Russian geopolitics - constants and changes after the split of the USSR
Vosátková, Veronika ; Tomeš, Jiří (advisor) ; Jelen, Libor (referee)
As the diploma's thesis it was chosen the theoretical analysis of the geopolitical position of Russia. The primary objective of this study is the evaluation of current geopolitics of the Russian Federation after the collapse of Soviet Union and outlines its future development. This work tries to answer a few basic questions. What is the current geopolitical situation in Russia, in what direction it develops, and whether we can declare a major shift to any direction. The work is divided into several main parts. Introduction is followed by a theoretical grasp of key concepts and the main actors involved in geopolitics. The other two parts contain an analysis of the relationship of Russia to key actors such as the US and NATO, the EU, China, the near neighborhood in Central Asia and the Transcaucasia and geopolitics of oil and natural gas. The last is practical part, in which the information from the previous sections are applied to specific examples in Russian foreign policy. Keywords: Geopolitics, Russia, eurasianism, foreign policy, the US, the EU, China, Central Assia, NATO, energy policy, oil, natural gas

Time factor in the managerś work
Rácová, Nikola ; Štůsek, Jaromír (advisor) ; Zdeněk, Zdeněk (referee)
The diploma thesis deals with time management in work of three managers.
The thesis consists of theoretical and practical part. The theoretical part is based on study of scientific literature. It is focused on management, managers personality, managers functions and roles. Thereafter, time management techniques and methods are described. Information from theoretical part provides a complex base for the practical part.
In the practical part, the organization and managers, who are the subject of this thesis are described. For the time management analysis was used time frame, forms for analyzing interference and forms for identifying the major time consumers. Furthermore, individual conducted interviews with each manager were made. The interview revealed the managers attitude to the importance of the time factor in their managerial work.
On the basis of information obtained from analyzes and interview, the shortcomings were discovered. Recommendations for elimination of shortcommings were suggested together with recommendation for more efficient use of time.

Stuchlík, Martin ; Pánek, Pavel (advisor) ; Jadrná, Monika (referee)
This thesis focuses on the time factor in management manager. The main objective is to analyze time management of two executives in the company Compedium, s.r.o.
and then propose measures for improvement. The operational objective is writing
a literature review, performing structured interviews and assembly time frames

The time factor in management executives
Faktor, Vladimír ; Štůsek, Jaromír (advisor) ; Toth, Daniel (referee)
The diploma thesis is focused on the effectivity of time management skills of three chosen managers. The thesis is split into two parts.
The first part of the thesis provides theoretical basics of time management, basic terminology and methods of time management are layed out for further use in the second part of the thesis.
The second part of the thesis consists of guided interview, time frames and questionnaire which are used to identify individual approaches and problems in time management of three chosen managers, who are representing each level of management (lower, middle and top level) and come from various types of business organizations.
Based on the data provided by the second part of the thesis, the problematical parts of the time management are identified for each manager and recommendations are offered to each individual.

Possibilities of QoS algorithms simulation and optimization
Charvát, Ondřej ; Číka, Petr (referee) ; Krajsa, Ondřej (advisor)
The bachelor's thesis deals with problematics of data transmission control in converged networks which is implemented there to offer telecommunication services in desired quality. Theoretical part of the thesis provides an overview of measurable parameters and lists factors by which they are affected. It discusses different levels of services offered and finally techniques used for it's provisioning as they are implemented in network appliances. In practical part a model of network with QoS implementation is constructed in simulation software Simulink. There are several traffic flows running in the simulated network which has different demands on transfer quality such as telephony or bulky file transfer. There is graphical user interface programmed in Matlab enviroment by which it is possible to alter QoS settings in the model and observe effect on achieved parameters of running data transfers. All simulation results are also displayed on the user interface. User may set all parameters manualy or let the software optimize settings according to prefered criterion, i.e. packet loss. In such way model demonstrates how changes in QoS configuratinon affects quality of services being transferred. The whole model is constructed in a way to be easily reconfigured in case of future use. It is possible for expample to add more traffic or to extend the model to larger network by using predefined blocks.

Experimental network for QoS support testing
Fogl, Miroslav ; Mácha, Tomáš (referee) ; Novotný, Vít (advisor)
The work specifies problems with support of qualitative requirements in IP network services on the network and link layer. There are also described options of qualitative support of individual networking components in the UTKO laboratory (routers, L3 switches). Created experimental network is loaded by various types of service (VoIP, FTP, HTTP, Video). Data services realization is ensured by available terminals (IP phones, IP cameras, IP video-phones, servers, client stations). Metering is targeted on the manipulation with packets in the router. Options which Cisco router offers are verified by packet analysis. Available methods of dropping are compared on the base of metering and evaluated. Optimal handling with output queue after metering in experimental network is LLQ mechanism. It is able to prefer packets according to their priority in the IP header. Further the difference of link overloading by huge dataflow after QoS policy using is simulated. To reach availability of data services in the whole network is necessary to deal with mechanisms for qualitative services support in all the network components in the network.

Design of Switch Used in Modern Communication Networks
Mojžiš, Ľubomír ; Novotný, Bohumil (referee) ; Škorpil, Vladislav (advisor)
This diploma thesis deals with switching components of modern communication networks. A switch architecture focused on the quality of service is described in this paper and there are two switch models designed and simulated in the simulating program MATLAB-SIMULINK. The first model is based on classic switching and the other one is controlled by neural network. A laboratory exercise suitable for communication networks education is created in this paper on the basis of designed models.

Switch optimization in converged network
Švec, Adam ; Sobek, Jiří (referee) ; Škorpil, Vladislav (advisor)
Switch Optimization in a Converged Network thesis discusses the role of the Ethernet switch in the network. It describes differences between the switch and the hub in the network and the impacts on the collision domain size. In the converged network, priority data switching according to their origin and thus the qualitative point of view is also addressed - e-mails, voice services and multimedia will each behave differently. A real element, switch L3 - a switch with services quality support - is mentioned. The tool Matlab - Simulink is briefly described and a functional simplified model of the ethernet switch was created. Furthermore, the topic was used as a theme for a laboratory task in the subject Services of Telecommunication Networks. A model for Simulink and an example of the laboratory protocol for the created task are attached to the thesis.
