Application of Genetic Algorithms and Data Mining in Noise-based Testing of Concurrent Software
Šimková, Hana ; Kofroň, Jan (referee) ; Lourenco, Joao (referee) ; Vojnar, Tomáš (advisor)
Tato práce navrhuje zlepšení výkonu testování programů použitím technik dolování z dat a genetických algoritmů při testování paralelních programů. Paralelní programování se v posledních letech stává velmi populárním i přesto, že toto programování je mnohem náročnějsí než jednodušší sekvenční a proto jeho zvýšené používání vede k podstatně vyššímu počtu chyb. Tyto chyby se vyskytují v důsledku chyb v synchronizaci jednotlivých procesů programu. Nalezení takových chyb tradičním způsobem je složité a navíc opakované spouštění těchto testů ve stejném prostředí typicky vede pouze k prohledávání stejných prokládání. V práci se využívá metody vstřikování šumu, která vystresuje program tak, že se mohou objevit některá nová chování. Pro účinnost této metody je nutné zvolit vhodné heuristiky a též i hodnoty jejich parametrů, což není snadné. V práci se využívá metod dolování z dat, genetických algoritmů a jejich kombinace pro nalezení těchto heuristik a hodnot parametrů. V práci je vedle výsledků výzkumu uveden stručný přehled dalších Technik testování paralelních programů.

Impact of Portugal on the European Union Training Mission in Mozambique
Snopko, Leonard ; Doboš, Bohumil (advisor) ; Kofroň, Jan (referee)
The thesis deals with the European Union Military Training Mission (EUTM) in Mozambique, which has been operational since 2021. The EU built on the foundations of the Portuguese training mission, which started training a few months earlier. Portugal, in particular, is a long- standing partner of its former colony on the African continent, with which it has regularly updated its bilateral Defence Cooperation Framework Programme - 'Programa-Quadro' - since the Carnation Revolution. In response to the insurgency by the militant group Ansar al- Sunna wa Jama'a (ASWJ) in Mozambique's northern region, Cabo Delgado, in October 2017, Portugal explored adding a new sixth cooperation Project with Mozambique to their Framework Programme. It was to support the training and capacity-building of the Mozambique Defence Armed Forces (FADM) for counter-insurgency operations. The formalisation of this project took place in Lisbon in May 2021 with the signing of a new 'Programa-Quadro' by both the Portuguese and Mozambican Ministers of National Defence. Simultaneously, Portuguese officials took the opportunity of the Presidency of the Council of the EU in the first half of 2021 to discuss the implementation of the EUTM Mozambique. It was to build on the Portuguese training mission to strengthen the FADM capabilities...

Jerry - keyboard and mouse sharing application
Klapová, Veronika ; Ježek, Pavel (advisor) ; Kofroň, Jan (referee)
The goal of the thesis is to develop a program that enables the control of multiple computers from a single workstation using a unified set of input devices. The program comprises a control application for Windows OS and a client application compatible with Windows, Linux, and macOS systems. The communication between computers is encrypted. A significant advantage of this software, as opposed to others, lies in its accurate key interpretation, independent of the controlling computer's current state, lay- out, or mapping. It ensures error-free typing of accented characters, operates without compromising system responsiveness, and imposes no limitations on virtual desktop con- figuration. The project encompassed not only program development but also bug analysis within both interface functions and documentation, and message propagation method- ologies within the Windows environment. 1

Nowcasting as the new potential predicting method for the policy-makers
Chaloupka, David ; Kofroň, Jan (advisor) ; Parízek, Michal (referee)
This bachelor's thesis examines the role of nowcasting as a real-time data pre- diction approach in policy-making. The study compares the informative value of macroeconomic forecasting during crises and the potential of nowcasting as an alternative. By analyzing selected forecasting and nowcasting indexes from 2019 to 2022, the research fnds that nowcasting performs well during during 2020, which was afected by COVID-19 pandemic. However, it faces limitations in terms of prediction horizon and data requirements. Although forecasting may lose its informative value during crises, nowcasting cannot entirely replace it. Instead, both approaches can complement each other, enhancing policy decisions. The thesis also highlights nowcasting's potential for policy analysis and also its use in science.

The Polish model of the populist party: a new perspective on the populist radical right
Greger, Vojtěch ; Kofroň, Jan (advisor) ; Guasti, Petra (referee)
The Polish model of the populist party: a new perspective on the populist radical right Master's thesis Bc. Vojtěch Greger Abstract The rise of the populist radical right (PRR), a group of parties critical of the established norms of Western liberal democracy, in the 2010s, manifesting itself in events such as Brexit or the illiberal takeover of Hungary, has been a subject of considerable attention both from academics and the general public, and has been viewed with great concern. Academic studies of the PRR have often elevated the nativist elements in such parties' rhetoric while paying considerably less attention to the economic appeals thereof. However, in recent years, literature highlighting the importance of economic deprivation in fomenting support for Eurosceptic and PRR movements has begun to appear. This thesis is predicated on this literature's argument that the electoral successes of the PRR are very often driven precisely by economic deprivation and the discontent stemming from it. To illustrate our argument, we examine the electoral support of the Polish Law and Justice (PiS) party in the 2015 and 2019 elections using ordinary least squares regression (OLS) and geographically weighted regression (GWR). Our findings show that structural economic factors, mainly the share of workers employed in...

Novus ordo seclorum: A Historical Analysis of American Isolationism
Young, Caine ; Kofroň, Jan (advisor) ; Romancov, Michael (referee)
The central tenets of this thesis seek to explain what American isolationist theory is and how it first emerged in the country. Written as follows is a broad analysis of why the specific brand of American isolation had remarkable longevity throughout the foundational years of the early and later stages of the American epoch, even in drastically changing geopolitical conditions. Concurrently, the thesis will seek to question why, and if, specific and seminal geopolitical events represented breaches by the foreign policy elite of the foundational international relations theory of American nonintervention. These events discussed serve as important unifying case study examples of American foreign policy thinking and political and military action more generally. The cases include the Mexican-American War; the Spanish- American War; and the Second World War respectively. Then, current case study examples are discussed to judge the implications of a returning isolationist strain in American political life. After careful consideration of academic literature and analysis of resources spanning written public speeches from leading policymakers, intellectuals, business leaders, and civic minds of their times, as well as raw numerical data research, a combination of foundational principles surrounding offensive...
