An effort is made to give a description of a computer-aided conceptual design system. A novel Function-Action-Behavior-Mechanism (FABM) modeling framework is proposed to realize mapping from the overall function to principle solution according to customer’s requirements. Expansion and modification rules in the demand behavior are developed to extend the innovation of principle solution. A case study on pan mechanism design for cooking robot is presented to show the procedure of how to implement the intelligent reasoning based on the FABM model.

The purpose of this article is to justify the need for evidence-based design (EBD) in a research-based architecture and design practice. This article examines the current state of practice-based research (PBR), supports the need for EBD, illustrates PBR methods that can be applied to design work, and explores how findings can be used as a decision-making tool during design and as a validation tool during postoccupancy. As a result, design professions’ body of knowledge will advance and practitioners will be better informed to protect the health, safety, and welfare of the society. Furthermore, characteristics of Friedman’s progressive research program are used as a framework to examine the current state of PBR in design practice. A modified EBD approach is proposed and showcased with a case study of a renovated inpatient unit. The modified approach demonstrates how a highly integrated project team, especially the role of design practitioners, contributed to the success of utilizing baseline findings and evidence in decision-making throughout the design process. Lastly, recommendations and resources for learning research concepts are provided for practitioners. It is the role of practitioners to pave the way for the next generation of design professionals, as the request and expectation for research become more prevalent in design practice.

Theoretical Foundations

Genetic Algorithms (GA), which are based on the idea of optimizing by simulating the natural processes of evolution, have proven successful in solving complex problems that are not easily solved through conventional methods. This chapter introduces their major steps, operators, theoretical foundations, and problems. A parallel GA is an extension of the classical GA that takes advantage of a GA’s inherent parallelism to improve its time performance and reduce the likelihood of premature convergence. An overview of different models for parallelizing GAs is presented along with a discussion of their main advantages and disadvantages. A case study: A parallel GA for finding Ramsey Numbers is then presented. According to Ramsey Theory, a sufficiently large system (no matter how random) will always contain highly organized subsystems. The role of Ramsey numbers is to quantify some of these existential theorems. Finding Ramsey numbers has proven to be a very difficult task that has led researchers to experiment with different methods of accomplishing this task. The objective of the case study is both to illustrate the typical process of GA development and to verify the superior performance of parallel GAs in solving some of the problems (e.g., premature convergence) of traditional GAs.

Management of fixture design knowledge is vital for improving product quality and reducing product lead time, but there is no efficient and effective mechanism in current computer-aided fixture design systems to integrate fixture design process, to share design resource as well as acquisition and reuse knowledge. Ontology is increasingly seen as a key technology for enabling semantics-driven knowledge processing. On the background of a architecture of fixture design system based on knowledge introduced in the paper, we presented and expatiated a fixture design knowledge acquisition and reuse technology based on ontology, which embeds ontology in current computer-aided fixture design based on knowledge. Finally, the related case study was given.

The paper introduced a computer-aided industrial design system: Forklift Truck’s Multi Plan Optimizaion System, and demonstrated the modules’ function and techniques with examples. Considering the requirements for efficiency and precision in the forklift styling, the author developed the forklift optimizing software for its styling, which includes parameter optimization, color optimization and part combination three modules. The parameter optimization module can vary the user defined parameters of the forklift models and generate new models. Color optimization module can group the model surfaces and render the groups with different color. New color plans are generated through random changing of the colors in each group. The parts combination module divides forklift into several parts and build lib for each part. The module can pick parts from the lib and assemble them into a whole forklift and demonstrate them. The thesis developed a proto system on the Solidworks platform with VBA programming tools. Interactive genetic algorithms are applied to realize the three module’s function.

KINSYN III is the latest version of a computer-aided linkage design system with features not previously described. Concentrating on the new features, this paper describes the system and includes case study photographs. The system has capabilities for either synthesizing or constructing pin- or slider-jointed planar linkages of almost any topology and for analysis of this same class of mechanisms. Emphasis is on synthesis techniques and man-computer graphical interaction. Problems in linkage synthesis and design are discussed along with KINSYN III’s interactive approach to their solution.

Abstract IS / ICT is dictating the world in terms of service provision, and more so in education and the financial sector such as electronic money transfer. The article has provided a review of Information Science (IS) in the light of its wider interpretation in different walks of life. The current state of IS / ICT provision is also addressed, with the need to focusing attention in improving the country's capacity in meeting global demand for services. Qualitative interpretation of themes was used in helping to provide critical approach in unravelling issues for the good of the nation. Recommendations pointed to an enhancement in the infrastructural capacity, and also human resources to address on-going demands. IS / ICT capacity around the world is changing and so too is the need for the country to build on its human resource potential to address threats posed, from within and outside of the country, while at the same time focusing attention in enhancing the green economy.

The manner in which golfers think on the golf course significantly influences their performance. In 2008, the author provided an overview of golf-specific mental skills with the intention of raising golf coaches' awareness of psychological techniques they could use to help their golfers think more effectively. The aim of this paper is to follow up the author's overview by providing an introduction to mental skills interventions, specifically focusing on how they can be tailored to individual golfer's needs, and how they can be applied, analysed, and evaluated to facilitate the performance of competitive golfers. This five-part paper will: 1) outline the current state of formal mental skills education among golf coaches; 2) introduce selected theories that underpin mental skills interventions; 3) address the role of golf coaches in delivering these interventions; 4) suggest some frameworks which might help to increase the effectiveness of these interventions; and 5) illustrate the practical application of these theories and frameworks by describing a mental skills intervention that was used with a tour-level golfer to improve playing performance.
