1. The use of Textiles in an Acoustic Context
Sammanfattning : Working with textiles in an acoustic context gives enormous possibilities to combine the acoustic function of materials with the visual function (aesthetics). Depending on the material choice and the production techniques, textiles may for instance be flexible, stiff, airtight, have high density or high porosity. LÄS MER
2. Characterization of selective solar absorbers : Experimental and theoretical modeling
Sammanfattning : This thesis deals with the preparation, optical characterization and analyses of experimental work and theoretical modeling on selective solar absorbers used in solar thermal collectors. The overall goal has been to obtain efficient absorbers by optimizing the optical properties, and to improve their durability using cost-effective techniques. LÄS MER
3. Solution-Chemically Derived Spectrally Selective Solar Absorbers : With System Perspectives on Solar Heating
Sammanfattning : This thesis consists of two parts, one dominating part concerning spectrally selective solar absorbers and one dealing with thermal solar systems. The appended papers I to VIII concern the solar absorber part, papers dealing with the systems part have not been included in the thesis. LÄS MER
4. Torsional vibration absorbers in heavy-duty truck powertrains
Sammanfattning : The heavy-duty vehicle manufacturers face large challenges when it comes to reducing CO2 emissions from vehicles. The ongoing development of more efficient combustion engines leads to an increase in torsional vibrations. LÄS MER
5. The open absorption system : experimental study of the system and different absorbers
Sammanfattning : .... LÄS MER
