Modeling the human arm and calculation of the human arm reach are important for designing workspaces. An appropriate workspace design would reduce musculoskeletal disorders and wrist injuries in repetitive tasks. Among different human arm workspace designs and reach calculations, computer-based methods have recently attracted significant attention. This is because conventional experimental methods do not provide sufficient flexibility for interactive design modifications and integration of different aspects for workspace design. Despite advances in computer-aided design, many computer-based methods still rely on mock-ups and experimental set-ups. In this work, a computer-aided method is investigated for predicting the human arm reach. The kinematic modeling convention of Denavit-Hertenberg is adopted for formulating the reach. Simulation results are provided to demonstrate the effectiveness of the method. The methodology enables visualization of the reach volume of the human arm and could be easily adjusted for different human operators.

Laboratory work is an important element in engineering training, which should correspond to up-to-date tendencies in computer-based technologies in design, production, maintenance and preserving mechanisms. Computer-based laboratory work consists of 16 assignments. Seven assignments are carried out on laboratory stands, the remainder are provided on PC, using programs like “Visual Structure Editor”, “DYNAMO”, “APM Win Machine”. The system Visual Structure Editor (VSE) is designed by specialists of “Machine Mechanics and Computer-Aided Design” department, of the Maritime State University named after adm.G.I.NEVELSKOY, Vladivostok, under the direction of prof. Valentina V. Kuzlyakina. The system APM (Automated Projecting of Mechanism) is designed by the research-and-production centre “APM” under the direction of prof.V.Shelofast, from the city of Korolyov, Moscow area. These systems are multifunctional. They allow project different mechanical systems at the stage of structural and parametrical synthesis, carry out strength calculations and design elements of machines and mechanisms. They are good in operation. Teachers and students easily master the systems. Laboratory works with computer support allow students to pass from a concrete object to modeling on a PC, and to solve complex engineering tasks during the education process.

Aided Design

The modification of the caisson in a dry dock is in many ways more difficult than conventional ship modifications. This is because of the accuracy required, location of the measurements, and the size of the structure. The development of computer-based multi-headed electronic theodolite systems made it possible to extract accurate data on large structures. These data were formatted so they could be input directly into a computer-aided design system. The multi-headed electronic theodolite system was used to transfer new design information directly to the structure. The caisson structure was modified and moved safely into position with the aid of a water castor system for final assembly. Final dimension checks verified the accuracy of the system.

The use in design, of knowledge and understanding of human thermal comfort, heat stress and cold stress, is often complex and time consuming. A computer based system (IBM-PC) was developed to allow human factors practitioners to assess and manipulate knowledge, data and simulations of human response to thermal environments, thus allowing computer aided design. A description of the system, its design and development and examples of its use are provided. The role of such systems in design and assessment should be considered by human factors practitioners.

Attempts to include Computer-Aided Design and Computer-Assisted Learning facilities in a substantial way into undergraduate teaching lead inevitably to a consideration of appropriate (efficient) methods of instruction. A method based on syndication of tasks, used at Ulster Polytechnic, is described. The method has been found particularly useful in teaching System Dynamics and Control.

Abstract In the process of development of Computer Aided Design (CAD) software tools, the expected functionality reappears in various different forms, for instance, as a collection of theories, methods, algorithms or as pilot implementations. Ensuring quality of these abstract software implementations can help assuring the acceptance of the functionality. The problem is that a formal methodology for assuring quality of all these abstract implementations is not available. As an attempt to deal with this challenge, we have developed a computer based pre-implementation testing methodology that has been named abstract prototyping. The exclusive feature of the abstract prototyping technique and the philosophy behind it is that it provides a framework for pre-implementation testing and for involving the representatives of various stakeholders in the development and testing of incidental implementations. We are using abstract prototyping as a framework for development and testing of abstract implementations of design support software tools, and it appears to be useful. It provides the developers with a methodology for exploring views of various stakeholders. It thus helps reduce the risk of developing poor design support software tools. In this paper we first review the problem and then briefly introduce the abstract prototyping concept and software tools. Afterwards, we focus on explaining how to use the abstract prototyping technique in the development and testing of design support software tools.

This paper presents a study of the process of virtualization or a cultural heritage modeling of Joglo house, an old Javanese house, through observation method. The method consists of three aspects as the following: (1) to observations and measurements, (2) to create a virtual image of the cultural heritage and (3) to integrate the all component of the cultural heritage house, so that the final image is expected to be the replicate of the original house. Additionally, in the process of making traditional Joglo house model, there is another aspect that has been conducted, it was to create harmony between the display of a merger of two and three-dimensional photorealistic models which was made with the help of computer-based applications, namely Computer Aided Design (CAD). As such, by implementing these methods, the reconstruction of cultural heritage of the Joglo house, the Kartasura, can be realized.
