In-System Programmer for ICSP Interface of Pic Microcontrollers
Doležal, Pavel ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
This thesis is dealing with a design of programming device with the expected use for Microchip PIC 16F and 18F microcontrollers. Individual chapters are dedicated to aspects of circuitry, printed circuit board design and user software tools. The proposed device is based on PIC18F67J50 microcontroller, graphic LCD diplay, and memory card interface. Design can be easily adjusted in order to support wide range of devices. Microchip's In-Circuit Serial Programming protocol is described with focus on previously mentioned family of devices. Working prototype of the programmer is attached to this thesis as a demonstration of a practical outcome.

The Testing Eqipment for Digital Circuit
Urbánek, Petr ; Bohrn, Marek (referee) ; Šteffan, Pavel (advisor)
This bachelor’s thesis deals with a device designed for testing digital circuits, especially logic gates and operational amplifiers. This equipment will be used by laboratory exercises, so it will check the operational status of components. The unit will used to display LCD, which will help interact with and will enable connect to PC via the USB bus.

JavaME communication client
Svoboda, Pavel ; Mácha, Tomáš (referee) ; Číka, Petr (advisor)
This diploma thesis deals with developing multimedia applications on Java Micro Edition platform. The aim of this work is to design and implement the application which could establish a call between two users. The first part of the work describes J2ME platform, its two configurations and profiles. Next part is focused on Session Initiation Protocol and Real-time Transport Protocol. The application design consists of choosing the suitable virtual machine JVM, SIP and RTP libraries. The main part of this work describes application structure, graphic user interface and installation packages creating. It also shows a way of customizing the media stack - Java Media Framework, version Cross Platform.

Probe for Determining the Surface Condition of Small Diameter Barrels
Procházka, Adam ; Goldmann, Tomáš (referee) ; Malaník, Petr (advisor)
This thesis focuses on the analysis of methods for measuring surface profiles, as well as the design and implementation of a device for their measurement. The implemented device utilizes non-contact triangulation profilometry techniques to determine the surface profile by projecting a laser line onto the surface and capturing the projected shape at a non-zero observation angle. It alse collects information about the surface’s image texture under LED illumination. In addition to data on image texture and profile, data on the position of the captured images is also collected using a sensor measuring the device’s distance from the end of the barrel. The work also includes the design and implementation of custom control modules for the chosen LED and laser diode. The output from the device is presented in a user application. The device is designed to function in tubes with diameters from 40 millimeters.

Analysis of Ministry of Health of the Czech Republic Communication During the COVID-19 Pandemic
Voldřich, Adam ; Bahenský, Vojtěch (advisor) ; Riegl, Martin (referee)
The Czech Republic was hit by Covid-19 in several waves similarly to what other countries around the world have been experiencing. Crisis and risk communication are essential in such perilous times. In the Czech context risk and emergency communication had several significant properties, there were several Health Ministers that changed during a very short time, communication proved to be ill-prepared and without unified vision and failed to systematically improve. This study uncovers those shortcomings using content analysis of official statements made by the Ministry of Health of the Czech Republic and effective comparison of each Health Minister against CDC methodology for risk and emergency communication. The technocratic populism enabled the communication to be framed in a quick response manner while bypassing institutionalized channels, which led to the creation of an illusion of somewhat successful risk communication. The most important underlying issue is the lack of unifying concept of risk communication and inconsistency which led to general confusion and increasing distrust in institutions that ultimately hampered the government's efforts in resolving the situation.

Childhood obesity - the epidemiological study
Mádlová, Markéta ; Kunešová, Marie (advisor) ; Kudlová, Eva (referee)
Obesity is considered to be one of the diseases related to the change in the lifestyle, leading to increased incidence of myocardial infarction, type 2 diabetes mellitus, hypertension and other diseases. Due to the progressively increasing prevalence of obesity in adulthood, prevention of obesity has to start in childhood and adolescent, in which also increase in prevalence of obesity was found. Actual prevalence of overweight and obesity was tested in this thesis by different standards (5. NAS, WHO, IOTF, CDC) in Czech children population in age of 6.5 - 7.5 years in 2013. Its trend since 1951 was evaluated. Since 2008 maintaining of the values in all categories at the constant level was found. The role of risk factors assessed by personal, family and school questionnaires in overweight prevalence was tested. The most important factors were diet, exercise and family factors. Increased weight/height ratio (WHtR) marker of adipose tissue was found in the category of normal weight children also and it shows the link with above-mentioned risk factors of diet, exercise and family prediction. Key words Obesity, Overweight, Prevalence, Childhood, BMI, 5. NAS, WHO, IOTF, CDC, COSI, WHtR, Waist circumference, Risk factors
