The performance of a home-built tunable diode laser (TDL) spectrometer has been optimized regarding multi-line detection of carbon dioxide in natural gases. In the regime of the (30<SUP>0</SUP>1)<SUB>III</SUB> ← (000) band of <SUP>12</SUP>CO<SUB>2</SUB> around 1.6 μm, the dominating isotope species <SUP>12</SUP>CO<SUB>2</SUB>, <SUP>13</SUP>CO<SUB>2</SUB>, and <SUP>12</SUP>C<SUP>18</SUP>O<SUP>16</SUP>O were detected simultaneously. In contrast to most established techniques, selective measurements are performed without any sample preparation. This is possible since the CO<SUB>2</SUB> detection is free of interference from water, ubiquitous in natural gases. Detection limits in the range of a few ppmv were obtained for each species utilizing wavelength modulation (WM) spectroscopy with balanced detection in a long-path absorption cell set-up. Linear calibration plots cover a dynamic range of four orders of magnitude, allowing for quantitative CO<SUB>2</SUB> detection in various samples, like soil and breath gas. High isotopic resolution enables the excellent selectivity, sensitivity, and stability of the chosen analytical concept. The obtained isotopic resolution of typically ± 1.0 ‰ and ± 1.5 ‰ (for 3 vol. % and 0.7 vol. % of CO<SUB>2</SUB>, respectively) offers a promising analytical tool for isotope-ratio determination of carbon dioxide in soil gas. Preliminary experiments on soil respiration for the first time combine the on-line quantification of the overall carbon dioxide content with an optode sensor and isotopic determination (TDL system) of natural gas species.

Le présent projet vise à mieux comprendre les difficultés reliées à l’acquisition de la coréférence chez les enfants francophones présentant un trouble développemental du langage (TDL) et à déterminer les différents facteurs influençant son acquisition et sa maitrise. La définition actuelle du TDL indique qu’il s’agit d’une difficulté du langage oral qui affecte à la fois la compréhension et l’expression. Il s’agit d’un trouble neurodéveloppemental caractérisé par des retards développementaux très variables dans une ou plusieurs sphères langagières. Deux théories sont vues en détail : la théorie de la complexité des structures syntaxiques (van der Lely et Stollwerck, 1997) et la théorie du déficit de la mémoire de travail (Montgomery et Evans, 2009). La première propose que les difficultés d’utilisation de la coréférence soient dues à la représentation innée de la syntaxe qui serait immature pour les enfants TDL et, en particulier, le principe B qui ne serait pas acquis. En revanche, Montgomery et Evans soutiennent que cette difficulté de compréhension et d’utilisation provient d’une limitation quant à la mémoire de travail plus précisément avec l’allocation et la capacité des ressources attentionnelles. Nous concluons que les différents facteurs influençant l’acquisition de la coréférence chez les enfants ayant un TDL sont les suivants : premièrement, l’enfant doit posséder les connaissances lexicales et sémantiques reliées aux pronoms et aux anaphores ; deuxièmement, l’enfant doit acquérir des connaissances syntaxiques afin de connaitre les antécédents possibles pour les pronoms et les anaphores ainsi que les règles les reliant. Finalement, la mémoire de travail et l’allocation et la capacité des ressources mentales jouent un rôle important dans la résolution des anaphores. Il est donc clair, selon nous, que les théories ne sont pas totalement suffisantes pour expliquer les troubles de la coréférence, mais qu’elles permettent d’expliquer en partie d’autres types de problèmes qui sont nécessaires pour la résolution de l’anaphore. La résolution des anaphores est un phénomène important surtout chez les enfants francophones puisqu’il s’agirait d’un marqueur clinique du trouble en français. / This project aims to understand the difficulties related to the acquisition of coreference of French speaking children with developmental language disorder (DLD) and to determine the various factors influencing its acquisition and mastery. The current definition of DLD indicates that it is a spoken language difficulty that affects both comprehension and expression. It is a neurodevelopmental disorder characterized by highly variable developmental delays in one or more language spheres. Two theories are seen in detail: the computational grammatical complexity (CGC) hypothesis (van der Lely and Stollwerck, 1997) and the working memory–based account (Montgomery and Evans, 2009). The CGC theory proposes that the difficulties of using coreference are due to the innate representation of the syntax which would be immature for DLD children and particularly the principle B which would not be acquired. In contrast, Montgomery and Evans argue that this difficulty in understanding and using anaphoras stems from a limitation in working memory and specifically with the allocation and capacity of attentional resources. Different factors influencing the acquisition of coreference in children with are discussed. First, the child must have lexical and semantic knowledge related to pronouns and anaphoras. Second, the child must acquire syntactic knowledge in order to know the possible antecedents for pronouns and anaphoras as well as the rules connecting them. Finally, working memory and the allocation and capacity of mental resources play an important role in the resolution of anaphoras. It is thus clear, according to us, that the theories are not totally sufficient to explain the deficit in coreference, but they partly explain other types of problems which are necessary for the resolution of the anaphora. The resolution of anaphoras is an important phenomenon for a good understanding of developmental language disorder, especially in French speaking children, since it is a clinical marker of the disorder in French.

ITC/USA 2009 Conference Proceedings / The Forty-Fifth Annual International Telemetering Conference and Technical Exhibition / October 26-29, 2009 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The integrated Network-Enhanced Telemetry (iNET) project conducted an assessment to determine how the Test and Training Enabling Architecture (TENA) would integrate into an iNET Telemetry Network System (TmNS), particularly across constrained environments on a resource constrained platform. Some of the key elements investigated were quality of service measures (throughput, latency, and reliability) in the face of projected characteristics of iNET Data Acquisition Unit (DAU) devices including size, weight, and power (SWAP), and processing capacity such as memory size and processor speed. This paper includes recommendations for both the iNET and TENA projects.

The dissertation is divided into three chapters, the first presents historical elements of the Archdiocese of Goiânia, starting with the presence of the first colonizers who reached the region. In the second chapter, the theoretical references are presented: biblical and theological foundations and a sociological overview, using classics of sociology of religion, especially works of Otto Maduro. In the third chapter I try to define in detail why certain specific pastoral acts of Dom Antonio can be considered prophetical, using the references exposed in the previous chapter. Finally, in the conclusion I try to prove the hypothesis presented in the beginning. Considering the historical, social and eclesial circumstance of the Archdiocese, which influenced Dom Antonio in his pastoral activity it is possible to affirm that his action can be characterized as prophetic, using the referentials adopted. Those acts also influenced the historical, social and eclesial formation of the society in which he lived and worked as Archbishop. / Neste trabalho de pesquisa, buscou-se analisar as ações proféticas de Dom Antonio Ribeiro de Oliveira, enquanto arcebispo metropolitano da Arquidiocese de Goiânia. Dividida em três capítulos, a dissertação traz, no primeiro, elementos históricos dessa Arquidiocese, partindo da presença dos primeiros colonizadores que foram ocupando a região. No segundo, o referencial teórico: as mediações bíblico-teológicas e a ótica sociológica, valendo-se de clássicos da sociologia da religião e, particularmente, de Otto Maduro. No terceiro capítulo buscou-se definir, com detalhes, determinadas ações pastorais de Dom Antonio, e por que estas podem ser consideradas proféticas, valendo-se do referencial trabalhado do capítulo anterior. Por fim, na conclusão procurouse comprovar a hipótese apresentada inicialmente. E considerando as circunstâncias histórico-social e eclesial da Arquidiocese que influenciaram Dom Antonio em suas atividades pastorais e a partir do referencial adotado, pode-se afirmar que ações suas caracterizam-se como proféticas. Como tais, essas ações influenciaram também na formação histórico-social e eclesial da sociedade em que viveu e atuou como Arcebispo.

This thesis investigates the use of field-programmable gate arrays (FPGAs) to implement a time-to-digital converter (TDC) with on-chip calibration and temperature correction.Using carry-chains on the Xilinx Kintex UltraScale architecture to create a tapped delay line (TDL) has previously been proven to give good time resolution.This project improves the resolution further by using a bit-counter to handle bubbles in the TDL without removing any taps.The bit counter also adds the possibility of using a wave-union approach previously dismissed as unusable on this architecture.The final implementation achieves an RMS resolution of 1.8 ps.
