Rozvoj instrumentace programu při překladu / Development of Instrumentation during Compilation

Ševčík, Václav January 2020 (has links)
The focus of this master's thesis is on the topic of instrumentation during the compilation process in the LLVM compiler. The tool enables to instrument memory accesses and functions. The instrumentation is realized through adding a novel pass to the LLVM's optimalization phase. Information about variables are managed by the created framework. The framework is linked with the program. The overhead of the instrumentation increases duration of the program by about 14 % in the case of switched off indirect addressing and 23 % in the case of switched on indirect addressing. The main benefit of the work is the possibility of easy instrumentation of the program which can even monitor operation of local variables through indirect addressing) and support multithread programs. The framework is part of Testos's tools where it provides automatic instrumentation in the Spectra tool.

Neeuklidovské vykreslování ve VR / Non-Euclidean Rendering in VR

Bobuľa, Matej January 2021 (has links)
The main goal of this master's thesis is to research different approaches of rendering geometries and spaces in virtual reality. Learn more about the terms, non-Euclidean geometry and non-Euclidean spaces, their origin and different principles used in video game industry to simulate such geometries or spaces. Based on the research, a selection of an optimal API is needed for the implementation of such application. Application is designed to run on desktop computers with Microsoft Windows operating system. Application, in it's core, is a video game and the main goal of the player is to successfully complete each and every level of the game. These levels are designed in a specific way so that they each individually represent some form of non-Euclidean geometry or space.

Štaffa, Jan January 2009 (has links)
This work is focused on single phase inverters, which are used for the conversion of the direct current to the alternating current and are nowdays used especially in systems of back-up power supply. The specific aim of this work is implementation of design hight power circuit of inverter include calculation of control algorithm. It describes the complete solution of power circuit. Next step is a analysis of problems concerning the digital control with help of signal processor which is used for solution of regulator structure. Check of the design and checkout of control algorithm is made in the form of simulation in the MATLAB Simulink. Debugged program algorithm is subsequently implemented into the signal microprocessor. The work results rate estimation functionality of inverter and solution of control algorithm.

Harman, Ján January 2011 (has links)
The aim of my master’s thesis is a system for control of the light intensity. It is electronic equipment which controls the intensity of the light circuits based on settings and input signals. This equipment could work on single-phase systems or multiphase systems. The equipment is controlled by the signal DMX-512 which is a standard for the control of lighting technologies. The set up of this equipment is based on a personal computer or in a limited form by a small connected display.

Analogový vstupní díl pro softwarový přijímač / Front end for software receiver

Slezák, Jakub January 2012 (has links)
This thesis deals with a theoretical analysis of the basic parameters of receivers, input circuit architecture and signal digitization. According to the specified assignment it is outlined block scheme of front end for software receiver with specified components and the total bilance is calculated. Individual parts of the system are designed and realized. This is a set of four input filters for bandwidths: short waves up to 30 MHz, 87,5-108 MHz, 144-148 MHz and 174-230 MHz. The main point of design is a circuit containing a low-noise amplifiers, switches, and two amplifiers with adjustable amplification. Mainly are used integrated circuits from Analog Devices corporation. To control the various switches and adjustable amplifiers was designed a separate panel, which is connected to the main circuit via a cable. In the last phase was the whole system and its components subjected to measurements. Thanks to a number of mounted SMA connectors it is possible to measure different parts of the system and we are able to modify it partially.

Napojení JV obchvatu města Jihlavy-křižovatka silnic I/38 a II/523 / The link-up of the Jihlava city Southeastern by-pass - transport junction of main road I/38 and major road II/523

Kozák, Petr January 2013 (has links)
This diploma work deals with researching study of transport junction of main road I/38 and major road II/523 and than link-up of the proposed Outer ring road (VMO) and Southeastern by-pass (JVO) routes of region capital Jihlava, district of Jihlava, Vysočina region. Road structure will solve designed staged link-up of aboved mentioned roads according to their construction schedule. The design takes into account current roads and completed stages, with respect to minimum costs. Road structure is situated on Czech-Moravian Highlands. Its terrain is hilly, pondy and composed of agricultural parcels. The main purpose of this design is steady link-up of all considered traffic flows in the given locality.

Nekonvenční obvodové prvky pro návrh příčkových filtrů / Unconventional Circuit Elements for Ladder Filter Design

Shaktour, Mahmoud January 2011 (has links)
Kmitočtové filtry jsou lineární elektrické obvody, které jsou využívány v různých oblastech elektroniky. Současně tvoří základní stavební bloky pro analogové zpracování signálů. V poslední dekádě bylo zavedeno množství aktivních stavebních bloků pro analogové zpracování signálů. Stále však existuje potřeba vývoje nových aktivních součástek, které by poskytovaly nové možnosti a lepší parametry. V práci jsou diskutovány různé aspekty obvodů pracujících v napěťovém, proudovém a smíšném módu. Práce reaguje na dnešní potřebu nízkovýkonových a nízkonapěťových aplikací pro přenosné přístroje a mobilní komunikační systémy a na problémy jejich návrhu. Potřeba těchto výkonných nízkonapěťových zařízení je výzvou návrhářů k hledání nových obvodových topologií a nových nízkonapěťových technik. V práci je popsána řada aktivních prvků, jako například operační transkonduktanční zesilovač (OTA), proudový konvejor II. generace (CCII) a CDTA (Current Differencing Transconductance Amplifier). Dále jsou navrženy nové prvky, jako jsou VDTA (Voltage Differencing Transconductance Amplifier) a VDVTA (Voltage Differencing Voltage Transconductance Amplifier). Všechny tyto prvky byly rovněž implementovány pomocí "bulk-driven" techniky CMOS s cílem realizace nízkonapěťových aplikací. Tato práce je rovněž zaměřena na náhrady klasických induktorů syntetickými induktory v pasivních LC příčkových filtrech. Tyto náhrady pak mohou vést k syntéze aktivních filtrů se zajímavými vlastnostmi.

Témata v oblasti centrálního bankovnictví / Topics in central banking

Brož, Václav January 2020 (has links)
This dissertation consists of three research papers dealing with selected issues relevant for central banks after the global financial crisis. The post-crisis world has seen a significant strengthening of the role of central banks with regard to the financial system as well as the real economy. Correspondingly, agendas of some central bankers have grown substantially, encompassing among others monetary policy, financial stability (macro- and microprudential policies) as well as resolution mechanisms. This dissertation thesis reflects the broad focus of some contemporary central banks in three original research articles that concern current unexplored issues for monetary policy and financial stability in the European Union, the Czech Republic, and the United States, potentially bringing policy implications for the relevant authorities. The first article analyzes inflation convergence in the whole European Union (EU) over 1999-2017 and provides comprehensive and robust evidence that the process of inflation convergence among the countries of the EU was not permanently disrupted during the global financial crisis, the European sovereign debt crisis, or the period of zero lower bound interest rates. Specifically, the convergence process did not noticeably weaken after the crisis and the occurrence of...
