The Italian gerund and its Czech equivalents: a parallel-corpus based study
Jarkovská, Jana ; Štichauer, Pavel (advisor) ; Špaček, Jiří (referee)
The Italian gerund and its Czech equivalents: a parallel-corpus based study The Italian gerund is a frequent indefinite verbal form. It's usually used in different verbal constructions or in implicit phrases. In those it can have various functions. We can classify gerundio modale, strumentale, temporale, causale, ipotetico, concessivo and gerundio coordinato. In this study is used a Czech-Italian parallel corpus InterCorp to analyze the gerund closer. It was found out that the most frequent gerunds in italian texts are these: facendo, cercando, guardando, dicendo, parlando, essendo, lasciando, pensando, avendo, passando, seguendo, andando, ridendo, sorridendo, indicando, vedendo, diventando, tenendo, correndo and dando. A sub-corpus, texts by I. Calvino, was chosen in order to compare these most common forms in general with the most frequent gerunds from single texts. The study analyzes particular examples of the gerunds, their functions and their translations into the Czech language in this sub-corpus. The different types of translations are classified according to the classification made by S. Hamplová in her Mluvnice italštiny (Italian Grammar). In accordance with this source the gerund in the sub-corpus is mostly translated by a coordinated or subordinated phrase, a nominal construction or by a...

Parallel data-processing on GPGPU
Vansa, Radim ; Kruliš, Martin (advisor) ; Zavoral, Filip (referee)
Modern graphic cards are no longer limited to 3D image rendering. Frameworks such as OpenCL enable developers to harness the power of many-core architectures for general-purpose data-processing. This thesis is focused on elementary primitives often used in database management systems, particularly on sorting and set intersection. We present several approaches to these problems and evalute results of benchmarked implementations. Our conclusion is that both tasks can be successfully solved using graphic cards with significant speedup compared to the traditional applications computing solely on multicore CPU.

Algorithms for Parallel Searching in XML Datasets
Kruliš, Martin
This thesis will address the problems of indexing XML datasets and finding effective searching methods for indexed data. Defining data structures and algorithms that take highly parallel approach to the searching problem is considered to be main objective, therefore the implementation may benefit from the power of multicore CPUs. Prototype of such implementation will be presented with the thesis. Internal query model will be developed as a common layer. Multiple front-ends representing different query languages will be able to operate on the top of this model, thus the engine will not be dependent on any particular language. Sample front-end for a subset of XPath will be implemented along with the prototype.

The Parallel Genetic Algorithm for Multicore Systems
Vrábel, Lukáš ; Šimek, Václav (referee) ; Jaroš, Jiří (advisor)
Genetický algoritmus je optimalizačná metóda zameraná na efektívne hľadanie riešení rozličných problémov. Je založená na princípe evolúcie a prirodzeného výberu najschopnejších jedincov v prírode. Keďže je táto metóda výpočtovo náročná, bolo vymyslených veľa spôsobov na jej paralelizáciu. Avšak väčšina týchto metód je z historických dôvodov založená na superpočítačoch alebo rozsiahlych počítačových systémoch. Moderný vývoj v oblasti informačných technológií prináša na trh osobných počítačov stále lacnejšie a výkonnejšie viacjadrové systémy. Táto práca sa zaoberá návrhom nových metód paralelizácie genetického algoritmu, ktoré sa snažia naplno využiť možnosti práve týchto počítačových systémov. Tieto metódy sú následne naimplementované v programovacom jazyku C za využitia knižnice OpenMP určenej na paralelizáciu. Implementácia je následne použitá na experimentálne ohodnotenie rozličných charakteristík každej z prezentovaných metód (zrýchlenie oproti sekvenčnej verzii, závislosť konvergencie výsledných hodnôt od miery paralelizácie alebo od vyťaženia procesoru, ...). V poslednej časti práce sú prezentované porovnania nameraných hodnôt a závery vyplývajúce z týchto meraní. Následne sú prediskutované možné vylepšenia daných metód vyplývajúce z týchto záverov, ako aj možnosti spracovania väčšieho množstva charakteristík na presnejšie ohodnotenie efektivity paralelizácie genetických algoritmov.

Parallel Corpus Manager
Kouřil, Jan ; Dytrych, Jaroslav (referee) ; Smrž, Pavel (advisor)
The goal of diploma project was to implement parallel corpus manager, which can align parallel texts in different languages and insert them into corpus, where several more processing functions are provided. Program provides possibilities of automatic text alignment and its interactive editing. These aligned texts are then inserted into corpus. Program can work with multiple corpora, parallel corpus is allways identified by a couple of languages. In corpus, there are possibilities to search by many categories, view and edit particular selections, lemmatize and morphologically tag given texts, sort selections, import and export data, in many ways edit corpus for further easy navigation and add new expressions to managed dictionaries. Particular chapters describe introduction to corpus problematics, theory of aligning parallel texts, morphological text tagging and lemmatization, external tools used in program, most common subtitle formats and implementation solution of particular problems.

Secondary electron contrast of doped regions in semiconductor
Čižmár, Petr
The aim of the dissertation is study of multi-channel spectroscopy of electrons (secondary, both elastically and non-ellastically reflected as well as the Auger ones) in a scanning electron microscope with respect to the signal-to-noise ratio in detected signals. Another aim is to write software for electronic processing of an image of a specimen providing combined analytical and microscopic information. Verification of the methodology at an ultra-high vacuum microscope with slow electrons, which will be equipped with a parallel hyperbolic electrons analyzer in the scope of the project, is one of main goals of the experimental part.
