Monument procedure - Measuring during repairs of carpentry structures
Stejskal, David
In this text, the author presents several measurement procedures intended for the repair of valuable carpentry structures. This is not a comletely exhaustive overview of individual options or a comparison of different methods. However, the selected examples summarize the most interesting experiences from twenty years of practice and experiments. For carpenters with varying degrees of expirience, the text tries to offer a number of inspiring insights thet can be used in a creative way even in conditions thet are quite different. Imporved measurement without unnecessary excesses decisively pushes the current limits of technical possibilities, thereby opening th way to more advanced repairs.

Cold spray technology as a tool for repairing of worn parts
Hevessy, Zoltán ; Heczko, Martin (referee) ; Doubrava, Marek (advisor)
Cold spray (CS), also known as cold dynamic gas spraying, is a state-of-the-art process from the thermal spray family, characterized by a combination of low temperature and high velocity of the particles, which makes coatings of sufficient quality for applications in many industries where other processes cannot be used, including repairs of civil and military aircraft and helicopters. The bachelor thesis presents a detailed description of this process, the influence of its parameters on the quality of the coatings, examples of repairs and evaluation of the mechanical and corrosion properties of the repaired parts.

Regression models in survival analysis and reliability
Novák, Petr ; Volf, Petr (advisor) ; Antoch, Jaromír (referee) ; Dohnal, Gejza (referee)
Regression models in survival analysis and reliability Doctoral thesis Petr Novák Charles University in Prague, Faculty of Mathematics and Physics Abstract: In present work we study methods for modeling the dependence of data from sur- vival and reliability setting on available explanatory variables. The first part of the work compares the properties of the Cox proportional hazards model, Aalen additive model and the Accelerated failure model for survival data. We present methods for testing goodness-of-fit based on counting processes and martingale theory, allowing to identify which model fits the data best. The second part focuses on modeling the lifetime of repairable systems. We study the means of incorporating the history of studied devices into the models, including the influence of corrective repairs and preventive maintenance actions. We demonstrate the introduced methods on real applications and study their properties in various situations on simulated data. 1

Rework and Repair Procedures of Selected Components and LED on Various Types of PCBs.
Pospíšil, Tomáš ; Ondřej, Klemš (referee) ; Starý, Jiří (advisor)
This work deals with technology of rework and repairs of electronic soldering assemblies. The work is primarily focused on the rework and repairs of electronic soldering assemblies with the light emitting diode. The theoretical part describes the technological methods of soldering and reworking of electronic assemblies, their diagnostics, evaluation of their influence on reliability and functional properties. The practical part is focused on the real application of technological procedures of rework and repairs, their testing and evaluation. Furthermore there is described and tested the influence of thermal load during soldering on the properties of light emitting diodes.

Porovnání provozně ekonomických parametrů vybraných skupin tahačů návěsů
VÍTOVEC, Drahomír
The aim of this diploma thesis is to find and evaluate decisive operational and economic indicators in a statistically significant group of trucks. They have a high level of chance and are therefore very difficult to determine in advance. These operating and economic indicators included repair and maintenance costs obtained from invoices, financial statements and the results of transport companies' operations. These costs were monitored for the time of operation of these trucks.

Tax aspects of repairs and adjustments of tangible fixed assets
Urban, Marek ; Vančurová, Alena (advisor) ; Finardi, Savina (referee)
The diploma thesis deals with the tax aspects of repairs and technical evaluation of tangible fixed assets, as well as aspects of creation of reserves for repair of tangible assets. The aim of the thesis is to identify problem areas of legal regulation in relation to this area and to propose their solution. The first part of the thesis summarizes the current legal regulations of the investigated area in the Czech Republic. Summary is followed by a case study based on a real tax audit, which demonstrates problem areas of legal regulation. The conclusion of the case study is the comparison of the different options of the additional tax liability and its accessories. In the last part of the thesis are analyzed problematic places of legal regulation, based on a case study, and their solution is proposed.
