Grades Computacionais (grid computing) já é uma realidade tanto no meio acadêmico quanto no meio empresarial. Seu uso se tornou popular principalmente devido à divulgação dos trabalhos nesta área e pela propaganda de produtos e softwares que oferecem essa idéia. Apesar disso, ambientes para o desenvolvimento de aplicações orientadas a objetos em Java para uma infra-estrutura de grid ainda é escasso. Algumas iniciativas oferecem bibliotecas para este desenvolvimento. Outras utilizam paradigmas diferentes, como o de passagem de mensagem, para o desenvolvimento de aplicações. Além disso, a própria infra-estrutura de grid, formada por diferentes domínios administrativos com diferentes políticas de segurança e uso, impede que as aplicações sejam executadas nos diversos níveis existentes no grid. Estes níveis, formados por computadores e clusters de computadores com nós de execução, possuem endereçamento privado, impossibilitando que as aplicações alocadas em cada um desses computadores/nós, em diferentes domínios e diferentes endereços, se comuniquem de forma transparente. Visando uma solução para esses problemas, esta tese apresenta um ambiente para programação orientada a objetos distribuídos e paralelos...

Este trabalho tem por objetivo avaliar a perspectiva econômica e modelo de negócio da tecnologia de telecomunicação nas redes de distribuição de energia elétrica. Essa integração entre a tecnologia de telecomunicação e a rede de distribuição constitui um sistema conhecido como rede inteligente ou smart grid. Neste estudo são analisados os modelos de rede inteligentes mais significativos do mundo, os quais ainda se encontram em fase inicial. Na análise da implantação da rede inteligente em diversos países, observa-se a existência de diferentes motivações. Por exemplo, no caso norte-americano, trata-se dos esforços do setor de energia em garantir a confiabilidade no abastecimento. Na Europa, há um grande comprometimento com a redução de carbono e gases causadores do efeito estufa. No Brasil, busca-se uma estratégia para melhorar aspectos técnicos da distribuição, diminuir as perdas técnicas, eliminar ou reduzir o roubo de energia e ajustar a oferta de energia com o crescimento urbano e industrial, aprimorando a regulamentação sobre o setor. Além da ausência de padrões de telecomunicação, que se constitui em restrição para todos os projetos de smart grid, o Brasil apresenta grandes entraves para a implantação da rede inteligente...

Dissertação (mestrado)—Universidade de Brasília, Instituto de Ciências Exatas, Departamento de Ciência da Computação, 2007.; Um sistema distribuído consiste em um conjunto de elementos computacionais que se comunicam através de uma rede de interconexão e que utilizam um software que permite que trabalhem de maneira cooperativa e coordenada. Visando o compartilhamento de recursos em larga escala, foi proposta a Computação em Grid, um tipo de sistema distribuído cujo objetivo é o compartilhamento de recursos geograficamente distribuídos, autônomos e pertencentes a diferentes domínios administrativos. Algumas aplicações executadas em grid podem necessitar de garantias de disponibilidade de recursos. Para que tais aplicações sejam satisfeitas, faz-se necessário o fornecimento de garantias de Qualidade de Serviço (QoS). QoS consiste em um conjunto de características quantitativas e qualitativas de um sistema necessárias para que seja alcançado o nível de serviço esperado pelas aplicações. Um meio de se fazer a negociação dos níveis de QoS fornecidos às aplicações é a utilização de acordos de serviço, pelos quais a parte fornecedora se compromete a prover o nível de serviço desejado. A presente dissertação propõe o GrAMoS (Grid Agreement Monitoring Service)...

We introduce a grid cell microcircuit hypothesis. We propose the ‘grid in the world’ (evident in grid cell discharges) is generated by a ‘grid in the cortex’. This cortical grid is formed by patches of calbindin-positive pyramidal neurons in layer 2 of medial entorhinal cortex (MEC). Our isomorphic mapping hypothesis assumes three types of isomorphism: (i) metric correspondence of neural space (the two-dimensional cortical sheet) and the external two-dimensional space within patches; (ii) isomorphism between cellular connectivity matrix and firing field; (iii) isomorphism between single cell and population activity. Each patch is a grid cell lattice arranged in a two-dimensional map of space with a neural : external scale of approximately 1 : 2000 in the dorsal part of rat MEC. The lattice behaves like an excitable medium with neighbouring grid cells exciting each other. Spatial scale is implemented as an intrinsic scaling factor for neural propagation speed. This factor varies along the dorsoventral cortical axis. A connectivity scheme of the grid system is described. Head direction input specifies the direction of activity propagation. We extend the theory to neurons between grid patches and predict a rare discharge pattern (inverted grid cells) and the relative location and proportion of grid cells and spatial band cells.

We examined the accuracy with which the location of an agent moving within an environment could be decoded from the simulated firing of systems of grid cells. Grid cells were modelled with Poisson spiking dynamics and organized into multiple ‘modules’ of cells, with firing patterns of similar spatial scale within modules and a wide range of spatial scales across modules. The number of grid cells per module, the spatial scaling factor between modules and the size of the environment were varied. Errors in decoded location can take two forms: small errors of precision and larger errors resulting from ambiguity in decoding periodic firing patterns. With enough cells per module (e.g. eight modules of 100 cells each) grid systems are highly robust to ambiguity errors, even over ranges much larger than the largest grid scale (e.g. over a 500 m range when the maximum grid scale is 264 cm). Results did not depend strongly on the precise organization of scales across modules (geometric, co-prime or random). However, independent spatial noise across modules, which would occur if modules receive independent spatial inputs and might increase with spatial uncertainty, dramatically degrades the performance of the grid system. This effect of spatial uncertainty can be mitigated by uniform expansion of grid scales. Thus...

e-Science is a terminology denoting modern scientific experiments and studies being carried out with the support of large-scale Grid infrastructures. The essence of a Grid is to enable resource sharing, including compute resources and storage resources, to as many authorised people as possible. This thesis has made several contributions towards building a national grid infrastructure, by designing and implementing new approaches to simplify the use of the Grid so as to enlarge the user base of grid infrastructure and e-Science. These new systems have been deployed as part of the Australian national grid infrastructure, however the approaches used aim to provide a generic solution so that other grid operators and users can also benefit from it. Our exploration of existing data grid systems has shown that these are not easy for researchers to use, since they require users to have certain IT knowledge, and rarely have a user-friendly interface. My approach is to develop a web portal based upon a widely-used data grid system, iRODS, that is able to make use of geographically distributed storage resources. This new interface not only supports the WebDAV standard, enabling easy drag-and-drop file access, but also provides a web interface...

The objective of the study was to develop an adequate policy and governance framework for off- grid rural electrification by: assessing the effectiveness and key socio-economic factors and governance structures in present off-grid electricity supply schemes; and exploring and testing sustainable decentralized service-delivery models for future large-scale off-grid rural electrification in Pakistan. This study has attempted to develop a policy and governance framework for implementing sustainable large-scale off-grid rural electrification in Pakistan. This was done by assessing the effectiveness of existing policy, governance, and institutional frameworks in actual implementation of off-grid supply (OS) projects in the country; examining regional and global models for off-grid supply which have worked; and exploring which combination of these experiences might work to scale-up access in Pakistan to reach the roughly 7,000 villages which are not likely to be supplied by grid electricity in the near future. Pakistan has in place...

This report provides some practical guidance on how utilities can define their own smart grid vision, identify priorities, and structure investment plans. While most of these strategic aspects apply to any area of the electricity grid, the document focuses on the segment of distribution. The guidance includes key building blocks that are needed to modernize the distribution grid and provides examples of grid modernization projects. Potential benefits that can be achieved (in monetary terms) for a given investment range are also discussed. The concept of the smart grid is relevant to any grid regardless of its stage of development. What varies are the magnitude and type of the incremental steps toward modernization that will be required to achieve a specific smart grid vision. Importantly, a utility that is at a relatively low level of grid modernization may leap frog one or more levels of modernization to achieve some of the benefits offered by the highest levels of grid modernization. Smart grids impact electric distribution systems significantly and sometimes more than any other part of the electric power grid. In developing countries...

There is an international effort to develop smart grids to overcome the problems caused by aging power grids. However, to immigrate to the new grid, the IT infrastructure has to be integrated with the current power grid. There is currently an ongoing debate surrounding what would be the best choice for smart grid communication technology. One of the promising communication technologies for smart grid realization is powerline communication (PLC). PLC provides utilities the opportunity of managing their own network infrastructure. Power cables are everywhere; even rural areas are covered with power cables. However, because of its noisy environment and the low capacity of narrowband powerline communication (NBPLC), its viability for smart grid realization is being questioned. To investigate this issue, smart grid communication network requirements and powerline communication technologies and channel models are studied. Then, using MATLAB and Network Simulator-2, powerline communication and a smart grid communication network (SGCN) are simulated. The performance of different powerline channels for smart grid realization is investigated and a viable PLC infrastructure for smart grid communication network is proposed. Furthermore, to have a better understanding of the viability of powerline communication for the smart grid...

This brief will focus on enabling regulations for mini-grids, providing an overview of key issues, options, and good practices. While appropriate regulations are not all that is needed to spur mini-grid development, is usually one of the first obstacles that potential developers face and therefore the most urgent issue for governments. The authors draw on a case study of Tanzania, a pioneer in setting an enabling and light-handed regulatory framework for mini-grids. Given the urgency of leveraging private sector investments for reaching the universal access targets of the international sustainable energy for all projects, the authors also focus on regulatory issues relevant to private sector entrepreneurs and investors. Mini-grid entrepreneurs need to know that their investment of time and money will have a reasonable chance not just of being repaid but also of returning a profit. A clear and credible regulatory framework that makes and enforces fair and efficient decisions in a timely manner helps entrepreneurs make informed investment decisions. The key characteristics of such a framework...

With the accelerating adoption of electric vehicles, using the batteries in the existing vehicle fleet to discharge to the power grid when needed (vehicle-to-grid, V2G) provides a potential alternative for supplying grid support. This master project focused on the often-overlooked side of V2G, the energy efficiency, and compared V2G versus other grid support technologies in terms of their efficiencies and emissions. Given V2G is most suitable for regulation service, other available technologies serving regulation were selected for the comparison. The project adopted a fuel-to-grid scope when conducting the comparison among different grid support technologies, meaning the efficiency at which fuels are converted into final grid support, along with the associated emissions, were analyzed and compared. The comparison led to three major findings: (1) energy storage-based technologies achieve a lower fuel-to-grid efficiency than gas turbines do; (2) V2G is less efficient in delivering grid support than grid-dedicated battery banks and flywheels; (3) storage-based technologies, especially V2G, would significantly increase CO2, SO2, and NOx emissions.

In this paper, we describe a Grid abstraction framework that allows access to the Grid infrastructure using JavaScript while leveraging the power of current Grid middleware and upperware toolkits such as the Globus Toolkit and the Java Commodity Grid (CoG) Kit . The system is heavily based on Web 2.0 technologies and allows accessing the Grid through a Service-Oriented Architecture. An application interface in JavaScript is provided to enable developers to access Grid services from JavaScript. Moreover, our framework includes additional services to enable the creation of advanced Grid services. The availability of our framework simplifies not only the development of new services but also the development of advanced client side Grid applications. We demonstrate this ability while providing a mechanism to develop Grid workflows through advanced services and a graphical user interface defined in JavaScript. Overall, Grid developers will have another tool at their disposal that projects a simpler way to distribute and maintain software while at the same time being able to deliver quickly advanced interfaces and social services for the scientific community.; "JavaScript grid abstractions," Proceedings of the Grid Computing Environments (GCE) workshop.

Organizations in the Open Science Grid are motivated to provide services so that individual scientists can effectively execute data analysis jobs and take advantage of Grid resources. For success, these scientists will need to be able to monitor the execution status and application-level messages of their jobs that may run at any site within the Virtual Organization. In the Open Science Grid, the existing grid-wide tools provide abundant information about the whole system, but are geared towards Grid administrators, while information tailored towards individual users is not readily available except for the larger organizations that can afford to build their own tools. The User Centric Monitoring project addresses this gap by targeting a novel complete set of user-centric information including the status of a task of submitted jobs, queue positions, times of the start and finish, output and error messages, and reasons for failure. The toolkit is designed to provide flexible collection mechanisms and rich portlet-based presentation tool. This paper will describe the toolkit and portlet designs with a description of the most recent implementation progress.; "Portlets for user centric job and task monitoring for open science grid virtual organizations...

Rendered animations are a significant part of many student and research projects being done at Indiana University. Typically the rendering process is very computationally intensive, but it is allocated minimal computing resources. By creating a Condor pool out of all student computing labs we have created a large scale, homogeneous grid resource dedicated to the single purpose of rendering. By implementing a web portal based interface to submit and monitor rendering jobs the rendering system becomes independent of the end users architecture, OS, and even rendering package being used. This allows for a “learn once, run often” architecture despite the highly complex distributed computational backend. The web interface allows users to submit jobs with the needed parameters, monitor the progress of the job, and display finished frames of the animation. When the job finishes the render system notifies the user and will present a web based preview of the final movie, allowing the user to quickly assess the quality of the rendered results. The modular nature of the render system allows for easy upgrade and additions to the rendering packages offered. New rendering packages can typically be added within 24 hrs, without any changes to the user interface or workflow.; "Creating grid resources for use in undergraduate coursework...

Grid systems provide mechanisms for single sign-on, and uniform APIs for job submission and data transfer, in order to allow the coupling of distributed resources in a seamless manner. However, new users face a daunting barrier of entry due to the high cost of deployment and maintenance. They are often required to learn complex concepts relative to grid infrastructures (credential management, scheduling systems, data staging, etc). To most scientific users, running their applications with minimal changes and yet getting results faster is highly desirable, without having to know much about how the resources are used. Hence, a higher level of abstraction must be provided for the underlying infrastructure to be used effectively. For this purpose, as part of our prior work, we have developed the Opal toolkit for exposing applications on grid resources as simple Web services [1]. Opal provides a basic set of APIs that allows users to execute their deployed applications through graphical user interfaces, or via programmatic means. In this paper, we present our ongoing work to extend the Opal toolkit that enables the creation of an end-to-end infrastructure to dynamically leverage scientific applications on grid resources. In particular, we focus on the following two key extensions. We have developed a command-line syntax description language that can be published via the Opal interface. This enables the creation of dynamic Web forms for job submission...

We present a detailed description of the implementation of a library of Grid tag libraries and Grid beans for Grid Web portal development. Grid tags provide Java Server Faces (JSF) custom components for Grid services. They enable the definition of attributes to the Grid service parameters in a dynamic way embedded into JSF view pages. In addition, Grid beans provide client proxies to the Grid services. Grid tags and beans together provide a platform to develop Grid portlets easily. In addition to standard Grid job submission and remote file operation tags, we also provide management and monitoring capabilities for Grid tasks. This system can persistently store bean features and job parameters, which results in a permanent storage for archiving and reference.; ACM, IEEE
