Design of a photovoltaic power system with battery storage for household purposes in area of Brno-mesto
Vrana, Martin ; Vanýsek, Petr (referee) ; Vaněk, Jiří (advisor)
Táto bakalárska práca sa zameriava na rešerš technológií obsiahnutých v návrhu fotovoltického systému, ako sú solárne panely, nabíjateľné akumulátory, a systémy na premenu elektrickej energie. Následne sú tieto informácie využité na návrh hybridného a sieťového fotovoltického systému pre rodinný dom nachádzajúci sa v lokalite Brno-Mesto. Plán realizácie je nájsť cenovo výhodné riešenie s rozumným časom návratnosti, ktoré prevažne pokryje energetický odber domácnosti. Takisto sú náklady každého zo systémov znížene o dostupné štátne dotácie podľa parametrov každej inštalácie. Sieťový systém je lacnejší ako hybridný systém, pretože systém neobsahuje drahé batérie. Preto má nižšiu dobu návratnosti šiestich rokov, v porovnaní so siedmimi rokmi v prípade hybridného systému. Hybridný systém je výhodný, pretože umožňuje lokálne ukladanie energie a poskytuje záložné napájanie v prípade výpadku prúdu. Dodávateľ elektriny umožňuje uložiť prebytočnú energiu vyrobenú systémami do virtuálnej batérie, z ktorej je možné počas roka čerpať v čase nedostatočnej výroby energie. V kombinácii so súčasnými vysokými cenami energie majú oba systémy relatívne krátke obdobie finančného bodu zvratu v porovnaní so systémami v minulosti. Finálny výber typu inštalovaného systému je na klientovi.

Heat pump in cooperation with PV for family house
Drašar, Vojtěch ; Vrána, Michal (referee) ; Mastný, Petr (advisor)
The bachelor thesis deals with the design of a heat pump in cooperation with a photovoltaic system for a family house. The theoretical part describes the principles of the heat pump and the photovoltaic system. The thesis presents the methods of operation of the heat pump, the principles of building cooling, the connection of the PV system to the grid, or the methods of storing excess energy. In the practical part, the consumption of a typical family house has been determined by means of typical supply diagrams. The consumption is based on hourly statistical values for the year 2021. From the obtained values a pump was designed. Another objective of the work was the placement of photovoltaic panels on the roof. The power plant is considered as a hybrid, in order to maximize the consumption of the energy produced and the use of energy at the point of generation. For this, a battery system was also designed. The work includes an energy and economic evaluation, including the payback of the combination. For the economic evaluation, a subsidy from the New Green Savings 2021+ program was considered. The proposed solution has applications in both renovation and new construction, where the emphasis is on minimizing air pollutants and also the use of ecological resources.

Study of HLA antigens and KIR genes in a donors and recipients of bone marrow
Kroulíková, Zuzana ; Vraná, Milena (advisor) ; Froňková, Eva (referee)
HLA and KIR genes are highly polymorphic regions within the human genome. Protein products of these genes play a critical role in hematopoietic stem cell transplantation. Genetic HLA match is a major barrier to engraftment and influences the outcome of this therapy. Therefore it is necessary to genotype donors and recipients selected for hematopoietic stem cell transplantation. Today HLA-A, HLA-B, HLA-C, HLA-DRB1 and HLA-DQB1 genes are tested by modifications of polymerase chain reaction or by sequence-based typing methods on the level of high- or low-resolution. Donors registered in bone marrow registries are selected on the basis of a 10/10 match. Donors KIR genotype leads to a better outcome, to relapse-free survival and overall survival in treatment of patients with acute myeloid leukemia. A better protection against relapse is achieved by Cen-B/B donor haplotype. Therefore KIR typing by polymerase chain reaction is used and the genotype is compared with the IMGT/KIR database by an online B- content calculator. Donors are divided in groups according to their genotype and their influence on the success of treatment for acute myeloid leukemia. The study of polymorphic systems and the development of genotyping donors and recipients significantly improve the outcome of hematopoietic stem cell...
