Energetic Macroscopic Representation and PSIM® simulation: application to a DC/DC converter input filter stability

Philippe Barrade

Simulation is a key issue in the design of control electrical systems. Simulation packages using component library, such as PSIM®, are very useful to achieve this goal. The simulation model is thus easily built from the system topology (structural model). ...

Experimental techniques in molecular biology have led to the production of enormous amounts of data on the dynamics of cellular processes. The availability of time series data characterizing genomic, proteomic and metabolic systems must be complemented wit ...

Simulating real DSP code using a DLL, application to a 3-level VSI SVC

Jean-Jacques Simond, André Hodder, Roland Wetter, György Atilla Bànyai

The present paper addresses the use of a Windows™ DLL to simulate the real code of a DSP for faster development time and advanced testing, especially in high power systems. The development of power system control usually starts with simulations and the dev ...

A Generic Approach by Non-linear Optimisation for Complex Processes Application Example Coordinated Control in Combined Sewer Networks

The algorithm based on nonlinear optimisation as presented in this paper is applicable to the control of complex processes. The systematic approach is doing without the formulation of rules. In case of competing control targets a weighting in the sense of ...

2009

Software engineering always cares to provide solutions for building applications as close as possible to what they should be, according to the requirements and the final users needs. Systems behavior simulation is a very common application to virtually rep ...

How (Un)Fair are the ABR Binary Schemes, Actually?

Jean-Yves Le Boudec, Milan Vojnovic

It is well known that a simple binary feedback rate--based congestion avoidance scheme cannot ensure a fairness goal of the Available Bit Rate (ABR) service, namely, max-min fairness. In this paper we show how the rates are distributed for the network cons ...

This paper deals with a new discrete event simulation modeling concept, called qobj, which comes from two well-known paradigms: objects and queuing networks. The first provides important conceptual tools for model organization, while the second one allows ...
