1. Environmental Perspectives on Urban Material Stocks used in Construction : Granular Materials
Sammanfattning : The peoples demand of functions and services in cities is the driver for energy and material flows. Most people in the world are now living in urban areas. In order to achieve a sustainable development of cities, both resource use and environmental impact have to be reduced. LÄS MER
2. Heat treatment of Al-Si-Cu-Mg casting alloys
Sammanfattning : Environmental savings can be made by increasing the use of aluminium alloys in the automotive industry as the vehicles can be made lighter. Increasing the knowledge about the heat treatment process is one task in the direction towards this goal. The aim of this work is to investigate and model the heat treatment process for Al-Si casting alloys. LÄS MER
3. Some applications of artificial neural networks in blast furnace operation
Sammanfattning : .... LÄS MER
4. Life of Excitons in Artificial Photosynthetic Antennas
Sammanfattning : Due to the predicted energy crisis when fossil fuels will be exhausted it is important to search for alternative energy sources. Utilizing sunlight via artificial photosynthesis is an interesting possibility. LÄS MER
5. Material distribution-based topology optimization for wave propagation problems
Sammanfattning : This thesis employs material distribution-based topology optimization for wave propagation problems. In the material distribution approach, we define a material indicator function that models the presence and absence of material in a design domain. LÄS MER
