Generator of Cyber Attacks
Halaška, Peter ; Burda, Karel (referee) ; Hajný, Jan (advisor)
This work deals with the security of computer networks based on TCP/IP protocol stack. The main objective is to develop a generator of DoS flooding attacks which carries out attacks such SYN flood, RST flood, UDP flood, ICMP flood, ARP flood, DNS flood and DHCP starvation. The theoretical part describes the features of the mentioned attacks and protocols or mechanisms associated with them. Next part deals with the comparison of selected tools (Hping3, Mausezahn, Trafgen) in terms of number of packets per second (pps) and the link utilization (MB/s). The practical part describes design and implementation of the new attacking tool. There is explained the importance of it’s individual modules, it’s installation and usage options. New tool is also being tested. Then there is described the development, options and installation of control interface which is in the form of web application.

System for processing of GPS data from multiple mobile devices
Jurča, Josef ; Červenka, Vladimír (referee) ; Lattenberg, Ivo (advisor)
The aim of this thesis was to create an information system which consists of a mobile application, server and web application. Mobile application is designed for operating system Android and it is used for sending GPS coordinates of mobile devices to the server. These data are later processed by server and stored in database. Web application displays the current location of mobile devices in user group on a map, it also displays location history and statistics. Accuracy of the station location can be enhanced by using DGPS assuming that one of stations in a group does not change its location. The system was designed and then developed using modern web technologies and frameworks including PhoneGap, Ionic, Node.js, Express, MongoDB, Mongoose and AngularJS. Further measurements, that were performed, are supposed to present the effect of DGPS to location accuracy determination.

Word Games for Acquiring Linguistic Data
Koriťák, Jan ; Otrusina, Lubomír (referee) ; Smrž, Pavel (advisor)
This thesis focuses on design and implementation of a basic word game for guessing given word with knowledge of its paraphrase. The output of the game is annotated word data, which can be further used as a base in creation of parallel of paraphrase dictionary. The game consist of two mutually communicating parts - the client part, which mostly takes care of displaying the game interface and the server part, which takes care of the actual computation. There were used modern web technologies during implementation, especially client-side JavaScript a server-side Node.js.

Precipitation Forecast from Weather Radar
Tábi, Matej ; Milička, Martin (referee) ; Burget, Radek (advisor)
The aim of this bachelor thesis is a web application, which solves a short-time precipitation forecast for Czech Republic. The forecast is created for the next one hour and consists of four radar frames with a 15 minutes distance between them. The task is solved in three main steps. In the first step, the actual information from CHMI webpages is obtained. In the second step, the recieved data is processed - precipitation fields are identified and in the last step, movement vectors of these precipitation fields are calculated. The result of the thesis is a fully working web application. The forecast success rate is at the level from 30 to 60%.

Software for Online Record of Sales
Nguyen, Viet Bach ; Vojíř, Stanislav (advisor) ; Smutný, Zdeněk (referee)
One of the key elements of retail facilities is a cash register system because it optimizes the checkout process. Even though retail firms usually present a conservative behavior towards innovations, they still need both human resources and high-quality machines to help maintain the smoothness of daily processes, especially with cash registers and POS systems since they carry out the most crucial process in the whole establishment. Law and regulations are also an issue that firms must deal with. Most of cash registers and POS systems in the Czech Republic are to be deemed useless due to the introduction of the new Act of Online Record of Sales. This means that old machines and systems will have to be replaced by newer ones. The goal of this thesis is to design and implement a solution for retail firms to cope with legal requirements of the regulation. To achieve this goal, the thesis first deals with the requirement analysis of POS systems. It also provides a detailed analysis among significant features of the statutory regulation while describing the fundamentals of that regulation. A design of a POS system is then proposed based on gathered information. Its implementation is then carried out using the web as its platform. The POS system implements a client-server model using some of the newest and most popular JavaScript web technologies including jQuery, Express framework, Node.js and MongoDB database system. The output of this work is an on-line application which provides many important features to support retail businesses and thus can become a convenient and beneficial solution for entrepreneurs.

Application of MongoDB with Node.js
Hejtmánková, Kateřina ; Palovská, Helena (advisor) ; Mittner, Jan (referee)
The aim of my thesis is to provide a collection of examples about document oriented MongoDB database using Node.js platform, specifically using the Mongoose program, for object-document mapping (ODM). The aim is met by analysis of Mongoose and Async module, which provides functions for more comprehensive asynchronous querying, needed for working with input/output to the MongoDB database in Node.js. The main merit of this thesis is (in the general sense) a demonstration of how to create a administration part of web application (backend) in Node.js, applying document oriented MongoDB database. The thesis discusses, in the theoretical part, about characteristics and significance of document oriented MongoDB database, about characteristics and architecture of Node.js platform employing untyped and multiplatform JavaScript language and about object document mapping (ODM) programs for Node.js on MongoDB. The practical part contains a collection of examples, where in the first chapter introduces an instalation and execution manual of necessary programs. The next chapter is dedicated to simple examples of Mongoose module and in the last chapter there are stated the complex examples of Mongoose and Async modules, which are the main merits of this thesis.
