...“Reverse engineering is the process of extracting the knowledge or design blueprints from anything man-made. Reverse engineering is usually conducted to obtain missing knowledge, ideas, and design philosophy when such information is unavailable. In some cases, the information is owned by someone who isn't willing to share them. In other cases, the information has been lost or destroyed” (Eilam, 2005). The advantages and disadvantages of reverse engineering are as follows; Advantages * It helps in the evolving of existing computing systems. * “You can change a program's structure and thus directly affect its logical flow. Technically this activity is called patching, because it involves placing new code patches (in a seamless manner) over the original code” (Hoglund & McGraw, 2004). * As a learning tool * As a way to make new compatible products that are cheaper than what's currently on the market. (Schwartz, 2001) * For making software interoperate more effectively or to bridge different operating systems or databases. * To uncover the uncoordinated features of commercial products. Disadvantages * “Manually translated source code often retains the style and flavour of the original implementation”. (Byrne, 1991) * “The most commonly recognized problem with literal translation is summed up as: garbage in, garbage out. If the existing system is not well-structured, both in terms of its architecture and control-flow, then the resulting system will be of the same...

...Assignment 1 Exploring Reverse Engineering Reverse engineering can be viewed as the process of analyzing a system to: 1. Identify the system's components and their interrelationships 2. Create representations of the system in another form or a higher level of abstraction 3. Create the physical representation of that system. Reverse engineering is very common in such diverse fields as software engineering, entertainment, automotive, consumer products, microchips, chemicals, electronics, and mechanical designs. For example, when a new machine comes to market, competing manufacturers may buy one machine and disassemble it to learn how it was built and how it works. A chemical company may use reverse engineering to defeat a patent on a competitor's manufacturing process. In civil engineering, bridge and building designs are copied from past successes so there will be less chance of catastrophic failure. In software engineering, good source code is often a variation of other good source code. Reverse engineering enables the duplication of an existing part by capturing the component's physical dimensions, features, and material properties. Before attempting reverse engineering, a well-planned life-cycle analysis and cost/benefit analysis should be conducted to justify the reverse engineering projects. Reverse engineering is typically cost effective only if the items to be reverse engineered reflect a high investment or will be reproduced in large quantities. Reverse engineering...

...[pic] Reverse Engineering a New Trend in Manufacturing [pic] Authors T.Dhamotharakumar* N.S.Ramesh* dhamotharan007@gmail.com nsrmechanical@gmail.com * Under graduate Student, K.S.R. College of Engineering, Tiruchengode Department of Mechanical Engineering [pic] Abstract With the significant capital investment in new equipment being placed into out years, more systems need to be maintained in their present condition for longer periods of time. There are often gaps in the technical support information needed to maintain a system built from older designs using outmoded or updated techniques or materials. In some situations, designers give a shape to their ideas by using clay, plaster, wood, or foam rubber, but a CAD model is needed to enable the manufacturing of the part. As products become more organic in shape, designing in CAD may be challenging or impossible. There is no guarantee that the CAD model will be acceptably close to the sculpted model. Reverse engineering provides a solution to this problem because the physical model is the source of information for the CAD model. This is also referred to as the part-to-CAD process. "Reverse Engineering is the process of taking a finished product and reconstructing design data in a format from which new parts or molds can be produced."-The Society of Manufacturing Engineers Key Words: Reverse Engineering, CAD, Modeling and manufacturing. ...

...technologies are that it has the ability to grab internet servers that web services and tools such as internet apps or anything that can produce these services. One profitable feature of .NET is its ASP.net technologies that allows for the making of additional websites and net services that exist on the .NET infrastructure, (Getdotnu.com, 2004-06). Another powerful advantage of .NET technology is the ASP feature is that it creates construction sites, services and applications and does not require as much coding as the older coding in the beginning. A disadvantage of the use of .NET is its lack of support on several platforms or multiplatform to be exact. Another disadvantage is which can be very detrimental is that .NET can be reverse engineered meaning the code can be reversed and basically the code copied just rewritten.

...intelligent man that created the basis of our pc operating systems today. The software that CP/M / Digital Research created is great and all should know about it Without it we may not have gotten as far as we have with technology today. This article plus the “gray” note on page 14 tells a story about a man who took great interest in his work. When IBM tried to sell him short or give him an offer to work for them he told them that he didn’t like the offer and he turned them down. Well this gave Microsoft a chance to come in and take the deal, but what’s funny about that is Microsoft went and reverse engineered the Digital Research tech and created a copy of it and sold it to IBM. Although at this time no one was charged for any illegal acts (maybe because it was uncommon to be able to do what Microsoft had done). I do feel two different ways about this process, see Microsoft had a genius idea to reverse engineer the software, but at a price of Dr. Kildall’s company Digital Research’s fall . The...

...Reverse engineering involves taking something apart to see how it works. The advantages are you can learn the kind of system functions a target program is using. You can learn the files the target program accesses. You can learn the protocols the target software uses and how it communicates with other parts of the target network. The most powerful advantage to reversing is that you can change a program's structure and thus directly affect its logical flow. The disadvantages would be by enabling competitors to create competing devices, the possibility of reverse engineering might decrease the incentive for technology creators to develop new products, and reducing the manufacturer’s control over consumer uses for the product might have the same effect.

...Research Assignment 3: Exploring Reverse Engineering • What is reverse engineering? Reverse engineering is the general process of analyzing a technology specifically to ascertain how it was designed or how it operates. This kind of inquiry engages individuals in a constructive learning process about the operation of systems and products. Reverse engineering as a method is not confined to any particular purpose, but is often an important part of the scientific method and technological development. The process of taking something apart and revealing the way in which it works is often an effective way to learn how to build a technology or make improvements to it. When reverse engineering software, researchers are able to examine the strength of systems and identify their weaknesses in terms of performance, security, and interoperability. The reverse engineering process allows researchers to understand both how a program works and also what aspects of the program contribute to its not working. • What are the advantages and disadvantages of using reverse engineering to discover the logics of a software program? Reverse engineering in software is reversing a program's machine code back into it's original source code. The advantages to using this technique is that one can repair certain bugs, see how a program operates, and improve the operation of the program. The disadvantage is that certain other bugs may be introduced during this process. ...

...Unit 3 Research Assignment 1 PT1420 Exploring Reverse Engineering Reverse engineering in computer programming is a technique used to analyze software in order to identify and understand the parts it’s composed of. The usual reasons for reverse engineering a piece of software are to recreate the program, to build something similar to it, to exploit its weaknesses or strengthen its defense. A reverse engineering advantage could be that one can repair certain bugs, see how a program operates and improve the operation of the program. You can learn the kind of system functions a target program is using. You can learn the files the target program accesses. You can learn the protocols the target software uses and how it communicates with other parts of the target network.

...to this new culinary movement range from enthusiasm, buoyant with foam sauces and bubbling liquid nitrogen, to perplexed looks or mutterings of disapproval. Some people’s understanding about molecular gastronomy appears to be free-form dots scattered over the culinary map, perhaps it’s time to connect those dots. Molecular gastronomy can be defined as the fusion of food science and culinary arts. New technologies and natural texturing agents can now be used to deconstruct any dishes and cocktails, enabling one to serve mojito bubbles and martini bites, as well as balsamic vinegar pearls and chocolate spaghettis. Molecular Gastronomy has become the name of the scientific discipline co-created by Nicholas Kurti and Herve This, based on exploring the science behind traditional cooking methods. Herve This identified five goals of this new science: “(1) to collect and investigate old wives’ tales about cooking; (2) to model and scrutinize existing recipes; (3) to introduce new tools, products, and methods to cooking; (4) to invent new dishes using knowledge from the previous three aims; and (5) to use the appeal of food to promote science.” Molecular gastronomy was born in 1988, when two scientists, Nicholas Kurti and Herve This, decided to investigate culinary transforma¬tions. This described molecular and physical gastronomy as the physics and chemistry behind the preparation of a dish. In 1992, both scientists organized the first International Workshop on Molecular and Physical...

Linton a,*, Robert Klassen b, Vaidyanathan Jayaraman c a Paul Desmarais Professor in the Management of Technological Enterprises, School of Management, University of Ottawa, Ottawa, Ont. K1N 6N5, Canada b Ivey School of Management, University of Western Ontario, London, Ont., Canada c Department of Management, School of Business, University of Miami, Coral Gables, FL, USA Abstract Consideration is given to the convergence of supply chains and sustainability. In doing so, the focus on environmental management and operations is moved from local optimization of environmental factors to consideration of the entire supply chain during the production, consumption, customer service and post-disposal disposition of products. This is a critical and timely topic that captures increasing concerns over sustainability, whether driven by current legislation, public interest, or competitive opportunity. As such, sustainable development is a rich area for academic research that is still in its infancy and has the potential to affect future government policy, current production operations, and identify new business models. This paper provides a background to better understand current trends in this multidisciplinary field that intersect with operations management, and the research opportunities and challenges it...
