3. Tunable Filters based on Ferroelectrics and Semiconductor Varactors
Abstract : Experimental investigation and development of tunable microwave filters, based on single crystals of SrTiO3 (STO) and KTaO3 (KTO), form the main work of this thesis. The dielectric properties of STO and KTO crystals are evaluated experimentally for a wide temperature range, with a DC bias, using parallel-plate resonators with High Temperature Superconductor (HTS) and normal metal (Cu) electrodes.

4. Two experimental studies in foreign language learning/teaching
Abstract : The case for experimental research on the efficiency of methods of foreign language teaching is pleaded. In the first study, the effects of different practice materials on beginners' word-decoding ability in Russian was examined. The Russian words were divided into three categories: 1. The KTO-type.
