Měření kvality a dostupnosti GSM sítě / Quality and accessability measurement of GSM network

Vondra, Marek January 2011 (has links)
The thesis is specialized on a possibility of measuring qualities and availability of a cellular radio system and also on evaluation qualities, fruitfulness interface, permeability etc. It includes short description of a basic mobile technology. Further analysis of the possibility of measuring the mobile network and how implement the measure. It also includes a draft program for measuring and evaluation of the GSM network with help several tests by a mobile phone connected through the Bluetooth.

Zařízení pro měření tepové frekvence / The heartbeat counter

Malínský, Zdeněk January 2008 (has links)
Heart rate variability belongs to basic and most frequently interpretation of physiologic statement in medicine. The pulse rate serves as an indicator of the heart activity. The subject of this diploma thesis is projection of the heartbeat counter. The work describes electrocardiograph and separated waves, ways of calculation heart rate, characteristics mechanism for measuring and other necessary information about heart rate measuring. This master thesis fixates on heart rate-calculation from including R-R intervals. Here is described whole project of heartbeat counter, properties of separated blocks and calculation of useful parameters. Further there is noted software resolution for the microcontroller and program for the calculation of heart rate frequency including unwinding signal preprocessing and detection of separated QRS complexes. The products of this diploma thesis are the circuit including the board circuit and codes of separated programs.

Identifikace regulované soustavy, jednotka pro spalování biomasy / Process identification, experimental unit for biomass combustion

Macalík, Radek January 2008 (has links)
This thesis dissertates the identification of existing experimental unit of biomass combustion. It analyses particular methods of identification, the selection of a model and methods of the estimation of parameters, especially by using last square method and analysis of time-response characteristic. It describes common identification procedure and particular algorithms which were used in practice for obtaining model’s parameters. The thesis also mentions popular software tools used for the modeling and the identification of systems. It comprises the implementation of obtained mathematic models using programming environment Borland Delphi as well.

RFID inventarizační systém / RFID Inventory System

Šindelka, Jiří January 2007 (has links)
This project deals with a survey of inventory system and accounting property. The purpose of the project is to study the SAP system, IS Apollo,  the database platform Oracle 10g, the RFID technology and to make a marketing research of a device for the chip EPCglobal UHF Gen2. On base marketing research propose and implement RFID inventory. At implementation target will be collective reading RFID tags. Further I will implement application simulating evidence systems and I will design data transmission to those application that will be also used at transmission data to the IS Apolla. I decided to implement the inventorying in the development environment Microsoft Visual Studio 2005 Standard Edition C#. Application simulated accounting property and data transmission I decide to implement in the development environment Borland Delphi 7.

Ferramenta de visão computacional para processos fotogramétricos / Tool of computer vision for joined fotogrametrics

Sandro Roberto Fernandes 29 April 2008 (has links)
Nesta dissertação é apresentado o desenvolvimento de uma ferramenta computacional para o processamento de pares de imagens estereoscópicas obtidos por câmeras aéreas métricas e não métricas. O programa foi desenvolvido na linguagem C++ e foi utilizado a biblioteca OpenGL. O resultado obtido é uma imagem tridimensional de onde pode ser extraídas cotas de altura e formas de terreno. Estas imagens poderão ser usadas no estudo de áreas de risco em encostas. / In this dissertation is presented the development of a computational tool for the processing of pairs of images estereoscópicas obtained by metric and not metric aerial cameras. The program was developed in the program language C++ and the library was used OpenGL. The result of the program is a three-dimensional image from where it can be extracted height quotas and land forms. These images can be used in the study of risk areas on slopes.

Metody FFD / FFD methods

Novák, Jiří January 2017 (has links)
The diploma thesis deals with the topic of free-form deformations. The main goal of this work were elaboration of theoretical knowledge about this issue and the programming of selected methods od free-form deformations. The first part describes the required spline theory, matrix calculus and free-form deformations. The resulting version shows three programs. The first program compares the selected free-form deformation methods to the example of the 4x4 control point grid. The second program serves as a generalization for the general case of grid of control points. The last program is based on direct manipulation of arbitrary surface point and following recomputation of the control points to obtain demanded shape.
