Empirical Estimates in Stochastic Optimization: Special cases
Kaňková, Vlasta
Classical optimization problems depending on a probability measure belong mostly to nonlinear deterministic optimization problems that are relatively complicated. On the other hand, these problems fulfil very often "suitable" mathematical properties guaranteing the stability (w.r.t. probability measure) and, moreover, giving a possibility to replace the "underlying" probability measure by an empirical one to obtain "good" stochastic estimates of the optimal value and the optimal solution. Properties of thess estimates have been investigated mostly for standard types of probability measures with suitable (thin) tails and independent random samples. However distributions with heavy tails correspond to many economic problems and, moreover, many applications do not correspond to the "classical" problems. The aim of the paper is, first, to try to recall stability results including also heavy tails and more general problems.

Multicriteria games
Tichá, Michaela ; Dlouhý, Martin (advisor) ; Lachout, Petr (referee) ; Čičková, Zuzana (referee)
Theory of multicriteria games is a special field of game theory, when one or more players have at least two payoff functions and want to maximize simultaneously. The work introduces a number of new findings. It examined the concept of finding equilibria in pure strategies in noncooperative multicriteria game. It is possible to find all the equilibria in pure strategies by full search and solving two linear programs for each point. Furthermore, two linear programs are formulated for verifying that a selected point is the equilibrium of the game or not. In the noncooperative games is also introduced the concept that with knowledge of the equilibrium of bimatrix game determines preferences of the players. Although finding the equilibrium point of the bimatrix game is nonlinear problem, finding the preferences is linear problem. The latest findings in the noncooperative games is a generalization of the concept that solves multicriteria game by assigning weights to each criterion of each player. The work demonstrates that it may not be necessarily linear weights, but it can be more general function that describes the player's preference. The remaining part is devoted to knowledge in cooperative games. There is considered that the players know their preferences and are able to express them by weights. The game with known preferences is defined and solved with the use of bargaining theory. Then it is generalized to a case where players have more payoff functions, from which they can choose. Finally, the multicriteria case of voting game is defined. It is designed completely new concept, which selects the winning coalition in the voting game. This concept is then applied to the real situation after the elections to the Chamber of Deputies in 2013.

FAUST AND JOB´S
Slezáková, Kateřina ; ULLRICHOVÁ, Daria (advisor) ; SÍLOVÁ, Zuzana (referee)
This thesis examins the nature of Faust’s inner ambivalence in the context of modern times. It tries to identify the basic traits leading to the feeling of emptiness. The authoress uses comparing the dramatic character of Faust with his biblical prototype of Job and one of the most successful entrepreneurs today Steve Jobs. Based on the comparison she contemplates the validity or mutation of the drawing theses nowadays. In the second part the authoress reflects the production of the project of Faust. Due to her specialization in the field of dramaturgy she pursues especially the process of the selection of particular dramatic situations, adjustments of dramatic text and the choice of suitable staging means.

Stejskalová, Klára ; Skalický, Milan (advisor) ; Martinková, Jaroslava (referee)
The aim of this study is to document the floristic species diversity through research in the natural reserve Miletinska bazantnice. Documentation was carried out on the territory concerned during the growing season of 2015. There was a determination of vascular species. The research was mainly focused on endangered and protected species.
The whole area is part of sites of European importance under the Habitats Directive Natura 2000 Miletinska bazantnice was declared a nature reserve in 1954 with an area of 75, 43 hectares and is part of a small-scale specially protected area. Typical features of the area are remnants of natural Podzvicinsko geobiocenosis and therefore the reason for its protection.
Further it describes the history, characteristics of the territory and the natural conditions that are typical for the locality. These include soil science, climate, hydrological, geomorphological, geological and phytogeographical. On the territory of the nature reserve are recorded two memorial trees. It´s oaks (Quercus robur) called Zizkovy duby.
At present territories were found in protected and endangered species and classified under the Red and black list of vascular plants of the Czech Republic (Grulich, 2012) and Decree of the Ministry of Environment of the Czech Republic no. 395/1992 Coll. Into the category of rare taxa that require additional attention include species such as Carex otrubae, Cerastium lucorum, Daphne mezereum, Galium boreale, Listera ovata and Primula veris. The only species Platanthera bifolia is ranked in the category of endangered under both the Red and black list of vascular plants in the Czech Republic and under Decree.
In the field survey, attention was also paid to invasive species, sorted by Catalogue of alien plants of the Czech Republic (Pyšek et al., 2012) and categorized archeophytes (Arctium tomentosum, Cirsium arvense, Convolvulus arvensis, Chelidonium majus)
and neophytes (Arrhenatherum elatius, Impatiens parviflora) and described their risks (Mlíkovský and Stýblo, 2006)

Packet Classification Algorithms
Puš, Viktor ; Lhotka,, Ladislav (referee) ; Dvořák, Václav (advisor)
Tato práce se zabývá klasifikací paketů v počítačových sítích. Klasifikace paketů je klíčovou úlohou mnoha síťových zařízení, především paketových filtrů - firewallů. Práce se tedy týká oblasti počítačové bezpečnosti. Práce je zaměřena na vysokorychlostní sítě s přenosovou rychlostí 100 Gb/s a více. V těchto případech nelze použít pro klasifikaci obecné procesory, které svým výkonem zdaleka nevyhovují požadavkům na rychlost. Proto se využívají specializované technické prostředky, především obvody ASIC a FPGA. Neméně důležitý je také samotný algoritmus klasifikace. Existuje mnoho algoritmů klasifikace paketů předpokládajících hardwarovou implementaci, přesto však tyto přístupy nejsou připraveny pro velmi rychlé sítě. Dizertační práce se proto zabývá návrhem nových algoritmů klasifikace paketů se zaměřením na vysokorychlostní implementaci ve specializovaném hardware. Je navržen algoritmus, který dělí problém klasifikace na jednodušší podproblémy. Prvním krokem je operace vyhledání nejdelšího shodného prefixu, používaná také při směrování paketů v IP sítích. Tato práce předpokládá využití některého existujícího přístupu, neboť již byly prezentovány algoritmy s dostatečnou rychlostí. Následujícím krokem je mapování nalezených prefixů na číslo pravidla. V této části práce přináší vylepšení využitím na míru vytvořené hashovací funkce. Díky použití hashovací funkce lze mapování provést v konstantním čase a využít při tom pouze jednu paměť s úzkým datovým rozhraním. Rychlost tohoto algoritmu lze určit analyticky a nezávisí na počtu pravidel ani na charakteru síťového provozu. S využitím dostupných součástek lze dosáhnout propustnosti 266 milionů paketů za sekundu. Následující tři algoritmy uvedené v této práci snižují paměťové nároky prvního algoritmu, aniž by ovlivňovaly rychlost. Druhý algoritmus snižuje velikost paměti o 11 % až 96 % v závislosti na sadě pravidel. Nevýhodu nízké stability odstraňuje třetí algoritmus, který v porovnání s prvním zmenšuje paměťové nároky o 31 % až 84 %. Čtvrtý algoritmus kombinuje třetí algoritmus se starším přístupem a díky využití několika technik zmenšuje paměťové nároky o 73 % až 99 %.
