The Optimal Accuracy of Measurement Assurance in Accordance with Metrological Confirmation
Frank, Petr ; Kocman, Karel (referee) ; Nenadál, Jaroslav (referee) ; Hruška, Karel (advisor)
This thesis deals with the evaluation of accuracy of measurement and achieving the required accuracy level. This includes global analysis of the uncertainty evaluation, the calibration interval design and the creation of confirmation system. Basis of this work is in identification of all possible problems, which may occur during evaluation of accuracy and achieving the required accuracy level. The analysis is followed by suggested solutions for identified problems. It means namely the selection of probability distribution in case of uncertainty type A, evaluation of degrees of freedom in case of uncertainty type B, nonlinear correlation of input values, evaluation of coverage factor, the choice of method for calibration interval design and the procedure for meeting all metrological confirmation requirements. The last part of the thesis is practical measurement and result evaluation in the field of surge protection devices. This chapter demonstrates conclusions from the syntactical part.

Rámec pro posouzení kvalitativních hledisek informačních systémů
Tamtam, Abdurrzzag Giuma A ; Molnár, Karol (advisor)
Záměrem předložené disertační práce je porozumět tomu, jak investoři v konkrétním společenském kontextu vnímají význam kvality informačních systémů. Ze studia literatury zabývající se přístupy a rámci hodnocení kvality informačních systémů vyplývá, že tato kvalita je obecně hodnocena z hlediska striktního přístupu. V této práci je ukázáno, že kvalitu informačního systému lze smysluplně pochopit použitím interpretačního paradigmatu a že kvalita informačního systému je definována společensky a ovlivňována kontextem tohoto systému. Studie byla zahájena průzkumem dvaceti libyjských organizací. Podrobnější data byla získána z případové studie dvou vybraných libyjských organizací působících ve veřejném sektoru. Při empirické analýze nashromážděných dat bylo využito rámce mnohočetné perspektivy, který zahrnuje hlediska teorie strukturalizace, pojem mnohočetných perspektiv a metodologii měkkých systémů. V práci se dospělo ke zjištění, že: a) kvalita informačních systémů je pojata šíře, než je tomu u tradiční definice kvality, b) mnohočetné perspektivy kvality informačních systémů jsou ovlivněny opakovanou interakcí mezi investorem a institucionálními vlastnostmi kontextu informačního systému a že c) rozdílné hodnoty v kulturním prostředí a vnějším kontextu ovlivňují rozsah působnosti investora a interakce v kontextu informačního systému. Ze závěru práce vyplývá, že společenská skladba mnohočetných perspektiv kvality informačního systému je ovlivněna strukturalizačními procesy mezi investory a vlastnostmi v kontextu informačního systému.

Risk analysis and evaluation in building foundations design
Kalenda, Lukáš ; Bednářová, Bronislava (referee) ; Vymazal, Tomáš (advisor)
This diploma thesis deals with the analysis and evaluation of quality, environmental and safety risks in the design process of the designing the foundations of building. The calculation procedure is shown in the model example. Subsequently, the risk analysis according to DIN EN 31010: 2011 Risk Management - Risk Assessment Techniques is performed. The risk assessment was made by following methods: analysis of the causes and consequences (Ishikawa diagram), the risk matrix and Analysis Failure Modes and Effects (FMEA). Using these methods, the risk were identified and assessed. There are also proposed appropriate measures to reduce the risk value. Comparisons with publications with a similar theme is performed in the final summary.

Measurement of quality of gamma-cameras
Awadová, Thuraya ; Kolář, Radim (referee) ; Drastich, Aleš (advisor)
The topic of this bachelor thesis is the measurement of the gamma cameras’ quality. First, we will focus on the general methodology of imaging in gamma-imaging systems, on the particular types of constructions and technical parameters influencing the resulting imaging quality. In the practical part of the thesis we will pay attention to the methodology of measurement of particular technical parameters within planar or SPECT gamma cameras in a planar mode and their realisation at the Clinic of Nuclear Medicine, Faculty Hospital Brno. The measurement follows the recommendations of the State Office for Nuclear Safety and of the particular gamma camera producer. In conclusion, the stability of a particular quantitative parameter will be evaluated.

Process performance analysis
Řezníčková, Hana ; Koška, Petr (referee) ; Fiala, Alois (advisor)
This master´s thesis deals with analysis current state of the quality management system in the company TRANSELCO CZ s. r. o. For this purpose it was necessary to map the existing processes, examine the documentation, and then perform the internal audit. On the basis of the findings of this analysis was to identify recommendations which should serve to streamline and improve the quality management system and increasing the efficiency of processes.

Analysis of errors in the manufacturing process and their elimination
Slabyhoudek, Jiří ; Fiala, Alois (referee) ; Koška, Petr (advisor)
This thesis deals with the analysis of assembly lines and improve of individual assembly processes to achieve the minimum number of discordant products . It consists of four parts - the first part of this labour deals with general information about the methods of quality control , which are beeing designed to improve actively used . The second part is devoted to the analysis of assembly lines in the company with regard to the financial value of discordant products that are on the line depreciated. Based on the results of determining the most critical line, which is then subjected to a thorough investigation. The third section focuses on selected critical line, you can find here a detailed analysis of discordant products and here is beeing established the root, that causes defects . Based on the information is beeing designed improvement and its application to the assembly line. The fourth section deals with a brief summary of all applicable suggestions for improvement and evaluation of their effectiveness.

Statistical Process Control
Hudečková, Eva ; Fiala, Alois (referee) ; Koška, Petr (advisor)
The master´s thesis deals with the problem of statistical process control. The theoretical part describes the basic quality tools and new quality tools, as a tool for collecting, recording, classifying, and analyzing data. The knowledge gained from the theoretical part are used to describe processes in the company Heat Transfer Systems s.r.o., analyze sticking points, control plans updating and to statistical process control in the organization.
