Previous researchers have concluded that there is a need for determining how vocabulary instruction effects vocabulary comprehension and reading comprehension for young learners. Researchers have implemented morphemic strategies in various studies to identify effective methods for vocabulary instruction. In the present study, four prefixes were taught to students with disabilities to extend vocabulary research by using a morphological approach with a focus on prefix instruction. In addition students were taught how to combine the meaning of a prefix to the meaning of a root word. Data patterns indicate an increase in students' ability to provide definitions for prefixed words while the transfer to reading comprehension was minimal. The results of this study provide direction for future research in implementing a morphemic approach for vocabulary instruction.

<p>In the field of Tracking and Data Fusion most, if not all, computations executed by a computer are carried out serially. The sole part of the process that is not entirely serial is the collection of data from multiple sensors, which can be executed in parallel. However, once the data is to be filtered the most likely candidate is a serial algorithm. This is due in large part to the algorithms themselves that have been developed over the last several decades for use on conventional computers that have been left void of parallel computing capabilities, until now. With the arrival of graphical processing units, or GPUs, the tracking community is in a favourable position to exploit the functionality of parallel processing in order to track a growing number of targets. The problem, however, begins with the sheer labour of having to convert all the pre-existing serial tracking algorithms into parallel ones. This is clearly a daunting task when one considers the extent to which the tracking community has gone to develop modern day filters such as Alpha Beta filters, Probabilistic Data Association filters, Interacting Multiple Model filters, and several dozen, if not hundred, variants of the aforementioned. It is most likely that these filters will find some kind of a parallelization in the near future as ever more sensors are dispersed throughout society and even more targets are monitored with these sensors. The volume of targets then becomes simply too unmanageable for a serial algorithm and more focus is placed iv on parallel ones. Yet, before the parallel algorithms can be utilized they have to be derived. It is the derivation of these parallel algorithms which is the focus of this thesis. However, it should be made clear that it would be impossible to formulate a parallelization for every filter found in the literature, and so the goal here is to direct the attention onto one filter in particular, the Kalman filter.</p> / Master of Applied Science (MASc)

4 TITLE: Teaching aids for work with verbs of movement at elementary level in Russian language teaching SUMMARY: This diploma thesis deals with the topic of Russian verbs of movement. The aim of the thesis is to compile a comprehesive set of practical exercises and additional teaching materials (work sheets), which can be used as a supporting material in Russian language teaching. The set of practical exercises and additional teaching material is suitable for students at the age of thirteen years and above. The thesis is divided into two parts - theoretical and practical. The teoretical part defines verbs of movement from a linguistic aspect and generally characterizes the didactic approaches to teaching foreign language grammar. Practical part includes a comprehensive set of practical exercises and additional teaching materials focused on a presentation and practice of selected verbs of movement. KEY TERMS: verbs of movement with prefix, verbs of movement without prefix, verb aspect, didactic approaches and principles, practical exercises, teaching aid, work sheet

This paper describes a wireless communication model based on IEEE 802.11n. Typical methods for channel equalisation and estimation are described, such as the least squares method and the minimum mean square error method. Equalization based on deep learning was used as well. Coded and uncoded bit error rate was used as a performance identifier. Experiments with topology of the neural network has been performed. Programming languages such as MATLAB and Python were used in this work.

BGP hijacking is a threat to network organizations because traditional BGP protocols were not designed with security in mind. Currently, research to combat hijacking is being done by detecting hijacking in real time from Public Route Collectors. However, by using AS-Path Prepending, a well-known traffic engineering technique, hijackers could adjust the influence scope of hijacks to potentially avoid Public Route Collectors. This thesis investigates fist, whether AS-Path Prepending is sufficient to hide from Public Route Collector, and second whether the hijacker can predict its hijack’s stealthiness by simply comparing the AS path length with the victim. Last, we investigate the non-hijacker-controlled parameters, which are the geographical locations and victim prepending times if the victim also enable AS-Path Prepending for traffic engineering in our study. Our results show that on one hand, AS-Path Prepending benefits stealthy hijacks to route collectors. While on the other hand, it is not sufficient to completely hide from route collectors only using it. By simply comparing the AS paths length, the hijacker’s prediction is constructive but not practical. And non-hijacker-controlled parameters indeed can significantly affect the stealthiness of hijacking. / BGP-kapning är ett hot mot nätverksorganisationer eftersom traditionella BGP-protokoll inte har utformats med säkerheten i åtanke. För närvarande bedrivs forskning för att bekämpa kapning genom att upptäcka kapning i realtid från offentliga ruttinsamlare. Genom att använda AS-Path Prepending, en välkänd trafikteknik, kan kapare dock justera kapningarnas inflytande för att eventuellt undvika offentliga ruttinsamlare. I den här avhandlingen undersöks för det första om AS-Path Prepending är tillräckligt för att dölja sig för Public Route Collector och för det andra om kaparen kan förutsäga hur smygande kapningen är genom att helt enkelt jämföra AS Path-längden med offrets. Slutligen undersöker vi de parametrar som inte kontrolleras av kaparen, dvs. geografiska platser och offrets prependingtider om offret också aktiverar AS-Path Prepending för trafikteknik i vår studie. Våra resultat visar att AS-Path Prepending å ena sidan gynnar smygande kapningar av ruttinsamlare. Å andra sidan räcker det inte för att helt och hållet dölja sig för ruttinsamlare om man bara använder det. Genom att helt enkelt jämföra AS-vägarnas längd är kaparens förutsägelser konstruktiva men inte praktiska. Parametrar som inte kontrolleras av kaparen kan faktiskt påverka kapningens smygande på ett betydande sätt.

In this study an attempt is made to describe the morphological apects of Tshiguvhu. In chapter 1, it is indicated that historically, there was extensive early contact between Vhaguvhu and Balobedu and Tlokwa. In ,chapters 2 and 3, nouns and pronouns are analysed morphologically. Some similarities and differences between Tshiguvhu and Tshivenda are highlighted. These differences are ascribed to influences from Lobedu and Tlokwa. In chapters 4 and 5, the form of the verb and the use of verb forms in various tenses, where applicable, are described morphologically. Some verb roots and extensions have been influenced by Northern Sotho dialects whereas some have not. In chapter 6, the morphology of adverbs, interrogatives, conjunctions, ideophones and interjections are briefly described. In conclusion, it is indicated that Tshiguvhu is a dialect of Venda because of its cultural and historical bonds with Venda, although linguistically it shares some features with certain Northern Sotho dialects. / African Languages / M.A. (African Languages)

Ce travail étudie les déviations de sommes ergodiques pour des systèmes dynamiques substitutifs avec une matrice qui admet des valeurs propres de module supérieur à 1. Précisément, nous nous concentrons sur les substitutions telle que ces valeurs propres ne sont pas conjuguées. Dans un premier temps, on défini les lettres a-minimales et dominantes d'un mot pour étudier sa ligne brisée associé. On défini la ligne brisée normalisée et sa fonction limite. Pour l'étude des sommes ergodiques, on défini le sous-automate des lettres minimales. On donne des conditions sur une substitution de sorte qu'il y ait un nombre infini des sommes ergodiques égales à zéro pour un point x 2 X. Enfin, en utilisant un boucle dans une classe de Rauzy, on prouve l'existence d'un nombre infini d'échanges d'intervalles auto-similaires, dont la matrice de Rauzy a deux valeurs propres non conjuguées de module supérieur à 1. Et tout échange d'intervalles affine semi-conjugué à cet échange d'intervalles est aussi conjugué. / This thesis focuses on the deviation of ergodic sums for a substitution dynamical systems with a matrix that admits eigenvalues of modulus larger than 1. Specifically, we concentrate on substitutions with non-conjugated eigenvalues. At first, we define the a-minimals letters and the dominant letters of a word to study its broken associated line. We define the normalize broken line and its limit function. For the study of ergodic sums, we define the sub-automaton of minimum letters. We give conditions on a substitution so that there is infinitely many zero sums ergodic for a point x 2 X. Finally, using a loop in a class of Rauzy, we prove the existence of infinitely many interval exchange transformation self-similar, whose Rauzy matrix has two non-conjugated eigenvalues larger than 1 and every affine interval exchange transformation that is semi-conjugated, is also conjugated.

O prefixo ver- já foi tema de estudo para diversos linguistas que se dedicam à língua alemã (LEOPOLD, 1907; SCHIRMEIER, 2006, entre outros). O caráter polissêmico desse prefixo é o grande motivo para tamanho interesse. Diferentemente dos trabalhos citados, esta dissertação analisa novas formações verbais com o prefixo ver-, a fim de descobrir regularidades, tanto semântica quanto morfológicas no processo de formação dos verbos. Para tanto, pesquisamos novos verbos ainda não lexicalizados em um sítio eletrônico (http://www.deflok.de/HipHopLyrics/Texte/), composto por letras de música do hip hop alemão. Assim, o endereço virtual foi tomado como corpus para a tarefa. A busca permitiu encontrar doze novos verbos: verbassen, verspeien, verpeilen, verchecken, verächten, verkreuzen, verstumpfen, vergaukeln, verschlendern, vernabeln, verreimen, verstottern. Para tanto, os dicionários DUDEN (www.duden.de), Langescheidt (versão digital) e PONS (versão digital) foram usados como ferramenta de exclusão lexicográfica. O dicionário DUDEN funcionou também como fonte para conhecer as acepções que o prefixo ver- imprimia nos derivados em que se encontrava. O arcabouço teórico usado teve como base os conceitos da teoria da gramática de construções, a partir de GOLDBERG (1995) que permitiram conhecer novas propostas de interpretação dos mecanismos envolvidos na formação dos verbos com o prefixo ver. Ademais, recorremos à teoria da mesclagem de FAUCONNIER & TURNER (2003) para explicar a construção de sentido de determinados verbos, uma vez que essa permitia explorar aspectos não contemplados pela teoria da gramática de construções. / The prefix ver- has already been a theme of many linguistics (LEOPOLD, 1907; SCHIRMEIER, 2006, and others), that are dedicated to German language. The polissemic aspect from this prefix is the main reason for such a big interest. Unlike those authors, with this paper I analyse new verbal formations with the prefix ver- in order to discover semantic as well as morphological regularities in the process of verbal formations. Therefore, I researched new not yet lexicalized verbs in a website (http://www.deflok.de/HipHopLyrics/Texte/), composed of hip hop lyrics in German. The web address was treated as the corpus. Twelve new verbs were detected: verbassen, verspeien, verpeilen, verchecken, verächten, verkreuzen, verstumpfen, vergaukeln, verschlendern, vernabeln, verreimen, verstottern. In order to verify that these verbs were not yet lexicalized we used the following dictionaries: DUDEN (www.duden.de) and the digital version of Langenscheidt, and PONS. The dictionary DUDEN also served to specify the different meaning, that the prefix ver- gives to the derivates, in which it is part of. The theoretical support is based on the terms and definitions of the construction grammar (Goldberg, 1995), that allowed to get a new point of view about the mechanisms involved in the verb formation with the prefix ver-. Complementary I employed the definitions proposed by FAUCONNIER & TURNER (2003) to explain the meaning of certain neologism to which the construction grammar theory could not be applied.
