Auto Rate Fallback (ARF) algorithm for wireless connection according to the standard 802.11g.
Zarković, Luka ; Mašek, Pavel (referee) ; Kubánková, Anna (advisor)
This bachelor thesis deals with problems of adaptation protocols and their implementation. In this bachelor thesis are described physical and MAC layers of standard 802.11g and theoretical analysis of adaptation protocols ARF and AARF. Further, the thesis describes the process of creating a network model suitable for testing and verifying the properties of adaptive protocols in the simulation environment NS-3 (Network Simulator 3). In the last part, the simulation results are described and processed into suitable graphs.

OpenSCAP Report: A Tool for Visualizing Security Compliance Inspection Results
Rodák, Jan ; Rozman, Jaroslav (referee) ; Drga, Jozef (advisor)
Cílem práce je vyvinout nástroj pro prezentaci výsledků bezpečnostního skeneru OpenSCAP. SCAP skenery používají standardizované vstupní a výstupní formáty, které nejsou čitelné člověkem. Cílem nástroje je prezentovat výstup SCAP skeneru ve formě interaktivního reportu, který pomůže najít hlavní příčinu selhání bezpečnostních požadavků. Dovolí uživatelům porozumět složení příslušných bezpečnostních kontrol. Report umožní uživatelům OpenSCAP i vývojářům bezpečnostních profilů ladit jejich kontroly. Poskytne pohled na vztahy mezi jednotlivými kontrolami a pomůže pochopit kontext těchto kontrol v rámci bezpečnostních profilů SCAP.

Charakterizace vlivu senescence na indukci a regulaci smrti nádorových buněk
Nováková, Gita ; Anděra, Ladislav (advisor) ; Truksa, Jaroslav (referee)
4 Abstract Senescence is a specific cell state distinquished by cessation of cell division and proliferation and changes in gene expression. Normal cells enter senescence after distinct number of cell divisions or in case of an unrepairable damage. Senescence in cancer cells can be induced by subliminal stress as sublethal treatment with certain drugs. Senescent cancer cells persist in the tissue and may secrete a number of factors and nutrients affecting surrounding cells. Senescence can thus change the response of cancer cells to various apoptogens during cancer therapy. In this study, we focused on the elucidation of presumed differences between normal proliferating and senescent cancer cells in their response to selected apoptogens. Implementing bromodeoxyuridine (BrdU)-mediated replication stress in cancer cells derived from pancreatic (PANC-1) or mesothelioma (H28) tumors, we efficiently forced these cells to acquire senescent phenotype. We document that these senescent cells gain higher resistance to combined TRAIL and homoharringtonine (HHT) treatment and enhance sensitivity to other apoptogens such as FasL, camptothecin and mVES. These cells also showed increased expression of anti-apoptotic protein c-FLIP in senescent cells and changes in the expression of some Bcl-2 family proteins....

Structure- and sequence-based identification of functionally important amino acids in a protein family
Peclinovská, Iveta ; Novotný, Marian (advisor) ; Pleskot, Roman (referee)
A group of small GTPases consist of over twenty protein families in the super class P-loop. It has a very diverse cell functions. Small GTPases regulate the formation of vesicular follicles, cytoskeleton and nuclear transport. They participate also on cell proliferation and signaling. The aim of my work is to find important amino acids that define family and distinguish each other. I focus on families Arf, Rab, Ran, Ras and Rho. At the Rho family I am also devoted to classes Rho, Rac and Cdc42. Amino acids are identified using bioinformatic programs selected Consurf and Sca5. The objective is also to test P2RANK specialized tool developed at the Charles University in Prague that predict ligand binding sites from protein structure in different families. Founding amino acids can have a big role in the functional divergence of individual families and classes of small GTPases and can be the basis for future study example for the proliferation of cancerous cells. 1.1 Keywords Powered by TCPDF (www.tcpdf.org)
