Abstract The different phases of garment manufacturing currently requires approximately three times as much time to bring the garment to market as the actual life span of the garment. The paper shows that to compensate for the results of the greater effort in the product preparation and to be able to react more effectively and flexibly to the latest fashion movements, the use of advanced Computer Aided Design (CAD) and Computer Aided Manufacturing, (CAM) solutions has become essential. This paper gives a brief overview of three companies specializing in developing 3D CAD software and hardware for the textile design industry - Gerber Technology, Lectra and PAD System Technologies.
From the Paper "In addition to 3D CAD systems designed to model fabric behavior and characteristics, software designed to scan and store 3-dimensional body measurements of actual models are part of the process for achieving design goals quickly. By storing body dimensions in the software's database, the designer can see how differing dimensions will affect the drape, weft and warp direction of fabrics in 3D. Finally, software designed to measure people in real time can allow for highly customized clothing specifications to be manufactured in the fraction of the time as has been traditionally possible."
Abstract This paper presents CAD, or coronary artery disease. The paper begins with an overview of CAD, including statistical data. Next, the paper explores the etiology of disease.

Abstract This paper reviews the impact of Computer Aided Design (CAD) on aviation safety. In particular the paper looks at how CAD has incorporated Human Factors Principles, that is to say an appreciation of the kind of people who will be using the technology, into the design making process.
From the Paper "There can be little question that few occupations demand more of their practitioners than do the various branches of aviation. To begin with, any aircraft - be it a jetliner, a fighter jet, or even a small private airplane - is an extremely sophisticated piece of machinery. More specifically, they travel at high rates of speed, they can be (at least in the case of commercial aircraft) very unwieldy and cumbersome and their malfunction and/or mistreatment can result in almost certain death; quite simply, they are not items with which to be trifled. Adding to the dangers posed by these aircraft is the fact that their pilots - at least in military and/or commercial contexts - are expected to do more, and to do it more quickly, than ever before."

From the Paper "Prototypes have long been a valuable part of manufacturing and machining processes. The simplest form of a prototype provides a non-working model of the finished product that allows possible design flaws to be noted and corrected prior to investing in an entire production run. Materials, dimensions, production difficulties and other aspects of a product can be evaluated in a "real-world" environment prior to moving ahead with a new product. The benefits of prototyping are that companies are able to evaluate products without necessarily committing to them, and designs can be optimized in small lots so that resources are not spent inefficiently ("The Solid," 2001)."

Abstract This paper examines the impact of newly integrated computer-aided design (CAD) systems in improving safety factors in the aviation industry by looking at where it can be improved. The paper looks at how CAD has incorporated the human factors principle - that is, the type of people who use the technology - into the design-making process. The paper explains that on the whole, CAD technology is an enormous improvement over older aviation design because it allows designers to visualize situations in three-dimensionality throughout the design process. CAD can provide a very good visualization overview of human interaction with the product (in this case, the pilot user interface of a cockpit). The paper also explains that CAD technology is an excellent tool for designing pilot user interfaces because it saves time and money, and CAD technology is infinitely superior to the research tools that preceded it, because it allows designers to see hypothetical human reactions to environmental stimuli in three dimension. The paper then points out that, CAD is not so intuitive that it can anticipate every conceivable human reaction that might result from a particular situation. The writer believes, therefore, that there remains a need for live testing with actual people.

From the Paper "Whenever a study examines new technology, there will be some limitations. Today, CAD technology offers the promise of creating cockpit devices that will accommodate pilots of every skill level and idiosyncrasy; although a CAD-based ergonomic analysis program allows for the creation of accurate, 3-D human models, it seems extremely unlikely that any computer program can truly simulate the enormous range of abnormal responses that can be expected of different human beings. Therefore, human subjects are desirable in assessing the effectiveness of different products within the cockpit - and finding an appropriate sample group is not easy. It is extremely difficult to assemble a representative sampling of different pilots (in simulated conditions, of course) with the intent of measuring the capability of CAD in avoiding in-air tragedies."

From the Paper "Thus the implementation process actually required certain changes to be made within the workplace, but those areas of change were not focused on properly. Some of the important changes, as spotted by Sommerville (2004) in his case study, are: Re-configuring the control room, using only system proposed resource allocators and separate allocators for different call sources. These changes would have paved theway for an efficient implementation, but the changes were not well communicated and hence the new practices seem to have come as a surprise to most of the staff. The PMBOK guide (2000), when discussing communications planning, states: "Communication planning involves determining the information and communications needs of the stake holders: who needs what information, when they will need it, how it will be given to them and by whom"(p.119)."
Abstract Visionary Design Systems (VDS) is a highly successful developer of CAD (computer aided design) software that is sold in conjunction with the company's position as a value-added reseller of Hewlett-Packard CAD hardware and software. The paper shows that VDS has expanded its operations to include multiple remote offices staffed by a sales representative and at least one application engineer (AE). In addition, the company has a progressive approach toward its management, with the result that all employees are stockholders in the organization (which is currently privately held) and all employees receive both bonuses and commissions on their efforts related to selling the core product (CAD). The paper shows that, at this point, the company is intent on selling Product Data Management (PDM), which is an adjunct product to the CAD products and which has received strong support in the industry. However, the company is disappointed in the performance of its PDM specialist, and the specialist is disappointed in the internal support he has received from the company. This research considers the company's current position with regard to PDM and alternatives which might help the company achieve its long-term goals and objectives.
From the Paper "VDS could purchase a PDM company (or the PDM organization from another company) and integrate it into the organization. This would require a considerable amount of cash outlay up front, but would save VDS the problem of having to "invent" the PDM organization within its own company. The problems associated with changing the corporate culture would not be avoided, since the new employees would have to be integrated into the culture of VDS, but the focus would be on bringing those employees into the VDS culture rather than changing the culture of VDS so radically that PDM could succeed."
Abstract The paper explains that computer aided design (CAD) involves the application of computer technology to the design of the cockpit so that it is more ergonomic and more sensitive to the characteristics of different pilots. The paper relates that, on the whole, CAD technology is an enormous improvement on older aviation design because it allows designers to visualize situations in three-dimensionality throughout the design process. The paper discusses the CAD-based ergonomic analysis programs that allow researchers to create accurate 3-D human models that measure the impact of ergonomics on the safety and reliability of products, equipment and facilities. The paper includes graphs, tables and illustrations.

From the Paper "Aircraft accidents that lead to loss of lives receive the highest level of attention in the aviation industry. There are many different causes for aircraft accidents that occur on an everyday basis in the aviation industry, which range from pilot errors to mechanical challenges. Some of those errors are minor, but others can have devastating effects. Pilot errors can be minimized by utilizing adequate tools and various analyses. Human factors are one of the methods that would improve safety. The term "human factors" has grown drastically, and has become more popular as the commercial aviation industry realized that human errors underlies most aviation accidents and incidents, rather than mechanical failure (Greaber 1999)."

From the Paper "Introduction
The image of the dedicated drafting professional working over a large drawing board with a mechanical pencil, straight edge and various sizes of plastic triangles is quickly fading from the American workplace. Today's drafters are likely to be sitting in a well-lit office in front of a computer terminal using not a pencil, but a computer mouse to construct a drawing. With a click of the mouse, drawings can be shown in three dimensions, rotated, animated, and viewed from many different angles. Through such modeling, designers and engineers are able to spot problems which could not be readily seen in two dimensions. Although computer aided drafting (CAD) has many advantageous over manual drafting, there are still some environments in which manual drafting continues to be used. This research examines manual..."

From the Paper "Introduction
Companies rely on having efficient and rapid development cycles in order to remain profitable. The time it takes to bring a product to market starts when the idea for the product is first considered, and includes the development and production of the first unit. In the service sector, time-to-market can be short and require little more than hiring the right individuals to provide the service. In manufacturing, time-to-market can be considerably longer as companies encounter problems with suppliers or their own designs along the way. When machining and casting is involved, the design process can be both time.consuming and expensive as various designs have to be reworked and retooled before they meet the expectations and demands of the business. Computer-assisted manufacturing (CAM) and computer-assisted..."
Abstract An increasingly common phrase being bandied about today is ?reverse engineering.? The U.S. Supreme Court has defined reverse engineering as starting with the known product and working backward to divine the process that aided in its development or manufacture. This paper provides a comprehensive examination of precisely what reverse engineering is, how it is being used today, and what the implications of the technique may be for the future. A summary of the research is provided in the conclusion.
From the Paper "According to McGonagle and Vella (1996), in reverse engineering, a company takes apart a product and examines how it was assembled, what it cost, and what the entire package and its components tell us about the competition and its activities. "Typically, the customers of reverse engineering are those in product development and engineering. The time horizon is always retrospective, since the company is looking at what has already been done, and the targets are competitors, direct and sometimes indirect" (McGonagle & Vella, 1996, p. 17)."
