Productivity Analysis of Králík's Bakery Using Time Series
Šimková, Marcela ; Pokorný, Petr (referee) ; Kropáč, Jiří (advisor)
The purpose of this Bachelor thesis is to come up with an in-depth efficiency analysis of Kralik's bakery by means of using time series. The intput data set is entirely based on references which were obtained directly from the bakery. Main intention is therefore concentrated on drawing up an analysis that will be used for prediction of production factors in a future. This will consequently lead to better optimization of production plans.

Theoretical use of nanotechnology for filtration in HVAC systems
Bosák, Jan ; Ell, Jiří (referee) ; Rubina, Aleš (advisor)
Thesis solves problems using the nanotechnology for air filtration in HVAC systems. Main specialization work is air filtration for clean spaces with high classes of purity. For example Hospitals, sophisticated technology service, pharmacy etc. Thesis is devide for three parts. First part contains foundation infromations about theory and making fabrics by nanotechnology. Next I described laws of physics, That were using during the solving filtration´s issues. Goal for second part was making the experiments, which should show abilities and properties nanofilters during the air filtration in real environment HVAC systems. In the end measure part is compare nanofilters with common filters. There is describe nanofiltres behavior and their possibilies during the filtration as well as. In last part I expressed own opinions on air filtration by nanofibers. Opinions were making throught informations, That I found out in the process working on thesis and my experiences in HVAC field. By this facts I did compare for get a better idea. Additionally last part contains summary infomations from previously parts and own vision to development in the future. Goal work isn´t promotion and advertising sorts technologies. Ask is just summary and describe discovered knowledges, considered opinions ensue from measuring, information from the Net and people Who work in nanotechnology field.

Information System Assessment and Proposal for ICT Modification
Černohorský, Michal ; Polák, Petr (referee) ; Koch, Miloš (advisor)
This diploma thesis deals with assessment of the organization's information system. This work is divided into two parts. The first part addresses theoretical description of the information systems and the definition of risks. The second part addresses the objectives of this work, which is the analysis of the current condition of the organization’s information system, identification of risks and suggestions of changes that aims to improve the current state of system and to eliminate discovered risks.

Single-Phase Induction Motor
Vácha, Pavel ; Lapčík, Josef (referee) ; Hájek, Vítězslav (advisor)
The bachelor work is concerned the thesis of a single-phase induction motor that´s perpetually more used in all over the world. Its aim is assembling the information about this type of motor and its calculation. The content of the first part is the theoretical analysis of a single-phase induction motor and acquirement ways of the stroke moment. The practical part contains a basic schema calculation of the single-phase induction motor with an auxiliary phase and a processing demonstrate example of calculation of the single-phase induction motor with concrete parameters along suggested process. In the conclusion there is the evaluation of the whole process.

Single-Phase Induction Motor Calculation
Vácha, Pavel ; Vítek, Ondřej (referee) ; Hájek, Vítězslav (advisor)
The master´s thesis deal with the thesis of a single-phase induction motor that is more and more used all over the world. Its aim is assembling the information about this type of motor and its calculation. The content of the first part is the theoretical analysis of a single-phase induction motor and acquirement ways of the stroke moment. Than the work contains a project of basic schema of the single-phase induction motor with an auxiliary phase. The practical part is devoted to an elaboration of demonstration example of the single-phase induction motor with concrete parameters calculation, its method was projected before. Than there is practising successived measuring on the motor of the same parameters made firm EMP s.r.o. Slavkov by Brno in this part. In the conclusion there is the evaluation of the whole process with reached results.

Reduction of Contact Pairs Friction Losses
Novotný, Marek ; Raffai, Peter (referee) ; Maršálek, Ondřej (advisor)
This bachelor thesis deals with the topic of mechanical efficiency of contact pairs in the crankshaft of the combustion engine. The introductory section focuses on the efficiency of the combustion engine as a whole. In addition, it describes the areas where mechanical losses primarily occur. The following chapters describe mechanism of friction losses, the main factors affecting their amount and the most modern ways to increase mechanical efficiency. In the closing chapter, some basic computing relations, describing the size of mechanical losses are listed. The aim of this thesis is to acquaint the reader with the importance of mechanical efficiency in the area of combustion engines.

Proposal for measures to increase the efficiency of biogas station Obora
NOVÁKOVÁ, Renata
In my thesis, entitled "Proposal for measures to increase the efficiency of biogas station Obora" in the theoretical part deals with factors affecting the efficiency of biogas plants. The practical part focused on the specific biogas plant solves the technological and economic aspects of the station. It also deals with waste heat produced during electricity generation, feedstocks, the use of digestate and biogas station linked with the adjacent farm. The thesis also discusses the problems with which the biogas plant in Obora meets, which have significant impact on the efficiency of the biogas plant.
