Analyzer of Web Application Optimization and Security
Štrbák, Boris ; Polčák, Libor (referee) ; Bednář, Martin (advisor)
The goal of this project was to create a web application that would automate the regular analysis of individual pages of the site and present obtained information to the user. Final product is a Single-Page application (SPA) created using JavaScript framework Vue.js with the Vuetify library. The server part, which contains REST API and scanning and analysis processes, is implemented in the PHP framework Laravel. Both parts are designed to run in a containerized environment. Docker is used for this purpose. The first part of the thesis describes the issues of site optimization, security and SEO. The mentioned findings were then used in the implementation itself.

Design of an Experimental Robotic Cell for Manupulation Operations
Bednář, Martin ; Kubela, Tomáš (referee) ; Pochylý, Aleš (advisor)
Final thesis is focused on design of experimental workplace with industrial robots for manipulation operations, that will be used for educational and demonstrational purposes. Integration of sub-systems and workplace layout are worked out in this thesis. Key factor is so called virtual commissioning. Unique solution, which is contained within final thesis, combines several software tools for the design of robotic workplace. Static 3D model created in Autodesk Inventor Professional is imported into Tecnomatix Process Simulate, where dynamic 3D model is made – simulation model respectively. The control element is softPLC by Beckhoff company created in TwinCAT software. The connection of simulation model and control element is realized using standardized communication protocol OPC UA. This combination proved to be a cheap tool for virtual commissioning in practice, because only one personal computer is needed for the job.

The Design of a Rules for the Hydropower Control of a Dam Reservoir
Bednář, Martin ; Kříž, Tomáš (referee) ; Menšík, Pavel (advisor)
The aim of the diploma thesis is to create an algorithm by which it will be possible to devise management rules. These management rules will be able to advise a more efficient use of the hydroenergetic potential of reservoirs with run-of-river small hydro. The actual algorithm will be created with a view to maximizing the profit from the operation of the hydropower plant and using the time course of electricity prices on the market. The rules designed by algorithm will be tested in a simplified way in selected period using simulation model.

FormLock for JavaScript Restrictor
Szabó, Matyáš ; Bednář, Martin (referee) ; Polčák, Libor (advisor)
This thesis focuses on protecting personally identifiable information (PII) during filling and submitting of web forms. Formlock, a prototype trying to resolve the PII leakage caused by forms by warning the user about the potentially malicious web forms and giving them an option to try and prevent the leak, is tested and then it's defensive capabilities are improved and integrated into Javascript Restrictor. Lastly, the new and integrated measures are tested and their possible future improvements are evaluated.

Extension Module with IR Communication Interface
Bednář, Martin ; Slaný, Karel (referee) ; Šimek, Václav (advisor)
This work is concerned with design of wireless extending module for the FITkit platform. The module is based on infrared communication. In this work the module itself is created, the components for the FPGA circuit are done and the software for the MCU is implemented. Additionally it is made possible to transmit or recieve codes of remote controllers for consumer electronics in variants of the NEC format.

Wireles Flying Object Telemetry
Bednář, Martin ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
This paper is engaged in specification, design and implementation of a telemetry module for flying object. Specifically, it focuses on the selection of the appropriate carrier frequency of the integrated circuit providing bidirectional communication to a sufficient distance and design of the protocol used in the transmission. Furthermore, the document focuses on the design of communication modules using these integrated circuits, altimeter sensor module, module to control the actuators and design of the application for mobile phones used to display the measured data. With regard to legislative and technical options, I chose a carrier frequency of 2.4 GHz. For this frequency is commercially available integrated circuit CC2511, which in cooperation with integrated circuit CC2591 should be able to provide telemetry range about 2 km. I chose BMP085 sensor for altitude measuring. It is communicating over I2C bus as well as a module for controlling the actuator, which uses a microcontroller ATMEGA48-20AU. The mobile phone communicates with the ground station via the USB bus.

Cutting as a finishing operation
Bednář, Martin ; Řiháček, Jan (referee) ; Císařová, Michaela (advisor)
The project elaborated design of technology production of the cutting by shaving operation. The component is made from sheet iron 11 321. Pursuant to of the literary pursuit a problem of the shaving and calculation was designed two operations of shaving. Recommended production choice was tool with nominal cutting force 173 kN in first operation and 68 kN in second operation.

Conference Information System
Bednář, Martin ; Rychlý, Marek (referee) ; Křivka, Zbyněk (advisor)
The .NET platform offers several frameworks, technologies and approaches for web applications development. A good survey of these technologies is necessary for selecting effective implementation technologies. The aim of the thesis was to create a conference information system as a web application on the .NET platform for the non-profit organization Zámecké návrší, p.o. including its deployment and operation in the production environment. Prior to the development, it was necessary to familiarize myself with the .NET platform and compare the frameworks for web development. The bachelor thesis presents the suitability of individual frameworks for different types of applications. Based on the .NET analysis, DotVVM framework was chosen to implement the conference information system. The development of application logic proceeded with the test-driven development method. Combining appropriate frameworks, technologies, and approaches has lead to effective development with the successful creation of a secure and fast web application.

Web Browser Extension Providing Protection of Company Data
Dvořák, Jan ; Bednář, Martin (referee) ; Polčák, Libor (advisor)
This thesis focuses on securing company data stored in SaaS storage. In contrast to data stored on-premise, data stored in the cloud face several additional risks, be it from the outside as well as from the inside of the organization. The main risk, whose impacts we try to mitigate in this work, is an accidental data leak by one of the organization's employees. An extension for the Google Chrome web browser was designed and implemented as a solution to this issue. Implementation complications rising from transitioning to a new version of the manifest are also examined in part of this work. The thesis is concluded with the execution of experiments simulating practical data loss scenarios and a verdict on whether a web extension is an appropriate means for creating a tool providing data loss prevention capabilities.
