Query-by-Example Spoken Term Detection
Fapšo, Michal ; Matoušek, Jindřich (referee) ; Metze, Florian (referee) ; Černocký, Jan (advisor)
Tato práce se zabývá vyhledáváním výrazů v řeči pomocí mluvených příkladů (QbE STD). Výrazy jsou zadávány v mluvené podobě a jsou vyhledány v množině řečových nahrávek, výstupem vyhledávání je seznam detekcí s jejich skóre a časováním. V práci popisujeme, analyzujeme a srovnáváme tři různé přístupy ke QbE STD v jazykově závislých a jazykově nezávislých podmínkách, s jedním a pěti příklady na dotaz. Pro naše experimenty jsme použili česká, maďarská, anglická a arabská (levantská) data, a pro každý z těchto jazyků jsme natrénovali 3-stavový fonémový rozpoznávač. To nám dalo 16 možných kombinací jazyka pro vyhodnocení a jazyka na kterém byl natrénovaný rozpoznávač. Čtyři kombinace byly tedy závislé na jazyce (language-dependent) a 12 bylo jazykově nezávislých (language-independent). Všechny QbE systémy byly vyhodnoceny na stejných datech a stejných fonémových posteriorních příznacích, pomocí metrik: nesdružené Figure-of-Merit (non pooled FOM) a námi navrhnuté nesdružené Figure-of-Merit se simulací normalizace přes promluvy (utterrance-normalized non-pooled Figure-of-Merit). Ty nám poskytly relevantní údaje pro porovnání těchto QbE přístupů a pro získání lepšího vhledu do jejich chování. QbE přístupy použité v této práci jsou: sekvenční statistické modelování (GMM/HMM), srovnávání vzorů v příznacích (DTW) a srovnávání grafů hypotéz (WFST). Abychom porovnali výsledky QbE přístupů s běžnými STD systémy vyhledávajícími textové výrazy, vyhodnotili jsme jazykově závislé konfigurace také s akustickým detektorem klíčových slov (AKWS) a systémem pro vyhledávání fonémových řetězců v grafech hypotéz (WFSTlat). Jádrem této práce je vývoj, analýza a zlepšení systému WFST QbE STD, který po zlepšení dosahuje podobných výsledků jako DTW systém v jazykově závislých podmínkách.

Intrusion Detection in Network Traffic
Homoliak, Ivan ; Čeleda, Pavel (referee) ; Ochoa,, Martín (referee) ; Hanáček, Petr (advisor)
Tato práce se zabývá problematikou anomální detekce síťových útoků s využitím technik strojového učení. Nejdříve jsou prezentovány state-of-the-art datové kolekce určené pro ověření funkčnosti systémů detekce útoků a také práce, které používají statistickou analýzu a techniky strojového učení pro nalezení síťových útoků. V další části práce je prezentován návrh vlastní kolekce metrik nazývaných Advanced Security Network Metrics (ASNM), který je součástí konceptuálního automatického systému pro detekci průniků (AIPS). Dále jsou navrženy a diskutovány dva různé přístupy k obfuskaci - tunelování a modifikace síťových charakteristik - sloužících pro úpravu provádění útoků. Experimenty ukazují, že použité obfuskace jsou schopny předejít odhalení útoků pomocí klasifikátoru využívajícího metriky ASNM. Na druhé straně zahrnutí těchto obfuskací do trénovacího procesu klasifikátoru může zlepšit jeho detekční schopnosti. Práce také prezentuje alternativní pohled na obfuskační techniky modifikující síťové charakteristiky a demonstruje jejich použití jako aproximaci síťového normalizéru založenou na vhodných trénovacích datech.

Vývoj metodologické a technologické platformy pro neinvazivní odhad fenolických látek v listech a bobulích
ŠEBELA, David
Plant optical signals can serve as important source of information about biochemical and physiological processes in plants. These signals are influenced by compounds synthesized by plants during primary or secondary metabolism and thus, can also serve as their qualitative and quantitative indicators. Light reaching plant surface (leaf or fruit) can undergo three main pathways- it can be (i) reflected, (ii) absorbed or it can (iii) transmit through plant material. The probability of these three processes depends on particular wavelength of incident irradiation and on the morphological characteristics of plant tissues themselves. As such, plant contains various spectrum of photosynthetic pigments and fluorescent compounds which can either reflect, absorb or pass incident irradiation through at specific wavelengths. Biophysical techniques working with these optical properties of plant pigments and/or other compounds have become universal and common tool in basic and applied research. To quote some example, chlorophyll fluorescence imaging, UV induced fluorescence or spectroscopic techniques are on the top of interest thanks to its non-invasive nature, allowing maintain the integrity of measured cells or the whole plant constituents. The main aim of this thesis is to provide a comprehensive study on the possibility of non-invasive monitoring of phenolic compounds in the leaves and fruits.

The contributions of the sections (NACE-CZ) to the creation of gross value added
BEDNÁŘOVÁ, Monika
The aim of this thesis was to evaluate the contributions of the sections (NACE-CZ) to the creation of gross value added. The first part of this thesis described the theoretical concepts relating to national economic gross value added. Analytical processes were used for the calculations, which may be used only if we are dealing with an additive link between individual factors. The sections' contributions to the creation of national eco-nomic gross value added were evaluated in the practical part, on the basis of the proc-esses set forth in the methodology. In the given time horizon, contributions by institu-tional sectors and groups of sections classified according to the level of technology showed a certain dependency on the actual economic cycle. Although the strongest in-stitutional sector is non-financial enterprises, they were the ones most affected during the crisis period, together with government institutions. On the contrary, the financial institution sector showed a strong position during the crisis period. In terms of the grouping of the sections according to the level of technology, the greatest contribution to national economic gross value added is by groups B1 and B2. The influence of the economic cycle was noted in all the groups but, according to the results, group C did not react quite as sensitively as the other groups.

THE DRAMATICAL SCRIPT AS A NECESSARY BASIS FOR SPACIAL REALIZATOIN
Tretiag, Štěpán ; KORČÁK, Jakub (advisor) ; HRBEK, Daniel (referee)
Using the concrete examples of my practical bachelor work my intent is to retrospectively describe and reflect on our scenic realization of the play Missing by south-African author Reza de Wet. The essence of a modern dramatic direction is to perceive the script of a play as a model which becomes a basis for its interpretation and the subsequent staging of the play. It is the process from the initial interpretation to final scenic realization I wish to focus on in my work.In the first part I will be dealing with creation of a physical space, that being stage design. I will try to capture what lead us to its final shape and how the basis for that can be found in the script of the play as well as the potential capability of the physical space to become a dramatic space. Its ability to create a platform for the actors to proceed from and how can it provoke them into acting, in particular. In the second part I will be dealing with the dramatic space, ergo the spacial expression of relationships and themes. I will proceed again retrospectively, focusing on how we managed to achieve the stage image which is functioning as a materialized metaphor. I will focus mostly on non-verbal actions, but with regard to the fact, that dramatical script is the basis for our realization of the play.

Kloiber, Michal ; Bláha, Jiří ; Hrivnák, Jaroslav ; Buzek, Jaroslav ; Kunecký, Jiří ; Hasníková, Hana
The survey described in this report contains the condition assessment of the truss of the Church of Holy Spirit in Telč. The stimulus for the survey report was an order from the parochial congregation ČCE in Telč. The order included a request to assess the condition and identify the extent of wood-decaying damage to the truss of the Church of the Holy Spirit in Telč, focusing on the location of the critical spots, the classification of the damage degree, the determination of the extent of hidden damage using non-destructive devices, and the specification of the wood damage cause, including drawing of the results in the documentation on the current truss condition. Based on the results, specific procedures of repair measures were proposed and the elements proposed for the reconstruction were sketched in the documentation.

The Importance of the Fundraiser in a Non-profit Organization
STARÁ, Radka
The main theme of the bachelor work is the importance of the fundraiser in a non-profit organization. It defines the term fundraising, its principles, forms and methods, the work of a fundraiser in a non-profit organization.The work characterizes nonprofit organizations, their legal status and field of activity. There are also information about activities, which improve economy and financial situation of these organizations. In the practical part of my work I have analyzed the way of financing a non-profit organization Junak- Czech scout, Centre Pod Kleti Holubov z.s. I am comparing in this part the way of fundraiser work on the local and state platform. The facts here available are drawn from the public web pages of this organization and also from the account keeping documents of its local center. At the conclusion of my work I am assessing the effectiveness of fund raising plan and its strategy and also describing the way of negotiation with donors. I am noticing the need of a fund raising team creation and also rules of fundraising including necessary cooperation between the center of organization and its local branches.
