- The investigation of the influence of lignite composititon on thermal power plant performance and the development of the methods for the selection of replacement coals for slovenian thermal power plants - In order to improve the efficieny and specific consumptions of slovenian power plants the selected measuring were performed. The measuring results were applied for the thermodynamic optimisations of power plant working cycles - Development of computer-aided method for visualization of melted inflow on rotating discs and formation of primary layer for a mineral wool production process. Three EU patents were taken out - Application of the results of transient behaviour of an engine for the development of supporting devices to improve dynamic engine characteristic, such as: in the engine flywheel integrated electric generator/starter or driving motor for Istra-Avtoelektrika development program - Noise reduction of a vacuum cleaner by optimization of performance and noise characteristics of the vacuum cleaner suction unit and housing for LIV and Domel - Detection of cavitation phenomenon in pumps using audible sound for LIV and Iskra-Mehanizmi)
