A service provider is interested in precise service cost calculations. Reliable cost information is required for sound economic decisions and provides valuable input for human resource management. But, without accounting for customer involvement, service costing is not accurate. Existing costing methods like Activity-Based Costing (ABC) have given too less attention on customer introduced uncertainty. To overcome this problem and to increase reliability we measure customer’s individuality (e.g. experience, company size or speed of internet connection) and integrate it into cost accounting. To consider these individual aspects we have developed a generalized approach based on four customer factor classes (co-creation, information, technology and experience). We have integrated the customer factor classes into our three layered concept, which consists of the layers customer factors, customer factor classes and Time-Driven Activity-Based Costing (TDABC). With this three layered approac...

Resumo. Uma promissora solução de gestão, coordenação e orquestração de serviços electrónicos é o uso dos sistemas de gestão de workflows. Embora várias linguagens para modelar workflows, sistemas para a gestão de workflows e técnicas de análise formais tenham sido estudadas de um modo extensivo, a investigação de métodos para auxiliar o desenho de workflows é praticamente inexistente. O propósito deste trabalho é apresentar uma aplicação, denominada de Poseidon, para ajudar os analistas e designers de ...

Neste trabalho, pretende-se introduzir o enquadramento que permitirá a criação de empresas compostas por diversas entidades especializadas em dominos previamente definidos seguindo uma política just-in-time. A agregação temporária tem por objectivo final a realização de uma tarefa inicialmente definida, com o auxílio e cooperação de todas as entidades envolvidas no processo. O aspecto social da cooperação e coordenação, que estará patente entre as diversas entidades, terá o apoio de infraestruturas de ...

To make semantic Web services accessible to users, providers use registries to publish them. Unfortunately, the current registries use discovery mechanisms which are inefficient, as they do not support discovery based on the semantics of the services and thus lead to a considerable number of irrelevant matches. Semantic discovery and matching of services is a promising approach to address this challenge. This paper presents an algorithm to match a semantic Web service request described with SAWSDL against ...

This professional book provides a series of case studies which give examples of real benefits to be derived from the adoption of semantic web based ontologies in real world situations, such as telecommunication, B2B integration, tourism, education and more. The book is designed to create platforms for bringing experts together (key government representatives, industry and academia) from different countries, and to compile the most recent use of semantics and ontologies. de Web provides.

Consumers today are making increasing demands on the quality of products and services offered by businesses worldwide and organizations such as educational institutions are no exception to the trend. Nevertheless, many institutions, including universities, seem to be unaware of this, continuing to maintain structures and methods of working which no longer correspond to the emerging demands of the market. In this project we have aimed to counter this tendency by introducing a prototype system of workflow management ...

Service providers are increasingly forced to cooperate to strengthen their core competencies and to create partner networks to offer required services. In order to facilitate the collaboration process, business ecosystems have been building which allow service providers to offer their own as well as combined e-services with other providers over the Internet. This paper introduces the Inter-enterprise Service Engineering methodology (ISE) which has been developed in the Texo use case1 of the Theseus project2 and provides a ...

Quando estabelecidos sobre redes informáticas de longa distância os sistemas de criação musical colaborativos comportam um problema critico: a latência da rede, que é um impedimento à comunicação musical em tempo real. Num estudo recente, foi estabelecida a relação entre tolerância à latência eo ritmo musical. Este resultado emergiu de uma experiência levada a cabo pelos autores deste artigo, na qual foram aplicadas condições simuladas de latência de rede à performance de diferentes músicos enquanto tocavam ...

O carcinoma de células de Merkel é um tumor neuro-endócrino pouco frequente localizado principalmente nas áreas foto-expostas de adultos de idade avançada. Fatores como o elevado risco de recidiva local e doença metastática somados a um diagnóstico frequentemente tardio, são determinantes de um mau prognóstico. O exame dermatoscópico desta lesão que se caracteriza pela presença de múltiplos vasos atípicos e “áreas vermelho-leitosas”, pode ser uma ferramenta útil para o estabelecimento precoce e rápido de uma suspeita diagnóstica permitindo o tratamento atempado. Os autores reportam um caso de uma doente de 71 anos com um carcinoma de células de Merkel no membro inferior direito em que os achados dermatoscópicos identificaram um elevado índice de suspeição permitindo a excisão do tumor em tempo útil. Descrevem-se os principais padrões dermatoscópicos observados e os diagnósticos diferenciais a considerar.
