Paradox of Samsungs Rise free essay sample

The Paradox of Samsungs Rise, examines the strategic management decisions that ed to Samsungs emergence as one of the worlds most successful companies from an ordinary original equipment manufacturer Just 30 years ago. Samsung Electronics transformed itself through a new management initiative in 1993 that combined Western best-practices with essentially Japanese management methods to produce a highly profitable hybrid system, resulting in recording breaking profits of Sl billion on $138 billion in revenue in 2010. As todays emerging giants face the challenge of moving beyond their home markets, they have much to learn from the path breaking xperience of South Koreas Samsung Group, arguably the most successful globalizer of the previous generation. Abstract: Twenty years ago, few people would have predicted that Samsung could transform itself from a low-cost original equipment manufacturer to a world leader in RD, marketing, and design, with a brand more valuable than Pepsi, Nike, or American Express.

For two decades now, Samsung has been grafting western business pracuces onto Its essentlally Japanese system, comDlnlng Its traaltlonal low-cost manuTacturlng rowess with an ability to bring high-quality, high-margin branded products swiftly to market. Like Samsung, todays emerging giants†Haier in China, Infosys in India, and in Turkey, for instance†face a paradox: their continued success requires turning away from what made them successful. The tightly integrated business systems that have worked in their home markets are unlikely to secure their future in global markets. Samsung has steadily navigated this paradox to transcend its initial success in its home markets and move onto the world stage. To move to the next evel, they, too, must reinvent themselves in ways that may seem contradictory. And when they reach new plateaus, they will need to do so again. For seven years, we have traced Samsungs progress as it has steadily navigated this paradox to transcend its initial success in its home markets and move onto the world stage. It is a story we believe holds many important lessons for the current generation of emerging giants seeking to do the same. The Rise of a World Leader: The two sets of business practices could not have seemed more incompatible. Into an organization focused on continuous process improvement, Samsung introduced a ocus on innovation. Into a homogeneous workforce, Samsung introduced outsiders who could not speak the language and were unfamiliar with the companys culture. Into a Confucian tradition of reverence for elders, Samsung introduced merit pay and promotion, putting some young people in positions of authority over their elders. It has been a path marked by both disorienting disequilibrium and intense exhilaration. Founded in 1938, the Samsung Group is the largest corporate entity in South Korea, with $227. 3 billion in revenue in 2010 and 31 5,000 employees worldwide.

By 1987, when Lee Kun-Hee succeeded his father as only the second chairman in the companys history, Samsung was the leader in Korea in most of its markets. But its overseas position as a low-cost producer was becoming untenable in the face of intensifying competition from Japanese electronics makers, which were setting up anufacturing plants in Southeast Asia, and rising domestic wages in South Koreas newly liberalizing economy. In the early 1990s, Lee spotted an opportunity in the reluctance of Japanese companies†the analog market leaders†to adopt digital technology, which consumers were flocking to in cameras, audio equipment, and other electronic products.

Othello Act 5, Scene 2 - Analaysis

'Othello' Act 5, Scene 2 - Analaysis We continue our Othello Act 5, Scene 2 analysis. You can get more information on the first part of this scene here.   Act 5, Scene 2 (Part 2) Othello explains that Iago told him that she and Cassio were having an affair and that Cassio himself admitted it and had the handkerchief; the token of love he gave to Desdemona passed down from his mother. On hearing this Emilia reacts; â€Å"O God! Heavenly God!† Realising her part in her husband’s plan, Emilia is moved. Iago orders Emilia to hold her peace but she refuses; telling the group that her husband asked her to steal the handkerchief for a reason unknown to her and that she did find it and give it to him. The Death ofEmilia Iago accuses her of lying and draws his sword on his wife. She says; â€Å"What should such a fool Do with so good a wife?† Othello runs at Iago calling him a villain. Montano disarms Othello and Iago wounds his wife. Emilia asks to be laid next to Desdemona to die. Iago exits. Montano goes after Iago and orders the others to guard Othello and not let him escape. Before she dies Emilia says; â€Å"Moor, she was chaste. She loved thee cruel Moor. So come my soul to speak true. So, speaking as I think alas, I die.† Othello is now consumed with guilt he finds a weapon hidden in his room but tells Graziano to approach him but not to fear him. He intends to use the weapon on himself. He looks at Desdemona’s cold body and curses himself. Othello wounds Iago Lodovico enters with Iago, Montano and Cassio in a chair. Othello stands forward as Iago is brought to face him. Othello wounds Iago. Lodovico orders the attendants to disarm Othello. Othello is unrepentant about hurting Iago, Lodovico reminds him that he was a respected soldier and Othello says that he acted in honour rather than in hate. He admits to consenting to Cassio’s death. Cassio says that he did Othello no wrong and Othello apologises to him. Lodovico says that two letters were found in Roderigo’s pocket, one says that Roderigo was ordered to kill Cassio and the other is written by Roderigo to Iago complaining about his evil plan. He says that he was going to expose the villain but Iago killed him off. The letter explains how he was ordered to goad Cassio on his watch, which is how the quarrel between Cassio and Othello first began. Lodovico tells Othello that he must return with him to Venice to answer to his crimes. Cassio is instated as ruler of Cyprus. Othellos Death Othello gives a speech to say that he wants to be remembered as a lover who was deceived. He wants to be remembered as someone who had a precious jewel but foolishly threw it away, he uses an analogy of a base character from an Indian tribe who threw away a precious pearl. He uses another reference to race when he says; â€Å".in Aleppo once, Where a malignant and a turbaned Turk beat a Venetian and tradused the state, I took by th’ throat and smote him thus†. He then stabs himself, kisses Desdemona and dies. Lodovico tells Iago to look at the consequences of his actions, he then closes the curtains. Lodovico tells Graziano that any riches in the house are his as he is the next of kin. He tells Cassio that he will leave Iago’s punishment to him and that he will return to Venice with the sad news of what has come to pass; â€Å"Myself will straight abroad and to the state This heavy act with heavy heart relate.† Note:  If you are looking for scene-by-scene analysis of other Othello scenes, simply visit our index  where you can find a full list of all scene by scene guides to  Shakespeares  Othello.

LBSMK 2004 SERVICES MARKETING personal evaluation project (PEP) Literature review

LBSMK 2004 SERVICES MARKETING personal evaluation project (PEP) - Literature review Example Yet, the causes of such dissatisfaction are varied and extensive. The concept of â€Å"satisfaction gaps† emerged from marketing research, which is the difference between customer expectations and their corresponding experience. This paper will attempt to propose a solution to such gap in a marketing-related problem of a service establishment. 2.0. Critical Analysis of the Issue and Literature Review 2.1. The Problem For the purpose of anonymity and confidentiality dictated by research ethics, the business establishment which will be discussed in this paper will be called simply as Company X (Bryman and Bell 2007). Company X is a technology service company whose specialisation is laptop, desktop and cellular phone repair. It was established in 2000 and is located in Eastern-Central Britain. The establishment showed good performance in its first three years of operation. This was mainly the reason why Company X was sub-contracted by a Northern European mobile phone company in 2 004 to serve its clientele in the geographic area covered by Company X, for repair and replacement of parts, if necessary. Subcontracting with the mobile phone company lifted the spirits of both management and technicians. The technicians performed well and helped generate both revenue and more patrons for Company X. Mobile phones which were already off-guarantee period were still being brought by former customers mainly because of their prompt service and technical know-how. Things went well for Company X that its sub-contracting functions with the mobile company was renewed for three-consecutive years. In 2008, a laptop and desktop manufacturer based in the North America commissioned Company X as one of its official service centres. Management was ecstatic. Its 10 best technicians were offered training packages to further hone their skills while the remaining 22 technicians were left to attend to the service needs of their growing clientele. Management promised that the rest of th e technicians will also attend training in two batches after the 10 have returned to resume their tasks. While the company operated for only 12 hours each day, technicians worked in three eight-hour shifts, or seven technicians per shift. When job orders increased to levels where the technicians can no longer put-up with the deadlines they set for completion of the service requests, management opted for overtime with pay instead of hiring new technicians. The rationale volunteered by management is that hiring new technicians will not ensure that deadlines will be met since they would not be sure if the applicants can deliver up to management expectations by simply looking at their resumes. With an additional sub-contracting project and fewer technicians to work on repair orders, problems started to surface. To date, absenteeism became rampant. Patrons are starting to be dissatisfied with the service jobs they requested. Technicians who used to be accommodating and interacted with cu stomers with a smile have turned grumpy. Customers have aired their complaints with customer service. The mobile company had threatened not to renew their contract if the customer service issues will not be addressed. In the operation manager’s latest quarterly report, revenue for the last month dropped by 40% of the previous six

Article Writing about FingerID Example | Topics and Well Written Essays - 1000 words

Writing about FingerID - Article Example echanism of authentication also compels the user to remember different passwords for multiple accounts since it is very dangerous to maintain the same password for all accounts. A new authentication mechanism has been proposed that will save the user from the hassle of remembering multiple passwords and provide effective security for the web services- FingerID. FingerID authenticates the users on the basis of their registered finger prints and provide single sign-in to multiple accounts. The advancement in the internet technology has enabled thousands of companies to offer their services online. The availability of the services attracts the users to utilize them but compels the users to make online accounts. This results in the presence of user’s personal information at different domains and organizations on the internet and multiple login credentials for the user. Every organization might not be following reliable security measures to safeguard the user information thereby creating security and privacy threats for the users. Some organizations deploy security measures for the storage of their data but fail to concentrate on the security mechanisms handling the exchange of data from one source to the other. The user’s information might be used for malicious purposes and result in identity thefts. The distributed nature of information increases the chances of inappropriate usage. Another issue that is faced with the existing web services is the lack of usability and accessibility. Usability makes the web experience more convenient for the user and accessibility introduces features and functionalities for users with disabilities. Most of the web services do not follow the standards that are meant to ensure the availability of accessibility and usability on the websites. These standards help the developers and designers evaluate their websites with respect to the usability and accessibility aspects and to ensure that their users do not face any difficulty in

Has the IMF played a condtructive or destructive role Does it serve Essay - 1

Has the IMF played a condtructive or destructive role Does it serve any purpose in the 21st century - Essay Example The IMF has grown and experienced changes over the last years. Many have embraced this change, while there has been some that have not accepted it. Its members have been increasing, from the initial thirty to over 188 members. This organisation claims to foster financial stability, global monetary corporation and economic stability to its members (Freytag pg 20-30). Its objectives are geared towards promoting international economic, Corporation, creation of employment, establishing sustainable exchange rate and availing funding to its member states. The role of the international fund about the 21st century is addressed by analysing the success and failure rate. Since its debut, this organisation has funded numerous nations, where there has been failure or success. The facts present a concrete factor that present this organisation as failing. Though there are success cases, the failures often lower the impact of these cases. One notable case is the one witnessed in Tanzania. After the IMF stepped in to save this declining economy, its economy lowered. The employment rate decreased and the literacy level dropped. All this occurred within period from 1985 to 2000 (Research Activities of the International Monetary Fund: January 1991-December 1998 pg 26-30) Conclusively, the role played by this organisation cannot be ignored. It continuously helps nations to recover from economic failures. It is lending surveillance police have benefited many and still proves to in years to come. In order to change the faulty image over the years, there must be some adjustments. This adjustment will enhance its role and make it productive as many presume it to

An RSA-Type OTP Generator

An RSA-Type OTP Generator An RSA-Type OTP Generator Aiswarya Vinayachandran,  Sivasankar M Abstract Simple and secure authentication protocols are in great demand due to the ever expanding use of internet for financial and message communications. Multifactor authentication, in particular 2Factor Authentication (2FA) is preferred to static passwords-only authentication. One Time Passwords (OTPs) play a vital role in the construction of 2FA protocols. In this paper, an efficient OTP generation algorithm, based on RSA scheme is discussed. Implementation and computational issues related to the algorithm are also discussed. Keywords: Authentication, RSA, One Time Password, LFSR, Primitive Element 1. Introduction These days, almost all our day to day activities, starting from buying vegetables to booking a movie ticket depend on internet. As highly private data is being communicated between the server and the client, secure protocols are required for protecting these transactions from attackers. Over the years, we realized that encryption methods alone are not sufficient to secure online transactions. Hence evolved the idea of sending some message each time personally to the user and prompting him to send back the message along with his/her password to complete the transaction. This provides a second layer of security and strength to the existing concept of static passwords. In this paper, we present a way to generate OTPs, based on RSA type exponentiation. This research paper is organised as: Section 2 explains authentication process; Section 3 briefly discusses the conventional way of OTP generation; Section 4 is the proposed algorithm; Section 5 discusses about the randomness in the generation of the OTPs; Section 6 analyses the operational complexity and security of the proposed algorithm; Section 7 gives some concluding remarks. 2. Authentication Authentication is the process of identifying the legitimate user [1]. The identity is proven by various cryptographic methods where the user has to enter some input to the system. This can range from simply entering a password to more complicated security mechanisms like biometrics, strings displayed by tokens, key encryptions. Based on this input, the system will identify and authenticate the person. After authentication, comes authorization, where the system identifies the various privileges available to the user. Only authorized users can get access to the data as not all the users will have the same privileges. Some users will be allowed to only read the data while some users will be allowed to read as well as modify it. 2.1. Message Authentication Message authentication is used to check if the received message has been tampered in the middle of the communication channel. Message authentication is used to protect the integrity of the message wherein the receiver should be notified if any bits in the message are modified, removed or extra bits are added during the communication. This is achieved by sending a message digest – usually hash of the message will be the digest – together with the message. If the receiver also is obtaining the same digest over the received message then he/she can be sure of the integrity of the message. 2.2. Entity Authentication Entity authentication is the process in which an entity (machine/human) in a distributed network will get belief on another entity (machine/human) based on a key already established between them. The idea is that the key is kept secret and only the two genuine communicating entities know the secret key. Machine authentication is achieved through the verification of digital credentials or digital certificates. Digital Credentials are like a machine provided ID and password or a digital certificated issued by a Certifying Authority (CA). It is like a digital passport that provides trusted identification. Digital Signature is a mathematical technique used to validate the authenticity of a digital document, software or a message. It is used to identify whether a communication is impersonalized. Human based authentication relies on at least one of the three key factors: something the user knows (a password or an answer to a security question), something the user possesses (an object for authentication, say smart card), and something the user is (behavioural or physiological characteristics of the individual say, finger print and retina scanning). 3. Conventional OTP Generators OTP is an authentication technique, which comes in the second layer of authentication protocols after static passwords. An OTP is valid only for a single transaction. Even if an attacker succeeds in decrypting the password of a user, he/she has to get the OTP generated to validate the transaction. Since OTP is based on randomness/collision resistance, it is very difficult to guess an OTP. Even if the attacker succeeds in acquiring an OTP, he may not be able to predict the next OTP. OTP generation is based on hashing algorithms. Hashing is an irreversible process, i.e. for an input we can get the output, but with the obtained output we cannot get back the input. Even if an attacker obtains many OTPs, it is of no use as he/she cannot find a pattern to guess the seed used to generate the OTPs. An OTP is valid for a limited time, generally two to fifteen minutes based on the web site’s restrictions. Also in online transactions, while entering an OTP, a user is allowed to make errors only a limited number of times, say twice or thrice, which again adds to its security. A most common way of generating a sequence of OTPs[2] is described in Algorithm 1. Algorithm 1: Conventional OTP Generation Algorithm Note that the weakness of the OTP mechanism lies on the channel used to send the OTP and the security of the device to which the OTP is send. It will be advisable to secure the device with some biometric credentials making it totally safe. 4 Proposed RSA type OTP Generating Algorithm After the invention of public key cryptography, encrypted communication reached the next level. In general, public key cryptography relies on some hard mathematical problems like Integer Factorisation Problem (IFP), Discrete Logarithm Problem (DLP) [3]. As our proposed OTP generation is based on RSA crypto-system, we briefly do a recap of RSA encryption [4]. 4.1 The RSA Algorithm The Rivest-Shamir-Adleman (RSA) algorithm is one of the popular and secure publickey encryption methods. The security of the algorithm relies on the fact that there is no efficient way to factor very large numbers. Using an encryption key (e, N), the algorithm is as follows: Choose two very large prime numbers, p and q; Set N equal to p.q. Choose any large integer, d, such that gcd(d, à ¯Ã‚ Ã‚ ¦(N) ) = 1. Find e such that e.d = 1 (mod à ¯Ã‚ Ã‚ ¦(N)); The encryption key (e,n) is made public. The decryption key d is kept private by the user. Represent the message as an integer between 0 and (N-1). Encrypt the message by raising it to the eth power mod n. The result is the cipher text C. To decrypt the cipher text message C, raise it to the power d mod n 4.2 Proposed OTP Generation Technique: Our proposed algorithm is based on RSA encryption/decryption process and is described in Algorithm 2 below. Algorithm 2: Proposed Algorithm The above procedure can be represented by a schematic diagram as in Fig.1. Fig. 1. Architecture of the Proposed Model 4.3. A Comment on the Selection of N and the Possible Number of OTPs Present day OTPs are of generally 6 digits in length. Hence they can range from 000000 to 999999, totalling to 10,00,000. This is so, as we have 10 choices (numbers 0 to 9) for every digit and hence 10.10.10.10.10.10 = 106 = 10,00,000. If we incorporate a module to condition that the first two most significant digits should be non zero, even then 9.9.10.10.10.10 = 8,10,000 OTPs are available. In our proposed algorithm, if we require 6 digit OTPs, we can select N close to the integer 999999. For example a choice of 991 . 997 = 988027 will be sufficient for our implementation. As the number of bits used to represent a 6 digit decimal number is approximately 20 bits (log2 999999 =19.93156713), we need to select a 20 bit RSA number for our algorithm. Note that, a 20 bit RSA crypto system can be easily broken by the present day computers when e and N are known outside. But here as the attacker does not know N and a, he/she cannot guess the next OTP, which is some random number that lies b etween 1 and N-1.The only information that the attacker can get is the current OTP, which is some 6 digit number. 5. Randomness in the Generation of the OTPs from ZN* Considering the demand for OTPs and the computational expenses of different exponential algorithms, it is advisable to follow a systematic approach for the selection of the random number aà ¯Ã†â€™Ã… ½ {1, 2,†¦ ,N–1} .We propose two convincing methods for the selection of a. 5.1. Linear Feedback Shift Registers (LFSRs): LFSR is a mechanism for generating random numbers based on the initial seed given to it. So if we start with a non-zero 20 bit string, the LFSR can generate all the other 220–1 20-bit strings. We refer to [5] for some basic facts about LFSR. An LFSR of length L consists of L stages 0,1 , †¦ , L-1, each capable of storing one bit and having one input and output and a clock which controls the movement of data. During each unit of time the following operations are performed; (i) the content of stage 0 is output and forms part of the output sequence; (ii) the content of stage i is moved to stage i 1 for each i, 1 ≠¤ i ≠¤ L – 1; (iii) the new content of stage L – 1 is the feedback bit s which is calculated by adding together modulo 2 the previous contents of a fixed subset of stages 0,1, †¦ , L – 1. We note that for an n-bit LFSR connectionpolynomials are available, where à ¯Ã‚ Ã‚ ¦ is the Euler’s totient function. So, for a six digit OTP, i.e. for a 20 bit string, we have = 24,000 choices. With each connection polynomial, we can generate all the 20-bit strings in different random ways. Since we have 24,000choices, we can assign a single connection polynomial for a single customer, and OTPs generated for each customer will be in entirely different pattern. 5.2 Primitive Roots: Another mechanism for generating 6 digit random numbers is by using the concept of primitive roots.We refer [6] for the concepts related to cyclic groups and generators/primitive elements..Let p be a prime number. Consider Zp*. Let gà ¯Ã†â€™Ã… ½ ZP*. As i vary from 0 to p–1, by computing gi mod p, we can generate all elements in Zp*. Here g is called the primitive root/generator of Zp*. As we have selected an RSA number N, which is not a prime number, to follow this kind of random number generation, we can N as a prime number very close to 999999. For example, N = p = 999983 will be sufficient. It is a known result that, if g is a primitive root, then gi is also a primitive root if gcd (i,à ¯Ã‚ Ã‚ ¦(p))=1. Hence we are available with à ¯Ã‚ Ã‚ ¦(à ¯Ã‚ Ã‚ ¦(p)) generators [6]. Hence if N = 999983 (a six digit prime), we have à ¯Ã‚ Ã‚ ¦(à ¯Ã‚ Ã‚ ¦(999983)) =493584 generators which means we have sufficiently large number of primitive roots at our disposal. 6. Computational Complexity and Security of the Proposed Algorithm The proposed algorithm is an RSA-type algorithm which uses modular exponentiation for its computation. The modular exponentiation operation generally consumes a considerable amount of time for large operands as it consists of a series of square-and-multiply operations under a modular value. For a particular user, e will be fixed. Hence the time complexity for ae (mod N) is O(log2e). As RSA is a widely implemented cryptosystem, improvements in modular exponentiation algorithms are evolving very frequently [7]. Though the proposed algorithm uses the concept of RSA with a 20-bit modular (where as the current standard is 256 to 512 bits), since a, e, N are not known publicly we achieve security through obscurity. 7. Conclusions and Future Works In this paper, we have proposed a new method to generate OTPs and discussed the possible ways of implementing it practically. There may exist other novel methods with less time complexity. Incorporating new methods we can design more efficient algorithm for generating OTPs. The possibility of generating alphanumeric OTPs will be also explored, in future. References [1]Bruce Schneier, â€Å"Applied Cryptographyâ€Å", Wiley Publications, 2002. [2] L.

Islam :: essays research papers

ISLAM   Ã‚  Ã‚  Ã‚  Ã‚   There has been much talk about Muslim beliefs and the Islam nation altogether. The basis of the religion is peaceful and understanding. While people twist the belief around to fit their own needs. It is based on the teachings of Muhammad. He was born in Mecca, which is the capital of Islamic belief.   Ã‚  Ã‚  Ã‚  Ã‚  Muhammad was born and raised in the city of Mecca. He grew up as a merchant and had a wife. He would wander around outside of the city by himself often. He wandered so much that he had no job but his wife believed in him so she supported him. One day he had a vision of the angel Gabriel. Gabriel told him that he was a prophet and he should spread the word of god. He went back to Mecca and told everyone what had happened and decided to teach everyone the way of God. No one believed him and he was ridiculed for his beliefs. So he decided to go on a trip which was called the â€Å"Hijra†. When he came back to Mecca he had many converts. Then the people of Mecca started to believe him and became converts themselves. This is the story of Muhammad and his teachings. All this and more were written down in the Muslim holy book, the â€Å"Koran†.   Ã‚  Ã‚  Ã‚  Ã‚  The five pillars are the five ways to be a good and decent Muslim. The first pillar is â€Å"Shahadah† which is to declare your belief by saying shahadah. Which means declaring god or Allah is almighty, and believing in the prophethood of Muhammad. The second pillar is â€Å"Salah† or prayer. Prayer must be done five times a day towards Mecca or the general direction of Mecca. The third pillar is â€Å"Zakah† or tax on the wealth. Everyone must give a percent of their earnings to the poor. The fourth pillar is â€Å"Sawm† which is fasting during the month of Ramadan. The fifth and last pillar is to at least once in their lives to â€Å"Hajj† or make a trip to Mecca when one is willing and able to.   Ã‚  Ã‚  Ã‚  Ã‚  There is so much trouble in the world because of guys who like to change the meaning of some things in religion when it is obvious what they mean.

Statement of Purpose Santosh G Vattam MS

Statement of purpose Santosh G Vattam MS, Embedded Systems (CIS), May 2012 Research Interest I am a Master of Science and Engineering student majoring in Embedded Systems from University of Pennsylvania, graduating in May 2012. I am interested in embedded systems modeling and model based code generation. This interest has developed thanks to my research project with Prof. Insup Lee as well as the Embedded and Cyber Physical Systems and the Principles of Embedded Computation courses I took at Penn with Prof. Insup Lee and Prof. Rajeev Alur respectively.The Embedded and CPS course involved modeling and implementation of a pacemaker, while the Principles of Embedded Computation course provided the much needed theoritical foundation for developing embedded system models and verifying and validating thus developed models. Research projects In Jan 2011, I started working on the Medical Device Dongle(MDD) Project with Prof. Insup Lee. The idea was to make patient monitoring, patient centric rather than device centric by developing a standards-based interface for medical device interoperability.We decided to use the existing device interoperability standard – IEEE11073-PHD with slight modications. I implemented the rst prototype of the IEEE11073 Manager and Agent state machines. We later encountered the problem of providing a medium for using the services of the MDD and thus we designed and implemented an interface to sit on top of the MDD. We have since presented our work at the Wireless Health Conference 2011, San Diego, CA and at Embedded Software Week Android competition, Taipei, Taiwan. We shall also be presenting at the International Health Informatics Symposium, Miami, FL in Jan 2012.Prior to this, I have worked on the Coverage Analysis of RTEMS(Real Time Executive for Multiprocessor Systems) as part of Google Summer of Code 2009 and mentored another student in 2010 for the same project. This project was my rst step into the embedded world. I wrote tes t cases to validate that every single line of object code generated was executed. I worked on the RTEMS-core codebase and in 2010 I mentored a student to work on the extended codebase. Research focus I would like to focus my research on model based code generation and validating the conformation of code to the model on which it was based.This is a problem that I have come across while working on the MDD project. We have based our design on the IEEE11073 architecture but there are no open implementations of it through which we can verify our implementation. There are certain validation tools but these just analyze the packet structure of the 11073 packets but not the ow of these packets within the network of devices. I am partly tackling this problem through my Masters thesis by writing test cases to validate the exchange of the right packets. This method, however, does not provide insight into the internal state ow of the code. I would like to study, n depth, the ways of validating code to the state model. I believe that by pursuing a PhD I shall not only gain the necessary skill set to tackle this problem, but also the insight of looking at unstructured data and obtaining structured information from it. Prof Insup Lee and his team at the PRECISE Center work on model based design and validation in the medical device domain. I have been working with Prof. Insup Lee and his team for close to a year now on the MDD project. I believe that the environment and the expertise at the PRECISE Center will provide me with the encouragement and the academic stimulus to excel at my research.

This interest has developed thanks to my research project with Prof. Insup Lee as well as the Embedded and Cyber Physical Systems and the Principles of Embedded Computation courses I took at Penn with Prof. Insup Lee and Prof. Rajeev Alur respectively.The Embedded and CPS course involved modeling and implementation of a pacemaker, while the Principles of Embedded Computation course provided the much needed theoritical foundation for developing embedded system models and verifying and validating thus developed models. Research projects In Jan 2011, I started working on the Medical Device Dongle(MDD) Project with Prof. Insup Lee. The idea was to make patient monitoring, patient centric rather than device centric by developing a standards-based interface for medical device interoperability.We decided to use the existing device interoperability standard – IEEE11073-PHD with slight modications. I implemented the rst prototype of the IEEE11073 Manager and Agent state machines. We later encountered the problem of providing a medium for using the services of the MDD and thus we designed and implemented an interface to sit on top of the MDD. We have since presented our work at the Wireless Health Conference 2011, San Diego, CA and at Embedded Software Week Android competition, Taipei, Taiwan. We shall also be presenting at the International Health Informatics Symposium, Miami, FL in Jan 2012.Prior to this, I have worked on the Coverage Analysis of RTEMS(Real Time Executive for Multiprocessor Systems) as part of Google Summer of Code 2009 and mentored another student in 2010 for the same project. This project was my rst step into the embedded world. I wrote tes t cases to validate that every single line of object code generated was executed. I worked on the RTEMS-core codebase and in 2010 I mentored a student to work on the extended codebase. Research focus I would like to focus my research on model based code generation and validating the conformation of code to the model on which it was based.This is a problem that I have come across while working on the MDD project. We have based our design on the IEEE11073 architecture but there are no open implementations of it through which we can verify our implementation. There are certain validation tools but these just analyze the packet structure of the 11073 packets but not the ow of these packets within the network of devices. I am partly tackling this problem through my Masters thesis by writing test cases to validate the exchange of the right packets. This method, however, does not provide insight into the internal state ow of the code. I would like to study, n depth, the ways of validating code to the state model. I believe that by pursuing a PhD I shall not only gain the necessary skill set to tackle this problem, but also the insight of looking at unstructured data and obtaining structured information from it. Prof Insup Lee and his team at the PRECISE Center work on model based design and validation in the medical device domain. I have been working with Prof. Insup Lee and his team for close to a year now on the MDD project. I believe that the environment and the expertise at the PRECISE Center will provide me with the encouragement and the academic stimulus to excel at my research.

Free Essays on Favorite Teacher

My Favorite Teacher As a student growing up I had a lot of teachers like everyone else, but one teacher who really stimulated me was Mrs. Sandra Gregg. Mrs. Gregg is still today an elementary teacher at Brunson-Dargan Elementary School. There are many reasons why she stimulated me to become a teacher. The most important qualities she possesses are: she shows dedication through her students, patience through her teaching abilities, devotion through her work and most importantly is her love for all her students. Mrs. Gregg is an excellent role model for many children because she has many unique qualities that a lot of teachers lack today. Mrs. Gregg showed an enormous amount of patience to her students. If a student did not do their homework she never got frustrated instead she had many useful techniques to motivate her students to apply themselves. The way she approached a student who did not do their homework was by sitting next to them during class and by spending more time one on one with that student. There was never a wrong answer in her class and she encouraged her students to learn by reading stories, writing letters to each other and by drawing pictures. Mrs. Gregg always gave her students a hug just for showing an effort in her class, which showed me her love for us. The final yet greatest quality Mrs. Gregg possesses is that through her work she demonstrates her devotion to teaching. Anyone who knows her can see how committed she is to her work. She is one of those individuals who are gifted with the job that they do because she brings out the best qualities in her students. She inspires her students to be motivated to learn and to belief in themselves. In my opinion the greatest role model as a teacher is one who can achieve all these qualities and change lives like Mrs. Gregg has done already. The reason why I want to become a teacher is to help students be motivated to learn. I also want to make a difference in...

Finite Element Method in Computer Simulation Outline

Finite Element Method in Computer Simulation - Outline Example In this scenario, some of the industrial uses and applications of FEA can comprise effect or crash analysis of automobiles, structural analysis of bridges and buildings, electromagnetic analysis of AC and DC motors, aerodynamic analysis of airplanes and airfoils, injection molding simulation of plastic components, fluid flow investigation in channels and pipes and heat transfer through housing and commercial places and buildings. In addition, FEA uses certain physical principles that guide it regarding the actions of these physical systems. In view of the fact that biological systems also comply with the similar basic physical principles, hence the FEA can also be used to forecast the physical reaction of biological systems to recognized loading circumstances (Roylance, 2001; BIO-Mesh, 2012). The first principle is known as preprocessing which allows the user to build a framework of the component of a physical system that has to be tested. Additionally, at this step, the geometry is classified into several separate subparts, which are linked with each other at isolated places acknowledged as nodes. In addition, these frameworks are believed to be very time-consuming to put in order, as well as viable codes oppose one another to get the most easy to use graphical preprocessor to support in this somewhat tiresome task. In some cases, these preprocessors can spread over the surface a mesh on a preexisting CAD, with the intention that element analysis can be completed handily as an element of the automated drafting and design process. In this scenario, the process that is followed by the FEA modeler in order to communicate this information to the FEA software is known as "boundary conditions." In addition, boundary conditions notify the FEA software how loading would be chal lenged by rotations of definite nodes and restricted displacements (Roylance, 2001; BIO-Mesh, 2012; Starns, 2010).

Cultural dimension - Assignment Example The application of in-depth questions in the semi-structured questionnaires drew the study towards the acquisition of the required outcomes since the interviewees were not coerced to answer in a particular controlled manner. Therefore, the research process established the prevalence of a civilised culture in the Japanese society before the documentation of the Austrian culture. 2.1 Two students from Japan and Austria were selected for the interview, which involved the use of open-end questionnaires. The students were chosen because they possessed the most dominant and influential cultures in the history of civilization. With the use of open-end questions and semi-structured questionnaires, they were asked many questions; hence, they stimulated the opportunity of acquiring a wide range of answers in the absence of research bias. This was done by using the most important issues about their cultures. In this questionnaire, the participants were enquired to rate the most significant and particular issues. These questions helped in understanding concepts that hold significance to the respondents, and allowed critical decisions about the countries’ cultures. The two students answered the questions in accordance to their societal perspectives; hence, the results influenced the study to establish that the Japanese and Austrian societies were embracing democratic practices in leadership, with the common objective being the improvement of the lifestyles and economic progression. 2.2 The  next section represents an analytical approach that evaluates the information gathered during the study. Since the application of the qualitative method of survey enhanced the level of participation among the chosen sample population, it was noted that there were many differences and similarities between the Japanese and Austrian cultures. The Japanese culture is exceedingly older than the Austrian culture
