Texto completoNumerous optimization problems involve systems with multiple and often contradictory criteria. Such contradictory criteria have been an issue for marine/naval engineering design studies for many years. This problem becomes more important when one considers novel ship types with very limited or no operational record. A number of approaches have been proposed to overcome these multiple criteria design optimization problems. This Thesis follows the Parameter Space Investigation (PSI) technique to address these problems. The PSI method is implemented with a software package called MOVI (Multi-criteria Optimization and Vector Identification). Two marine/naval engineering design optimization models were investigated using the PSI technique along with the MOVI software. The first example was a bulk carrier design model which was previously studied with other optimization methods. This model, which was selected due to its relatively small dimensionality and the availability of existing studies, was utilized in order to demonstrate and validate the features of the proposed approach. A more realistic example was based on the "MIT Functional Ship Design Synthesis Model" with a greater number of parameters, criteria, and functional constraints. A series of optimization studies conducted for this model demonstrated that the proposed approach can be implemented in a naval ship design environment and can lead to a large design parameter space exploration with minimum computational effort.

Texto completo- Screening: Reduce a large set of alternatives to a smaller set that most likely contains the best choice.
- Sorting: Arrange the alternatives into a few groups in preference order, so that the DM can manage them more effectively.
- Nominal classification: Assign alternatives to nominal groups structured by the DM, so that the number of groups, and the characteristics of each group, seem appropriate to the DM.
Sorting problems are studied extensively under three headings. Case-based distance sorting is carried out with Model I, which is optimized for use with cardinal criteria only, and Model II, which is designed for both cardinal and ordinal criteria; both sorting approaches are applied to a case study in Canadian municipal water usage analysis. Sorting in inventory management is studied using a case-based distance method designed for multiple criteria ABC analysis, and then applied to a case study involving hospital inventory management. Finally sorting is applied to bilateral negotiation using a case-based distance model to assist negotiators that is then demonstrated on a negotiation regarding the supply of bicycle components.
A new kind of decision analysis problem, called multiple criteria nominal classification (MCNC), is addressed. Traditional classification methods in MCDA focus on sorting alternatives into groups ordered by preference. MCNC is the classification of alternatives into nominal groups, structured by the DM, who specifies multiple characteristics for each group. The features, definitions and structures of MCNC are presented, emphasizing criterion and alternative flexibility. An analysis procedure is proposed to solve MCNC problems systematically and applied to a water resources planning problem.

Texto completoNegli ultimi vent'anni l'interesse per le macchine sincrone a riluttanza è notevolmente cresciuto. Lo sviluppo e la ricerca dedicata a questi motori, supportata dai diversi vantaggi che presentano rispetto ad altri tipi di macchine, ha permesso a questa tipologia di macchina di guadagnarsi uno quota di mercato in diverse applicazioni industriali. I motori a riluttanza offrono una piu alta densità di coppia rispetto ai motori asincroni. Tuttavia, se confrontati con i motori sincroni a magneti permanenti, essi presentano una densità di coppia ed una efficenza minori. Tale decremento delle prestazioni rispetto alle macchine a magneti permanenti è tuttavia compensato dalla complessiva riduzione del costo di costruzione del rotore. In aggiunta, essi presentano una struttura rotorica piu robusta delle macchine sincrone a magneti superficiali e consentono di ottenere un piu ampio range di funzionamento a potenza costante. I principali svantaggi delle macchine sincrone a riluttanza sono il basso fattore di potenza e le elevate oscillazioni di coppia. Il primo svantaggio, correlato alla assenza di alcun sistema di eccitazione sul rotore, viene normalmente mitigato attraverso l'introduzione di magneti permanenti all'interno delle barriere di flusso. Questo tipo di configurazione prende il nome di motore a riluttanza assistita da magnete permanente. Il secondo svantaggio, ossia l'eccessivo torque ripple, è dovuto all'elevato contenuto armonico della forza magnetomotrice che interagisce con l'anisotropia rotorica. Diversi approcci sono stati proposti in letteratura allo scopo di ridurre tali oscillazioni, tra i quali: (a) lo skewing del rotore, (b) barriere rotoriche geometricamente asimmetriche rispetto all'asse interpolare, (c) barriere rotoriche asimmetriche rispetto all'asse polare, (d) equa distribuzione delle barriere lungo la periferia del rotore, e (e) l'ottimizzazione della intera geometria delle barriere. Il grande interesse suscitato negli ultimi anni è dovuto principalmente a due motivi: (i) l'aumento di costo delle terre rare, utilizzate in magneti ad elevato contenuto energetico (NdFeB e SmCo); (ii) la crescente richiesta di macchine ad alta efficienza. Pertanto, il motore a riluttanza e il motore a riluttanza assistito da magneti permanenti stanno diventando concorrenti di entrambe le macchine a magneti permanenti e macchine a asincrone in molte applicazioni. Un altro vantaggio intrinseco delle macchine sincrone a riluttanza è che non inducono tensione a vuoto, quando il rotore è fermo, conseguentemente le correnti di corto circuito e coppie frenanti che si possono creare a causa dei guasti elettrici, sono trascurabili. Per quanto concerne l'aspetto controllistico è doveroso sottolineare il crescente interesse verso le le macchine sicrone a riluttanza. Tale interesse è sostanzialmente giustificato dalla naturale propensione della stessa macchina ad essere controllata senza alcun sensore di velocità. Sebbene vi sia un grande interesse per questo tipo di macchine, ci sono pochi lavori sulla progettazione analitica del loro rotore, ad esempio su come selezionare gli angoli di fine barriera, il dimensionamento dei ponticelli di ferro ed dettagli sulla progettazione robusta nei confronti della smagnetizzazione dei magneti permanenti. Nella maggior parte dei casi la macchina riluttanza viene analizzata mediante analisi agli elementi finiti. I risultati sono precisi e utili per realizzare una geometria specifica, ma si riferiscono ad una particolare soluzione perdendo generalità. In altre parole, è difficile trovare regole generali per progettare macchine a riluttanza. Per colmare questa lacuna, questa tesi si propone di fornire un approccio analitico utile alla determinazione di una geometria preliminare del motore, come punto di partenza per un'ottimizzazione successiva. La progettazione accurata dei ponticelli di ferro del rotore e gli effetti sulla forza elettromagnetica che agisce sul rotore con diversi gradi di eccentricità sono considerati. Questo lavoro di tesi è suddiviso in quattro parti principali. Un modello analitico basato sul circuito magnetico equivalente a parametri concentrati del motore a riluttanza viene presentato e discusso nella prima parte. Questo modello studia il rendimento magnetico del motore sincrono a riluttanza concentrica. Lo stesso modello analitico è utilizzato per lo studio di differenti casi di eccentricità ed il loro impatto sulle prestazioni del motore a riluttanza. Motori a riluttanza con diversi tipi di avvolgimenti statici e diverse geometrie di rotore, simmetriche ed asimmetriche, vengono considerate. Lo stesso metodo viene applicato a motori a riluttanza con magneti permanenti e confrontata con il motore a riluttanza eccentrico. I risultati prodotti dai modelli utilizzati vensono confrontati tramie simulazioni agli elementi finiti. Inoltre, un confronto analitico tra il motore a riluttanza e motore a magneti permanenti superficiali viene condotta in diversi casi di eccentricità. La seconda parte si propone di stimare in modo più accurato le forze elettromagnetiche agenti sul rotore, considerando l'effetto delle cave di statore e la caduta di tensione magnetica dovuta alla effettiva curva B-H del lamierino ferromagnetico. Il modello analitico è indicato per macchine con e senza presenza di eccentricità. Infine, misure sperimentali vengono condotte per validare la bonta' dei modelli analitici ed agli elementi finiti. Nella terza parte, si propone un approccio analitico per la progettazione del motore a riluttanza assistito da magneti permanenti. La larghezza e lo spessore dei magneti sono scelti in modo da realizzare la densità di flusso a vuoto al trafetto desiderata e resistere alla smagnetizzazione che si possono presentare in condizioni di sovraccarico. Infine, un rapido approccio analitico e multi-obiettivo è proposto per la progettazione preliminare di motori a riluttanza e motori a riluttanza assistiti. Nella quarta parte è stata sviluppata un'interfaccia utente grafica per l'analisi del motore a riluttanza. Questa applicazione stima i potenziali scalari magnetici di statore e rotore, la densità di flusso al traferro, la coppia elettromagnetica, la forza magnetica che agisce sul rotore. I parametri di ingresso di questa applicazione sono: - dati geometrici dello statore e del rotore, - carico elettrico (kA / m), e la sua fase (grado elettrico), - il tipo di geometria del rotore, ad esempio, simmetrico o asimmetrico (Macaone), - Numero di barriere di flusso per polo del rotore, - il tipo di eccentricità o nessuna eccentricità, per esempio, il caso con rotore concentrico, - il valore di eccentricità. Perciò, l'utente può usare l'applicazione per stimare le prestazioni della macchina.

Texto completoThe pearl oyster Pinctada martensii or Pinctada fucata is the oyster for produce the South China Sea Pearl, and the production of pearl oyster Pinctada martensii plays a key role for the economic and social welfare of the coastal areas. To guarantee both rich and sustainability of providing pearl oyster productions, addressing the suitable areas for aquaculture is a very important consideration in any aquaculture activities. Relatively rarely, in the case of site selection research, the researchers use GIS analysis to identify suitable sites in fishery industry in China. Therefore, I decided to help the local government to search suitable sites form the view of GIS context. This study was conducted to find the optimal sites for suspended culture of pearl oyster Pinctada martensii using GIS-based multi-criteria analysis. The original idea came from the research of Radiarta and his colleagues in 2008 in Japan. Most of the parameters in the GIS model were extracted from remote sensing data (Moderate Resolution Imaging Spectroradiometer and Landsat 7). Eleven thematic layers were arranged into three sub-models, namely: biophysical model, social-economic model and constraint model. The biophysical model includes sea surface temperature, chlorophyll-α concentration, suspended sediment concentration and bathymetry. The criteria in the social-economic model are distance to cities and towns and distance to piers. The constraint model was used to exclude the places from the research area where the natural conditions cannot be fulfilled for the development of pearl oyster aquaculture; it contains river mouth, tourism area, harbor, salt fields / shrimp ponds, and non-related water area. Finally those GIS sub-models were used to address the optimal sites for pearl oyster Pinctada martensii culture by using weighted linear combination evaluation. In the final result, suitability levels were arranged from 1 (least suitable) to 8 (most suitable), and about 2.4% of the total potential area had the higher levels (level 6 and 7). These areas were considered to be the places that have the most suitable conditions for pearl oyster Pinctada martensii for costal water of Yingpan.

Texto completoDiplomityö pyrkii konstruktiivisen tutkimuksen avulla soveltamaan monikriteerisiä päätösanalyysiteorioita (Multi Criteria Decision Analysis — MCDA) kiinteistöportfoliohallinnan päätöksentekoon. Teorioita sovelletaan työssä kehittämällä kiinteistöportfoliohallinnan päätöksentekoa avustava malli. MCDA on oppi metodeista ja lähestymistavoista, joissa eri vaihtoehtojen paremmuutta arvioidaan suhteessa päätöksentekijän asettamiin tavoitteisiin. Teorioiden käsittelemien päätösongelmien luonteeseen kuuluvat useat ristiriitaiset ja yhteismitattomat kriteerit, jotka tekevät päätöksenteosta erittäin haasteellista. MCDA:n tuoma arvo päätöksentekoon syntyy sen jäsennellystä ja selkeästä tavasta käsitellä päätösongelmaa, minkä johdosta päätöksentekijä tulee tietoisemmaksi itse päätösongelmasta sekä omista ja muiden sidosryhmien arvoista ja tavoitteista. Monikriteerisiä päätösanalyysiteorioita on sovellettu aiemmin esimerkiksi infrapuolella siltojen kunnossapitoprojektien valintaan. Kehitetyn matemaattisen mallin avulla pystyttiin analyyttisesti arvioimaan kunkin vaihtoehdon hyvyyttä ja poimimaan siltakannasta eniten päätöksentekijän tavoitteita vastaavat kohteet. Tutkimus toteutettiin kolmessa osiossa, joista ensimmäisessä selvitettiin MCDA:n perusteet määrittämällä kirjallisuuskatsauksen avulla päätöksentekijän preferenssejä mallintava MAVT-prosessi. Kirjallisuuskatsauksen jälkeen seurasi työn empiirinen osio, mikä pyrki haastatteluiden avulla selvittämään kiinteistöportfoliohallinnan päätöksentekoa ohjaavat kriteerit ja niiden toteutumista mittaavat attribuutit. Työ keskittyi käsittelemään vain kiinteistökohtaisten sisäsyntyisten tekijöiden vaikutusta kiinteistöportfoliohallintaan. Lopuksi empiriasta saatujen tuloksien pohjalta kuvattiin MAVT prosessi kyseessä olevassa kontekstissa ja kehitettiin esimerkkimalli kiinteistöportfoliohallinnan päätöksenteon tueksi. Esitetty malli on suunnattu yksityisille kiinteistönomistajille, jotka omistavat liike- ja toimistokiinteistöjä vain sijoitusmielessä. Tutkimuksen tuloksena saatiin viisi kiinteistöportfoliohallinnan päätöksentekoa ohjaavaa kriteeriä: makrosijainti, mikrosijainti, sopimushinta, kiinteistön korjaustarpeet ja kiinteistön kehittymiskyky. Sijainti kriteerit pyrkivät huomioimaan sekä makroympäristön kehittymisen että kiinteistön saavutettavuuden. Sopimushinta ja kiinteistön korjaustarpeet puolestaan kuvaavat kiinteistön kassavirran negatiivisen ja positiivisen puolen tärkeimpiä tekijöitä. Kiinteistön kehittymiskyvyllä tarkoitetaan kuinka paljon kehitystoimenpiteillä nähdään saatavan taloudellista hyötyä. Edelle mainittujen kriteereiden attribuuteiksi ehdotettiin makrosijainnille alueellisen BKT:n suhdetta uusiin rakennushankkeisiin, mikrosijainnille keskimääräistä matka-aikaa ja kulkuvälinevaihtoehtoja aluekeskukseen, sopimushinnalle kohteen sopimushintojen neliöillä painotettua keskiarvoa, korjaustarpeille pitkän tähtäimen suunnitelmasta saatavaa korjaustarvearviota ja kiinteistön kehittymiskyvylle asiantuntijan toteuttamaa arviota kiinteistön kehityskelpoisuudesta. Tutkimus ei ottanut kantaa kriteereiden painotukseen tai attribuuttien mittaustulosten pisteyttämiseen, koska työ haluttiin pitää yleisellä tasolla ja edellä mainitut toimenpiteet olisivat vaatineet työn rajaamista koskemaan vain yhtä kiinteistösijoittajaa. Kokonaisuudessaan nähtiin, että yleisen mallin kehittäminen kiinteistöportfoliohallintaan on mahdotonta, johtuen mallissa käytettävien painotusten ja arvofunktioiden yksilöllisestä luonteesta. Tästä johtuen preferenssimallin laadinta olisikin parempi toteuttaa käyttäen vain yhtä kiinteistönomistajaa. Tässä työssä kuvattu prosessi antaa kuitenkin työn kohteena olleille kiinteistönomistajille valmiudet luoda kvantitatiivinen malli oman päätöksenteon tueksi. Prosessin tuloksena saatava malli ehdottaa perustuen kiinteistön sisäsyntyisiin tekijöihin, miten kiinteistöt tulisi lajitella eri salkkuihin. Malli on kuitenkin tarkoitettu vain päätöksentekijän avuksi, ei päätöksentekijäksi

When facilitating decisions in which some performance evaluations are uncertain, a decision must be taken about how this uncertainty is to be modelled. This involves, in part, choosing an uncertainty format {a way of representing the possible outcomes that may occur. It seems reasonable to suggest {and is an aim of the thesis to show {that the choice of how uncertain quantities are represented will exert some influence over the decision-making process and the final decision taken. Many models exist for multi-criteria decision analysis (MCDA) under conditions of uncertainty; perhaps the most well-known are those based on multi-attribute utility theory [MAUT, e.g. 147], which uses probability distributions to represent uncertainty. The great strength of MAUT is its axiomatic foundation, but even in its simplest form its practical implementation is formidable, and although there are several practical applications of MAUT reported in the literature [e.g. 39, 270] the number is small relative to its theoretical standing. Practical applications often use simpler decision models to aid decision making under uncertainty, based on uncertainty formats that `simplify' the full probability distributions (e.g. using expected values, variances, quantiles, etc). The aim of this thesis is to identify decision models associated with these `simplified' uncertainty formats and to evaluate the potential usefulness of these models as decision aids for problems involving uncertainty. It is hoped that doing so provides some guidance to practitioners about the types of models that may be used for uncertain decision making. The performance of simplified models is evaluated using three distinct methodological approaches {computer simulation, `laboratory' choice experiments, and real-world applications of decision analysis {in the hope of providing an integrated assessment. Chapter 3 generates a number of hypothetical decision problems by simulation, and within each problem simulates the hypothetical application of MAUT and various simplified decision models. The findings allow one to assess how the simplification of MAUT models might impact results, but do not provide any general conclusions because they are based on hypothetical decision problems and cannot evaluate practical issues like ease-of-use or the ability to generate insight that are critical to good decision aid. Chapter 4 addresses some of these limitations by reporting an experimental study consisting of choice tasks presented to numerate but unfacilitated participants. Tasks involved subjects selecting one from a set of five alternatives with uncertain attribute evaluations, with the format used to represent uncertainty and the number of objectives for the choice varied as part of the experimental design. The study is limited by the focus on descriptive rather than real prescriptive decision making, but has implications for prescriptive decision making practice in that natural tendencies are identified which may need to be overcome in the course of a prescriptive analysis.

Texto completoMultiple-criteria decision analysis (MCDA) aims at providing support in order to make a decision. MCDA methods allow to handle choice, ranking and sorting problems. These methods usually involve the elicitation of models. Eliciting the parameters of these models is not trivial. Indirect elicitation methods simplify this task by learning the parameters of the decision model from preference statements issued by the decision maker (DM) such as “alternative a is preferred to alternative b” or “alternative a should be classified in the best category”. The information provided by the decision maker are usually parsimonious. The MCDA model is learned through an interactive process between the DM and the decision analyst. The analyst helps the DM to modify and revise his/her statements if needed. The process ends once a model satisfying the preferences of the DM is found. Preference learning (PL) is a subfield of machine learning which focuses on the elicitation of preferences. Algorithms in this subfield are able to deal with large data sets and are validated withartificial and real data sets. Data sets used in PL are usually collected from different sources and aresubject to noise. Unlike in MCDA, there is little or no interaction with the user in PL. The input data set is considered as a noisy sample of a “ground truth”. Algorithms used in this field have strong statistical properties that allow them to filter noise in the data sets.In this thesis, we develop learning algorithms to infer the parameters of MCDA models. Precisely, we develop a metaheuristic designed for learning the parameters of a MCDA sorting model called majority rule sorting (MR-Sort) model. This metaheuristic is assessed with artificial and real data sets issued from the PL field. We use the algorithm to deal with a real application in the medical domain. Then we modify the metaheuristic to learn the parameters of a more expressive model called the non-compensatory sorting (NCS) model. After that, we develop a new type of veto rule for MR-Sort and NCS models which allows to take criteria coalitions into account. The last part of the thesis introduces semidefinite programming (SDP) in the context of multiple-criteria decision analysis. We use SDP to learn the parameters of an additive value function model

Texto completoTubos de aço de grande diâmetro, baixa espessura e alta resistência mecânica, possuem tendência à formação de rugas no lado compressivo do curvamento (intrados) ao serem curvados a frio. A presente dissertação descreve os principais códigos de projeto nacionais e internacionais, quanto à presença de rugas provenientes desse tipo de curvamento em dutos, e propõe um ângulo para o qual há a formação do enrugamento. Os códigos internacionais mostram-se conservadores quanto à presença de rugas nos tubos curvados, uma vez que o enrugamento é uma mudança geométrica que, a princípio, gera concentração de tensões e susceptibilidade à ocorrência de falhas por fadiga. Esta dissertação faz uso do método de elementos finitos para modelar a formação do enrugamento e determinar fatores de concentração de tensões, nestas regiões, para carregamentos de pressão interna. Os fatores encontrados são comparados com resultados encontrados na literatura e utilizados no cálculo contra a fadiga por meio de diferentes métodos: Markl, inclinações universais de Manson e ASME seção VIII divisão 2. Neste estudo foram utilizados tubos de aço estrutural API X70 com razão diâmetro espessura (D/t) variando de 20 a 100, modelados por meio do software Abaqus(r). Foram obtidas curvas com ângulo de 4°/diâmetro e enrugamentos severos, com razão entre a altura da ruga e o diâmetro do tubo (d/D) da ordem de 6,5% e fator de concentração de tensão chegando a 1,89. Os modelos de tubo enrugado não apresentaram falha na resistência mecânica à pressão interna aplicada, quando esta é suficiente para obtenção de tensão circunferencial nominal equivalente a 100% do limite de escoamento do material. Os resultados de vida em fadiga para os diferentes métodos aplicados variam de acordo com o método utilizado, mas todos apresentam redução na vida do tubo com presença de enrugamento severo. O estudo propõe que se utilize para o cálculo da vida em fadiga um procedimento conservador que associa o fator de concentração de tensão determinado por Rosenfeld com o método de cálculo contra a fadiga recomendado pelo código ASME VIII. O estudo sugere ainda, que sejam realizadas novas análises de forma a considerar o efeito Bauschinger e a instabilidade à flexão do modelo não avaliados no presente trabalho.
Large diameter, thin walled, high mechanical resistance steel pipe has a tendency to wrinkle on the compressive side (the intrados) of the bend when it is cold bent. This dissertation describes the principal national and international design codes that apply to wrinkling resulting from pipe cold bending, and it proposes an angle at which such wrinkling occurs. The international codes prove to be conservative regarding wrinkling in bent pipe, since a wrinkle is a geometric change, which at first causes a stress concentration and susceptibility to fatigue failure. The dissertation uses the finite element method to model the formation of wrinkling and to determine stress concentration factors in these areas for internal pressure loading. The resulting factors are compared with the results found in the literature and are utilized in calculating fatigue life by means of the following methods: Mark1, Mansons universal inclinations and ASME Section VIII Division 2. In this study API X70 structural pipe with a diameter thickness (D/t) ratio varying from 20 to 100 was utilized, and modeled using Abaqus(r) software. Bends with an angle of 4°/diameter and severe wrinkling resulted, with a ratio between the peak of the wrinkle and the diameter of the pipe (d/D) of about 6.5% and a stress concentration factor nearing 1.89. The wrinkled pipe models did not reveal any lack of mechanical resistance to the applied internal pressure when it is sufficient for obtaining a nominal circumferential stress equivalent to 100% of the yielding limit of the material. The fatigue life results for the different methods varied according to the method that was utilized, but all displayed a reduction in pipe life if there was severe wrinkling. The study proposes a conservative procedure to be utilized for calculating fatigue life. This procedure associates the stress concentration factor determined by Rosenfeld with the method for calculating fatigue recommended by the ASME VIII code. Furthermore, the study suggests that new analyses may be performed in order to consider the Bauschinger effect and the model bend instability, which the study did not evaluated.

Texto completoThis thesis provides data analysis on the selection process of the FY 2009–2011 Army Active Guard/Reserve (AGR) colonel selection boards. In this analytic study, logistic regression is used to study what variables influence colonel selection. The focus of this study is to aid Army senior leaders in the mentoring and development of future senior leaders by identifying criteria key to the selection of Army AGR colonels. A data set is compiled from 1144 individual promotion packets submitted across three selection boards. The 1144 packets correspond to 684 individuals. The findings suggest one’s zone of consideration, age, longest deployment, senior service college completion, possession of a master’s degree, battalion command, number of ratings as a lieutenant colonel, and the total percentage above center of mass ratings have a significant influence on selection.

Nesta tese, reconsideramos os critÃrios que caracterizam as funÃÃes discursivas dos processos anafÃricos a partir da anÃlise de anÃncios publicitÃrios. Tivemos como objetivo identificar as funÃÃes discursivas presentes nos gÃneros notÃcia, anÃncio, artigo de opiniÃo e piada, tendo como ponto de partida o quadro de funÃÃes sugerido por Ciulla (2008). Tomamos como pressuposta uma perspectiva cognitivo-discursiva da referenciaÃÃo, pela qual tem sido ampliada a concepÃÃo de anÃforas. Uma abordagem discursiva para a anÃlise de processos referenciais deve considerar nÃo apenas a expressÃo referencial em si, mas o conjunto de elementos contextuais convocados para a negociaÃÃo sociocognitivo-discursiva dos referentes. Partindo desse pressuposto, julgamos necessÃrio realizar uma rediscussÃo dos critÃrios utilizados para a anÃlise das funÃÃes discursivas desempenhadas pelos processos anafÃricos. Tomamos como fonte teÃrica para o estudo das funÃÃes discursivas o trabalho de Ciulla (2008), que objetivou estabelecer critÃrios que permitissem uma visÃo ampliada dos processos referenciais que nÃo apenas revelasse funÃÃes, mas tambÃm levasse em conta a mutabilidade caracterÃstica do processo de construÃÃo referencial e, portanto, suportasse constantes acrÃscimos e ajustes, conforme a observaÃÃo das diversas situaÃÃes de uso. Especificamente, extraÃmos do trabalho de Ciulla (2008) o quadro de funÃÃes discursivas sugeridas pela autora, a fim de as testarmos em outros gÃneros, neste caso, a notÃcia, o anÃncio, o artigo de opiniÃo e a piada. Tal aplicaÃÃo exige uma reorganizaÃÃo do quadro de funÃÃes, levando em consideraÃÃo as caracterÃsticas contextuais em que esses gÃneros sÃo praticados.
In this thesis, we reconsider the criteria that characterize the discursive functions of anaphoric processes from the analysis of advertisements. The goal was to identify the discursive functions present in the genres news, add, opinion article and joke, taking as its starting point the framework of functions suggested by Ciulla (2008). We assumed a cognitive-discursive perspective of referral, through which has been expanded the conception of anaphoras. A discursive approach for the analysis of referential processes must consider not only the referred expression itself, but also the set of contextual elements arranged to the sociocognitive-discursive negotiation of the referents. Based on this assumption, we believe it is necessary to conduct a rediscussion of the criteria used for the analysis of the discursive functions performed by the anaphoric processes. The main framework for the study of the discursive function is the work of Ciulla (2008), which aims at establishing criteria that allow a boader view of referential processes that could not only reveal functions, but could also take into account the characteristic mutability of the process of referential construction and that could, therefore, stand constant additions and adjustments, according to the observation of the diverse situations of use. Specifically, we extracted from Ciulla's work (2008) the framework of discursive functions suggested by the author in order to test it in other genres: news, add, opinion article and joke. This application demands a reorganization of the mentioned framework, considering the contextual characteristics in which these genres are practiced.

Ambientes dinâmicos e distribuídos são sistemas descentralizados que fornecem aos usuários recursos de consultas sobre um conjunto de fontes de dados heterogêneas, distribuídas e autônomas (peers). Sistemas de Integração de Dados, Peer Data Management System (PDMS) e Dataspaces são exemplos de tais sistemas. Eles são constituídos por peers que pertencem a um domínio específico e estão ligados entre si por meio de correspondências semânticas. No entanto, um desafio inerente em ambientes dinâmicos e distribuídos é o processo de reformulação de consulta entre um par de peers. Quando um usuário coloca uma consulta em um peer, a fim de adquirir mais informações, a consulta deve ser reformulada de acordo com o esquema dos peers vizinhos. Neste processo podem surgir alguns problemas como a perda semântica e a degradação da consulta. A perda semântica e degradação da consulta são problemas relacionados à perda de conceitos semânticos durante a reformulação. Por outro lado, em um ambiente semanticamente rico, ao invés de uma perda semântica, a consulta pode ter um enriquecimento semântico por meio da agregação de conceitos semanticamente relacionados durante a reformulação. Neste sentido, a consulta do usuário pode ser enriquecida e resultados semânticos mais ricos podem ser recuperados. Critérios de qualidade da informação têm sido usados em alguns trabalhos para avaliar o nível de qualidade dos elementos de um ambiente dinâmico e distribuído como, por exemplo, peers, dados e a resposta da consulta. Estes critérios são medidas dinâmicas proporcionadas pelo sistema e servem como uma pontuação que pode ser constantemente avaliada para obter o nível real de qualidade. Neste trabalho, apresentamos quatro critérios de qualidade da informação que medem a perda e o ganho de conceitos semânticos durante a reformulação da consulta entre os pares de peers. Nós apresentamos um exemplo da nossa abordagem e os algoritmos de avaliação de critérios. Também damos as nossas definições para os problemas de perda semântica e degradação da consulta. Por fim, apresentamos a experimentação que fizemos com o PDMS SPEED e os resultados obtidos.
Dynamic distributed environments are decentralized systems that provide users with querying capabilities over a set of heterogeneous, distributed and autonomous data sources (peers). Data Integration Systems, Peer Data Management Systems (PDMS) and Dataspaces are examples of such systems. They are composed by peers that belong to a specific domain and are linked to each other by correspondences (semantic connections). Nonetheless, a challenge inherent to dynamic distributed environments is the query reformulation process between a pair of peers. When a user poses a query at a peer, in order to acquire more information, the query should be reformulated in accordance with the neighbor peers schema. In this process some problems as semantic loss and query degradation can arise. The semantic loss and query degradation are problems related to the loss of semantic concepts during query reformulation. In the other hand, in such a semantic environment instead of a semantic loss the query can have a semantic enrichment by aggregating semantic related concepts during reformulation. In this sense, the user’s query can be enriched and semantically richer results can be delivered. Information Quality criteria has been used in some works to evaluate the level of quality of the distributed dynamic environment’s elements such as, peers, data and query answer. These criteria are dynamic measures provided by the system and serve as scores that can be constantly evaluated to get the actual level of quality. In this work we present four Information Quality criteria that measure the loss and enrichment of semantic concepts during query reformulation among peers. We present an example of our analysis and the algorithms that implement the evaluation of the presented criteria. We also give our definitions to the semantic loss and query degradation problems. Finally, we present the experimentation we have done with the SPEED PDMS and the obtained results.
