1. A New Model for Room Acoustic Prediction and Auralization
Sammanfattning : The development of two room acoustic prediction models and auralization methods are described. The first prediction model is a combination of two well known algorithms with some extensions; the image source model and ray-tracing. LÄS MER
2. Efficiency factors for space heating system in buildings
Sammanfattning : The thesis focuses on the efficiency of the space heating system. In particular, the efficiency factors measure the efficiency of thermal zone. The efficiency factors measures how the energy is used in a space heating. LÄS MER
3. Investigations of Flow Patterns in Ventilated Rooms Using Particle Image Velocimetry : Applications in a Scaled Room with Rapidly Varying Inflow and over a Wall-Mounted Radiator
Sammanfattning : This thesis introduces and describes a new experimental setup for examining the effects of pulsating inflow to a ventilated enclosure. The study aimed to test the hypothesis that a pulsating inflow has potential to improve ventilation quality by reducing the stagnation zones through enhanced mixing. LÄS MER
4. Transmission loss of vehicle seals
Sammanfattning : Sound transmission loss of vehicle seals was studied in this thesis. Reverberation room test and semi-anechoic chamber test were respectively studied. LÄS MER
5. Polarized light spectroscopy studies of model membranes and DNA
Sammanfattning : Over the past decades Linear Dichroism (LD) spectroscopy has proven to be a powerful tool for studies of structure and functioning of different cell constituents, including DNA, cell membranes and proteins. Due to structural complexity of cell constituents, the LD studies of biomolecules depend on development of simplified model systems, which can mimic the original structure and functionality of the cell components.
