Forensic ballistics
Votava, Milan ; Štourač, Petr (advisor) ; Musil, Jan (referee)
- 1 - 9. Abstract Forensic ballistics The goal of this thesis is to initiate readers into the branch of criminalistic or forensic ballistics and to its basic terminology. It is not possible to compile this theme at full length, there is no sufficient space for it, therefore I offer professional minimum of criminalistic ballistics. The fundamental purpose of my thesis is to afford the complex view of problems of modern forensic ballistics. The thesis is composed of introduction, six chapters, conclusion and supplements. Introduction defines short acquaintance with theme and with reasons why I decided on the subject of criminalistic ballistics. The following chapter "Historic development of fire arms" features history of weapons or fire arms. The subchapter "Historical development of forensic ballistics" includes the development of the branch abroad and in the territory of late Czechoslovakia too, including the well-known case of manslaughter of countess Windischgrätz. The chapter "Conception of forensic ballistics and its signification" illustrates basic division of criminalistic ballistics, then illustrates objects of investigation and occurrence of ballistics clues. The chapter named "Categories of object in ballistics investigation" is divided into three subchapters and readers can learn basic dividing of...

The influence of high altitude on shooting efficiency of biathletes.
Boudíková, Adéla ; Dovalil, Josef (advisor) ; Pupiš, Martin (referee) ; Ondráček, Jan (referee)
The main purpose was describe the issue of shooting success rate at high altitude (1 500 - 3 000m a. s. l.). Shooting success rate of elite racers was evaluated using analysation of results from individual races at high altitude in the period 1990/1991 - 2013/2014. High altitude had no statistical effect (p<0,05) on shooting success rate of women and men biathletes in the comparision with lowland but it had more negative effect to women shooting success rate than men shooting success rate. Ten national level biathletes were tested in three tests in lowland, four tests at high altitude and five tests in lowland after the return from high altitude. The test included rest shooting in the prone and standing positions and load shooting in both positions which took part of three kilometers running. Twelve days training camp at high altitude did not improve shooting success rate, shooting velocity and running time in the determinated heart rate. Rest shooting and shooting in the prone position did not change statistically during the whole testing period. At high altitude critical days were registered in load shooting in standing position (6th day, p<0,05) and average running time (9th day, p<0,05). Rifle manipulation and shooting are automate motions which are not influenced by high altitude. Most...

Specifics of laser and real firing from a small arms
Didek, Zdeněk ; Michalička, Vladimír (advisor) ; Fiala, Miloš (referee)
Title: Specifics of laser and real firing from a small arms. Goal: The aim of this study to gather information about real and laser shooting from small arms in connection with human physiology and biomechanics. The main benefit of a systematic grasp of the issue as an understanding of comprehensive information. To compare their differences, or to eventually laser-shooting as an instrument for testing soldiers in the Army of the Czech Republic. Methods: Literature search, which deals with the issue of shooting. For the elaboration of this work, the search for study sources was used, followed by their analysis and subsequent search of these obtained study sources. Results: The result of this work is a comprehensive understanding of shooting from real and laser weapons in terms of biomechanics and human physiology and its impact on shooting performance. When comparing real and laser shooting, no significant penetration into the issue was found due to the insufficient number of sources and information about laser shooting. For this reason, a greater representation of the laser weapon cannot be justified in this work at the expense of the real weapon in the Army of the Czech Republic system, even though the use of laser weapons in training is a cheaper financial issue in the long run. Key words: Army,...

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.

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 %.

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.
