Estrutura básica do MicroArray Gene Expression Markup Language - MAGE-ML.

Um dos objetivos da Rede Genômica Animal é a identificação de genes que contribuam para o melhoramento de características de interesse econômico em animais de produção. Uma das ferramentas para prospecção e análise desses genes é o Microarranjo de DNA, uma técnica que permite avaliar a expressão gênica em condições específicas. Apesar de seu uso amplamente difundido na comunidade científica, os procedimentos e as informações de experimentos nem sempre são padronizados, a despeito dos esforços na criação de uma linguagem padrão como o MAGE-ML. Este documento visa apresentar o padrão MAGE-ML para aqueles que ainda não se utilizam desse recurso e gostariam de aprender um pouco a respeito.

Design of a Web interface for anatomical images

Interactive documents for use with the World Wide Web have been developed for viewing multi-dimensional radiographic and visual images of human anatomy, derived from the Visible Human Project. Emphasis has been placed on user-controlled features and selections. The purpose was to develop an interface which was independent of host operating system and browser software which would allow viewing of information by multiple users. The interfaces were implemented using HyperText Markup Language (HTML) forms, C programming language and Perl scripting language. Images were pre-processed using ANALYZE and stored on a Web server in CompuServe GIF format. Viewing options were included in the document design, such as interactive thresholding and two-dimensional slice direction. The interface is an example of what may be achieved using the World Wide Web. Key applications envisaged for such software include education, research and accessing of information through internal databases and simultaneous sharing of images by remote computers by health personnel for diagnostic purposes.

Information sharing in Onesocialweb using a multiple profile manager to better informed medical decision making processes

The study shows an alternative solution to existing efforts at solving the problem of how to centrally manage and synchronise users’ Multiple Profiles (MP) across multiple discrete social networks. Most social network users hold more than one social network account and utilise them in different ways depending on the digital context (Iannella, 2009a). They may, for example, enjoy friendly chat on Facebook1, professional discussion on LinkedIn2, and health information exchange on PatientsLikeMe3 In this thesis the researcher proposes a framework for the management of a user’s multiple online social network profiles. A demonstrator, called Multiple Profile Manager (MPM), will be showcased to illustrate how effective the framework will be. The MPM will achieve the required profile management and synchronisation using a free, open, decentralized social networking platform (OSW) that was proposed by the Vodafone Group in 2010. The proposed MPM will enable a user to create and manage an integrated profile (IP) and share/synchronise this profile with all their social networks. The necessary protocols to support the prototype are also proposed by the researcher. The MPM protocol specification defines an Extensible Messaging and Presence Protocol (XMPP) extension for sharing vCard and social network accounts information between the MPM Server, MPM Client, and social network sites (SNSs). . Therefore many web users need to manage disparate profiles across many distributed online sources. Maintaining these profiles is cumbersome, time-consuming, inefficient, and may lead to lost opportunity. The writer of this thesis adopted a research approach and a number of use cases for the implementation of the project. The use cases were created to capture the functional requirements of the MPM and to describe the interactions between users and the MPM. In the research a development process was followed in establishing the prototype and related protocols. The use cases were subsequently used to illustrate the prototype via the screenshots taken of the MPM client interfaces. The use cases also played a role in evaluating the outcomes of the research such as the framework, prototype, and the related protocols. An innovative application of this project is in the area of public health informatics. The researcher utilised the prototype to examine how the framework might benefit patients and physicians. The framework can greatly enhance health information management for patients and more importantly offer a more comprehensive personal health overview of patients to physicians. This will give a more complete picture of the patient’s background than is currently available and will prove helpful in providing the right treatment. The MPM prototype and related protocols have a high application value as they can be integrated into the real OSW platform and so serve users in the modern digital world. They also provide online users with a real platform for centrally storing their complete profile data, efficiently managing their personal information, and moreover, synchronising the overall complete profile with each of their discrete profiles stored in their different social network sites.

The potential of XML technology as an answer to the data interchange problems of the construction industry

The complex supply chain relations of the construction industry, coupled with the substantial amount of information to be shared on a regular basis between the parties involved, make the traditional paper-based data interchange methods inefficient, error prone and expensive. The successful information technology (IT) applications that enable seamless data interchange, such as the Electronic Data Interchange (EDI) systems, have generally failed to be successfully implemented in the construction industry. An alternative emerging technology, Extensible Markup Language (XML), and its applicability to streamline business processes and to improve data interchange methods within the construction industry are analysed, as is the EDI technology to identify the strategic advantages that XML technology provides to overcome the barriers to implementation. In addition, the successful implementation of XML-based automated data interchange platforms for a large organization, and the proposed benefits thereof, are presented as a case study.

Selective dissemination of XML documents based on genetically learned user model and Support Vector Machines

Extensible Markup Language ( XML) has emerged as a medium for interoperability over the Internet. As the number of documents published in the form of XML is increasing, there is a need for selective dissemination of XML documents based on user interests. In the proposed technique, a combination of Adaptive Genetic Algorithms and multi class Support Vector Machine ( SVM) is used to learn a user model. Based on the feedback from the users, the system automatically adapts to the user's preference and interests. The user model and a similarity metric are used for selective dissemination of a continuous stream of XML documents. Experimental evaluations performed over a wide range of XML documents, indicate that the proposed approach significantly improves the performance of the selective dissemination task, with respect to accuracy and efficiency.

Sistema seguro de votação eletrônica multi-células

Em uso desde a Grécia antiga e atualmente massificado na maioria dos países do mundo, o sistema de votação tradicional baseado em cédulas de papel possui diversos problemas associados à segurança, tais como dificuldades para evitar coerção do eleitor, venda do voto e substituição fraudulenta do eleitor. Além de problemas de usabilidade que acarretam erros de preenchimento da cédula e um processo de apuração lento, que pode durar dias. Ao lado disso, o sistema tradicional não fornece a contraprova do voto, que permite ao eleitor conferir se o seu voto foi corretamente contabilizado na apuração. Inicialmente acreditou-se que a informatização do sistema de votação resolveria todos os problemas do sistema tradicional. Porém, com a sua implantação em alguns países o sistema de votação eletrônica não mostrou-se capaz de fornecer garantias irrefutáveis que não tivesse sido alvo de alterações fraudulentas durante o seu desenvolvimento ou operação. A má reputação do sistema eletrônico está principalmente associada à falta de transparência dos processos que, em sua maioria, não proporcionam a materialização do voto, conferido pelo eleitor para fins de contagem manual, e nem geram evidências (contraprova) da correta contabilização do voto do eleitor. O objetivo deste trabalho é propor uma arquitetura de votação eletrônica que integra, de forma segura, o anonimato e autenticidade do votante, a confidencialidade e integridade do voto/sistema. O sistema aumenta a usabilidade do esquema de votação baseado em "Três Cédulas" de papel, implementando-o computacionalmente. O esquema oferece maior credibilidade ao sistema de votação através da materialização e contraprova do voto, resistência à coerção e ao comércio do voto. Utilizando esquemas de criptografia assimétrica e segurança computacional clássica, associado a um sistema de auditoria eficiente, a proposta garante segurança e transparência nos processos envolvidos. A arquitetura de construção modular distribui a responsabilidade entre suas entidades, agregando-lhe robustez e viabilizando eleições em grande escala. O protótipo do sistema desenvolvido usando serviços web e Election Markup Language mostra a viabilidade da proposta.

Performance assessment of XACML authorizations for supply chain traceability web services

Service-Oriented Architecture (SOA) and Web Services (WS) offer advanced flexibility and interoperability capabilities. However they imply significant performance overheads that need to be carefully considered. Supply Chain Management (SCM) and Traceability systems are an interesting domain for the use of WS technologies that are usually deemed to be too complex and unnecessary in practical applications, especially regarding security. This paper presents an externalized security architecture that uses the eXtensible Access Control Markup Language (XACML) authorization standard to enforce visibility restrictions on trace-ability data in a supply chain where multiple companies collaborate; the performance overheads are assessed by comparing 'raw' authorization implementations - Access Control Lists, Tokens, and RDF Assertions - with their XACML-equivalents. © 2012 IEEE.

基于扩展XACML的策略管理

在XACML（extensible access control markup language）和其管理性策略草案的基础上，针对目前XACML访问控制框架的特点，提出将XACML策略管理权限判定归结为利用委托策略对一个委托判定请求的判定，使用XML（extensible markup language）模式定义了此委托判定请求语法，描述了将策略管理请求规约为一个委托判定请求的过程，以及根据委托策略进行委托判定请求的判定过程，通过这种方法可以利用委托策略，对策略管理请求是否有效进行判断，从而实现基于扩展XACML的策略管理。
