1. Development and Investigation of Reactivity Measurement Methods in Subcritical Cores
Sammanfattning : Subcriticality measurements during core loading and in future accelerator driven systems have a clear safety relevance. In this thesis two subcriticality methods are treated: the Feynman-alpha and the source modulation method. LÄS MER
2. Measurement of Self-Heating of Biomass Pellets using Isothermal Calorimetry
Sammanfattning : Self-heating in storage facilities of biomass pellet can lead to spontaneous combustion. This has resulted in many fires over the years, causing both financial and environmental losses.In order to assess the risk for spontaneous combustion of biomass pellets during storage, it is important to know how prone the fuel is to self-heating, i.e. LÄS MER
3. On measurement and monitoring of reactivity in subcritical reactor systems
Sammanfattning : Accelerator-driven systems have been proposed for incineration of transuranic elements from spent nuclear fuel. For safe operation of such facilities, a robust method for reactivity monitoring is required. Experience has shown that the performance of reactivity measurement methods in terms of accuracy and applicability is highly system dependent. LÄS MER
4. Description and measurement of sensory symptoms in autism spectrum
Sammanfattning : Unusual responses to sensory stimuli have been reported in nearly all children with autism spectrum conditions (ASC). A few studies on adults indicate that the sensory and perceptual problems persist into adulthood. LÄS MER
5. On measurement, assessment and control of diesel engine noise
Sammanfattning : The thesis comprises six papers with the overall theme of measurement, assessment and control of diesel engine noise, with an emphasize on control. The radiation of noise is shown to be dominated by the low end of the engine sides and by the engine front. LÄS MER
