1. 21. Parametric Estimation Techniques for Space-Time Adaptive Processing with Applications for Airborne Bistatic Radar Systems

   Författare :Jacob Klintberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parametric Space-Time Adaptive Processing; Airborne Bistatic Radar Systems;

   Sammanfattning : This thesis considers parametric scenario based methods for Space-Time Adaptive Processing (STAP) in airborne bistatic radar systems. STAP is a multidimensional filtering technique used to mitigate the influence of interference and noise in a target detector. LÄS MER

   Sammanfattning : The worldwide competitive market on metal products with higher quality in industry has increased the need to implement more advanced and controllable quenching techniques in the hardening stage of the heat treatment process. Moreover, sustainability and energy efficiency are key factors to consider in the development of advanced quenching techniques. LÄS MER

4. 23. Towards Clinical Implementation of Dynamic Positron Emission Tomography in Neurodegenerative Diseases

   Författare :My Jonasson; Mark Lubberink; Lieuwe Appel; Jens Sörensen; Michel Koole; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography; PET; Molecular imaging; Quantification; Kinetic modelling; Parametric images; Alzheimer’s disease; Parkinson’s disease; Radiology; Radiologi;

   Sammanfattning : Alzheimer’s disease (AD) and Parkinson’s disease (PD) are the two most common neurodegenerative disorders worldwide. Positron emission tomography (PET), together with suitable biomarkers, can aid in the clin-ical evaluation as well as in research investigations of these diseases. LÄS MER

5. 24. Modelling of Factors Influencing Foot Ankle Responses and Injuries in Car Crashes

   Författare :Niklas Höglund; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mathematical model; foot-ankle injuries; parameter study; toepan intrusion;

   Sammanfattning : Foot and ankle injuries in frontal car collisions are believed to be caused mainly by occupant contact with the floor and toepan, occupant interaction with the pedals, and the lower leg being deformed between the floor and knee bolster. A better understanding of the causes of foot and ankle injuries is required to design cars for improved safety of the legs. LÄS MER

7. 25. Planning for Solar Buildings in Urban Environments

   Författare :Jouri Kanters; Avdelningen för Energi och byggnadsdesign; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; architecture; design tool; design process; solar energy; urban planning; photovoltaics; solar thermal; building integration; density; net zero energy buildings; interviews; parametric studies; action research;

   Sammanfattning : Energy use in buildings accounts for a significant proportion of the total energy use in many countries. While past and current buildings have solely been energy consumers, future buildings will, besides using less energy, also need to produce (part of ) the required energy on site with renewables.
