  2. 1. Dependability analysis of military aircraft fleet performance in a lifecycle perspective

    Author : Jan Block; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Today's highly advanced technological flying platforms, such as aircraft, helicopters and Unmanned Air Vehicles (UAVs), are characterised by a high degree of complexity. Simultaneously, they are used in different operational and mission profiles, and also in multiple operational environments and geographical settings. READ MORE

  4. 2. Acute Occlusion of the Superior Mesenteric Artery : Diagnosis and treatment

    Author : Tomas Block; Stefan Acosta; Martin Björck; Torbjörn Nilsson; Ulf Hedin; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; superior mesenteric artery; acute mesenteric ischemia; acute thrombo-embolic occlusion; computed tomography; vascular surgery; serum biomarkers; microarray; intestinal revascularization; Vascular surgery; Kärlkirurgi; Kirurgi; Surgery;

    Abstract : Acute occlusion of the superior mesenteric artery (SMA) is a condition associated with high mortality and morbidity. The aim of this thesis is to evaluate diagnostic and therapeutic approaches for acute SMA occlusion. READ MORE

  5. 3. Biofilms and microbial barriers in drinking water treatment and distribution

    Author : Jonas Långmark; Gunnar Jacks; Jean Claude Block; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Mikrobiologi; Microbiology; Mikrobiologi;

    Abstract : The primary objective of conventional drinking water treatment and distribution is to deliver to the consumer water that is both aesthetically pleasing and does not constitute a human health risk. To achieve this, water utilities employ a range of physical (i.e. sand and membrane filtration) and chemical (i. READ MORE

  6. 4. Symmetrical FET Modeling

    Author : Ankur Prasad; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; switch model; symmetrical model; nonlinear model; small-signal model; GaAs; Microwave FET; GaN;

    Abstract : This thesis deals with empirical modeling of symmetrical Field-Effect Transistors (FETs). It covers three distinct topics within the areas of modeling and parameter extraction of microwave FETs.First, the symmetry of FET devices is addressed. Such devices are often used in transceivers as a building block for switches. READ MORE

  7. 5. Thermomechanics of block brakes

    Author : Daniel Thuresson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; friction; pin model; contact mechanics; brake; thermo camera; thermomechanical; wear; freight train.; finite element; temperature measurement;

    Abstract : Friction in sliding contacts plays an important role in tribology. Applications can be found in many engineering fields  such as braking of vehicles  in which friction brakes are by far the most common. Thus, an understanding of the mechanisms involved in friction brakes has become more important as the demands on brakes increase. READ MORE
