The UML 2 Activity Diagram is designed for modelling business processes, but does not yet include any concepts for modelling process goals and their measures. We extend the UML 2 Activity Diagram with process goals and performance measures to make them conceptually visible. Additionally, we provide a mapping to BPEL to make the measures available for execution and monitoring. This profile and i...

We consider the number of linear extensions of an N-free order P . We give upper and lower bounds on this number in terms of parameters of the corresponding arc diagram. We propose a dynamic programming algorithm to calculate the number. The algorithm is polynomial if a new parameter called activity is bounded by a constant. The activity can be bounded in terms of parameters of the arc diagram....

Since business workflows are closely related to enterprise performance, successfule execution of workflow is a critical driving force for strategic advantages of enterprise. Therefore, it is quite essential to customer satisfaction and productivity enhancement that structural errors in workflow instances must be detected and their performance must be evaluated before their enactments. For a str...

Japan is no exception among developed countries facing healthcare system problems due to aging and low birthrate as the number of possible patients increases and health care worker numbers shrink. The introduction of high tech medicine has increased the amount of knowledge to be learned by novice nurses. Although vast amounts of implicit knowledge have accumulated among nursing practitioners, t...

This paper introduces an evolution to classical workflow that allows more flexible execution of processes while retaining its simplicity. On the one hand it allows to describe processes in the same way that they are in design and engineering manuals. On the other hand it allows to control these processes in a way that is close to the way they are actually enacted. This evolution is based on the...

Student models for Intelligent Computer Assisted Language Learning (ICALL) have largely focused on the acquisition of grammatical structures. In this paper, we motivate a broader perspective of student models for ICALL that incorporates insights from current research on second language acquisition and language testing. We argue for a student model that includes a representation of the learner’s...

This paper describes the design of the pedagogical feedbacks in Diagram, a learning environment for UML object-oriented modeling. The project is rooted in several years of teaching practice and actual diagrams produced by novice students. Diagram is based upon an interaction framework that supports the learner’s metacognitive activity. It includes a diagnosis module which compares the student d...

Alzheimer's disease (AD) is a neurodegenerative disorder in which there is a decline of cholinergic function. The symptomatic AD treatment involves the use of ChEIs (cholinesterase inhibitors) as rivastigimine, a dual inhibitor. The human butyrylcholinesterase (BChE) is an enzyme that has specific roles in cholinergic neurotransmission and it has been associated with AD. In the serum, BChE is f...

Children with attention-deficit hyperactivity disorder (AD/HD) consistently perform worse on executive function (EF) tasks relative to those without AD/HD. Physical activity has a small effect on cognition in children and may be particularly beneficial for children with AD/HD by impacting fundamental EF deficiencies that characterize this disorder. The purpose of this study was to explore the e...

A system is introduced which automatically generates implementation code from the object and dynamic models of an application. We found that the behavior of active objects can well be represented by activity diagrams rather than state diagrams. The paper first explains our approach to convert state diagrams as well as activity diagrams into implementation code. The paper then describes our syst...
