  2. 1. Generation and Optimization of Motor Behaviors in Real and Simulated Robots

    Author : Krister Wolff; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; behavior-based robotics; bipedal robots; behavior selection; evolutionary robotics; linear genetic programming; autonomous robots;

    Abstract : In this thesis, the problems of generating and optimizing motor behaviors for both simulated and real, physical robots have been investigated, using the paradigms of evolutionary robotics and behavior-based robotics. Specifically, three main topics have been considered: (1) On-line evolutionary optimization of hand-coded gaits for real, physical bipedal robots. READ MORE

  4. 2. Phase transitions in novel superfluids and systems with correlated disorder

    Author : Hannes Meier; Mats Wallin; Asle Sudbø; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; condensed matter physics; phase transitions; critical phenomena; spin models; quantum phase transitions; quantum fluids; superfluidity; superconductivity; disordered systems; Bose glass; dirty bosons; vortex pinning; statistical mechanics; Monte Carlo simulation; Wolff algorithm; classical worm algorithm; Wang-Landau algorithm; Fysik; Physics;

    Abstract : Condensed matter systems undergoing phase transitions rarely allow exact solutions. The presence of disorder renders the situation  even worse but collective Monte Carlo methods and parallel algorithms allow numerical descriptions. READ MORE

  5. 3. Superfluid Phase Transitions in Disordered Systems

    Author : Hannes Meier; Mats Wallin Wallin; Peter Olsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis presents results from large scale Monte Carlo simulations of systems subject to a superfluid phase transition in the presence of disorder. The simulations are performed by state-of-the-art, collective Monte Carlo algorithms treating phase degrees of freedom in effective models with amplitude fluctuations integrated out. READ MORE

  6. 4. The oesophageal route in clinical electrocardiology

    Author : Steen Pehrson; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; oesophageal electrocardiogram; cardiac pacing; Transoesophageal stimulation; arrhythmias; non-invasive electrophysiology; atrial fibrillation; supraventricular tachycardia; Kardiovaskulära systemet;

    Abstract : The subject of this thesis is the clinical use of the oesophageal electrode in electrocardiology. The three areas covered are oesophageal electro- cardiography, the biophysics of transoesophageal atrial stimulation (TAS) and the clinical utility of TAS. The literature is reviewed with respect to these areas. READ MORE
