1. 1. Offshore deployments of marine energy converters

   Författare :Maria Angeliki Chatzigiannakou; Irina Temiz; Mats Leijon; Tony Lewis; Uppsala universitet; []
   Nyckelord :offshore deployments; risk assessment; wave energy converter installation; marine current energy converter installation; economic efficiency; time efficiency; offshore operations; point absorber; hydrodynamic analysis; slack sling criterion; hoisting system failure.;

   Sammanfattning : The depletion warning of non-renewable resources, such as gas, coal and oil, and the imminent effects of climate change turned the attention to clean and fossil fuel-free generated electricity. University research groups worldwide are studying solar, wind, geothermal, biomass and ocean energy harvesting. LÄS MER

   Sammanfattning : This doctoral thesis consists of a literature review, presented in two papers, and another six papers describing experimental studies of the influence of different kinds of wax and polyphosporic acid on bitumen and asphalt concrete mixture properties. The literature review should give an extensive description of the field of knowledge concerning wax in bitumen. LÄS MER

4. 3. Effects of ageing on contractility and myosin composition of rat and man skeletal muscles and muscle cells : with special reference to muscle adaptability

   Författare :Xiaopeng Li; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :ageing; hyperthyroidism; skeletal muscle; single skinned fibre; isometric twitch; slack test; shortening velociy; electrophoresis; myosin isoform; immunocytochemistry;

   Sammanfattning : The aims of this thesis were to characterize the effects of ageing on the contractile and biochemical properties of fast- and slow-twitch skeletal muscles at the whole muscle and single fibre level in an attempt to improve our understanding of the mechanisms underlying the age-related impairments of muscle fibres. Specific interest was in the adaptability of skeletal muscle and the regulation of speed of shortening at single-cell level in the rat and man. LÄS MER

5. 4. Enhancing the Performance of Distributed Real-time Systems

   Författare :Hoai Hoang; Magnus Jonsson; Bertil Svensson; Luís Almeida; Högskolan i Halmstad; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Switched Ethernet; Real-Time Communication; EDF scheduling; Reducation of delay and jitter; Computer science; Datalogi;

   Sammanfattning : Advanced embedded systems can consist of many sensors, actuators and processors that are deployed on one or several boards, while having a demand of interacting with each other and sharing resources. Communication between different components usually has strict timing constraints. LÄS MER
