16. Remote Monitoring and Automatic Fall Detection for Elderly People at Home
Sammanfattning : Aging population is a one of the key problems for the vast majority of so called "more economically developed countries" (MEDC). The amount of elderly people who suffer from multiple disease and require permanent monitoring of their vital parameters has increased recently resulting in extra healthcare costs. LÄS MER
17. Electrode degradation in proton exchange membrane fuel cells
Sammanfattning : The topic of this thesis is the degradation of fuel cell electrodes in proton exchange membrane fuel cells (PEMFCs). In particular, the degradation associated with localized fuel starvation, which is often encountered during start-ups and shut-downs (SUs/SDs) of PEMFCs. At SU/SD, O2 and H2 usually coexist in the anode compartment. LÄS MER
18. Driving in Virtual Reality : Requirements for automotive research and development
Sammanfattning : In the last decades, there has been a substantial increase in the development of complex active safety systems for automotive vehicles. These systems need to be tested for verification and validation to ensure that the system intervenes in the correct situations using the correct measures. LÄS MER
19. Adhesive wear testing and modelling of tool steels sliding against sheet metals
Sammanfattning : Sheet metal forming is a manufacturing method used because of its versatility. Sheets are plastically deformed by a tool to create a product. A tool is expected to last for several 100,000 forming operations and efforts are made to optimize the tools. A common type of wear referred to as galling is the adhesion of sheet material to the tools. LÄS MER
20. Diagnosing pneumonia in primary care : Aspects of the value of clinical and laboratory findings and the use of chest X-ray
Sammanfattning : It is important to identify patients with pneumonia because it is potentially a serious disease, often of bacterial origin, that should be treated with antibiotics. It is equally important to identify those with acute bronchitis, a self-limiting disease, that should not be treated with antibiotics. LÄS MER
