BOINC (Berkeley Open Infrastructure for Network Computing) is an open-source framework for solving large-scale and complex computational problems by means of public resource computing (PRC). In contrast to massive parallel computing, PRC applications are distributed onto a large number ... En savoir plus

The paper demonstrates that for some models a 2D geometry in Cartesian coordinates can be used to obtain a 3D solution with changes in z-direction. A heat exchanger serves as an example of a practical application. The required flow rate in a straight cooling pipe penetrating ... En savoir plus

Singlet oxygen (1O2) is the major cytotoxic agent in photodynamic therapy (PDT). The reaction between 1O2 and tumor cells defines the treatment efficacy. Based on a previously developed model that incorporates the diffusion equation for the light transport in tissue and the macroscopic ... En savoir plus

For this work the multi-objective design environment modeFRONTIER was integrated with COMSOL, bringing the advantages of multi-objective optimization to multiphysics simulations. Practically any commercial analysis tool (such as COMSOL) or in-house code can be integrated within ... En savoir plus

Singlet oxygen (1O2) is the major cytotoxic agent during type-II photodynamic therapy (PDT). The production of 1O2 involves the complex reactions among cancer agent, oxygen molecule, and treatment laser light. The light propagation in tumor tissue is described by the diffusion equation. ...

In this paper we present a novel approach for modeling spatial distributed bio- chemical and environmental processes like the growth of plants and the related biochemical reactions. The physical phenomena like flow and mass transport can be described by fluid dynamics equations, but for ... En savoir plus

Objective of this contribution is to present a procedure for evaluating second order drift forces on floating bodies, often the most important loading component for mooring design, in case of high waves propagating in relatively shallow water depths. The non linearity associated to this ... En savoir plus

The inverse diffusion problems deal with the estimation of many crucial parameters such as the diffusion coefficient, source properties, and boundary conditions. Such algorithms are widely applied in many design problems in different physical, chemical, and biological fields. Recently, ... En savoir plus

This work concerns the development of a new direct parameter identification procedure for a class of nonlinear reaction- diffusion equations. We assume to know the model equations with the exception of a set of constant parameters, such as diffusivity or reaction term parameters. Using ... En savoir plus

Capacitive MEMS (Micro-Electro-Mechanical Systems) accelerometers may be directly soldered to the printed circuit board by an array of solder balls. Differences in the thermal expansion coefficients of the pertinent materials cause deformations of the accelerometer under temperature ... En savoir plus
