The proposal of a special measuring device to check the chamfer
Novotný, Jan ; Zahálka, Jiří (referee) ; Pernikář, Jiří (advisor)
This diploma thesis consist of basic overview of contact and non-contact measuring methods used at present days across industrial Applications. On the base of given specification for designing of measuring station for measuring chamfer of rotary components The choice and evaluation of theoretical applicability for our application is performed. In the practical part of this diploma thesis The applicability is verified. Performance of these a few exemplary measuring shows possible way of design of constructional solution. All this in a close cooperation with company MESING.

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.

Statistical inspection
Vyškovský, Jaroslav ; Fiala, Alois (referee) ; Pernikář, Jiří (advisor)
This work solving with the statistical inspection verification of big amounts of products imported to Czech Republic. Work it self is designed as general handbook and it will be possible to use it on other products then the model one. This work was elaborated with company which is importing screws for wood industry. We used common standards to define quality requirements of verificated products, and to design statistical inspection plans. The goal of this work is technical and economical evaluation of designed method, which was used on model product.

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.

Calibration management system of measuring machine (CMM)
Lysý, Zbyněk ; Pernikář, Jiří (referee) ; Koška, Petr (advisor)
This diploma thesis with title of „Management of Coordinate Measuring Machine Calibration“ aimed to develop detailed analysis of uncertainties when deploying 3D coordinate measuring machine MicroVu Excel in practice. The analysis was supported by an example of measuring uncertainty calculation. This thesis also discusses the integration of automatic assessment of uncertainties into programming equipment; and creation of methodical calibration process for this kind of machine.

Verification Tightness of Headlamp
Maule, Jiří ; Pernikář, Jiří (referee) ; Osička, Karel (advisor)
The task of my work is to describe and analyse tightness control of front headlights in automotive industry. This work is concerned with theoretical indi-cative allocation according to the light source, development and contruction of headlights in preamble. There is shown the way of disclosing the outflow pres-sure area at loose headlight in next part of this work. It defines the most proba-bly caused reason of untightness with help of Ishikawov diagram. There is also made evaluation of measured values and determined the main cause of un-tightness. At the end there are shown possibilities of statistic´s evaluation of measured values and made changes necesarry for untightness elimination.
