The paper presents integrative model-based approach in application of virtual engineering technologies in rapid product and process design and manufacturing. This has resulted in integration of so called CAtechnologies and Virtual Reality in product design and FE numerical simulations and optimization of production processes, as digital prototyping of product and processes, from one side, and r...

Rapid prototyping has become an innovative method of fast and cost-effective production of three-dimensional models for manufacturing. Wide access to advanced medical imaging methods allows application of this technique for medical training purposes. This paper presents the feasibility of rapid prototyping technologies: stereolithography, selective laser sintering, fused deposition modelling, a...

A cost effective, gesture based modelling technique called Virtual Interactive Prototyping (VIP) is described in this paper. Prototyping is implemented by projecting a virtual model of the equipment to be prototyped. Users can interact with the virtual model like the original working equipment. For capturing and tracking the user interactions with the model image and sound processing techniques...

A technique to include virtual prototyping in the design cycle of complex digital modem ASICs is presented. It is innovating by using the same behavioral description for both the prototype as well as the final circuit implementation. Relating to verification of the design, this is a crucial benefit. The article discusses the prototyping mechanism by using the design of an upstream cable modem A...

This paper presents a requirements elicitation approach that is based on model-driven prototyping. Model-driven development fits naturally in evolutionary prototyping because modeling and design are not treated merely as documents but as key parts of the development process. A novel rapid program synthesis approach is applied to speed up the prototype development. MDA, AI planning, and componen...

Many diseases and health risks are the result of unhealthy lifestyles and technology could be used as an intervention. However, designing healthy lifestyle technologies is challenging, as the technology should be able to influence user behavior. In this case study, the design and evaluation process of a persuasive healthy lifestyle assistance technology was investigated. The iterative design an...

Research and development on actuators has been accelerated with the aid of virtual prototyping software, like ANSYS. This is illustrated with two successful cases using ANSYS to design and optimize micro-electromechanical actuators. The first case is topology optimization of head suspension assembly for hard disk drive. The second case is design optimization of polymeric thermal micro-actuator....

To improve the market competitiveness of enterprises in the manufacturing industry, some of them involve picking the most appropriate strategies among multiple available alternatives. However, no single alternative works is suitable for all evaluation criteria which must be considered during the selection processes. This paper proposes a new hybrid MCDM method using design of experiment (DoE) a...
