A 2D transient heat conduction model was created in COMSOL Multiphysics® software to study the performance of photovoltaic-thermal (PVT) water system. The model captures the variation of important environmental and system parameters such as outside temperature, solar irradiation, air ... En savoir plus

A growing demand is recently emerging of sensors to be integrated in the concrete in order to measure some critical parameters, such as humidity and temperature and the internal pressure of the material. For example, by monitoring the pressure in various strategic points of the structure ... En savoir plus

INTRODUCTION: Microfluidics, as a crucial technology of recent years, enables numerous applications for Point-of-Care-Testing such as Lab-on-Chip-Systems (LOC) or Micro-Total-Analysis-Systems (µTAS) and is exceptionally well-suited for cell sorting or DNA trapping. Especially the ... En savoir plus

There is a considerable world-wide interest among lightning protection engineers and designers on the improvement of the standard procedures to assess the location of the most vulnerable places on complex structures to be struck by lightning flashes. This paper presents the ... En savoir plus

Finite element analysis (FEA) can be used to study the electrical properties of conductive ITO thin films. Previous studies have been done on insulating thin films deposited on conductive substrates [1,2]. It was found that changes of electrode size and film thicknesses can cause huge ... En savoir plus

This report addresses design of a PCB intended for use as a busbar integrated with multiple DC-link (rail) capacitors in a high power inverter. The geometry and current ratings are typical of a 50 kW unit operating at 60kHz in an intermittent mode. First, circuit aspects are analyzed. ... En savoir plus

The simulation of heat and moisture transfer represents an essential resource in designing energy efficient buildings. In this paper a time-dependent wall model, consisting of several homogeneous domains, with third-type boundary conditions imposed on the surfaces, is implemented in the ... En savoir plus

Geothermal heat pumps use the earth as a heat source and sink via a ground heat exchanger (GHX) that consists of a network of buried heat exchange pipes, which can either be installed in vertical boreholes or in shallow horizontal trenches or excavations. The main goal in GHX design is ... En savoir plus

One of the most promising categories of semiconductor-based sensors is organic electrochemical transistor (OECT), which consists of three electrodes (Source, Drain and Gate) and two active layers: electrolyte and conductive polymer. Despite the fact that OECT attracts a lot of attention ... En savoir plus
