Quantification and improvement in bridge precision measurement deflection
Hvozdenský, Petr ; Suza, Patrik (referee) ; Pernikář, Jiří (advisor)
This thesis deal with improvement in bridge precision measurment deflection for Mostní a silniční Ltd. Its goal is through analysis of process of measurment and factor location, which have fundamental influence on measurment precision. First, theoretic part, represents the company, formulates problems and goals of thesis, history of bridges, world disasters, sort of bridges measurments, bridges evaluation and questions of giant transportation. In second, practical part, problems with measurment and its evaluation are described. Results are evaluated and corrective measures and recommendation are proposed in the final part.

Statisticall Process Control
Neugebauer, Tomáš ; Marková, Petra (referee) ; Pernikář, Jiří (advisor)
This dissertation deals with utilisation of the method SPC in the field of engineering production. The work is outlined as instructions for introduction and usage of SPC in production. The reason for introduction of SPC is the effort to improve the quality constantly. The systematic approach was used for implementation of the very method so that the efficiency of the introduction is as high as possible. The dissertation contains three fundamental parts – theoretical part, suggestion of the process of the solution and practical implementation.

The evaluation of accuracy and eligibility coordinate machines PIONEER DEA
Hrdlička, Martin ; Zahálka, Jiří (referee) ; Pernikář, Jiří (advisor)
This bachelor thesis deals with the accuracy and the qualification of coordinate measuring instrument Pioneer Dea. A target of the thesis is to represent measurement uncertainty using a method of International Vocabulary of Basis and General Terms in Metrology, and for the selected product to determine a qualification of the check process. The evaluation of the qualification of the measuring instrument is performed via method of coefficients cg and cgk. In addition there are calculated measurement uncertainty and via qualification indicator gpp the check process of the selected product is evaluated.

Evaluation of control processes
Šimák, Martin ; Koška, Petr (referee) ; Pernikář, Jiří (advisor)
This bachelor thesis studies the theory of evaluation of control processes. The first part of the thesis discusses about organization of national legislation and metrology legislation. The next part of the study focuses on metrology terms, theory introduction to measurement uncertainty and their expression. The final section of the thesis is devoted to statistic evaluation of processes.

Quality Management system for the calibration of linear gauges
Dobeš, Jan ; Koška, Petr (referee) ; Pernikář, Jiří (advisor)
This bachelor thesis deals with the issues of calibration of gauges. The aim of the thesis is to create detailed calibration procedures and examplary measurements of selected types of length gauges. These gauges are gauge blocks, dial indicator, caliper, micrometer. This measuring was implemented in the calibration laboratory TM Technik s. r. o., where autor could obtain experiences from employees and discuss with them about these topics.

The expression of the accuracy of the gauge and measurement
Svobodová, Helena ; Koška, Petr (referee) ; Pernikář, Jiří (advisor)
The bachelor thesis deals with the issue of measurement, accuracy of measuring instruments and their expressing. It outlines the legislative basis of metrology in the Czech Republic and interprets the definitions of basic terms used in metrology. These definitions are listed in the new edition of International dictionary of metrology (VIM 3:2007). It specifies and exemplifies measurement errors and presents possibilities of their elimination. Further, it describes a simple way of measurement uncertainty determination. The aim of this thesis is to explain the issue in a way that it is understandable and can be applicable for the common metrology practice.
