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.

Device for monitoring the environmental quality in the car
Doležal, Lukáš ; Szendiuch, Ivan (referee) ; Levek, Vladimír (advisor)
This bachelor's thesis deals with the design of equipment for monitoring the internal environment of the cabin of a passenger car. Equipment suitable for measuring force, atmospheric pressure, humidity, possible noise level and noise level. The main control element of the device is a microcontroller providing communication with the used sensors. The available data is shown on the display and is stored in memory. For communication with a computer, it is possible to use the USB interface using stored data that can be analyzed and processed.

New musical orientations in contemporary liturgical music practice in the Czech republic
Doležal, Lukáš ; Dvořáková, Jiřina (advisor) ; Valášek, Marek (referee)
The work maps the current situation of the use of new musical movements in liturgy in comparison with traditional liturgical music. The work describes the contemporary form of liturgy in the Roman Catholic Church, including the historical context. It also shows the role of music in the liturgy, both new and traditional, based on history and more or less binding rules. The thesis outlines new tendencies in traditional liturgical music and compares it with new - rhythmic liturgical music. Within the rhythmic liturgical music the work describes its roots, sources of inspiration and its origins in the Czech Republic. It also describes its development, presents a selection of the most famous scholars, authors and discusses current and past singers of this new music. The thesis presents new musical approaches in liturgy as a self-valid, widely spread and recognized branch of liturgical music.

Multifunctional building
Doležal, Lukáš ; Utíkal, Aleš (referee) ; Utíkalová, Ivana (advisor)
The subject of the master’s thesis is the project documentation of building work for multifunctional building. The object has three floors. The structural system of the building is bricked. The roof of the building is flat and the terraces are designed as vegetation and walking. On the mainfloor there are situated commercial spaces, building technical facilities and seven residential units. On the second floor there is space for commercial use and seven residential units and on the last floor there is also space for commercial use and one residential units.

Operational efficiency of boilers
Doležal, Lukáš ; Adam, Pavel (referee) ; Počinková, Marcela (advisor)
The topic of this diploma thesis is the operational efficiency of heat sources. The work had several goals. The first was to determine the efficiency of the wood boiler according to available calculation methods and to compare the methods among them. The second was to determine the difference in the performance of the flue gas analyzer and the real calculation. Further, to determine the efficiency of a boiler firing different wood species - spruce and hornbeam based on their properties and elemental composition. Experimental measurement of various operating states of effectiveness took place in an older two-generation family house, which was also the subject of the project part. Due to lack of project documentation, it was necessary to focus and plot the object. Afterwards, the building was thermally inspected and the design of the heating system and the reconstruction of the whole heating system was carried out. The project was developed in two variants for two different heat sources - a heat pump and a solid fuel boiler for heating and water preparation. The thesis deals with the technical report, the conceptual solution of the related professions, the evaluation of the heat source variants and the project documentation.

Heating of residential building with establishment
Doležal, Lukáš ; Horák, Petr (referee) ; Počinková, Marcela (advisor)
The bachelor thesis solves in the computational part design of heating and hot water in historically protected residential building in Chrudim. The theoretical part is about radiators. The building consists of two functional parts.The first part is constituted of a law office with social facilities. The second part consists of a space of an acommodation unit. This part is linked with an attic of the acommodation unit by a two-ply stairs. The heat source for this building is a gas condensing boiler. The heating surface consist of sectional radiators. Part of the work is a budget. The aim of the thesis " Heating of residential building with establishment" is to achieve heat comfort of all occupants.

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)
