The genus Caliciopsis contains several representatives of the ascomycetous fungi which produce cankers on conifers. They comprise an interesting group with respect to morphology, physiology, and host response but have received relatively little attention in the past. The biology of this fungus is not totally elucidated. This study is focused on the description of seasonal spore dispersal of Caliciopsis pinea Peck and its relation to meteorological conditions which is needed for more precise and effective control of the disease. For this experiment the plantation of Pinus radiata in Carcheri (Lastra a Signa, Florence, Italy) was chosen. This plantation had symptoms of infection. A rotating arm spore trap and a weather station were installed here to obtain data from May to November 2016. Air samples were evaluated by qPCR with a very low detection limit. It has been found that spore traps are suitable for capturing the spore of this pathogen even with a very low incidence of inoculum in the air. Results show the presence of C. pinea inoculum throughout the entire sampling period with the highest peak in October. There is also a significant influence of precipitation on spore production. This work can help to better understand the life cycle of this pathogen. It can also contribute to enhance the control of this fungus and the protection of hosts.

This thesis focuses on the topic of honeypots technology and their use for network attacks monitoring. It theoretically analyzes the honeypots and their variants honeynet and honeytoken. The practical part describes how to deploy two open source solutions of honeypot, Kippo and Dionaea. Kippo honeypot can be classified, despite its limitations, as a high interactive honeypot. This solution emulates the SSH service and it is primarily intended for the detection and capture of brute force attacks on the service. Dionaea is a honeypot designed primarily for capturing malware. It aims to capture malware in the trap using the vulnerabilities of offered and exposed network services with the aim to obtain a copy of the malware for subsequent analysis. Data obtained from the real deployment of the proposed solutions are presented and measures in relation to the SIEM instruments are proposed as well as improved security of the protected network.

The content of this diploma is to create applications called maplets. The maplets are used to show influences of the coefficients in equation to their representation. The maplets are programmed in the program Maple. These tools should make teaching analytical geometry easy at high schools and in introductory university courses.

The aim of master's thesis is separation rubidium from cement bypass dust by columns based od hexacyanoferric and resins

This diploma work discusses the chemical and physical characteristics of phytic acid, its positive and negative influence on people’s health, on the substances usability in the human organism and also its possible use in the food industry. Methods for analyzing phytic acid in the feed and food industry are also discussed. This diploma work also states the characteristics of analyzed raw materials and, for the analyzed raw material malt, it also covers the technological procedure for its production. For direct determination of phytic acid in barley caryopses and in malt, the isotachophoresis (ITP) method was used. This diploma work contains results of phytic acid determination in treated and untreated barley and malt variants by 6 different varieties in 4 test stations - specifically for harvests during the years 2006 and 2007. The final work contains comparisons of phytic acid content in different varieties of treated/untreated barley and malt variants. Comparisons are always within a single test station. Comparison are also included of phytic acid content for single varieties (across all examined test stations). This work furthermore, presents decreases in phytic acid content after malting. The ITP method was evaluated as quick and relatively simple. A method by using tests (from a commercial company) for obtaining phytic acid content was also used. This diploma work lists results of phytic acid content determination in untreated barley and malt variants at two test stations, for the year of harvest 2007. Further, this work contains a comparison of phytic acid content in different varieties for the given test station. The method by using tests was evaluated as a orientation method. This work states comparisons of phytic acid content obtained by measurements during the years 2006 and 2007. The diploma work also compares ITP with the method realized by using tests in two test stations for 5 untreated varieties of barley and malt for 2007 harvest.

This thesis deals with robot path planning by means of ant colony optimization algorithms. The theoretical part of this thesis introduces basics of path planning problematics. The theoretical part either deals with ant algorithms as optimization and path planning tools. The practical part deals with design and implementation of path planning by means of ant algorithms in Java language.

This thesis, in its theoretical part deals with the process of cutting, abrasion-resistant layers properties and their contribution to increasing of cutting properties. The second part of the thesis is experimental. It aims to determine, compare and subsequently evaluate cutting properties of threading tools using matrix taps with different types of PVD coatings. During implementation of the experiment, constant cutting conditions have been ensured and the only variable was the different types of coating layers. Outcome of the experiment is measurement of cutting torques in relation on time and rate of wear of cutting tools.

Rešerše se zabývá teorií technologického způsobu zpracování materiálů, tzv. povrchového tavení. V první části rešerše je popsána samotná technologie a základní parametry ovlivňující proces tavení. Ve druhé části je uvedeno srování dvou základních typů laserů, a to Nd:YAG a CO2 laser. CO2 laser byl použit v případě našeho experimentu. Třetí část se zabývá vlastnostmi TiAl intermetalických slitin, především jejich fázemi -TiAl a -Ti3Al. Na závěr teoretické části je zmíněna oxidace TiAl intermetalických slitin. Experimentální část je věnována přetavování povrchu slitiny Ti-46Al-0,7Cr-0,1Si-7Nb-0,2Ni, a to v ochranné atmosféře dusíku. Tato část obsahuje výsledky několika experimentů, na jejichž základě bylo nutné stanovit potřebné parametry pro požadovaný proces tavení. Posledním krokem experimentu byla snaha o zvýšení hmotnosti vzorků v důsledku následné oxidace.

This diploma thesis deals with the use of canistherapy in the special education practise. It records the development, methods, forms and type sof canistherapy, included risks and benefits of this psychoterapeutic method. The research parts maps the relationship between the education of dog handlers and the quality of their fieldwork.

In this thesis we apply neural networks as nonparametric and nonlinear methods to the Central European stock markets returns (Czech, Polish, Hungarian and German) modelling. In the first two chapters we define prediction task and link the classical econometric analysis to neural networks. We also present optimization methods which will be used in the tests, conjugate gradient, Levenberg-Marquardt, and evolutionary search method. Further on, we present statistical methods for comparing the predictive accuracy of the non-nested models, as well as economic significance measures. In the empirical tests we first show the power of neural networks on Mackey-Glass chaotic time series followed by real-world data of the daily and weekly returns of mentioned stock exchanges for the 2000:2006 period. We find neural networks to have significantly lower prediction error than classical models for daily DAX series, weekly PX50 and BUX series. The lags of time-series were used, and also cross-country predictability has been tested, but the results were not significantly different. We also achieved economic significance of predictions with both daily and weekly PX-50, BUX and DAX with 60% accuracy of prediction. Finally we use neural network to learn Black-Scholes model and compared the pricing errors of...
