The process of creating healthy food and drinking water typically requires electricity and fuel sources that are not available in rural areas. Africa has an abundance of solar radiation which when properly harnessed creates a viable heating source for cooking food and purifying water. This work will investigate the design of a prototype solar radiation concrete oven for cooking food and treating ...

Imaging Infrared Spectrometer (IIRS) is a Hyperspectral optical imaging instrument which measures the spectra of a scene in high resolution within spectral bands covering Near Infrared (NIR) to Mid Infrared (MIR) regions. Radiation entering the spectrometer assembly governs the temperature of different internal parts and hence plays an important role in determining the desired spectral ...

Finite element modeling of agricultural materials is very often used for describing physical processes. However, exact physical measurements are needed as input parameters for the models. Knowing the driving forces (potentials) during heat and mass transfers is necessary for an accurate model. Water potential gradients as the driving force are used in contrast with the conventional practice ...

High levels of Indoor Air Quality (IAQ) in Operating Theatres (OT) is an important issue in order to contribute in prevention of Surgical Site Infections (SSI). Despite of specific plant layouts are applied for OT ventilation (e.g. unidirectional flow), the effective use conditions can heavily modify the design microclimate and air quality levels. Medical staff presence and movements and sliding ...

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 velocity and temperature. The model has a good agreement with experimental data for the photovoltaic cell ...

In response to continued miniaturization and increased multi-functionality of electronic circuits, the number of integrated circuit (IC) packages on the circuit board continues to increase. As a consequence the operating power density increases and significant increases in the operating temperature of devices result. To maintain operation and long term performance device temperature must be ...

The Solargeotherm project is assessing the possibility of using vertical geothermal probes drilled into a rock mass (bedrock) for storing the thermal energy produced by solar panels and later releasing it. The research project relies on the installation of an experimental system and the use of heat transfer models. The underground device, set up entirely in Paleozoic schist (greenish grey banded ...

INTRODUCTION: Point of care diagnostics aimed at low-resource settings need to be relatively simple, robust and low-cost. The most commonly-used diagnostic platform in these settings is the lateral flow assay (LFA). LFAs are paper-based immunoassays designed to perform on-strip binding with analytes in patient samples in order to generate a visual signal if disease-specific antigen is ...

An important part of the society considers an increased share of renewable energies as an integral part of a strategy towards a sustainable future. As far as heat supply is concerned, this can be achieved using solar thermal collectors, borehole heat exchangers or trough the combustion of biomass. This article shows two applications of two configurations of twisted conduit inside the external ...

During the last decades, mid-IR (3-12µm) laser sources have attracted attention due to their potential applications in different fields like infrared counter-measures (e.g: missile jamming) and remote chemical sensing. In this context, Onera has been working on the development of non-oxid materials and still is developing new crystals that allow to reach higher power and to extend the ...
