Hardware Acceleration of Cipher Attack
Okuliar, Adam ; Slaný, Karel (referee) ; Vašíček, Zdeněk (advisor)
Hardware acceleration is often good tool to achieve significantly better performance of processing great ammount of data or of realization of parallel algoritms. Aim of this work is to demonstrate resoluts of using FPGA circuits for implementation exponentially complex algorithm. As example haschosen brute-force attack on WEP cryptographic algorithm with 40-bit long key. Goal of this work is to compare properties and performance of software and hardware implementation of choosen algorithm.

Detection of heavy metals in liquids employing laser-induced breakdown spectroscopy
Skočovská, Katarína ; Hrdlička, Aleš (referee) ; Novotný, Jan (advisor)
The diploma thesis deals with the use of laser induced breakdown spectroscopy (LIBS) for detection of heavy metals traces, copper and lead, in aqueous solution of copper(II) sulphate pentahydrate and lead(II) ethanoate trihydrate. Results obtained by using single and double-pulse LIBS are compared. The theoretical section focuses on the issue of heavy metals and detection possibilities, describes the fundamental principle of LIBS technique and its modification for liquid analysis. The experimental section describes analyzed samples, the experimental apparatus, double-pulse technique, and method of spectral analysis. The moving breakdown model, which theoretically predicts optimal values of some experimental parameters, is explained briefly in section Optimalizácia. This model has been tested, however the results of experiments did not prove the theory. Furthermore, the experimental section reports the process and results of the optimization of all key measurement parameters and obtaining limits of detection from calibration curves.

Aerodynamic analysis and design modifications of L 410 NG aircraft wing-fuselage junction
Derevjanik, Šimon ; Pejchar, Jan (referee) ; Popela, Robert (advisor)
This thesis deals with CFD analysis of a wing-fuselage junction on L410NG airplane. Possible modifications are proposed as well. Calibration problem solved in the introduction serves as a pathway for validation of the results and gives insight into the CFD methodology. The main part analyses the airplane's flow field and shows the details of the modelling process. Description of the computing network followed by final evaluation is presented. Next part is devoted to the creation and aerodynamic analysis of the modified geometry. Final part of the work compares both basic and modified geometry.

Intelligent optimization module for company information system
Zigo, Ľubomír ; Ondroušek, Vít (referee) ; Krejsa, Jiří (advisor)
Diplomová práca sa zaoberá návrhom a realizáciou inteligentného optimalizačného modulu pre podnikový informačný systém. Optimalizačný modul bude vytvárať celoročné plány údržby s rovnomerným množstvom údržbárskych aktivít v jednotlivých týždňoch a plány pre výrobu s pravidelnými odstávkami. V úvode je uvedený prehľad použiteľných optimalizačných metód, z ktorých sú vybrané metódy pre ďalšiu fázu, testovanie. Nelineárna metóda najmenších štvorcov z Matlab Optimization Toolbox, genetický algoritmus a ABC algoritmus budú otestované na zadanej plánovacej úlohe. Na základe výsledkov testu bude najlepšia metóda implementovaná v podnikovom informačnom systéme. Takto doplnený informačný systém umožňuje vytvárať kvalitnejšie plány údržby a tým zvýšiť celkovú efektivitu podniku.
