Abstract:

The usage of cloud computing in order to move away from local servers and infrastructure have grown enormously the last decade. The ability to quickly scale capacity of servers and their resources at once when needed is something that can both be a price saver for companies and help them deliver high end products that will function correctly at all times even under heavy load to their customers. To meet todays challenges, one of the strategic directions of Attentec, a software company located in Linköping, is to examine the world of cloud computing in order to deliver robust and scalable appli

Abstract:

With the emergence of the Web and its pervasive intrusion on individuals, organizations, businesses etc., people now realize that they are living in a digital environment analogous to the ecological ecosystem. Consequently, no individual or organization can ignore the huge impact of the Web on social well-being, growth and prosperity, or the changes that it has brought about to the world economy, transforming it from a self-contained, isolated, and static environment to an open, connected, dynamic environment. Recently, the European Union initiated a research vision in relation to this ubiquit

Abstract:

This study examined the perspectives of agencies providing career development services in Canada concerning the current state of efficacy assessment. The central question guiding this research was: How do representatives of career services agencies perceive their evaluation practices and the results they are obtaining? A total of 147 (n=147) agency representatives participated in an on-line survey. The data obtained through the use of this survey were analyzed using a mixed methods design - methods included frequency analysis, Chi square analysis and qualitative methods (to conduct content ana

Web Service technology is one of the most rapidly developing contemporary technologies. Nowadays, Web Services are being used by a large number of projects and academic studies all over the world. As the use of Web service technology is increasing, it becomes harder to find the most suitable web service which meets the Quality of Service (QoS) as well as functional requirements of the user. In addition, quality of the web services (QoS) that take part in the software system becomes very important.

Abstract:

In future service markets a selection of functionally equal services is omnipresent. The evolving challenge, finding the best-fit service, requires a distinction between the non-functional service characteristics (e.g., response time, price, availability). Service providers commonly capture those quality characteristics in so-called Service Level Agreements (SLAs). However, a service selection based on SLAs is inadequate, because the static SLAs generally do not consider the dynamic service behaviors and quality changes in a service-oriented environment. Furthermore, the profit-oriented servic

Abstract:

Business transactions (a.k.a., business conversations) are series of message exchanges that occur between software applications coordinating to achieve a business objective. Web service has been proven to be a promising technology in supporting business transactions. Business transaction can either be long-running or short-lived. A transaction whether in a database or web service paradigm consists of an “all-or-nothing” property. A transaction could either succeed or fail. Web Service Atomic Transactions (WS-AT) is a specification that currently supports Two-Phase Commit (2PC) protocol in a sh

Abstract:

Most epidemiological systems described in the literature are built for evaluation and analysis of specific diseases, such as Influenza-like-illness. The modeling environments that support these systems are implemented for specific diseases and epidemiological models. Hence they are not reusable or extendable. This thesis focuses on the design and development of an integrated analytical environment with flexible data integration methodologies and multi-level web services for evaluation and forecasting of various epidemics in different regions of the world. The environment supports analysis

Abstract:

The success of web services is changing the way in which software is designed, developed, and distributed. The increasing diffusion of software in the form services, available as commodities over the Internet, has en- abled business scenarios where processes are implemented by composing loosely-coupled services chosen at runtime. Services are in fact continuously re-designed and incrementally developed, released in heterogeneous and distributed environments, and selected and integrated at runtime within external business processes. In this dynamic context, there is the need of solutions suppor

Abstract:

Esta dissertação de mestrado aborda um estudo sobre a caracterização de cargas de trabalho para Web services por meio da análise de Documentos WSDL (Web Service Description Language). Esses documentos, que representam a interface para os serviços, foram obtidos na Web e seus conteúdos analisados estatisticamente. A metodologia utilizada para alcançar a caracterização desejada, constitui-se da coleta e análise dos dados de 1346 arquivos WSDL válidos. O resultado do estudo proposto nesta dissertação contribui para a avaliação de desempenho no que diz respeito a caracterizar os diversos aspectos

Abstract:

The Service Worker is a programmable proxy that allows the clients to keep offline parts of websites or even the whole domains, receive push notifications, have back-ground synchronization and other features. All of these features are available to the user without having to install an application - the user only visits a website. The service worker has gained popularity due to being a key component in the Progressive Web Applications (PWAs). PWAs have already proven to drastically increase the number of visits and the duration of browsing for websites such as Forbes [1], Twitter [2], and many

Abstract:

Este projeto de mestrado tem como objetivo principal construir Web services de modo a permitir a avaliação de desempenho de uma arquitetura denominada WSARCH. A arquitetura WSARCH foi proposta de modo a prover uma infra-estrutura de Web services considerando aspectos de qualidade de serviço (QoS). Este projeto contribui diretamente com o desenvolvimento desta arquitetura, além de auxiliar na sua validação e na realização de estudos de desempenho de suas funcionalidades. Trabalhos preliminares de pesquisa foram desenvolvidos de forma que, além de auxiliar no desenvolvimento da WSARCH, também co

Abstract:

Over the last years, online learning has gained significant popularity, and this trend is expected to continue in the future. Online learning is a multi-dimensional activity where each dimension should be adequately supported by an online learning system to provide a fruitful learning experience to its users. <p> Similar to online learning, a particular approach in the way systems are designed has gained increasing popularity over the last years as a result of the emergence of the computer network. Systems have started to be envisioned as integrated collections of components that are deployed

Abstract:

Electronic government (e-Government) in terms of public service delivery and administration has endured signification transformation over the last decade. More recently, modern second generation web technologies (Web 2.0) have started to be used to deliver e-Government. However, this in turn has brought about additional challenges. By its nature, Web 2.0 is more interactive than the traditional model of information provision or creation of digital services and as such opens up a new set of benefits, costs and risks to those who make use of it as part of their e-Government approach.
