Solar energy decision support system

Energy plays a prominent role in human society. As a result of technological and industrial development,the demand for energy is rapidly increasing. Existing power sources that are mainly fossil fuel based are leaving an unacceptable legacy of waste and pollution apart from diminishing stock of fuels.Hence, the focus is now shifted to large-scale propagation of renewable energy. Renewable energy technologies are clean sources of energy that have a much lower environmental impact than conventional energy technologies. Solar energy is one such renewable energy. Most renewable energy comes either directly or indirectly from the sun. Estimation of solar energy potential of a region requires detailed solar radiation climatology, and it is necessary to collect extensive radiation data of high accuracy covering all climatic zones of the region. In this regard, a decision support system (DSS)would help in estimating solar energy potential considering the region’s energy requirement.This article explains the design and implementation of DSS for assessment of solar energy. The DSS with executive information systems and reporting tools helps to tap vast data resources and deliver information. The main hypothesis is that this tool can be used to form a core of practical methodology that will result in more resilient in time and can be used by decision-making bodies to assess various scenarios. It also offers means of entering, accessing, and interpreting the information for the purpose of sound decision making.

Estrategias y fundamentos del discurso alfonsí : una tentativa de romper con el topos literario de la especularidad

Resumen: Incluso antes de su llegada al trono, Alfonso X (1252-1284) emprendió una amplia labor de recopilación, traducción y reescritura de obras, tanto jurídicas, históricas como científicas. Numerosos estudios han subrayado tanto la coherencia de este proyecto como su funcionalidad política, en la medida en que dibuja un nuevo marco de relaciones en el reino y en la corte. En este trabajo, basado en la producción historiográfica y en parte de las obras científicas elaboradas en el scriptorium de Alfonso X, se intentará mostrar que esta producción textual supone una renovación, no sólo en el ámbito político sino también discursivo, y no sólo por la ruptura que supone la utilización del castellano. El análisis de prácticas tales como la compilación, la reescritura y la traducción, que remitirían en principio a una clara continuidad con la tradición textual anterior, permite por el contrario tomar la medida del salto cualitativo que representa la obra alfonsí en cuanto al sentido mismo que se la da a la escritura. La interpretación a la que se pretende llegar es que, si bien los colaboradores regios compilan, reescriben y traducen, la perspectiva desde la que el rey, considerado como autor de las obras, ordena los saberes que estas actividades producen, supone romper con el topos fundador de gran parte de la literatura medieval, la metáfora del espejo, según la cual el libro revela la verdad en la medida en que revela y refleja el mundo, es decir el orden divino

El poder educativo de la televisión : un discurso paralelo a la escuela

[Es] En este trabajo se parte de la hipótesis de que los propios contenidos televisivos son fuente de aprendizaje a través de las narraciones televisivas. En concreto, defendemos la idea de que es posible enseñar y aprender valores a través de dichas narraciones. Se sistematizan algunas de las investigaciones que han abordado la relación entre televisión y valores desde una triple dimensión: los propios contenidos; el medio en sí mismo y el lenguaje. Esta revisión nos permite defender que las condenas reiteradas a la televisión, responsabilizándola de la mayoría de los males que sufre la juventud, no pueden apoyarse en los estudios que la psicología ha realizado en las últimas décadas. Entendemos que el telespectador incorpora la información televisiva desde distintos contextos y que la enculturación no es unidireccional. Existe una interacción entre contextos de desarrollo y mensajes. Concretamente nos interesa analizar los valores implícitos y explícitos que subyacen a los contenidos televisivos. Para ello basándonos en el modelo elaborado por Schwartz y Bilsky hemos creado un cuestionario (Val-TV 01) con el fin de clasificar los valores e interpretar las conductas visualizadas en los textos televisivos y relacionarlos con los propios valores de los adolescentes.

Proceedings of the Eighteenth International Sea Turtle Symposium, 3-7 March 1998, Mazatlán, Sinaloa, Mexico

For the first time in its history, the International Symposium on Sea Turtle Biology and Conservation migrated to a site outside of the United States. Thus the Eighteenth edition was hosted by the Mazatlán Research Unit of the Instituto de Ciencias del Mar y Limnología of the Mexican National Autonomous University (UNAM) in Mazatlán, Sinaloa (Mexico) where it was held from 3-7, March, 1998. Above all, our symposium is prominent for its dynamism and enthusiasm in bringing together specialists from the world´s sea turtle populations. In an effort to extend this philosophy, and fully aware of how fast the interest in sea turtles has grown, the organizers paid special attention to bring together as many people as possible. With the tremendous efforts of the Travel Committee and coupled with a special interest by the Latin American region´s devotees, we managed to get 653 participants from 43 countries. The number of presentations increased significantly too, reaching a total of 265 papers, ranging from cutting-edge scientific reports based on highly sophisticated methods, to the experiences and successes of community-based and environmental education programs. A priority given by this symposium was the support and encouragement for the construction of "bridges" across cultural and discipline barriers. We found success in achieving a multinational dialogue among interest groups- scientists, resource managers, decision makers, ngo's, private industry. There was a broad representation of the broad interests that stretch across these sectors, yet everyone was able to listen and offer their own best contribution towards the central theme of the Symposium: the conservation of sea turtles and the diversity of marine and coastal environments in which they develop through their complicated and protracted life cycle. Our multidisciplinary approach is highly important at the present, finding ourselves at a cross roads of significant initiatives in the international arena of environmental law, where the conservation of sea turtles has a key role to play. Many, many people worked hard over the previous 12 months, to make the symposium a success. Our sincerest thanks to all of them: Program committee: Laura Sarti (chair), Ana Barragán, Rod Mast, Heather Kalb, Jim Spotilla, Richard Reina, Sheryan Epperly, Anna Bass, Steve Morreale, Milani Chaloupka, Robert Van Dam, Lew Ehrhart, J.

Once again, Ed Drane worked his usual magic with the Treasury of the Symposium Significant financial contributions were generously provided by government agencies. SEMARNAP (Mexico´s Ministry of Environment, Natural Resources and Fisheries) through its central office, the Mazatlán Regional Fisheries Research Center (CRIP-Mazatlán) and the National Center for Education and Capacity Building for Sustainable Development (CECADESU) contributed to the logistics and covered the costs of auditoria and audiovisual equipment for the Symposium, teachers and their hotels for the Community Development and Environmental Education workshop in the 5th Latin American Sea Turtle Specialists; DIF (Dept of Family Affairs) provided free accomodation and food for the more than 100 participants in the Latin American Reunion. In this Reunion, the British Council-Mexico sponsored the workshop on the Project Cycle. The National Chamber of the Fisheries Industry (CANAINPES) kindly sponsored the Symposium´s coffee breaks. Personnel from the local Navy (Octave Zona Naval) provided invaluable aid in transport and logistics. The Scientific Coordination Office from UNAM (CICUNAM) and the Latin American Biology Network (RELAB) also provided funding. Our most sincere recognition to all of them. In the name of this Symposium´s compilers, I would like to also express our gratitude to Wayne Witzell, Technical Editor for his guidance and insights and to Jack Frazier for his help in translating and correcting the English of contributions from some non-native English speakers. Many thanks to Angel Fiscal and Tere Martin who helped with the typing in the last, last corrections and editions for these Proceedings. To all, from around the world, who generously helped make the 18th Symposium a huge success, shared their experiences and listened to ours, our deepest gratitude! (PDF contains 316 pages)

Neural routing circuits for forming invariant representations of visual objects

This thesis presents a biologically plausible model of an attentional mechanism for forming position- and scale-invariant representations of objects in the visual world. The model relies on a set of control neurons to dynamically modify the synaptic strengths of intra-cortical connections so that information from a windowed region of primary visual cortex (Vl) is selectively routed to higher cortical areas. Local spatial relationships (i.e., topography) within the attentional window are preserved as information is routed through the cortex, thus enabling attended objects to be represented in higher cortical areas within an object-centered reference frame that is position and scale invariant. The representation in V1 is modeled as a multiscale stack of sample nodes with progressively lower resolution at higher eccentricities. Large changes in the size of the attentional window are accomplished by switching between different levels of the multiscale stack, while positional shifts and small changes in scale are accomplished by translating and rescaling the window within a single level of the stack. The control signals for setting the position and size of the attentional window are hypothesized to originate from neurons in the pulvinar and in the deep layers of visual cortex. The dynamics of these control neurons are governed by simple differential equations that can be realized by neurobiologically plausible circuits. In pre-attentive mode, the control neurons receive their input from a low-level "saliency map" representing potentially interesting regions of a scene. During the pattern recognition phase, control neurons are driven by the interaction between top-down (memory) and bottom-up (retinal input) sources. The model respects key neurophysiological, neuroanatomical, and psychophysical data relating to attention, and it makes a variety of experimentally testable predictions.

The all-seeing mirror: reflecting on vampires as allegories in socio-culturally sensitive literary works

Esta dissertação tem como objetivo analisar a figura do vampiro na literatura como poderosa ferramenta de leitura e interpretação dos medos e angústias que afligem um determinado espaço sociocultural. Ao olhar para a evolução do vampiro literário através dos séculos dezenove, vinte e vinte e um, notamos que cada uma de suas encarnações difere dramaticamente da anterior, e no que o vampiro é reinventado, ele engaja-se num diálogo pertinente e coerente com questões de seu próprio tempo, nunca perdendo assim sua relevância. Sua existência heterogênea, explicitada na dissertação primariamente através das obras Carmilla, de Sheridan LeFanu, Dracula, de Bram Stoker, Eu Sou a Lenda, de Richard Matheson, Entrevista com o Vampiro, de Anne Rice e Fledgling, de Octavia Butler, e as diferentes questões suscitadas em cada uma dessas obras como a sexualidade, a alteridade e o hibridismo nos levarão ao entendimento de que o vampiro pode potencialmente desempenhar importante função alegórica, tornando-se um espelho da própria humanidade através da qual se sustenta

Biographical Sketch of Spencer Fullerton Baird

Spencer Fullerton Baird was born in Reading, Pennsylvania, February 3, 1823. In 1834 he was sent to a Quaker boarding-school kept by Dr. McGraw, at Port Deposit, Maryland, and the year following to the Reading Grammar School. In 1836 he entered Dickinson College, and was graduated at the age of seventeen. After leaving college, his time for several years was devoted to studies in general natural history, to long pedestrian excursions for the purpose of observing animals and plants and collecting specimens, and to the organization of a private cabinet of natural history, which a few years later became the nucleus of the museum of the Smithsonian Institution. During this period he published a number of original papers on natural history. He also read medicine with Dr. Middleton Goldsmith, attending a winter course of lectures at the College of Physicians and Surgeons, in New York, in 1842. His medical course was never formally completed, although in 1848 he received the degree of M. D., honoris causa, from the Philadelphia Medical College. In 1845 he was chosen professor of natural history in Dickinson College, and in 1846 his duties and emoluments were increased by election to the chair of natural history and chemistry in the same institution. In 1848 he declined a call to the professorship of natural science in the University of Vermont. In 1849 he undertook his first extensive literary work, translating and editing the text for the "Iconographic Encyclopedia," an English version of Heck's Bilder Atlas, published in connection with Brockhaus's Conversations Lexikon.

Se você não quer, faça matrícula no pagou-passou da esquina. Concepções de currículo e avaliação: Diálogos sobre um colégio de excelência

O estudo interroga sobres as articulações entre os sentidos de currículo, avaliação e qualidade que circulam entre os professores no contexto do Colégio de Aplicação da Uerj (CAp/UERJ) e que sustentam a legitimidade da instituição considerada de excelência pelos resultados alcançados pelos seus alunos e tem como objetivo identificar as concepções de conhecimento, de currículo e de avaliação que articulam a produção de sentidos de um ensino de qualidade entre os professores do CAp/UERJ? Dessa forma, utilizando aportes pósestruturais a pesquisa é realizada a partir da apropriação dos conceitos de discurso e hegemonia desenvolvido por Ernesto Laclau na Teoria do discurso para problematizar os processos de exclusão que resultam na significação de qualidade sustentada por padrões de desempenho a priori. Para concretizar o estudo, caracterizado como um Estudo de Caso, foram realizadas entrevistas com oito professores abrangendo todos os segmentos de ensino da instituição. Além dos depoimentos, forma consultados documentos institucionais que permitiram contextualizar e compreender melhor o funcionamento do CAp/UERJ. A Análise de Conteúdo foi a ferramenta utilizada na sistematização, leitura e interpretação do material empírico. É importante destacar que não houve na investigação qualquer pretensão de estabelecer juízos de valor sobre as tensões existentes na instituição acerca das concepções que nela circulam e que as falas dos sujeitos são tomadas como interpretações provisórias que cada entrevistado confere as suas experiências no contexto em que a entrevista acontece. Experiências que, por sua vez, também são reinterpretadas pela pesquisadora. Com o estudo foi possível concluir que a significação do CAp/UERJ como uma escola de excelência é um processo dinâmico em que os professores, juntamente com outros sujeitos sociais, nem sempre diretamente ligados à instituição, lutam por hegemonia em práticas coletivas de produção curricular em meio a conflitos que ultrapassam as fronteiras da escola. Essas práticas predominantemente críticas, são centradas na defesa de um repertório de bens simbólicos que podem até ser transmitidos de formas diferentes, com diversas atividades que contemplem a diversidade da escola, mas é na avaliação que elas realmente se concretizam como críticas ao exigir compreensões semelhantes de sujeitos diferentes, principalmente no anos finais de escolaridade. No entanto, ainda que possam ser consideradas hegemônicas e pareçam persistir há algum tempo, como apontam as análises realizadas, trata-se de uma hegemonia precária que se produz em meio a tensões e conflitos nas práticas curriculares da instituição. Assim a proposta da investigação consiste em desestabilizar hegemonias mais estáveis e seus interesses particulares, autorizando que outras hegemonias brotem, promovendo o antagonismo através dos múltiplos discursos.

A biogeographic assessment of the Samoan Archipelago

This report examines the marine biogeography of the Samoan Archipelago (~14º S latitude along the international date-line) with a focus on regional ocean climate, connectivity among islands due to larval transport, distributions of reef fish and coral communities, and the extent of existing marine protected areas. Management decisions and prior assessments in the archipelago have typically been split along the international political boundary between the islands of Samoa and those of American Samoa despite their close proximity and shared resources. A key goal in this assessment was to compile data from both jurisdictions and to conduct the characterization across the entire archipelago. The report builds upon earlier assessments by re-analyzing and interpreting many pre-existing datasets, adding more recent biogeographic data sources, and by combining earlier findings into a multidisciplinary summary of marine biogeography. The assessment is divided into 5 chapters and supporting appendices. Each chapter was written and reviewed in collaboration with subject matter specialists and local experts. In Chapter 1, a short introduction to the overall scope and approach of the report is provided. In Chapter 2, regional ocean climate is characterized using remote sensing datasets and discussed in the context of local observations. In Chapter 3, regional ocean currents and transport of coral and fish larvae are investigated among the islands of the archipelago and surrounding island nations. In Chapter 4, distinct reef fish and coral communities across the archipelago are quantified on the basis of overall biodiversity, abundance, and community structure. In Chapter 5, the existing network of MPAs in American Samoa is evaluated based on the habitats, reef fish, and coral communities that are encompassed. Appendices provide analytical details omitted from some chapters for brevity as well as supplemental datasets needed as inputs for the main chapters in the assessment. Appendices include an inventory of regional seamounts, a description of shore to shelf edge benthic maps produced for Tutuila, analytical details of reef fish and coral datasets, and supplemental information on the many marine protected areas in American Samoa.

Study of ionizable drugs transfer across the water/1,2-dichloroethane interface with phase volume ratio equal to unity using a three-electrode system

The electrochemical behavior of ionizable drugs (Amitriptyline, Diphenhydramine and Trihexyphenedyl) at the water/1,2-dichloroethane interface with the phase volume ratio (r = V-o/V-w) equal to 1 are investigated by cyclic voltammetry. The system is composed of an aqueous droplet supported at an Ag/AgCl disk electrode and it was covered with an organic solution. In this manner, a conventional three-electrode potentiostat can be used to study the ionizable drugs transfer process at a liquid/liquid interface. Physicochemical parameters such as the formal transfer potential, the Gibbs energy of transfer and the standard partition coefficients of the ionized forms of these drugs can be evaluated from cyclic voltammograms obtained. The obtained results have been summarized in ionic partition diagrams, which are a useful tool for predicting and interpreting the transfer mechanisms of ionizable drugs at the liquid/liquid interfaces and biological membranes.

超参数控制下的波阻抗约束反演

The seismic survey is the most effective geophysical method during exploration and development of oil/gas. As a main means in processing and interpreting seismic data, impedance inversion takes up a special position in seismic survey. This is because the impedance parameter is a ligament which connects seismic data with well-logging and geological information, while it is also essential in predicting reservoir properties and sand-body. In fact, the result of traditional impedance inversion is not ideal. This is because the mathematical inverse problem of impedance is poor-pose so that the inverse result has instability and multi-result, so it is necessary to introduce regularization. Most simple regularizations are presented in existent literature, there is a premise that the image(or model) is globally smooth. In fact, as an actual geological model, it not only has made of smooth region but also be separated by the obvious edge, the edge is very important attribute of geological model. It's difficult to preserve these characteristics of the model and to avoid an edge too smooth to clear. Thereby, in this paper, we propose a impedance inverse method controlled by hyperparameters with edge-preserving regularization, the inverse convergence speed and result would be improved. In order to preserve the edge, the potential function of regularization should satisfy nine conditions such as basic assumptions edge preservation and convergence assumptions etc. Eventually, a model with clear background and edge-abnormity can be acquired. The several potential functions and the corresponding weight functions are presented in this paper. The potential functionφLφHL andφGM can meet the need of inverse precision by calculating the models. For the local constant planar and quadric models, we respectively present the neighborhood system of Markov random field corresponding to the regularization term. We linearity nonlinear regularization by using half-quadratic regularization, it not only preserve the edge, and but also simplify the inversion, and can use some linear methods. We introduced two regularization parameters (or hyperparameters) λ2 and δ in the regularization term. λ2 is used to balance the influence between the data term and the transcendental term; δ is a calibrating parameter used to adjust the gradient value at the discontinuous position(or formation interface). Meanwhile, in the inverse procedure, it is important to select the initial value of hyperparameters and to change hyperparameters, these will then have influence on convergence speed and inverse effect. In this paper, we roughly give the initial value of hyperparameters by using a trend- curve of φ-(λ2, δ) and by a method of calculating the upper limit value of hyperparameters. At one time, we change hyperparameters by using a certain coefficient or Maximum Likelihood method, this can be simultaneously fulfilled with the inverse procedure. Actually, we used the Fast Simulated Annealing algorithm in the inverse procedure. This method overcame restrictions from the local extremum without depending on the initial value, and got a global optimal result. Meanwhile, we expound in detail the convergence condition of FSA, the metropolis receiving probability form Metropolis-Hasting, the thermal procession based on the Gibbs sample and other methods integrated with FSA. These content can help us to understand and improve FSA. Through calculating in the theoretic model and applying it to the field data, it is proved that the impedance inverse method in this paper has the advantage of high precision practicability and obvious effect.
