This paper presents a few examples of the possibility of effective use of open-source simulation tools within the project gsim to solve the problems of the electronics in educational and professional practice. The fundamental difference with regard to commercial products are open file and data formats, the possibility of creating own components and macro models. An essential advantage is the easy...
Some modelling methods and associated tools are presented in this paper to efficiently and accurately simulate the electromagnetic behaviour of power electronic structures. Moreover, as engineers have to face new challenges, the synergy between simulation tools is illustrated as a possible solution for addressing this "multiphysic" topic. The article is also pictured of several application...
This paper proposes and illustrates an approach to identify and specify requirements on information-based business services and their associated derived software services. The approach proposes first to identify business services by modeling business requirements using the goal oriented modeling notation i*. Then, in a second phase, the identified services are refined according to these requirements...
The complexity of automation systems increases steadily. Modeling is widely seen as important lever to cope with the complexity in development. Abstract models are used for analysis and representation of complex interrelations as it is possible to concentrate on the essential aspects. As most models are used for analysis and documentation within only one single development step, the information accumulated...
The challenges of deriving early-adopter competitive advantage, even with fabless access to process technology, through leveraging features offered by the advanced, and possibly disruptive, process technologies in real SoC products, are outlined. A structured methodology for addressing these challenges, and bridging the gap between process and design, sufficiently early in the development cycle to...
We present an approach for automated evolutionary design of the functionary of driving agent, able to operate a software model of fast running car. The objective of our work is to automatically discover a set of driving rules (if existent) that are general enough to be able to adequately control the car in all sections of predefined circuits. In order to evolve an agent with such capabilities, we...
In this paper, based on ordered Hadamard transform and its probability model, a fast partial distortion elimination algorithm is proposed. For lossless motion estimation, we propose DC and AC constraints to model local block complexities using ordered Hadamard transform. Using sum of these constraints, we obtain the optimized search order in the matching error calculation by descending order of local...
Search-based software testing (SBST) has shown a potential to decrease cost and increase quality of testing- related software development activities. Research in SBST has so far mainly focused on the search for isolated tests that are optimal according to a fitness function that guides the search. In this paper we make the case for fitness functions that measure test fitness in relation to existing...
Video-streaming can now be offered on third-generation (3G) mobile networks. Most research efforts have focused on video download. This paper presents a detailed study of challenges faced for successfully deploying applications requiring life video upload. Both subjective and objective qualities as well as the effects of mobility are analyzed on real 3G networks. Consequently, video profiles are identified...
A formalism for modeling hybrid dynamical systems is presented. Unlike most work on hybrid dynamical systems where the objective of model construction is system analysis and controller synthesis, the objective here is to construct a formalism suited for modular model construction and simulation. This formalism is used in the open-source modeling and simulation software Scicos
