Stability and chaos in nonlinear dynamical systems
Khůlová, Jitka ; Tomášek, Petr (referee) ; Čermák, Jan (advisor)
Diplomová práce pojednává o teorii chaotických dynamických systémů, speciálně se pak zabývá Rösslerovým systémem. Kromě standardních výpočtů spojených s bifurkační analýzou se práce zaměřuje na problém stabilizace, konkrétně na stabilizaci rovnovážných bodů. Ke stabilizaci je využita základní metoda zpětnovazebního řízení s časovým zpožděním. Významnou část práce tvoří zavedení a implementace obecné metody pro hledání vhodné volby parametrů vedoucí k úspěšné stabiliaci. Dalším diskutovaným tématem je možnost synchronizace dvou Rösslerových systémů pomocí různých synchronizačních schémat.

High Precision Reference Position Generator for Motor Control in FPGA
Dvořák, Vojtěch
The paper deals with an architecture of a high precision reference position generator for a motor controller implemented in FPGA. The architecture was developed to achieve high accuracy and tunability with concern to resource efficient implementation in FPGA. Simulations of the proposed generator as well as synthesis results are presented in the paper.

Activity pattern of free-living Ansell´s mole-rat (\kur{Fukomys anselli}) as revealed by automatic radio-telemetry
HAUSTEINOVÁ, Tereza
Social behavior of some species of African mole-rats makes them interesting object of study. Members of multigenerational families were only one pair breeds collectively work on building of their burrow system and obtaining food. Distribution of activity during the day in individual family members may give us a clue of how they manage their work. However, studies monitoring mole-rats in their natural environment are scarce and usually carried out on low number of individuals. Present study deals with outside-nest activity of 16 free-living Ansell´s mole-rats using data obtained by automatic radio-telemetry - method which was used in radio-tracking of mole-rats for the first time. It reveals differences in activity pattern of individual mole-rats and examines how they relate to body mass, sex, reproductive status and affiliation to a family and test whether individuals of the same family tend to be synchronized in their outside nest activity.

Java EE Application Synchronization
Poul, Jan ; Rychlý, Marek (referee) ; Burget, Radek (advisor)
This work deals with the Java EE platform and the bidirectional client-server communication. It presents a design of an application architecture that allows to synchronize the state of applications and their graphical output for a larger number of clients. The final solution contains a sample application that demonstrates the synchronization of connected clients.

Distributed Document Server Based on CouchDB Database
Kanis, Martin ; Burget, Radek (referee) ; Rychlý, Marek (advisor)
Thesis discusses distributed database systems and its advantages and disadvantages. Further, text informs about document database CouchDB, storage of documents, synchronization and CAP theorem. The aim of the thesis is to implement distributed document management system and workflow management system based on CouchDB. The system contains a cluster with three CouchDB nodes with HAProxy in front, which does load balancing. The system allows creation of any document based on the template, manages its life cycle and workflow. It is also possible to create a custom workflow using BRMS rules. The implemented solution simplifies document management and workflow and allows a high degree of customization for the organizations needs.

Circadian system of the retina
Kozel, Tomáš ; Bendová, Zdeňka (advisor) ; Moravcová, Simona (referee)
Most of the known living organisms have developed an evolutionary adaptation to a 24-hour daily rhythm. This rhythm, known as circadian rhythm, can be preserved even in the environment, in which there is no access to light or other synchronizer. The master organ of circadian rhythm is located in the hypothalamic suprachiasmatic nucleus (SCN) and have been considered the only autonomous circadian oscillator for a long time. The new research, however, has doubted this hypothesis by showing the existence of autonomous circadian clock systems independent of SCN. One of these autonomous clocks is the circadian system in the retina. This bachelor thesis reviews current scientific knowledge on the function of mammalian retinal circadian oscillator, most importantly in the field of its localization, connection with the SCN master circadian oscillator and its influence on retinal physiology.

Universal backup
Douša, Daniel ; Pergel, Martin (advisor) ; Fučík, Milan (referee)
The main assignment of job is to solve the problem of colliding access to a shared data store for different types of data backup. The main limitation is the impossibility to run the server software on the shared medium. For this reason, there is a need to find resolutions of conflicts only with using of a shared data space and non-guaranteed direct connections of clients. As part of the work is implemented the solution has preference direct clients with a guarantee in the form of a synchronizing file on a shared medium. Part of the draft solution is to create an application that allows various types of backup (full, differential, synchronization, etc.). The application also allows distributed backup (backup data from multiple location) with synchronization mechanisms. Powered by TCPDF (www.tcpdf.org)
