Výroba dílců pro okenní kování / Production of parts for window fittings

Havliš, Lukáš January 2012 (has links)
This project submits a proposal for manufacturing technology of casement and frame window hardware base, made of 11343.23 steel 2,5 mm in thickness and with 15000 pieces annual production volume. The components form an integral part of a window hardware arrest mechanism. From potential variants of manufacturing, the technology of stamping and bending, with the use of a combined tool, was chosen. A bibliographic search examining these technologies was made and the machine LE 250 with nominal forming force 2 500kN was selected. The project comprises structural and technological calculations, including the combined tool design. In the economical part of the project, the product prices were quoted and the break-even point was determined. The break-even point is broken as soon as 13 046 pieces are manufactured.

Příprava grafenových vrstev pokrytých Ga atomy a charakterizace jejich elektrických vlastností / The preparation of graphene layers modified by Ga atoms and characterisation of their electrical properties

Piastek, Jakub January 2015 (has links)
This master's thesis deals with the study of electric properties of graphene layers covered by Ga atoms in UHV conditions. The substrates were prepared by using laser litography and the graphene layer was prepared by using chemical vapor deposition (CVD). Dependence of Dirac point location on gallium atoms deposition time and influence of electrical properties of graphene on hydrogen atoms deposition time were studied. Experimental results and their evaluation are discussed.

Kritické parametry pro bezdrátové sítě WiFi a WiMAX / Critical Parameters for Wireless Networks WiFi and WiMAX

Grenar, Milan January 2015 (has links)
My thesis will be aimed at problems of wireless networks WiFi and WiMAX. A modelling of network will be put into effect onto which the measurement will be implemented and the impacts of network load on the data transfer Quality of Service (QoS) will be examined with aiming at VoIP. On this network model a power failure will be simulated and the impacts of this failure after restoring the power supply will be monitored. The aim of this thesis is to check the rate of network throughput while preserving a providing service quality and to suggest an economica1ly acceptable solution of the problems relating to feeding tension outage of the access point (AP) for a practical usage in these networks.

Vektorová analýza v GIS systémech / Vector Analysis in GIS Systems

Životský, Tomáš January 2015 (has links)
This master's thesis deals with the geographic information systems   with an emphasis on so - called vector analysis . The aim of the thesis is to create a library that implements the internal representation   of geographic data and performs analytical operation over them .  The thesis describes the logical structure of the application and the hierarchy of abstract classes . In the form of pseudo -code is shown a set of individual computing operations . Work is strongly based on geographic system GRASS. This GIS is connectable through  import and export vector data in shapefile format. Concept of   storing layers is designed for ease of data manipulation and  their portability . The main idea behind the application is to split the library into individual modules . These modules are  independent , but also can benefit from each other's functions . In conclusion are demonstrated implemented vector analysis and  representation of their calculation .

USB host s mikrokontroléry PIC / USB Host with PIC Microcontrollers

Kučera, Pavel January 2010 (has links)
The aim of master thesis is implementation of USB host in a microcontroller PIC. The thesis contains description of ways of peripherals to computer connections with detailed description of USB bus. There are also discussed several approaches in implementations USB host for embedded systems. A concept of layered USB host system is designed on the basis of analysis of the state of the art. Finally, the designed system is implemented in microcontroller. Resulting firmware of development kit is tested on real USB device.

Vliv uspořádání krajiny na erozní a odtokové poměry povodí / Influence of the landscape management on erosion and runoff conditions of the catchment

Hájek, Daniel January 2016 (has links)
Aim of this study is to evaluate the effects of landscape structure on soil erosion and runoff conditions of given area with help of digital elevation model and relevant GIS data. Analyses of soil erosion by water and runoff were processed for current conditions and several other variations. Based on this analyses and results was performed an evaluation of all model variations.

Trasování významných bodů ve videosekvenci nestacionární kamery / Interest Points Tracking in Video Sequence of Non-stationary Camera

Studený, Pavel January 2016 (has links)
The thesis deals with the issue of tracking feature points earned from videosequences of hand helded camera. The work is focused on the case of moving camera and static background, and events that are associated with this case and can occur. There is studied the movement of the camera, which is given its direction and speed. The aim of this work is the election and the subsequent implementation of three fundamentally different methods suitable for tracking feature points in case of moving camera and their comparison according to set criteria. On the basis of comparison will be under pre-defined conditions chosen algorithm that is best able to deal with tracing these points.

Detekce akutní ischemie v EKG signálu pomocí specifických svodů / Detection of acute ischemia in ECG signals using vessel-specific leads

Lysák, Karel January 2016 (has links)
This master’s thesis deals with methods for detection of myocardial ischemia in the ECG signal. There is explained the principle of spreading of electrical activity through the heart muscle and its manifestations on the ECG. There are also mentioned the causes of myocardial ischemia and various methods of its detection in the ECG signal. In great detail there is explained the process of implementation of the two selected detection methods of myocardial ischemia in MATLAB. These methods are tested on the data from The PTB Diagnostic ECG Database. Finally, there is the presentation of detection results on used data and overall assessment of created algorithms.
