Hluboké neuronové sítě / Deep Neural Networks

Habrnál, Matěj January 2014 (has links)
The thesis addresses the topic of Deep Neural Networks, in particular the methods regar- ding the field of Deep Learning, which is used to initialize the weight and learning process s itself within Deep Neural Networks. The focus is also put to the basic theory of the classical Neural Networks, which is important to comprehensive understanding of the issue. The aim of this work is to determine the optimal set of optional parameters of the algori- thms on various complexity levels of image recognition tasks through experimenting with created application applying Deep Neural Networks. Furthermore, evaluation and analysis of the results and lessons learned from the experimentation with classical and Deep Neural Networks are integrated in the thesis.

Interpret dynamického programovacího jazyka pro vědecké výpočty / Interpreter of a Dynamic Programming Language for Scientific Computing

Ocelík, Tomáš January 2012 (has links)
The master's thesis deals with design of a dynamic reflective prototype-based language. First, basic principles of this language group are explained and well known representatives are described. Then languages for scientific computing are shortly discussed. Next section of the thesis describes in detail the proposed programming language, its grammar and semantics. Principles of type checking and inheritance are explained. Thesis also demonstrates implementation of basic control structures known from other languages. Next section shows design of virtual machine for the language described before. Section explains used computational model, organization of the object memory and internal representation of important structures of the designed language. Finally, dynamic type checking, compiler and compilation of typical structures to the virtual machine internal code are discussed.

Návrh a realizace malosériové výrobní linky / Design and Implementation of Small-lot Production Line

Šíl, Petr January 2016 (has links)
This Master's Thesis is focused on the design and control of a small-series production line, for the production of segmetal arches and plastic reductions. It is about the conversion from a semi-automatic line to a fully automatic line. The production line consists of an extruder, a cutting unit, a exhaust unit, three pressing machines and a manipulator. Every single machine has a custom control for which was selected a baseplate with microcontroler ATmega 128 and designed powerful part of inputs and outputs. There is a simple communication between the machines. Appropriate elements were used for conversion of every individual part of the production line. The whole system is programmed with software called AVR Studio4.

Výpočetní historie Turingových strojů a jejich generování gramatikami s rozptýleným kontextem / Computational Histories of Turing Machines and Their Generation by Scattered Context Grammars

Kajan, Dušan January 2015 (has links)
The purpose of this thesis is to show a method, that would transform given Turing machine into propagating scattered context grammar, which language contains all valid computational histories of that particular Turing machine. Afterwards this thesis deals with questions arising from existence of such algorithm, especially in regards to the current knowledge about power of propagating scattered context grammars. Practical examples and implementation of proposed algorithm is also part of this thesis.

Řízení balícího stroje s použitím Safety PLC / Control of packaging machine using Safety PLC

Žiak, Martin January 2017 (has links)
This thesis deals with a technology of continuous packaging machine in the beginning from the point of risk assessment and design of necessary measures to reduce the risk as much as it is possible. Here the HRN method was used to quantify every risk factor. Next part documents the implementation of the safety measures and the realization of the safety circuits by using Simatic S7–1500F safety PLC and Shared device functionality. Safety function which is realized in the Sinamics S120 drive is Safe Stop 1. Next, it describes the drive dimensioning and the principle of the drive control. Simotion PLC is discussed in more details and then is used as a motion control master. An approach to the configuration of camming synchronous operation is dealt with in details. Cam design and their realization is documented, too. The thesis also demonstrates the state manager that was implemented in the user program and which is used according to the concept of OMAC state manager. In the end a simple HMI for packaging machine control is described.

Tematizace problému dohledu a moci v kinematografii / The thematization of the issue of surveillance and power in cinematography

Šára, Filip January 2015 (has links)
The goal of this thesis The thematization of the issue of surveillance and power in cinematography is to introduce Michael Focault's theory of power, and add to it with other theories of surveillance with regard to the electronic age (Surveillance studies). Subsequently these theories and hypothesis are applied to qualitative analysis of chosen films with the theme of surveillance. Findings should show the cinematographic reflection of the issue of surveillance and power, de facto depiction of theory and practice of surveillance studies (emphasising the use of power in institutions like prison, hospital, school or working environment, which are heterotopic "other spaces") in live-action movies. The thesis shows development within the past 30 years which took place also due to the existence of internet, which is a kind of institution too. Hypothesis: it is obvious in films with surveillance theme that the concept of the use of power is evolving from "body as a machine" (M. Foucault) to "disappearing bodies" (D. Lyon). The choice of films is analysed only with regard to their depiction of surveillance, is mainly based on the list of movies with surveillance theme constructed by a German theorist D. Kammerer. The goal is also to broaden this list with examples of other films since it should emphasise...

Metody uživatelského hodnocení HMI v prostředí automotive. Případová studie. / HMI user assessment methods in automotive environment. Case study.

Křepelková, Sabina January 2019 (has links)
The thesis focuses on the topic of benefits and limitations of various HMI user assessment methods. In the theoretical part of the thesis there is introduced the HMI theory, summarized HMI user assessment methods, presented knowledge about their utilization and the available tools are mapped. The goal of the practical part is testing of selected HMI user assessment methods related to the requirements of the commercial automotive sector. The result of practical part is a comparison of the strengths and weaknesses of individual approaches and their specifics. The diploma thesis was prepared in accordance with the valid internal regulations of the Charles University and other methodological guidelines and normative documents. Keywords: user experience, UX, usability, user interface, UI, HMI, human-machine interface, automotive, usability evaluation, user assessment, user testing, usability testing

Normalita a normativita / Normality and Normativity

Haloun, Martin January 2017 (has links)
Martin Haloun Normality and Normativity Annotation: The thesis Normality and Normativity is concerned with the problems of the relation of normal and abnormal. The analysis of the expression 'normal' is the introduction of the topic followed by the demonstration that there are multiple meanings of the normal that do not always coincide. During the description of the aspects of norm and normal the fundamental relations between facts and prescriptions will have to be taken into account. The full meaning of the notion normal will be demonstrated on the basis of its relation to the pathological and healthy. A definition of health presented in this thesis, which takes into consideration the specifics of the normal, is based on the works of George Canguilhem and Kurt Goldstein. The crucial moment is the understanding of disease as a reaction of an organism to the limitation of the milieu. An important factor is the introduction of vital normativity that is intrinsic to the living being. This conception opposes the influential conception which identifies the state of health with certain physiological criteria - standards of health - advocated among others by Claude Bernard. At the end of the thesis we will shortly overview the norms as formative aspect in a society. The sociological view of norms that is...
