In the latter aspect significant success has been achieved in decoding biological information formatted as genes and genomes, modeling of biological processes such as metabolic conversion of matter and energy, design and engineering of novel biological parts like synthetic promoters and mutator devices and, finally, development of novel types of bioprocess systems with improved control capability like microfluidics devices. In this work we present the achievements of BioInfoTech Lab in all the above-mentioned applied areas and we elaborate on the future possibilities which the field of Bioengineering provides.

One of the major attributes of the smart grid is to integrate renewable and storage energy resources at the consumption premises. This article presents the methods used in smart home control systems in the integration of renewable energy sources (RES), battery storage, and other electricity sources. The work also investigates the methods for optimization of the house’s consumption in case of integration of heat and cold sources including renewable heat generation (RES). Smart homes save energy and heat, which is why they are eco-friendly and can even be cheaper to live in. In near future the smart houses will present a significant part of the participants at the energy markets, so the optimization methods investigation having economical parameters is also in the scope of this investigation.
