    Názov práce: Multiplatformní prostředí pro vývoj mobilních her Autor: Ivan Vacula Katedra: Katedra softwarového inženýrství Vedúci diplomovej práce: RNDr. David Bednárek, Ph.D. E-mail vedúceho: [email protected] Abstrakt: Inteligentné mobilné zariadenia sú v dnešnej dobe čoraz viac obľúbené. Spolu s ich rozšírením prichádza aj problém s vývojom aplikácií na niekoľko platforiem súčasne. Jednotlivé mobilné operačné systémy ako aj samotné zariadenia sa od seba zásadne líšia a pre multiplatformný vývoj je potrebný systém abstrahujúci rozdiely medzi nimi. Ešte o niečo zložitejšia je situácia pri vývoji hier, ktoré vyžadujú čo najlepšie využitie prostriedkov zariadenia, s ohľadom na rýchlosť, odozvu, grafické spracovanie a podobne. Cieľom tejto práce je porovnať existujúce riešenia pre multiplatformný vývoj mobilných hier, potom navrhnúť a implementovať vlastný systém. Systém musí zabezpečiť jednotný vývoj hier pre niekoľko operačných systémov zároveň. Súčasťou práce je implementácia systému pre dve diametrálne odlišné mobilné platformy a implementácia demonštračnej hry.

But there comes a problem with their expansion as well. Mobile operating systems differ from each other, as do mobile devices themselves, so development across multiple platforms is not simple. Situation is even worse when it comes to games. These need to use limited resources of a mobile device as much as possible, taking into account quick response to user actions, graphical execution et cetera. The first goal of this thesis is to compare existing solutions for multi-platform mobile game development. The second goal is to design a new system. This system must ensure targeting of multiple platforms during mobile game development. Included in this thesis is implementation of the system on two vastly different operating systems as well as implementation of a demonstration game.

    Study of heat transport throw bulk materials with electric conductive aditive

    No full text
    Bachelor thesis is focused on the study of heat transport in bulk materials made from PLA (polylactic acid) filaments by 3D printing. For subsequent applications it is important to know the electrical, dielectric and thermal parameters of materials with different dyes, pigments and electrically conductive additives. The aim of this work is mainly to study the thermal properties of the series and the influence of additives on these properties. The main focus is to study the thermal properties of the samples. In the theoretical part, different 3D printing methods are mentioned, the methods of measuring the thermal properties, and finally the properties of the lactic acid polymer are described. The experimental part is devoted to the description of the process of 3D printing samples for measurements and then the method of measuring the thermal properties of the printed samples is described. For samples with electrically conductive admixtures, the thermal conductivity was found to be in the range of (0,217–0,292) W/m/K and the specific heat capacity was found to be (382,2–1 007,2) J/kg/K. The electrically conductive materials (PLA with metallic admixtures) were found to have a very good thermal conductivity and a smaller specific heat capacity, while the materials with admixtures of dyes and pigments showed a smaller thermal conductivity and a larger specific heat capacity

    Lubricant Gap Shape Optimization of the Hydrodynamic Thrust Bearing

    The objective of this Master's thesis is to find, using genetic algorithm (GA), an optimal profile for lubricating gap of a thrust bearing of a turbocharger. Compared to the analytical profile, the optimal profile is expected to have minimized friction for an equivalent load capacity. Friction minimization is one way to increase the efficiency of the thrust bearing; it reduces the friction losses in the bearing. An initial problem was given: a thrust bearing with Load capacity 1000 N, inner and outer radii of 30mm and 60mm respectively, rotor speed of 45000 rpm and angle of running surface of 0.500.5^0. Lubricant properties were also provided for the initial problem: oil density of 840kg/m3 840 kg/m^3, dynamic viscosity (η)(\eta) of 0.01 Pa.s With this data, the numerical solution of the Reynolds equation was computed using MATLAB. To obtain more information, the minimum lubricating gap thickness was also computed using MATLAB. With this information, the shape of the analytical profile, and its characteristics were found. The analytical profile was then used a guide to create a general profile. The general profile thus obtained is then optimized using GA. The characteristics of the generated profile is then computed and compared to that of the analytical profile

    Observing ultra-high energy cosmic rays with prototypes of the Fluorescence detector Array of Single-pixel Telescopes (FAST) in both hemispheres

    The origin and nature of ultra-high energy cosmic rays (UHECRs) are hot topics in the astroparticle physics community. The Fluorescence detector Array of Single-pixel Telescopes (FAST) is a design for a next-generation ground-based UHECR observatory, addressing the requirements for a large-area, low-cost detector suitable for measuring the properties of the highest energy cosmic rays with an unprecedented aperture. We have developed a full-scale prototype consisting of four 200 mm photomultiplier tubes at the focus of a segmented mirror of 1.6 m in diameter. Over the last three years, we have installed three prototypes at the Telescope Array Experiment in Utah, USA. These telescopes have been steadily taking data since installation. We report on preliminary results of the full-scale FAST prototypes, including measurements of UHECRs, and distant ultraviolet lasers used to study the atmospheric transparency. Furthermore, we discuss the installation of an additional identical FAST prototype at the Pierre Auger Observatory in Argentina. Possible benefits to the Telescope Array Experiment and the Pierre Auger Observatory include a comparison of the transparency of the atmosphere above both experiments, a study of the systematic uncertainty associated with their existing fluorescence detectors, and a cross-calibration of their energy and Xmax scales

    Consensus Document on Intermittent Claudication from the Central European Vascular Forum (C.E.V.F.) - 3rd revision (2013) with the sharing of the Mediterranean League of Angiology and Vascular Surgery, and the North Africa and Middle East Chapter of International Union of Angiology.

    This paper is the review of the Consensus Document on Intermittent Claudication of the Central European Vascular Forum (CEVF), published in 2008, and and shared with the North Africa and Middle East Chapter of International Union of Angiology and the Mediterranean League of Angiology and Vascular Surgery. The Document presents suggestions for general practitioners and vascular specialists for more precise and appropriate management of PAD, particularly of intermittent claudication, and underlines the investigations that should be required by GPs and what the GP should expect from the vascular specialist (angiologist, vascular surgeon). The idea of the Faculty is to produce a short document, which is an easy reference in daily clinical practice, both for the GPs and vascular specialists

    Comparison of MOSFET Gate Waffle Patterns Based on Specific On-Resistance

    This article describes waffle power MOSFET segmentation and defines its analytic models. Although waffle gate pattern is well-known architecture for effective channel scaling without requirements on process modification, until today no precise model considering segmentation of MOSFETs with waffle gate patterns, due to bulk connections, has been proposed. Two different MOSFET topologies with gate waffle patterns have been investigated and compared with the same on-resistance of a standard MOSFET with finger gate pattern. The first one with diagonal metal interconnections allows reaching more than 40% area reduction. The second MOSFET with the simpler orthogonal metal interconnections allows saving more than 20% area. Moreover, new models defining conditions where segmented power MOSFETs with waffle gate patterns occupy less area than the standard MOSFET with finger gate pattern, have been introduced

    An automated all-sky atmospheric monitoring camera for a next-generation ultrahigh-energy cosmic-ray observatory

    We have developed a fully-automated instrument (FASCam — Fast All Sky Camera) designed to capture night all-sky images and analyse cloudiness and coarse atmospheric properties for a proposed next-generation ultrahigh energy cosmic ray observatory, called the Fluorescence detector Array of Single-pixel Telescopes (FAST). FASCam has a 360° × 90° (azimuth and elevation) field of view and is equipped with a series of photometric Johnson-Cousins filters (BVR) and an Ultra-violet (UV) filter. The camera is installed on the top of one of the three FAST prototype telescope buildings located in central Utah, U.S.A. . An online analysis of the images provides real time cloud coverage maps and coarse atmospheric extinction measurements and a night sky background estimate in the field of view of the FAST fluorescence telescopes. The result serves as an input parameter for the operation of the telescopes and avoids unnecessary data taking in the case of clouds covering the field of view of the telescopes, high atmospheric extinction, or high night sky background
