Virtual team in a project within an organization could achieve optimize project performance by acquiring appropriate human resources, coordination, communication and regular performance evaluation. According to the literature many ICT tools will collaborate to manage virtual teams, but still most of the projects lead to failure in the software industry. Aim of this research is to discover the m...

We consider a design problem in which a one-dimensional array of sensors, connected via a wireless network, is used to track a moving vehicle. Individual sensors occasionally lose the vehicle, but can relocate it with aid from neighboring sensors. Communication between sensors is costly, so we accordingly optimize the communication protocol within a class of broadcast-type protocols to maximize...

We propose an approach to compute navigation instructions on mobile devices carried by people during a building evacuation in order to guide them to safe areas or exits. The mobile devices form an ad hoc network via local communication links and use this network to collect information about the current evacuation situation. This information is used for path planning in order to optimize escape ...

Communication failures are a significant contributor to medical errors that harm patients. Critical care delivery is a complex system of inter-professional work that is distributed across time, space, and multiple disciplines. Because health-care education and delivery remain siloed by profession, we lack a shared framework within which we discuss and subsequently optimize patient care. Further...

The Message Passing Interface (MPI) is the most commonly used application programming interface for process communication on current large-scale parallel systems. Due to the scale and complexity of modern parallel architectures, it is becoming increasingly difficult to optimize MPI libraries, as many factors can influence the communication performance. To assist MPI developers and users, we pro...

During humanitarian response efforts, the mass media serves as the primary informational intermediary informing donors, policy makers, and the non-affected public. A lack of professional standards within the current culture of journalism, the politics of media ownership, and media manipulation by governments has distorted reporting on humanitarian crises, with possible detrimental effects on re...

In the distributed environment where a query involves several heterogeneous sources, communication costs must be taken into consideration. In this paper we describe a query optimization approach using dynamic programming technique for set integrated heterogeneous sources. The objective of the optimization is to minimize the total processing time including load processing, request rewriting and ...

This paper demonstrates the first tera-scale performance of Intel © Xeon Phi TM coprocessors on 1D fft computations. Applying a disciplined performance programming methodology of sound algorithm choice, valid performance model, and well-executed optimizations, we break the tera-flop mark on a mere 64 nodes of Xeon Phi and reach 6.7 tflops with 512 nodes, which is 1.5× than achievable on a same ...

The importance of computer applications and telecommunication services relying on ee-cient multi-destination communication is growing rapidly. It is now likely that a signiicant portion of the overall traac in future communication environments will be of the multi-destination type. At the same time, lightwave technology is emerging as a promising candidate for implementing the next generation o...

This paper presents a general framework for optimal task reallocation in heterogeneous distributed computing systems (DCSs). The framework relies on a rigorous analytical model for the stochastic execution time of a workload. The model takes into account the heterogeneity and randomness of both service times and communication delays, an arbitrary task-reallocation policy as well as the stochast...
