well as a look back to some that have (thankfully) stayed buried in the past. H2-Oh My Aching Head Whatever hangover cure you try, be sure water plays a role. Alcohol dehydrates your entire body and what it really needs is to replace that lost fluid. So begin your day by sipping – not chugging – a tall glass of water. Pro tip: drink water in between alcohol drinks. Toast Tea The healing powers of a simple breakfast have long been heralded as a hangover cure. In 1896, writer Guy Beringer wrote an article extolling the virtues of a mid morning meal as a hangover cure. He insisted it would make life brighter for Saturday-night carousers and could sweep away the cobwebs of the week. While the thought of food may not be especially appealing first thing The Morning After, having some carbs in your stomach can help ease the roller coaster of nausea. Including a beverage like plain tea or even ginger ale can also help to settle the stomach. Plop, Plop, Fizz, Fizz Effervescent tablets like Alka Seltzer have been a hangover standby for years. The fizzing bubbles and sodium bicarbonate (aka Baking Soda) will help to settle your stomach but make sure you dont bolt the glass down like a shot. The aspirin and citric acid could irritate your stomach if you drink it too fast. Get in Touch With Your Feminine Side Taking pain relievers developed for PMS can help with hangovers as well. Pain killers include a mix of pain relievers, diuretics and caffeine to help with cramping, pain and bloating. Each of them also helps to alleviate the symptoms of a hangover more effectively than pain relievers on their own. Gentle Exercise While this isnt the time to start training for your Iron Man marathon, some slow and gentle exercise can help the Morning After. Do something simple like stretching or a short walk to get your blood moving. This should only be done once youve had some water and a small amount of food. If you begin to feel dizzy or nauseous, rest and have some more water before trying it again. Weird Hangover Cures From History Every culture has their own rich history of how to cure a hangover. Throughout history, every corner of the globe has offered up their own version of a magical cure. While these five cures have stood the test of time to achieve mainstream acceptance, other cultural cures havent quite caught on. An ancient Scottish cure is called the Highland Fling. Heat a pint of buttermilk and add in a tablespoon of cornstarch. Season with salt and pepper and drink while still warm. Romanians swear by eating tripe – a cows stomach boiled in a salty vegetable broth and seasoned with vinegar and cream. Some swear it cures a hangover by expelling the poisons while others insist the thought of having to have it the next morning keeps your drinking under control the night before. One home remedy from Puerto Rico calls for the patient to run a slice of lemon or lime under their drinking arm before they head out for the night. The Ancient Romans – notorious for the drinking and excess – prescribed a breakfast of sheep lungs and owl eggs to cure the morning after headache.

Free Essays on Bogus Parts

With aircraft inventories aging, â€Å"bogus† aircraft parts have become a serious problem for commercial and civil aviation on an international scale. The high cost of approved aircraft parts and relatively lax enforcement have created a lucrative market for criminals to introduce counterfeit and misrepresented aircraft parts into every facet of the aviation industry. The aviation industry has dubbed aircraft parts as â€Å"bogus† which are fraudulent knock-offs, parts with misrepresented age, parts with prior crash damage, or parts with misrepresented composition(such as parts made of an inferior alloy). The Federal Aviation Administration has placed â€Å"bogus† parts in the much broader category of â€Å"unapproved parts†. The category of unapproved parts can contain â€Å"bogus† parts as well as legitimate parts that are misused and legitimate parts that have merely an incorrect paper-trail. The Federal Aviation Administration contests that a vast majority of unapproved parts are legitimate aircraft parts with incorrect or insufficient paper-trails. Many critics have accused the Federal Aviation Administration of using the innocuous category of unapproved parts as an attempt to hide the serious problem of â€Å"bogus† parts from the flying public. As reported by BusinessWeek magazine: â€Å"The FAA allegedly pressured the NTSB to stop listing bogus parts in its database as a possible cause of crashes, according to four independent sources: a senior FAA official, as well as sources in the Transportation Dept., the airline industry, and congressional staff.† The Federal Aviation Administration maintains that they did not pressure the NTSB and recommended the changes to make the database more accurate. Currently no accidents are listed with the probable cause of â€Å"bogus† parts. One aspect pertaining to the success of â€Å"bogus† parts sales is the potential savings to maintenance departments and the potential profit to parts b...

Survey Of Agile And Waterfall Integration In Financial Services Thesis

Survey Of Agile And Waterfall Integration In Financial Services - Thesis Example They adopt and use strategic systems and processes in developing the software as would be necessary depending on the type and purpose of the software being developed. It is however, worth noting that there is disparities that would be identified in the processes and technologies used in software development over years. For instance, the advancement of technology has seen the evolution of skills and expertise in the field to have advanced the traditional technologies to the more efficient and effective technologies of software development as we have them today. Future projection also points towards improved systems and processes to be devised for the process of software development in the future. It is therefore basic and necessary to be aware that the process of software development is very dynamic and keep evolving. In order to ensure that the continuous changing nature of software development does not result in a haphazard approach to developing software, software developers have often used specific modules of software of development, prominent among which is the use of the systems development life cycle (SDLC). According Larman (2004), system development life cycle is a form of application development life-cycle that is used for achieving integrated purposes in software development, including the purposes of planning, creating, testing and deploying information systems within organizations. SDLC has largely been used in direct association with software development. This notwithstanding, Leffingwell and Widrig (2010), actually emphasized that as a system development model, system development life-cycle is good for hardware configuration, as much as it is good for software configuration. Larman (2004) also wrote about the numerous benefits that SDLC offers software developers, emphasizing that it is integrative, meaning that it guarantees the

The 1968 Theft Act Assignment Example | Topics and Well Written Essays - 1000 words

The 1968 Theft Act - Assignment Example This research will begin with the statement that the 1968 Theft Act was supposed to come with simplified rules and policies that were meant to eliminate the many dilemmas and confusions that criminal lawyers had faced earlier. Unfortunately, soon after its introduction into the legislation more complexities started to arise. It appeared that most of the concepts that were designed to bring out clarity in theft cases turned out to bring more confusion following the various proceedings that advanced from there henceforth. The most controversial concept being appropriation which had been introduced into the law to simplify things by replacing taking and carrying away. The term was defined in partiality by section 3 (1) of the Theft Act. Lack of further explanation on the term by the legislative is what caused more problems. Two issues arose:Â  one is what the relationship between consent and appropriation was and the second, the possibility of appropriating property that was acquired i n a transaction impeccable at civil law. This essay tries to analyze these facts using issue raised in two important cases R v Hinks and DPP v Gomez. The researcher of this essay also utilizes Shute’s views from his article Appropriation and the law of theft. The purpose of this research is to investigate the following: consent and appropriation; unimpeachable transfers and appropriation and evaluation of arguments Hinks case.... 41). There are other valid reasons where a transaction is censured at common law on a number of certain defined grounds. These can be where the transaction is a product of duress, and it may have been through deception, undue influence, fraud, or misrepresentation (Horder & Shute, 1993, p. 549). Sometimes the transaction can be vitiated to have occurred because there was enough reason to believe one party was unconscious. In the event that any of the above occurs then the transaction should remain valid until the transferor repudiates it successfully. Unimpeachable Transfers and Appropriation This issue arises where a transfer of property is unimpeachable at both equity and at common law. This matter arose in Mazo (1997) case where a house cleaner took advantage of her employer’s mental incapability to dishonestly receive and cash cheques made payable to her by her boss. The house cleaner was sentenced to Jail after being found guilty for five counts of theft and one count of attempted theft. On her appeal, the court held it that the case was consistent with that of Lawrence v Metropolitan Police commissioner (1972) where the House of Lords decision was that in the event a valid gift was made then there could be no theft. However, it was not clear as per Viscount Dilhorne’s speech in the Lawrence case whether the House of Lords could not charge the receiver of the gift with theft, which was consistent with the ruling in Gomez case. This decision was later addressed in the case of Hinks that happened two years later after the Gomez and Lawrence cases. In Hinks case, he was convicted of five counts of theft despite his argument that the sums received were gifts and loans therefore could not be appropriated
