This paper describes a multi-material virtual prototyping (MMVP) system for modelling and digital fabrication of discrete and functionally graded multi-material objects for biomedical applications. The MMVP system consists of a DMMVP module, an FGMVP module and a virtual reality (VR) simulation module. The DMMVP module is used to model discrete multi-material (DMM) objects, while the FGMVP modu...

The area of the Dansuie River watershed located in the northern Taiwan is 2,726 km. The main stream runs 159km through the Taipei metropolitan areas as the political, economic, and cultural centers of Taiwan. Owing to short and steep runoff path-lines and non-uniform rainfall patterns, large floods arrive rapidly in the middle-to-downstream reaches of the watershed, causing serious damage. In o...

In this paper, we present a new method to design and realize chatting module in online virtual campus system. Our virtual campus system is based VRML (Virtual Reality Modeling Language) and JavaScript, and has two parts, including server and client. We divide the system into several different modules, including user interface, models database, information database, navigation graph, chatting mo...

Modern psychological theories of spatial cognition postulate the existence of a ‘geometric module’ for reorientation. This concept is derived from experimental data showing that in rectangular arenas with distinct landmarks in the corners, disoriented rats often make diagonal errors, suggesting their preference for the geometric (arena shape) over the non-geometric (landmarks) cues. Moreover, e...

We introduce deformations of the space of (multi-diagonal) harmonic polynomials for any finite complex reflection group of the form W = G(m, p, n), and give supporting evidence that this space seems to always be isomorphic, as a graded W -module, to the undeformed version. Résumé. Nous introduisons une déformation de l’espace des polynômes harmoniques (multi-diagonaux) pour tout groupe de réfle...

We describe project deLearyous, in which the goal is to develop a proof-of-concept of a serious game that will assist in the training of communication skills following the Interpersonal Circumplex (also known as Leary’s Rose) –a framework for interpersonal communication. Users will interact with the application using unconstrained written natural language input and will engage in conversation w...

This paper considers the job scheduling problem in virtual manufacturing cells (VMCs) with the goal of minimizing two objectives namely, makespan and total travelling distance. To solve this problem two algorithms are proposed: traditional non-dominated sorting genetic algorithm (NSGA-II) and knowledge-based non-dominated sorting genetic algorithm (KBNSGA-II). The difference between these algor...

Significant progress in the development and commercialization of electrically conductive adhesives has been made. This makes shingling a very attractive approach for solar cell interconnection. In this study, we investigate shading tolerance two types modules based on shingle interconnection: first, already commercialized string approach, second, matrix technology where cells are intrinsically ...

The design and main characteristics of 14-channel dispersion interferometer for plasma profile measurement and control in TEXTOR tokamak are presented. The diagnostic is engineered on the basis of modular concept, the 10.6 microm CO(2) laser source and all optical and mechanical elements of each module are arranged in a compact housing. A set of mirrors and retroreflectors inside the TEXTOR vac...

This paper presents a method of warehouse simulation model implementation using concepts of virtual reality (VR). The basic idea is to compare the "real process" controlled by operator with his/her heuristics to the "virtual process" represented by a simulation model, controlled by the optimization algorithm. The optimization algorithm is based on a SD model of the warehouse and decision suppor...
