Abstract:
The aim of this paper is to bring out a new perspective for Electricity price forecasting. Numerous studies have focused on forecasting the day-ahead or long-term price forecasting of electricity, rather than examine the relationship between energy commodities, by using various methods. Therefore, this study proposes a model-free approach for electricity price forcasting (EPF). The proposed approach is based on Partial Wavelet Coherency (PWC) and Multiple Wavelet Coherency (MWC) method. These methods are capable of uncovering the coherent time intervals simultaneously for time and frequency domains between the examined time series. VARMA uses the coherent time intervals and outperforms its univariate counterpart (ARMA), both in point and interval forecasting.

Abstract:
This study tried to observe the correlation and coherency between sea surface temperature (SST) and wind velocity in the Malacca Strait at the year of 2015. The SST and wind velocity data with 6 hours interval step have been used in this study. S-Transform, the Cross Wavelet Transform, and the Wavelet Coherency were applied to observe the influence of the variation of sea surface temperature to the wind velocity in Malacca Strait. These methods could produce the phase lag and the time of occurrence between them. S-Transform was used to show the spectrum energy of the sea surface temperature variation. The strongest correlation between them has the period of 32 days during July to August and October to November at each point with significance level of 95 %. The coherency of them has the range of 4 to 64 days at each point. The last result is the spectrum energy of SST variation that has the period of 5 to 50 days at each point. It was similar to the result of the correlation and coherence period between the wind velocity and the SST data

Abstract:
Estimations of the signal component parameters in the case of random equivalent time sampling and under non-coherent sampling condition comprise two main error contributions: spectral leakage effect due to non-coherency and additional noise due to the randomization of sampling intervals. In the estimation procedure the non-parametric interpolated DFT approach has to be used first to estimate the component frequency and, after that, an iterative 4-parametric sine-fit algorithm should be used for other component parameters (amplitude and phase). Their estimations are possible when the duty ratio of random samples from the total samples in the non-coherent measurement interval is above 0.1. With these duty ratios of random samples it is possible to achieve error levels of 0.001 bins of the frequency estimations in relation to the estimation on full ensemble of points.

Abstract:
The lost foam casting (LFC) process utilizes the expanded polystyrene (EPS) foam pattern for the production of metallic components. The thermal degradation of the foam pattern has a significant effect on microstructure of the component. Dendrite coherency is important for the determination of the formation of the solidification structure and cast ability of alloys. The effects of the dendrite coherency on grain size in Mg-4Al alloy have been studied using the two-thermocouple thermal analysis technique in the solidified sample. The results also indicate that the grain size increases with the temperature interval between liquids (TN) and dendrite coherency point (TDCP), The solid fraction at DCP (fsDCP) expressed in percent strongly dependents on the dendrite morphology during solidification.

Abstract:
The main goal of seismic exploration is to get an accurate image of subsurface section so it can be easily interpreted. Pre Stack Depth Migration (PSDM) is such a powerful imaging tool especially for complex area such an area where strong lateral velocity variations exist. The main challenge of PSDM is the need of accurate interval velocity model.In this research, Dix Transformation, coherency inversion, and tomography are used for initial interval velocity model, and then tomography is used for interval velocity model refinement. We compare also between seismic image resulted from PSDM and PSTM to determine the best method. The seismic data that processed in this paper is derived from north western part of Australian Waters.

Abstract:
The spectrum and coherency are useful quantities for characterizing the temporal correlations and functional relations within and between point processes. This article begins with a review of these quantities, their interpretation, and how they may be estimated. A discussion of how to assess the statistical significance of features in these measures is included. In addition, new work is presented that builds on the framework established in the review section. This work investigates how the estimates and their error bars are modified by finite sample sizes. Finite sample corrections are derived based on a doubly stochastic inhomogeneous Poisson process model in which the rate functions are drawn from a low-variance gaussian process. It is found that in contrast to continuous processes, the variance of the estimators cannot be reduced by smoothing beyond a scale set by the number of point events in the interval. Alternatively, the degrees of freedom of the estimators can be thought of as bounded from above by the expected number of point events in the interval. Further new work describing and illustrating a method for detecting the presence of a line in a point process spectrum is also presented, corresponding to the detection of a periodic modulation of the underlying rate. This work demonstrates that a known statistical test, applicable to continuous processes, applies with little modification to point process spectra and is of utility in studying a point process driven by a continuous stimulus. Although the material discussed is of general applicability to point processes, attention will be confined to sequences of neuronal action potentials (spike trains), the motivation for this work.

Abstract:
Transient stability after islanding is of crucial importance because a controlled islanding strategy is not feasible if transient stability cannot be maintained in the islands created. A new indicator of transient stability for controlled islanding strategies, defined as the critical islanding time (CIT), is presented for slow coherency-based controlled islanding strategies to determine whether all the islands created are transiently stable. Then, the stable islanding interval (SII) is also defined to determine the appropriate time frame for stable islanding. Simulations were conducted on the New England test system–New York interconnected system to demonstrate the characteristics of the critical islanding time and stable islanding interval. Simulation results showed that the answer for when to island could be easily reflected by the proposed CIT and SII indicators. These two indicators are beneficial to power dispatchers to keep the power systems transiently stable and prevent widespread blackouts.

Full text
Abstract:
Imaging seismic data requires detailed knowledge of the propagation velocity of compressional waves in the subsurface. In conventional seismic processing, the interval velocity model is usually derived from stacking velocities. Stacking velocities are determined by measuring the coherency of the reflections along hyperbolic moveout trajectories in offset. This conventional method becomes inaccurate in geologically complex areas because the conversion of stacking velocities to interval velocities assumes a horizontally stratified medium and mild lateral variations in velocity. The tomographic velocity estimation proposed in this paper can be applied when there are dipping reflectors and strong lateral variations. The method is based on the measurements of moveouts by beam stacks. A beam stack measures local coherency of reflections along hyperbolic trajectories. Because it is a local operator, the beam stack can provide information on nonhyperbolic moveouts in the data. This information is more reliable than traveltimes of reflections picked directly from the data because many seismic traces are used for computing beam stacks. To estimate interval velocity, I iteratively search for the velocity model that best predicts the events in beam‐stacked data. My estimation method does not require a preliminary picking of the data because it directly maximizes the beam‐stack’s energy at the traveltimes and surface locations predicted by ray tracing. The advantage of this formulation is that detection of the events in the beam‐stacked data can be guided by the imposition of smoothness constraints on the velocity model. The optimization problem of maximizing beam‐stack energy is solved by a gradient algorithm. To compute the derivatives of the objective function with respect to the velocity model, I derive a linear operator that relates perturbations in velocity to the observed changes in the beam‐stack kinematics. The method has been successfully applied to a marine survey for estimating a low‐velocity anomaly. The estimated velocity function correctly predicts the nonhyperbolic moveouts in the data caused by the velocity anomaly.

Abstract:
A mobile user may voluntarily disconnect itself from the web server to save battery life and also to avoid the high communication price. To allow web pages to be updated while the mobile user is disconnected from the web server, updates can be staged in the mobile unit and propagated back to the web server upon reconnection. In this thesis, we investigate methods for supporting disconnected write operations and develop a performance model which helps identify the optimal length of the disconnection period under which the cost of update propagation is minimized. We validate the analytic model with simulation in the thesis. We also show how the result can be applied to real-time web applications with a deadline requirement to propagate updates of web pages. The analysis result is particularly applicable to web applications which allow wireless mobile users to modify web contents while on the go. The algorithms that we have developed can be generally applied to other data items such as files and databases.<br>Master of Science

Abstract:
Este trabalho consiste no desenvolvimento de uma metodologia para a obtenção de representações construtivas de sistemas ordenados de 2ª ordem, baseadas em estruturas de espaços coerentes, com aplicação fundamental na Computação Científica e Matemática Intervalar. Obtêm assim uma representação global para os objetos ditos infinitos relativamente ao conteúdo de informação, como números reais e intervalos reais, de tal forma que possam ser definidos modelos semânticos adequados para os processos computacionais envolvendo tais objetos. Esta representação construtiva é denominada de global, pois é realizada em dois níveis distinguíveis, compreendendo não somente a construção interna dos objetos, no contexto de uma da estrutura de informação, mas também sua estrutura externa de aplicação. A estrutura de informação tem caráter compatível com uma abordagem domínio-teorética, e a estrutura de aplicação e determinada pelo use pretendido do sistema representado. Existe um relacionamento entre os dois níveis de construção, garantindo que cada componente da estrutura de aplicação tenha uma representação interna na estrutura de informação. Os sistemas de representação global resultantes são denominados então espaços coerentes bi-estruturados, e tem a característica adicional de serem gerados por um sistema ordenado basico de universo enumerável. A estrutura de informação é um espaço coerente, com funções lineares e uma estrutura topológica de informação compatível. A estrutura de aplicação - algébrica, de ordem, relacional, funcional, de medidas, topológica, dentre outras - é obtida por um processo construtivo a partir da estrutura do sistema basico. Um espaço coerente bi-estruturado, obtido por esse processo de construção, é a representação global de um dado sistema ordenado de 2ª ordem quando possível recuperar este sistema através do subsistema dos objetos totais do espaço, pela determinação de isomorfismos para a estrutura de aplicação. Da mesma forma, estabelecendo também isomorfismos para o subsistema dos intervalos de elementos do conjunto universo do sistema que esta sendo representado, esse subsistema pode ser recuperado como o subsistema dos objetos quasi-totais do espaço coerente. Apresenta-se também uma abordagem categórica para o processo de construção global, mostrando se que ele determina uma adjunção entre duas subcategorias da categoria SO2 dos sistemas ordenados de 2ª ordem A metodologia proposta se mostrou particularmente interessante na construção do conjunto dos números reais e do conjunto de intervalos reais. Para estes sistemas introduziu-se também uma subestrutura elementar de medidas, pela definição, de forma generalizada, das funções valor absoluto, distância e diâmetro. Foi desenvolvida uma estrutura topológica para os espaços coerentes bi-estruturados, que caracteriza-se também por apresentar dois níveis que se inter-relacionam. Para obter uma caracterização topológica de informação desenvolveu-se a noção de espaços de vizinhanças lineares. No sentido de se obter a caracterização topológica de aplicação, obteve-se, em cada etapa da construção, um espaço de vizinhanças gerado pela função distância generalizada com uma topologia de aplicação associada. Conexões entre as representações de reais e de intervalos de reais e aspectos de computabilidade são referidas de modo preliminar, sugerindo-se este tema como trabalho futuro. Possíveis aplicações dos espaços coerentes bi-estruturados e do processo de construção global a outras áreas da Ciência da Computação são indicadas no final do trabalho.<br>The aim of this work is to develop a methodology to obtain constructive representations of second order ordered systems, based on coherence space structures, with the main application in Scientific Computation and Interval Mathematics. A global representation for the so-called infinite objects considering the information content they represent, in particularly real numbers and real intervals, is obtained, so that suitable semantical models for real and interval computational processes can be provided. This constructive representation is said to be global. since it is performed in two distinguished levels, dealing with the internal construction of the objects, in the context of an information structure, and, on the other hand, building an external application structure. The information structure is compatible with a domain-theoretic approach, and the application structure is established according the intended usage of the represented system. There exists a relationship between the two levels of the construction, guaranteeing that each component of the application structure should have an internal representation in the information structure. The resulting global representation systems are called bi-structured coherence spaces, and they have the additional feature of being generated by a basic ordered system having a denumerable universe. The information structure is a coherence space endowed with linear functions and a compatible information topological structure. The (algebraic, ordered, relational, functional, measure, topological, etc.) application structure is obtained by the construction process, considering the structure of the basic system as the start point. A bi-structured coherence space, obtained by this construction process, is said to be the global representation of a given second order ordered system if it is possible to recover the latter by the subsystem of the total objects of the former, defining isomorphisms related to the application structure. Following the same pattern, establishing isomorphisms for the subsystem of the intervals of elements of the represented system, it is possible to recover it as the subsystem of quasi-total objects of the bi-structured coherence space. A categorical approach is also presented and it is shown that the global construction process determines an adjunction between two subcategories of the category SO2 of the second order ordered systems. The proposed methodology was shown to be particularly interesting when constructing the sets of real numbers and real intervals. For these systems, an elementary measure structure was introduced in a generalised approach, defining generalised distance, diameter and absolute value functions. The bi-structured coherence spaces were given an interrelated two-level topological characterisation. In order to obtain an information topological characterisation the concept of linear neighbourhood systems was introduced. For the application topological characterisation, at each step of the construction, a neighbourhood system generated by the generalised distance function, with an associated topology, was defined. A brief analysis concerning the connections among other representations of real and real intervals and computability aspects is presented. Other possible applications in Computer Science are indicated.

Abstract:
In shallow water environments, sound propagation experiences multiple interactions with the surface/bottom interfaces, with hydrodynamic disturbances such as internal waves, and with tides and fronts. It is thus very difficult to make satisfactory predictions of sound propagation in shallow water. Given that many of the ocean characteristics can be modeled as stochastic processes, the statistical measure, spatial coherence, is consequently an important quantity. Spatial coherence provides valuable information for array performance predictions. However, for the case of long-range, low frequency propagation, studies of spatial coherence influenced by various environmental parameters are limited insofar as having the appropriate environmental data with which to model and interpret the results. The comprehensive Asian Seas International Experiment 2001 (ASIAEX01) examined acoustic propagation and scattering in shallow water. Environmental oceanographic data were taken simultaneously with the acoustic data. ASIAEX01 provided a unique data set which enabled separate study of the characteristics of the oceanographic features and their influence on long range sound propagation. In this thesis, the environmental descriptors considered include sediment sound speed and attenuation, background internal waves, episodic non-linear internal waves, and air-sea interface conditions. Using this environmental data, the acoustic data are analyzed to show the characteristics of spatial coherence in a shallow water waveguide. It is shown that spatial coherence can be used as an inversion parameter to extract geoacoustic information for the seabed. Environmental phenomena including internal waves and wind-generated surface waves are also studied. The spatial and temporal variations in the sound field induced by them are presented. In addition, a tank experiment is presented which simulates propagation in a shallow water waveguide over a short range. Based on the data model comparison results, the model proposed here is effective in addressing the major environmental effects on sound propagation in shallow water.

Ce travail de thèse est consacré à l'exploration de méthodes cohérentes pour la manipulation des états internes d'une nuage atomique. L'objectif final est de créer un schéma pour la réalisation d'une mémoire quantique capable de stocker l'état quantique d'une impulsion lumineuse dans une cohérence atomique. J'ai exploré deux différentes réalisations expérimentales, les deux basées sur la transparence induite électromagnétiquement dans un système à trois niveaux en configuration Lambda. La première réalisation est basée sur sous-niveaux Zeeman d'atomes de césium à température ambiante (réalisé dans le groupe de E. Giacobino au LKB, Paris) en s'appuyant sur la ligne D2. En présence d’élargissement Doppler l'effet EIT est fortement réduite en raison de la présence de transitions adjacentes. Nous avons développé un modèle théorique pour décrire la réponse optique du système, comprenant les contributions des transitions hors résonance.

The final aim is to create a robust scheme for the realization of a quantum memory capable of storing the quantum state of a light pulse in an atomic coherence. I have explored two different experimental realizations, both based on electromagnetically induced transparency in a three level Lambda scheme. The first realization was based on Zeeman sub-levels of Cesium atoms in a room temperature cell (realized in the group of Elisabeth Giacobino at LKB, Paris). In this experiment we characterized a memory based on the D2 line of 133Cs. In the presence of Doppler broadening the EIT effect is strongly reduced due to the presence of adjacent transitions. We developed a model to describe the optical response of the complete system including off-resonant transitions. We then experimentally verified the model and found a method to enhance the transparency based on velocity selective optical pumping. The second realization was instead based on hyperfine states of ultracold Rubidium atoms held in a magnetic microtrap (realized in the group of F. S. Cataliotti at LENS, Firenze). In this experiment we observed a strong reduction (by almost 6 orders of magnitude) in the speed of light within the atomic sample, a promising step towards the realization of coherent information storage. We developed also a method to measure the relative phase of light pulses using atomic interferometry. These findings open an interesting alternative route for the detection of quantum coherence and non-classical states

Abstract:
Neste trabalho desenvolve-se um estudo sobre os Espaços Coerentes Gerados por Conjuntos Básicos, dotados de uma estrutura adicional. Por estrutura adicional entende-se uma estrutura algébrica, de ordem pontual, de medidas, topológica e lógica. Estes espaços, denotados por , constituem uma subcategoria dos Espaços Coerentes, cujos objetos, ordenados pela inclusão, são conjuntos coerentes constituídos por subconjuntos do conjunto básico, os quais estão relacionados pela relação de coerência induzida, que estrutura a teia deste espaço. Os morfismos desta categoria são as funções de objetos geradas por funções básicas. As propriedades algébricas e relacionais destas funções básicas, externas ao processo de construção, ao se propagarem, passam a influenciar na verificação das propriedades internas das funções de objetos. Contudo, este trabalho não é um estudo categórico. A metodologia adotada utiliza a linguagem simples e intuitiva da Teoria dos Conjuntos, que possibilita a visualização e a análise dos relacionamentos existentes, não apenas entre os morfismos que envolvem os objetos totais ou parciais desta categoria, mas também das estruturas ou pré-estruturas externas que os formam, representados pelas funções de tokens e funções básicas. Mostra-se que as funções de objetos são totais e bem definidas, alem de serem monótonas e continuas neste espaço. Entretanto a análise da estabilidade, e consequentemente da linearidade esta associada a injetividade das funções básicas. Uma das características mais importantes da construção proposta e o desenvolvimento de um sistema de representação linear para funções localmente lineares, com a definição do espaço coerente A* gerado pelo produto de subteias. Neste espaço, as funções de objetos são lineares e coincidem com os morfismo da categoria dos espaços coerentes. Além disso, mostra-se que A* e isomorfo ao espaço coerente gerado pelo produto direto dos sub-espaços, ПĄ. Desta forma, toda transformação definida para um tipo de dado estruturado a partir de um conjunto básico enumerável tem uma representação linear, constituída pelos morfismos da categoria dos espaços coerentes. A existência da representação linear para as funções elementares garante a existência da representação linear para outras funções derivadas destas. Apresenta-se ainda uma especificação desta construção, introduzindo-se o Espaço Coerente de Intervalos Racionais, IIQ. Na busca de uma aplicação compatível com uma abordagem computacional, em especial para Análise Real, mostra-se que, em IIQ, cada função real elementar esta identificada com uma função de objetos linear, definida a partir da correspondente função elementar racional. Dentre as funções que foram analisadas destacam-se: a exponencial, a logarítmica, a potência, a potência estendida, a raiz n-ésima, as funções trigonométricas como seno, cosseno e tangente e suas correspondentes funções inversas, como também a função polinomial. Verificou-se que todas estas funções de objetos são totais, bem definidas, ou pertencem ou possuem uma representação linear na categoria COSP-LIN dos espaços coerentes, alem de serem fechadas para os objetos totais e quasi-totais deste espaço, sendo possível estabelecer o correspondente par-projeção para cada uma delas.<br>In this work the Coherence Spaces Generated by Basic Sets with additional structure are studied. By additional structure one means an algebraic, topological and logical structure with a punctual order and a measure system. These spaces, indicated by A, are a subcategory of the category of Coherence Spaces, whose objects, ordered by inclusion, are coherent sets formed by the induced web coherence relation. The morphisms of this category are the functions of objects generated by basic functions. The algebraic and relational properties of these basic functions - external to the construction process - are propagated and cause important influences in the verification of the internal properties of the functions of objects However, this research is not a categorical study. The methodology uses the simple and intuitive language of the Set Theory, which allows the visualization and the analysis of the existing relationships, not only among, the morphisms of the total and partial objects of this category, but also among their structures or pre-structures, represented by the functions of tokens and basic functions. It is shown that the functions of objects are total and well defined. They are also monotone and continuous. However the stability and the linearity of the functions of objects depend on the fact if the basic functions are injective or not. One of the most important features of this construction is the development of a linear representation system for the local linear functions, by the definition of a coherence space A*, which is generated by the subweb product. In this space the functions of objects are linear and therefore they are the morphisms of the category of Coherence Spaces. Moreover, it is proved that A* is isomorphic to the coherence space generated by the directed product of the subspaces, denoted by ПĄ . Then, for each transformation defined for a structured data type considering a denumerable basic set there exists its related linear representation. The existence of a linear representation for elementary functions guarantees the existence of a linear representation for others derived functions. As an application of this construction, the Coherence Space of Rational Intervals, denoted by IIQ, is introduced. In order to show an application which is compatible to a computational approach, specially for the real analysis, each elementary real function is identified with a linear function of objects, defined considering the related elementary rational function. Some of the analyzed functions are the exponential, the logarithmic, the power , the extended power, the root, the trigonometric (sine, cosine and tangent and their relates inverses), and the polynomial functions. It is proved that all of these functions of objects are total and well defined. Moreover, either they belong to the category COPS-LIN of the coherence spaces or they have a linear representation in the same category. It is also possible to define a related projection pair for each one of them.

Abstract:
Objetivo: Estudar e comparar a acuidade visual, metamorfopsia, espessura foveal, camada limitante externa e zona elipsoide por meio da Tomografia de Coerência Óptica (OCT), e a taxa de recorrência dos pacientes operados de remoção de membrana epirretiniana, com e sem a retirada da membrana limitante interna. Métodos: Pacientes com MER operados por um único cirurgião e randomizados, aleatoriamente, em dois grupos. Todos os pacientes tiveram a retirada da membrana epirretiniana: 35 pacientes do Grupo 01, sem a adicional retirada de membrana limitante interna, e 28 pacientes do Grupo 02, com a retirada dessa membrana. Os pacientes foram seguidos e avaliados no primeiro, terceiro e sexto mês. Resultados: Setenta pacientes operados no total, sendo sete excluídos por perda de seguimento. Os pacientes de ambos os grupos evoluíram com melhora gradativa da visão ao longo do tempo. No Grupo 01, a média de acuidade visual inicial foi 0,60 logMAR (±0,3 desvio padrão - DP), no primeiro mês foi 0,49 logMAR (±0,26 DP), no terceiro mês, 0,39 logMAR (±0,30 DP) e no sexto mês, 0,27 logMAR (±0,25 DP). No Grupo 02, a média de acuidade visual inicial foi 0,63 logMAR (±0,25 DP), no primeiro mês foi 0,44 logMAR (±0,26 DP), no terceiro mês, 0,41 logMAR (±0,35 DP), e no sexto mês, 0,43 logMAR (0,44 DP). Não houve diferença estatisticamente significante quanto à melhora da acuidade visual entre os dois grupos. Não foi encontrada diferença estatisticamente significante em relação às alterações na OCT entre os grupos. O Grupo 02 apresentou maior taxa de recidiva (17%) quando comparada com o Grupo 01 (3,6%), embora esta diferença não foi estatisticamente significante (p=0,09). Conclusão: Ambos os grupos apresentaram melhora funcional e anatômica semelhantes, mas o grupo no qual não se removeu a membrana limitante interna mostrou uma possível tendência à maior taxa de recidiva<br>Objective: To study and compare the visual acuity, metamorphosis, foveal thickness, the outer limiting layer and the ellipsoid zone, studied by Optic Coherence Tomography (OCT), and the recurrence rate of patients undergoing removal of epiretinal membrane with and without the removal of the internal limiting membrane. Methods: Seventy patients undergoing removal of epiretinal membrane, by a single surgeon and randomly assigned into two groups. Group 1, without additional removal of internal limiting membrane, 35 patients, and group 2 with the removal of the internal limiting membrane, 28 patients. Both groups were followed and evaluated in the first, third and sixth month. Results: Patients of both groups developed with a gradual improvement of vision over time. In group 1, the mean initial visual acuity was 0.60 logMAR (±0.3 standard deviation - SD), the average visual acuity of the first month was 0.49 logMAR (±0.26 SD), in the third month 0.39 logMAR (±0.30 DP), and in the sixth month logMAR 0.27 (±0.25 SD). In group 2, the mean initial visual acuity was 0.63 logMAR (±0.25 SD), average visual acuity of the first month was 0.44 (±0.26 DP) logMAR, in the third month 0.41 logMAR (±0.35 DP), and in the sixth month 0.43 logMAR (±0.44 DP). There was no statistical difference in improvement in visual acuity between the two groups, there was no statistically significant differences related to tomographic alterations between the groups, but the group 2 showed a higher relapse rate (17%) compared to the group 1 (3.6%). Although the difference is not statistically significant (p=0.09). Conclusion: Both groups showed similar functional and anatomical improvement, but the group which the internal limiting membrane was not removed showed a higher recurrence rate

Abstract:
Objetivos: Comparar as alterações de espessura das camadas da retina macular adquiridas com tomografia de coerência óptica (TCO) e as amplitudes das ondas de eletrorretinograma multifocal (ERGmf) convencional e com estímulo lentificado entre olhos com hemianopsia temporal sequelar por compressão quiasmática e controles saudáveis, além de avaliar as correlações entre TCO, ERGmf e campo visual (CV) central. Métodos: Quarenta e três olhos (30 pacientes) com hemianopsia temporal sequelar por tumores hipofisários previamente submetidos a descompressão quiasmática e 37 olhos saudáveis (19 controles) foram submetidos a TCO-DS da mácula, ERGmf e CV tipo 10-2. Após segmentação, foram medidas as espessuras maculares da camada de fibras nervosas da retina (CFNR), camada de células ganglionares (CCG), camada plexiforme interna (CPI), camada nuclear interna (CNI), camada plexiforme externa (CPE), camada nuclear externa (CNE) e camada de fotorreceptores (CFR). Amplitudes e potenciais oscilatórios (PO) multifocais foram adquiridos com o ERGmf convencional e com estímulo lentificado, respectivamente, analisados em valores médios por quadrantes e hemicampos. Resultados: Espessuras da CFNR, CCG e CPI foram significantemente menores em todos os quadrantes, enquanto CNI, CPE e CFR tiveram medidas significantemente maiores nos quadrantes nasais nos pacientes comparados com os controles. Correlações significantes entre a TCO e os valores de CV 10-2 foram positivas para CFNR, CCG e CPI, e negativas para CNI, CPE e CFR. As amplitudes médias dos POs e de N1 do ERGmf se mostraram significantemente reduzidas na hemirretina nasal dos pacientes. Correlações significantes foram encontradas entre as amplitudes de PO e ERGmf para com medidas de TCO da hemirretina nasal interna e externa, respectivamente. Conclusões: Pacientes com hemianopsia temporal sequelar por compressão quiasmática previamente tratada apresentam adelgaçamento significante de CFNR, CCG e CPI e espessamento de CNI, CPE e CFR, associados com amplitudes reduzidas de PO e N1, sugerindo que o dano axonal à retina interna desencadeia lesão secundária das camadas externas da retina nesta condição<br>Purpose: To compare optical coherence tomography (OCT)-measured macular retinal layers in eyes with permanent temporal hemianopia from chiasmal compression and controls, compare regular and slow-flash multifocal electroretinography (mfERG) in patients and controls, and assess the correlation between OCT, mfERG and central visual field (VF) data. Methods: Forty-three eyes (30 patients) with permanent temporal hemianopia from pituitary tumors previously submitted to chiasm decompression and 37 healthy eyes (19 controls) were submitted to macular SD-OCT, mfERG and 10-2 VF testing. After segmentation, macular retinal nerve fiber layer (RNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), inner nuclear layer (INL), outer plexiform layer (OPL), outer nuclear layer (ONL) and photoreceptor layer plus (PRL+) thickness was measured. Amplitudes and oscillatory potentials (OP) were measured on regular and slow-flash mfERG, respectively, and expressed as mean values per quadrant and hemifield. Results: RNFL, GCL and IPL thickness measurements were significantly reduced in all quadrants while INL, OPL and PRL were significantly increased in the nasal quadrants in patients compared to controls. Significant correlations between OCT and 10-2 SAP measurements were positive for RNFL, GCL and IPL and negative for INL, OPL and PRL. OPs and mfERG N1 amplitudes were significantly reduced in the nasal hemiretina of patients. Significant correlations were found between OP and mfERG amplitudes for inner and outer nasal hemiretina OCT measurements, respectively. Conclusions: Patients with permanent temporal hemianopia from previously treated chiasmal compression displayed significant RNFL, GCL, IPL thinning and INL, OPL and PRL thickening associated with reduced OP and mfERG N1 amplitudes, suggesting axonal injury to the inner retina leads to secondary damage to the outer retina in this condition

L'évolution des précipitations homogènes et hétérogènes a pu être suivie et la composition des précipités a été dans une large mesure identifiée. Au cours de ce travail, les analyses EDX ont montré l'existence de pics qui se sont révélés dus au Coherent Bremsstrahlung. L'importance de ce phénomène, qui peut fausser les analyses nous a conduit à l'étudier séparément dans les alliages précédents, et aussi dans les martensites du même système, montrant que, contrairement à l'opinion généralement admise, ce phénomène peut intervenir dans des alliages de cristallographie complexe et présentant de nombreux défauts

Full text
Abstract:
The ‘Third Man’ in the Parmenides is often reconstructed in terms of unstated background commitments of the Theory of Forms; thus it seems to threaten the internal coherence of that theory. However, the regress can be derived solely from premises explicitly stated within the dialogue, and blocked simply by giving up one candidate account of participation, leaving the central commitments of the Theory of Forms intact. Consequently, the problem highlighted by the argument is not an infinite regress of Forms, but merely the lack of an adequate account of participation. This reading facilitates a coherent account of the dialogue as a whole, using the ‘scorecard’ approach outlined by Zeno himself, and developed more recently for contemporary metaphysics by Lewis and Armstrong: Part I acknowledges non-fatal difficulties for the Forms which are then eclipsed by more serious issues for Eleatic monism in Part II.

Full text
Abstract:
Internalism implies that rationality requires nothing more than what in the broadest sense counts as ‘coherence’. The earlier chapters of this book argue that rationality is in a strong sense normative. But why does coherence matter? The interpretation of this question is clarified. An answer to the question would involve a general characterization of rationality that makes it intuitively less puzzling why rationality is in this strong sense normative. Various approaches to this question are explored: a deflationary approach, the appeal to ‘Dutch book’ theorems, the idea that rationality is constitutive of the nature of mental states. It is argued that none of these approaches solves the problem. An adequate solution will have to appeal to some value that depends partly on how things are in the external world—in effect, an external goal—and some normatively significant connection between internal rationality and this external goal.

Full text
Abstract:
A familiar story about reference that developed in the 1970s appeared to offer a light at the end of the tunnel of positivist theories of meaning. Coherence theories of truth and justification, paradigm shifts, and incommensurability stalked the land. Causal theories of reference (Kripke 1980) promised to change all that and restore scientific realism. But another dialectic took hold that led to what Putnam called internal realism. This chapter aims to rescue Putnam from internal realism, and to breathe new life into real realism. It also aims to rescue science from Plantinga’s argument N (and arguments O and K). That will allow an answer to perhaps the strongest link in the chain of arguments that Naturalism is epistemically self-defeating. The chapter offers a diagnosis of the central difficulty that appears to wreak havoc with the realist aspirations of causal theories of reference. Finally, a cure is offered for that malady.

Abstract:
This chapter examines the differences within liberationists’ ranks, and how counter-challenges from a consensus theology in its last throes tested the coherency of liberation theology. As the new Latin American theology challenged the U.S. empire, black and feminist theologians within its borders found an institutional space in which to incubate a new orthodoxy and engage in internal debate. Latin America, historically an object of North American missionary and political expansion, drew the bulk of the relevant attention, casting the entire enterprise of liberation theology as a Latin American product and a problem for U.S. regional political and cultural dominance. The fragmented liberal theological establishment of the United States and the weakened Catholic cultural hegemony in Latin America shaped the reception of liberation theology, allowing the establishment of a new orthodoxy.

The chapters in this volume are uniform in their commitment to the proposition that terrorism can be effectively fought and national security interests can be defended within a system of oversight and control that protects both corporate interests and individual privacy. Moreover, they are remarkable in their consistency in describing the components of an effective system of checks and balances. This chapter draws on the work of the contributors to this volume and on the flood of policy developments over the past five years to recommend a coherent framework for collection of private-sector data. The elements of this framework for governments are legality, proportionality, and accountability. For corporations, they are based on adoption of internal policies, internal and external accountability, and transparency, backed up by a willingness to challenge overbroad or unjustified government demands.

Abstract:
Orwell’s writings repeatedly extol the virtues of solidarity, or what he liked to call brotherhood. But brotherhood was often something of an ordeal for Orwell as much as it was a coveted value and practice. The issue may be partly a question of character, but it also had a conceptual element: a) the compatibility of solidarity with other values, b) its internal coherence, as it sometimes re-enlists the social divisions it seeks to transcend, c) its problematic scope given its seemingly partisan nature, and d) its practicality in a modern social setting. This chapter examines these four issues in detail, showing how they contribute to the particular heft of Orwell’s writing—its angular sympathies and superbly uneven tone.

Full text
Abstract:
Abstract X-ray propagation-based phase-enhanced imaging is a powerful new technique that uses the x-ray beam coherence to greatly improve the image contrast. With the high x-ray beam brilliance (or alternately, good beam coherence) available at third-generation synchrotron sources, such as the Advanced Photon Source (APS), propagation-based phase-enhanced imaging can be easily accomplished. The power of this technique lies in its simplicity — it is an in-line geometry and requires little or no beam manipulation, and it works over the entire range of accessible energies (10–100 keV). Unlike conventional radiography, its contrast mechanism is mostly due to Fresnel diffraction and not absorption. The technique works for soft biological samples, as well as thick (several millimeters) stainless-steel samples. In this paper, we demonstrate the utility of this technique to study several fuel injectors and compare the results with conventional absorption radiography. The possibility of extending this technique to time-resolved imaging studies on the fuel injector will be discussed.

Abstract:
There is increasing interest in the question of how different stakeholders develop, implement and lead regional upgrading processes with the concept of place leadership emerging as one response to this. Simultaneously, universities face growing expectations that they will contribute to regional development processes – often through their collaborative relationships with other regional stakeholders. But universities are complex in terms of their internal and institutional structures, which undermines their capacities to enact coherent place leadership roles. We seek to understand how strategic leadership in universities can contribute to innovation and regional development in the context of the fundamental institutional complexity of universities. We address this through a qualitative, explorative case study comparing six European regions where universities have sincerely attempted to deliver place leadership roles. We identify that the elements of agency and alignment are vital in that: firstly, university leadership has to align with regional coalitions on the one hand and internal structures on the other hand, and secondly, this leadership must give individuals agency in their regional engagement activities.
