1. Mechanical braking systems for trains: A study of temperatures, fatigue and wear by experiments and simulations
Abstract : Increased demand for shorter travel times, higher axle loads, increased volumes and increased punctuality of railway traffic calls for a better design and management of the railway subsystems. The present thesis deals with aspects of mechanical friction brakes, in the form of tread brakes and disc brakes. READ MORE

2. Thermal Capacity of Railway Wheels - Temperatures, residual stresses and fatigue damage with special focus on metro applications
Abstract : Tread (block) braking is still one of the most common braking systems on railway vehicles.The action is carried out by pressing brake blocks against the tread of a wheel, which is also inrolling contact with the rail. READ MORE

3. Frost modelling and pavement temperatures : summer pavement temperaures and frost modelling
Abstract : Three papers form the present thesis. In paper I a numerical model for calculation of surface temperatures on a highway is presented. The model takes all relevant factors into consideration, i.e. READ MORE

4. Improvement of Thermal Comfort in Buildings through Passive Design
Abstract : In hot humid regions the high outdoor temperature has negative effects on the indoor temperature of buildings that are not designed to cope with the local climate. This leads to discomfort for the occupants. READ MORE

5. Nanofiltration at elevated temperatures: Influence of the combined effects of temperature, salts, pH and cleaning
Abstract : The influence of temperature, salts, pH, and various pre-treatments and cleaning on the nanofiltration (NF) performance of thin-film polyamide (PA) composite membranes has been investigated. The change in membrane performance was correlated to membrane swelling or/and electroviscous friction. READ MORE
