One of the prime reasons inhibiting the widespread use of discrete-event simulation in construction planning is the absence of appropriate visual communication tools. Visualizing modeled operations in 3D is arguably the best form of communicating the logic and the inner working of simulation models and can be of immense help in establishing the credibility of analyses. New software development ...

BACKGROUND For many patients admitted to the intensive care unit (ICU), preferences for end-of-life care are unknown, and clinicians and substitute decision-makers are required to make decisions about the goals of care on their behalf. We conducted a systematic review to determine the effect of structured communication tools for end-of-life decision-making, compared to usual care, upon the numb...

Although diagrams are considered as effective personal tools for solving problems, applied research in education has identified a widespread problem: that students lack spontaneity in diagram use. One way to address this problem was reported by Uesaka and Manalo (2007): their findings indicate the effectiveness of using peer instruction to enhance students’ spontaneous use of diagrams. However,...

This study examines the use of instant messaging (IM) for student-teacher communication in distance education (DE) courses. IM is a simple Internet communication tool that may reduce the sources of dissatisfaction cited by many DE students and improve their performance, perception of the amount of information learned, and satisfaction with a class. As a relatively synchronous communication tool...

Following the trend in computer and network architecture towards smaller and lighter devices that are more or less constantly connected to the Internet through wireless access networks, mobile computing has emerged as a promising means to improve the possibilities of distributed collaborative teamwork. However, the mobility support implemented in state of the art collaboration software has hith...

The Plebanski–Demianski solution is a very general axially symmetric analytical solution of Einsteins field equations generalizing the Kerr solution. This solution depends on seven parameters, the mass, a rotation parameter, a cosmological constant, NUT parameter, electric and magnetic charges, and an acceleration. In this paper we present a general description of matter wave interferometry in ...

Due to globalization and environmental challenges, there is a growing interest in adopting collaborative technologies to support distributed virtual enterprises to work as virtual teams, reducing time, cost and need for travel. This paper presents the approach taken by the CoSpaces project [1] in developing a collaborative technology platform for distributed engineering organizations. In partic...
