Firearms and ammunitional legal regulation from the perspective of the law of the European Union
Jandásek, Vlastimil ; Staša, Josef (advisor) ; Sharp, Vladimír (referee)
Thesis title: Firearms and ammunition legal regulation from the perspective of the law of the European Union The thesis deals with the legal regulation on firearms and ammunition in the Czech Republic with an emphasis on the new legislation as a result of adoption of the relevant European Union legal framework. The individual principles and legal concepts related to firearms and ammunition are analyzed, the relevant European directive approach is illustrated and novelties, modifications, restrictions as well as mitigations incorporated by the new European legislation are highlighted there. The thesis focuses on civilian acquisition, possession and carrying of firearms from the administrative law point of view. In the first chapter the basic definitions and concepts are defined. The second chapter is dedicated to the European legal regulation, its history and the legal basis on which it now stands. The third chapter deals with the current system of firearms in the Czech Republic. The fourth chapter deals with the effects of the European legal regulation on the legal framework in the Czech Republic and critically evaluates individual partial changes. The fifth chapter deals with the new legal draft. Although it preserves the key conceptual elements of the existing regulation, it can be characterized...

Dynamic Analysis of Selected Firing Mechanisms of Firearms
Mešina, Matej ; Hadaš, Zdeněk (referee) ; Slažanský, Martin (advisor)
This bachelor thesis strives to evaluate the dynamic analysis of firing mechanisms of different types of firearms. In the present research is analyzed the matter of firearms and ammunitions, followed by the description of distribution of firearm mechanisms, as well as the detailed scrutiny of the initiation mechanism. The thesis also marginally explores the testing of primers. The last part of the research documents the possible solutions for the analyzed issues. The practical part of the thesis is devoted to the geometry of firing mechanisms, followed by the description of the physical principles, which are relevant to this matter. Based on the analysis, a theoretical calculation of the initiation energies for all of the analyzed types of firearms is established. Lastly, the calculation of the initiation energy is calculated, and the security in secure firing of the bullet's primer is determined.

Deriving and Application of Analytical Design of Hammerspring in Firearms
Vobejda, Radek ; Polzer, Stanislav (referee) ; Slažanský, Martin (advisor)
The thesis deals with inference of analytic relations for calculation of pressure helical coil spring and considerates usage possibilities of simplified relations. In the thesis there is introduced analytic computation of slightly curvatured rod theory completed by finite element method calculations. The thesis describes two springs of firearm, which weren’t able to achieve required functionality. After this there was created a plan of concept particular spring on the base of derivated relations, which should be able to meet operative conditions.

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 %.

Possibilities of the CAM software PowerMILL 2018 for machining of a component for a firearm
Drmota, Josef ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
The subject of this diploma thesis deals with possibilities of the CAM software PowerMILL 2018 for machining of a component for a firearm. The thesis consists of a research focused on the issue of combined firearms, the specification of the part the thesis deals with and the analysis of the materials used. The practical chapters solve component clamping, tool selection and subsequent elaboration of the NC programs. At the end of the thesis there is shown the simulation of machinig including collison control.

Dynamic Analysis of Selected Firing Mechanisms of Firearms
Hussliková, Veronika ; Hadaš, Zdeněk (referee) ; Slažanský, Martin (advisor)
Bachelor thesis engages in analysis of firing mechanisms of chosen firearms. In introductory part of the thesis, there is a research made which involves gun problems, theoretical basis of gun theory is summarized and detailed description of firing mechanism of some types of guns is given. Alternatives of solution of the set assignment are analyzed at the end of the theoretical introduction. Practical part of the thesis deals with firing mechanisms’ analysis of four different types of firearms and subsequently with theoretical calculation of initiation energy and impact speed of the firing pin. This calculation is in conclusion applied on some specific guns. Final output is the determination of initiation energy, impact speed of the firing pin and safety in safe firing of the bullet's primer.
