Analysis of thermal behavior focused on additive manufacturing of lattice structures from AlSi10Mg
Nosek, Jakub ; Dočekalová, Kateřina (referee) ; Paloušek, David (advisor)
Using Additive manufacturing it is possible to manufacture complicated components, that cannot be manufactured using conventional methods. The typical example is the lattice structure. Fabrication of these structures is complicated, and it is different from the fabrication of bulk parts. Using numerical simulation which can reflect process parameters it is possible to analyze the thermal behaviour of vertical and inclined struts fabrication. Results show that the diameter of struts influences weld track width. This influence is caused by preheating the powder material by previous scanning paths. The final geometry of inclined struts is made in more scanning layers. In this work influence of the start and endpoint of trajectory is described.

Testing of Precise Point Positioning Method
Nosek, Jakub ; Kratochvíl, Radim (referee) ; Machotka, Radovan (advisor)
This diploma thesis deals with the Precise Point Positioning (PPP) method in various variants. The thesis describes the theoretical foundations of the PPP method and the most important systematic errors that affect accuracy. The accuracy of the PPP method was evaluated using data from the permanent GNSS station CADM, which is part of the AdMaS research center. Data of the period 2018 – 2019 were processed. The results of combinations of different GNSS and the results of different observation periods were compared. Finally, the accuracy was verified at 299 IGS GNSS stations.

Effect of layer thickness on critical angle of additively manufactured lattice structures
Nosek, Jakub ; Vrána, Radek (referee) ; Vaverka, Ondřej (advisor)
Aim of this work is to describe the effect of a layer thickness on critical angel of a lattice structures manufactured by SLM technology. The effect of layer thickness was investigated on single struts and on lattice structures made from stainless steel 316L. Better geometrical accuracy could be obtained, if the smaller layer thickness is used. Less attached powder particles on downskins was also observed on lattice structures. Thanks to this thesis, it is possible to determine, if it is meaningful to decrease the layer thickness in order to improve manufacturability of lattice structures even with higher manufacturing time.

Accuracy of Real Time Kinematic Method in Building of Geodetic Control
Nosek, Jakub ; Kuruc, Michal (referee) ; Bárta, Ladislav (advisor)
The aim of this bachelor thesis was to evaluate the accuracy of the RTK method in the creation of point fields. The RTK-measurement was carried out near the Faculty of Civil Engineering, Technical University in Brno, and near Jedovnice, by using the CZEPOS network and the Trimble VRS Now Czech network. These two locations have made it possible to assess the effect of receivers distance to the reference stations on measurement accuracy. At each point, two continuous coordinate records were executed by the RTK method after 10 seconds during 10 minutes. The graphs were compared to the coordinate differences of the pairs of independent measurements. The results of the RTK method were tested against the reference values determined by the common equalization of the measurement results of the fast static method and the terrestrial measurements by the total station using the LSM. The bachelor thesis also includes a comparison of the results of the transfer of spatial coordinates ETRF2000 to S-JTSK using precise global transformation performed by several transformation programs.

Constitutional and Legal Aspects of the Development of the Party System in Chzechoslovakia after 1989
Nosek, Jakub ; Švec, Kamil (advisor) ; Marková, Klára (referee)
This bachelor thesis is focused on democratic transition and forming of pluralist political system at the federal level of Czechoslovak federal state which took its start during so called velvet revolution in November 1989 and meant rejection of previous not competitive model of one party rule which did not accepted real opposition and have only tolerated satellite political parties to Communist party of Czechoslovakia, that did not opposed its monopolist model of government. After fell of the communist regime gradually emerged and crystalized a pluralist party system. First part of this thesis is focused on theory of democratic transition and consolidation subsequently there is space dedicated to the theory of political parties and party systems. Second part is single case study dedicated to description of the Czechoslovak transition with regard to theoretical concepts of the theory of democratic transition and consolidation and through content analysis of relevant laws and constitutional laws are observed emergence and subsequent forming of pluralist party system at the federal level of the Czechoslovak Federative Republic.

New Trends in International Commercial Arbitration
Nosek, Jakub ; Dobiáš, Petr (advisor) ; Brodec, Jan (referee)
New Trends in International Commercial Arbitration Abstract: The purpose of my thesis is to analyze two leading trends in international commercial arbitration. Those trends are (i) the influence of electronic means of communication on arbitration proceedings and (ii) confidentiality and its actual development in respect to implied duty of confidentiality in arbitration proceedings. The main methodology of research was to compare recently revised arbitration rules with its previous wordings (UNCITRAL Rules, ICC Rules, SCC Rules and CAM Rules) and examine changes related to the above enlisted topics. Furthermore diverse sources were used in the thesis such as arbitration rules of different institutions, experts' publications and also e-mail correspondence with representatives of observed arbitration institutions. The thesis is composed of three chapters. The first chapter summarizes actual revisions of observed arbitration rules without making any conclusions. The second chapter describes the influence of modern technologies on arbitration proceedings. The chapter consists of four parts. The first part introduces online arbitration and presents possible ambiguities in this term. The second part focuses on specific stages of arbitration proceedings and analyzes in detail, how those stages are influenced by...

Technical acceptability of witness and participant testimonies at traffic accident
Nosek, Jakub ; Tylšar, Vladimír (referee) ; Semela, Marek (advisor)
This master’s thesis deals with issues of road traffic accidents from the perspective tes-timonies of witnesses of road traffic accidents, especially in terms of the space and time per-ception and in terms of the content development changes during time. This issues are solved at first theoretically, gained knowledge is then used by several real accidents. For each traffic accident was selected several questions important to solve its course and in the testimonies of witnesses and participants have found the answers to these questions. In the responses were monitored technical acceptability and content development of the testimonies during time, and then were made ratings of the technical acceptability of the each answer and score rating of compliance with the previous testimony. This allowed determining for each witnesses or participant and for every traffic accident level of technical unacceptability responses and the level of testimonies content development changes during time.
