The paper presents a computer-based method for the multicriteria conceptual design of engineered artifacts. The proposed method involves genetic-based stochastic search, Pareto optimization, and color-filtered graphics. A multicriteria genetic algorithm broadly searches the governing body of design knowledge and identifies Pareto designs that are equal-rank optimal in the sense that each is not...

D. Ifenthaler and R. Hanewald (eds.), Digital Knowledge Maps in Education: TechnologyEnhanced Support for Teachers and Learners, DOI 10.1007/978-1-4614-3178-7_2, © Springer Science+Business Media New York 2014 Abstract Digital knowledge maps are rich sources of information to track students’ learning. However, making sense of concept maps has been found challenging. Using multiple quantitative ...

This paper seeks to establish the conceptual and empirical basis for an innovative instrument of corporate knowledge management: the knowledge map. It begins by briefly outlining the rationale for knowledge mapping, i.e., providing a common context to access expertise and experience in large companies. It then conceptualizes five types of knowledge maps that can be used in managing organization...

Human-computer interaction is often a bottleneck in the application of CAD during the conceptual phases of the design process. Current CAD systems generally are not able to support conceptual design in a convenient way. Effective human-computer interaction (HCI) should allow the performance of ideating activities. An empirical study was performed to observe which activities designers naturally ...

Cognitive map is a comprehensive research field of many disciplines, such as psychology, geography, computer science, and sociology. This multidisciplinary synthesis reflects the complexity cognitive itself, which until now has lacked unified conceptual definition because its complexity. The literature on maps increasing yearly, but few bibliometric studies exist. To fill this gap, paper uses r...

Evolution is one of the major issues affecting system dependability as well as engineering activities and environments. The most common understanding considers evolution as a phenomenon that needs to be avoided. By contrast this paper takes into account evolution as a necessary feature of computerbased systems. This paper reviews a taxonomy of evolution identifying a conceptual framework to ana...

In computer science and mathematics education, universities often observe high failure rates among students if they are taught in a traditional, lecturecentric manner. Interactive engagement teaching methods are more successful but in order to develop suitable teaching materials, lecturers must be aware of potential conceptual difficulties of a domain in advance, for example, by analysing the d...

Presented in this paper is a conceptual design by computer simulation of monopulse reflector antenna with dual-circularly polarized sum patterns and linearly azimuth elevation difference patterns, which can be called semi-dual antenna. The proposed consists five-element feed prime-focus parabolic reflector. novelty the consisting square waveguide channel radiator rectangular radiators. separati...
