Production Planning with the Support of Information System
Dvořák, Pavel ; Marvánek, Karel (referee) ; Videcká, Zdeňka (advisor)
This thesis deals with adding planning to the current information system as requirement by the company. The theoretical part describes the methodes of information systems for the production plan. These tools are mostly general and trying to cover the entire spectrum of manufacturing processes. The practical part is devoted to implementing of the produciton planning. The modul planning is incorporated into the current information system.The modul planning has been implementing for efficiency of the systemand faster throughput of the orders the company.

Negative Influences of Spindle Vibrations
Dvořák, Pavel ; Huml, Jan (referee) ; Havlíková, Marie (advisor)
This bachelor’s thesis deals with the vibration measuring of the spindle no.1 of the machine tool STRATOS. The vibrations have a fundamental impact both on the machining process and on the observance of a prescribed tolerance. This thesis also treats the accelerometers function principles, namely of the piezoelectric and piezoresistive ones. The aim of the research is to collect the data needed for the proposition of a suitable monitoring mechanism which will monitor the condition of the machining spindle. The thesis also includes a prototypal protocol about the measuring procedure, its achieved results, and graphs. The issue analysis is conceived to the effect that it is applicable for the realization of the monitoring mechanism which will be part of the process and will show the actual state and the condition of the spindle.

Proposal fit stimulative tools
Dvořák, Pavel ; Očková, Pavla (referee) ; Němeček, Petr (advisor)
Purpose of this diploma thesis is proposal of fit stimulative tools. First company Moravia IT, a.s. is introduced along with objectives set for next five years period. Then is high fluctuation in the company chosen as the main problem. The aim is to propose stimuli, which decrease fluctuation. There is an analysis done in the next part, which is focused in negative and positive factors, which influence motivation of employees. The most significant motivation theories are described in theoretical part and their results are also mentioned. Final proposal of stimuli is divided into several parts – employees’ needs identification, definition of new stimuli and selection of suitable stimulative tools. There is made provision for time frame of satisfying employee’s needs in “evaluation” chapter. Also changes in corporate strategy according to the new proposals are demonstrated. At the end of the diploma thesis are suggested particular steps for management, which should have been done to decrease high fluctuation and finally achieve the main objectives of the company.

Automatic recognition of meaning in texts
Jeleček, Jiří ; Dvořák, Pavel (referee) ; Povoda, Lukáš (advisor)
As part of this work it was designed and implemented a system using data mining techniques from the text in order to detect emotions in Czech, English and German language texts. Because the system is built mostly on machine learning techniques, was designed and created training set, which was later used to build the model classifier using the selected algorithms.

Study of rehabilitation of selected part of sewer network
Dvořák, Pavel ; Helcelet, Marek (referee) ; Raclavský, Jaroslav (advisor)
The topic of this thesis is to create a study of the rehabilitation of the sewer network. The sewer system under assessment is located in city Znojmo, specifically Znojmo – city. In this case, rehabilitation is proposed in order to improve the functional operational properties of the sewer network and extend its service life. The work was divided into two basic parts, namely the Accompanying and Summary Technical Report. Three variants of solution were proposed. The first two variants are made as trenchless using a sanitation sleeve in the first one and a short sanitation sleeve in combination with a sanitation sleeve in the second. The third variant is made as an open excavation recovery. A description of the rehabilitation technology was carried out and the facts that each individual Option or what the three Option would bring up were defined. These three variants of the solution are assessed in terms of economic, technical and environmental impact.

Quality and competition.
Dvořák, Pavel ; Toul, Jiří (referee) ; Fiala, Alois (advisor)
This bachelor thesis deals with problems of quality and competitive strength. Here is enlarged the way how to ensure the quality and to satisfy the customer by implementig, following and checking of ISO standards. Satisfaction of the customer brings the potentiality into the company. The only way is to bring up our children for the lifelong learning. Education in languages should be on very high level and languages should be taught even in kindergartens. Crossconnection of the government´s policies in infrastructures and education will have positive influence on our future life, factories will not move to East, they will stay here and employ our people. To be open to innovation and not hesitate to lay resources into it. This is the only way to obtain more effective production. We shouldn´t forget the safety of work and follow the severe laws and standards.The heritage for following generations will depend on our attitude to quality problems and to competitive strength.We cannot think only of short-term profit, but also of the future.The society will be permanently created and developed.The society will be permanently created and developed. We cannot stay on one place in this created system.It is necessary to follow the progress in the world and give priority to new technologies and ensure the prosperity for our descendants.

Brain Tumor Detection and Segmentation in Multisequence MRI
Dvořák, Pavel ; Přibil, Jiří (referee) ; Šprláková-Puková,, Andrea (referee) ; Smékal, Zdeněk (advisor)
Tato práce se zabývá detekcí a segmentací mozkového nádoru v multisekvenčních MR obrazech se zaměřením na gliomy vysokého a nízkého stupně malignity. Jsou zde pro tento účel navrženy tři metody. První metoda se zabývá detekcí prezence částí mozkového nádoru v axiálních a koronárních řezech. Jedná se o algoritmus založený na analýze symetrie při různých rozlišeních obrazu, který byl otestován na T1, T2, T1C a FLAIR obrazech. Druhá metoda se zabývá extrakcí oblasti celého mozkového nádoru, zahrnující oblast jádra tumoru a edému, ve FLAIR a T2 obrazech. Metoda je schopna extrahovat mozkový nádor z 2D i 3D obrazů. Je zde opět využita analýza symetrie, která je následována automatickým stanovením intenzitního prahu z nejvíce asymetrických částí. Třetí metoda je založena na predikci lokální struktury a je schopna segmentovat celou oblast nádoru, jeho jádro i jeho aktivní část. Metoda využívá faktu, že většina lékařských obrazů vykazuje vysokou podobnost intenzit sousedních pixelů a silnou korelaci mezi intenzitami v různých obrazových modalitách. Jedním ze způsobů, jak s touto korelací pracovat a používat ji, je využití lokálních obrazových polí. Podobná korelace existuje také mezi sousedními pixely v anotaci obrazu. Tento příznak byl využit v predikci lokální struktury při lokální anotaci polí. Jako klasifikační algoritmus je v této metodě použita konvoluční neuronová síť vzhledem k její známe schopnosti zacházet s korelací mezi příznaky. Všechny tři metody byly otestovány na veřejné databázi 254 multisekvenčních MR obrazech a byla dosáhnuta přesnost srovnatelná s nejmodernějšími metodami v mnohem kratším výpočetním čase (v řádu sekund při použitý CPU), což poskytuje možnost manuálních úprav při interaktivní segmetaci.
