Experimental Verification of Making an Additional Opening to the Reinforced Concrete Walls
Šimek, Ondřej ; Zich, Miloš ; Požár, Michal ; Nečas, Radim
The subject of the article is to present the results of experiments of prefabricated reinforced concrete walls that were loaded prior to the making of an additional opening. These are walls that simulate a regular wall in a wall panel building, into which an additional opening is made. The walls are reinforced with different variants of reinforcement: from simple reinforcement with wire mesh to standard reinforcement around the perimeter, in the lintel and the pillars. The influence of so called "sleeping reinforcement" is studied. This reinforcement is pre-prepared in the panel for the case of making an additional opening. The effect of this reinforcement on the development of cracks and changes in strain on the panel after making the additional opening is studied. Long term monitoring of the panels with newly made opening is also conducted as a part of the experiment.

Analysis of the Equivalent Diagonal Strut Width of Infill Shear Wall with an Opening
Šimek, Ondřej ; Zich, Miloš
The subject of the article is a comparison of behavior of a precast reinforced concrete infill shear walls with an opening with different types of reinforcement. These are the walls that can ensure stiffness of the frame structure against horizontal load. Studied walls with an opening represent cases of how the wall can be reinforced prior to the implementation of an additional opening. The influence of the so called “sleeping reinforcement” is studied. This is a reinforcement that would take effect only after the additional opening has been made. Based on the already published results of the experiment and subsequent verification with numerical models, a parametric study is performed, where the influence of an opening size in these infill shear walls is studied on their load - bearing capacity and stiffness. Lastly, a comparison of the obtained results with available literature is made.

Design of the circle concrete tank
Šimek, Ondřej ; Chalabala, Jiří (referee) ; Klusáček, Ladislav (advisor)
The diploma‘s thesis deals with the design and assessment of prestressed cocrete tank of biogas station at ultimate limit state and also at serviceability limit state, according to ČSN EN 1992-1-1: Design of concrete structures. Specifically, the design of wall of the tank and foundation slab. The text part contains general information on the desing of the structure, static idealization of the structure, type of load and method for calculation of inner forces. Attachments contain drawing documentation and structural analysis, which completes the text part and solves in detail said structure.

Design of equipment of spent nuclear fuel assemblies
Šimek, Ondřej ; Rausch, Ivan (referee) ; Vojáčková, Jitka (advisor)
The diploma thesis aim to the design of equipment for ŠKODA JS a.s., which is part of a new inspection stand (N-SIO). This equipment is an inspection column that provides the possibility to inspect spent fuel assemblies at the operation of the Temelín nuclear power plant. This master thesis is also a summary of the whole design of the new inspection stand and a description of the individual inspection components and devices. One of the parts of the thesis is also a basic strength analysis and a drawing of the main assembly of inspection equipment.

Design of the uderground part of the building
Šimek, Ondřej ; Hrubý, Tomáš (referee) ; Klusáček, Ladislav (advisor)
The bachelor‘s thesis deals with the design and assessment of reinforced concrete monolithic supporting structure of underground garages under apartment building at ultimate limit state and also at serviceability limit state, according to ČSN EN 1992-1-1: Design of concrete structures. Specifically, the design of the ceiling slab, girders, the selected column, the selected part of the wall and foundation under columns. Other parts of the building are not solved in the project. The text part contains general information on the desing of the structure, static idealization of the structure, type of load and method for calculation of inner forces. Attachments contain structural analysis, which completes the text part and solves in detail selected elements of the structure and the drawing documentation.

Processing of a Digital Picture in the Lesson Plan
Šimek, Ondřej ; Lustig, Stanislav (advisor) ; Jiroušková, Ivana (referee)
Tato diplomová práce pojednává o problematice digitálního obrazu. V teoretické části je nejprve specifikován pojem digitální obraz. Dále se práce zabývá digitálním obrazem, jako didaktickou pomůckou a jeho možností při uplatnění ve vzdělávacím procesu. Následující kapitoly jsou zaměřeny na problematiku digitálního obrazu z technického pohledu od principů záznamu až po samotnou prezentaci. Příloha obsahuje ukázky, které nastiňují praktické možnosti využití digitálního obrazu. Součástí práce jsou i elektronické podklady doplňující technicky zaměřenu část. Dohromady s technicky zaměřenou částí by měly tvořit podklad pro výuku. Powered by TCPDF (www.tcpdf.org)

Cooperation of Municipalities in the Region Jilemnicko
Šimek, Oldřich ; Čmejrek, Jaroslav (advisor) ; Kobzev Kotásková, Sylvie (referee)
The Bachelor´s Thesis deals with the topic of horizontal cooperation of the municipalities belonging to the Region Jilemnicko. The region is allocated by the Jilemnice (a municipality with extended powers) district of administration within the Liberec District and it creates a divide with the Hradec Králové District. The thesis analyses and quantifies the cooperation among municipalities in the region according to the forms and ways of cooperating; it researches the intensity with which individual municipalities take part in the various forms of cooperation; it evaluates their contribution as to the creation of development strategies which are important for effective operation
of local government and sustainable regional development.

Regular Expression Based Searching in Text Files
Šimek, Ota ; Samek, Jan (referee) ; Rozman, Jaroslav (advisor)
This paper desribes the design, analysis and implementation of the program, whichis used to search for specific parts of text in text and xml files. To search, you must create a template using two text-matching technigues. These are the regular expressions and XPath expressions. This is desribed in the first chapter. Application allows to process large number of files or files with a high content.

Benchmarks and test facilities of VVER reactors
Šimek, Ondřej ; Foral, Štěpán (referee) ; Vojáčková, Jitka (advisor)
The aim of this bachelor’s thesis is to describe the topic of benchmarks and test facilities for pressurized water reactors of the eastern concept VVER type. The theoretical part introduces the VVER type reactors, their history, the development of separate generations, including fundamental differences and parameters of the VVER type reactors being used so far. Next two chapters of the theoretical part focus on nuclear safety and security, describing the uppermost Czech authorities, which are SÚJB, MAAE and NEA. Furthermore, many terms concerning nuclear safety are explained in these two chapters. The next chapter is focused on deterministic safety analyzes, their classification, methods and purposes. The aim of this part is also to explain the verification and validation of computing codes. The next chapter offers insight into test facilities which are crucial for evaluation and testing of nuclear devices and computing codes. The last chapter of the theoretical part focuses on the VVER type reactor benchmarks. The practical part of this thesis presents the conversion of a single AER Benchmark FCM_001 using neutron physical code PARCS. The results are compared to the results of CRONOS computing code.

Production process monitoring system
Šimek, Ondřej ; Musil, Martin (referee) ; Fiala, Alois (advisor)
This thesis deals with production system monitoring using the SPC method. The reason for the introduction of the SPC system is in an effort to improve the quality consistantcy.This master thesis consists of three parts: Teoretic part: to solve the basic access and process for the aplication of SPC methodics. Practical part: includes the descripton of comtemporary quality control and propositions for the SPC method. Conclution:Conclusions and recommendations are made on the basis of the data evaluation.
