Focus: Solid State Lighting; "Characterisation, Optimisation and Stabilisation of Lighting Quality Aspects of High Quality Hybrid LED Lamps through the Development of Transient LED Models". The adaptive and optimal control factors help to create high quality hybrid LED luminaires that can best satisfy the lighting needs of colour objects. Therefore, high-quality solid-state lighting systems with these hybrid LED lamps are the main goal of the work (https://tuprints.ulb.tu-darmstadt.de/3618/).

Focus: Industrial automation for the mining and petroleum industries, "Research and design of special soft starter for special electric motor in mining industry with high power and low voltage". In mining industry, for the group of low voltage - high current electric motors, there're big problems in the process of starting. Therefore, it is necessary to research an available solution. In the thesis, the research - design - simulation're implemented to find the most appropriate solution for it.

Focus: Industrial Automation, "Research, design and manufacture of automatic humidity, temperature and dew point meter". There's a good relationship between humidity, temperature and dew point. However, if temperature can be measured very accurately, humidity's not easy to measure. Therefore, if the dew point can be determined well, the accurate measurement of humidity can be improved. Therefore, the chilled mirror hygrometer is researched, designed and manufactured to solve the above problems.
