A self-healing architecture for Web service-based applications

Web service-based application is an architectural style, where a collection of Web services communicates to each other to execute processes. With the popularity increase of developing Web service-based application and once Web services may change, in terms of functional and non-functional Quality of Service (QoS), we need mechanisms to monitor, diagnose, and repair Web services into a Web Application. This work presents a description of self-healing architecture that deals with these mechanisms. Other contributions of this paper are using the proxy server to measure Web service QoS values and to employ some strategies to recovery the effects from misbehaved Web services. © 2008 IEEE.

Prospective analysis about the world wide strategy of commercial vehicles development

The main objective of this paper is to make a prospective analysis about the tendencies of the world wide strategies of commercial vehicles development, in relation of the current local and international scenery. It has been done a research by using the Delphi method, which consists into regulate, systematically, the presentation of questions about a specified problem to a group of specialists. In order to guarantee more representative data, it has been adopted three distinct groups: academics, OEMs managers and Tier 1 suppliers managers. The results showed that the three mentioned groups have similar opinion about the necessity of having a product development in the subsidiaries companies; also it has been pointed the necessity of having more taylor made vehicles, due to the intrinsic characteristics of this industry segment.

A video-based biometric authentication for e-learning web applications

In the last years there was an exponential growth in the offering of Web-enabled distance courses and in the number of enrolments in corporate and higher education using this modality. However, the lack of efficient mechanisms that assures user authentication in this sort of environment, in the system login as well as throughout his session, has been pointed out as a serious deficiency. Some studies have been led about possible biometric applications for web authentication. However, password based authentication still prevails. With the popularization of biometric enabled devices and resultant fall of prices for the collection of biometric traits, biometrics is reconsidered as a secure remote authentication form for web applications. In this work, the face recognition accuracy, captured on-line by a webcam in Internet environment, is investigated, simulating the natural interaction of a person in the context of a distance course environment. Partial results show that this technique can be successfully applied to confirm the presence of users throughout the course attendance in an educational distance course. An efficient client/server architecture is also proposed. © 2009 Springer Berlin Heidelberg.

Software architecture for web-based project management system

This article presents software architecture for a web-based system to aid project managing, conceptually founded on guidelines of the Project Management Body of Knowledge (PMBoK) and on ISO/IEC 9126, as well as on the result of an empiric study done in Brazil. Based on these guidelines, this study focused on two different points of view about project management: the view of those who develop software systems to aid management and the view of those who use these systems. The designed software architecture is capable of guiding an incremental development of a quality system that will satisfy today's marketing necessities, principally those of small and medium size enterprises.

Acessibilidade em Ambientes Informacionais Digitais

The current nature of World Wide Web (Web), which highlights the collaborative participation of users in some digital information environments, lead to development of guidelines with a focus on Inclusive Digital Information Architecture for a different audiences in multiples informational ambiences. This research proposes guidelines for a inclusive digital information environment, aiming to identify the elements of accessibility that allow the promotion of inclusion digital information, in order to highlight the references of the Architecture of Digital Information, the international recommendations and the structures representation of information (specially accessibility attributes), with the look of Information Science and New Technologies of Information and Communication. The thesis is as to the need to develop methodologies with guidelines that contemplate the elements of digital accessibility focused on the task of the user. The research problem is that actual methodologies and recommendations used for the development of digital information environments do not cover all the elements of accessibility with a focus on user needs. The proposition is to present, through a methodological approach (exploratory and descriptive), a theoretical-methodological proposal to promote elements of digital accessibility to the development of digital information environments, for users with or without special needs. The overall objective of this study is to contribute to the development of inclusive digital information environments, in perspective of union of theories, recommendations and technologies for the development of digital accessibility guidelines. In a theoretical dimension, the research covers a critical review of the specialized literature in the areas of Information Science and Computer Science and, in the applied part, the analysis and development of a proposal of guidelines for the architecture of a digital information environment with accessibility.

Use of classification in organizing and searching the web

The traditional characteristics and challenges for organizing and searching information on the World Wide Web are outlined and reviewed. The classification features of two of these methods, such as Google, in the case of automated search engines, and Yahoo! Directory, in the case of subject directories are analyzed. Recent advances in the Semantic Web, particularly the growing application of ontologies and Linked Data are also reviewed. Finally, some problems and prospects related to the use of classification and indexing on the World Wide Web are discussed, emphasizing the need of rethinking the role of classification in the organization of these resources and outlining the possibilities of applying Ranganathan's facet theories of classification.

O citar no Twitter: o caso de Clarice Lispector

The phenomenon of the World Wide Web, the Internet, has revolutionized the way we live in a contemporary relevance. The relationships among people have changed since the media also changed: the cyberspace has been established as an important vehicle of communication in which different languages, cultures and peoples coexist. Within the virtual space there are several fica possibilities for communication, interaction, fun, knowledge etc. Everything happens extremely quickly. An interesting example of that are blogs that, to survive virtuality, require constant updating. It has become interesting to notice the factor of personal expressiveness taking a new shape in the context of network, before being seen in elements such as diaries, poetry, artistic production or debate. The chances and, thus, the need to find people to interact and to share interests has taken a gigantic proportion, and, in this way, sources of audiovisual and reading activities are always in vogue, being shared every second. Blogging can be about different subjects, but what is perceived on all blogs is the strong trace of written text is always presented. Twitter has established itself as a microblogging network for the expression of dynamism, information sharing and interaction. Thus, it was interesting to approach the manner language is expressed in these microblogs thinking about the way that literary discourse is constructed when is seen, on quotations, in the context of this social network: Twitter. Being able to attest the great increase on the occurrences of quotes from different literary genres, it was useful to pay attention to this fact. In Brazil, Twitter has thousands of users, fans and readers, that rewrite and quote authors. The number of quotations is so abundant that it has popularized several Brazilian writers, such as: Clarice Lispector and Caio Fernando Abreu; authors that are frequetenly quoted. So, we made usage of semiotic studies of the French line. In...
