16. Advanced Schottky Diode Receiver Front-Ends for Terahertz Applications
Sammanfattning : This thesis treats the development of high frequency circuits for increased functionality of terahertz receiver front-ends based on room temperature Schottky diode technology. This includes the study of novel circuit integration schemes, packaging concepts as well as new measurement and characterisation techniques. LÄS MER
17. Computed Tomography of Acetabular Cup Wear and Effect of Surface Roughness on Wear and Oxidation of UHMWPE Hip Prostheses
Sammanfattning : Aseptic loosening is the most common complication in total hip replacement (5- 10% at 10 years follow up). The magnitude of the problem is illustrated by the fact that about one million hip prostheses are implanted worldwide each year. LÄS MER
18. Optimal Control of Partial Differential Equations in Optimal Design
Sammanfattning : This thesis concerns the approximation of optimally controlled partial differential equations for inverse problems in optimal design. Important examples of such problems are optimal material design and parameter reconstruction. In optimal material design the goal is to construct a material that meets some optimality criterion, e.g. LÄS MER
19. Distributed Signal Processing in Digital Substations : Integrating High Sampling Rate Measurements at the Process-Level
Sammanfattning : Future power systems will be dominated by power electronic (PE) converter connected generation. This trend is primarily driven by the increasing penetration of wind power as well as the increasing integration of photovoltaic (PV) based generation. LÄS MER
20. Characterisation and application of a laser-based hard x-ray source
Sammanfattning : Hard X-rays are generated by focusing 110 fs laser pulses with intensities of about 1017 W·cm-2 onto solid metal targets. Characteristic properties of this X-ray source are the small source size, the short pulse duration and the high peak flux. LÄS MER
