TL;DR: A variety of robotic and mechatronic system applications that deviate from traditional rehabilitation uses, augmenting or replacing lost functional abilities, to applications which use these systems as therapeutic tools serving as part of the rehabilitation, vocational therapy, and educational process as discussed by the authors.
Abstract: Presents and discusses a variety of robotic and mechatronic system applications that deviate from traditional rehabilitation uses, augmenting or replacing lost functional abilities, to applications which use these systems as therapeutic tools serving as part of the rehabilitation, vocational therapy, and educational process. These applications will include those systems designed and developed by the Enabling Technologies Laboratory at Wayne State University, as well as other organizations. Themes are emerging from the experiences gained through these diverse applications. Robotic/mechatronic systems promote active participation by the client. They are finding applications where consistent, repeatable manipulative operations are required for extended periods of time. The roles played by therapists, teachers, and service providers change as the role of the technology changes. Service providers are freed from mundane nontherapeutic or noneducational activities, and consequently are able to focus more fully on the client and the therapeutic or educational tasks. The systems have characteristics that improve their cost/effectiveness. For example, therapists or service providers can often leverage their time and attention by accomplishing multiple objectives and/or serving multiple clients with a given therapeutic or educational task. The systems typically perform multiple functions. Therapeutic activity is generally billable, and therefore the technology represents a revenue source. Since the technology is used by a number of clients, its cost can, be amortized over this client base. Lastly, clients tend to enjoy working with the technology. Each application is different, but in general, the systems are providing clients the positive effects of competent participation in a task or activity. These applications present system uses that go beyond augmentation and replacement of lost functional abilities and, as such, are expanding the popular model, or paradigm, regarding robotic and mechatronic system applications. >

TL;DR: It is argued that it would be more accurate to call computer science a new species of engineering, and agrees with Hartmanis that attempts to distinguish computer science from computer engineering are futile.
Abstract: Hartmanis calls computer science “a new species among the sciences,” whose science and engineering aspects are particularly close. I have argued that it would be more accurate to call computer science a new species of engineering [Loui 1987]. Let me summarize the argument. The goal of engineering is the production of useful things, economically, for the benefit of society. These things include artifacts such as steel bridges, electronic circuits, automobile engines, and jet aircraft. Engineers also design manufacturing and chemical processes. A process is similar to a computational algorithm, which is a method for processing information. (Whether a process or an algorithm is patentable is a legalistic matter,) Like traditional engineering disciplines, computer science is concerned with producing useful things such as microprocessors, software, and databases. Furthermore, economic constraints require engineers to seek efficient solutions to technical problems in the design and manufacture of products. An emphasis on efficiency is also a distinguishing characteristic of computer science. Unlike other creative arts, engineering disciplines have a scientific basis—the engineering sciences: statics, dynamics, mechanics of solids, thermodynamics, fluid mechanics, and so on. Since World War II, all engineering disciplines have matured by incorporating their scientific foundations. The scientific fundamentals of computer science include Boolean algebra, computability theory, and automata and formal languages. The fundamental concepts and principles of computer science are rooted not in the physical phenomena of force, heat, and electricity, but in mathematics. Computer science is therefore a new kind of engineering. I agree with Hartmanis that attempts to distinguish computer science from computer engineering are futile. One conventional view—espoused by computer engineers-is that computer science comprises only theory and computer engineering comprises everything else. But excluding theory of computation from computer engineering would be as inconceivable as excluding circuit theory, linear system theory, communication theory, control theory, electromagnetic theory, and semiconductor theory from modern electrical engineering. A fortiori, the role of automata theory in computer science is analogous to the role of linear system theory in electrical engineering: the theories provide effective models for the design, analysis, and understanding of programs and circuits.

TL;DR: In this article, the principle of virtual work is applied to electromechanical systems as the foundation of a unifying concept for modelling mechatronical systems, which yields an analogous form to the central equation of mechanics which is valid for holonomic and nonholonomic systems.
Abstract: The principle of virtual work is applied to electromechanical systems as the foundation of a unifying concept for modelling mechatronical systems. After the presentation of an important result in the field of mechanics, the expansion of the principle on electrical networks and electromechanical systems is shown. The use of the principle of virtual work in the domain of electromechanics yields an analogous form to the central equation of mechanics which is valid for holonomic and nonholonomic systems. The electrotechnical part of the system is confined to networks. The derivation of the mathematical model is demonstrated on the example of a simple electromechanical oscillation circuit. In addition, the physical systems are separately treated, taking into account the explicit constraints on the basis of the Lagrangian multiplier method.

TL;DR: This paper describes how a generic framework for storing and retrieving public and private model data is needed based on a differentiation between three different levels of abstraction, which are defined as engineering components, conceptual descriptions in terms of physical processes, and mathematical relations.
Abstract: The availability of reusable and sharable models of physical systems will be a major advance in Computer Aided Engineering. Therefore, a generic framework for storing and retrieving public and private model data is needed. Our thesis is that such a framework must be based on a differentiation between three different levels of abstraction, which we define as engineering components, conceptual descriptions in terms of physical processes, and mathematical relations. Our approach is centered around the bond graph language, which provides the conceptual link between components and mathematical relations, a.o., in the field of mechatronics. When constructing a model, a system is decomposed down to an appropriate level of granularity. Each component is associated with one of a number of alternative conceptual descriptions (bond graphs), one of which is to be selected. Concepts (i.e. bond graph elements) in turn are further specified by selection from a number of alternative mathematical relationships. Moreover, previously assembled models based on the generic building blocks can also be stored in the library. In this way, models with different levels of detail and validation status can be assembled. In this paper we describe how this framework supports the modeling process. An example session shows the route a modeler might follow to assemble the model of his/her needs.

TL;DR: The current status of CAD applications and industrialization in China is concisely described in this paper, where the potentiality of an extensive market of CAD application is analyzed. And the models of developing CAD application and industrialisation in China are related.
Abstract: The current status of CAD applications and industrialization in China is concisely described in the paper Then, the potentiality of an extensive market of CAD applications is analyzed. Finally, models of developing CAD applications and industrialization in China are related. THE CURRENT STATUS OF CAD APPLICATIONS AND INDUSTRIALIZATION IN CHINA 1.1 Chinese government supports the development of CAD applications and industrialization Computer aided design is a critical high technology to accomplish design automation, expedite the transformation from scientific and technological achievements to production forces, and to accelerate national economy development and four modernizations. The application of CAD technology is not only the main aspect of reformation of traditional industrial technologies but also an important leverage to raise product and engineering design to a higher level, reduce cost, shorten design cycle, and to improve the labor productivity, as well a significant requirement for enterprises to enhance their competitive power and adaptive faculty in market. The level of applying CAD technology is also one of the major marks indicating the level of national industrial technologies. Pan One Keynote Papers In order to impel the development of CAD applications and industrialization, Chinese government has been including the development of CAD in the National Science and Technology Key Projects and Torch Program for a long time, encouraging enterprises to adopt CAD technology and carrying out preferential policies for them. The national developing plan of CAD applications has been formulated, in addition, a coordinating and directing group of CAD application engineering, which was sponsored by the National Science Committee and participated by eight state ministries and committees, has been established. 1.2 The current status of CAD applications and industrialization in China Starting in 1960s and passing through its developing period mainly in 1970s and 1980s, CAD in China is now beginning its preliminary applications in engineering designs and product designs in diverse fields such as machinery, electron, aviation, aerospace, architecture, shipbuilding, light industry, textile industry, and so on, and has obtained remarkable technical and economic benefits. For example, in National Designing Institutes, more than 90 percent of calculation, 50 percent of project design and 30 percent of drawings were finished by using CAD technology. It raised working efficiency as 3 to 10 times as before, and saved as much as 2 percent of capital construction investment. As a result, 2 billion yuan of engineering investment has been cut down on only during the 7th. five-year plan period. According to the results of our sample survey, the installation situation of computers and CAD systems in 1992 is listed as follows.

Abstract: Microprocessors are fast becoming essential components for the design of communication oriented products. The design of such products is illustrated by projects drawn from microprocessor design courses taught at the George Woodruff School of Mechanical Engineering at the Georgia Institute of Technology, USA. The courses' emphasis is on an integrated, multidisciplinary, concurrent design philosophy: group oriented working and communication skills; independent investigations of new material; and a viewpoint of practical, hands-on instruction. The projects emphasize a concurrent design philosophy where hardware and software design are simultaneously developed. The projects also emphasize low-cost components and user-friendly interfaces suitable for consumer product design. >
TL;DR: The state of the art in research and technology has clearly fallen far behind the requirements of industrial, commercial, and government complex computer systems.
Abstract: We define the engineering of complex computer systems as all activities pertinent to specifying, designing, prototyping, building, testing, operating, maintaining, and evolving complex computer systems. While in the past, relatively noncomplex traditional systems sufficed for most computer control applications, the new and emerging demands of applications and the evolution of computer architectures and networks now essentially force systems to be complex, given our current understanding of how to engineer these systems. Complex computer systems are found in almost every industry. These include industrial process control, aerospace and defence, transportation and communications, energy and utilities, medicine and health, commercial data processing, and others. Unfortunately, the state of the art in research and technology has clearly fallen far behind the requirements of industrial, commercial, and government complex computer systems. >
