An experimental program has been developed, with the purpose of evaluating the reliability in building diagnosis and characterization of an integrated analysis of several parameters, associated with acoustic waves propagating through the material. The Direct Transmission Technique has ... En savoir plus

The use of foundation piles as ground heat exchangers coupled to a geothermal heat pump is considered of interest for possible savings in installation costs, compared to conventional borehole heat exchangers. We refer to them as “geothermal piles” or “energy piles”. The main purpose of ... En savoir plus

Micro-sized separation devices are in a state of research globally due to its simplicity; cost effectiveness and high precision for analyzing biological and medical samples, e.g. blood cells. Magnetophoresis is a technique to separate cells on biochip by manipulating the magnetic ... En savoir plus

Monitoring of indoor CO2 concentration is of particular interest to detect room occupancy in order to optimize power consumptions of building. One approach to monitor the indoor CO2 concentration is to use optical detection using specific absorption lines of CO2 molecules in the infrared ... En savoir plus

The scientific method requires techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge [1]. The Oxford English Dictionary defines the scientific method as "a method or procedure that has characterized natural science since the ... En savoir plus

Directional couplers are used for the purpose of redirecting, splitting, and combining light in silicon photonic circuits. They are used extensively in data communication applications such as wavelength-division-multiplexing and signal switching [1]. Their functionality is an integral ... En savoir plus

This paper describes COMSOL Multiphysics® simulations of the stress and crack development in the area where a masonry wall supports a floor. In these simulations one of the main material properties of calcium silicate, its E-value, was assigned randomly to the finite elements of the ... En savoir plus

The heat transfer rate and borehole design represent great challenges to thermal equipment designer of the ground-coupled heat pump. The present model represents a mathematical numerical technique implemented to tackle such problem. A thermal assessment was established to estimate the ... En savoir plus

Arches being one of the most aesthetic and stable form of structural elements, have been constantly used since hundreds of years in various form of constructions be it buildings, bridges or any other structural system. Though, common use of reinforced concrete framed structures has ... En savoir plus

This paper demonstrates experience of using the COMSOL Multiphysics® transport phenomena models in design practice, particularly at the early stage of design when there is might be too many possible design suggestions relying on the shell balance equations, and engineering intuition. ...
