In this paper we explore the benefits that a virtual agent could provide to an e-Learning platform. The system uses Natural Language techniques as a basis, which makes it capable of elaborating a flexible answer according to the student requirements. The Software procedures to perform these task are also introduced s.

AbstrAct The Business Process Execution Language for Web Services (BPEL) is an emerging standard for specifying the behaviour of Web services at different levels of details using business process modeling constructs. It represents a convergence between Web services and business process technology. This chapter introduces the main concepts and constructs of BPEL and illustrates them by means of ...

Concerns such as compliance, auditing, business activity monitoring or accounting need to be addressed in the early stages of modeling and not only at the implementation or execution levels. Mostly, such concerns are modeled as part of the normal flow in business process models. However, the crosscutting nature of such concerns leads to scattered and tangled models. When we try to model busines...

Organizations of today are becoming ever more focused on their business processes. This has resulted in an increasing interest in business process patterns, which can be used in order to understand where from one can adopt best practices, or how to build computer systems supporting business processes. However, to fully exploit patterns, they need to be defined in a structured, and even formal w...

Service oriented modeling and deployment of biological processes allow these processes to be published, discovered and, most importantly, invoked on the Web. This in-place invocation capability provides the basis for simulation based validation and predictive analysis of discovered pathways linking published services. We present a Web service mining framework that enables the discovery and vali...

Modelling of machining operations is a key issue in today’s manufacturing. Reliable and effective models are needed in order to plan and control machining processes. The paper gives a short overview of modelling approaches frequently used in manufacturing with emphasis on the workpiece quality. Classical, e.g. differential equation-based techniques focus on the special aspects of machining (e.g...

Economic globalization leads to complex decentralized company structures calling for the extensive use of distributed IT-systems. The business processes of a company have to reflect these changes of infrastructure. In particular, due to new electronic applications and the inclusion of a higher number of — potentially unknown — persons, the business processes are more vulnerable against maliciou...

Background: Infertility is a stressful event for both couples; therefore investigation of coping styles can be helpful to show how to improve mental health in couple infertile. The aim of this study was to compare individual coping processes of men and women in infertile couples. Materials and Methods: Study participants were comprised of 142 men and women who were referred to Fatemeh Alzahra F...

This paper proposes an execution order control method of coarse grain distributed processes for parallelizing compiler on distributed computer environment. Currently proposed execution order control algorithms are designed for the basic-block-oriented distributed processes. However, we adopted an process generation algorithm based on function-oriented distributed processes and therefore propose...
