Slab bridge over the local stream
Doležal, Lukáš ; Svoboda, Adam (referee) ; Požár, Michal (advisor)
The subject of this bachaleor’s thesis is a design road slab bridge with one – spane over the local stream. Span of construction is 19 m. Geometry of the bridge was chosen from 3 studies. Bridge deck is make of prestressed concrete. Calculation of load effect was made in SCIA Engineer 18.1. Slab was structural assessment on ultimate limit state and ultimate serviceability state using MS Excel. Finally was made drawing documentation and vizualization.

Innovation of built-up crankshaft for minibike engines
Doležal, Lukáš ; Mazůrek, Ivan (referee) ; Hanuš, Stanislav (advisor)
The present diploma thesis deals with innovation of built-up crankshaft of Blata minibikes. Minibike is the type of a small two-stroke motorcycle equipped with an internal combustion engine of the volume 40 or 50 cm3. The machine is designed for racing circuits; not only for young riders but also for seniors. The innovation is in the design and verification of pressed connections in the imposition of major pins in the arms of the crankshaft. Pressed connections are designed on the basis of the analysis of force interaction on the crankshaft at maximum revolutions. The proposed solutions are verified by FEM calculations. Based on the results, the best option is selected. For the selected option, the impact of force interaction at maximum machine performance is studied. Finally, on the basis of these facts, designing, technological and economic analysis of feasibility of new production technology is carried out.

Development od individual musicality in church choirs in Telč, in Nová Říše and in Stará Říše
Doležal, Lukáš ; Marešová, Jiřina (advisor) ; Stříteská, Leona (referee)
The work presents the advantages of a person who attends a church music ensemble, in the possibilities of his musical and personal development. These human development possibilities are detailed here for almost all stages of his life: from early school age to old age. The work draws information from total of three sources: theoretical information from professional literature and practical information from a questionnaire survey in the three investigated ensembles and from interviews with their choirmasters. In the practical part, the work focuses on three specific church music ensembles from the region of the author's interest: the Telč Santini Choir, the Staroříšský sbor and the Novoříšská schola. Part of the work is also devoted to the analysis of these bodies based on the data obtained. At the end of the work, the researched advantages in the possibilities of development in the temple music ensemble are placed in a general context and summarized.

Complete implementation of pulse oximeter
Doležal, Lukáš ; Kaller, Ondřej (referee) ; Šotner, Roman (advisor)
This thesis deals with the design of a pulse oximeter. The resulting device allows to measure human blood oxygen saturation and heart rate in a non-invasive way. Easy portability is enabled by battery power supply and the used colour graphical display ensures clear display of the measured data. The paper describes in general terms the principle of pulse oximetry, a description of the chosen electronic components and the firmware developed to ensure the device's operation. Verification of correct operation was performed by comparing the measurements with similar devices available on the market.

ICT literacy of employees as a prerequisite for lifelong learning
DOLEŽAL, Lukáš
This bachelor thesis analyses the ICT literacy of employees of an unnamed Czech company specializing in the sale of building materials. It focuses on their knowledge and skills in spreadsheets, specifically in Microsoft Excel. The main objective of the thesis is to evaluate the current state of ICT literacy of employees and then to propose recommendations that would lead to a possible improvement of the observed state. The theoretical part of the thesis introduces the existing knowledge in the field of corporate education, types of literacy and informs about the possibilities of measuring computer literacy. The practical part provides the basic characteristics of the company under study and then analyses and evaluates the current state of ICT literacy of employees. The findings of this analysis are based on a questionnaire survey of 84 employees, which identifies the actual knowledge and skills used, together with their frequency of use. The main part consists of the results of tests to verify knowledge divided into different areas according to defined requirements. Employees were divided into two performance groups, according to the requirements for their level of knowledge and skills. Following these outputs, three recommendations were proposed that could lead to an increase in the level of ICT literacy of the company's employees and an overall increase in the efficiency of their work.

Personal Timetabling
Doležal, Lukáš ; Barták, Roman (advisor) ; Duša, Vladimír (referee)
Despite all the advancements in Artificial Intelligence, we still do not have a broadly available application for automated scheduling of personal activities. The main difficulty in creating such an application is satisfying user's diverse expectations about time organization. In this study we focused on creating a tool that can help users with organizing their time. We designed a model for describing personal activities with user preferences. We formulated scheduling of personal activities as an optimization problem for which we designed and implemented a solving algorithm, aiming to schedule activities with precision of seconds. We created a prototype of web-calendar application powered by this model and an algorithm which we designed with the focus on ability to clearly display user's time and easily insert activities for automated scheduling. The web application is backed by RESTful API which enables implementing application on various platforms. Powered by TCPDF (www.tcpdf.org)

Multi-span highway bridge
Doležal, Lukáš ; Novák, Richard (referee) ; Koláček, Jan (advisor)
The subject of diploma thesis is designing multi-span highway bridge over Řepovský potok valley, dirt roads and biocorridor. Three variants of bridge were designed and one of them – box girder 10 span bridge, has been chosen. Bridge deck is made from cast in place post tension prestressed beam. Load-bearing structure is concreting step by step on fixed and moving support. Total length of bridge is 560 m. The analysis of structure was projected on several computational models. They have been made in software Midas Civil and SCIA Engineer 18.1. The assessments of ultimate limit state and serviceability limit state were made in all steps of building in longitudinal and cross direction. In the analysis in longitudinal direction is included the time dependent analysis. Structural design was made in software MS Excel according to valid standards. Finally, drawing documentation and visualization were made.

Směrnice o službách a dopady její implementace
Doležal, Lukáš
This bachelor thesis focuses on analysis of legislation regulating free movement of services and Directive on services in the internal market. The thesis is divided into two parts. Theoretical part concentrates on defining the concept of ser-vices and its key features along with analysis of the crucial sections of the Directive 2006/123/EC. Thesis focuses especially on the cross-border service pro-vision and activities related to it. Practical part concerns the comparison of the implementation of the Directive into national legislation in Czech Republic, Slovakia and Poland. Moreover, it examines the effects of this regulation on local markets through the evolution of selected macroeconomic indicators.
