This article outlines the requirements for useful models of biologic systems. Such models should fulfill three conditions: (i) suit the bottom-up data of the living system, not merely adhere to top-down logic; (ii) abet experimentation by stimulating new ideas for novel experiments; and (iii) engage the mind of the experimentalist with understandable, visual representations. Seven characteristi...

In this article we propose a methodology for implementing the behaviour of intelligent interface agents using a BDI (Believes, Desires, Intentions) model. This work is based on the architecture presented in (Garijo et al. 98). We aim to show that BDI schemes applied to intelligent interface agents design produce robust and intuitively designed applications. This work has been applied to a fully...

Atomistic modeling plays a critical role in advancing our understanding of microstructure evolution and mechanical properties. We present progresses in the theory and computation of ideal strength, dislocations activation processes and brittle fracture from the atomic perspective, in close connection with experiments and other levels of modeling. New discoveries are often made in the “virtual a...

This paper presents a novel implementation of an electromagnetically coupled patch antenna using air gap filled substrates to achieve the maximum bandwidth. We also propose an efficient modeling technique using the FDTD method which can substantially reduce the simulation cost for modeling the structure. The simulated results have been compared with measurement to show the broadband behavio...

The combination of programmatic theory and structural equation modeling (SEM) can act as the basic intellectual machinery for designing and evaluating behavioral interventions. As an example of the integration, we consider a case study of a randomized experiment to reduce sexual risk taking, the WINGS Project. Barriers to combining systematic use of SEM with programmatic theory for program impr...

The continued and increasing use of online asynchronous learning (OAL) environments for training raises the question whether and to what extent behavior modeling, the most effective training method in live instruction, will prove to be effective in OAL environments. This article analyzes the effect of applying behavior modeling training in an OAL environment. Behavior modeling training can be d...
