Computational tool for a stress-strain analysis of the mechanically loaded circular and annular plate
Dohnal, Jakub ; Majer, Zdeněk (referee) ; Ševeček, Oldřich (advisor)
The bachelor's thesis primarily deals with the creation of a computational tool for stress-strain analysis of rotationally symmetric circular and intercircular plates. The commercial software MATLAB and its component APP DESIGNER were used for this purpose. The program uses analytical relationships of general solid mechanics to solve differential equations for several types of plates and loads. Part of the bachelor thesis is also a parametric study comparing the outputs of analytical and numerical model based on the finite element method, aimed at identifying the practical application of the analytical solution and its accuracy for a particular case of the plate.

IoT Application Deployment Platform
Hrvol, Marek ; Smrčka, Aleš (referee) ; Kočí, Radek (advisor)
The aim of this work is simplifying deployment of Internet of Things in households or smaller companies and also reducing the need of maintenance of created network. Main goal of this web application is creating platform capable of deploying applications across ARM single-board computers. Moreover, application provides intuitive preview of all registered devices including its state, shows all the necessary data and informs user about failures on devices.

Telemetry Data Collection and Evaluation
Spurný, Jan ; Krajsa, Ondřej (referee) ; Číka, Petr (advisor)
This thesis describes design and creation of application which collects and values telemetry data. Thesis consist of design and implementation which describes whole system, server settings as well as approach how to consume any given data. Corner stone of this application is based on given data from telemetry station (sensors) and projecting them on the map background. Application consist of user interface and logic how to project any given data into the map. Graphics interface is created using HTML, JavaScript and CSS programming languages. Logic itself is programmed by using backend language PHP including Laravel Framework in combination with MySQL database. Result of this thesis is working implementation covering administration user interface, working cooperation of MQTT server and APIs. There are also implemented all necessary parts for enablement of user interface with cooperation with map background layer. Implementation creates two possible ways how to install package necessary to run this app on Ubuntu system.

Analysis of email spam sources
Caha, Tomáš ; Kubánková, Anna (referee) ; Komosný, Dan (advisor)
The first part of this thesis deals with an approach of designing and developing of application for IP geolocation using various geolocation databases. Methods of geographical location of network devices and amount of available data provided by chosen commercial and freely accessible geolocation databases are presented. The data are summarized with focus on methods of obtaining information about IP addresses from various databases. In the paper there are also presented ways used to develop the Python application and its parts, which can be easily reused in other programs. The command line program was created to demonstrate that all parts of the developed application work properly. The whole application is freely accesible under the conditions of the MIT license, published on GitHub (https://github.com/tomas-net/ip2geotools/) and in the Python package index PyPi. The second part of this thesis deals with the description of cyberthreats and the use of developed application to mass geolocation of IP addresses that are listed in chosen freely accessible lists as sources of email spam or cyberattacks. Geographical analysis of cyberattacks sources shows countries of origin. Results of analysis are presented in graphs and maps.

Natural Language Processing: Analysis of Information Technology Students’ Spoken Language
Stanković, Aleksandar ; Šťastná, Dagmar (referee) ; Ellederová, Eva (advisor)
Tato bakalářská práce se zabývá problematikou nových technologií umělé inteligence při zpracování přirozeného jazyka. Práce je rozdělena na teoretickou a analytickou část. Teoretická část přistupuje k problému rozdělením do tří kapitol: umělá inteligence a statistika, zpracování přirozeného jazyka a IBM Watson Natural Language Understanding. Každá z těchto kapitol je rozpracována včetně uvedení alespoň jednoho příkladu z praxe. V první kapitole je hlavním cílem vymezit teoretický rámec umělé inteligence a jejích postupů, zatímco ve druhé kapitole je vysvětlena problematika zpracování přirozeného jazyka a jeho primární funkce včetně jeho vztahu k samotné umělé inteligenci. Cílem třetí kapitoly je představit porozumění přirozenému jazyku jako primární nástroj pro analýzu, která je realizována v analytické části práce. Analytická část se zabývá analýzou mluveného jazyka studentů prostřednictvím různých metod. Transkripce shromážděných vzorků videí je provedena strojovým překladem jako aplikací zpracování přirozeného jazyka, zatímco textový výstup je analyzován prostřednictvím nástroje porozumění přirozenému jazyku. V analytické části, která popisuje výzkumnou metodologii, prezentuje a interpretuje výsledky výzkumu, jsou využívány aplikované znalosti z teoretické části práce.

Web Tool for Creation, Management, and Use of a Database of Sports Poses
Křivánek, Tomáš ; Tesařová, Alena (referee) ; Herout, Adam (advisor)
This paper is focused on two searching methods and how they can be used in any searching and in any web application. Two most important qualities of any search are speed and accuracy. One of the best methods in terms of speed is so-called live search. This method provides results immediately when the user starts typing their search expression. That is why in many cases, the user does not even have to finish their expression, because when seeing the result, the user can immediately access it. Search accuracy is often achieved by using keywords or some part of text. Another common way to organize and fetch documents are tags: a short string which identifies a post or a photo. Multiple tags are then used similarly to plain keywords. This work proposes to use tags as a new searching logical language, where presence and/or absence of tags can be required. For this purpose I created a simple logical language "Queries", because they can be used very similarly to database queries. In my case, the language and the user interface is made very simple so that a normal user can specify the query himself. This search tool is showcased in a web application focused around yoga poses. Both methods are used there -- the user can search in the yoga poses database by name or by the queries language.
