Studie sanace stokové sítě vybrané části urbanizovaného celku / Study of rehabilitation of the sewer network of selected parts urbanized area

Voldán, Karel January 2018 (has links)
The aim of the diploma thesis was the elaboration of a study of the rehabilitation of the sewerage network in the part of the town of Znojmo. The work is conceived in the form of accompanying and technical reports. The accompanying report contains a brief description of the interest site, basic information about the sewerage system operator and land data. The technical report contains a description of the individual segments of the sewer network, supplemented by photo documentation of the selected faults located on the selected sections. In addition, the evaluation of the structural state of the sub-sections is carried out here. The following subchapter draws up two hydraulic models and their modifications after the recovery of the sewer system. Another part of the technical report describes possible options for remediation technologies. The last part deals with the conclusions and recommendations for the sewer network operator including a briefly outlined economic page in the selection of remediation technology.

Dlouhodobé plány obnovy vodovodních sítí / Long term planning of water distribution network rehabilitation

Hos, Lukáš January 2019 (has links)
This diploma thesis is about long-term rehabilitation planning of water distribution system. First part is about legislative demands on rehabilitation planning in Czech Republic and about methods used abroad to do long-term reahabilitation planning. Second part of thesis is about own created method based on TEA Water (application about condtition assessment of water supply infrastructure). This method is tested on fictional water network and on real water network of Babice nad Svitavou.

Návrh a kontrola parametrů zásobní smyčky linky pro zpracování plechu / Design and examination of parameters of the line stock loop for sheet metal processing

Novák, Tomáš January 2020 (has links)
Master thesis is focused on determination of stress and deformation state of metal sheet in stock loops of non-standard dimension. The main goal was creating numerical model and de-termination of maximal possible stock of metal sheet for all requested parameters. The problem was solved using Finite element methods in the software ANSYS. Results were handed to ŽĎAS, a.s. corporation, where they will be used for design of the lines for metal sheet proces-sing of non-standard dimension. Another goal was estimation, how the residual stress in metal sheet can effect the observed stress state.

Využití umělé inteligence k monitorování stavu obráběcího stroje / Using artificial intelligence to monitor the state of the machine

Popara, Nikola January 2021 (has links)
This thesis is focus on monitoring state of machine parts that are under the most stress. Type of artificial intelligence used in this work is recurrent neural network and its modifications. Chosen type of neural network was used because of the sequential character of used data. This thesis is solving three problems. In first problem algorithm is trying to determine state of mill tool wear using recurrent neural network. Used method for monitoring state is indirect. Second Problem was focused on detecting fault of a bearing and classifying it to specific category. In third problem RNN is used to predict RUL of monitored bearing.

Predikce stavu nabití olověných akumulátorů / State of charge prediction of lead acid batteries

Chochola, Ondřej January 2010 (has links)
The general aim of the thesis is a detailed examination of battery charging condition possibility of lead-acid accumulator with the help of pulse current method. The methodology consists of experimental cell testing by pulse battery charging and pulse battery discharging during a progressive change of charging and discharging current as well as charging and discharging time change. The testing procedure proceeds at a various battery charging condition. Principal aim of this work is to compare final voltage dependencies and to establish the usability of pulse current method to determine battery charging condition.

Vibrodiagnostický systém / Vibrodiagnostic system

Bortlík, Pavel January 2015 (has links)
Thesis discusses bearings failure detection that is manifesting with increased levels of vibration and acoustic emission. The first part of my work gives introduction to common disorders arising on bearings during operation and negative effects on the bearing condition. Further the thesis makes the reader familiar with the terms of vibration and acoustic emission. The work includes a description of available methods for signal evaluation of vibration and acoustic emissions in order to diagnose the state of the bearings in the domains of time and frequency. In the practical part is explained the vibrodiagnostic concept with focus on bearing endurance test. Part of this practical test is a balance sheet for hardware with marginal parametres and a software description. The work is complemented with sorted database of processed topics from the magazine Orbit Bentley Nevada.

Konkurenční strategie firmy Rexport, s.r.o. / Competitive Strategy of Rexport Company

Hrabálek, Ondřej January 2015 (has links)
This thesis analyzes competitive environment in the market segment of board and card games, where the analyzed company is doing business for more than six years already. First, the study defines and assesses current processes and conditions in each part of corporate activities, including in particular retails sales (both e-shopping and brick and mortar shop), publishing house and wholesale of imported products. Through the recent years, the company has undergone extensive and permanent adaption and transformation in order to retain its competitiveness. Competitors on are different regarding the wholesale and retails segment, given that these markets are separated from each other and business conditions vary significantly. Further, paper will provide actual development plans of company for upcoming years and the methods to reach the proposed goals. Finally, the development business plan and methods are to be evaluated, based on competitiveness criteria.

Statické řešení založení novostavby horského hotelu / Static solution of new mountain hotel building foundations

Velecká, Renata January 2014 (has links)
Master's thesis deals with design and static solution of foundation slab of mountain hotel. Two calculation versions are made – simplified („inverse ceiling“) and calculation using software RF-SOILIN. This thesis also includes a comparison of both results. Reinforcement is designed for more accurate internal forces and the assessment of structure is performed according to the 1st limit state of capacity.
