1. Development of a non-destructive field testing method for thermal assessment of district heating pipes
Abstract : The thermal state of a district heating (DH) network governs the heat losses. It is a parameter considered if a change is to be made in the network. Heat losses are costly and economic aspects are important when planning for the maintenance or replacement of DH pipes. READ MORE

2. Modelling and Simulation of Thermal Radiation in Biomass Combustion
Abstract : This thesis presents numerical investigations and simulations of fixed bed combustion of wood, models for predicting thermal radiative properties of particles and gases related to the combustion of wood, and a review of heat load calculations in gas turbines. All subjects have a common factor in thermal radiation. READ MORE

3. Solder Matrix Fiber Composite Thermal Interface Materials
Abstract : Overheating has been a problem for microelectronics devices for decades, and the problem is exacerbated by the continued trend of miniaturization of features and the corresponding increase in power density. Thermal interface materials (TIMs) target one of the main bottlenecks in heat transfer: the interface between two materials, such as between a heat-generating microchip and a heatsink. READ MORE

4. Thermal physiology and metabolism : Interplay between heat generation and energy homeostasis
Abstract : Mammal metabolism is intimately connected to the maintenance of body temperature. While metabolic pathways invariably produce heat as a by-product, the natural heat present in the environment also plays a role in defining the adaptive metabolism and general physiology of an organism.

5. Membrane-based nanocalorimetry for low temperature studies with high resolution and absolute accuracy
Abstract : A differential, membrane-based nanocalorimeter has been designed and constructed for thermal studies of mesoscopic samples at low temperatures. The calorimeter is intended for sample masses from mg to sub-μg and a broad temperature range from above room temperature down to the sub-K region. READ MORE
