The Master's thesis deals with the determination of mechanical properties of materials used for 3D printing by ALPS ELECTRIC CZECH, s.r.o. (PETG, PLA, ABS, PLA ESD), extended of new materials (ASA, PC / ABS). The prepared test samples, produced by 3D printing technology Fused Deposition Modeling, were analyzed using mechanical tests (tensile test and two hardness tests), surface roughness and dimensional accuracy. Statistical evaluation was performed for individual materials of selected parameters (tensile strength, modulus of elasticity in tension, elongation, Shore hardness, hardness of ball indentation). The conclusion of the thesis is devoted to the comparison of materials by selected parameters and production costs. The additive material PLA Filament Plasty Mladeč proved to be the best with its properties and the second lowest price.

BlueSYSTEM digital inclinometers from WYLER AG, XL-80 laser interferometer from RENISHAW, Ballbar QC20-W from RENISHAW and LaserTRACER self-guiding laser interferometer from ETALON AG were used to measure accuracy. Error of the X straightness in the direction of the Z axis was assessed. The first part of the paper describes the geometric accuracy of the machine, currently available instruments for measuring geometric accuracy and an explanation of straightness. The second part consists of the design of measurements, experiment, evaluation and comparison of results and recommendations for teaching.

Ziel dieser Masterarbeit ist die Untersuchung neuartiger Prägeformkonzepte hinsichtlich ihres Prägeverhaltens. Die Konzepte weisen lokal unterschiedliche Materialeigenschaften auf, die zu einer verbesserten Ausprägung von Karton führen sollen. Die Konzepte sollen anhand der Prägeergebnisse und der Abformgenauigkeit evaluiert werden. Dabei ist ein weiteres Ziel der Arbeit, Methoden zur Quantifizierung der Abformgenauigkeit zu finden. Die Herstellung der Konzepte erfolgt mithilfe eines additiven Fertigungssystems, welches mehrere Materialien in einem Bauvorgang verarbeiten kann. Zur Datengewinnung werden Oberflächenscans der geprägten Kartonproben und Werkzeuge durchgeführt. Auf Grundlage dieser Scans werden drei Methoden zur Ermittlung der Abformgenauigkeit vorgeschlagen. Abschließend werden die Werkzeuge anhand der Prägeergebnisse und der ermittelten Abformgenauigkeit bewertet. Weiterhin werden die vorgeschlagenen Methoden miteinander verglichen und deren Vor- und Nachteile diskutiert.

The concepts have locally different material properties, which should lead to an improved embossing of cardboard. The concepts are to be evaluated on the basis of the embossing results and the impression accuracy. A further aim of the work is to find methods for quantifying the impression accuracy. The concepts will be manufactured using an additive manufacturing system that can process multiple materials in a single build process. Surface scans of the embossed cardboard samples and tools are performed to obtain data. Based on these scans, three methods are proposed to determine the impression accuracy. Finally, the tools are evaluated based on the embossing results and the determined impression accuracy. Furthermore, the proposed methods are compared with each other and their advantages and disadvantages are discussed. This provides information on the conditions under which the use of which method appears to be sensible.:1. Einleitung 2.

Title: Effect of physical load on handgun shooting accuracy. Objective: The aim of this work is to detect and compare the effects of physical activity (in the form of a shuttle run at the limit of 85% SF max.) on the shooting accuracy from a short firearm. Methods: This was an experimental study with an intra-subject design. Thirty randomly assigned police officers at age 35.9 years (SD = 4.5) made 5 shots from a Glock 17 pistol (gen. 3) within 5 seconds in a stable position without support before and after physical activity (shuttle run on length10 m in time until the completion of 85% SF max.) to a fixed target at a distance of 8 meters. Comparison of shooting accuracy from the middle point of impact between interventions (shooting before and after physical activity) was performed by using a paired T-test. The level of statistical significance was set at p ≥ 0.05. Cohen's d was used to determine the magnitude of the strength of the effects. Results: Based on the paired T-test, a statistically significant difference was found in the accuracy of shooting from the middle point of impact without and after physical activity (p = 0.007, d = 0.498). We also consider the deterioration of shooting accuracy after physical exertion by 9 mm from the middle point of impact, which is 21.78%, to be factually...

The aim of my dissertation work was to create an application for pocket PC with operating system Windows Mobile and touch screen, an application that would enable to position the current location of the pocket PC based on the GPS data, on distance measurement between two and more points of which the location is obtained from GPS, and on measurement of territory surface defined by certain number of points obtained from the GPS. The application also enables to display the characteristics of the received GPS signal, information about the number of visible satellites and also information about maximum deviation from positioning. In order to increase the accuracy of the positioning, an averaging function has been implemented. As additional function, a possibility of route location has been created. It measures the passed distance and records some other route characteristics. The application has been successfully tested on pocket PC E-ten M600+ and GPS receiver Navilock but it has been designed with general-purpose and should be compatible with all devices working with operating system Windows Mobile and touch screen. The text section of my dissertation work describes the positioning principle on the basis of satellites with known position, deals with the accuracy of these systems and describes few possibilities how to increase their accuracy. It also discusses the NMEA 0183 Protocol that is used by the majority of GPS modules for communication. The text section also describes several mathematic and cartographic calculations needed for realization of the application. In the end of the text section there is a detailed description of the created application.
