—Energy storage components improve the energy efficiency of systems by reducing the mismatch between supply and demand. For this purpose, phase change materials are particularly attractive since they provide a high energy storage density at a constant temperature which corresponds to the phase transition temperature of the material. Nevertheless, the(More)
a a Chaire de recherche industrielle en technologies de l'´ energie et en efficacitéénergétique (t3e), ´ Abstract This paper deals with the estimation of optical property distributions of participating media from a set of light sources and sensors located on the boundaries of the medium. This is the so-called diffuse optical tomography problem. Such a(More)
a a Technologies of energy and energy efficiency industrial research chair (t3e), Abstract In this paper, the thermal efficiency of a solar air collector called unglazed transpired collector (UTC) has been investigated both experimentally and numerically (CFD). Experimental measurements included the following variables: the temperatures of the air entering(More)
In optical tomography, the optical properties of the medium under investigation are obtained through the solution of an inverse problem where some light is injected on a boundary and the measurement of intensity is performed elsewhere on boundary. The properties of interest are the scattering and the absorption coefficients, denoted σ(x) and κ(x) where x(More)
Optical tomography is a technique employed for probing semi-transparent media with the help of light sources [1, 2]. In this method, the spatial distribution of the optical properties inside the probed medium is reconstructed by minimizing an objective function based on the errors between the experimental measurements and the predictions of the light(More)

It is often claimed that the cheapest energy is the one you do not need to produce. Nevertheless, this claim could somehow be unsubstantiated. In this article, the authors try to shed some light on this issue by using the concept of energy return on investment (EROI) as a yardstick. This choice brings semantic issues because in this paper the EROI is used(More)
