Masat, Mehmet. "Design And Implementation Of Hot Precision Forging Die For A Spur Gear." Master's thesis, METU, 2007. http://etd.lib.metu.edu.tr/upload/12608550/index.pdf.

Full text

Abstract:

There is a strong need in forging industry to reduce waste of material, improve quality, and reduce cost of forgings. About 30% of the material is wasted during conventional closed-die forging. Therefore, in order to reduce the cost of forged products and to obtain near-net or net shape parts, new forging methods should be applied. Precision forging concept is a cost-effective way to produce net-shape or near-net shape components. In recent years, there has been an increased interest in the production of gears by the net-shape forging technique. This has specific advantages over the traditional manufacturing processes of cutting gears such as hobbing, turning, and grinding including savings on cost and raw material, increased productivity, and gears with higher dynamic properties than conventionally cut ones. In this study, precision forging of a particular spur gear has been investigated. The precision forging die set has been conceptually designed and modeled in a computer aided design environment. The forging process of particular spur gear has been simulated by using a commercially available finite volume program. After the successful simulation results, the prototype die set and the tube-shaped billets were manufactured. The real-life experiments have been realized by using 1000 tons mechanical forging press available in METUBILTIR Research and Application Center Forging Laboratory. The results have been compared with the computer simulations. After the real-life experiments, it has been observed that the conceptual die design is appropriate and near-net shape spur gears are successfully obtained by the proposed precision forging die set.

Abstract:

With the aim for higher economical efficiency, considerable and radical changes have occurred in the worldwide electricity sector since the beginning of 1980s. By that time, the electricity sector has been controlled by the state-owned vertically integrated monopolies which manage and control all generation, transmission, distribution and retail activities and the consumers buy electricity with a price set by these monopolies in that system. After the liberalization and restructuring of the electricity power sector, separation and privatization of these activities have been widely seen. The main purpose is to ensure competition in the market where suppliers and consumers compete with each other to sell or buy electricity from the market and the consumers buy the electricity with a price which is based on competition and determined according to sell and purchase bids given by producers and customers rather than a price set by the government. Due to increasing competition in the electricity market, accurate electricity price forecasts have become a very vital need for all market participants. Accurate forecast of electricity price can help suppliers to derive their bidding strategy and optimally design their bilateral agreements in order to maximize their profits and hedge against risks. Consumers need accurate price forecasts for deriving their electricity usage and bidding strategy for minimizing their utilization costs. This thesis presents the determination of system day ahead price (SGOF) at the day ahead market and system marginal price (SMF) at the balancing power market in detail and develops artificial neural network models together with multiple linear regression models to forecast these electricity prices in Turkish electricity market. Also the methods used for price forecasting in the literature are discussed and the comparisons between these methods are presented. A series of historical data from Turkish electricity market is used to understand the characteristics of the market and the necessary input factors which influence the electricity price is determined for creating ANN models for price forecasting in this market. Since the factors influencing SGOF and SMF are different, different ANN models are developed for forecasting these prices. For SGOF forecasting, historical price and load values are enough for accurate forecasting, however, for SMF forecasting the net instruction volume occurred due to real time system imbalances is needed in order to increase the forecasting accuracy.

Abstract:

This diploma thesis deals with the experimental and numerical analysis of volume changes of fine-grained concrete. Experiments were carried out, measuring both the length changes as well as the mass losses and the internal temperature of the test specimens made from fine-grained concrete. The measurements were divided into two parts (phases). The first phase took approx. 72 hours. The second phase was focused on the long-term measurements and will be completed after stabilization of the mass losses and length changes. In the diploma thesis, the first phase of measurement was elaborated in detail, both in terms of experimental and numerical analysis. In addition, a C # .NET program was created to facilitate the processing of raw measurement data from the data logger. Finally, a comparative calculation was performed according to the model B4, where the result of the calculation was compared with the results of the experiment.

Abstract:

A growing recognition of the need for effective marine environmental management as a result of the increasing exploitation of marine biological resources has highlighted the need for high speed ecological seabed mapping. The practice of mapping making extensive use of satellite remote sensing and airborne platforms is well established for terrestrial management. Marine biological resource mapping however is not readily available except in part from that derived for surface waters from satellite based ocean colour mapping. Perhaps the most fundamental reason is that of sampling difficulty, which involves broad areas of seabed coverage, irregularities of seabed surface and depth. Conventional grab sample techniques are widely accepted as a standard seabed mapping methodology that has been in use long before the advent of acoustic techniques and continue to be employed. However. they are both slow and labour intensive, factors which severely limit the spatial coverage available from practical grab sampling programs. While acoustic techniques have been used for some time in pelagic biomass assessment, only recently have acoustic techniques been applied to marine biological resource mapping of benthic communities. Two commercial bottom classifiers available in the market that use normal incidence echosounders are the RoxAnn and QTC View systems. Users and practitioners should be cautious however when using black box implementations of the two commercial systems without a proper quality control over raw acoustic data since some researchers in their studies have indicated problems with these two bottom classifiers such as, among others, a depth dependence. In this thesis, an alternative approach was adopted to the use of echosounder returns for bottom classification.The approach used in this study is similar to,~ used in the commercial RoxAnn system. In grouping bottom types however, Multivariate analysis (Principal Component Analysis and Cluster Analysis) was adopted instead of the allocation system normally used in the RoxAnn system, called RoxAnn squares. In addition, the adopted approach allowed for quality control over acoustic data before further analysis was undertaken. As a working hypothesis, it was assumed that on average 0 and aE2 = 0 where E1 and E2 are the roughness and hardness indices, respectively, and RO is the depth. For roughness index (E1), this was achieved by introducing a constant angular integration interval to the tail of the first OM returns whereas for hardness index (E2), this was achieved by introducing a constant depth integration interval. Since three different frequencies, i.e. 12, 38 and kHz, were operated, Principal Component Analysis was used here to reduce the dimensionality of roughness and hardness indices, formed from the three operated qu frequencies separately. The k-means technique was applied to the first principal component of roughness index and the first principal comp component of hardness index to produce separable seabed types. This produced four separable seabed types, namely soft-smooth, soft-rough, hard-smooth and hard-rough seabeds.Principal Component Analysis was also used to reduce the dimensionality of the area backscattering coefficient sA, a relative measure of biomass of benthic mobile biota. The bottom classification results reported here appear to be robust in that, where independent ground truthing was available, acoustic classification was generally congruent with ground truth results. When investigating the relationship between derived bottom type and acoustically assessed total biomass of benthic mobile biota, no trend linking the two parameters, however, appears. Nevertheless, using the hierarchical agglomerative technique applied to a set of variables containing average first principal component of the area backscattering coefficient sA, the average first principal component of roughness and hardness indices, the centroids of first principal component of roughness and hardness indices associated with the four seabed types and species composition of fish group of the common species in trawl stations available, two main groups of quasi acoustic population are observed in the North West Shelf (NWS) study area and three groups are observed in the South East Fisheries (SEF) study area. The two main groups of quasi acoustic population in the NWS study area and the three main groups of quasi acoustic population in the study area are associated with the derived seabed types and fish groups of the common species.

Abstract:

Dans la simulation des arcs électriques, une estimation de la contribution radiative est indispensable pour fournir une description satisfaisante du comportement thermique du plasma. La prédiction précise de la divergence du flux radiatif (DFR) est essentielle pour déterminer l'évolution de la température de l'arc. Afin de décrire avec précision les effets radiatifs, la résolution de l'équation de transfert radiatif (ETR) est nécessaire moyennant la connaissance du coefficient d'absorption du milieu. Malheureusement, ce coefficient étant dépendant de la température et de la longueur d'onde, cette équation s'avère complexe à résoudre et coûteuse en temps de calcul. De nombreuses méthodes approximatives sont ainsi développées pour simplifier le calcul des propriétés radiatives. Dans ce travail, nous décrivons finement le spectre d'un plasma d'air avec près de 7.106 points en fréquence (ou longueur d'onde). A partir de ce découpage, nous calculons la DFR, soit à partir de la méthode approchée du coefficient d'émission nette (CEN) basée sur une simplification géométrique du plasma, soit à partir de coefficients moyens d'absorption (CMA) obtenus après découpage du spectre en 6 intervalles spectraux utilisant différentes moyennes (Classique, Planck, Planck modifiée et Rosseland), soit à partir d'un calcul " exact " correspondant à la résolution directe de l'ETR. Les calculs sont réalisés pour 9 configurations simples en 1D simulant un plasma cylindrique dont la température ne varie qu'en fonction du rayon. Les différentes étapes de calcul y sont présentées mettant en évidence l'influence de certains paramètres comme la largeur et la température maximale du profil de température, la pression, les vapeurs de cuivre .... Une grande partie de ce travail porte sur la comparaison des résultats obtenus par le calcul " exact " avec ceux déduits des différentes méthodes approchées dans le but de valider leur utilisation ainsi que leur précision. Cette comparaison nous a permis de développer une méthodologie d'optimisation apportant des améliorations au calcul des méthodes approchées (CEN et CMA) permettant ainsi une meilleure description du rayonnement. Enfin, ce travail présente le développement d'un modèle d'arc libre 2D axisymétrique résolvant les équations de Navier-Stockes et de Maxwell par la méthode des volumes finis. Celui-ci permet une comparaison entre la méthode du CEN et la méthode P1 qui tient compte de l'absorption du rayonnement des zones froides In the simulation of electrical arc, the representation of radiative contribution is essential to provide a satisfactory description of the thermal behavior of the plasma. The accurate prediction of the radiative emission is essential to determine the evolution of the arc temperature. For a precise description of radiative effect, a resolution of the Radiative Transfer Equation (RTE) , is necessary necessary with knowledge of the absorption coefficient. Unfortunatly, the complexity of this coefficient - dependent on temperature and wavelenghth- makes this equation impossible to solve in term of computational cost. This is why many approximative methods are developed to simplify the calculation of the radiative properties. In this work, we have carried out a detailed description of the spectrum of an air plasma with about 7.106 points on frequency. From this description, we have calculated the divergence of the radiative flux either from the net emission coefficient (NEC) based on a geometric simplification of the plasma, or from the mean absorption coefficients (MAC) calculated after a division of the spectrum into 6 intervals in which we have used different mean functions (Classic, Planck, Planck Modified and Rosseland), or from an exact calculation corresponding to a direct solution of the RTE. This is why many approximative methods were developed to reduce numerical demands . The calculations have been done for 9 simplified configurations in 1D assuming a cylindrical plasma for which the temperature profile varies only with the radius. The different steps of the work are presented and highlight the influence of several parameters such as the temperature profile, the pressure, the copper vapors.... A great part of this work deals with the comparison between the results obtained from the exact resolution with the results deduced from the other approaches in order to validate the use and the accuracy of the different methods. This comparison allowed us to develop an optimization methodology providing improvements to the calculation of the approximate methods (NEC and MAC) allowing a better description of the radiative properties. Finally, this work presents the development of an axisymmetric 2D free-burning arc model solving the Navier-Stockes and Maxwell equations by the finite volume method. This model allows a comparison between the NEC method and the P1 method which takes into account the absorption of radiation in the cold areas

Thesis: M. Eng. in Logistics, Massachusetts Institute of Technology, Engineering Systems Division, 2015. "June 2015." Cataloged from PDF version of thesis. Includes bibliographical references (pages 93-94). Airfreight forwarding companies must develop accurate forecasting tools to analyze the suitability and attractiveness of each incoming bidding process, to decide whether to participate in a tender and how to define the optimal commercial strategy. The "1:6" weight/volume ratio establishes that whenever the cargo ratio is different from 1:6 (1m3:167 kg) forwarders must pay the higher rate: either volume or weight. Given the main constraints in terms of volumetric capacity and maximum weight per volumetric unit, the most profitable business opportunities consist of combining in the same load compatible products with different densities. The main target is to come close as possible to the desired 1:6 ratio, to minimize the average price per load. To remain competitive, airfreight forwarding firms must improve their consolidation techniques, to combine in the same load cargo with compatible densities. The availability of robust analytical resources will allow airfreight industry companies to improve their rate of success, in terms of enhancing both efficiency (by increasing air volumes and densities) and profitability (by minimizing the Net Achieved Rate). This thesis develops an analytical model based on meaningful metrics to provide airfreight forwarders with an accurate and solid forecasting tool to select the bids under consideration that best match with their current portfolio in terms of air volume usage for a given origin-destination lane. It also predicts breakeven rates to increase profitability by minimizing the Net Achieved Rate. Furthermore, the model provides a series of metrics and visualization tools to help air freight forwarding companies to improve their understanding of their current portfolio for a given origin-destination lane and define their commercial strategy with respect to air freight cargo tenders. by Per Niklas Blomberg and Ramon Gras Alomá.

Full text

Abstract:

La malattia policistica renale autosomica dominante (Autosomal Dominant Polycystic Kidney Disease - ADPKD) rappresenta la più comune malattia renale ereditaria ed è causa dell’ultimo stadio della malattia renale (End Stage Renal Desease - ESRD) circa nel 10% dei pazienti. Negli ultimi dieci anni, la velocità di filtrazione glomerulare (Glomerular Filtration Rate - GFR) e la misura della creatinina serica sono stati gli unici biomarker disponibili per monitorare la progressione della malattia nei pazienti con ADPKD. Purtroppo diversi studi hanno evidenziato che i valori di GFR rimangono per anni entro i limiti di normalità, e diventano anomali solo verso gli ultimi stadi della malattia, e la concentrazione di creatinina serica è ottima per valutare la funzionalità, ma non dà alcun tipo di informazione sulle anomalie strutturali del rene. Rimane quindi un’indiscussa necessità di marcatori in grado di monitorare l’effettiva progressione della malattia, la crescita delle cisti e la risposta ai trattamenti farmacologici, disponibili da poco in Italia, fin dai primi stadi del disturbo. Il volume totale renale (Total Kidney Volume - TKV) è un parametro riconosciuto dal Consortium of Renal Imaging Studies in Polycystic Kidney Disease (CRISP) come valido marker per la diagnosi e la prognosi dell’ADPKD. Tuttavia la relazione che intercorre tra il TKV e la funzionalità renale nei pazienti con ADPKD rimane di difficile comprensione, a causa dei numerosi e contraddittori fattori che caratterizzano la patologia. Inoltre, l’utilizzo del TKV come marker per monitorare la progressione di ADPKD ha sollevato il dubbio su quale sia il modo migliore di misurare il TKV e i cambiamenti al suo interno. Pertanto, questa tesi si propone di formulare una rassegna aggiornata delle tecniche di imaging che possono essere utilizzate per misurare il TKV nei pazienti con malattia renale policistica, sottolineando le ricadute positive e quelle negative di ogni approccio.

Abstract:

Partendo da alcune proprietà delle serie finanziarie ben note in letteratura come distribuzione empirica non Normale (leptocurtosi e asimmetria), eteroschedasticità e volatility clustering (persistenza), si analizzano alcuni modelli che riescano a catturare alcune di queste caratteristiche, facendo riferimento in particolare ai modelli ARCH e GARCH (con le loro varianti e evoluzioni). Una volta specificata un’equazione per la media e testata la presenza di effetti ARCH, questi modelli prevedono la specificazione di un’equazione della varianza condizionatamente autoregressiva. In questo elaborato si cercherà di capire, con riferimento ai rendimenti giornalieri dell’indice FTSE Mib, se l’inserimento nell’equazione della varianza condizionata di alcune variabili esplicative, come l’indice di volatilità implicita dell’indice (l’IVI) e il volume delle contrattazioni, possano aggiungere informazione e migliorare il potere previsionale del modello (come suggerito ad esempio da Blair, Poon e Taylor e da Lamoureux e Lastrapes).

Trinità of Cava de’ Tirreni and Montecassino, from thè archive of thè Società Napoletana di Storia Patria, from thè diocesan historical archives of Salerno and Potenza, from thè Archivi di Stato of Naples, of Rome and of Potenza, from thè Archivio Storico Capitolino, thè Secret Archive and thè Vatican Library and thè National Library of Naples. The work is structured in two interrelated parts, both composed of five chapters. In thè first part, anticipated by a premise dedicated to thè sources and studies on thè subject, are highlighted origins, developments, relationships and activities that have characterized thè Cistercian abbeys of thè whole Continental Mezzogiorno, with some reference also to thè Sicilian monasteries where thè treatment require. In thè second section thè events related to some, specific, monasteries are illustrated in detail, i.e. S. Maria della Ferraria near Vairano Patenora (dioceses of Teano), S. Pietro della Canonica, at thè gates of Amalfi, S. Maria di Realvalle near Scafati e S. Maria del Sagittario near Chiaromonte (dioceses of Anglona). In a further chapter, I examine a series of small monasteries that thè sources or thè tradition lead back to those inhabited by white monks but whose testimonies are very dubious. In particular, we deal with thè peculiar case of thè monastery of S. Leonardo de Strato in thè archdiocese of Salerno which, although in one of thè first documents relating to it was inhabited by Cistercian monks, was subjected to episcopal jurisdiction in such a way as to prevent fact, an effective affiliation to thè Order. In both sections there are numerous and essential references to thè Roman abbeys of Casamari and Fossanova, whose events are intimately linked to thè diffusion and organization of thè Cistercians in Mezzogiorno. The study reveals thè deep relationship between thè abbeys and thè locai context that, in some cases, allows comparisons with what is attested in other areas of thè Peninsula and induces to re-evaluate thè ability of thè South-Italy Cistercians to attract thè devotion from thè laity. In thè same way, thè interest for thè insertion in urban circuits that characterizes different abbeys shows a modus operandi quite unlike that found among thè counterparts of north-western Italy. A fundamental question must also be remembered: thè objective distortion caused by thè documentary loss that has struck both thè monastic archives and thè regnum Chancelleries. This has certainly contributed to creating an image of thè Cistercians as a completely minority reality within thè southern monastic panorama, whereas, on thè contrary, to a more in-depth research, several communities show they have exercised a sure influence on their territories.

Abstract:

Nel presente lavoro viene descritto come è stata ottimizzata, a livello software e hardware, la procedura di controllo della pressione in uno strumento manometrico utilizzato per la misura della quantità di idrogeno assorbita e desorbita da parte di metalli. Dopo una breve introduzione sulle caratteristiche dell'idrogeno che lo rendono così appetibile dal punto di vista energetico, viene esposta la teoria alla base del processo di formazione di idruri metallici. Vengono dunque descritte le due principali tecniche di caratterizzazione di questi sistemi, ovvero le cinetiche e le isoterme pressione-composizione (PCI), e il metodo di misura adottato, ovvero quello volumetrico. Successivamente si passa alla descrizione delle componenti hardware del sistema, per poi soffermarsi sull'analisi dettagliata dell'algoritmo del software implementato, spiegando i problemi affrontati e le soluzioni adottate, riportando anche alcune formule utili ricorrenti. Infine, vengono esposti i risultati ottenuti da misure di cinetiche e PCI per il sistema MgH2 (idruro di magnesio).

Abstract:

The ongoing globalization of companies has resulted in a highly competitive business climate where companies have to be cost-effective but still flexible with fast response to customer feedback and present in the international scene. In order to meet the fast paced technological development from the competition and changing demand of the customers, companies focus on creating new products and reducing their time-to-market with an early product launch to gain profits from increased market shares. However, in order to maintain profitability of the new product, it becomes even more important for the company to quickly deploy a full-scale production of the product, also known as the production ramp-up phase. Despite being known as a major cost driver in new product development projects, production ramp-up is a research area which have yet received sparse attention compared to research on product launch and time-to-market in new product development projects. However, with shorter product life-cycles and higher market competition it has resulted in a need to shorten the length of a new product’s ramp-up time without making any trade-off to the cost-effectiveness of the ramp-up project and the end product’s final quality. The study identifies the common problems in volume production of a contract electronics manufacturer and their sources of disturbances from the new product introduction process. It also identifies the factors influencing the new product introduction process at the company and how these factors are connected different sources of disturbances. To identify these findings, a single case study was designed and performed at Orbit One AB, a contract electronics manufacturer with a low-volume production of products. The data collection course was executed in an iterative manner over a period of four months through interviews, observation and internal documentation and was backed up and analyzed with a literature study. The data collection through interviews was carried out in two separate rounds, where the first round of interviews was focused on identifying the common problems in volume production and the second round was focused on the factors influencing the output from the new product introduction process. The discoveries from the interviews were analyzed together with the other sources of collected data to reach a conclusive analysis. The results of the study showed that the most common problems in volume production of the company could be traced to six different sources of disturbances: Product, Production System, Design-Production Interface, Quality, Resource Management, and Personnel. The most common problems could also be summarized as: Problems with manufacturability of product; High variation of process performance, Poor correctness of information, Quality issues with products, and High workload on resources. The factors identified in the findings of the study shows that there are multiple and connected factors which affects the final output of the new product introduction process which corroborates with earlier studies and research in the area of production ramp-up. The study did identify two factors which has not been identified by other ramp-up studies, these were: Lack of organizational project culture and customer flexibility.

Abstract:

Valutazione funzionale delle capacità fisiche nel giocatore di basket in carrozzina d’alto livello vuole esser d’aiuto a tutti i preparatori che si interessano di questo sport, al fine di fornire delle linee guida utili ad una programmazione metodologica più rispondente alle esigenze biomeccaniche e neuromuscolari del basket in carrozzina. La valutazione, è avvenuta testando giocatori con punteggio di classificazione 1; 2; 3; 4; 4,5, maschi e femmine delle Nazionali italiane. Nel basket in carrozzina, il punteggio viene attribuito dalla commissione classificatrice (1 medico ed 1 tecnico), in relazione al grado di disabilità motoria ed alle capacità funzionali dell’atleta, dimostrate in campo durante il gioco. L’obiettivo della ricerca è stato raggiunto attraverso lo svolgimento dei seguenti test: test “20 m sprint” (che valuta la capacità di “accelerazione”); test “lancio della palla zavorrata dal capo/petto” (che valuta la capacità di “forza”); test “dell’8 con e senza palla” (che valuta la capacità tecnica di “conduzione del mezzo meccanico”); test del “tiro dalla zona della campana” (che valuta la capacità tecnica di “tiro a canestro”); test del “tiro di precisione al bersaglio” (che valuta la capacità tecnica di “passaggio”); match analysis delle fasi di “gioco effettivo” (che valuta tempo, posizione, velocità, distanza e direzione, di ogni giocatore durante la partita). I test sono stati svolti nel campo da basket regolamentare. Materiali utilizzati: cronometro; metro avvolgibile; nastro adesivo; palla zavorrata di 3Kg; coni in plastica; fischietto; software sistema SPI 10 (GPSport Systems, Pty. Ltd. 2003, Australia). Risultati: dai dati ottenuti si evince che il preparatore fisico, deve porre attenzione al raggiungimento dell’assetto ottimale tra giocatore e mezzo meccanico e mirare ad una preparazione fisica personalizzata, che in generale punti sullo sviluppo della forza degli arti superiori e della parte superiore del tronco, al fine di ottenere il massimo livello di prestazione. Esercitazioni personalizzate nell’ambito dello sport disabili permettono la miglior espressione motoria delle capacità residue e la possibilità di meglio tutelare il giocatore da naturali disequilibri biomeccanici relativi alla tecnica sportiva. Nel basket in carrozzina, la forza espressa dai giocatori rimane più elevata di quella espressa dalle giocatrici. Nel gioco, le velocità intermedie sono quelle più rappresentative e il play percorre le distanze maggiori, le accelerazioni più importanti in attacco e in difesa, ma subisce il maggior numero di forti impatti destabilizzanti. Thesis aims to help all those involved in thereparation of this sport by laying down useful guidelines for a methodical approch to ascertain the biomechanical and neuromuscolar requirements of wheelchair basket ball. An evaluation was made testing both male and female Italian national players with a points classification of 1; 2; 3; 4 and 4.5. In wheelchair basketball points are attributed by the classification commission (one medical and one technical), in relation to the degree of physical disability and the functional capabilities of the athlete, as demonstrated on court during play. Research evaluation used the following tests: (i) a 20 metre sprint (to asses the ability to accelerate), (ii) tossing a weighted ball from the head or chest (to asses strength), (iii)performing a figure of eight (with and without a ball) , ( to asses the players technical ability to drive the wheel chair) ; (iv)throwing within the bell zone (to asses technical ability to shoot for goal), (v)throwing at a target ( to asses technical ability to pass the ball ); (vi) a match analysis of “effective play” (evaluating the time, position, speed, distance and direction of each player during the match). All tests were carried out in a standard basketball court. Materials: stop watch, extendable tape measure, adhesive tape, 3kg medicine ball, plastic cones, whistle , SPI 10 soft ware system (GPSport Systems, Pty. Ltd. 2003 Australia). Results: from the data obtained it was clear that physical preparation must seek to find the optimum relationship between the player nd his mechanical means of propulsion and aim at personalized physical preparation, in general concentrating on developing strength in the arms and upper body, thereby achieving a maximum level of performance. Personalized training in the field of disabled sport allows the best physical expression of residual abilities and protects te player from naturally occurring biomechanical imbalances in technique. In wheelchair basketball, the force produced by a male player is still higher than that produced by a female player. During play an intermediate speed is most common and more distance is covered, acceleration is most important during attack and defence but the greatest number of hard destabilizing impacts

Orientador: Maria Inez Espagnoli Geraldo Martins Banca: João Donato Scorvo Filho Banca: Teresa Cristina Ribeiro Dias Koberstein Resumo: Nos últimos anos, a demanda pelo pescado tem aumentado significativamente. Atualmente, a pesca, que contribui com a maior parte deste produto, vem apresentando estagnação, ou ligeira queda na oferta em alguns anos como foi o caso de 2006. Em contrapartida, a aquicultura moderna, que passa por grandes avanços científicos e tecnológicos, vem suprindo esta deficiência no mercado. O Brasil, detentor de 12% de toda água doce mundial, deverá se tornar brevemente um grande produtor no cenário mundial. Um dos grandes diferenciais do país, além de possuir clima favorável, é a disponibilidade de grandes reservatórios, que tem sido aproveitado para o cultivo de peixes em tanques-rede. O presente estudo, desenvolvido em piscicultura comercial, no Reservatório de Furnas, curso médio do rio Grande, município de São José da Barra MG teve como objetivo comparar os principais indicadores zootécnicos e econômicos da tilapicultura em sistema super-intensivo (tanques-rede) em duas diferentes dimensões 6 e 18 m3. Foram utilizados 12.960 juvenis machos revertidos da tilápia-do-nilo (Oreochromis niloticus). Durante todo o período experimental, os peixes receberam ração extrusada especial para tilápias em cultivos super-intensivo e a oferta variou de acordo com a biomassa e temperatura da água, iniciando com 8% e decrescendo até 1%. Foram avaliados os seguintes índices zootécnicos: sobrevivência (%), peso médio (g), biomassa (kg), ganho de biomassa (kg), ganho em peso diário (g), conversão alimentar aparente e densidade (kg/m3). A análise econômica foi elaborada a partir da determinação do custo total de produção e do lucro de cada tratamento. Os dados deste estudo permitem concluir que, embora não diferindo nos principais indicadores zootécnicos, a produção de tilápias em tanques-rede de maior dimensão proporcionou menor custo total médio e maior rentabilidade Abstract: In the past few years, demand for fish has increased significantly. At present, fishing, which contributes with the largest part of this product, has shown stagnation or slight falling in the offer in some years, as in the case of 2006. On the other hand, modern aquiculture, with technological and scientific improvement, has been supplying this deficit on the market. Brazil, with 12% of the world's fresh water, will probably become one of the greatest consumers soon. Besides the favorable weather, there is also the availability of large reservoirs, which has been used for the growing of fish in net cage. The present study, developed at Furnas reservoir, medium course of Grande river, in São José da Barra/MG, had as its aim compare the economic and zootechnic indicators of tilapiculture in super intensive system net cages in two different dimensions 6 and 18 m3. 12,960 reversed male juvenils from Nile tilapia were used (Oreochromis niloticus). During the experiment the fish received (extrusada) special ration for tilapia in super intensive culture and the offer varied according to the biomass and water temperature, beginning with 8% and decreasing until 1%. The following zootechnic indexes were evaluated: survival (%), average weight (g), biomass (kg), gain of biomass (kg), gain of daily weight (g), apparent nutritional conversion and density (kg/m3). The economic analysis was made after the determination of the total cost of the production and the profit of each treatment. The data in this study allows the conclusion that the production of tilapia in (net cages) of bigger dimension offered bigger rentability Mestre

Abstract:

Negli ultimi anni si è registrato un crescente interesse verso lo studio dei flussi commerciali internazionali per effetto delL'instabile contesto economico odierno. In particolare una delle principali grandezzE economica osservate è la bilancia commerciale di uno stato, elemento rilevante della la bilancia dei pagamenti per conoscere la posizione di un'economia rispetto ai propri partner. Lo scopo dell'analisi proposta è quello di ottenere una stima dell'equazione delle esportazioni di un paese, analizzando le equazioni che descrivono i rapporti del paese rispetto ai suoi maggiori partner commerciali. L'analisi è stata svolta per gli Stati Uniti, considerando non solo la totalità delle esportazioni, ma anche le singole equazioni relative ai maggiori partner commerciali (Canada, Messico, Giappone, Germania e Gran Bretagna), considerando come variabili indipendenti la domanda estera dei beni del paese esportatore e la competitività di prezzo dello stesso. I dati utilizzati per l'analisi sono stati estratti da numerosi database, con copertura temporale dal 1986 ad oggi, e frequenza trimestrale. La metodologia statistica applicata tiene conto della non stazionarietà delle serie storiche economiche, caratteristica che invalida la tradizionale inferenza statistica.

Abstract:

L’aumento e la conservazione della cavità alveolare permettono di preservare l’altezza residua dell’osso alveolare.Gli effetti dell’exodonzia includono: il riassorbimento dell’osso alveolare, l’atrofia dell’osso basale e della cresta edentula. Il riassorbimento della cresta alveolare si manifesta rapidamente dopo l’avulsione dell’elemento dentario e influenza sia la possibilità, quando programmato, di posizionare impianti , sia il risultato estetico della riabilitazione protesica.Il mantenimento dei volumi consente di ottenere una dimensione dei tessuti molli adiacenti (papilla) sufficiente.Si sono selezionati siti in cui effettuare avulsioni con la tecnica di preservazione dell'alveolo e posizionare collagene bio-riassorbibile.E’ stato valutato con misurazioni l’aumento e/o il mantenimento del volume alveolare e della cresta ossea sia in casi di riabilitazione complesse implanto-protesica (full-arch) sia in riabilitazione di singoli denti.I casi trattati sono stati valutati con uno studio istologico per valutare gli effetti a distanza della rigenerazione con collagene nei siti post-estarattivi.I risultati si sono dimostrati incoraggianti dal punto di vista clinico e quindi si può mettere in evidenza la predicibilità di questa tecnica nel preservare i volumi dei tessuti molli nelle zone post-estrattive.

Abstract:

Lo scopo dello studio in questione è quello di fornire una panoramica sulla ricerca nel campo del neuroimaging strutturale avanzato incentrata sui disturbi dello spettro autistico. Viene trattato l’autismo partendo dal suo riconoscimento nel Manuale Diagnostico e Statistico dei Disturbi Mentali, catalogato tra i disturbi pervasivi dello sviluppo, fino ad arrivare alle più moderne tecniche di analisi strutturale con risonanza magnetica. Viene evidenziata l’altissima eterogeneità dello stesso che ha portato alla necessaria divisione in sottogruppi eziologicamente più omogenei. Vengono illustrate le fasi dello sviluppo cerebrale inerenti ai primi anni di vita, antecedenti al periodo tipico di diagnosi, che accomunano la maggioranza dei casi, grazie alle quali si spera di poter anticipare significativamente l’età media di una diagnosi attendibile. Negli ultimi anni si è cercato di sviluppare framework in grado di riconoscere i soggetti che ne sono colpiti solo sulla base di scansioni di risonanza magnetica mediante tecniche di machine learning. In particolar modo, sono di interesse le acquisizioni a 6, 12 e 24 mesi, illustrative di un periodo di elevata plasticità cerebrale. Oltre alle anomalie macroscopiche di volume e di estensione tipiche di questa fascia sensibile, vengono riportati anche alcuni cluster corticali distintivi dell’autismo. Questi si sono rivelati utili non tanto per la diagnosi, quanto per la classificazione dei sottogruppi, giustificando la relazione tra una malformazione corticale localizzata in un lobo ed una relativa funzionalità cognitiva o motoria inusuale. Viene fatta menzione di alcuni network internazionali e pubblici dediti alla raccolta di dataset di soggetti affetti dal disturbo in parallelo a soggetti sani, i quali hanno reso possibile una collaborazione tra la comunità scientifica permettendo ai ricercatori di condividere i dati da loro raccolti e le rispettive conclusioni che ne sono derivate.

Abstract:

This literary/historical novel details the life of African-American Deputy US Marshal Bass Reeves between the years 1838-1862 and 1883-1884. One plotline depicts Reeves’s youth as a slave, including his service as a body servant to a Confederate cavalry officer during the Civil War. Another plotline depicts him years later, after Emancipation, at the height of his deputy career, when he has become the most feared, most successful lawman in Indian Territory, the largest federal jurisdiction in American history and the most dangerous part of the Old West. A preface explores the uniqueness of this project’s historical relevance and literary positioning as a neo-slave narrative, and addresses a few liberties that I take with the historical record.

Abstract:

Lo studio affronta gli effetti e le potenzialità derivanti dall’aumento della capacità di invaso nel sistema di approvvigionamento idrico della Romagna a seguito dell’introduzione di un ulteriore serbatoio, collocato sul bacino del fiume Rabbi, ed allacciato alla rete attuale. La funzione principale del nuovo serbatoio è quella di invaso ausiliario, ovvero fornisce acqua all’invaso di Ridracoli nei momenti in cui questo viene a trovarsi in condizioni di scarsità idrica, smorzando, o, eventualmente, annullando i periodi di crisi. Lo studio è stato condotto ipotizzando due scenari di possibile allacciamento, e facendo variare la capacità di invaso sul Rabbi da 1 a 30 Mmc, al fine di ricercare le sue dimensioni ottimali. Il primo scenario ipotizza di inviare l’acqua dal Rabbi alla diga di Ridracoli per mezzo di un by-pass indipendente, mentre, il secondo, tramite un collegamento alla galleria di gronda; l’incremento di volume potabilizzato è stato confrontato sia con quello storico, sia con simulazioni che implementano regole di gestione ottimizzata del serbatoio di Ridracoli. L’analisi è stata condotta implementando un codice numerico in ambiente Matlab, in grado di restituire in output, per ciascuno scenario, l’aumento di volume potabilizzato a Ridracoli. Dai risultati si evince che una capacità di invaso superiore ai 20 Mmc non produce ulteriori benefici in termini di volume potabilizzato. È stata, infine, condotta un’analisi costi-benefici con l’obiettivo di valutare il risparmio di costi di esercizio derivante dai volumi sottratti alle fonti locali, a parità di richiesta complessiva a valle della rete. I risultati mostrano che, nell’ipotesi di serbatoio più grande, è possibile ottenere un risparmio di costi di esercizio per la potabilizzazione dalle fonti locali di circa l’11% a fronte di una spesa per l’aumento dei volumi potabilizzati da Ridracoli di circa il 4%.

Abstract:

Security Transaction taxes have been in place in many countries for many years now. Yet we do not fully know how these taxes effect prices, volumes, bid-ask spreads and volatility and in turn if they are good for the economy or not. This paper is an attempt to understand how security transaction taxes decrease volume of trading, decrease prices of stocks and increase bid-ask spreads. It analyses the effect the STTs implemented by the state and federal government in New York on June 1st 1905 and December 1st 1914 respectively, had on the stocks of the New York Stock Exchange. These results will help us analyze whether future implementations of STTs will harm or benefit the market.

Abstract:

Il controllo in agricoltura delle malattie causate da patogeni fungini può essere effettuato attraverso l’uso di modelli di previsione che si basano comunemente sul monitoraggio in tempo reale di una serie di variabili di input. Queste informazioni generalmente combinano dati metereologici locali con modelli matematici costruiti allo scopo di predire il rischio di malattie. Il processo decisionale si attiva quando un avvertimento sul potenziale rischio viene riconosciuto da parte dei modelli. Diversi modelli epidemiologici sono stati sviluppati e validati nel mondo. Negli Stati Uniti d’America, ad esempio, l’università della California ha sviluppato un supporto decisionale on-line per gestire la coltura secondo i principi della lotta integrata (Integrated Pest Management - IPM). Ciascun agricoltore può consultare il proprio database informativo e prendere decisioni sui trattamenti da effettuare basandosi su dati sito-specifici. Le difficoltà sorgono quando non sono disponibili dati meteorologici da stazioni poste nelle vicinanze del sito in studio o per le zone montane caratterizzate da una forte variabilità altimetrica. Inoltre i dati meteorologici disponibili possono presentarsi in formato non adeguato rispetto alle esigenze del modello previsionale. Con l’intento di avere una visione regionale e una maggiore accuratezza nella gestione del controllo delle malattie, l’obiettivo della tesi è stato l’utilizzo contemporaneo di modelli epidemiologici (Lobesia botrana e Erysiphe necator, agente causale dell’oidio della vite) con modelli fenologici (cultivar di vite Chardonnay) utilizzando parametri meteorologici come la temperatura per creare mappe a livello regionale, a frequenza giornaliera e con una risoluzione spaziale di 200 metri. L’utilizzo contemporaneo di entrambi i modelli aiuta ad essere più precisi nel consigliare interventi colturali nel periodo di sensibilità dell’ospite nei confronti del patogeno o della malattia in modo da poterne stimare il reale rischio di diffusione o insorgenza. Dopo aver calibrato e validato i modelli in Trentino-Alto Adige (Nord Italia) con dati metereologici locali, basandoci sul modello del cambiamento climatico HadAM3 dell’Hadley Centre (Pope et al., 2000),l’andamento climatico previsto è stato proiettato e statisticamente portato. in scala, utilizzando lo scenario A2 e B2. L’algoritmo statistico utilizzato per ridurre la scala giornaliera di risoluzione è chiamato “transfer function” (Eccel et al., 2009). Per completare l’analisi, è stato inoltre utilizzato lo scenario ridimensionato di ENSEMBLES attraverso l’uso di set di dati provenienti da 49 stazioni meteorologiche della FEM e dal pacchetto “RMAWGEN” (Cordano et al., 2012) creato con il software statistico R. (Gentleman et al., 1997). Per mappare i modelli è stata sviluppata una semplice piattaforma modulare WEB-GIS chiamata ENVIRO. I moduli sono “Open Source” e seguono gli standard internazionali dell’“Open Geospatial Consortium” (OGC) e sono stati implementati come segue: i) enviDB è il database per i dati spazio-temporali, ii) enviGRID permette agli utenti di navigare attraverso i dati e i modelli nello spazio e nel tempo, iii) enviMapper è l’interfaccia web per prendere le decisioni, consiste in uno stato dell’arte per mappare la vulnerabilità del cambiamento climatico a diverse scale di aggregazione nello spazio e nel tempo, iv) enviModel è l’interfaccia web per i ricercatori a cui viene fornita una piattaforma per processare e condividere modelli di rischio ambientali utilizzando il “web processing Technologies” (WPS) seguendo gli standard OGC. Con l’obiettivo di diventare ancora più accurati nelle previsioni dei volumi per i trattamenti contro insetti e malattie, in accordo con la direttiva 2009/128/EC, il seguente lavoro dimostra che il sensore LIDAR può essere utilizzato per caratterizzare la geometria della pianta della vite e stimare l’area fogliare (LAI) ad ogni stadio di crescita. Inoltre permette di calcolare il volume da applicare (Tree Row Volume -TRV) visualizzato nelle mappe 3D in GRASS. (Neteler et al., 2008, Neteler et al., 2012). Control of agricultural pests and diseases is often based on forecasting models commonly based on real time monitoring of inputs variables. This information generally combines meteorological local databases and mathematical models designed to forecast pest and disease risk. The decision process starts when an alert or a potential risk event from the outputs of the models is issued. Epidemiological models based on local datasets have been created and validated worldwide, for example in USA, the University of California developed the online Integrated Pest Management (IPM) program where each farmer can consult with his own database and make the pest management decision based on site-specific conditions. Difficulties arise when no data from a close weather station are available, in mountain areas where weather conditions highly depend on the altimetry, or if data are not in a standard format to feed the model. In a view of having a regional vision and an increased accuracy in the pest control management, the goal of this thesis was to run contemporaneously epidemiological (the pest Lobesia botrana and the pathogen causing Powdery mildew Erysiphe necator) and phenological models (grapevine cv. chardonnay) using environmental variables as temperature and to create maps at regional level, with 200 meters of resolution and daily scale or frequency. Running both models together helps to be more precise in the sensibility period of the host versus the pest or the disease and to understand the real final risk. After calibrating and validating the models in the Trentino-Alto Adige Region (Italy) with local weather data, the forecasted climate was projected and statistically downscaled, based on the output of the Hadley Centre climate model - HadAM3 (Pope et al., 2000) under scenarios A2 and B2. The statistical downscaling algorithm was “transfer function method” (Eccel et al., 2009) at daily resolution. In order to complete the analysis, the downscaled scenario from ENSEMBLES was also used with the datasets of 49 weather stations from FEM and the “RMAWGEN” packages (Cordano et al., 2012) created for this project in R statistical open source software (Gentleman et al., 1997). In order to map the models, a friendly modular WEB-GIS platform called ENVIRO was developed. Modules are Open Source, follow international Open Geospatial Consortium (OGC) standards and were implemented as follows: i) enviDB is the database for spatial temporal data, ii) enviGRID allows users to navigate through data and model in space and time, iii) enviMapper is the web interface for decision makers, a state of the art client to map vulnerability to climate change at different aggregation scales in time and space; finally, iv) enviModel is the web interface for researchers that provides a platform to process and share environmental risk models using web geo-processing technologies (WPS) following OGC standards. With the aim of being even more accurate in pests and diseases spraying volumes and according with the Directive 2009/128/EC, the current work shows that the LIDAR sensor can be used to characterize the geometry of the grapevine and the Leaf Area Index (LAI) at each growth stage and calculate the Tree Row Volume (TRV) visualized in 3D maps in GRASS (Neteler et al., 2008, Neteler et al., 2012).

Abstract:

Nel presente elaborato si tratta il fenomeno dei prestiti linguistici, della loro influenza all'interno della lingua italiana e in particolar modo l'importante ruolo che essi hanno nel linguaggio della moda. Tale analisi è resa possibile grazie alla traduzione del capitolo del New Look tratta dall'opera Christian Dior vu par Vogue di Charlotte Sinclair. Il volume appena citato è una traduzione del libro originale scritto in lingua inglese: Vogue on Dior di Charlotte Sinclair. Trattandosi di una traduzione, vengono prese in considerazione, oltre a quella originale, le versioni in italiano e in francese. Nel secondo capitolo infatti, oltre a fare qualche accenno alla Maison Dior e alla rivista Vogue, vengono esaminate le principali differenze a livello grafico ed editoriale dei tre volumi. In seguito, sono presentate le distinzioni relative al capitolo sottoposto alla traduzione, riservando una particolare attenzione ai prestiti adoperati nelle tre opere. Nell'ultimo capitolo infine, viene presentata la mia traduzione relativa al capitolo del New Look, analizzando le principali difficoltà riscontrate ,giustificando le scelte traduttive e confrontandole con la versione italiana già pubblicata.

Abstract:

This research project on volcanic debris avalanches aims to provide a better understanding of the influence of the volume, fall height and topography on the deposit location and morphology. This will enable improvements in delineation of the areas at risk from volcanic debris avalanches, and improvements in management of a disaster should it occur. Undertaken to fulfil the requirements for a double degree (Geological Engineering and MSc in Hazard and Disaster Management) this work is the result of a collaboration between Polytechnic Institute LaSalle-Beauvais in France and the University of Canterbury in New Zealand. Following a brief introduction to the topic, statistical analyses of volcanic debris avalanche deposits are undertaken. Multiple variables analyses (Principal Components Analyses and Regressions) were carried out using a database of 298 volcanic debris avalanches derived from modification of Dufresne’s recent database. It was found that the volume has the main influence on the deposits rather than the fall height; the latter seems to have greater effect on avalanches of small volume. The topography into which the deposit is emplaced mainly determines its geometrical characteristics. These statistical results were compared with the results of laboratory-scale analogue modelling. A model similar to that used by Shea in 2005 provided data indicating similar trends of the influence of volume, fall height and topography on mass movement deposits at all scales. The final aspect of this project was a numerical simulation of a large debris avalanche from the north flank of the Taranaki volcano in the direction of the city of New Plymouth. The numerical code VolcFlow developed by Kelfoun in 2005 was used, after being tested against the laboratory experiments to verity its accuracy. The simulations showed that the Pouaki range protects the city of New Plymouth form major impacts from Taranaki collapses, but also indicated some potential problems with the hazard zoning and evacuation zones presently in place.

Abstract:

La simulazione rappresenta una "alternativa” alla pratica reale per poter sperimentare concretamente quanto appreso dai libri, in particolare gli aspetti inusuali e potenzialmente pericolosi. Nell’apprendimento della pratica clinica, sta diventando rilevante l’uso di simulatori, dispositivi di simulazione medica progettati per imitare parti di pazienti, regioni anatomiche o attività cliniche. Il lavoro, svolto in collaborazione con l’azienda Accurate S.r.l. di Cesena, ha riguardato l’implementazione di alcuni miglioramenti al simulatore ecografico VausSim (Versatile Advanced Ultrasound Simulator), sviluppato dall’azienda stessa. Il dispositivo è dotato, oltre che di sonde ecografiche fittizie, di 20 tag RFID, solitamente posti sotto la pelle di un manichino in corrispondenza delle zone anatomiche da ecografare; ad ogni tag è associato un codice univoco, che letto dalla sonda, permette di simulare visualizzazioni ecografiche in funzione dell’orientamento della sonda. Lo scopo del lavoro si è concentrato su due aspetti. 1)Sviluppo di un metodo per la rappresentazione del corretto orientamento della sonda nello spazio 3D. La convenzione mediante angoli di Eulero di cui faceva uso il VausSim presentava il fenomeno del Gimbal Lock, con conseguente errata rilevazione dell’orientamento. La soluzione di tale problema è stata ottenuta passando ad una rappresentazione basata su conversione in quaternioni. 2)Elaborazione dei dati rilevati dalla sonda in modo da visualizzare correttamente l’immagine ecografica al variare del suo orientamento. L’errata visualizzazione inizialmente presentata dal VausSim è stata corretta modificando l’assegnamento del valore degli angoli di Eulero in fase di calibrazione, e ottenendo il corretto quaternione corrispondente. È inoltre proposta una soluzione alternativa, che consiste, anziché nell’interpolare immagini, nel creare un volume a partire dal set di immagini e successivamente tagliare tale volume in funzione dell’orientamento della sonda.

Abstract:

La Nuova generazione di impianti di produzione è favorita dalla quarta rivoluzione industriale che digitalizza i processi di produzione e assemblaggio. In questo contesto, le tecniche di misurazione sono uno dei principali candidati per l'applicazione di queste nuove tecnologie a causa del tempo, dei costi e delle competenze necessarie per analizzare le attività di produzione manuale e considerando la limitata precisione degli approcci tradizionali. Questa tesi propone un nuovo approccio softwaristico dedicato all'analisi del movimento e del tempo delle attività svolte da operatori umani all'interno di qualsiasi tipo luogo di lavoro industriale. L’attività infatti, valuta il lavoratore in un ambiente 3D considerando la sua interazione con il luogo di lavoro industriale attraverso la definizione di volumi di controllo appropriati all'interno del layout. I dati vengono elaborati dal software Matlab per misurare automaticamente e quantitativamente il contenuto del lavoro delle attività considerate attraverso un'accurata analisi del movimento e del tempo. L’obiettivo della tesi è stato quello di fornire un programma che sia in grado di estrapolare attraverso un’analisi dettagliata e puntuale dei dati raccolti, informazioni aggiuntive in modo automatico ai fini di produrre un continuo miglioramento nelle operazioni di picking e di assemblaggio.

Abstract:

Dans cette Thèse de Doctorat, nous nous intéressons à deux problématiques: (i) le développement de stratégies de stabilisation pour des méthodes de type discontinuous Galerkin (DG) appliquées à des écoulements shallow-water fortement non-linéaires, (ii) le développement d'une stratégie de modélisation et de simulation numérique des interactions non-linéaires entre les vagues et un objet flottant en surface, partiellement immergé. Les outils développés dans le cadre du premier axe de travail sont mis à profit et valorisés au cours de la deuxième partie.Les méthodes de discrétisation de type DG d'ordre élevé présentent en général des problèmes de robustesse en présence de singularités de la solution. Ces singularités peuvent être de plusieurs natures: discontinuité de la solution, discontinuité du gradient ou encore violation de la positivité de la hauteur d'eau pour des écoulements à surface libre. Nous introduisons dans la première partie de ce manuscript deux approches de type Finite-Volume Subcells permettant d'apporter une réponse à ces problèmes de robustesse. La première approche repose sur une correction a priori du schéma DG associée à un limiteur TVB et un limiteur de positivité. La seconde approche s'appuie quant à elle sur une correction a posteriori permettant d'identifier avec une meilleure précision les cellules incriminée, ainsi que sur les propriétés de robustesse inhérentes au schéma Volumes-Finis limite d'ordre un. Cette seconde approche permet d'assurer la robustesse du schéma DG initial en présence de discontinuité, ainsi que la positivité de la hauteur d'eau, tout en préservant une excellente qualité d'approximation, bénéficiant d'une résolution de l'ordre de la sous-maille. De façon préliminaire, cette seconde approche est également étendue au cas de la dimension deux d'espace horizontal. De nombreux cas-test permettent de valider cette approche.Dans la seconde partie, nous introduisons une nouvelle stratégie numérique conçue pour la modélisation et la simulation des interactions non linéaires entre les vagues en eau peu profonde et un objet flottant partiellement immergé. Au niveau continu, l'écoulement situé dans le domaine extérieur est globalement modélisé par les équations hyperboliques non-linéaires de Saint-Venant, tandis que la description de l'écoulement sous l'objet se réduit à une équation différentielle ordinaire non linéaire. Le couplage entre l'écoulement et l'objet est formulé comme un problème au bord, associé au calcul de l'évolution temporelle de la position des points d'interface air-eau-objet. Au niveau discret, la formulation proposée s'appuie sur une approximation DG d'ordre arbitraire, stabilisée à l'aide de la méthode de correction locale des sous-cellules (a posteriori) introduite dans la première partie. L'évolution temporelle de l'interface air-eau-objet est calculée à partir d'une description Arbitrary Lagrangian-Eulerian (ALE) et d'une transformation appropriée entre la configuration initiale et celle dépendant du temps. Pour n'importe quel ordre d'approximation polynomiale, l'algorithme résultant est capable de: (1) préserver la loi de conservation géométrique discrète (DGCL), (2) garantir la préservation de la positivité de la hauteur d'eau au niveau des sous-cellules, (3) préserver la classe des états stationnaires au repos (well-balancing), éventuellement en présence d'un objet partiellement immergé.Plusieurs validations numériques sont présentées, montrant le caractère opératoire de cette approche, et mettant en évidence que le modèle numérique proposé: (1) permet effectivement de modéliser les différents types d'interactions vague / objet flottants, (2) calcul efficacement l' évolution temporelle des points de contact air-eau-objet et redéfinit en conséquence le nouveau maillage grâce à la méthode ALE, (3) gère avec précision et robustesse les possibles singularités de l'écoulement, (4) préserve la haute résolution des schémas DG au niveau des sous-cellules In this Ph.D., we investigate two main research problems: (i) the design of stabilization patches for higher-order discontinuous-Galerkin (DG) methods applied to highly nonlinear free-surface shallow-water flows, (ii) the construction of a new numerical approximation strategy for the simulation of nonlinear interactions between waves in a free-surface shallow flow and a partly immersed floating object. The stabilization methods developed in the first research line are used in the second part of this work.High-order discontinuous-Galerkin (DG) methods generally suffer from a lack of nonlinear stability in the presence of singularities in the solution. Such singularities may be of various kinds, involving discontinuities, rapidly varying gradients or the occurence of dry areas in the particular case of free-surface flows. In the first part of this work, we introduce two new stabilization methods based on the use of Finite-Volume Subcells in order to alleviate these robustness issues. The first method relies on an a priori limitation of the DG scheme, together with the use of a TVB slope-limiter and a PL. The second one is built upon an a posteriori correction strategy, allowing to surgically detect the incriminated local subcells, together with the robustness properties of the corresponding lowest-order Finite-Volume scheme. This last strategy allows to ensure the nonlinear stability of the DG scheme in the vicinity of discontinuities, as well as the positivity of the discrete water-height, while preserving the subcell resolution of the initial scheme. This second strategy is also preliminary investigated in the two dimensional horizontal case. An extensive set of test-cases assess the validity of this approach.In the second part, we introduce a new numerical strategy designed for the modeling and simulation of nonlinear interactions between surface waves in shallow-water and a partially immersed surface piercing object. At the continuous level, the flow located in the textit{exterior} domain is globally modeled with the nonlinear hyperbolic shallow-water equations, while the description of the flow beneath the object reduces to a nonlinear ordinary differential equation. The coupling between the flow and the object is formulated as a free-boundary problem, associated with the computation of the time evolution of the spatial locations of the air-water-body interface. At the discrete level, the proposed formulation relies on an arbitrary-order discontinuous Galerkin approximation, which is stabilized with the a posteriori Local Subcell Correction method through low-order finite volume scheme introduced in the first part. The time evolution of the air-water-body interface is computed from an Arbitrary-Lagrangian-Eulerian (ALE) description and a suitable smooth mapping between the original frame and the current configuration. For any order of polynomial approximation, the resulting algorithm is shown to: (1) preserves the Discrete Geometric Conservation Law, (2) ensures the preservation of the water-height positivity at the subcell level, (3) preserves the class of motionless steady states (well-balancing), possibly with the occurrence of a partially immersed object.Several numerical computations and test-cases are presented, highlighting that the proposed numerical model(1) effectively allows to model all types of wave / object interactions, (2) efficiently provides the time-evolution of the air-water-body contact points and accordingly redefine the new mesh-grid thanks to ALE method (3) accurately handles strong flow singularities without any robustness issues, (4) retains the highly accurate subcell resolution of discontinuous Galerkin schemes

Syftet med denna uppsats är att ur ett genusvetenskapligt perspektiv undersöka hur svenska kvinnliga hiphop artister uttrycker positioner rörande femininitet, sexualitet och klass i låttexter. Undersökningen är gjord utifrån en kritisk diskursanalys på åtta utvalda låttexter från musikåret 2014 och fokus ligger uteslutande på låttexter framförda av kvinnliga rappare. De teoretiska utgångspunkterna för undersökningen grundar sig i Beverley Skeggs teori om respektabilitet, där både klass och genus är centrala teman. Analysen visar hur rapparna gör motstånd mot sociala och moraliska normer kring klass, femininitet och sexualitet och på så sätt dissimilerar de inte en klasstillhörighet som Skeggs menar att en kan göra för att uppnå legitimitet. Texterna uttrycker istället en positiv identifikation med arbetarklassen och försöker därmed uppnå legitimitet genom identifikation, inte genom att dissimilera en klassposition. Analysen visar också att rapparna kan inta en maskulin position, dels för att motsätta sig en femininitetsdiskurs, men även för att kunna rappa om sexualitet med makt.

Abstract:

Il presente lavoro di ricerca indaga il significato e i contorni assunti dal concetto di sfruttamento nel diritto penale italiano, vagliando in particolare la possibilità di attribuire rilevanza autonoma a una nozione di sfruttamento (definita in “senso stretto”) caratterizzata dalla presenza del consenso della vittima. A tal fine, vengono fatti oggetto di specifica attenzione – alla luce di un’analisi della dottrina e della giurisprudenza nazionali e sovranazionali – i concetti di “vulnerabilità” e di “approfittamento/abuso dell’altrui condizione di vulnerabilità”, considerati centrali per definire il disvalore dei fatti di sfruttamento dell’essere umano e per giustificare l’irrilevanza del consenso prestato dalla vittima al proprio sfruttamento; la ricerca conduce inoltre un’analisi critica delle posizioni emerse in dottrina e in giurisprudenza con riferimento al settore della normativa oggetto di esame, suggerendo alcune soluzioni coerenti con il modello interpretativo proposto. In conclusione al lavoro, la possibilità di attribuire rilevanza penale nel nostro sistema giuridico allo sfruttamento consensuale dell’individuo viene confrontata con i principi cardine dell’ordinamento (legalità, offensività, sussidiarietà e proporzione, effettività), da cui si ricavano indicazioni de iure condito e de iure condendo. The research investigates the meaning and the scope of the concept of exploitation in Italian criminal law, particularly by addressing if a notion of exploitation characterized by the presence of the victim's consent (that we call “strictly speaking” exploitation) has an autonomous relevance in this legal field. Therefore, the research – in the light of an analysis of national and supranational doctrine and jurisprudence – focuses on the concepts of "vulnerability" and “taking advantage/abuse of others' condition of vulnerability", which are pivotal to define the disvalue of the human exploitation and to justify why the consent given by the victim to her/his exploitation can be considered irrelevant; it also analyzes critically the different positions emerged in doctrine and jurisprudence in this field, suggesting some solutions consistent with the proposed interpretative model. The criminal relevance of consensual exploitation is then compared with the principles of the Italian legal system (legality, offensiveness, subsidiarity and proportion, effectiveness).

Abstract:

La Multifragmentation du système nucléaire formé dans les collisions centrales Xe+Sn entre 32 et 50 MeV/A est étudiée avec le multidétecteur INDRA. Une analyse tensorielle permet la sélection des collisions centrales. Une proportion importante de la charge (environ 85 %) est émise isotropiquement, ce qui indique qu'un degré d'équilibration élevé est atteint. Les partitions de charges sont caractéristiques d'un régime de production multiple de fragments. La forme des distributions en énergie cinétique des fragments, ainsi que celle des fonctions de corrélation en vitesse réduite indiquent que la fragmentation est simultanée et se produit à une densité plus faible que la densité de saturation. La comparaison des données expérimentales avec les prédictions du modèle de multifragmentation statistique de Copenhague (SMM), permet de montrer que les partitions de charges sont compatibles avec l'hypothèse d'un équilibre thermodynamique, alors que les variables cinématiques sont plus contraignantes et difficiles à reproduire conjointement. Les fonctions de corrélations entre fragments permettent de contraindre le volume de freeze-out et d'estimer la part de l'énergie emmagasinée sous forme collective radiale. A 50 MeV/A, le volume de freeze-out est estimé à 2 .7 fois le volume correspondant à la densité de saturation. Il diminue avec l'énergie incidente et peut atteindre des valeurs de l'ordre de 2 fois le volume de saturation à 32 MeV/A. L'énergie collective varie de 0 à 1.3 MeV/A quand l'énergie incidente augmente. Elle n'est pas purement thermique et est probablement due à une phase de compression développée lors des premiers instants de la collision.
