Повний текст джерелаThe objective of this thesis is to model matrix-valued time series in a high-dimensional framework. To this end, the entire study is presented in a non-asymptotic framework. We first provide a test procedure capable of distinguishing whether the covariance matrix of centered random vectors with centered stationary distribution is equal to the identity or has a sparse Toeplitz structure. Secondly, we propose an extension of low-rank matrix linear regression to a regression model with two matrix-parameters which create correlations between the rows and he columns of the output random matrix. Finally, we introduce and estimate a dynamic topic model where the expected value of the observations is factorizes into a static matrix and a time-dependent matrix following a simplex-valued auto-regressive process of order one

Повний текст джерелаObjectives: To assess the effect of epidural analgesia on sonographic progression of fetal head in second stage of labor. Methods: Nulliparous low-risk women at term (37+0-42+0) attending the labor ward of our University Hospital were recruited for the purpose of this study. A volume dataset was acquired by translabial ultrasound every 20 minutes from the beginning of the active second stage until delivery. A series of sonographic parameters were derived from offline analysis of each volume (angle of progression, progression distance, head symphysis distance and midline angle). All parameters were compared at each time interval between patients with or without elective epidural at the onset of labor. Results: 71 patients were recruited in the study; 41 (57.7%) of them in the epidural group. Spontaneous vaginal delivery was achieved in 58 (81.7%) cases. Vacuum delivery and Cesarean section were performed in 8 (11.3%) and 5 (7.0%) cases, respectively. All ultrasound parameters values were comparable at each time interval in the epidural and non-epidural group. Conclusions: Fetal head progression, longitudinally assessed by three-dimensional ultrasound, seems to be comparable in patients submitted or not to epidural administration.

The Canadian Arctic is facing a set of compounding crises that will drastically impact the future of its coastal frontier. At a time when climate change is having a detrimental impact on the Arctic landscape, Northern communities are on the frontline of resource development where industrial money promises major territorial and social change. In this way, the Inuvialuit population of Tuktoyaktuk will find opportunity in crisis as they strategically manipulate both the agendas of the petroleum industry as well as the federal government's own incentive for Northern development in order to construct a new coastal frontier and secure a post-oil economy defended from the rising sea. This form of oil urbanization provides an architectural and infrastructural imperative for this thesis, as change will occur rapidly and at a much larger scale than these communities could spark or manage on their own. The Tuktoyaktuk landscape will undoubtedly become transformed by the creation of occupiable, defensive infrastructure that secures new land on which to reimagine the arctic dwelling and its temporal interface with a rising sea and a changing economy. Mobilized by the demands and goals of the Inuvialuit population, this thesis examines Tuktoyaktuk as an exemplary model for strategic modernization and development of remote Arctic communities on the frontline of industrialization. The goal of designing this enhanced urban structure is to make use of the finite economic opportunity to set up the framework from which the community will thrive and grow upon the retreat of the oil operations. By maximizing the opportunities that emerge from these complexities of place, we begin to unveil a unique and timely moment for architectural and infrastructural innovation.

The behavior of alloy 617 at 650°C in low oxygen partial pressure environments has been studied under static loading. Of particular interest was the crack growth rate in these conditions. For that, tests were conducted at a constant stress intensity factor of 49.45 MPa'm (45 ksidinch) using a direct current potential drop measurement system to determine crack length. High purity argon gas allowed establishing an oxygen partial pressure as low as 10-22 atm and premixed oxygen/argon gases were used to vary the oxygen potential. To go dee er into the understanding of the phenomena involved, a creep test (constant load of 1.21x10 N in argon environment) and a corrosion experiment (50 ppm oxygen in argon for 500 hours without any load) were also added. The crack growth tests led to a particularly unexpected result: whatever the oxygen potential, the crack growth rate increased with time and the plot for the crack length versus time displayed a recurrent parabolic shape without any change in the environment. No unique crack growth rate could be defined in a given environment and the influence of the environment on the crack growth rate was not clearly visible. Multiple features were found to surround the main crack: secondary cracks parallel to the principal one, intergranular cracking ahead of the crack tip, wedge cracks at grain boundaries and aggregates of Cr-rich carbides near the lips of the crack. Moreover no extensive oxide scale was formed on the surface of the sample exposed to the corrosive environment (50 ppm oxygen in argon) for 500 hours. The non-constant crack growth rates, together with the observed cracking features, were attributed to the competition between creep deformation and mechanical fracture, likely environmentally enhanced. An exponential law was found to fit the data for the crack growth rate as a function of time for a K of 49.45 MPalm (45 ksi'inch). The effects of the environment were overcome by mechanical and thermal processes leading to damage accumulation and so, a reaction of alloy 617 to the external stress and temperature highly dependent on time. This behavior was compared with the one of alloys Haynes 230 and Incoloy 908 in the same conditions.

This monograph studies the theory of information through the multiuser secret key agreement problem. A general notion of mutual dependence is established for the secrecy capacity, as a natural generalization of Shannon's mutual information to the multivariate case. Under linear-type source models, this capacity can be achieved practically by linear network codes. In addition to being an unusual application of the network coding solution to a secrecy problem, it gives secrecy capacity an interpretation of network information flow and partition connectivity, further confirming the intuitive meaning of secrecy capacity as mutual dependence. New identities in submodular function optimization and matroid theory are discovered in proving these results. A framework is also developed to view matroids as graphs, allowing certain theory on graphs to generalize to matroids. In order to study cooperation schemes in a network, a general channel model with multiple inputs is formulated. Single-letter secrecy capacity upper bounds are derived using the Shearer-type lemma. Lower bounds are obtained with a new cooperation scheme called the mixed source emulation. In the same way that mixed strategies may surpass pure strategies in zero-sum games, mixed source emulation outperforms the conventional pure source emulation approach in terms of the achievable key rate. Necessary and sufficient conditions are derived for tightness of these secrecy bounds, which shows that secrecy capacity can be characterized for a larger class of channels than the broadcast-type channels considered in previous work. The mixed source emulation scheme is also shown to be unnecessary for some channels while insufficient for others. The possibility of a better cooperative scheme becomes apparent, but a general scheme remains to be found.

Cells are constantly bombarded with stimuli that they must sense, process, and interpret to make decisions. This capability is provided by interconnected signaling pathways. Many of the components and interactions within pathways have been identified, and it is becoming clear that the precise dynamics they generate are necessary for proper system function. However, our understanding of how pathways are interconnected to drive decisions is limited. We must overcoming this limitation to develop interventions that can fine tune a cell decision by modulating specific features of its constituent pathway's dynamics. How can we quantatively map a whole cell decision process? Answering this question requires addressing challenges at three scales: the detailed biochemistry of protein-protein interactions, the complex, interlocked feedback loops of transcriptionally regulated signaling pathways, and the multiple mechanisms of connection that link distinct pathways together into a full cell decision process. In this thesis, we address challenges at each level. We develop new computational approaches for identifying the interactions driving dynamics in protein-protein networks. Applied to the cyanobacterial clock, these approaches identify two coupled motifs that together provide independent control over oscillation phase and period. Using the p53 pathway as a model transcriptional network, we experimentally isolate and characterize dynamics from a core feedback loop in individual cells. A quantitative model of this signaling network predicts and rationalizes the distinct effects on dynamics of additional feedback loops and small molecule inhibitors. Finally, we demonstrated the feasibility of combining individual pathway models to map a whole cell decision: cell cycle arrest elicited by the mammalian DNA damage response. By coupling modeling and experiments, we used this combined perspective to uncover some new biology. We found that multiple arrest mechanisms must work together in a proper cell cycle arrest, and identified a new role for p21 in preventing G2 arrest, paradoxically through its action on G1 cyclins. This thesis demonstrates that we can quantitatively map the logic of cellular decisions, affording new insight and revealing points of control.

The environmental cues for synchronous reproduction were investigated for two highly abundant, ecologically important crustacean species: the temperate acorn barnacle, Semibalanus balanoides, and the tropical terrestrial crab, Gecarcinus quadratus. Larval ecology of these two species was also studied to determine potential sources of larval mortality and recruitment success. High-frequency observations revealed that early-stage larval abundance of S. balanoides was related to storms, and possibly turbidity. Field observations and experiments studied the effect of turbidity and phytoplankton on larval release response. Release coincided with increased turbidity at three sites along the northeast coast of the United States. A three-year time series of phytoplankton and zooplankton data showed that larval release was not consistently related to phytoplankton abundance (total or single species). When gravid barnacles were exposed to phytoplankton or synthetic beads, they released in response to both, suggesting that presence of particles is more important than identity of particles. Feeding experiments showed that adult cannibalism on newly released larvae is lower in highly turbid conditions. It is suggested here that S. balanoides synchronizes its reproduction with the onset of phytoplankton blooms, but turbidity may fine-tune the timing if it provides predation refuge for larvae. Adult G. quadratus females undertake synchronized breeding migrations to the ocean after the first rains of the rainy season, presumably when the risk of desiccation is lowest. They wait for darkness and an ebbing tide before releasing their eggs into the water. First-stage zoeas have dark pigmentation, long dorsal and rostral spines, and a pair of lateral spines. Hatching in darkness may help zoeas avoid predation from planktivorous diurnal fish, and the zoeal spines may deter predation from planktivorous nocturnal fish. In the laboratory, a G. quadratus zoea reached the megalopa stage in 21 days. A mass migration of megalopae and juveniles out of the water was observed 30 days after adult females released their eggs. Plankton pump samples taken near the island suggest that zoea abundance and distribution may be related to the phase of the internal tide. Synchronous reproduction in these two species appears to be the result of predator avoidance behaviors.

The Light Force Accelerometer (LFA) is an optical inertial sensor in which radiation pressure from two counter-propagating laser beams optically confines a glass microsphere. Inertial acceleration of the device results in microsphere displacement along the sensitive axis, which is subsequently nulled by optical forces to provide an acceleration measurement. A simple calculation that takes into account fundamental noise processes in the LFA (i.e., shot noise and RIN in the laser beams) places the sensitivity limit of this accelerometer at < 100 ng. By incorporating widely available, inexpensive optical components into a simple design, a high-precision LFA could provide an appealing alternative to other sensors of comparable performance. Previous work on the LFA revealed instabilities in proof mass position detection caused by the asphericity of microspheres. In this thesis, an alternative method for position detection which was less sensitive to shape-irregularities in microspheres was investigated. Results indicated that resolution of microsphere motion was enhanced significantly when the new detection method was implemented. This improvement. however, did not eliminate the position instabilities observed previously. Capabilities for optical trapping with two counter-propagating beams in air were also developed in this work. Trapping with feedback position control in air was demonstrated for the first time, but long-term trapping in vacuum was prohibitively difficult due to destabilizing mechanical vibrations. For a microsphere in atmospheric pressure, the estimated bias stability was 318 jig after 300 seconds of averaging, and the approximate short-term sensitivity was 500 pg/v/ Hz. Stabilization of mechanical vibrations and precise calibration of power measurements to acceleration will allow this two-beam trap to probe the performance limits of the LFA.

With over 230,000 hours of audio/video recordings of a child growing up in the home setting from birth to the age of three, the Human Speechome Project has pioneered a comprehensive, ecologically valid observational dataset that introduces far-reaching new possibilities for the study of child development. By offering In vivo observation of a child's daily life experience at ultra-dense, longitudinal time scales, the Speechome corpus holds great potential for discovering developmental insights that have thus far eluded observation. The work of this thesis aspires to enable the use of the Speechome corpus for empirical study of emotional factors in early child development. To fully harness the benefits of Speechome for this purpose, an automated mechanism must be created to perceive the child's emotional state within this medium. Due to the latent nature of emotion, we sought objective, directly measurable correlates of the child's perceived emotional state within the Speechome corpus, focusing exclusively on acoustic features of the child's vocalizations and surrounding caretaker speech. Using Partial Least Squares regression, we applied these features to build a model that simulates human perceptual heuristics for determining a child's emotional state. We evaluated the perceptual accuracy of models built across child-only, adult-only, and combined feature sets within the overall sampled dataset, as well as controlling for social situations, vocalization behaviors (e.g. crying, laughing, babble), individual caretakers, and developmental age between 9 and 24 months. Child and combined models consistently demonstrated high perceptual accuracy, with overall adjusted R-squared values of 0.54 and 0.58, respectively, and an average of 0.59 and 0.67 per month. Comparative analysis across longitudinal and socio-behavioral contexts yielded several notable developmental and dyadic insights. In the process, we have developed a data mining and analysis methodology for modeling perceived child emotion and quantifying caretaker intersubjectivity that we hope to extend to future datasets across multiple children, as new deployments of the Speechome recording technology are established. Such large-scale comparative studies promise an unprecedented view into the nature of emotional processes in early childhood and potentially enlightening discoveries about autism and other developmental disorders.

Повний текст джерелаAbstract: Background The aetiology of weight loss in Alzheimer Disease (AD), has not yet been definitively established. Although appears multifactorial, a decline in food intake may be a contributor. Nutritional supplements are often prescribed, especially to prevention for weight loss, but it has not been demonstrated that a short-term nutritional supplementation has impact in AD-patients nutritional status. Objectives The aim of this study was (1) to evaluate the effect of short-term administration of a high protein, energy-dense Oral liquid Supplement (OS) in patients with mild AD who were malnourished, on nutritional status and in body composition, cognitive function and functional ability; (2) to assess the long-term effect of this intervention after discontinuation of the OS. Methods and Measurements A 21 days prospective randomized nonblinded controlled trial was conducted in a Geriatric Unit of a Psychiatric Hospital. From an initial group of Thirty five patients, twenty were randomly assigned to the Treatment Group (TG) n=20 and Fifteen to the Control Group (CG) n=15. During the study period, the TG received during 21 consecutive days, once a day a 200 mL high protein energy-dense OS, which provided 400kcal from a mixture of protein (18% of energy), fat (17.4% of energy), and carbohydrate (42.8% of energy) plus dietetic advice. Patients in the CG received the same dietetic advice as the TG, but no OS. The nutritional status, body composition, functional status and cognitive function were determined at baseline, 21 days (after intervention) and at 90 days of follow-up. The Mini Nutritional Assessment (MNA), anthropometric measurements, bioelectrical impedance analysis and serum biomarkers (albumin, total-protein, total-cholesterol, vitamin-B12 and folic acid) levels were obtained. Cognitive function was evaluated using the Mini Mental Status Examination (MMSE) tool and the Clock-Drawing Test (CDT). (...)

Повний текст джерела[ES] La variedad Bobal, mayoritaria en la Denominación de Origen Utiel-Requena, siempre se ha considerado como una variedad menos noble cara a la obtención de vinos tintos de calidad. El desarrollo de nuevas técnicas enológicas (microoxigenación, crianza sobre lias, adición de preparados experimentales de levaduras inertes) puede dar lugar a una mejora en la composición polifenólica de sus vinos y una mejor estabilidad en el tiempo y poder establecer un proceso de producción adecuado. Con ese fin se recogieron uvas de la variedad Bobal de la EVER de Requena (Diputación de Valencia) durante tres campañas, siendo elaboradas en la bodega del Centro de forma tradicional. Una vez finalizada la fermentación maloláctica se trasegó el vino limpio a una serie de envases para la experiencia, tanto de acero (veintisiete) como barricas (seis), Todas las experiencias se han realizado por triplicado. Tres depósitos de acero actuaron de testigos sin tratamientos; a tres se adicionó 10 % de las lías previamente extraídas; seis fueron sometidos a microoxigenación y tres de ellos además adicionados del 10 % de lías; en los quince restantes se adicionó cinco preparados diferentes de levaduras inertes comerciales. Todos los que contenían lías o preparados comerciales fueron removidos tres veces a la semana (batonage). De seis barricas de roble, en tres de ellas se mantuvieron de testigo y al resto se adicionó un 10% de lías previamente extraídas y se realizaron removidos tres días a la semana. Mensualmente se extrajeron muestras para determinar su composición polifenólica y su variación en el tiempo durante seis meses. Los resultados encontrados muestran que los vinos criados sobre lías y adicionados de levaduras secas inactivas presentaban baja astringencia, volumen en boca y sensación de untuosidad por el nivel de unión polisacárido-tanino, mientras que presentaban una mayor caída de color. La crianza en barrica con lías y la microoxigenación en presencia de lías favorecen el mantenimiento del nivel de polifenoles con baja astringencia y buen nivel del complejo polisacárido-tanino que incrementa la estructura y untuosidad de los vinos.
[CAT] La varietat Bobal, majoritària en la Denominació d'Origen Utiel-Requena, sempre s'ha considerat com una varietat menys noble cara a l'obtenció de vins negres de qualitat. El desenvolupament de noves tècniques enològiques (microoxigenación, criança sobre lies, addició de preparats experimentals de llevats inerts) pot donar lloc a una millora en la composició polifenòlica dels seus vins i una millor estabilitat en el temps i poder establir un procés de producció adequat. Amb aquesta finalitat es van recollir raïm de la varietat Bobal del camp d'experiències "Los Coloraos" de EVER de Requena (Diputació de València) durant tres campanyes, sent elaborades al celler del Centre de forma tradicional. Finalitzada la fermentació malolàctica es va trasbalsar el vi net a una sèrie d'envasos per a l'experiència, tant d'acer (vint-i-set) com bótes (sis), Totes les experiències s'han realitzat per triplicat. Tres dipòsits d'acer van actuar de testimonis sense tractaments; a tres es va addicionar 10% de les lías de ví prèviament extretes; sis van ser sotmesos a microoxigenación i tres d'ells a més addicionats del 10% de líes; en els quinze restants es va addicionar 5 preparats diferents de llevats inerts comercials. Tots els que contenien lías de ví o preparats comercials van ser remoguts tres vegades a la setmana (batonage). De sis bótes de roure, en tres d'elles es van mantenir de testimoni i la resta es va addicionar un 10% de lías de ví prèviament extretes i es van realitzar remoguts tres dies a la setmana. Mensualment es van extreure mostres per determinar la seva composició polifenòlica i la seva variació en el temps durant sis mesos. Els resultats mostren que els vins criats sobre lies i addicionats de llevats secs inactives presentaven baixa astringència, volum en boca i sensació d'untuositat pel nivell d'unió polisacàrid-taní, mentre que presentaven una major caiguda de color. La criança en bóta amb lies i la microoxigenación en presència de lies afavoreixen el manteniment del nivell de polifenols amb baixa astringència i bon nivell del complex polisacàrid-taní que incrementa l'estructura i untuositat dels vins.

Повний текст джерела[ES] A partir de un análisis centrado en los focos críticos, determinamos las direcciones y formalismos que el género cartográfico ha reivindicado en la figura del mapa, como dispositivo capaz de apuntalar propuestas disidentes a través del arte contemporáneo. La cartografía en la práctica artística, permite desdecir la representación única del mundo y borrar las líneas fronterizas de los territorios, convirtiéndose, de esta manera, en una herramienta no neutral imprescindible para transformar la realidad. En la presente investigación, la ciudad se torna escenario de tácticas, usos y prácticas, donde lo artístico abandona la idea del mapa eterno en favor de una cartografía versátil y dinámica, en la que el binomio social y político es indiscernible. Asimismo, se aborda la forma en que la cartografía es utilizada por los artistas y las artistas como dispositivo donde se debaten y discuten simbologías múltiples, para interpretar y traducir en formas visuales un discurso plural, eco de las demandas que las nuevas relaciones sociales interfieren sobre el territorio. Es en este escenario donde el artista asume nuevos roles, ligados a las figuras de mediador, detonador de acciones y facilitador de procesos, en una práctica que busca subvertir jerarquías, traspasar los límites impuestos y hacer visible una realidad hasta ahora suprimida o, al menos, que no había sido objeto de representación. Por último, se analiza cómo la cartografía ha contribuido al surgimiento de una nueva agencia política del territorio, que sustenta, entre otras implicaciones, el soporte organizativo de un cuerpo social -el de los colectivos y movimientos sociales- que carecían del instrumental necesario para subjetivarse en una esfera propia y que, mediante la cartografía, articulan un discurso plural desde el disenso, que promueve una transformación social contra el sistema de injusticias y recorte de libertades. En un ir y venir de la calle al píxel, del espacio público a la red digital y viceversa, surgen una serie de prácticas espaciales y poéticas contestatarias que, mediante la cartografía, prefiguran las condiciones de acción colectiva y constituyen un seña de identidad en el discurso artístico contemporáneo.
[CAT] A partir de l'anàlisi centrat en els focus crítics, determinem les direccions i formalismes que el gènere cartogràfic ha reivindicat en la figura del mapa, com dispositiu capaç d'apuntalar propostes dissidents a través de l'art contemporani. La cartografia a la pràctica artística permet desdiure la representació única del món i esborrar les línies frontereres dels territoris, convertint-se, d'aquesta manera, en una eina no neutral imprescindible per transformar la realitat. A la present recerca, la ciutat esdevé escenari de tàctiques, usos i practiques, on l'artístic abandona la idea del mapa etern, a favor d'una cartografia versàtil i dinàmica, en la que el binomi social i polític són indiscernibles. Així mateix, s'aborda la forma en la que la cartografia és usada pels artistes, com dispositiu on es debaten i discuteixen simbologies múltiples, per interpretar i traduir en formes visuals un discurs plural, que demanden les noves relacions socials que interfereixen sobre el territori. És en aquest escenari, on l'artista assumeix nous rols lligats a les figures de mediador, detonador d'accions i facilitador de procesos, en una pràctica que cerca subvertir jerarquies, trespassar els límits imposats i fer visible una realitat fins ara suprimida o, almenys, que no havia sigut objete de representació. Per últim, s'analitza com la cartografia ha contribuït al sorgiment d'una nova agència política del territori, que sustenta, entre d'altres implicacions, el soport organitzatiu a un cos social -el dels col.lectius i moviments socials-que mancaven dels instruments necessaris per subjectivar-se en una esfera pròpia, i que mitjançant la cartografia articulen un discurs plural des del dissens, que promou una transformació social envers el sistema d'injustícies i retallada de llibertats. En una anada i tornada del carrer al píxel, de l'espai públic a la xarxa digital i viceversa, sorgeixen una sèrie de pràctiques espacials i poètiques contestatàries, que mitjançant la cartografia prefiguren les condicions de l'acció col.lectiva i constitueixen un senyal d'identitat en el discurs artístic actual.

Повний текст джерела[ES] La performance es una práctica artística que forma parte de un grupo de técnicas que no pretenden crear un objeto, o su representación, como culminación del acto creador. Englobadas en un conjunto conocido como arte de acción, para éste el verdadero acto artístico se encuentra en la acción intencional del artista durante el proceso de creación. En su forma más pura, la performance debería prescindir de todo objeto para dar a entender su propuesta; sin embargo, el artista precisa determinados objetos en los que apoyar su discurso. Consideramos que entre éstos ocupan un lugar especial los elementos audiovisuales debido a la especial relación que han establecido con la performance. Objetivos: El estudio que proponemos busca identificar las relaciones de la performance con el medio audiovisual, puesto que consideramos que condensan y explican la evolución del Arte en los últimos cien años. Como objetivos particulares proponemos: - Un análisis comparativo que permita diferenciar los distintos tipos de performance. - Descubrir la evolución de la performance a tenor del desarrollo del medio audiovisual. - Establecer parámetros y elementos de análisis sobre las performances que utilizan los medios audiovisuales. - Realizar un estudio de las líneas de trabajo que se han establecido en la performance desde sus inicios (documentación, cámara fija como espectador, imagen alterada y su postproducción...) utilizando como línea argumental la relación entre el intérprete y la imagen audiovisual. - Analizar los límites internos entre los diferentes modos del arte de acción y los que éste mantiene con otras disciplinas artísticas. Metodología: Para lograr estos objetivos proponemos el análisis de una serie de acciones artísticas con valor performativo relacionadas con el medio audiovisual en uno u otro de los siguientes grados: 1. - Documentación: el primer uso que se hizo de los elementos audiovisuales fue el de la documentación, primero mediante la cámara fotográfica y luego con cámaras de cine y vídeo, que permitieron registrar la dimensión temporal de la acción. 2. - Interacción: la acción artística consiguió desarrolla su mensaje mediante el uso de elementos tecnológicos (sonido, música, autómatas, proyecciones de diapositivas o filmaciones, monitores de TV, etc.) 3. - Creación: la flexibilidad que otorga el medio videográfico y la sencillez de sus técnicas, posibilitaron que las técnicas narrativas adelantadas por el cine fueran asimiladas en una nueva práctica artística, la vídeoperformance. La investigación se ha estructurada en estos puntos, analizando distintas obras atendiendo a la presencia de alguna característica que permita encuadrarla en uno u otro. Resultados: De este análisis se han extraído conclusiones generales como son los límites variables de la práctica de la performance, su carácter híbrido al incorporar elementos físicos y expresivos dispares, la necesidad de documentar la acción y la importancia del tratamiento del elemento temporal y su relación con el tiempo de representación.

Objectius: L'estudi que proposem busca identificar les relacions de la performance amb el mitjà audiovisual, ja que considerem que condensen i expliquen l'evolució de l'Art en els últims cent anys. Com a objectius particulars proposem: - Una anàlisi comparativa que permeta diferenciar els distints tipus de performance. - Descobrir l'evolució de la performance a tenor del desenvolupament del mitjà audiovisual. - Establir paràmetres i elements d'anàlisi sobre les performances que utilitzen els mitjans audiovisuals. - Realitzar un estudi de les línies de treball que s'han establit en la performance des dels seus inicis (documentació, càmera fixa com a espectador, imatge alterada i la seua postproducció...) utilitzant com a línia argumental la relació entre l'intèrpret i la imatge audiovisual. - Analitzar els límits interns entre les diferents maneres de l'art d'acció i els que aquest manté amb altres disciplines artístiques. Metodologia: Per a aconseguir aquests objectius proposem l'anàlisi d'una sèrie d'accions artístiques amb valor performatiu relacionades amb el mitjà audiovisual en un o un altre dels següents graus: 1. - Documentació: el primer ús que es va fer dels elements audiovisuals va ser el de la documentació, primer mitjançant la càmera fotogràfica i després amb càmeres de cinema i vídeo, que van permetre registrar la dimensió temporal de l'acció. 2. - Interacció: l'acció artística va aconseguir desenvolupar el seu missatge mitjançant l'ús d'elements tecnològics (so, música, autòmats, projeccions de diapositives o filmacions, monitors de TV, etc.) 3. - Creació: la flexibilitat que atorga el mitjà videogràfic i la senzillesa de les seues tècniques, van possibilitar que les tècniques narratives ja avançades pel cinema foren assimilades en una nova pràctica artística, la vídeoperformance. La investigació s'ha estructurada en aquests punts, analitzant distintes obres atenent a la presència d'alguna característica que permeta enquadrar-la en un o un altre. Resultats: D'aquesta anàlisi s'han extret conclusions generals com són els límits variables de la pràctica de la performance, el seu caràcter híbrid en incorporar elements físics i expressius dispars, la necessitat de documentar l'acció i la importància del tractament de l'element temporal i la seua relació amb el temps de representació.

This dissertation consists of three self-contained essays in microeconomics. The first chapter studies a principal-agent model where a biased agent can costly collect information useful for the principal. I study what is the optimal contract the principal should commit to, when she cannot do contingent transfers to the agent. When the agent's value of information is higher than its cost, the optimal mechanism is a threshold delegation rule. The principal allows the agent to choose among all the available actions up to some threshold. This threshold is increasing in the parameter measuring the cost of information. Otherwise, the principal will commit to extreme biased behavior to induce information acquisition. The utility of the principal is non-monotonic in the cost of information. While inducing information acquisition becomes more difficult with higher cost, certain deviations in the acquisition stage become more expensive and thus less profitable for the agent. The second chapter is coauthored with Julie Pinole. Knowing that Individuals interact with their peers, we study how a social planner can intervene, changing these interactions, in order to achieve a particular objective. When the objective is welfare maximization, we describe the interventions for games of strategic complements and strategic substitutes. We show that, for strategic complements, the planner uses resources to target central players; while she divides individuals into separated communities in the case of strategic substitutes. We study which connections she targets in order to achieve these goals. The third chapter is coauthored with Julie Pinole and analyzes a model of contagion on social network. We ask how a social planner should intervene to prevent contagion. We characterize the optimal intervention and the cost associated. We discuss the intuition behind the choice of the planner and we provide comparative static on the cost of intervention for different type of network.

Повний текст джерелаLa idea y el tema de la tesis surgieron de la gran importancia del método control directo del par (DTC), que últimamente se planteó como estrategia alternativa del control vectorial debido a ciertas ventajas frente a este último. Por este motivo, y animados por el éxito logrado por el DTC, se quiere contribuir a un aumento del mismo utilizando varias topologías de inversores que amplíen o extiendan el área de aplicación de los accionamientos basados en el mismo en un rango que vaya desde bajas potencias hasta las potencias medianas.
Aunque los objetivos principales de aplicar el DTC son obtener un accionamiento de comportamiento dinámico alto y buen funcionamiento durante el régimen estático, no obstante los requisitos de funcionamiento en el rango de las bajas potencias no son los mismos que aquellos de potencias medianas. En el rango de las bajas potencias, el coste total del conjunto del accionamiento (inversor - motor - circuitos de control) es un factor muy importante. Especialmente con las normas europeas que obligan a los fabricantes de inversores a mejorar la utilización de la red por ejemplo, limitando la tasa de distorsión armónica, y mejorando el factor de potencia, con lo cual se sustituyen el rectificador pasivo (diodos) por un rectificador activo (transistores), lo que aumenta el coste del accionamiento. Evidentemente, cualquier ahorro en el coste del inversor y los sensores permitirá la aplicación del DTC en gran escala. Por tanto, se ha elegido un inversor de cuatro interruptores (B4) que permite disminuir el coste del inversor y su circuito de control. Reduciendo también el número de sensores utilizados en el sistema. Esta técnica es nueva para este tipo de inversor, ya que el DTC nunca se había realizado basado en este esquema de inversor. Los estudios realizados en esta tesis mediante la simulación y sus validaciones experimentales han probado el buen comportamiento dinámico y estático del accionamiento.
De otro parte, en el rango de potencia mediana (10 kW-100 kW) la aplicación del DTC esta limitada por la frecuencia de conmutación. La exigencia de una frecuencia de conmutación elevada hace aumentar las pérdidas de conmutación a través los interruptores del inversor. Los problemas generados por la conmutación rígida impiden subir la frecuencia de conmutación por encima de unos pocos cientos de hertz. Por ello, si el algoritmo del DTC se aplica teniendo en cuenta la limitación de la frecuencia de conmutación a estos pequeños valores, su comportamiento será bastante malo generando una distorsión en las formas de las ondas del par y del flujo, lo que a su vez se refleja en la velocidad y en las corrientes del motor. Para evitar estos problemas sería más conveniente utilizar un inversor resonante, pero también éste tiene algunos inconvenientes.
En la tesis, se propone utilizar un inversor de tipo cuasi-resonante que tiene las ventajas de inversor resonante y las ventajas del inversor de conmutación dura. En tal caso, se conmutan los interruptores bajo la condición de cero tensión (ZVS) bajando al mínimo las pérdidas de conmutación lo que finalmente permite aumentar la frecuencia de conmutación hasta valores elevados del orden de 10 kHz. Además, la utilización de este tipo de inversor ofrece algunas ventajas como:
- Limitar la dv/dt de la tensión que alimenta el motor, por tanto las corrientes de fugas parásitas se disminuyen, reduciendo la degradación o el envejecimiento de los aislantes de los devanados y de los cojinetes de la máquina, prolongando su vida útil.
- Bajar el nivel de las interferencias electromagnéticas.
- Reducir el tamaño de los radiadores de calor necesarios.
Se ha diseñado y construido un inversor cuasi-resonante con los correspondientes circuitos de control para aplicar el DTC a los accionamientos de baja potencia. Además, se han desarrollado dos circuitos de resonancia. Los resultados obtenidos por simulación y los ensayos experimentales han probado el buen comportamiento de estos circuitos.

Se explica el funcionamiento del inversor cuasi-resonante, mediante un ejemplo de circuito de resonancia. Además se plantea otro circuito que se ha modificado para mejorar la respuesta y el funcionamiento del inversor. También, se presenta el sistema del DTC basado en este tipo de inversor.

O músculo serrátil anterior foi o que evidenciou uma maior atividade muscular, com cerca de 38,41% de contração máxima voluntária, sendo que os valores mais altos foram observados em superfícies estáveis. O músculo que evidenciou menos atividade muscular foi o trapézio superior. Conclusão: A atividade electromiográfica dos músculos em questão variam consoante o tipo de variação dos exercícios efetuados. No entanto o músculo serrátil anterior apresentou os maiores níveis de atividade eletromiográfica em todas as variações dos exercícios propostos.
Objective: The aim of the present study is to analyze the electromyographic activity of the anterior serratus muscle, upper and lower trapezius throughout the box position and plank exercise, with different variations and surfaces. Methodology: The electromyographic activity of announced muscles was realized in fifteen participants (mean age 22.00±2.00 years; BMI 23.41±3.83 kg/m2) in different variations of box position and plank, being placed electrodes according to the preference of the participants. Results: Significant differences were found when the electromyographic activity were analyzed in the various muscles in each variation but also in every muscle between the variations. The anterior serratus muscle was what showed greater muscular activity, with value of 38.41% of maximum voluntary contraction, with the higher values verified on stable surfaces. The muscle that showed less muscular activity was the upper trapezius muscle. Conclusion: The present electromyographic muscular activity changes depending on the type of variation of performed exercises. However, the anterior serratus muscle presented higher levels of electromyographic activity in each exercise variation proposed.

Assim, o facto de após terminar o curso, ter trabalhado em diversas áreas nas três empresas que integrei, desde o desenvolvimento aplicacional em ERP e CRM, na definição de requisitos de arquitecturas de HW e SW, na qualidade e integração de dados em múltiplos sistemas e em modelos analíticos, sempre em metodologias e ambientes diversos. Esta multiplicidade de cenários faz-me pensar que me encontro actualmente na área certa, o Business Intelligence. O curso na FCT-UNL transmitiu-me entre outras, uma capacidade de adaptação ao nível das mais diversas tecnologias e metodologias, assim como uma grande tolerância à frustração, devido aos inúmeros obstáculos que foram sendo colocados durante o curso. Tudo isto tem permitido ao longo da minha carreira ultrapassar as sempre difíceis tarefas a nível técnico, funcional e de gestão que me foram surgindo. Dados, Informação, Conhecimento e Inteligência é um fluxo natural e uma motivação para criar soluções de Business Intelligence. O fluxo descrito deve ser seguido em qualquer SI/TIC. Não é profícuo para nenhuma organização ter dados provenientes de inúmeras aplicações, se estes não gerarem informação que se traduza em conhecimento. O fluxo deve ser cumprido, para que o produto final de um projecto de Business Intelligence seja um acréscimo de conhecimento e valor para a organização ao qual pertence.

Повний текст джерелаAlthough a considerable amount of research into beer consumer behavior has been conducted in several countries, no publicly available such study performed in Portugal has been found. The aim of this research is to understand young consumers' perceptions regarding six brands available in Portuguese retailers and to compare the results with other studies. In this research the author developed a conceptual framework and defined hypotheses, permitting an answer to the purpose of this investigation. Different techniques for collecting data such as surveys and experimentations were used and analysed statistically. The findings suggest that the presence of the brand and packaging are determinant in the formation of consumers' sensorial expectations and play a central role in consumers' evaluation, even if those attributes are not recognized as more important in consumers'perspectives. The majority of participants were unable to Recognize their favourite brand in the blind-test evaluation, and the two brands that were rated in last positions in the survey climbed to the top when they were not identifiable, even if in consumers'perspectives the taste is the most important attribute when choosing a beer. The main beneficiaries of the research should be breweries and, more precisely, marketing and brand managers because it provides important insights into the attributes young consumers value most and suggests strategies for marketing and advertising campaigns. The research can also provide an academic contribution because it specifies the processes to conduct blind test experimentations and suggests further studies based on the investigation results. It also, once again, makes obvious the importance of brand awareness.

Повний текст джерелаCompetition law and its enforcement have become necessary tools in the face of trade liberalisation. Nowhere is this more evident than in the area of cross-border cartels. The global South is steadily becoming aware of this. With the advent of globalisation and trade liberalisation, individual economies have become intrinsically linked. Anti-competitive conduct in one territory may have an impact in another territory. Therefore, an effective regional competition law framework complements trade liberalisation, especially in light of the principal objective of the South-South regional economic communities: the deepening of regional integration, in order to realise economic development and alleviate poverty. Cartel practices, such as, market allocation cartels, are in direct contradiction to this primary objective. This is when enforcement collaborations in South-South regional economic communities becomes crucial. The regional legal instruments of the Common Market for Eastern and Southern Africa, the East African Community, the Southern African Customs Union and the Southern African Development Community make provision for enforcement collaborations among Member States. To facilitate collaboration, regional competition authorities have been created to investigate, among other things, cross-border cartels. Within these economic communities, there is a strong case for enforcement collaborations, as evidence shows that the majority of the firms engaging in cartels are the so-called Regional Multinational Corporations. They operate throughout the territories of Member States. Additionally, the international nature of cartels, such as, private international cartels and export cartels, provide an opportunity for South-South co-operation to be utilised. However, this co-operation has not been utilised to the fullest extent, especially with reference to cross-border cartel activities. This has been attributed to various factors, such as, institutional incapacities, resource austerity, the absence of common procedural rules, the lack of adequate investigatory tools, and political ineptitude. As a solution, this current study makes specific recommendations that are directed at enhancing the effectiveness of South-South collaborations pertaining to cross-border cartel activities.
