Cette thèse s’intéresse au développement phonologique et lexical précoce d’enfants arabophones d’origine tunisienne. Son objectif est de considérer à la fois l’influence des contraintes articulatoires (maturité phonatoire) et les caractéristiques de l’input (LAE : langage adressé à l’enfant) dans les premières productions lexicales. Le corpus de cette étude longitudinale est constitué de productions spontanées de 8 enfants arabophones qui on été enregistrés à leur domicile en situation de communication naturelle avec leurs mères entre 11 et 24 mois. L’analyse des données collectées s’effectue en deux parties. Dans un premier temps, nous mesurons l’influence des contraintes articulatoires (biomécaniques) en examinant l’évolution de la complexité phonétique des premiers mots en utilisant l’Indice de Complexité Phonétique (ICP) de Jakielski (2000). Dans un second temps, nous tentons d’évaluer les effets de l’input maternel par la fréquence d’occurrence des sons présents dans le LAE. Les effets de ces deux facteurs sont observés en fonction des différents stades de développement. Les résultats découlant de notre analyse montrent que la complexité phonétique des productions enfantines augmente avec l’âge et la taille du vocabulaire. Au cours du développement les enfants produisent des mots de plus en plus complexes mais dont la complexité est toujours inférieure à celle des mots visés (cibles). Les premières réalisations enfantines procèdent ainsi d’une forme de « sélection lexicale » que les enfants semblent opérer en fonction de leur maturité phonatoire. Nous avons observé également que la valeur de la complexité phonétique des mots cibles (LAE) est inférieure à celle des mots adultes, ce qui semble témoigner d’une adaptation des mères aux capacités de l’enfant en produisant des mots dont la forme sonore est simplifiée. Par ailleurs, les inventaires phonétiques établis révèlent que l’acquisition du système consonantique est guidée aussi par l’influence de la fréquence des consonnes présentes dans le LAE. Les consonnes bilabiales, approximantes et nasales ont été acquises plus tôt en raison de leur plus haute fréquence dans le LAE. Les formes des mots produits par les enfants tunisiens semblent être influencées aussi par la langue ambiante (arabe tunisien). Avec l’âge, les enfants tunisiens produisent des mots de plus en plus longs (3 syllabes et plus) composés de différentes syllabes de plus en plus complexes (CVCC, CCVC). Enfin nous avons pu décrire, à travers l’analyse des données collectées, le développement des premières productions lexicales en arabe tunisien qui semblent avoir été plus influencées par la complexité phonético-phonologique que par la fréquence d’occurrence. / This Work focuses on early phonological and lexical development of Tunisian Arabic--speaking children. Its aim is to consider both the influence of articulatory constraints (phonatory maturity) and the input characteristics (CDS: Children Directed Speech) on first lexical productions. The data of this longitudinal study consists of spontaneous productions of 8 Arabic-speaking children who have been recorded at home in natural communication environnement with their mothers between 11 and 24 months. Analysis of data executes in two parts. In a first time, we measure the influence of articulatory constraints (biomécanics) by examining the evolution of phonetic complexity of the first words by using the Index of Phonetic Complexity (IPC) (Jakielski 2000). Secondly, we attempt to evaluate the effects of maternal input by the frequency of occurrence of the sounds presents in the CDS. The effects of these two factors are observed according to the linguistic stages of children. Our results show that the IPC children's increases significantly with vocabulary size. Moreover, we showed that although children’s IPC increases with time, its value is always inferior to that of target words. We propose that children’s realizations are the result of some kind of lexical selectivity which is determined by their phonatory maturity. (i.e. words composed of already attested segments in their phonetic inventory). In addition our results reveal that mothers adapt their language to their children’s abilities (i.e. the value of IPC of target words is inferior to that of adult’s words. Otherwise, the phonetic inventory show that the acquisition of the consonant system is also guided by the influence of the frequency of these consonants presents in the CDS. Bilabial consonants, approximants and nasals were acquired earlier because of their higher frequency in the CDS. The shapes of words produced by Tunisian children seem to be influenced also by the ambient language (Tunisian Arabic). With age, Tunisian children produce words increasingly long (three syllables or more) composed of different syllables increasingly complex (CVCC, CVCC). Finally we describe, through analysis of data, the development of the Tunisian first lexical productions that seem to have been more influenced by the phonetic-phonological complexity than by frequency of occurrence.

Acquérir l’adjectif épithète pose deux problèmes majeurs en français. D’abord, l’adjectif dénote une propriété à propos d’un nom, les enfants doivent donc pouvoir concevoir un objet comme un tout et comme un ensemble de propriétés pour manier un SN avec épithète. Ensuite, l’alternance est un trait définitoire de l’adjectif du français, mais son placement n’est pas aléatoire et les contraintes en jeu sont multiples et d’ordre tendanciel. De plus, bien que les locuteurs connaissent cette possibilité, ils optent plutôt pour un placement fixe en usage. Ces faits nous ont amenée à nous demander si l’input permet à l’enfant de se construire la notion d’adjectif épithète sans avoir recours à des connaissances langagières innées. Pour y répondre, nous proposons une étude comparant les usages de trois enfants à ceux de leur famille à deux temps de leur acquisition (T1 : 3 ;8, T2 : 4 ;6). Nous étudions quatre aspects de l’usage de l’épithète (lexique, placement, combinaison avec d’autres modifieurs ou un dépendant adjectival) et nous confrontons l’adjectif aux autres modifieurs nominaux. Ces phénomènes montrent tous la même évolution. À T1, les enfants emploient la construction la plus fréquente des adultes, avec un fort degré de spécificité lexicale. À T2, d’autres constructions émergent selon leur ordre de fréquence chez les adultes. Le lexique de la construction de T1 s’est en outre élargi dans le champ de la classe sémantique des usages de T1. Les enfants montrent ainsi une sensibilité aux informations quantitatives et une abstraction graduelle des structures par analogie sémantique, qui plaident pour une construction progressive de la notion d’adjectif épithète à partir de l’input. / The acquisition of attributive adjectives is subject to two major difficulties in French. First, adjectives express a property of a larger unit : children must be able to conceive an object as a whole and as a set of properties to use a NP with an adjective. Second, adjectives in French may occur before or after the noun. Alternation is a defining feature of the category but it is not random, and the constraints at play are numerous and preferential in nature. Also, although speakers are aware of this possibility, they tend to choose a fixed position in usage. These facts raise the question of whether the input allows children to construct the notion of attributive adjectives without a resort to innate linguistic knowledge. To answer this, I propose a comparative study of the productions of three children interacting with their family at two times of their development (T1 : 3 ;8, T2 : 4 ;6). I examine four phenomena concerning attributive adjectives (lexicon, placement, combination with other modifiers or adjectival dependents), and I compare adjectives with other nominal modifiers. All of these phenomena show the same evolution. At T1, the children use the most frequent construction in the adult data, with a high degree of lexical specificity. T2 shows the appearance of other constructions according to their order of frequency in the adult data. The construction from T1 is also used with a greater choice of lexical units, but within the same semantic classes. The children thus show sensitivity to quantitative information and a gradual abstraction of constructions by semantic analogy, which pleads for a progressive construction of the knowledge of adjectives based on the input data.

The main target of the thesis is analysing of short-term indirect cross-sectoral impacts of taxation of electricity, solid fuels and natural gas on particular sectors of NACE in the Czech Republic, especially impacts on production prices. The key instrument for the analysis is the short-term price model for the Czech Republic, created as a component of the thesis. A secondary target is focused on the analysis of direct impacts, especially impacts on prices and expenditures of particular sectors of NACE. Within the scope of the main target, there are five different variants of taxation. For each of them the impact of taxation of particular commodities on changes in production prices of particular sectors of NACE is simulated. Than two different variants, both of them including taxation of all commodities, are compared. The thesis includes also two hypotheses, which are going to be confirmed or disproved on the basis of obtained results. For achieving the main target the methodology of Leontief input -- output analysis was chosen (Leontief, 1966). This is the key instrument for creating short-term price model for the Czech Republic. This method is suitable especially for analysing short-term cross-sectoral impacts, however under necessary condition of no changes in current technologies, agreements and cross-sectoral relations. This condition represents strict limitation for the price model created for the thesis. Regarding scientific contribution, the main asset of this thesis is creation of macroeconomic short-term price model for the Czech Republic, which is based on methodology of Leontief input -- output analysis. The additional contribution is calculation of the short-term impacts of new environmental taxation on production prices of particular sectors of NACE. Considering available information, environmental taxes in the Czech Republic have not been analysed by Leontief input - output methodology yet. There is not also sufficient analysis of environmental taxes impacts on particular sectors of NACE in the Czech Republic. The thesis is divided to seven chapters. The first chapter focuses on introduction to environmental tax regulation issue. The second chapter presents theories and concepts of taxation impact analysis. The third chapter focuses on models and empirical research in environmental taxation area. The fourth chapter is dealing with basic practical aspects of introduction of new energy taxation in the Czech republic and presents data useful for the following analysis. The fifth chapter consists of describing of applied methodology and describing of creation of the price model. The sixth chapter summarises results of simulation of direct impact of taxation on average prices for companies and on expenditures of particular sectors of NACE. The seventh chapter presents results of cross-sectoral analysis of indirect macroeconomic impacts for all variants; the chapter includes also testing of hypotheses and comments of final results.

AC/DC Buck converters have been used widely in many applications from cell phones to vehicle battery chargers. Due to their importance many researchers have been studying their behavior to improve their efficiency and reduce their size and/or cost. One of the most common defects of these converters, whether they are used for high power or low power applications, is the unwanted ripples in the input voltage across the input stage. It is believed that these ripples are caused by the interaction between the converter itself or its controller with the rectifier required to change the AC input into DC followed by an input filter. Many strategies have been suggested to tackle this problem. A new strategy to improve the controller of that converter was suggested by M. Lenells [1] and it was based on a Hamiltonian model for the 3-phase AC/DC converter together with its rectifier. As a first step, we simulated this model for a single-phase DC/DC buck converter only using the so-called S-Functions in MATLAB/SIMULINK. Then we could find a control law that would reduce the ripples in the input voltage and keep the output voltage constant simultaneously. In this report, we present this model and its simulation to pave the way for the control and simulation of the 3-phase AC/DC converter.

The primary purpose of this dissertation is to analyze the supply and demand of energy in China by utilizing an input-output-analysis. The energy input-output table used in this dissertation was combined with other data from the Energy Statistics Yearbook of China to draw up a hybrid-unit input-output table diagram and its simulation analysis. According to the data, the shortage in China¡¦s electric-producing sector in 1997 had the strongest impact on the total output of China¡¦s economy. Over the years, electric producers have been gradually playing a vital role as China¡¦s main energy source. The analysis also pointed out that China¡¦s energy industry was insignificant prior to 1997, mainly due to government price regulation. This dissertation is therefore expected to identify a new path in the study of energy demand and supply in China.

This thesis is a resource document for computer information that is not presently available as a single unit. It describes most of the commonly available computer peripherals and some not-so-common ones from the micro, mini, and mainframe computer worlds. Physical descriptions, methods of operation, trouble shooting, maintenance, and some schematics and future trends are covered. A few older devices having historical significance are also discussed.By knowing where the computer industry is currently and seeing where it has been hardware-wise, it should be possible to project the direction in which the computer industry is headed. People in the computer profession and people that use computers need to be educated about peripheral devices so that they may make informed decisions on which equipment to acquire and in planning for the future. This thesis should be a valuable aid in this process. The information presented should save time and money during the decision-making process and lead to more effective choices of equipment. / Department of Computer Science

We present an approach to designing input devices that focuses on the structure of materials. We explore and visualize how a material reacts under manipulation, and harness the material’s properties to design new movement sensors. Two benefits spring out of this approach. One, simpler sensing emerges from making use of existing structure in the material. Two, by working with the natural structure of the material, we create input devices with readily recognizable affordances. We present six projects using this approach. We use the natural structure (coordination) of the human body to enable a mapping from five clothing-mounted accelerometers to high-quality motion capture data, creating a low-cost performance animation system. We design silicone input devices with embedded texture allowing single-camera tracking. We study squishable, conformable materials such as foam and silicone, and create a vocabulary of unit structures (shaped cuts in the material) for harnessing patterns of compression/tension to capture particular manipulations. We use this vocabulary to build soft sensing skeletons for stuffed animals, making foam cores with e-textile versions of our unit structures. We also use this vocabulary to design a tongue input device for a collaboration with Disney Imagineering. Finally, we rethink this vocabulary and apply it to capturing, using air pressure sensors, manipulations of hollow 3D-printed rubber shapes, and 3D-print several interactive robots incorporating the new vocabulary.

The aim of the thesis is to present the process connected with the identification of industrial clusters and to point out possible methods and instruments that are useable by such identification. The target is not only focussed on description of these methods but also on consideration that the methods are likewise useful in regions of Czech Republic, especially taken into account the existing offer of regional data. The diplom thesis consists of three parts. The first part represents theoretical introduction to clusters' problem. The second part, also the theoretical one, deals widely with quantitative and qualitative methods and with procedures and clasification that belong to these methods. The third part applies the theoretical knowledge into practices. The comparison methods are used in the theoretical part and the methods of analysis, synthesis, comparison and induction are used in the practical part. The diplom thesis brings a quantitative extension of methods that have been used so far when identifying the industrial clusters in Czech Republic. Due to the present trend of prefering the qualitative methods, the extension of quantitative methods could be seen as a retrograde act. But the conditions of Czech Republic tourned out that, in fact, it is a suitable extension of statistical instruments.

This diploma thesis discusses utilization of dynamic Input-Output models as a basis for decision-making for policy makers. The first part is focused on theoretical derivation of the basic dynamic models. This part is followed by a practical application of the presented models, which proposes a method of deriving the matrix of capital and it facilitates the construction of data sources. The results show that the dynamic models are usable, but it is necessary to take into consideration their structural constraints and data limits. Data applied for 2009 show that the economic crisis has led to a 6% decline in GVA growth rates.
