Computer Networks Based On Vyos And Cisco Ios Operating Systems
Jalovecky, Denis
český
This thesis focuses on configurations and issues of network protocols in operating systemsof Cisco IOS and VyOS routers. One of the main goals include choosing the most appropriate emulatorand installation of this emulator in virtual enviroment. The thesis also describes the propertiesand differences of protocols and their application in the network operating systems mentioned above.After learning about possibilities of emulations, two scenarios, in which the protocols were appliedand analyzed, were created. These scenarios meet standard of a lab excersise which takes around oneand a half hour. The most frequent issues and their solutions are mentioned as well.

Design And Construction Of Measuring Apparatus For Lightning Research
Kirsanov, Ivan
český
The present work is concerned with the problems of measuring the electric field intensityin the earth’s atmosphere. Within the article theoretical principles of circulating charges in theatmosphere leading to the increasing of the electric field strength are discussed. The minimummathematical apparatus for calculating the required quantity is given. The principle of operation ofthe electrostatic flux meter type device is explained. Special attention has been given to subjects asfollows: sensor noise clipping and an example of the project of an active filter for determiningrequired measurement frequency.

Polygon Scenarios Of The Czech Distribution Network
Bohačík, Antonín
český
This work is focused on the design and implementation of communication scenarios to createdpolygon that simulates the data communication of the transmission network of the Czech Republic.Scenarios represent usual but also unusual situations in which real stations of the transmissionsystem may be. Furthermore, the assumptions are described here to simulate the created scenariosor the criteria and ranges that the station must cover during the simulation.

Monitoring The Parameters Of Cells Migrating In Pseudo-3d Extracellular Matrix
Zumberg, Inna
český
Cell migration plays an essential role in a number of biological processes, such as embryogenesis,the immune response, wound healing and inflammation. Most research regarding cellmigration is based on experiments using two-dimensional (2D) cell cultures, and the detailed molecularand biophysical mechanisms of these processes are already well known. However, muchless is known about cell behaviour in the three-dimensional (3D) environment of living tissues.Pseudo-three-dimensional (pseudo-3D) cell cultures bridge the gap between 2D and 3D geometriesand combine their advantages. This review presents the quantitative evaluation of human mesenchymalstem cells (hMSCs) migration parameters in pseudo-3D artificial extracellular matrix(ECM) of various compositions.

Fenomén zastavování krajiny - urban sealing
Šerek, Jiří
český
Vedle fenoménu urban sprawl, který byl již poměrně bohatě popsán a diskutován, stojí ještě jeden jev, který s předchozím úzce souvisí. Jedná se o tzv. urban seailng, neboli zastavování krajiny. Tento termín zachycuje veškerý typ výstavby vedoucí k přeměně přírodních propustných povrchů na nepropustné. Článek se bude zabývat charakteristikou problému, metodikami měření a současným stavem ochrany v rámci České republiky. Besides the fully described and discussed phenomenon of urban sprawl, there is another phenomenon closely linked to the previous one. The so-called urban sealing or urban soil sealing. This term captures any type of construction that leads to the conversion of natural permeable surfaces to impermeable ones. The article will describe the characteristics of the problem, accesible methods of measurement and current state of protection within the Czech Republic.
