Operational Evaluation of the Small Photovoltaic Power Plants Connected to the LV network
Černý, Jaroslav ; Mastný, Petr (referee) ; Orságová, Jaroslava (advisor)
The objective of this thesis is to perform practical measurements of two small photovoltaic power plants, compare the received results with a theoretical calculation, and evaluate how the two differ from each other. Measured data are divided into three groups. The first group evaluates an overall electric power production in the individual months and compares it with the theoretical presumption that is instrumental to a return of investment calculation. The second group shows us a development of electric power production during characteristic days. We can compare how an ideal day from the FVE production point of view looks like, in other words a sunny and clear-sky day, with the opposite case when it is cloudy and raining all day long. Another extreme is a rapid growth or a performance drop, which can happen in a pho-tovoltaic power plant and a time period when this situation can arise. The third group contains statistic data from the electric power production. They are processed in the form of histograms and polygons of production that graphically illustrate production decomposition into the individual months. These data can be instrumental to a decision making about the form of purchase, whether it is economical for us to use the so called green bonus or not.

Compensation program for athletes in Greco-Roman wrestling
Konvičný, Luděk ; Prajerová, Květa (advisor) ; Kamarýtová, Jitka (referee)
Title: Influence of the compensation program for athletes in the Greco-Roman wrestling. Objectives: This diploma thesis concerned with an evaluation of the postural and phasic muscles on the group of ten Greco-Roman wrestling fighters at the age from 16 to 17. Methods: For the assessment of the muscular inequality we used input and output measurements and based on the findings we have chosen the intervention program according to recommended literature. We applied the intervention program to the training units for four months. At the end of the diploma thesis we evaluated the significance of our program using output measurements according to the captured photographs, which we evaluated: fulfilled = 1, failed = 2. We used the Wilcox test to calculate the statistical significance. Results: The worst results were found in the area of postural muscles of m.erector truncata and phasic muscles of m.rhomboideus. The best results were achieved in the area of postural muscles of m.sternocleidomastoideus in a forward bend and in the area of the biceps femoris. The best results of the phasic muscles were achieved in the area of m.rhomboideus. At the end of this thesis it is statistically confirmed that applied intervention program eventually results in the significant difference between the initial and final...
