This thesis explores, through a number of production andperception studies, the nature of the voice source signal andhow it varies in spoken communication. Research is alsopresented that deals with the techniques and methodologies foranalysing and synthesising the voice source. The main analytictechnique involves interactive inverse filtering for obtainingthe source signal, which is then parameterised to permit thequantification of source characteristics. The parameterisationis carried by means of model matching, using the four-parameterLF model of differentiated glottal flow. The first three analytic studies focus on segmental andsuprasegmental determinants of source variation. As part of theprosodic variation of utterances, focal stress shows for theglottal excitation an enhancement between the stressed voweland the surrounding consonants. At a segmental level, the voicesource characteristics of a vowel show potentially majordifferences as a function of the voiced/voiceless nature of anadjacent stop. Cross-language differences in the extent anddirectionality of the observed effects suggest differentunderlying control strategies in terms of the timing of thelaryngeal and supralaryngeal gestures, as well as in thelaryngeal tensions settings. Different classes of voicedconsonants also show differences in source characteristics:here the differences are likely to be passive consequences ofthe aerodynamic conditions that are inherent to the consonants.Two further analytic studies present voice source correlatesfor six different voice qualities as defined by Laver'sclassification system. Data from stressed and unstressedcontexts clearly show that the transformation from one voicequality to another does not simply involve global changes ofthe source parameters. As well as providing insights into theseaspects of speech production, the analytic studies providequantitative measures useful in technology applications,particularly in speech synthesis. The perceptual experiments use the LF source implementationin the KLSYN88 synthesiser to test some of the analytic resultsand to harness them to explore the paralinguistic dimension ofspeech communication. A study of the perceptual salience ofdifferent parameters associated with breathy voice indicatesthat the source spectral slope is critically important andthat, surprisingly, aspiration noise contributes relativelylittle. Further perceptual tests using stimuli with differentvoice qualities explore the mapping between voice quality andits paralinguistic function of expressing emotion, mood andattitude. The results of these studies highlight the crucialrole of voice quality in expressing affect as well as providingpointers to how it combines withf0for this purpose. The last section of the thesis focuses on the techniquesused for the analysis and synthesis of the source.

The purpose of this study is to design, develop and evaluate an electronic performance support system (EPSS) for the crime scene investigation unit (CSI). For this purpose, a sequential explanatory strategy as a procedure of the mixed method design was used in analysis and evaluation of the EPSS. The research was composed of three main phases: analysis / design, development and implementation, and evaluation of the EPSS. In first phase composed of performance and cause analyses, the CSI Unit&rsquo / s existing information, and contributing causal performance factors based on Gilbert&rsquo / Behavior Engineering Model were explored. In performance analysis phase, official documentation of the CSI Unit was reviewed. As for cause analysis, the survey and focus group interviews were conducted to 1176 and 22 CSI officers, respectively. These data were analyzed using with both quantitative and qualitative methods to facilitate the selection of the most appropriate intervention and its components. Analyses results revealed that 14 basic influences grouped under the workplace and competency on human behavior impacted performance of the officers. Based on these results, an EPSS composed of intrinsic, extrinsic and external levels, and support components was designed and developed in the second phase. Having been implemented, the evaluation of the EPSS based on the Kirkpatrick&rsquo / Four Levels of Evaluation Model was conducted v to determine the overall impact, perceived benefits, and effectiveness of the intervention in third phase. In this phase, a survey, interviews, computer logs and a checklist were used so as to assess the accomplishment of the EPSS. While the survey and the checklist were administered to the 191 officers and 2 experts from the field, the interviews were conducted with 12 officers. Evaluation results admitted that the CSI officers&rsquo / reactions were very positive to the EPSS. While, an intrinsic support made a major contribution to their productivity, establishing standardization would be perceived as the major impact of the EPSS. Lastly, increasing identity and simplifying criminal justice system were the two main impact factors on the society that the system would influence positively.

This case study, of veterinary education at Glasgow between 1949 and 2006, was undertaken to provide an illustrative account of learning and teaching practices over time. Ultimately the aim was to inform discussions on curriculum reshaping in undergraduate veterinary education at Glasgow. A questionnaire was distributed to 2360 alumni, 513 students and 50 teachers, to obtain quantitative data on the availability and perceived usefulness of different educational methods and technologies, analysed using SPSS. Qualitative data were sought principally through ten student focus groups and interviews with over thirty current and former staff, theoretically coded using NVivo. Questionnaire responses (from 11.5% of alumni, 23.8% of students and 72% of teachers invited to participate) revealed that lectures, printed notes, tutorials, practical classes and clinical training were used consistently over time and rated highly by stakeholders, confirming the importance of didactic teaching methods coupled with discussion and practical hands-on experience. The focus groups with students highlighted their strong desire for earlier clinical training, with the recognition that a case-based approach resulted in more meaningful learning. The interviews with staff revealed that whilst all staff welcomed the opportunity for increased vertical integration, problem-based learning was rejected as a wholesale solution. Highlights of the school’s curricular innovations to date include the clinico-pathological integrated sessions, the lecture-free final year, and the introduction of a veterinary biomolecular sciences course that allowed for a seamless vertical integration in years 1 to 4. However, recent efforts to implement self-directed learning and assessment strategies have been hampered by the fact that these were isolated innovations set within a traditional teacher-centred paradigm. There was little support among stakeholders for undergraduate specialisation. There is still a perceived need for veterinarians to have omni-potential – if not to be omnicompetent. However, it is recommended that the current system of tracking be replaced with a more streamlined core-elective system, to allow students to pursue specific topics of interest in the later years of the course. Teachers and students cited attributes of ‘good’ teachers. These generally did not change over time, although technologies did change. Good communication appears to be central to good teaching, with an in-borne desire to enthuse and motivate students to learn for the pleasure of learning rather than the need to hurdle-jump examinations. Both teachers and students cited good teaching characteristics in terms of the teacher as authority and motivator, rather than as a facilitator of independent learning, reflecting the nature of the traditional, didactic course. There was little evidence of pedagogical change resulting from technological innovations. If anything, newer technologies compounded surface learning approaches and low level cognitive processing, rather than promoting deep learning and higher order thinking skills. Identified barriers to teaching innovations included lack of time, reward and support (for teachers and students). Future curricular innovation will require a substantial investment in the scholarship of teaching – rewarding staff for excellence in teaching, putting it on a par with research excellence, and ensuring the necessary support mechanisms and infrastructure are in place to ensure the success of a self-directed learning curriculum. A guided discovery learning curriculum is recommended, a compromise between traditional teaching and a fully problem-based curriculum. The study did not specifically focus on assessment, but it is recommended that learning, teaching and assessment practices should be constructively aligned.

El presente análisis parte de un estudio contrastivo, el cual consta de una clasificación de los títulos literarios traducidos del castellano al sueco entre los años 1988 y 2007. Hemos clasificado los títulos según el grado de modificación semántica entre el título original y el título traducido. La parte cualitativa consta del análisis de algunos títulos del estudio contrastivo, con un enfoque particular en los títulos que han sido modificados, los efectos que las modificaciones conllevan, si se pueden motivar y por qué. Parece haber un respeto profundo por el título original de una obra, ya que un 48% de los 208 títulos traducidos del estudio equivalen semánticamente a los títulos originales. Sin embargo, un 52% de los títulos ha sido modificado al ser traducido. Al analizar algunos casos de manera más profunda queda claro que más bien que ser cambios arbitrarios, las modificaciones lingüísticas pueden tener explicaciones sintácticas, estilísticas y/o culturales. El deseo de reconstruir significado connotativo y cierto nivel estilístico ha sido la guía en muchos casos. En efecto, una equivalencia formal, o traducir de manera más literal, no siempre es deseable, aunque sea una opción posible en la mayoría de los casos.

Der Bauschmuck des Jupitertempels in Baalbek ist durch sechs noch stehende Säulen mitsamt Gebälk sowie durch zahlreiche im Gelände verstreute Fragmente bezeugt. Durch die hier vorliegenden Untersuchungen konnten nun erstmals auch Fragmente nachgewiesen werden, die zum Aufbau der ansonsten verlorenen Tempelcella gehörten. Über eine möglichst umfassende Katalogisierung konnte der Materialbestand weit über das bisher bekannte Maße gesichert werden, so daß zum Beispiel mit 23 statt der in der Forschung bisher üblichen 2 Kapitelle gearbeitet werden konnte. Der Fokus der Arbeit liegt zunächst auf der Darstellung und Beschreibung des Tempels sowie seiner kulturellen und bauhistorischen Verortung in Baalbek selbst. Als feste Referenzpunkte außerhalb der Stadt wurden der Mars-Ultor- Tempel in Rom sowie der Bel-Tempel von Palmyra gewählt. Durch diese Vergleiche und durch einen erstmals in der Forschungsgeschichte vorgenommenen Vergleich der einzelnen Ornamentzonen untereinander konnte eine neue Datierung vorgenommen werden, wodurch der Aufbau und die Fertigstellung des Baus in die 2. Hälfte des 1. Jhs. n. Chr. zu rücken sind. Die Interpretation der Architekturornamentik führte zu mehreren, zum Teil völlig neuen Ergebnisse. Der große und schon vielfach bemerkte Reichtum in der Ausarbeitung des Bauschmucks zeigt das große Können, ein umfangreiches Repertoire und vor allem eine große Freiheit der ausführenden Steinmetzen, die wohl eher lokaler Abstammung waren. Darüber hinaus ist der extra für den Tempel entworfene Fries eine politische Aussage der Colonia Beirut/Heliopolis, mit dem die neu erworbene Stellung im Machtgefüge der levantinischen Städte demonstriert werden soll. Die immer wieder auftretende Unfertigkeit bei der Fertigstellung der Ornamentik ist systematisch und läßt sich mit den umfassenden finanziellen Problemen im römischen Steuerwesen beim Übergang zwischen der neronischen und der flavischen Epoche begründen. / The architectural decoration of the temple of Jupiter in Baalbek is testified by six still standing columns with their entablature and numerous fragments in the area around. This study presents for the first time also fragments from the construction of the otherwise lost cella of the temple. By building a nearly complete catalog of the fragments it was possible to secure the material stock far beyond it was known by now, so for example it was possible to work with 23 instead of the 2 capitals that had been used in former research. The mainly focus of the work is on the representation and description of the temple and its cultural and architectural location in the city of Baalbek. The temple of Mars-Ultor in Rome and the temple of Bel in Palmyra were chosen as fixed reference points. Through these comparisons and through a comparison of the individual ornamental zones with each other for the first time in the history of research, a new dating could be established, which places the construction and completion of the building in the 2nd half of the 1st century AD. The interpretation of architectural ornamentation led to several completely new results. The great and already noticed wealth in the elaboration of architectural ornamentation shows the great skill, an extensive repertoire and above all a great freedom of the executing stonemasons, who were probably of more local origin. Furthermore the frieze was specially designed for the temple and is a political statement of the Colonia Beirut/Heliopolis, which is intended to demonstrate the newly acquired position in the administratic structure of the Levantine cities. The recurrent incompleteness in the ornamentation is systematic and can be explained by the financial problems in the roman state finances during the transition between the Neronic and Flavian eras.The architectural decoration of the temple of Jupiter in Baalbek is testified by six still standing columns with their entablature and numerous fragments in the area around.

L’analyse des signaux de parole permet de comprendre le fonctionnement de l’appareil vocal, mais aussi de décrire de nouveaux paramètres permettant de qualifier et quantifier la perception de la voix. Dans le cas de la parole expressive, l'intérêt se porte sur des variations importantes de qualité vocales et sur leurs liens avec l’expressivité et l’intention du sujet. Afin de décrire ces liens, il convient de pouvoir estimer les paramètres du modèle de production mais aussi de décomposer le signal vocal en chacune des parties qui contribuent à ce modèle. Le travail réalisé au cours de cette thèse s’axe donc autour de la segmentation et la décomposition des signaux vocaux et de l’estimation des paramètres du modèle de production vocale : Tout d’abord, la décomposition multi-échelles des signaux vocaux est abordée. En reprenant la méthode LoMA qui trace des lignes suivant les amplitudes maximum sur les réponses temporelles au banc de filtre en ondelettes, il est possible d’y détecter un certain nombre de caractéristiques du signal vocal : les instants de fermeture glottique, l’énergie associée à chaque cycle ainsi que sa distribution spectrale, le quotient ouvert du cycle glottique (par l’observation du retard de phase du premier harmonique). Cette méthode est ensuite testée sur des signaux synthétiques et réels. Puis, la décomposition harmonique + bruit des signaux vocaux est abordée. Une méthode existante (PAPD - Périodic/APériodic Décomposition) est adaptée aux variations de fréquence fondamentale par le biais de la variation dynamique de la taille de la fenêtre d’analyse et est appelée PAP-A. Cette nouvelle méthode est ensuite testée sur une base de signaux synthétiques. La sensibilité à la précision d’estimation de la fréquence fondamentale est notamment abordée. Les résultats montrent des décompositions de meilleures qualité pour PAP-A par rapport à PAPD. Ensuite, le problème de la déconvolution source/filtre est abordé. La séparation source/filtre par ZZT (zéros de la transformée en Z) est comparée aux méthodes usuelles à base de prédiction linéaire. La ZZT est utilisée pour estimer les paramètres du modèle de la source glottique via une méthode simple mais robuste qui permet une estimation conjointe de deux paramètres du débit glottique : le quotient ouvert et l'asymétrie. La méthode ainsi développée est testée et combinée à l’estimation du quotient ouvert par ondelettes. Finalement, ces trois méthodes d’estimations sont appliquées à un grand nombre de fichiers d’une base de données comportant différents styles d’élocution. Les résultats de cette analyse sont discutés afin de caractériser le lien entre style, valeur des paramètres de la production vocale et qualité vocale. On constate notamment l’émergence très nette de groupes de styles. / Analysis of speech signals is a good way of understanding how the voice is produced, but it is also important as a way of describing new parameters in order to define the perception of voice quality. This study focuses on expressive speech, where voice quality varies a lot and is explicitly linked to the expressivity or intention of the speaker. In order to define those links, one has to be able to estimate a high number of parameters of the speech production model, but also be able to decompose the speech signal into each parts that contributes to this model. The work presented in this thesis addresses the segmentation of speech signals, their decomposition and the estimation of the voice production model parameters. At first, multi-scale analysis of speech signals is studied. Using the LoMA method that traces lines across scales from one maximum to the other on the time domain response of a wavelet filter bank, it is possible to detect a number of features on voiced speech, namely : the glottal closing instants, the energy associated to each glottal cycle, the open quotient (by estimating the time delay of the first harmonic). This method is then tested on both synthetic and real speech. Secondly, harmonic plus noise decomposition of speech signals is studied. An existing method (PAPD standing for Periodic/Aperiodic Decomposition) is modified to dynamically adapt the analysis window length to the fundamental frequency (F0) of the signal. The new method is then tested on synthetic speech where the sensibility to the estimation error on F0 is also discussed. Decomposition on real speech, along with their audio files, are also discussed. Results shows that this new method provides better quality of decomposition. Thirdly, the problem of source/filter deconvolution is addressed. The ZZT (Zeros of the Z Transform) method is compared to classical methods based on linear prediction. ZZT is then used for the estimation of the glottal flow parameters with a simple but robust method based on the joint estimation of both the open quotient and the asymmetry. The later method is then combined to the estimation of the open quotient using wavelet analysis. Finally, the three estimation methods developed in this thesis are used to analyze a large number of files from a database presenting different speaking styles. Results are discussed in order to characterize the link between style, model parameters and voice quality. We especially notice the neat appearance of speaking style groups

Operational transconductance amplifier and capacitor (OTA-C) filters have outstood among different types of filter due to high frequency and low power capabilities in the main stream digital CMOS technology. They have been widely used in computer hard disk drive (HDD) and wireless communication transceivers. OTA-C filters based on cascade and passive ladder simulation are well-known. However, multiple loop feedback (MLF) OTA-C filters which have certain advantages still have the scope for further research. So far there have been no explicit formulas for current-mode leapfrog (LF) filter design and performance evaluation of current-mode MLF OTA-C filters are still lacking. From application viewpoints, read channels for computer hard disk drives require very high frequency continuous-time filters. This automatically disqualifies active- RC/MOSFET-C filters and OTA-C filters become the only solution. In wireless communications, active-RC/MOSFET-C filters have been proved useful for mobile systems whose baseband frequency falls below a few MHz. However, for wireless LANs with the frequency of several tens of MHz, OTA-C filters are a strong candidate. Whilst in HDD read channels, cascaded OTA-C architectures have been most utilized and in wireless receivers, OTA-C structures based on ladder simulation have been popular, MLF OTA-C filters have not been practically used in either of the applications. This thesis describes some novel designs and applications of multiple loop feedback OTA-C filters with extensive CMOS simulations. Analogue filters for computer hard disk drive systems are first reviewed; the state of the art and design considerations are provided. Three VHF linear phase lowpass OTA-C filters are then designed, which include a seventh-order and a fifth-order current-mode filter based on the follow-the-leader-feedback (FLF) structure and a seventh-order voltage-mode filter using the inverse FLF (IFLF) configuration. These filters all have very low power consumption. The synthesis and design of general current-mode LF OTA-C filters are conducted next. Iterative design formulas for both all-pole and finite-zero functions are derived and explicit formulas for up to sixth-orders are given. These formulas are very easy to use for designing any type of characteristics. Subsequently, linear phase lowpass OTA-C filter design for HDD read channels using LF structures are investigated in details. A current-mode filter and a voltage-mode filter using the fifth-order LF structure are presented. The two filters can operate up to 800MHz and have very small passband phase ripple. Analogue filters for wireless communication baseband applications are also reviewed thoroughly in this thesis, where the design of a fourth-order current-mode FLF Butterworth lowpass OTA-C filter for multi-standard receivers is presented. Then two fifth-order current-mode elliptic lowpass OTA-C filters based on respective LF and FLF structures for wireless communication baseband are designed. Fifth-order voltage-mode IFLF and LF elliptic lowpass filters are also presented. All these MLF baseband filters designed can operate up to 40MHz to cover all important wireless and mobile standards. Simulations show that the LF structures have better dynamic range and stopband attenuation performances than the FLF and IFLF configurations.
