1. Neutrino Oscillations and Charged Higgs Bosons – Experimental Projects for Physics beyond the Standard Model
Abstract : This thesis is based on work done in two different experimental projects. The first project, the Tau RICH, is a previously proposed τ-neutrino appearance experiment for the CERN neutrino beam at the Gran Sasso laboratory in Italy. The proposed experimental concept is based on the use of focusing RICH detectors with liquid radiator (C6F14). READ MORE

3. Large Eddy Simulation of an Oscillating Cylinder
Abstract : In this thesis Large Eddy Simulation of an Oscillating Cylinder is carried out studying the governing flow physics and modeling aspects such as effect of grid resolution and subgrid model. This also involves validation of the predictions with experimental data in terms of Fourier analysis, magnitude and characteristic shape of drag and lift force profiles. READ MORE

4. Sensitivity of Aeroelastic Properties of an Oscillating LPT Cascade
Abstract : Modern turbomachinery design is characterized by a tendency towards thinner, lighter and highly loaded blades, which in turn gives rise to increased sensitivity to flow induced vibration such as flutter. Flutter is a self-excited and self-sustained instability phenomenon that may lead to structural failure due to High Cycle Fatigue (HCF) or material overload. READ MORE

5. Assessment of chest physiotherapy in children
Abstract : Chest physiotherapy (CPT) is used to improve the lung function and blood gas tensions in individuals with respiratory disease. The aim of this thesis was to assess and compare immediate effects of CPT with positive expiratory pressure (PEP) and oscillating PEP (OscPEP) on blood gas tensions in patients with cystic fibrosis (CF), to assess effects of CPT with PEP in severely disabled children, to describe and evaluate a new CPT method for children who cannot co-operate, and to compare obtained results with chest clapping.
