Simulation of contrast-agent distribution in a real microvascular system
Schwachulová, Natalia ; Mézl, Martin (referee) ; Jiřík, Radovan (advisor)
The goal of this thesis is to simulate the distribution of contrast agents in a real microvascular system in order to validate methods used in perfusion imagining in DCE-MRI. It contains explanation of principles of the DCE-MRI method and introduction of blood vessels in each of the murine tissue datasets. The thesis resolves around finding graph model, representing blood vessels in used datasets, calculating diameter and respective vascular resistance of each blood vessel, determining direction of blood flow in the blood territory, estimation of impulse residual function of each tissue and creation of generator of concentration curves. Obtained concentration curves are then used to estimate perfusion parameters , and and analyzed using SW PerfLab in order to determine, which pharmacokinetic model is the best to represent each tissue.
Redundancy in data networks
Šoun, Jan ; Pavlíček, Luboš (advisor) ; Beneš, Jiří (referee)
This thesis focuses on redundancy in data networks and on technologies which are used to achieve high availability in network infrastructure. This thesis is based on industry standards published by well-known standardization authorities. One proprietary technology which can effectively replace these standards and simplify the whole network is also presented in more detail. The theoretical part individually describes all such technologies and standards. The practical part deals with an appropriate combination of these technologies and their application in a specific product environment. This work is meant to describe the whole concept of high availability in network infrastructure and should be instrumental in understanding how these technologies are deployed in practice.
