Partial purification and characterization of polygalacturonases of Geotrichum candidum.
Jäger, Jakub ; Breierová, Emília (referee) ; Stratilová, Eva (advisor)
This work discusses the possibilities of using microbial degradation of grape pomace, main waste material from wine production, to preparate industrially important enzymes. The issue is focused on the production of pectolytic enzymes, particularly polygalacturonase, by Geotrichum candidum CCY 16-1-29 via solid state fermentation on grape pomace. The theoretical part of the bachelor thesis focuses on studying plant cells and saccharides from which the plant cell wall is made of, mainly pectin. Cell wall sacharides were used as a carbon source for solid state fermentation (SSF) and pectin as an inductor of pectolytic enzymes. This bachelor thesis also deals with the enzymatic degradation of cell wall polysacharides. The greatest attention is paid to degrade pectin and pectolytic enzyme function. Production of pectolytic enzymes is mentioned subsequently. The last chapter from the theoretical part is dedicated to technical use of pectolytic enzymes. In the experimental part of this work I deal with the partial purification and characterization of majority polygalacturonase produced on the seventh day of cultivation, when another increase of extracellular polygalacturonase activity occurred. The yield of cultivation was 43,5 mg of protein extract /100 g of grape pomace. The extract contained protein, and its activity was lyophilisate. Its specific activity was protein. The enzyme was produced in at least four forms differing in pH optimum (4,0; 4,4; 4,8; 5,2). The pH optimum for majority polygalacturonase was 4,8. Action pattern of this enzyme determined as the dependence of polymeric substrate viscosity decrease on its degradation showed that the enzyme is a typical polygalacturonase with random action pattern (EC 3.2.1.15).Value of Km reached indicating a high affinity for this substrate. The amino acid sequence "SNNVVSNVNILSSQVVNSDNGVR" obtained by mass spectrometry after SDS-PAGE and tryptic digestion, was identified as a stretch of primary structure of polygalacturonase of Ap2PG1 G. candidum based on the comparison with proteins from the Uniprot database. It shows the highest similarity with other polygalacturonases of G. candidum S31PG1, S31PG2 and G. klebahnii PSE3. On the basis of this similarity to enzymes produced by phytopathogenic strains of G. candidum and the fact that this enzyme was not produced only in the early stages of cultivation, it can be assumed, that the strain of G. candidum CCY 16-1-29 acted also as a phytopathogenic strain.

Web information system for web reality brokers
Vávra, Štěpán ; Karásek, Michal (referee) ; Bílý, Tomáš (advisor)
Title: Estate agency internet information system Author: Štěpán Vávra Department: Department of Applied Mathematics Supervisor: Mgr. Tomáš Bílý Supervisor's email address: tomby@kam.mff.cuni.cz Abstract: The aim of this work is to explore the possibilities offered by the PHP language in combination with the Apache web server and MySQL database in order to implement a web application. This web should be able to compete with other similar applications on the internet, especially in the field of real estate, both by its functionality and graphic design. A significant part of the task should consist of the design of the application. Consequently, our objective was not to find and use the most suitable framework or other tools of support, such as content management system. The programming phase of the project was then done using the methods of Object oriented programming. Keywords: web application, PHP, XHTML, JavaScript

Sensitivity analysis of the energy rating of buildings
Auer, Zbyněk ; Plášek, Josef (referee) ; Šikula, Ondřej (advisor)
The master´s thesis was focused on parametric computer simulations of the energy performance of buildings. The aim is to determine the sensitivity of the individual operating and climatic influences on the final energy demand of the building, which will be reflected in final form Et-curve. Parametric simulation for building energy efficiency is planned to use the BSim and ready climatic database for a specific location in place of the assessed building. The outcome of the evaluation of the real use of property in Et-curve using a custom application.

Head Pose Estimation from Photography
Szentandrási, Tamás ; Juránek, Roman (referee) ; Behúň, Kamil (advisor)
The aim of this work is to propose and implement a head pose estimation system using Random Forests, with photographic input. This work uses a version on Random Forests with using Fisher Linear Discriminant Analysis for node splits. It also uses a number of tools to achieve this goal, the OpenCV library, SQLiteCpp library, and the aflw database. This work created an accurate head pose estimation system reusable for future Computer Vision tasks.

Synchronization of DNS Records between LDAP Database and DNS Server
Bašti, Martin ; Matoušek, Petr (referee) ; Čejka, Rudolf (advisor)
Cílem této práce je prozkoumat možnosti uložení DNS dat v LDAP databázi a jejich oboustranné synchronizace s DNS serverem s využitím standardních technologií, paralelizace a jednoduché rozšiřitelnosti o podporu různých DNS a LDAP serverů s různými DNS schématy. Práce dále popisuje různa schémata pro uložení dat v LDAP databázi a analyzuje problémy spojené se synchronizací a navrhuje jejich řešení. Výsledkem je prototyp synchronizační aplikace s doporučenými nastaveními pro DNS server a LDAP databázi, která je schopna efektivně synchronizovat DNS data.

Analysis of real data for Customer Services Department
Maximilián, Michal ; Šimůnek, Milan (advisor) ; Veselý, Jiří (referee)
The goal of this bachelor thesis is to find certain relationships by analyzing real CRM data. These relationships would then be used to specify a draft of content of companys new webside. The analysis will be completed through CF-Miner and KL-Miner procedures, which are procedures of LISp-Miner system, which is an academic system for Knowledge Discovery in Databases, based on the GUHA method. The whole analysis process is divided according to the phases of the CRISP-DM methodology. The contribution of this thesis is primarily to find unknown relationships and dependencies, which will be effectively used in real life, along with the introduction of methods and techniques used in the analysis, and last, but not least, the introduction of LISp-Miner system itself. The thesis is divided into a theoretical and empirical sections. In the first three chapters, I will explain what is meant by Knowledge Discovery in Databases and what techniques, methodologies and procedures are used during this process. Further, I will explain individual phases of KDD corresponding to the CRISP-DM methodology. Towards the end of the theoretical part, I will describe LISp-Miner system that has been used for this analysis. The empirical section is divided according to the CRISP-DM methodology, where I will first introduce the scope and the data that will be analyzed. In further steps, I will prepare the analyzed data and use them to solve analytical problems. At the end of the empirical part, I will interpret the results of individual analyses and suggest use in real life.

The Master’s thesis ”The Implementation of the Advanced Filtering Based on the Packets’ Classification using Linux” is intended to the realization of an internet gateway. The gateway serves to make the connection between local network and the internet. The thesis contains a short theoretic description of parameters and types of QoS services. The classful and classless queues are mentioned in detail. The last theoretic part refers to the introducing of LDAP protocol and its usage. The practical part of this thesis captures the configuration of firewall, dns and radius server connected with LDAP databases. The thesis also contains detailed description of the production QoS by HTB with L7-filter including the compilation of system’s core. The end of the thesis contains the series of tests of created scripts.
