original article     the aim of this study was to design and build a software for noise propagation prediction (indoor and from indoor to outdoor spaces) which is being commonly used in industry.  in this regard, firstly a mathematical complex model was created based on existing relationships about noise propagation in indoor spaces and transmission through the walls and propagation in outdoor ...

Standard rapid-prototyping systems for real-time applications are usually equipped with x86-based PCs for software development and additional DSP processors to do the real-time work. Using a DSP always requires tools and compilers which in most cases must be purchased and are licensed by the vendor of the DSP, increasing the cost of the system. This paper presents a rapid-prototyping system bas...

In this paper, PC SAS/IML® modules are developed which calculate percentile method confidence intervals and vanants. The modules will work on distributions of parameters generated by any Monte Carlo technique, Including the bootstrap.

We present a Virtual Reality (VR) tool for exploration of three-dimensional cellular automata. In addition to the traditional visual representation offered by other implementations, this allows users aurally render active (alive) cells an automaton in sequence along one axis or simultaneously create melodic and harmonic textures, while preserving all cases relative locations these user. The aud...

We propose a method of generating natural-looking behaviors for virtual characters using a data-driven method called behavior capture. We describe the techniques for capturing trainer-generated traces, for generalizing these traces and for using the traces to generate behaviors during game-play. Hidden Markov Models (HMMs) are used as one of the generalization techniques for behavior generation...

We report on a project which is exploring how the technology and language of computer games can be used to create novel resources for anatomy education. We present our experiences of developing a simple anatomy game, with an emphasis on software development issues, and offer this as a case study for those wishing to create 3D educational content within an academic context.

We examine the importance of office suites for the evolution of the PC office software market in the 1990s. An estimated discrete demand choice model reveals a positive correlation of consumer values for spreadsheets and word processors, a bonus value for suites, and advantages for Microsoft products. We employ the estimates to simulate various hypothetical market structures to evaluate the pro...

The voice controlled wheel robot system needs to make use of the latest technological components available. In this paper, we present the design and implementation of a voice based wheel chair system where communication technologies and Internet have been used. All these techniques are successfully merged in a voice controlled wheel chair system. With this, the fully designed voice controlled s...

This paper describes an approach to the feature location problem for distributed systems, that is, to the problem of locating which code components are important in providing a particular feature for an end user. A feature is located by observing system execution and noting time intervals in which it is active. Traces of execution in intervals with and without the feature are compared. Earlier ...
