This paper introduces the SDBC approach. It aligns business process modeling and software specification. They are aligned in a component-based way. In particular, business components are identified and reflected in the software specification. The business components are identified considering the rich semantic and language/communicative expressiveness of current business systems. This is claime...

Fine grained behavioural models of humans in a context, such as associates in an organization or a consumer group may allow us to both better understand existing behaviour as well as what would happen given various situations. We have been working on a behaviour compositional approach to this problem which creates realistic agent behaviour models that when run as a simulation allows us to under...

In this paper we present an Information Retrieval System (COSYDOR) designed for sightless students or researchers, to improve their access to scientific information. Our approach consists in reusing search instances in order to help these users when querying COSYDOR. Thus, In the first part we define a search instance model, including our proposed user model. Then we present our approach of Cas...

The value of information technology (IT) is often realized when continuously being used after users’ initial acceptance. However, previous research on continuing IT usage is limited for dismissing the importance of mental goals in directing users’ behaviors and for inadequately accommodating the group context of users. This in-progress paper offers a synthesis of several literature to conceptua...

Spatial skills predict students’ success in STEM domains. This paper aims to better understand the difficulties of students with low spatial skills in using interactive graphical representations. I present a mediation analysis with test and log data from 117 students who worked with an intelligent tutoring system for chemistry. The analysis is based on (1) a knowledge component model that descr...

This paper deals with effective calculation of moments of binary images. Recently, Spiliotis and Mertzios (see ibid., vol.7, p.1609-15, Nov. 1998) published a method based on image block representation (IBR). We propose a refinement of their method which yields exact results and performs even more effectively.

Developing industrial Case–Based Reasoning (CBR) applications has become much easier since the advent of the INRECA methodology [BBG99] which employs software process modelling techniques [VR95] to describe CBR system development tasks and uses the experience factory approach [BCR94] to store experience gained in the realization of CBR projects. empolis (and its former INRECA project partner ka...

Experimental data from a spatially explicit dynamic commons dilemma experiment is used to empirically ground an agent-based model. Four distinct patterns are identified in the data. Two naïve models, random walk and greedy agents, do not match the patterns. A more comprehensive model is presented that explains how agents make movement and harvest decisions. Using pattern oriented modeling the p...

This paper describes an automatic annotation, or autotagging, algorithm that attaches textual tags to 3D models based on their shape and semantic classes. The proposed method employs Manifold Ranking by Zhou et al, an algorithm that takes into account both local and global distributions of feature points, for tag relevance computation. Using Manifold Ranking, our method propagates multiple tags...

We present a pulmonary alveolar epithelial cell model and its simulation results aimed to provide mechanistic insight into biological principles that underlie alveolar morphogenesis in vitro. Primary human alveolar type II cells in 3D cultures have been shown to undergo processes of cell migration and aggregation to form hollow cystic structures that resemble human lung alveoli. Although variou...
