Web-based simulationWeb-based simulation (WBS) is the invocation of computer simulation services over the World Wide Web, specifically through a web browser. Increasingly, the web is being looked upon as an environment for providing modeling and simulation applications, and as such, is an emerging area of investigation within the simulation community. Web-based simulation is used in several contexts: In e-learning, various principles can quickly be illustrated to students by means of interactive computer animations, for example during lecture demonstrations and computer exercises.
Équation différentielle linéaireUne équation différentielle linéaire est un cas particulier d'équation différentielle pour lequel on peut appliquer des procédés de superposition de solutions, et exploiter des résultats d'algèbre linéaire. De nombreuses équations différentielles de la physique vérifient la propriété de linéarité. De plus, les équations différentielles linéaires apparaissent naturellement en perturbant une équation différentielle (non linéaire) autour d'une de ses solutions.
Méthode des éléments finis de frontièreLa méthode des éléments finis de frontière, méthode des éléments frontière ou BEM - Boundary Element Method - en anglais, est une méthode de résolution numérique. Elle se présente comme une alternative à la méthode des éléments finis avec la particularité d'être plus intéressante dans les domaines de modélisation devenant infinis. Méthode des moments (analyse numérique) Méthode des différences finies Méthode des volumes finis Méthode des éléments finis Méthode des points sources distribués Introduction à l

Numerical methods for partial differential equationsNumerical methods for partial differential equations is the branch of numerical analysis that studies the numerical solution of partial differential equations (PDEs). In principle, specialized methods for hyperbolic, parabolic or elliptic partial differential equations exist. Finite difference method In this method, functions are represented by their values at certain grid points and derivatives are approximated through differences in these values.
First-order partial differential equationIn mathematics, a first-order partial differential equation is a partial differential equation that involves only first derivatives of the unknown function of n variables. The equation takes the form Such equations arise in the construction of characteristic surfaces for hyperbolic partial differential equations, in the calculus of variations, in some geometrical problems, and in simple models for gas dynamics whose solution involves the method of characteristics.
Computational resourceIn computational complexity theory, a computational resource is a resource used by some computational models in the solution of computational problems. The simplest computational resources are computation time, the number of steps necessary to solve a problem, and memory space, the amount of storage needed while solving the problem, but many more complicated resources have been defined. A computational problem is generally defined in terms of its action on any valid input.
Computational complexityIn computer science, the computational complexity or simply complexity of an algorithm is the amount of resources required to run it. Particular focus is given to computation time (generally measured by the number of needed elementary operations) and memory storage requirements. The complexity of a problem is the complexity of the best algorithms that allow solving the problem. The study of the complexity of explicitly given algorithms is called analysis of algorithms, while the study of the complexity of problems is called computational complexity theory.
Simulateur logiqueLogic simulation is the use of simulation software to predict the behavior of digital circuits and hardware description languages. Simulation can be performed at varying degrees of physical abstraction, such as at the transistor level, gate level, register-transfer level (RTL), electronic system-level (ESL), or behavioral level. Logic simulation may be used as part of the verification process in designing hardware. Simulations have the advantage of providing a familiar look and feel to the user in that it is constructed from the same language and symbols used in design.
VHDLVHDL est un langage de description de matériel destiné à représenter le comportement ainsi que l'architecture d’un système électronique numérique. Son nom complet est VHSIC Hardware Description Language. L'intérêt d'une telle description réside dans son caractère exécutable : une spécification décrite en VHDL peut être vérifiée par simulation, avant que la conception détaillée ne soit terminée.
