31	The Perception of Lexical Similarities Between L2 English and L3 Swedish Utgof, Darja January 2008 (has links) <p>The present study investigates lexical similarity perceptions by students of Swedish as a foreign language (L3) with a good yet non-native proficiency in English (L2). The general theoretical framework is provided by studies in transfer of learning and its specific instance, transfer in language acquisition.</p><p>It is accepted as true that all previous linguistic knowledge is facilitative in developing proficiency in a new language. However, a frequently reported phenomenon is that students see similarities between two systems in a different way than linguists and theoreticians of education do. As a consequence, the full facilitative potential of transfer remains unused.</p><p>The present research seeks to shed light on the similarity perceptions with the focus on the comprehension of a written text. In order to elucidate students’ views, a form involving similarity judgements and multiple choice questions for formally similar items has been designed, drawing on real language use as provided by corpora. 123 forms have been distributed in 6 groups of international students, 4 of them studying Swedish at Level I and 2 studying at Level II. </p><p>The test items in the form vary in the degree of formal, semantic and functional similarity from very close cognates, to similar words belonging to different word classes, to items exhibiting category membership and/or being in subordinate/superordinate relation to each other, to deceptive cognates. The author proposes expected similarity ratings and compares them to the results obtained. The objective measure of formal similarity is provided by a string matching algorithm, Levenshtein distance.</p><p>The similarity judgements point at the fact that intermediate similarity values can be considered problematic. Similarity ratings between somewhat similar items are usually lower than could be expected. Besides, difference in grammatical meaning lowers similarity values significantly even if lexical meaning nearly coincides. Thus, the obtained results indicate that in order to utilize similarities to facilitate language learning, more attention should be paid to underlying similarities.</p> master master's programme language culture general linguistics linguistics foreign language acquisition similarity formal similarity semantic similarity functional similarity transfer transfer of learning language acquisition form form-based research crosslinguistic infuence one-year master english swedish lexical similarities false friends cognates deceptive cognates origin words of the same origin proto-germanic proto-indo-european competence performance comprehension corpus corpus-based data corpus-based research levenshtein distance objective similarity perceived similarity frequency prototype prototypicality proficiency context informed guess simchecker word recognition tachitoscopic experiments semantic correspondence similarity judgements eurocom surface transfer deep transfer lateral transfer English language Engelska språket Linguistic subjects Lingvistikämnen

33	Databáze akustických nahrávek / Database of acoustic records Terz, Marek January 2008 (has links) The databsae of accoustical recordings is a web-based application, which is accessible with an usual web browser. There were used technologies, that are ussually used in web applications. This ensures, that the application is open for using by wide range of users. The application enables uploading WAWE files to the server and allows the user to add various description of the recordings. The application allows also comparing the quality of recordings, which were processed with some method for highlighting the accoustical signal from noise. This function is established by listening tests, which are open for every user, who wants to join the tests.
34	Hardwarová akcelerace algoritmu pro hledání podobnosti dvou DNA řetězců / Hardware Acceleration of Algorithms for Approximate String Matching Nosek, Ondřej January 2007 (has links) Methods for aproximate string matching of various sequences used in bioinformatics are crucial part of development in this branch. Tasks are of very large time complexity and therefore we want create a hardware platform for acceleration of these computations. Goal of this work is to design a generalized architecture based on FPGA technology, which can work with various types of sequences. Designed acceleration card will use especially dynamic algorithms like Needleman-Wunsch and Smith-Waterman.
