Analyzing of measured solar spectrum
Štěpánek, Jakub ; Křivík, Petr (referee) ; Vaněk, Jiří (advisor)
This diploma thesis deals with the definition of solar lights for solar purposes and solar simulators. These concepts are presented and described in detail. The theoretical part is described below chapter explaining the possibilities of using solar energy phototherapy. The next section follows the issue of standards and their podnorem AM, describes in detail the direct and diffuse light component. In connection continues with IEC 60904, IEC 60904-3 and IEC 60904-9, differences in purpose and use. The thesis describes the problems of the methods of analysis of the solar spectrum as defined in IEC 60904-9. In the penultimate chapter we discuss all light sources, their properties and uses. They navyzují selected light sources used in this work, as well as descriptions and color filters designed for measurement and subsequent evaluation in the practical part. The last chapter analyzes used measuring instruments, their advantages and disadvantages. In the practical part, we describe a method for measuring real-world light spectra, determining compliance with these spectra spectra AM 1.5 and the necessity to generate data from IEC 60904-3. Another part allows measured data to see in an understandable form and must include an assessment and assignment of the data set into classes according to AM 1.5.

Building survey and evaluating the state of construction
Štěpánek, Jakub ; Komárková, Tereza (referee) ; Heřmánková, Věra (advisor)
This diploma thesis is focused on building survey and evaluating the state of existing constructions. Process of evaluating the state of existing constructions and selected diagnostic methods are described in the theoretical part. The practical part is dealing with performed structural and technical survey of two industrial structures including evaluation of the strength of concrete and verification of the reinforcement. The final part includes assessment of both of the evaluated structures.

Diagnostic methods for the evaluation of the state of timber structures
Štěpánek, Jakub ; Stehlík, Michal (referee) ; Heřmánková, Věra (advisor)
This thesis is dealing with diagnostic methods and methodics of research of timber constructions. Theoretical part is focusing on timber as material for constructions, it's defects, physical and mechanical properties, overview of diagnostic methods and their appropriateness of use. In practical part I am describing performed diagnosis of element of timber construction with focusing on comparing transfer speed of the ultrasonic waves to selected mechanical and physical properties.

Influence of the forest environment under the disparate anthropogenic pressure on insects
Štěpánek, Jakub ; Horák, Jakub (advisor) ; Mladenovič, Strahinja (referee)
Bachelor thesis deals with the evaluation of the influence of environmental variables on the abundance of insects in areas left to spontaneous development. Concretely the location Nature Reserve Forest Polom and National Nature Reserve Žákova hora. In these localities were deployed window traps. Twelve traps at each site. Subsequently were made a total of 4 collections, which were categorized into higher taxonomic groups, the level of orders. Overall were trapped 10 365 individuals divided into 16 orders of insects. With using statistical analysis was evaluated the influence of the environment variables. Environment variables: trunk thickness (cm), distance from the center (m), percentage of spruce (%) had an insignificant effect on the total number of trapped individuals and the number of orders. Statistical significance was demonstrated only for the abundance of the order Hymenoptera in NNR Žákova hora.
