In order to design new search strategies for collaborating autonomous underwater vehicles, a 2D simulator was developed to simulate costal water environments. This allows for evaluating the new strategies without running the risk of losing expensive hardware during the tests. The simulator developed is based on the concept of cellular automata. Details of the simulator are described before prel...

The concept of continuous proces s improvement, although familiar in the manufacturing arena, is just starting to b e implemented in the software industry . Currently, software developmen t organizations have identified potentia l process improvements and are working to implement results from ISO 9000 audits an d Capability Maturity Model (C M M ) Software Process Assessments . Quantitative met...

Visualising is a method used to help experiencing a nd understanding causal cohesions in simulation processes. For this purpose, tools for visualising are already implemented in prevalent simulation systems. The user creates his simulation model and generates a 3-dimensional (2,5-dimensional) visualising by means of the simulation system. This helps examining the process which makes it easier f...

An increasing number of enterprise information systems uses modern software tools such as workflow management systems and enterprise resource planning systems to support the control, co-ordination, monitoring, and execution of business processes. As a result, these enterprise information systems have knowledge of the business processes, of the current state of each process, and of historical da...

CNG vessels are used in many vehicles.  Mass production of CNG pressure vessels requires exact understanding of process effective parameters.  In this paper, the numerical analysis has been used to study the manufacturing parameters.  The entire manufacturing processes, including deep drawing, redrawing and ironing, of an aluminum liner sample of CNG pressure vessel (without spinning) have been...

The use of computer simulation has increased rapidly within the construction industry over the last few years and this trend is set to continue. However, it is important not to forget that physical testing methods still have a vital role in establishing the validity of and confidence in simulation modelling results. This paper reports on the experience of modelling in excess of 10 large shoppin...

A new parallel semiconductor device simulation using the dynamic load balancing approach is presented. This semiconductor device simulation based on adaptive finite volume, error estimation, and monotone iterative methods has been developed and implemented on a Linux-cluster with MPI library. Two different parallel versions of the algorithm to perform a complete device simulation are proposed. ...

The RUMORS synthesizer of Russian is a,~ integral part of the JM~AP experimental system of ,ht.pn.neseRussian antom.t~tic translation, although it cn,n also h~ve other ~ppliczrtions. Morphologically, it is based, primtrrily, on A.A.ZMizny~k's model of Russi~t. inflexion. Syntactical functions of RUMORS rely on word-order ~nd dependency d~t~ as input information. The synthesizer is implemented o...

The human auditory system relies strongly on differences in time and intensity between the two ears to localize correctly a sound source. Bilateral or independent hearing aids distort this information. Van den Bogaert, et al. (2005) showed that, in an anechoic environment, sound localization is better without hearing aids than with. In this study, we investigated how hearing aids modify our loc...
