Ferré, Alexis. "Etude CFD et expérimentale d'un stockage thermique de type thermocline." Electronic Thesis or Diss., Pau, 2024. http://www.theses.fr/2024PAUU3023.
Full textAbstract:
Le stockage d'énergie est essentiel à la transition énergétique car il permet de découpler la production de l'énergie de sa consommation. Le stockage de chaleur thermocline en eau, utilisé dans les réseaux de chaleur à moyenne ou basse température, repose sur la stratification thermique dans une cuve. Les performances de ce type de stockage sont fortement liées à la bonne stratification du fluide qui peut être perturbée par l'injection et le soutirage du liquide, des aspects peu explorés dans la littérature.L'objectif de cette thèse est de modéliser un tel stockage de manière fiable pour analyser la distribution du fluide. En effet, le but est de mieux appréhender les phénomènes physiques gouvernant la thermocline pendant les cycles de fonctionnement et d'accroître ses performances énergétiques par un design ou un pilotage amélioré. Pour ce faire, des études numériques utilisant la CFD (Computational Fluid Dynamics) ont été réalisées et comparées à des données expérimentales disponibles dans la littérature et obtenues via une nouvelle section d'essais.Dans un premier temps, un modèle CFD a été développé basé sur un cas expérimental existant de la littérature. Dans un stockage thermocline en eau, il y a bien souvent coexistence entre une région laminaire dans la cuve et turbulente à proximité des distributeurs. Cette coexistence est un enjeu majeur de la modélisation car la plupart des modèles de turbulence ne sont pas capables de représenter fiablement la transition d'un écoulement turbulent vers laminaire. Pour ces travaux, une méthode statistique RANS (Reynolds Average Numerical Simulation) est adoptée et le modèle k-omega-SST est sélectionnée car il permet de représenter les écoulements en proche paroi. Concernant la flottabilité, il existe deux méthodes pour considérer ses effets : utiliser une masse volumique variable dans l'ensemble des équations, ou constante sauf dans le terme de flottabilité . Cette dernière est connue sous le nom de l'approximation de Boussinesq mais n'est valable que sur une faible gamme de ΔT. La précision de l'approximation de Boussinesq a été remise en question et une approche au second ordre de ce modèle est employée. Celle-ci permet d'obtenir le même terme de flottabilité qu'un modèle à masse volumique variable mais avec un temps de calcul réduit de moitié. La comparaison avec des données expérimentales a permis de souligner l'impact de l'état initial en température (stockage stratifié ou homogène). Une étude exploratoire de l'impact d'une injection progressive selon une rampe en débit a montré son impact sur la réduction de l'épaisseur de la thermocline au moment de sa création.Dans une démarche de validation du modèle et de vérification des observations numériques, un nouveau dispositif expérimental a été conçu. Celui-ci mesure la température grâce à 300 thermocouples disposés dans la cuve et permet un contrôle précis des conditions opératoires. Des études en phase statiques pour évaluer les pertes thermiques ont été réalisées. Des études dynamiques ont permis de faire varier les paramètres opératoires pertinents : la vitesse de propagation axiale, l'écart de température, le dispositif de soutirage ou encore l'injection progressive. Pour ce système, les résultats montrent qu'il est possible d'obtenir une stratification à forte vitesse (> 2 mm/s) tant que le ΔT est suffisamment élevé.Enfin, l'écoulement dans la section d'essais a été étudié numériquement avec un modèle CFD actualisé. Les champs de variables ont montré que les résultats numériques et expérimentaux sont cohérents, en particulier lors de la formation de la thermocline. Toutefois, un excès de diffusion lors de la propagation du gradient thermique à faible débit est notable. Pour tous les essais réalisés les écarts expérimentaux et numériques ont été quantifiés: à l'exception des conditions critiques, l'écart sur l'épaisseur de thermocline est de ±50% et se situe entre 0 et -10% pour le taux de restitution<br>Energy storage is essential to the energy transition as it allows decoupling energy production from its consumption. Water-based thermocline heat storage, used in medium or low-temperature heating networks, relies on thermal stratification in a tank. The performance of this type of storage is strongly linked to the proper stratification of the fluid, which can be disrupted by the injection and extraction of the liquid, aspects that are scarcely explored in the literature.The objective of this thesis is to reliably model such storage to analyze the fluid distribution. The aim is to better understand the physical phenomena governing the thermocline during operating cycles and to enhance its energy performance through improved design or control. To achieve this, numerical studies using CFD (Computational Fluid Dynamics) were conducted and compared with experimental data available in the literature and obtained via a new experimental setup.Initially, a CFD model was developed based on an existing experimental case from the literature. In water thermocline storage, there is often coexistence between a laminar region in the tank and a turbulent region near the distributors. This coexistence is a major challenge in modeling because most turbulence models cannot reliably represent the transition from turbulent to laminar flow. For this work, a RANS (Reynolds Average Numerical Simulation) statistical method is adopted, and the k-omega-SST model is selected as it can represent near-wall flows. Regarding buoyancy, there are two methods to consider its effects: using a variable density in all equations or a constant density except in the buoyancy term. The latter is known as the Boussinesq approximation but is only valid over a narrow range of ΔT. The accuracy of the Boussinesq approximation has been questioned, and a second-order approach of this model is employed. This allows obtaining the same buoyancy term as a variable density model but with a calculation time reduced by half. Comparison with experimental data highlighted the impact of the initial temperature state (stratified or homogeneous storage). An exploratory study of the impact of progressive injection according to a flow ramp showed its effect on reducing the thermocline thickness at the time of its creation.As part of the model validation and verification of numerical observations, a new experimental setup was designed. It measures the temperature using 300 thermocouples placed in the tank and allows precise control of operating conditions. Static phase studies to evaluate thermal losses were conducted. Dynamic studies allowed varying relevant operating parameters: axial propagation speed, temperature difference, extraction device, and progressive injection. For this system, the results show that it is possible to obtain stratification at high speed (> 2 mm/s) as long as the ΔT is sufficiently high.Finally, the flow in the test section was numerically studied with an updated CFD model. The variable fields showed that the numerical and experimental results are consistent, especially during the formation of the thermocline. However, excessive diffusion during the propagation of the thermal gradient at low flow is notable. For all the tests carried out, the experimental and numerical discrepancies were quantified: except for critical conditions, the discrepancy in thermocline thickness is ±50% and ranges from 0 to -10% for the restitution rate

Full textAbstract:
Text-till-talsynteser (eng. Text-to-speech, TTS), med andra ord digitalt skapade röster, har blivit en naturlig del av våra dagliga liv. Vi hör dem i kollektivtrafiken, när vi interagerar med digitala assistenter och när människor som saknar en egen röst använder dem för att kommunicera. Dessa artificiella röster har, precis som riktiga röster, olika egenskaper som påverkar hur de låter och uppfattas. Det är därför intressant att förstå vilka TTS-synteser som användare föredrar i olika sammanhang. I denna studie undersöktes huruvida det finns en preferens för olika kön hos instruerande TTS-synteser. I studien fick 46 deltagare spela ett spel där målet var att fullfölja ett antal upplästa instruktioner genom olika knapptryck på skärmen. Spelet var uppdelat i två omgångar, där instruktören i ena omgången var en TTS-syntes med en manlig röst och i den andra en kvinnlig. Vilken TTS-syntes som började och ordning av instruktioner slumpades för deltagarna. Efter spelad omgång svarade deltagarna på en enkät om upplevda röstegenskaper hos instruktören. När sista omgången fullföljts besvarades även en avslutande enkät där det bland annat frågades vilken av TTS-synteserna de föredrog, följt av en kvalitativ fråga där de fick motivera sitt svar. Svaren analyserades sedan genom ett statistiskt test och en kvalitativ analys. Studien kunde ej påvisa någon preferens för kön hos instruerande TTS-synteser. Istället visade resultatet att testpersonerna har individuella preferenser och åsikter om rösterna, även om det verkade finnas viss konsensus om somliga upplevda röstegenskaper hos TTS-synteser.<br>Text-to-speech synthesis (TTS), in other words digitally created voices, has become a natural part of our daily lives. We hear them in public transport, when we interact with digital assistants and when people who do not have their own voice use them to communicate. These artificial voices, just like real voices, have different properties that affect how they sound and are perceived. It is thereby interesting to understand which TTS-synthesis users prefer in different contexts. This study examined whether there is a preference for different genders in instructional TTS-synthesis. In the study, 46 participants played a game where the goal was to complete a number of read out loud instructions through various key presses on the screen. The game was divided into two rounds, where the instructor in one round was a TTS-synthesis with a male voice and female in the other one. Which TTS-synthesis started and the order of instructions was randomized for each participant. Upon completing the round, the participants answered a questionnaire about perceived voice characteristics of the instructor. When the final round was completed, a final questionnaire was also answered in which, among other things, it was asked which of the TTS-syntheses the test subjects preferred, followed by a qualitative question in which they were asked to justify their answer. The answers were then analyzed through a statistical test and a qualitative analysis. The study could not demonstrate any gender preference in instructional TTS-synthesis. Instead, the results showed that the test subjects have individual preferences and opinions about the voices, even though there seemed to be some consensus about some of the perceived voice characteristics of the TTS-syntheses.

Teixeira, João Paulo. "A prosody model to TTS systems." Doctoral thesis, Universidade do Porto, Faculdade de Engenharia, 2004. http://hdl.handle.net/10198/1496.
Full textAbstract:
This PhD thesis presents the development of a prosody system for European Portuguese (EP) for text-to-speech (TTS) applications. Basically, TTS systems carry out the automatic utterance of a text and consist in a sequence of several modules. Those modules implement the pre-processing of the text input, the phonetic transcription and the supra-segmental processing that consists in the inclusion of prosodic patterns. The prosody is responsible for a communicative intention and guarantees some naturalness in the uttered speech. The prosodic features consist in the imposition of the timing, characterized by the segmental durations and pauses, the intonation, characterized by the fundamental frequency (F0) curve, and by the intensity curve.
The preparatory work that was fundamental for modelling and testing purposes is presented in the beginning. It starts with a preliminary study about the stressed syllable. This study identifies the variation range of F0, duration and intensity features in stressed syllable along contexts. Then the FEUP-IPB EP speech database that was used in following studies is presented. The database is labelled at the levels of the phoneme, word, sentence and F0. The thesis follows on with the presentation of two algorithms to provide the syllabic splitting of the text and of the phoneme sequences. This chapter ends with a proposed set of rules for the automatic phonetic transcription of the most problematic graphemes in EP.
The proposed prosody model consists of several sub-models, namely, the duration model to predict the segmental durations and the model to predict the F0 pattern.
Two proposals, based in artificial neural networks (ANNs), to predict the segmental durations are presented.
The first proposal consists of one ANN carefully selected concerning its architecture and type as well as the set of input features with the objective of minimizing the error between predicted and measured durations. The second proposal, entitled alternative model, is based on same considerations of the first proposal but uses one dedicated ANN for each phoneme, in a total of 44 ANNs. The alternative model, with dedicated ANNs, improved the final performance.
A model of insertion and prediction of durations of the pauses is proposed, based on a preliminary study over the FEUP-IPB database.
The proposed model to predict the F0 contour is based on the Fujisaki model and consists of two sub-models. One predicts the Phrase Commands’ (PCs) parameters and the other predicts the Accent Commands’ (ACs) parameters.
The PCs and the ACs were manually estimated in 101 paragraphs of the database under the criterion of the minimization of the error between estimated and measured F0 contours.
The prediction of the PCs is performed in two stages. The first stage is carried out by an algorithm responsible for the insertion of the PCs connected to the text and based on a mathematical model obtained from experimental observations. The second stage of the model predicts the PCs amplitude, Ap, and anticipation, T0a, relatively to the initial position. The anticipation allows the determination of the exact position in the speech signal. The two parameters are predicted with ANNs.
A strong connection between ACs and syllables was found in the database. This strong connection justified the adopted methodology of predicting ACs associated with syllables. Therefore, the ACs model consists of one ANN to predict the existence of AC associated with the syllable and other three ANNs to predict the parameter’s amplitude (Aa) and anticipation of the onset (T1a) and offset (T2a) instants.
The final perceptual test using the category-judgment method and the MOS scale resulted in a classification of 4.6 for the natural speech, 4.4 for the estimated F0, 4.2 for predicted durations, 3.1 for the predicted F0 and 2.9 for the complete proposed model (duration and F0 models). The MOS for the complete model is at the ‘Fair’ level.

Full textAbstract:
The purpose of this study was to determine if appraisers using the TTAS in Texas perceived themselves as being objective in the evaluation process. The population for this study was 213 appraisers, both elementary and secondary, chosen randomly from four educational service areas in four regions of Texas. Data were obtained from a 25-item questionnaire mailed to the appraisers. The organization of this study includes a statement of the problem, the research questions, a review of the literature, the methods and procedures used to collect the data, the analysis of the data, and a summary of the findings, conclusions, implications, and recommendations for additional research. Data from the 213 returned questionnaires were treated with the chi-square test of independence. The analysis of data revealed the following: 1. Regardless of the level, elementary or secondary, of the administrator, the majority of respondents held the same views. 2. Regardless of the region of Texas from which the respondents came, the majority of respondents held the same views. 3. Regardless of the number of years of experience of the appraisers, the majority of respondents held the same views. 4. The majority of respondents felt they are objective in their use of the TTAS. The implications are that the TTAS instrument is being used as was its intention, and that the appraisers feel comfortable in the use of the TTAS. Since the TTAS is effective as seen through a majority of respondents, it may be used in future revisions of the current instrument or by other districts as a model by which to begin construction of their own appraisal instruments.

Title: The news betrayal from TT – A quantitative content analysis of TT’s news reporting from the north In the year of 2013 TT-nyhetsbyrån closed down their three local editorial offices in north Sweden with a promise that the news coverage of Norrland would remain the same. In this study we aim to examine if, and how, the journalistic content has changed due to their centralization. Based on theories of media and democracy, the commercialization of journalism and news evaluation, this study investigates different aspects of TT’s journalistic output such as news outlets, news topic, democratic value dimensions, framing, original reporting and sourcing. The material of examination consists of a total of 199 articles which derive from Luleå, Umeå and Sundsvall. Further the material is spread out over two periods of time. More particularly five years before, and five years after the close down. We have employed a so-called synthetic week during both time intervals, meaning that you randomly select Monday one week, Tuesday the following week, and so forth. The result of the quantitative study showed that TT’s news reporting about the municipalities has decreased in all the aspects that have been investigated. The analysis of the result, together with previous research and chosen theories, indicates that TT seems to have become more commercialized and audience-oriented, which may have affected how news is valued. From a democratic perspective it is problematic. As the largest news agency TT plays an important role in Swedish journalism, not least when editorial offices around the country reduce their own news coverage.

Full textAbstract:
Den här uppsatsen har undersökt hur nyhetsbyrån TT rapporterat om flyktingar under två flyktingsituationer, åren 1992 och 2015. De frågeställningar som ska besvaras är: Finns det skillnader mellan hur TT 1992 skrev om flyktingar från f.d. Jugoslavien, och hur TT skriver om flyktingar 2015? Några delfrågor ska också besvaras: I vilka nyhetshändelser figurerar flyktingar och asylsökande? Får flyktingar eller asylsökande en talan i texterna? Är flyktingar eller asylsökande mer frekventa i positiva eller i negativa nyheter? Dessa frågeställningar har besvarats med hjälp av teorin om diskursiv diskriminering. Metoden som använts har varit en kvantitativ innehållsanalys, där urvalet var 130 st artiklar från 1992, och 203 st artiklar från 2015. Man kan se att TT:s medierapportering om flyktingar och asylsökande har varit skev och ojämn 1992, och fortsätter vara det 2015, i form av vem som får tala och vad själva nyheten handlar om. Man kan även se att medierapporteringen från 1992 och 2015 inte skiljer sig från varandra särskilt mycket, det finns dock skillnader. Nyhetshändelserna har skiftat fokus från brott mot flyktingar till flyktingpolitik. Flyktingar och asylsökande var frekventa subjekt i nyhetstexterna. Nyheterna som flyktingar eller asylsökande medverkar i är till stor del negativa, dock så har neutrala nyheter blivit mer vanliga.

Abstract
Safety assessment relating to the presence of impurities, residual materials and contaminants in vaccines is a focus area of research at the United States Food and Drug Administration (FDA). Sponsors who submit Investigational New Drug (IND) applications for new vaccine products must report the results of safety assessments to the Division of Vaccines and Related Products Applications (DVRPA). Scientifically defining thresholds of toxicological concern (TTCs) as they apply to vaccine constituents will provide a useful aid to the sponsors and public regarding safety assessments of compounds for which there is little or no toxicity data. TTCs are mathematically modeled and extrapolated levels, below which adverse human health effects are not expected to occur (Kroes, 2004). In this project, we accessed DVRPA's submission databases and open source data to yield an initial chemical test set. Using INCHEM, RepDose, RTECS and TOXNET, we gathered LD50 and TDLo data.
Using a structure-based decision tree, provided in the ToxTree software package, (3) different algorithms (The Cramer extended, the In vivo rodent micronucleus assay, and the Benigni-Bossa rule base for carcinogenicity by ISS) were applied to assign the initial test set (n= 197) of chemicals into structural families based on structural alerts (SAs). This resulted in six (6) potential methods for elucidating TTCs: In vivo rodent micronucleus assay/ LD50, Benigni-Bossa/ LD50, Cramer extended/ LD50, In vivo rodent micronucleus assay/ TDLo, Benigni-Bossa/ TDLo, and the Cramer extended/ TDLo.
After each algorithm designated two structural families each, the distribution of TDLo's and LD50's for each structural family was subjected to a preliminary data analysis using JMP statistical software version 9. Based on an analysis of quantiles, skew, and kurtosis, it was concluded that the TDLo dataset was of poor quality and was dropped from further analysis, and that the In vivo rodent micronucleus assay algorithm failed to partition the initial test set in a meaningful way, so it too was culled from further consideration. This resulted in (2) remaining TTC methods for further consideration: Benigni-Bossa/ LD50 and the Cramer extended/ LD50.
The remaining methods were subjected to internal validation based on Gene-Tox, CCRIS, CPDB, IARC, and EPA classaifications for genotoxic mutagenicity and carcinogenicity. Validation parameters were calculated for both methods and it was determined that the Benigni-Bossa/ LD50 method outperformed the Cramer extended/ LD50 method in terms of specificity (87.2 vs. 48.1%#37;), accuracy (65.2 vs. 52.94%#37;), positive predictivity (66.6 vs. 50%#37;), negative predictivity (64.8 vs. 56.5%#37;), ROC+ (2 vs. 1) and ROC- (1.84 vs. 1.3). These results indicated that the Benigni-Bossa/ LD50 was the most appropriate for calculating TTCs for vaccine constituents.
For each class, the lower 2.5th percentile LD50 was extrapolated to a TTC value using safety estimates derived using uncertainty factors (UF) and adjusting for adult human weight.

Full textAbstract:
This thesis has been conducted at the Swedish Defense Materiel Administration (FMV) on the department of mobile command center with supervised by ÅF. FMV Mobile Command centers main task is to integrate communication systems into Swedish Armed Forces (FM) vehicle systems. FMV has conducted a new radio system that will be integrated in FM. In communications systems various interfaces as mounting interface and connections interface frequent occurs. A mounting interface is an interface were the radio is mounted into a mounting frame or matching, connection interface is the cables and contacts or interfaces similar. During the procurement of the new radio system no requirements were written in the specification that it should fit in the existing mounting interface called mounting frame 42/48. Nor did the connection interfaces stated requirements in detail. The problem formulation of this thesis reads; How is it possible for FMV to work with integration of the new communications system in FM vehicles to create the best conditions, inside the boundaries that is given for this thesis? To get an understanding how integration can be better in FMV, questions were formulated from FMV, which are underlying the further work. A good foundation for the analysis are made from the feasibility on how a specification is written in FM, which laws that would have an effect for public authority and which methods and manuals that is available to aid. Interviews are then conducted with staff from FMV and with co-workers on the concept plant in Enköping, a lot of the tryouts of the new communication systems are done. Four different mounting system concepts on how the integrations can be done are evaluated and analyzed to get to a standing point. The conclusion from the analyze of the mounting frame concepts is that an updated version of the existing mounting frame could be the best. With the addition that the new acquired mounting frame also should have the potential to mount older radio systems. A mounting frame adjusts for the new radio system at the same time as the older fits. In this conclusion recommendations are presented on what FMV could work on to achieve better conditions for the integrations of communications systems. Conclusions that the start of a project is the most important factor, for the whole project to be made. The importance of the knowledge of a change late in a project is much more expensive than early in a project and the project participants have easier to get a clear picture if it is a good startup of a project. To find a common connection interface for the radio systems was not seen as a solution. Instead it is proposed to work with standards where it is possible and detail specifications where it is needed. ISRN UTH-

Full textAbstract:
The explosive growth of Internet-based architectures is allowing an efficient access to information resources over geographically dispersed areas. This fact is exerting a major influence on current manufacturing practices. Business activities involving customers, partners, employees and suppliers are being rapidly and efficiently integrated through networked information management environments. Therefore, efforts are required to take advantage of distributed infrastructures that can satisfy information integration and collaborative work strategies in corporate environments. In this research, Internet-based distributed solutions focused on the manufacturing industry are proposed. Three different systems have been developed for the tooling sector, specifically for the company Seco Tools UK Ltd (industrial collaborator). They are summarised as follows. SELTOOL is a Web-based open tool selection system involving the analysis of technical criteria to establish appropriate selection of inserts, toolholders and cutting data for turning, threading and grooving operations. It has been oriented to world-wide Seco customers. SELTOOL provides an interactive and crossed-way of searching for tooling parameters, rather than conventional representation schemes provided by catalogues. Mechanisms were developed to filter, convert and migrate data from different formats to the database (SQL-based) used by SELTOOL.TTS (Tool Trials System) is a Web-based system developed by the author and two other researchers to support Seco sales engineers and technical staff, who would perform tooling trials in geographically dispersed machining centres and benefit from sharing data and results generated by these tests. Through TTS tooling engineers (authorised users) can submit and retrieve highly specific technical tooling data for both milling and turning operations. Moreover, it is possible for tooling engineers to avoid the execution of new tool trials knowing the results of trials carried out in physically distant places, when another engineer had previously executed these trials. The system incorporates encrypted security features suitable for restricted use on the World Wide Web. An urgent need exists for tools to make sense of raw data, extracting useful knowledge from increasingly large collections of data now being constructed and made available from networked information environments. This explosive growth in the availability of information is overwhelming the capabilities of traditional information management systems, to provide efficient ways of detecting anomalies and significant patterns in large sets of data. Inexorably, the tooling industry is generating valuable experimental data. It is a potential and unexplored sector regarding the application of knowledge capturing systems. Hence, to address this issue, a knowledge discovery system called DISKOVER was developed. DISKOVER is an integrated Java-application consisting of five data mining modules, able to be operated through the Internet. Kluster and Q-Fast are two of these modules, entirely developed by the author. Fuzzy-K has been developed by the author in collaboration with another research student in the group at Durham. The final two modules (R-Set and MQG) have been developed by another member of the Durham group. To develop Kluster, a complete clustering methodology was proposed. Kluster is a clustering application able to combine the analysis of quantitative as well as categorical data (conceptual clustering) to establish data classification processes. This module incorporates two original contributions. Specifically, consistent indicators to measure the quality of the final classification and application of optimisation methods to the final groups obtained. Kluster provides the possibility, to users, of introducing case-studies to generate cutting parameters for particular Input requirements. Fuzzy-K is an application having the advantages of hierarchical clustering, while applying fuzzy membership functions to support the generation of similarity measures. The implementation of fuzzy membership functions helped to optimise the grouping of categorical data containing missing or imprecise values. As the tooling database is accessed through the Internet, which is a relatively slow access platform, it was decided to rely on faster Information retrieval mechanisms. Q-fast is an SQL-based exploratory data analysis (EDA) application, Implemented for this purpose.

Full textAbstract:
Software testing is one of the most important Software Engineering processes, being the primary activity to check the conformance between the software requirements and its actual behavior. The automation of software testing activities is essential to certify productivity and effectiveness in such activities. Test automation leads testing activities to be conducted under systematic and accurate criteria, raising the chance of testers to reveal faults or inconsistencies. Test oracles are elementary members in software testing automation, being the mechanism responsible for indicating the correctness of software outputs. In testing environments, test oracles can be effectively implemented based on several sources of information about the Software Under Testing (SUT): software specifications, assertions, formal methods (Finite State Machines (FSM), formal specifications, etc, machine-learning methods, and metamorphic relations. Regardless of the implementation strategy, test oracles are vulnerable to false positive/negative verdicts, configuring what the literature describes as the oracle problem. Therefore, test oracles are a non-trivial and challenging object of studies of the software engineering research area. SUTs outputs in unusual formats make it harder the oracle problem. Audio, images, three-dimensional objects, virtual reality environments, complex statistical compositions, etc, are examples of non-trivial output formats. In the software testing context, SUTs with unusual outputs can be called complex-output systems. In this doctorate dissertation, we propose and evaluate a novel test oracle approach for complex-output systems called feature-based test oracles. The purpose of feature-based test oracles is the appropriation of a processing image technique called Content-Based Image Retrieval (CBIR) to collect information from features extracted from the SUTs outputs to compose test oracles. Given a query image, CBIR combines feature extraction and similarity functions to alleviate the problem of searching for digital images in large databases. In previous research, we have integrated CBIR concepts in a testing framework to support the automation of testing activities in processing image systems and systems with Graphical User Interfaces (GUI). In this doctorate dissertation, we extended that framework and its concepts to general complex-output systems, addressing the feature-based test oracle approach. We use Text-To-Speech (TTS) systems to validate empirically our test oracle technique. Through the results of five empirical analyses, three of them conducted in line with problems of a real-world industry TTS system, show the proposed technique is a valuable instrument to automate testing activities and alleviate practitioners efforts on testing complex output systems. We conclude the proposed test oracles are effective because they systematically evaluate the SUTs sensorial output rather than produce verdicts based on subjective specifications. As future work, we plan to conduct investigations towards the reduction of false positives/negatives and the association of the test oracles with machine learning techniques and metamorphic relations.<br>Teste de Software é um dos processos mais importantes da Engenharia de Software, sendo a principal atividade para averiguar a conformidade de requisitos de software e suas saídas. A automatização das atividades de teste é essencial para conferir produtividade e efetividade em tais atividades. A automatização faz com que atividades de teste sejam conduzidas sob critérios sistemáticos e precisos, aumentando a chance dos testadores de revelarem falhas ou inconcistências. Oráculos de teste são membros elementares na automatização do teste de software, sendo o mecanismo responsável por indicar a corretude das saídas do softwre. Em ambientes de teste, oráculos de teste podem ser efetivamente implementados com base em diversos fontes de informação sobre o sistema em teste: especificações de software, assertivas, métodos formais (máquinas de estados finitas, especificações formais, etc), métodos de aprendizagem de máquina e relações metamórficas. Independente da estratégia de implementação, oráculos de teste são vulneráveis a veridictos de falsos positivos/negativos, configurando o que é apresentado na literatura como O problema do Oráculo. Então, na área de engenharia de software, oráculos de teste são objetos de estudo não-triviais e desafiadores. O problema de oráculo é potencializado quando as saídas do sistema em teste são dadas em formatos não triviais como, por exemplo, audio, imagens, objetos tridimensionais, ambientes de realidade virtual, composições estatísticas complexas, etc. No contexto do teste de software, sistemas com saídas não triviais podem ser chamados de sistemas com saídas complexas. Esta tese de doutorado propões e avalia uma nova estratégia de oráculo de teste para sistemas com saídas complexas. O propósito de tal estratégia é a apropriação da técnica de processamento de imagem conhecida como CBIR (Recuperação de Imagem Basead em Conteúdo CBIR) para coletar informações de características extratídas do sistema em teste, compondo oráculos de teste. A partir de uma imagem de busca, o CBIR combina extração de características e funções de similaridade para aliviar problemas de busca em grandes based de imagens digitais. Em pesquisas anteriores, conceitos de CBIR foram integrados em um arcabouço de teste para apoiar a automatização de atividades de teste em systemas de processamento de imagens e sistemas com interfaces gráficas. Esta tese de doutorado estende o arcabouço e seus conceitos para sistemas com saídas complexas em geral. Sistemas Texto-Fala (TTS) foram utlizados para validações empíricas. Os resultados de seis análises empíricas, duas delas condizidas em consonância com problemas de um TTS industrial, revelam que a técnica proposta é um valioso instrumento para automatizar atividaes de teste e aliviar esforços de profissionais da indústria ao teste sistemas com saídas complexas. Conclui-se que a efetividade dos oráculos de teste propostos são devido às sistemáticas análises do conteúdo das saídas dos sistemas em teste, em vez da análises de especificações subjetivas. Os trabalhos futuros vislumbrados devem ser conduzidos no intuito de reduzir número de falsos positivos/negativos e a associação dos oráculos de teste com técnicas de aprendizado de máquina e relações metamórficas.

碩士<br>國立臺灣大學<br>食品科技研究所<br>104<br>Obesity is a critical issue worldwide. According to Nutrition and Health Survey in 2013 indicated that prevalence of overweight and obesity was 38% in Taiwan people. And World Health Organization (WHO) indicate that compare to the normal weight people the obesity people have higher risk of chronic disease which include diabetes mellitus, dyslipidemia, hepatic steatosis and hypertension. The concept of drinking tea is for a long time and widely accepted. However, the strain of Andraca theae which lives on tea leaf and its metabolites called the tea metabolites from Andraca theae that bioactivity is unknown yet. Consequently, this study was aimed to investigate whether extract of TTES No.12 and its metabolites from Andraca theae (TME) have the same or better effect than TTES No.12 tea extract (TE) on prevention of obesity and obesity-induced chronical disease. The animal model used high fat diet and different dose of TME and TE for a period of time. After administrated TME improved serum total cholesterol parameters. However, after administrated TE, our results showed that TE significantly decreased all adipose tissue and adipocyte size via increasing Pref-1and inhibiting downstream signaling pathway. However, TE also significantly improved fatty hepatocytes via increasing Ho-1. Taken together, these results suggested that the content of tea polyphenols play an important role for the prevention of obesity and fatty liver disease.

Full textAbstract:
碩士<br>元培醫事科技大學<br>生物科技暨製藥技術系碩士班<br>104<br>Teas contained abundant polyphenolic compounds. Previous researches have demonstrated that polyphenolic compounds physiologically play critical roles as antioxidant, antibacterial, anti-inflammatory, inhibiting melanin production and in many functions for skin health. Tea extracts can be very beneficial for human skin care. Effects of extracts from various Taiwan teas on skin care and skin cancer antiproliferation effects were investigated in this study. Green tea and black tea samples were processed from 4 Taiwan Tea varieties (TTES No. 8, 12 , 18, 21), and those tea extracts were analyzed to determine polyphenols composition, antioxidant activity, tyrosinase inhibitory activity, and melanin inhibition of melanoma cells (B16-10). Cell viability of keratinocytes (HaCaT) was assessed by MTT assay to evaluate protection against UVB radiation, and anti-proliferative effect on human epidermoid carcinoma cells (A-431).
Results indicated that green tea from large-leafed variety (TTES No. 8, 18, 21) exhibited higher levels of antioxidant activity, reducing power and antiproliferation activity on skin cancer cell line (A-431), better than those of the same varities of tea extracts obtained from black tea products. Our results showed that these effects related with high levels of total phenolics and catechins. Among all tested samples, large-leafed variety TTES No.21 green tea exhibited the highest inhibition activities. Cell cycle analysis demonstrated that large-leafed TTES No.21 green tea extract can suppress human epidermoid carcinoma cells (A-431). The signaling pathways of G0/G1 phase was malfunction and further blocked S phase and G2-M phase leading to cell numbers increased in S phase and G2-M phase and not able to go through normal cell division. Eventually those cells went through apoptosis. However, for the inhibition of tyrosinase activity, inhibitions of melanoma cells to produce melanin ability and anti-UVB effect on keratinocytes were significantly higher in black tea compared with those of green tea. For skin care activity of black tea, not only catechins, theaflavins and thearubigins, and other active polymerized polyphenol compounds also might be contributed function. These findings suggested that TTES No. 18 and 21 are not easily to be processed to famous tea products like "Ruby" and "Hong Yun" as popular summer tea, however, winter tea can still be utilized to produce green tea products for antioxidant and anti-skin cancer, and black tea can serve as cosmetic whitening and anti-UVB radiation skin care product. Therefore, large-leafed variety winter tea products have potential for developing novel skin care products and further adding agricultural value for winter tea products.

The purpose of this study were to investigate the TTES No. 18 black tea plant growth responses under different tillage systems and combined with application of different water absorbent dosages and impact on soil nutrient elements in order to find the best application combination of cultural system and water absorbent treatments dosage. The results can improve the quality of tea, water-saving on irrigation and less amount of fertilizer applications.
Two different cultivation methods (sod culture and clean cultivation) as well as different amount of water absorbent agent (0,125,250 and 375 g g/5.04m2) treatment combinations were tested. The test results showed that: application of water absorbent treatment increased number of tea buds,promote leaves length, leaf width and leaf area growth. The bud leaf length under 125 g/5.04m2 water absorbent treatment increased 0.44 cm, the first leaf width and leaf area increased (0.16 cm and 1.03 cm2) under 375 g /5.04m2 treatment. The second leaf length increased 0.81 cm under 250 g/5.04m2 treatment. The second leaf width and leaf area increased (0.35 cm and 2.93 cm2) under 375 g/5.04m2. Shoots fresh weight increased 162.5 g under 125 g/5.04m2 treatment. Sod cultivation significantly increased fresh weight of bud 245.31 g/5.04m2 as compared to the clean cultivation.
Although there is no significant differences on the remaining afronomic traits, but applying water absorbent all showed better performances.
It is recommended to apply 375 g/5. 04m2 water absorbent implement in sod cultivation of tea plantation, thus can improve the production of tea and effectively maintain higher nutrient content in the soil.

Full textAbstract:
碩士<br>國立臺灣大學<br>園藝暨景觀學系<br>106<br>Tea plants (Camellia sinenesis L.) are leafy plants. During producing process, nitrogen giving is concerned. Over-fertilization nitrogen in ground would threat economy other than low rate of nitrogen usage. Using foliar fertilization as partial nitrogen resource might be a solution to overcome the disadvantages. Main purposes of this research are to look into how foliar application effect on tea plant (Camellia sinensis L.) growth and tea quality related content in new-born flush. Foliar application or ground application at timing combination and urea dosage are two treatment factor.
In first experiment, ‘TTES 12’ tea plants were treated in 2017. ‘After cutting’, ‘fish leaf extend’, ‘two true leaf extend’ are three fertilization timings. Timing combinations are treatments that choose none, one, two and three fertilization timings for nitrogen foliar application and the others for ground nitrogen application. Taking urea as nitrogen source, dosage differentiates are operated by 0.5% 8ml urea solution applying once or 0.5% 8 ml urea solution applying twice, five days as time interval. At 60th days after cutting, whole new-born flushes were investigated and analyzed. Investigated item include length, number of extend leaf of new-born flush and number of emerge flush. Analysis items include total amino acid, total polyphenol and total nitrogen.
In 2017 spring trail, more average new-born flush length was showed in double dosage treatments. When concerning about foliar application times effect, choosing two timing and three timing for foliar fertilization are statistically no difference in average new-born flush length. But they still statistically higher than none foliar fertilization and foliar fertilization once. Multiple linear regression are used to analyze effect of ground fertilization and foliar fertilization at timings. Result shows that fertilizing at ‘fish leaf extend’ doesn’t help growing of new-born flush.
In 2017 summer trail, ‘fish leaf extend’ timing was excluded, another detail that way of treatments and investigate items are as spring trail. Collected new-born flushes are separated into one bud with two leaves and below part for content analysis. Repeated trail was practiced in 2018 spring again for comparing seasonal discrepancy.
General speaking, growth potential of tea plant in spring is weak. At the trial end, new-born flushes are all at ‘banjhi’ stage. Total nitrogen content is lower than summer sample, but total polyphenol concentration is as much as that in one bud with two leaves part in summer trail. Except for total amino acid concentration, samples for double dosage treatment have nearly twice as much as summer ones. According to multiple linear regression, amount of ground nitrogen fertilization at ‘after cutting’ and ‘two true leaves extend’ can be used to predict amount of total nitrogen in spring new-born flush.
In summer trail, growth potential of tea plants are high. At the trial end, new-born flushes are all at ‘growing’ stage. Almost 50% content concentrated in part of one bud with two leaves, but it didn’t happen to excess accumulation. According to multiple linear regression, foliar or ground fertilize at ‘two true leaves extend’ both can be used to predict amount of total nitrogen in summer new-born flush, but amount of nitrogen from foliar fertilization at this timing have higher correlation to it.
Another experiment explore that how leaves absorb and metabolism urea after urea foliar application. Tea plants with several new-born flush are treated urea solution for whole plant. Treatments are 1% urea solution applying once and 0.5% urea solution applying twice, 128 hours as time interval. Sampling at before urea spray, 1, 2, 4, 8, 16, 32, 64, 128 hours after urea spray, urea concentration in tea leaves of new-born flush are analyzed. Urea foliar application can make urea concentration increase in mature leaves. 1% urea solution treatment have higher instant cumulate than 0.5% urea solution treatment in one hour. Then they will reach stable leaf-urea-accumulating limit and decrease in similar variation trend. And both back to before-treated level after 128 hours. Continuing sampling for 0.5% urea solution treatment, second-time 0.5% urea spray make similar variation trend as the first time spraying. When 32 hours after second-time 0.5% urea spray, it has been in a downward trend. As a result, 0.5% urea solution and five days at least as time interval is more suitable for tea plant to urea foliar fertilize.

碩士<br>國立臺灣大學<br>農業化學系研究所<br>86<br>As the uplifting of living standard in Taiwan, the consumption of tea is in
creasing in recent years. More and more customers expect for buying organic t
ea because of concerning about their own health. In organic farming system, fa
rmers use organic fertilizer instead of chemical fertilizer to protect the env
ironment and to maintain the ecosystem balance. However, we don''t know much a
bout the effect of tea plants growing on different organic fertilizer. The eff
ects of pea-rice hull compost and hog dung manure in acid red soil and calcare
ous soil on the growth and nutrient uptake of TTES No.12 and Chin-shin Oolong
were studied in this study. Besides, an incubation experiment was set to see t
he decomposition and nutrient releasing of the two organic fertilizers in the
two soils. In the pot experiment, two organic fertilizers, two soils, and two
kinds of tea cultivar were used and chemical fertilizer was as check treatment
. There were twelve treatments and each treatment was replicated six times and
arranged in randomized completely block design. The tea plants and soil sampl
es were sampled after nine months planting. The tea plants were separated into
root, stem and leaf and the nitrogen composition, and the concentration of ph
osphorous, potassium, calcium, magnesium, iron, aluminum, and manganese were a
nalyzed. The pH, electric conductivity of saturation extract, the concentratio
n of nitrate nitrogen, ammonium nitrogen and Bray No. 1 extractable P of soils
were also determined. There were sixteen treatments and every treatment was r
eplicatedthree times in the incubation experiment. The soils were sampled ever
y ten days and were analyzed pH, electric conductivity of saturation extract,
the concentration of nitrate nitrogen and ammonium nitrogen.In the pot experim
ent, TTES No.12 that grew in red soil and applied with hog dung manure had the
highestproduction and absorbed most nitrogen among the treatments. The tea pl
ants grew better in red soil than in calcareous soil and TTES No.12 grew bette
r thanChin-shin Oolong. The nitrogen concentration of the tea plants growing i
n redsoil was higher than that in calcareous soil. Both nitrate nitrogen and a
mmonium nitrogen concentration in the tea plants was low. Insoluble nitrogen w
as the major portion of nitrogen and the insoluble nitrogen concentration of t
he tea plants growing in red soil was higher than that in calcareous soil. The
trend of total soluble reduced nitrogen and soluble organic nitrogen concentr
ationon was similar. In acid red soil, the tea plants absorbed more phosphorou
s and the concentration were higher in organic fertilizer treatment than that
in chemicalfertilizer treatment. The concentration of potassium was also highe
r in red soil and affected by the concentration of calcium in the tea plants.
In red soil,the hog dung manure treated plant had the highest calcium concentr
ation but that in calcareous soil was higher than in red soil. The magnesium c
oncentrationwas higher in organic fertilizer treatment than that in chemical f
ertilizertreatment. The aluminum concentration of the tea plants growing in re
d soil was significantly higher and that in TTES No. 12.The aluminum concentra
tion in TTES No. 12 was higher than that in Chin-shin Oolong.Most aluminum wa
s concentrated in roots and iron, too. The manganeseconcentration of the tea p
lants growing in red soil was higher than that inother parts. The absorption o
f aluminum and manganese was also affected by calcium in the growth medium. In
the incubation experiment, the soil pH was increasing slowly at the beginning
and then decreasing. Soil with higher application rate of organic fertilizer
and higher water content had higher electric conductivity of saturation extra
ct. In red soil, the electric conductivity of saturation extract of hog dung m
anure treatmentwas higher than that of pea-rice hull compost treatment but the
reverse was true in calcareous soil. The ammonium nitrogen concentration in b
oth soils was low and decreasing by time. The nitrate nitrogen concentration i
n both soils was increasing by time and the application rate of fertilizers. T
he nitrate concentration in calcareous soil was higher than that in the red so
il.

Unlike the ordinary discrete logarithm problem, the integer factorization problem, and the elliptic curve discrete logarithm problem which take lots of big number
modulo and exponential operations and thus are very time-consuming, TTM operates in a much higher speed.
However, since generating and verifying signatures is one of the most important applications of a public key cryptosystem, Chen et al. proposed TTS (Tame Transformation Signatures), a signature version of TTM, in IWAP

碩士<br>國立雲林科技大學<br>企業管理系<br>106<br>In the age of rapid globalization, what is the role of continuing education in Taiwan’s universities? What is the impact of TTQS on the performance of continuing education? The paper explores the influence of TTQS on the quality and business performance of universities. We also try to understand why many universities are not interested in pursuing the golden medal of TTQS. This paper uses questionnaire to collect research samples. With respect to those universities who got at least bronze medal of TTQS, we sent out total 98 questionnaires. Finally, we got 50 effective samples with 51% returning rate.
Based on the literature review and survey theory, we designed our questionnaire. After getting the samples, we did first the basic statistical analysis and then the one-factor variance analysis in many aspects. Finally, we use multiple regressions to explore two issues. For whether TTQS would affect the performance of continuing education, we find that (1) TTOS would raise the quality of training and (2) TTQS would increase the number of training courses. For the factors of driving the universities to pursuing TTQS Golden medal, we find that: (1) supporting from the leaders of the universities is a key. (2) The efforts of the staff are also a key to decide whether an institute can win the medal.

碩士<br>國立虎尾科技大學<br>資訊管理研究所<br>102<br>Although many scholars pay more attention on employees’ competence, propose assessment methods likes employee training, training course, training method, training result, and suggest enterprise planning training course or educate internal trainer. However, because training course doesn''t meet enterprise requires, and mechanism can''t keep assessing, evaluating, improving, making the low efficiency on information literacy improvement. The main reason is that enterprise lacking of systematized information system, so can''t check each employee''s ability, and it needs course.
Hence, this research reviews previous literature, to understand the framework of Taiwan TrainQuali System. Then, through qualitative interview methods, this research captures the consensus among experts, to combines the 2 TTQS versions: Version for Business Institution and Version for Professional Training Institution, then systemize 19 main indicators and scaling indices. So, this research can establish TTQS information system structure, which not only meets the spirit and process of TTQS, but fits all main indicators and scaling indices. These research results can assist enterprises or organizations to follow PDDRO cycle, then improve competence training quality.

Supernovae are fundamental in astronomy: they inject high mass elements into the interstellar medium enriching the chemistry of galaxies, they feed processes of star formation and active galactic nuclei, and they have been a key for the developments in cosmology of the past decades.
This dissertation presents a set of subluminous type Ia supernovae (SNe Ia) at z>0.1 from the Supernova Legacy Survey (SNLS). These faint and short-lived transients are found in massive and passive host galaxies. We measure a volumetric rate as a function of redshift that is different from the normal SNIa population. The observations point towards a long delay time since the birth of the progenitors systems and argue for progenitor stars of initial low mass.
We calculate a stretch-corrected rise-time since explosion to maximum brightness for different sets of SNe~Ia. We find that a fiducial 17 day quadratic rise is sufficient to explain all SNe Ia, including subluminous ones, arguing for their homogeneity throughout the entire light-curve. Subluminous SNe Ia are powered by as little as 0.05 solar masses of radioactive nickel synthesized in the explosion. Theoretical models need to explain these challenging weak explosions within the framework of SNe Ia.
Finally, we develop one of the first robust automated techniques to identify plateau supernovae (SNe IIP) in large photometric transient surveys. This simple method was tested with a variety of real and simulated SN samples and proved to be effective across different redshifts. Such a photometric typing will be of great power for coming surveys and will allow numerous scientific studies of SNe IIP.

碩士<br>實踐大學<br>企業管理學系碩士班<br>99<br>The research investigates the general satisfaction and survey from professional who have trained in the TTQS (Taiwan Train Quality System). These questionnaires offer for three kinds of 457 professional staffs. (The professional staffs have a total assessment committee of 200 members in 2010 of this year. There are 139 counselors and 118 trainers.) The research found that the entire system of TTQS and each service center, which offers quality of service, is generally satisfied of professional staffs; in addition, the SOP (standard operate process) should abide by the provisions of the rights and obligations has also shown a high degree of satisfaction level. Finally, studies have also learned that more than 90% of the three categories are considered to create an exit mechanism for the officials deemed to be incompetent. According to this situation, the research makes some suggestions:
1. More than 90 percent of the three types considered to create an exit mechanism for the officials deemed to be incompetent. The different identity will affect the cognition of ideal exit mechanism; the assessment committee members and counselors regarded that the ethical norms will be the perfect exit mechanism; the educational trainers think that the student satisfaction is optimum exit mechanism. As a result, most of professional believe that the exit mechanism can enhance the over level of exit, so it recommendations TTQS exchange control units can follow-up that to be proceed with the direction.
2. Up to 93 percent members of the assessment considered that the district service center sends (connection) number of cases is really reasonable this year. The point also represents the year for exchange control units and the district service center have received as the largest result. It improved the past of problems for the case system; moreover, it more confirmed the fairness and practicality since start using the system of automatically sent the case. After that, when they follow this system, it reduce the injustice situation.

In this thesis, a corpus-based Mandarin Text-to-Speech system is implemented. Besides integrating the present text analyzer and the prosodic information generator, the study emphasizes on designing a unit-selection algorithm to solve the two main problems of searching all possible synthesis unit candidates in a huge corpus efficiently and selecting an appropriate unit sequence. We improve the efficiency of the continuous-correlative comparison method without decreasing the quality of the synthesis waveforms. Also we re-define the cost function used in the unit selection.
Finally, for users’ convenience, we design a graphical user interface for this system. The user can directly type his input text, and get the synthesis waveform and some intermediate information automatically.

Full textAbstract:
碩士<br>國立成功大學<br>資訊工程研究所<br>88<br>In this thesis, two of the most commonly used languages in Taiwan (Taiwanese and Mandarin) are analyzed and the results are used to build modules of Mandarin—Taiwanese Machine Translation (MT) System. In order to provide the MT System a learning function, a system called ”Myna” is proposed. It has four units：
First, Bilingual Dictionary/Modification Unit—modifying bilingual dictionary online.
Second, Phonetic Alphabet Setup Unit — Set up the Taiwanese spelling words according to user’s habit.
Third, Balanced Sentences and Synthesis Syllable Collection Unit — Collects the balanced Taiwanese sentences and provides Taiwanese Synthesis Syllables.
Fourth, Interactive Learning Unit — This unit enables users to modify the translations and add new words to the dictionary.
Based on Myna development system, a Mandarin-Taiwanese MT prototype system is created. We can find the correct rate of sentence translation in Mandarin — Taiwanese MT prototype system base on Myna comes from 63.4% and 62.1% to 75.6% and 74.7%. And also because of the improvement of correct rate of sentence translation, the mean opinion scores (MOS) and the recognizable rate have a great improvement on TTS system. Myna system provides the MT prototype system a learning module; meanwhile, it greatly improves the efficiency in MT prototype systems.
