1. Myocardial electromechanical function in long QT syndrome
Sammanfattning : AIM: The aim of this thesis is to assess, in LQTS and according to genotype, the myocardial electromechanical (EM) function response to exercise, its relation to symptoms and its response to b-blocker therapy. To achieve this aim, we conducted 4 studies with the following specific objectives: i. LÄS MER
2. Modeling and simulation of electro-viscoelastic polymers
Sammanfattning : The electroactive polymer materials considered in this work react to electric stimuli by producing deformations. In some cases, the electrically induced deformations are moderate, while in other cases they can be very large and the specimen is stretched to more than twice its original length. LÄS MER
3. Electromechanics of Vertical Axis Wind Turbines
Sammanfattning : Wind power is an established mean of clean energy production and the modern horizontal axis wind turbine has become a common sight. The need for maintenance is high and future wind turbines may need to be improved to enable more remote and offshore locations. LÄS MER
4. Electromechanical Instability in Suspended Nanowire-Based NEMS
Sammanfattning : "Nanoelectromechanical systems'' (NEMS) are a class of nanometer-sized mechanical structures coupled to electronic device of comparable dimensions. Their peculiar features make them interesting both from the technological and fundamental research viewpoints. LÄS MER
5. Electromechanical Phenomena in Superconducting and Normal Nanostructures
Sammanfattning : This thesis summarizes a series of theoretical studies on the electromechanical properties of nanostructures made of superconducting and/or metallic elements. The first part of the work is devoted to the analysis of the interactions between the electronic and mechanical degrees of freedom in suspended nanowires. LÄS MER
