2. Study of a Pneumatic Hybrid aided by a FPGA Controlled Free Valve Technology System
Abstract : Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional IC engines could be saved, the fuel economy would improve. READ MORE

5. Studies on Building Air Leakage -a transient pressurisation method, measurements and modelling
Abstract : Airtightness of the building envelope is a key factor for good performance of a building. The main part of this thesis deals with the exploration of a transient pressurisation method for air leakage measurements.In the transient method, an enclosure is pressurised to a desired pressure. The air flow into the enclosure is then stopped. READ MORE
