The trend of large-scale development of design industry requires efficient and full use of the rich design resources in the distributed multi-disciplinary resource environment. However, the designers are susceptible to many subjective and objective impacts, like knowledge structure, computing capability, geographic position, and administrative division. These impacts make the usage of design resources unstable and inefficient. Therefore, this paper proposed a computer-assisted automatic conceptual design system (CACDS). This system assumes that the design resources in the distributed multi-disciplinary resource environment exist in the form of functional elements with the same format, so that, the geographic, administrative, and disciplinary barriers in the design process can be broken, and the design resources can be fully used. CACDS is based on a group of basic concepts and their representations, its core is a functional solution generating algorithm, which is used to automatically generate functional solutions. As the result of the conceptual design, these functional solutions are also the starting point of the following detail design phase. Finally, a lighting system for underground greenhouse is designed as an illustrative case to validate the feasibility of the proposed CACDS.

This paper discusses a computer-assisted design system that makes use of multiple windowing, and its implementation f or typeface design. The system assigns each of five levels in the design task to a separate window, and allows the effect of changes made at any level to be seen in the other windows. The system is designed to be acceptable to designers and to avoid inhibiting their creativity.

The primary objective of this article is to discuss the role of Computer Assisted Instruction (CAI) at the undergraduate level via a survey of related literature and specific applications. CAI shares many features with other instructional modes, such as traditional classrooms and programmed instruction (PI). Many characteristics of learners affect their ability to learn and acquire new knowledge. An individual's subject-specific knowledge and general knowledge both affect comprehension. With regard to instructional design, system approaches are sometimes referred to as instructional development systems (IDS). An IDS embraces several major categories. These include a statement of goals, analysis, development of instruction, and evaluation and revision. General statements on CAI can be divided into the following areas: requirements, potential benefits, state of the art, problems, CAI as a factor in society, the roles of industry, education, and government, including the role of teacher. At least two educational requirements make CAI inevitable, i.e., the trend to individualized instruction and the growth in information to be acquired. Data processing and computer science involve the teaching of computer skills in relative isolation from other disciplines. Hence, the computer is the principal subject. Student problem solving and research is where the computer is used as a tool in some field outside computer science. A specific sphere of application is the subject. This article will relate these categories as they apply to an introductory computer concepts course taught at the undergraduate level. Another phase of this course is that it is accounting-oriented.

This article reviews that deepwater oil platforms are kept afloat and the oil they produce is kept pumping with the help of a host of advanced technologies. Not the least among them is the technologies that play a particularly strong role in calculating the critical operations of large oil rigs, like that of the Chevron Genesis project. The Genesis platform is located in water where weather is powerful and changeable, and is therefore always a concern. The crew must be ready to deal with weather at a moment’s notice, and also must deal with the day-to-day events of life aboard an oil drilling plat form. Software also plays a role in positioning the risers. They must be located in such a way as to allow them to remain standing against the force of the waves in deep waters. Piping systems are often designed and laid out in a computer-assisted drawing or modeling program. The plan for the pipes is downloaded from the design system to the analysis program in order for engineers to study the structure and to calculate stresses and loads.

The computer-assisted configuration of progressive die is a computationally mixed problem. This paper describes the progressive die design problem and reviews some existing research related to the configuration of progressive dies. It explains the model-based reasoning approach used to configure the intermediate and final solutions to the design problem. In particular, the various shape representation and spatial reasoning techniques are presented. Finally, a computer software architecture for the die design system is presented.
