Composite printing for 3D FDM printer
Műller, Jakub ; Sliwková, Petra (referee) ; Zemčík, Oskar (advisor)
This diploma thesis deals with the study of 3D printing based on the FDM method. This method focuses on the possibility of using two extruders it means that the composite parts can be printed. This diploma thesis describes the available variants of composite printing currently on the market. Based on the gained knowledge and the availability of 3D printers and software, individual variants of composite parts were printed. A tensile test was performed on these samples to determine the strength characteristics. Additionally, compatibility and adhesion of two selected materials were tested. Based on the testing is made an evaluation of the achieved results, effectiveness and feasibility.
Current methods for geolocation of Internet hosts
Doležel, Pavel ; Müller, Jakub (referee) ; Balej, Jiří (advisor)
This bachelor work deals with IP geolocation, which means the estimation of geographical location of unknown host in the Internet. The aim of my thesis was to make a delay measurement in PlanetLab Network and then with the use of GeoPing technique estimate the real location of the target. The main part of this work is focused on several different delay-based methods, especially GeoPing which employs „Nearest Neighbor in Delay Space“ algorithm in order to exploit the relationship between network delay and geographic location. Base ground for GeoPing is a database of the machines at known location. This database is composed of 9 probe machines, 260 hosts is used like a landmarks and targets. Estimation of unknown geographical location was done on 60 hosts.
Localization of nodes in Internet using Lighthouses system
Smrčka, Lukáš ; Müller, Jakub (referee) ; Komosný, Dan (advisor)
The thesis is focused on the localization of stations in the Internet with the help of artificial coordinate systems. These systems can be used to estimate the delay value of RTT between individual stations. The estimated delay value can e.g. help the station to choose an optimal second station for communication between two stations without the necessity to measure these values, which reduces the load of the net. The first part of the thesis describes systems that predict the delay and explains how the methods Vivaldi, Kings, GNP and Lighthouses work. The next part of the work gives basic information about environment where the chosen method shall be implemented. The final part defines both the Lighthouses method and a program designed to be used in the experimental PlanetLab network and it also evaluates achieved accuracy of the estimation.
Optimization of signalization channel for Internet television
Matej, Michal ; Balej, Jiří (referee) ; Müller, Jakub (advisor)
The aim of this Bachelor's thesis is to propose a mechanism for optimizing the signaling channel in case of Feedback Target overload in hierarchical aggregation tree. Consequently to this verify the implementation of this mechanism in simulation environment of Java and to achieve the balance load among Feedback Targets. The theoretical part discusses the significant differences between traditional television transmission and television transmitted via the IP protocol, the methods of data transmission in IP network and key protocol called Tree Transmission Protocol working on the application layer of TCP/IP model. In this part there are explained the concepts of hierarchical aggregation of feedback channel such as Feedback Target Manager, Feedback Target, as well as packets FTD, FTS, and FTI.

The thesis contains installation and configuration manual for applications CoDeploy, Plush and Nebula, description of their functions and practical usage in PlanetLab network environment. Section about graphic user interface Nebula deals with module for XML application development. Part with PlMan software alternative for Windows is also completely made out. Ending of the thesis is focused on CoMon monitoring system, its functions, elements and practical application in network.
Node localization on the Internet using domain name system
Dvořák, Petr ; Müller, Jakub (referee) ; Komosný, Dan (advisor)
This paper describes various systems that are used to predict delay among nodes . It focuses on systems using for prediction delay artificial coordinate systems, and on the systems, which use physical measurements of delay. Primarily, however, it deals with the King method, which uses the system for translation of domain names - DNS (Domain Name System) to predict the delay. Next, the principle of the King method is outlined in detail. Practical part includes a description of the two created simulations in program Matlab. The first application described simulates the King method principle. The second simulation is then tasked with creating 2D geometric space in which nodes and DNS servers are randomly generated. The result is dependence of RTT prediction accuracy on the number of randomly generated DNS servers. Based on this dependency the method King is compared with other methods in the end.
Synchronized data transfer of signalling in IPTV
Figurny, Roman ; Karásek, Jan (referee) ; Müller, Jakub (advisor)
The task of Bachelor's thesis has been to develop synchronizing mechanism for signaling servers, called Feedback Targets, in hierarchical structure of the feedback tree. Then verify the function of this designed synchronizing mechanism in simulation developed in Java. Using this synchronizing mechanism to shorten the time needed to travel the signaling packets trough the feedback tree and using this to obtain better reaction to possible network junction or significant packet loss while distributing multimedia data while using IPTV. In theoretic part of the thesis there are described basic protocols like RTCP, RTP and TTP. Then are described methods for packet sending in network (multicast, unicast and broadcast). The basic piece of knowledge about IPTV, its distribution and differences between IPTV and classic internet media streaming are described. Also basic terms like Feedback Target, Feedback Target Manager and FTI, FTS and FTD packets are described as well.
Voting service for IPTV
Menclík, Tomáš ; Karásek, Jan (referee) ; Müller, Jakub (advisor)
This thesis deals with a concept and implementation of voting service for IPTV. Implementation of this service is executed in programming language Java and uses programming structures, which were already done. These structures are intended for simulation of propertys of tree transmition protocol. Outside of the concept and implementation of voting service, there are presented protocols, which IPTV uses for communication. And also voting service, implemented in this thesis, uses their propertys. There are also mentioned dierences between outlined and implemented voting service as the implementation does not keep strictly the concept of the voting service.
