Integral Identities for Passive Systems and Spherical Waves in Scattering and Antenna Problems
Sum rules and physical limitations within electromagnetic theory and antenna theory have received significant attention in the last few years. However, the derivations are often relying on application specific and sometimes unsupported assumptions, and therefore a mathematically rigorous and …

Sum rules and constraints on passive systems - a general approach and applications to electromagnetic scattering
Physical processes are often modeled as input-output systems. Many such systems obey passivity, which means that power is dissipated in the process. This thesis deals with the inevitable constraints imposed on physical systems due to passivity. A general approach to derive sum rules and physical …

Optimal Port Placement And Automated Robotic Positioning For Instrumented Laparoscopic Biosensors
… However, these biosensors have significant physical limitations that make it difficult to find optimal port locations and place them <em>in vivo</em>. This dissertation explores the application of robotics and virtual/augmented reality to biosensors to enable their optimal use <em>in …

Lebensqualität von Patienten mit koronarer Herzerkrankung in hausärztlicher Betreuung
… %) Questionnaires were analyzed. Differences in physical limitation were dependent on gender and age of patients. Women felt stronger physical limitations, even when their symptoms were rare in the last weeks. 70 –79 year old patients were less affected by physical limitations than younger …

Staff experiences in paediatric trauma services : Exploring perceptions of resilience when dealing with distress
… particularly in considering the professional and physical limitations of the individual. Further research is recommended in further developing a theoretical understanding of resilience in this context. Recommendations for supporting professionals in maintaining and developing resilience are made.

Dynamic optimization of two methods of the long jump
… and angles into consideration to simulate physical limitations. Using a function minimizing optimizer, trajectories were simulated over a range of torque limits and angle penalties. Over the course of 292 simulations, we found that the hitchkick technique improved jump distances more than …

Optimization algorithms in compressive sensing (CS) sparse magnetic resonance imaging (MRI)
… by a slow data acquisition process due to physical limitations. Compressive Sensing (CS) is a recently developed mathematical framework that o ers signi cant bene ts in MRI image speed by reducing the amount of acquired data without degrading the image quality. The process of image …

Exploration of robotic-wheel technology for enhanced urban mobility and city scale omni-directional personal transportation
… freedom, i.e., the ability to exceed one's physical limitations, in essence, to become "more than human" in physical capabilities. This thesis explores novel designs for omni-directional motion in a mobility scooter, car and bus with the aim of increasing personal mobility and freedom. What …

Design and control optimization for high-speed jumping mode Atomic Force Microscope
… between important imaging parameters and physical limitations of the system were established first to identify the aspects of improvement. Two control algorithms to improve the imaging speed and probe sample interaction force for jumping mode atomic force microscopy operation have been …

Symbolic olfactory display
… issues related to such display. I quantify human physical limitations on olfactory input, and conclude that olfactory display must rely on differences between smells, and not differences in intensity of the same smell. I propose a theoretical framework for scent in human-computer interactions, and …
