晚近金融環境快速變化，金融商品不斷的開發及付款方式不斷的革新，逐漸改變消費者持有現金作為支付工具的習性，使得傳統上只用所得和利率來解釋貨幣需求函數已不太具解釋能力。因此本文將「金融創新」的影響納入貨幣需求函數。 本文實證的變數選擇方面，採用通貨和信用卡的使用分別代表貨幣需求和金融創新以作為分析的重點。實證方法方面，同時採用一般常用的「聯立方程式」－Johansen Procedure和「單迴歸方程式」－OLS、動態OLS(Saikkonen's OLS及Phillips and Loretan's NLS)及FM-OLS來估計信用卡和通貨的關係，並比較這些方法得出的結果。 實證結果比較，發現使用OLS所估計的係數值及圖型均較採用動態OLS及Johansen為佳。在OLS估計時，發現季節性虛擬變數對於估計有重要的影響。 由於使用OLS估計法，在變數為單根時，無法使用一般統計檢定係數顯著性，因此多加入FM-OLS和OLS實證結果的比較，以達能充分了解各變數對於通貨需求的真實影響。 採用FM-OLS實證結果，得到信用卡卡數cn、利率r和實質所得rgnp對於實質通貨淨額rcur的影響顯著，其估計值分別為-0.0025、-0.22與0.60左右。結果顯示當信用卡使用增加、利率增加與所得減少，均會減少通貨的持有，與理論相符。 在採用FM-OLS實證時，發現匯率ex對於通貨需求rcur的影響不顯著，與以往實證結果不符。推測可能原因為(1)通貨持有動機為交易目的，甚少當做投資的工具；(2)過去實證所選取的貨幣需求量為更廣義的M1A、M1B及M2。 第一章　導論 1 第一節 研究動機 1 第二節 研究方法與目的 4 第三節 研究架構 6 第二章 信用卡發展、意義及影響 7 第一節 信用卡的發展 7 第二節 信用卡的意義 9 第三節 信用卡對經濟的影響 11 第三章 貨幣需求理論與文獻回顧 14 第一節 貨幣需求理論 14 1.Baumol and Tobin存貨理論 14 2.Hafiz Akhand and Ross Milbourne 16 第二節 國外實證文獻 21 第三節 國內實證文獻 26 第四章 研究方法 33 第一節 單根檢定 33 1.ADF Test 33 2.Phillips-Perron Test 35 3.Perron Test 36 第二節 共積理論－Johansen Procedure估計法 39 第三節 動態OLS估計法 43 1.Saikkonen's OLS估計法 43 2.Phillips and Loretan's NLS估計法 44 第四節 Fully Modified OLS(FM-OLS)估計法 45 第五章 實證結果 48 第一節 資料說明與處理 48 第二節 單根檢定 50 第三節 Johansen Procedure估計法 53 第四節 OLS及動態OLS的估計及比較 63 1.OLS估計法 63 2.Saikkonen's OLS估計法 69 3.Phillips and Loretan's NLS估計法 78 4.小結 83 第五節 Johansen 與OLS估計結果比較 85 第六節 FM-OLS實證結果與OLS比較 87 第七節 本章實證結果 93 第六章 結論與建議 94

Μελετάται αριθμητικά η υδροδυναμική κυκλοφορία του Πατραϊκού κόλπου. Σκοπό αποτελεί η κατανόηση της τρισδιάστατης δομής της ροής που προκαλείται υπό διάφορες φυσικές φορτίσεις, δηλαδή τον άνεμο, την παλίρροια και τη στρωμάτωση. Η αριθμητική προσομοίωση γίνεται με τον τρισδιάστατο αριθμητικό κώδικας πεπερασμένων όγκων MIKE 3 FM (HD,TR). Η ανεμογενής κυκλοφορία, κατά τους χειμερινούς μήνες οπότε ο κόλπος σύμφωνα με μετρήσεις είναι ομογενής, παρουσιάζει στοιχεία ροής μεγάλης κλίμακας, με επιρροή από τη δύναμη Coriolis, ανάπτυξη στρώματος Ekman και ισχυρά ρεύματα επιστροφής, λίγα μέτρα κάτω από την ελεύθερη επιφάνεια. Ταυτόχρονα, σε περιοχές όπως η θέση του στενού Ρίου-Αντιρρίου η ροή συμπεριφέρεται περισσότερο ως υδραυλική ροή με ταπείνωση της ελεύθερης επιφάνειας και κατακόρυφο προφίλ ταχύτητας, όμοιο με της τυρβώδους ροής Couette. Στην οριζόντια διεύθυνση, η ροή παρουσιάζει έντονα παράκτια ρεύματα και κλίση της ελεύθερης επιφάνειας. Εκτιμάται ότι ο χρόνος ανανέωσης των υδάτων για τον κόλπο θα κυμαίνεται από ένα μήνα έως μία εβδομάδα, ανάλογα με την ένταση του ανέμου. Φαίνεται ότι στα βαθύτερα στρώματα του Πατραϊκού η ανεμογενής ροή δεν επιδρά σημαντικά στην ανανέωση των υδάτων, τα οποία παραμένουν εγκλωβισμένα και επανακυκλοφορούν μεταξύ των δύο εγκάρσιων ραχών που οριοθετούν την λεκάνη του. Τα παλιρροϊκά ρεύματα, τα οποία είναι σημαντικά στον Πατραϊκό, καθορίζουν την κυκλοφορία των υδάτων στο κύριο σώμα του κόλπου και στο στενό Ρίου-Αντιρρίου, ενώ η ανεμογενής ροή είναι καθοριστική κοντά στις ακτές. Η συνδυασμένη δράση ανέμου και παλίρροιας προκαλεί κυκλωνικούς και αντικυκλωνικούς στροβίλους, πλησίον των βορείων και νοτίων ακτών του Πατραϊκού, η φορά των οποίων υπαγορεύεται αποκλειστικά από τα ισχυρά ανεμογενή παράκτια ρεύματα. Η μελέτη της καλοκαιρινής κυκλοφορίας αναδεικνύει σημαντικές διαφορές, σε σύγκριση με την χειμερινή κυκλοφορία των υδάτων στον Πατραϊκό κόλπο. Τα ανεμογενή ρεύματα είναι αμελητέα από τη ζώνη του θερμοκλινούς και κάτω, για τη μέση ένταση ανέμου, ενώ η ένταση της τύρβης περιορίζεται στο επιλίμνιο. Την καλοκαιρινή περίοδο η δράση νοτιοδυτικού ανέμου συνδέεται με την παρουσία αναβλύσεων στις βορειοδυτικές ακτές του όρμου της Ναυπάκτου και στο μέτωπο της λιμνοθάλασσας του Μεσολογγίου. Αναβλύσεις εντοπίζονται και νοτιοδυτικά του Ρίου, μπροστά από την πόλη των Πατρών, για βορειοανατολικούς ανέμους. Στο στενό Ρίου-Αντιρρίου η δράση του ανέμου, αλλά και η παλίρροια οδηγούν στη γένεση εσωτερικών κυμάτων τα οποία προκαλούν κατακόρυφη κυκλοφορία. Κύριο χαρακτηριστικό της κυκλοφορίας των υδάτων στον Πατραϊκό, την καλοκαιρινή περίοδο, είναι ο ισχυρός κυκλωνικός στρόβιλος που παρατηρείται στο κέντρο του κόλπου αναγκάζοντας τα ύδατα σε περιστροφική κίνηση. Με βάση τις αριθμητικές προσομοιώσεις η ύπαρξη ισχυρού κυκλωνικού στροβίλου συνδέεται αποκλειστικά με την παρουσία βορειοανατολικού ανέμου και συγκεκριμένα στη φάση της πλημμυρίδας. Τέλος, με βάση τις αριθμητικές προσομοιώσεις υπολογίζεται το τρισδιάστατο πεδίο ρευμάτων στην ευρύτερη περιοχή του παλαιού και νέου λιμένα Πατρών, καθώς και η διάχυση και μεταφορά των επεξεργασμένων λυμάτων από τον αγωγό της ΔΕΥΑΠ. / The hydrodynamic circulation in the Gulf of Patras, in Western Greece, is studied using three-dimensional numerical simulations. The simulations are performed using the three-dimensional modeling system MIKE 3 FM (HD/TR). The wind-induced circulation is examined in the natural basin of the Gulf of Patras, in which batotropic flow develops, according to field measurements, during the winter months. The simulations show that the wind-induced flow creates strong currents near the coasts, which determine the sense of rotation of the gyres that develop in the Gulf. Strong currents are also created at the Rio-Antirio straits. The wind-induced, barotropic currents do not seem to contribute to the renewal of bottom waters, which recirculate between the two sills. Depending on the speed of the wind forcing the flow, the residence time of the waters in the Gulf of Patras is estimated to range from one month to one week. The tide-induced circulation is important in the Gulf of Patras. Strong, tidal currents have been simulated to develop at the straits of Rio-Antirrio and in the main body of the Gulf, with cyclonic and anticyclonic eddies developing at the northern and southern coasts, respectively. When there is also wind blowing, nearshore gyres develop, the sense of rotation of which is by the wind direction, while in the central part of the Gulf the flow pattern is dictated by the tidal action. Further, the baroclinic wind and tide-induced circulation are studied to investigate the effect of stratification on the structure of the flow. During the summer period the wind-induced flow and the wind generated turbulence driven by winds of medium strength are restricted to the upper layer of the epilimnion, while the strong winds cause tilt and erosion of the thermocline in the central part of the Gulf and generation of internal waves at the straits of Rio-Antirio. Salient features of the summer circulation are the strong upwellings and the central cyclonic gyre which are predicted using numerical simulations. Upwellings occur along the northwesterly portion of the Nafpaktos bay coasts at the westerly part of the Gulf of Corinth, under southwesterly wind, and to the south of Rio cape at the front of the city of Patras, under northeasterly wind. Concerning with the central cyclonic eddy, according to numerical simulations it develops exclusively during the flood tide under the simultaneous action of northeasterly winds. The numerical predictions were validated against satellite images of the surface temperature field determined by NOAA-6 and NOAA-7 which closely confirm the simulation results. Finally, the simulated barotropic and baroclinic flow fields are applied to the calculation of the currents near the port of Patras and to the advection and diffusion of the treated sewage effluents disposed of near the southeasterly coast of the Gulf, near the city of Patras.

Les superpositions d'ondes modulées en amplitude et en fréquence (modes AM--FM) sont couramment utilisées pour modéliser de nombreux signaux du monde réel : cela inclut des signaux audio (musique, parole), médicaux (ECG), ou diverses séries temporelles (températures, consommation électrique). L'objectif de ce travail est l'analyse et la compréhension fine de tels signaux, dits "multicomposantes" car ils contiennent plusieurs modes. Les méthodes mises en oeuvre vont permettre de les représenter efficacement, d'identifier les différents modes puis de les démoduler (c'est-à-dire déterminer leur amplitude et fréquence instantanée), et enfin de les reconstruire. On se place pour cela dans le cadre bien établi de l'analyse temps-fréquence (avec la transformée de Fourier à court terme) ou temps-échelle (transformée en ondelettes continue). On s'intéressera également à une méthode plus algorithmique et moins fondée mathématiquement, basée sur la notion de symétrie des enveloppes des modes : la décomposition modale empirique. La première contribution de la thèse propose une alternative au processus dit ''de tamisage'' dans la décomposition modale empirique, dont la convergence et la stabilité ne sont pas garanties. Á la place, une étape d'optimisation sous contraintes ainsi qu'une meilleure détection des extrema locaux du mode haute fréquence garantissent l'existence mathématique du mode, tout en donnant de bons résultats empiriques. La deuxième contribution concerne l'analyse des signaux multicomposantes par la transformée de Fourier à court terme et à la transformée en ondelettes continues, en exploitant leur structure particulière ''en ridge'' dans le plan temps-fréquence. Plus précisément, nous proposons une nouvelle méthode de reconstruction des modes par intégration locale, adaptée à la modulation fréquentielle, avec des garanties théoriques. Cette technique donne lieu à une nouvelle méthode de débruitage des signaux multicomposantes. La troisième contribution concerne l'amélioration de la qualité de la représentation au moyen de la ''réallocation'' et du ''synchrosqueezing''. Nous prolongeons le synchrosqueezing à la transformée de Fourier à court terme, et en proposons deux extensions inversibles et adaptées à des modulations fréquentielles importantes, que nous comparons aux méthodes originelles. Une généralisation du synchrosqueezing à la dimension 2 est enfin proposée, qui utilise le cadre de la transformée en ondelettes monogène.

Thesis (MPhil)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Global economic conditions are forcing donor and development agencies to reduce aid to developing countries and communities. This reduction is resulting in less developmental programmes for disadvantaged communities. To ensure that developmental programmes are implemented successfully and cost effectively, implementing agents will have to ensure that they improve their developmental communication. It is also becoming important that those who are to benefit from developmental programmes convey or identify exactly what their needs are. There should be very little speculation from development agencies about what the needs of the disadvantaged are. It is becoming necessary to review current developmental tools, methods and systems, and also to explore what other measures can be applied to ensure that speculation or time and money wasting exercises are eliminated. This study attempts to look at two things that will influence effective development communication. The first is to examine if community radio is still as an efficient developmental communication tool as perhaps two decades ago. Secondly, it looks at the possibility to tailor-make information for those who need develop, especially in the context of evolving technology.

Quando se refere à adoção de recursos tecnológicos nesta etapa do ciclo de vida da edificação, é comum relacioná-los a métodos tradicionais de operação, uma grande quantidade de documentos, que geralmente não são achados quando necessário, ou recursos utilizados para desenvolver a manutenção preditiva. Este cenário não é diferente na Faculdade de Arquitetura da UFBA (FAUFBA), onde os processos de operação e manutenção seguem padrões tradicionais, de pouca eficiência e eficácia, que dependem de departamentos como a Superintendência de Meio Ambiente e Infraestrutura da UFBA (SUMAI), responsável pela manutenção e conservação dos campi de Salvador: campus Federação / Ondina, campus do Canela, das unidades dispersas e também do campus Anísio Teixeira em Vitória da Conquista. O presente trabalho aborda a utilização da tecnologia CAFM em Instituições de Ensino Superior. Para tanto, foram analisados estudos de caso sobre a aplicação de CAFM na operação e na manutenção de Universidades nacionais e no exterior. Foram identificadas as dificuldades e a metodologia adotada para a implementação da tecnologia, que propõe a concentração de informações essenciais ao processo de gestão da edificação. Diante de recursos promissores, desde a gestão de instalações físicas à gestão de pessoas, a FAUFBA foi utilizada como objeto de trabalho para a implementação do Sistema de Alocação de Espaços em uma aplicação de Facilities Management. Para este propósito, foram utilizados modelos BIM das edificações que compõem a FAUFBA para a realização de testes. Ressaltase a importância da precisão dos dados alfanuméricos ou geométricos, visto que, este é um sistema de banco de dados espacialmente referenciado, ou seja, um repositório de informações, que é de grande valor durante a etapa de operação e manutenção da edificação. / . / In general, it is difficult to associate such advanced technology resources with the way that operation and maintenance in today's buildings is conducted. Regarding the adoption of technological resources at this stage of edification life cycle, it is common to relate them to traditional methods of operation. Usually a large number of documents are not found when necessary, or resources used to develop predictive maintenance. This scenario is no different in the Faculty of Architecture of UFBA (FAUFBA), where operation and maintenance processes follow traditional, lowefficiency and efficacious standards, which depend on departments such as the UFBA Superintendence of the Environment and Infrastructure (SUMAI), responsible for the maintenance and conservation of the campuses of Salvador: Federação / Ondina campus, Canela campus, dispersed units and also the Anísio Teixeira campus in Vitória da Conquista. The present work deals with the use of CAFM technology in Higher Education Institutions. Therefore, we analyzed case studies on the application of CAFM in the operation and maintenance of national universities and abroad. We identified the difficulties and the methodology adopted for the implementation of the technology, which proposes the concentration of essential information to the process of building management. Considering the necessities of the university with regards of management of physical facilities and personnel, it was used as a work object for the implementation of the Space Allocation System, using Facilities Management. For this purpose, BIM models of the buildings that make up the FAUFBA were used to carry out tests. The importance of the precision of the alphanumeric or geometric data is emphasized, since this is a spatially referenced database system - a repository of information, which is of great value during the stage of operation and maintenance of the building.

Considerando canais de desvanecimento WeibulI, devido à ausência de um modelo físico para tais canais, estatísticas conjuntas de duas variáveis WeibuII correlacionadas foram obtidas em forma fechada e em função de parâmetros físicos bem conhecidos. Outra estatística encontrada foi a taxa de cruzamento de nível e a duração média de desvanecimento usando diversidade com dois ramos para canais WeibuII correlacionados, desbalanceados e não-idênticos. Além disso, uma caracterização do comportamento do processo de fase e de sua derivada temporal para sinais WeibuII foi realizada. Analisando canais de desvanecimento Nakagami-m, uma expressão simples e em forma fechada para a taxa de cruzamento de fase generalizada foi obtida. Resultados de simulação completamente validaram a formulação proposta. Além disso, novas estatísticas em forma fechada para a envoltória, para as componentes em fase e em quadratura, para a fase e para suas respectivas derivadas temporais foram obtidas / Abstract: This dissertation provides an analysis of the higher order statistics for WeibuII and Nakagami-m fading channels. Conceming WeibuII fading channels, due to the absence of a fading model related of such channels, joint statistics for two correlated WeibuII variates were obtained in cIosed-form and in terms of welI-known physical parameters. Other statistics found were the levei crossing rate and the average fade duration for unbalanced, non-identical, correlated WeibuII channels operating over two branches of diversity. Furthermore, a characterization of the behaviour of the phase process and its time derivative for WeibuII signals was accomplish. Conceming Nakagami-m fading channeIs, a simple and cIosed-form expression for the generalized phase crossing rate was obtained. Results of simulation thoroughly validated the formulation proposed. Moreover, new cIosed-form statistics for the envelope, for the in-phase and quadrature components, for the phase and its respective time derivative were derived. / Mestrado / Telecomunicações e Telemática / Mestre em Engenharia Elétrica

O estudo do fenômeno de expansão em solos argilosos tem-se restringido, na maioria das vezes, a estudos laboratoriais referentes ao comportamento mecânico do solo e as correlações com as propriedades índices e as classificações geotécnicas. Poucos são os estudos na área de mapeamento geotécnico em média e grande escala, existindo um vazio nas metodologias de mapeamento geotécnico no que se refere a esta classe de solos. Durante o desenvolvimento desta pesquisa sobre as características expansivas da Fm. Libertad, Quaternário (Uruguai), foram combinados os produtos obtidos das técnicas de mapeamento com os propriedades identificadas nos ensaios de caracterização e as medidas de expansão. A técnica de avaliação de terreno usando Landforms para separar unidades homogêneas, resultou em um grande auxílio permitindo direcionar os trabalhos e observações de campo e diminuir o numero de amostras a serem coletadas. O ensaio de caracterização da Capacidade de Troca Catiônica (CTC) da fração argila, usando a técnica de Azul de Metileno, mostrou-se coincidente com a identificação de argilo-minerais usando Difração de Raios X (DRX). Esses dados, associados aos valores de Pressão de Expansão e Expansão livre de amostra indeformadas, com umidade natural e secas ao ar, e de amostras compactadas com diferentes massas específicas seca (pd) e umidade constante (w=15%) permitiram identificar unidades com diferentes potenciais de expansão na Fm. Libertad. A combinação desses dados permitiu a produção da Carta de Potencial de Expansão do Solos, numa região de desenvolvimento urbano no Município de Montevidéu, Uruguai. Este documento fornece aos planejadores do uso e ocupação da área o conhecimento dos diferentes graus de restrição que devem ser levados em conta devido à presença de solos potencialmente expansivos. Elaborou-se uma proposta metodológica para a execução de trabalhos de mapeamento geotécnico de solos expansivos. / The swelling phenomenon of the clay soils has been studied mainly in laboratory with the objective of undestand the behavior of the soil and the correlations with the index properties and with the geotechnical classifications. In Engineering Geotechnical Mapping there is a lack of methodology about swell soil mapping in medium or large scale. In this research the swelling characteristics of the Libertad Formation (Uruguay) were studied by combination of the information obtained in the Engineering Geotechnical Mapping (scale 1:10.000) and the soil properties identified in the characterization and swelling tests. The technique of land evaluation using Landforms to separate homogeneous units, it resulted in a great aid allowing to guide the works and field observations and to reduce the number of samples to be collected. The characterization tests of cationic exchange capacity (CEC) of the clay, using the technique of adsorption of methilene blue, it was shown coincident with the identification of clay using X-Ray Diffraction (XRD). The swelling potentials of the Libertad Formation were determined based in the information of the values of swelling pressure and free swelling from undisturbed samples, both with natural moisture contents and air dried, besides the samples compacted with different apparent specific gravity (pd) and with constant moisture content (w= 15%). This procedure allowed the production of the Swelling Potential Chart of the soil in an suburban area of Montevideo City, Uruguay. This document can supply the information to the management of the area taken in account the different swelling potential of the soils. Finally it is presented a methodology to carry out Engineering Geological Mapping of the swelling soils.

The main theme of this work is the detection of overlaps in NGS data. The work contains an overview of NGS sequencing technologies that are the source of NGS data. In the thesis, the problem of overlapping detection is generally defined. Next, an overview of the available algorithms and approaches for detecting overlaps in NGS data is created. Principles of these algorithms are described herein. In the second part of this work a suitable tool for detecting approximate overlaps in NGS data is designed and its implementation is described herein. In conclusion, the experiments performed with this tool and the conclusions that follow are summarized and described.
