Basic Firearms Training for The Police of the Czech Republic
Obermayer, Jan ; Fiala, Miloš (advisor) ; Brych, Jan (referee)
Title: Basic Firearms Training for The Police of the Czech Republic Objectives: The objective of the thesis is to elaborate on basic firearms and shooting technique training within the scope of the basic training course of the Police of the Czech Republic. Methods: The fundamental methods used in the thesis are the data collection method, applied not only for studying literature, but also in the subsequent selection of professional experience and knowledge. Another method is the analysis method, used for expert evaluation. Another basic scientific method is applied, for the purpose of describing basic methodological and tactical procedures and also creating a set of preparatory training sessions. The method is referred to as information synthesis. Results: The output of the thesis is creating a complex view of the issue concerning firearms training for the Police of the Czech Republic according to today's methodology, tasks and objectives laid on this education course. Despite the curriculum of the firearms training being the same for several years, there is a definite improvement and effort to draw the training closer to actual situations and operations. I find that developing methodological guides and professional publications, not only from police shooting, but also practical and defense...

Suggestions for changes in the production of a part "revolver trigger"
Jiráček, Jan ; Chladil, Josef (referee) ; Kalivoda, Milan (advisor)
The study deals with production technology of “revolver trigger“. Final assembly is short firearm ALFA Steel and its model series of ALFA-PROJ, Ltd company. Introduction submits an explanation of trigger technology suitability. The following analysis describes current manufacturing process, which has manufacturing inaccuracy problem. Furthermore rootcause of manufacturing inaccuracy was determined and analysis of suggestions for changes (including modifications of technological process) was realized. Based on experiment dimensions were measured on provided samples of suggest production in Technical Control Department. Dimensions of triggers manufactured by current production were verified during the experiment too. Results were compared according to the rejects of production. In the final phase of the study manufacturing labor costs were compared for the one piece of trigger with the new suggested technology.

Firearm Type Identification in an Image
Čech, Ondřej ; Drahanský, Martin (referee) ; Dvořák, Michal (advisor)
Main goal of this work is to design, implement and test an approach for classifying firearms in an image into categories with short and long fireams, and then with single shot, multi-barreled, repeating and semi-automatic/automatic firearms. This problem was solved using SVM classifier together with Harris corner detector, FREAK descriptor and Bag of Words method. Accuracy of final program is up to 13,3 %.

CAD design of the Walther PPS M2 laser sight housing
Macků, Veronika ; Hejtmánek, Petr (referee) ; Vančura, Jan (advisor)
The aim of this thesis is to create a housing for a laser-sight for a Walther PPS M2 pistol with the aid of reverse engineering methods. The first part is a research about laser-sights. The second part contains contemplation about the problem, mainly the restrictions brought on by the design of the Walther pistol and of the energy source of laser-sight Streamlight TLR-6, as well as the chosen production method of the housing, which is 3D printing. The main part describes the acquirement of input data via scanning the body of the Walther pistol and the housing of TLR-6, the making of the CAD design of the housing, the printing of a prototype with a 3D printer and the consequent correction of the CAD model on the basis of analysis of the prototype.

Maintenance and service SW for weapon calibration
Fedor, Denis ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
This thesis deals with virtual weapon simulator SAVIT for armed forces training. Using the example of training weapon MP5 the electrical structure of the device itself is described, followed by the description of communication protocol CANaerospace and USB. The thesis contains the list of parameters of the individual training weapons which are eligible to view in their service program. It also describes graphical user interface of the service program and important parts of its implementation. This thesis does not omit description of the communication between service program and training weapon. In the end it also contains the description of program testing and evaluation of the results of this thesis.

Production technology of part barrel shroud
Jiráček, Jan ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
The study deals with technology of "sport steel" barrel shroud part made from a rod semi-product. It makes part of final assembly of a short firearm - ALFA steel revolver, Sport model, of ALFA - PROJ, Ltd. Czech company. Recherche introduction explains basic tooling (its history, tool material's development, milling and hole machining). Furthermore, it is submits an explanation to general arms division and analysis of barrel shroud technology suitability. The following technology process analysis describes the barrel shroud manufacturing process in the aforementioned company. Study's last part shows possible suggestions for manufacturing improvements and rationalizing measures.

Determination of Gun Type and Position in Image Scene
Kolcún, Róbert ; Goldmann, Tomáš (referee) ; Drahanský, Martin (advisor)
The main goal of this work is to design an approach for classifying guns into two categories, with short and long weapons, and determining a position of guns in the image scene. This problem was solved using the classical approach as K-Nearest-Neighbour and SVM classification and using convolutional neural networks. In this work was made a comparison of these approaches with a resulting accuracy up to 90%. With the results of this work, it is possible to choose a right approach to this problem.
