Pecháček, Jan ; Trampota, Tomáš (advisor) ; Benda, Josef (referee)
Bachelor thesis "Image of the Police of the Czech republic in Mladá fronta Dnes and Právo daily newspapers" analyses the way of presentation of the Police of the Czech republic in Mladá fronta Dnes and Právo daily newspapers in a distance of ten years using a content analysis. It explores and compares years of 1996 and 2006 and documents development and movement in the way of imagery of this state institution. The thesis deals with the situation in the Czech society after the year of 1989 from the perspective of police work and theme in its introduction. There are theoreticly described the method of research and its process in further parts and the results analysis in the end of the thesis.

Placement of the Criminal police within the police forces in Czechoslovakia era after 1948
Lipš, Martin ; Mücke, Pavel (advisor) ; Wohlmuth, Petr (referee)
This diploma thesis is about forensic science, criminal acts and organization of protective security units investigating such activities in the former Czechoslovakia between the years of 1948 and 1969. It also indicates how the criminal activity was developed in the Czechoslovakia and how the former police departments took part in the investigation. The course of the investigation, the crime investigation methods, and the theoretical bases of that time, on which the forensic science was based, are thoroughly described on specific serious crimes. The thesis mainly draws from the primary resources such as archive research, notably from the Security Service Archive's materials, and the periodical press. Keywords Forensic science in the Czechoslovakia, "Department of Public Security" (Veřejná bezpečnost), murder, criminal activity, criminal offence in the Czechoslovakia, Security Services Archive

Camera systems in public spaces - ensuring safety or endangering privacy?
Tokárová, Michaela ; Kysela, Jan (advisor) ; Mlsna, Petr (referee)
of the Thesis This thesis deals with a problem of surveillance in public spaces. In the introduction it was specifies that the main aim of the thesis is to give a complex view on the topic of surveillance cameras in public areas from the constitutional law perspective. In the Czech republic, no further discussion has developer and legislatively, the issue is only regulated by the personal data protection law. And this regulation is not even complex, it only deals with CCTV kind of cameras, excluding the ones without storing the data. In the beggining of the thesis I explai right to privacy and under which conditions it can be limited. The core of the paper deals with camera systems themselves, their use, pros, cons and effecitivity. Later I describe opinions of some offices and states on the topic. Proportionality test of the constitutional court and the ECHR to balance right to privacy with the state responsibility for public safety was conducted in the last part of the thesis. The advantage of CCTV is that thez provie impression of security to the citizens. They discourage potential perpetrators and help to maitain security of individuals, property and public interests, as well as detection, prevention and conviction of criminals. It helps securing proofs for future trials. On top of that, CCTV...

Armed Violence - Gangs Maras - Challenge and Threat to the National State in El Salvador, Guatemala and Honduras
Líčková, Kateřina ; Kozák, Kryštof (advisor) ; Krausz Hladká, Malvína (referee)
The three countries of Central America El Salvador, Guatemala and Honduras, which form the so-called Northern Triangle, are among the most violent countries in the world. One of the actors of local violence are gangs maras. This thesis "Armed Violence - Gangs Maras - Challenge and Threat to the National State in El Salvador, Guatemala and Honduras." deals with the problem of transnational gangs Mara Salvatrucha (MS- 13) and Barrio 18 (M-18) and with the interaction between maras and society. The aim of this thesis is to understand the complexity of the maras phenomen and to provide its detailed analysis. Maras were originally founded in Los Angeles by Mexican (M-18) and Salvadorian (MS-13) immigrants. As a result of tighter U.S. immigration policy, some members were deported to their country of origin - to the northern triangle countries. The strong cultural identity of maras appealed to thousands of young people and helped in the rapid expansion of the gangs. Maras are currently regarded as one of the greatest threats to the Central American region. Since 2003 the governments have led a repressive campaign to combat maras, which is supported by media and which sought to involve military in police actions. However, the politics of firm hand haven't had desired effect. Labeling maras as the main...

Gradient Boosting Machine and Artificial Neural Networks in R and H2O
Sabo, Juraj ; Bašta, Milan (advisor) ; Plašil, Miroslav (referee)
Artificial neural networks are fascinating machine learning algorithms. They used to be considered unreliable and computationally very expensive. Now it is known that modern neural networks can be quite useful, but their computational expensiveness unfortunately remains. Statistical boosting is considered to be one of the most important machine learning ideas. It is based on an ensemble of weak models that together create a powerful learning system. The goal of this thesis is the comparison of these machine learning models on three use cases. The first use case deals with modeling the probability of burglary in the city of Chicago. The second use case is the typical example of customer churn prediction in telecommunication industry and the last use case is related to the problematic of the computer vision. The second goal of this thesis is to introduce an open-source machine learning platform called H2O. It includes, among other things, an interface for R and it is designed to run in standalone mode or on Hadoop. The thesis also includes the introduction into an open-source software library Apache Hadoop that allows for distributed processing of big data. Concretely into its open-source distribution Hortonworks Data Platform.
