Abstract:
The objective of this study is to determine whether the accumulation of dirt on a battle dress garment affects the emissivity of said garment in the thermal radiation spectrum (8-12 μm). This is researched for the purpose of identifying whether there is a need for military units to spend time and resources on keeping battle dresses clean to minimize their thermal signature.To accomplish said objective, two experiments were conducted with the Swedish uniformssystem 90 (battle dress system) to determine change in emissivity due to dirt accumulation in relation to clean garments.

The energy consumption continues to increase as the use of electronics and energy consuming equipment increases. The use of fossil fuels has to be phased out for this to be sustainable in the long run while the use of renewable energy continues to increase. A renewable energy source is solar energy but the production of heat and electricity are today very expensive compared to other energy sources and an important task for the solar energy market to grow is therefore to minimize the production cost of the solar collectors while increasing its efficiency to produce heat and/or electricity.

Två av pelarna avskärmades med förzinkad stålplåt respektive aluminiserad stålplåt och en pelare var helt oskyddad och användes som referens. Mätningar från brandförsöket visar att den maximala ståltemperaturen, i de tre olika pelarna, uppmättes till 580°C, 427°C respektive 1064°C.

The determination of plasma equilibrium profiles is necessary to evaluate the properties of the confinement and to investigate perturbation effects. Optical diagnostics can be used to determine some of these profiles. However, these diagnostics measure all emitted radiation at a solid angle that illuminate each diagnostic channel through a slit. Therefore, the real measured quantity is the emissivity integrated along the line-of-sight and some unfolding procedure, like Abels inversion, is commonly used to recover the emissivity profile.

Abstract:
Les objectifs de cette thèse sont concentrés sur la détermination de l’émissivité (LSE) et de la température de surface (LST) des surfaces terrestres à partir des données de MSG 1 -SEVIRI. Dans un premier temps l’inter-calibrage des canaux infrarouges 4, 9 et 10 de MSG I -SEVIRI avec les canaux de Terra-MODIS est réalisé. Deux méthodes, la méthode «ray-matching» et une méthode basée sur l’équation transfert radiatif ont été appliqués. Les résultats indiquent que les anomalies de calibrage existent entre les canaux de SEVIRI et de MODIS. L’utilisation des résultats obtenus par la méthode basée

Abstract:
Hyperspectral images are made up of energy measurements at different wavelengths of light. The case is considered where these measurements are dependent on temperature, the self-emitted energy (emissivity), and reflected energy (downwelling radiance) from the surroundings. The process where the downwelling radiance is fixed and the temperature and emissivity are estimated is referred to as temperature/emissivity separation. Due to the way these terms mix, for a given set of measurements, there exist many pairs of temperatures and emissivities that satisfy the model. This creates ambiguity in t
