This project describes the implementation of an LZ4 compression algorithm in a C/C++-like language, that can be used to generate VHDL programs for FPGA integrated circuits embedded in accelerated network interface controllers (NICs). Based on the algorithm specification, software versions of LZ4 compressor and decompressor are implemented, which are then transformed into a synthesizable language, that is then used to generate fully functional VHDL code for both components. Execution time and compression ratio of all implementations are then compared. The project also serves as a demonstration of usability and influence of high-level synthesis and high-level approach to design and implementation of hardware applications known from common programming languages.

This master thesis deals with ways to store passwords in current operating systems. Specifically, this work focuses on Windows, Linux, BSD and OS X. These systems are examined for ways of hashing passwords and on resistance of resulting hashes against various attacks. First (theoretical) section describes the procedures and algorithms that are needed for user authentication. This part also describes methods of hash storing. At the end of the theoretical part are generally described some possible attacks against hash functions. In second (practical) part is described and tested tools for obtaining hashes of the investigated operating systems. Subsequently practical attacks were conducted against obtained hashes by using appropriate tools. Furthermore there are presented results of the attacks. In the conclusion of the work there is a comparison of tools and methods which were used to obtain plaintext passwords from operating systems.

Das Projekt \"Altägyptische Wörterbücher im Verbund\" ist ein am Ägyptologischen Institut der Universität Leipzig angesiedeltes Teilvorhaben des Projekts „Wissensrohstoff Text“, an dem sich, aus ESF-Mitteln finanziert, sieben Leipziger geisteswissenschaftliche Institute und das Institut für Informatik beteiligen. Das Ägyptische weist eine mehr als 4000jährige Sprachgeschichte auf. Nach der Entzifferung der Hieroglyphen durch J.-F. Champollion (1822) widmete man sich im 19. und frühen 20. Jh. der Erfassung des Wortschatzes und der Ermittlung von Wortbedeutungen. Das Ende dieser Pionierphase markiert das Wörterbuch der ägyptischen Sprache von Erman/Grapow (Hauptbände 1926-1931), das noch heute ein Standardwerk darstellt. Diesem gehen aber bereits eine Vielzahl von Wörterbüchern, Wortlisten und Glossaren voran, die inzwischen weitgehend vergessen, aber wissenschaftsgeschichtlich von höchster Bedeutung sind. Denn aus ihnen lassen sich einerseits das schrittweise Verständnis der ägyptischen Sprache und die angewandten Methoden zu ihrer Erschließung ablesen und andererseits das Fundament unseres heutigen lexikographischen Wissens eruieren. Das Projekt schafft mittels eines Wörterbuchportals eine Infrastruktur, um das Vorkommen von Wörtern in altägyptischen Wörterbüchern und anderen lexikogra-phisch relevanten Publikationen mit den modernen Lemmaansetzungen der digitalen Wortliste des Thesaurus Linguae Aegyptiae (TLA) (http://aaew.bbaw.de/tla) zu ver¬knüpfen. So wird eine automatisierte Auswertung der Wörterbücher als Beitrag zur Geschichte der ägyptischen Lexikographie ermöglicht. Der TLA enthält neben einer Wortliste eine Textdatenbank, so dass über die Verknüpfung mit der Wortliste auch eine Verlinkung mit ägyptischen Volltexten und Textbelegen erfolgt. This article presents a short overview of the project „Altägyptische Wörterbücher im Verbund“ hosted at Leipzig University. Its aim is to establish a digital infrastructure for linking the lexical material of selected dictionaries of Ancient Egyptian of the 19th and early 20th century to a modern standard wordlist, the one of the Thesaurus Linguae Aegyptiae (TLA).

This year the Institute of the Czech Language AS CR (Ustav pro jazyk cesky AV CR) is celebrating the 100th anniversary of foundation of its direct predecessor, the Office of the Dictionary of the Czech Language (Kancelar Slovniku jazyka ceskeho, KSJC) which provided the administrative background for an ambitious lexicographic project launched already in 1905 by the committee for lexicography and dialectology the Czech Academy of Emperor Franz Joseph for sciences, literature and art, to become the Czech Academy for Sciences and Art (CAVU) in 1918. Although much was done between the wars to establish a state-funded language institute, i.e. an institution which would unify the all-encompassing research of language and systematic work with the national language, for financial reasons the Czech Language Institute was established only in 1946. Six years later, the Czechoslovak Academy of Sciences (CSAV) was founded and incorporated, among others, the Institute of the Czech Language. During the years, the structure of the Institute underwent various changes which were not merely a response to linguistic needs but also to the events of the time relating to the strengthening of the totalitarian communist power. Top Communist Party officials often interfered with personnel matters of the Institute and...

Title: Comparative aspects of Latvian and Czech lexicons: Materials for assembling a Latvian-Czech dictionary Autor: Mgr. Michal Škrabal Department: Institute of the Czech National Corpus Supervisor: prof. PhDr. František Čermák, DrSc. The primary aim of this work is to classify the Latvian lexicon, or better its relevant segment, into individual groups, definable semantically, grammatically, syntagmatically, pragmatically, and so on, and to attempt to find for these classifications an ideal method of lexicographical adaptation and apply it to an emerging Latvian-Czech dictionary (the very first manual of its type). To this end, modern instruments were utilized which, in the recent past, have radically altered the methodology of lexicographical work: on the one hand, the linguistic corpora, which nowadays represent authentic, linguistic usage and, on the other hand, the specialized lexicographic software TshwaneLex, in which a lexical database of Latvian is constructed and from which the dictionary itself will be subsequently constructed. Because of the limited size of the Latvian corpus it was not possible to completely eliminate traditional sources, and the author of the work was forced to consolidate traditional and modern lexicographical methods. His primary source however remained the corpus...

Although spoken dialogue systems have greatly improved, they still cannot handle communications involving unknown topics. One of the problems is, that they experience difficulties when they should pronounce unknown words. We will investigate methods that can improve spoken dialogue systems by correcting the pronunciation of unknown words. This is a crucial step to provide a better user experience, since for example mispronounced proper nouns are highly undesirable. Incorrect pronunciation is caused by imperfect phonetic representation of the word. We aim to detect incorrectly pronounced words, use knowledge about the pronunciation and user's feedback and correct the transcriptions accordingly. Furthermore, the learned phonetic transcriptions can be added to the speech recognition module's vocabulary. Thus extracting correct pronunciations benefits both speech recognition and text-to-speech components of the dialogue systems.

The aim of this lexicographical study is to compare the fashion terminology with an emphasis on the 1920s in two German-Czech dictionaries from the first half of the 20th century: Encyclopaedic German-Czech Dictionary by J. V. Sterzinger (1916-1935) and German-Czech Concise Dictionary by J. Janko/H. Siebenschein (1936-1944). The intention is to trace differences in the structure of a lemma and to trace the reasons for its presence (or absence) in the dictionary. Two hypotheses were established for the research. No. 1: New fashion terminology created under certain cultural-historical conditions is represented only in the younger of the two dictionaries; No. 2: The frequency of fashion terminology is higher in the encyclopaedic dictionary than in the concise dictionary. A quantitative analysis was performed on a sample of 370 fashion terms, refuting hypothesis No. 2. It was found that the representation of fashion terminology is similar in both dictionaries. The quantitative- qualitative analysis of the lemma microstructure of the individual fashion terms confirmed hypothesis No. 1. The analysis revealed that the english fashion terminology typical of the 1920s is more frequent in the younger of the two dictionaries.
