Use of Mobile Device Sensors in a Car
Aron, Lukáš ; Široký, Vít (referee) ; Žák, Pavel (advisor)
This thesis analyses the use of an accelerometer commonly present in a mobile device for the measuring of vibration in a vehicle. Such measurements are used to map the quality of the road surface. The signal from the accelerometer and the current travelling speed of the vehicle are evaluated according to a threshold function. This function allows for a determination of whether the signal reported by the device signifies a pot-hole or another type of defect on the road surface. If the defect is determined to pose a threat to a vehicle travelling at higher speeds, then this fact is saved into the memory of the device. The second part of this thesis deals with the design of an internet and a mobile application, which is able to collect all measured data processes using cluster analysis and then shares the results with other participating devices. Tha practical results is that a map of road surface defect is thus created, which is then displayed to road users. This thesis deals with theory of mobile device sensors, including signal processing, as well as the design creation of the internet and mobile application.

Speed Measurement Using Radar
Martinů, Lukáš ; Široký, Vít (referee) ; Maršík, Lukáš (advisor)
Bachelor's thesis is focused on method of object's speed detection using a low-cost continuous wave radar module. In the first section, it describes differences between basic types of radar modules and their fundamental principles. The main part of thesis is dedicated to signal processing of radar modules K-MC1, K-MC4, that contents data to analyze moving objects. Doppler effect is used to determine the object's relative speed. Moreover, there is used FSK technique to measure the distance and there are solved issues associated with cosine factor. To verify the performance and stability, the application is tested on a several appropriate objects. In the end, the implemented application is evaluated and the possible continuation of this work is stated.

A Tool for Analysis of User's Typing Skills
Giertli, Anton ; Široký, Vít (referee) ; Herout, Adam (advisor)
This bachelor thesis is dedicated to analysis of user's typing. The reason of its origin is the aim to provide complex view on user's typographical skills. Its result is an application compatible with the 32-bit operating system Microsoft Windows, providing user with statistics when requested. These statistics include data about typing speed, error rate, typos, average word length, histogram of time differences between two keystrokes, etc. Thanks to this, user can work on his skills, watch their development in time and stay motivated for selfimproving. Thesis is also concerned with problems connected with implementations of application on Microsoft Windows platform.

Kinect-Based Desktop Controller
Czompál, Zsolt ; Široký, Vít (referee) ; Žák, Pavel (advisor)
The aim of this master's thesis was to create a user interface that allows controlling the PC using voice commands, static poses and dynamic gestures. It contains an implementation of a natural user interface that emulates the functionality of the keyboard and the mouse. In this thesis for detecting and tracking the user was used the sensor Kinect. For implementation I have chosen platform Windows and the Kinect for Windows SDK with programming language C#. During the implementation and testing of the interface, sensor Kinect for Xbox 360 was used. The result of this master's thesis is a natural user interface that allows controlling desktop applications without using keyboard or mouse, and that is comfortable and user-friendly.

WAN/LAN Manager for iOS
Jakubis, Tomáš ; Široký, Vít (referee) ; Maršík, Lukáš (advisor)
Cílem tohoto projektu je vytvořit aplikaci pro systémy iOS pro správu síťových zařízení, klienty a konfigurace zařízení. To zahrnuje projektovou analýzu, návrh aplikace, její implementaci a testování. Aplikace se skládá z klientské a serverové strany, databáze a~komunikačního protokolu. Výslední aplikace je pak porovnána se stávajícími řešeními s~podobnými výsledky. Výsledky testů ukázaly určité nedostatky a nevýhody řešení. Možná zlepšení a budoucí vývoj byly popsány. Na závěr, po dalším vývoji má aplikace potenciál stát se používanou v praxi.

QR Reader for Android
Loskot, Radim ; Široký, Vít (referee) ; Maršík, Lukáš (advisor)
This bachelor thesis focuses on the topic of reading the QR codes with the aim of designing and description of the implementation of QR codes' reader application for Android mobile platform. In theoretical part it analyzes structure of the QR codes including the way of information encoding and states the possible reference approaches of decoding them. With regard to the target platform Android it proposes algorithms for the detection of QR codes in the real time image and for decoding of the captured image from a mobile phone camera. At the end it evaluates the reliability and efficiency of the implemented functionalities and considers possibilities of their further development.

Information System Assessment and Proposal for ICT Modification
Martincová, Petra ; Široký, Vít (referee) ; Koch, Miloš (advisor)
This master´s thesis contains an explanation of basic terms and principals used in an issues of information systems. Part of this thesis are analyses of a current state of an information system in a selected company and evaluation of its effectiveness. A set of improvement propositions of the current state was created based on those analyses with both balance and effectiveness of an IS taken into account.
