Analysis of chip forming mechanism with a high-speed digital camera
Tichý, Vojtěch ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
This thesis covers matters related to high-speed digital cameras and their usage in various spheres of human activities, mainly in research of chip forming. Thesis summarises important knowledge needed for creation of high-speed recordings and choice of suitable lenses. Focus is taken on creation of high-speed recordings of chip forming process in turning operation outside grooving by using of different types of chipformers. Main goal is to verify its functionality in specific value range of feed per revolution.

Methods of Processing of Flat Glass
Tichý, Vojtěch ; Hruška, Pavel (referee) ; Molliková, Eva (advisor)
This "paper" disserts the flat-glass processing methods in the context of history. It outlines the former as well as the current ways of flat-glass production, mentions the possibility of the flat-glass further fabrication using the fritting method in the electric furnace and engages the faults and errors of this technology.

SW for configuration of PLC modems
Tichý, Vojtěch ; Benešl, Tomáš (referee) ; Fiedler, Petr (advisor)
The aim of this bachelor thesis is to design an application for easy configuration of modems, from ModemTec, communicating over power lines. The bachelor's thesis first deals with a brief explanation of the communication over the power line, which will give the reader a general idea of what the application will be used for. Furthermore, to understand the meaning of the individual adjustable parameters of the modem, the serial port is explained, through which the modem will communicate with the parent device that collects data, but also with the computer on which the application will run and with which the modem will be configured. Then, readers are introduced to the design of the user interface and architecture of the application, which includes the basic design principles which the application implementation was based on. The following is a description of the application implementation and the results of ModemTec modem configuration testing. Finally, the achieved results and possibilities for future modification are summarized.

Design of device for determination of air mean temperature in the channel with various crossection
Tichý, Vojtěch ; Musil, Filip (referee) ; Vlach, Radek (advisor)
Diploma thesis was dealing with design of the device for measuring the mean temperature in a channel of any cross-section. First, the theory of heat, heat transfer and fluid flow was summarized. Theory was focused specially on the uneven temperature distribution in the flowing medium. Furthermore, a general overview of commercially used temperature sensors and developed sensors with applicability to the investigated problematics was elaborated. Then, a device for sensing mean temperature in a flow channel for several different diameters has been fully designed and developed. The device included the temperature sensor itself, the necessary measurement electronics and its programming, and a simple measurement data application.

Assessment of river restoration effects based on hydromorphology
Šolc, Jakub ; Matoušková, Milada (advisor) ; Tichý, Vojtěch (referee)
In the field of river restorations, topics being currently discussed are assessing success and quantifying effects that river restoration measures should have. This bachelor thesis deals with an assessment of the river restoration effects based on the hydromorphology. Current knowledge in fields of hydromorphology and fluvial geomorphology are presented in the theoretical part of this thesis. Recent outcomes and methodical procedures that are used to evaluate the effects of river restoration measures are also included. A method was developed based on the theoretical part of this thesis and the method EcoRivHab in order to assess the restoration effects by selected parametres. The method was applied on the restored segment of Litovický stream in Hostivice town in the practical part. The results of the thesis showed what a significant impact the restoration had on Litovický stream (in average +33.74 %). The parameter maximum flow velocity showed the highest effect (+84.9 %). On contrary, the parameter structure of bank vegetation had the only negative effect (-1.8 %). Key words: streams, river restoration, restoration effect, hydromorphology, hydromorphological survey

Assessment and proposal of the river restoration measures in urban and rural landscape
Tichý, Vojtěch ; Matoušková, Milada (advisor) ; Just, Tomáš (referee)
This diploma thesis deals with a proposal and evaluation of stream restoration measures as an effective tool to achieve good ecological status within the requirements of the Water Framework Directive 2000/60/ES. The main aim of this diploma thesis is to propose stream restoration measures at the Lišanský Brook based on evaluation of hydromorphological status, analysis of land-use changes and anthropogenic modification of the river basin, runoff and water quality assessment. Attention is also paid to the evaluation of the restoration measures in the selected localities on Botič and Litovický Brook. The main method used for the design and assessment of stream restoration measures is a field survey using the HEM methodology (Langhammer, 2014). Land-use analysis and stream adjustment analysis are based on available historical maps. Based on the results, Lišanský Brook is evaluated as moderately modified. The entire river basin is an intensively farmed landscape that has been affected by inappropriate anthropogenic modifications. To improve the current unsuitable stream conditions, it would be convenient to apply complete restoration measures on Lišanský Brook. Keywords: Stream, restoration, habitat, diversity, urban area, rural landscape
