Voltage profile regulation in LV distribution systems by means of OLTC equipped distribution transformer and series transformers based on distributed monitoring data
Hála, Tomáš ; Topolánek, David (referee) ; Drápela, Jiří (advisor)
This diploma thesis discusses two major topics. The first one is the control size of the voltage in LV networks in regard to the increase in distributed generation concered to renewable energy sources. The study contains a review focused on the current state of low voltagegrid followed by a proposal for the solution of the oncoming state. The solution is identified as a deploying OLTC distribution transformer. In the case of more complex topology is deployed a series voltage transformer. Both methods are part of the Smart Grid. The thesis also analyzes the issue of the data measurement and data transmission. The second part of the thesis consists of the description of selected control strategies and their simulations. The design of individual system elements in the PSCAD is described. From these elements, a test network was constructed and tested the individual simulation scenarios.

Monitoring and Measuring of Power Quantities in Waterworks Facilities
Hála, Tomáš ; Pavelka, Tomáš (referee) ; Tichý, Vladimír (referee) ; Radil, Lukáš (advisor)
This Bachelor thesis deals with solution of an exact Smart metering problem. The goal of this thesis is to offer an electrical energy measurement innovation that deals with widespread waterworks objects maintained by Vodárenská a.s. Brno-venkov division. The paper contains an analysis of the current state of reading of electricity meters and the outlook on optimization. The paper also focuses on solving the smart metering problem and contains a description of individual layers of remote reading of electricity meters. The 2nd half of the paper focuses on the specific devices selection and design of data reading topology. An Economical analysis compares costs of project realization with possible savings with the help of chosen methods of financial analysis evaluates the economic effectiveness of an investment.

The Impact of Media on Consumer Behaviour in the Energy Sector
Sedláček, Štěpán ; Hála, Tomáš (referee) ; Langerová, Petra (referee) ; Šedrlová, Magdalena (advisor)
This bachelor thesis deals with the analysis of the aspects that prevent or allow the integration of the principles of social networks into the system of smart meters as well as the study of their potential and possibilities of implementation. The issue of how the future smart grid consumer will benefit from the future smart city grid services are hot topics. Here, a survey is presented that focuses on these aspects. An analysis of the survey results and key messages identifies view of the people on the topic and proposes directions that may be followed when designing applications and services of residential smart city consumers.

Measurement of bone density and its use for determination of biological age, prevention and indication of osteoporosis
Krátká, Jitka ; Ďoubal, Stanislav (advisor) ; Klemera, Petr (referee) ; Hála, Tomáš (referee)
The actual level of factual individual ageing of organism is characterized by biological age. By means of measuring function ability of physiological systems it is possible to evaluate the biological age and use it as an indicator of premature ageing and therefore as an indicator of the risk of getting ill. This study brings an overview of contemporary used, non-standard markers for the measurement of biological age and uncovers the possibility of measurement of biological age (BA) of skeleton and its use in osteoporosis precaution. Inclusion of BA measurement of skeleton into basic screening should bring another perspective how to measure objectively the changes in organism that correspond with ageing. Key words: biological age, osteoporosis, bone ageing, osteodenzitometry

Bisphosphonates in the Treatment of Osteoporosis
Blažková, Šárka ; Vlček, Jiří (advisor) ; Hála, Tomáš (referee)
ZÁVĚR V této práci jsme se pokusili zpracovat problematiku používání alendronátu a risedronátu při léčbě postmenopauzální osteopenie a osteoporózy u pacientek poradenských pracovišť - osteocenter a u pacientek ambulantních lékařů - revmatologů a ortopedů. Z našich výsledků jsme vyvodili následující závěry: Při používání risedronátu, v běžné praxi ve výše uvedených zařízeních, je míra výskytu gastrointestinálních subjektivně vnímaných nežádoucích jevů (GIT sNJ) nižší než u alendronátu. Výskyt sNJ snižuje compliance pacientek k užívání léčiva, ale není hlavním důvodem noncompliance. Některé z pacientek, které přeruší léčbu kvůli výskytu sNJ, tolerují terapii jiným léčivým přípravkem, který obsahuje stejnou nebo odlišnou léčivou látku ze skupiny bisfosfonátů. Je třeba motivovat pacientky k dodržování doporučení k užívání bisfosfonátů (zejména starší pacientky) a pravidelnému užívání léčiva, compliance nedosahuje optimálních hodnot.
