Grids aim at exploiting synergies that result from the cooperation of autonomous distributed entities. The synergies that result fromGrid cooperation include the sharing, exchange, selection, and aggregation of geographically distributed resources such as computers, databases, software, and scientific instruments for solving large-scale problems in science, engineering, and commerce. For this c...

BACKGROUND Patient decision support tools have been developed as a means of providing accurate and accessible information in order for patients to make informed decisions about their care. Option Grids™ are a type of decision support tool specifically designed to be used during clinical encounters. OBJECTIVE To explore patients' views of the Option Grid encounter tool used in clinical consult...

Heterogeneity is often manifested in different forms even in environments that seem to be similar. In particular, clusters, grids, and infrastructure as a service (IaaS) clouds may appear straightforward to configure to be interchangeable. However, our experiences with mainstream parallel codes for solving complex computational fluid dynamics (CFD) problems demonstrate that secondary attributes...

Wind energy is increasing its participation as a main source of energy in power grids and electric utility systems around the world. One of the main difficulties of integrating large amounts of wind energy in power grids is the natural intermittency of its generated power [1, 2] due to the energy produced from the wind turbine being dependent on the availability of the wind, which is highly sto...

Several key economic scenarios involve agents having limited capacities whose types change with time, e.g., service workers attending to service requests, power plants supplying to power grids, and machines connected to computing grids. Dynamic mechanisms have been proposed to address the issue of dynamic types. Also, a few mechanisms have been proposed to account for limited capacities in stat...

Grids are distributed systems that dynamically coordinate a large number of heterogeneous resources to execute large scale projects involving collaborating teams of scientists, high performance computers, massive data stores, high bandwidth networking, and/or scientific instruments like telescopes, and synchrotrons. Failure in grids is arguably inevitable due to the massive scale and the hetero...

Higher-order finite element methods have emerged as an important discretization scheme for simulation. They are increasingly used in contemporary numerical solvers, generating a new class of data that must be analyzed by scientists and engineers. Currently available visualization tools for this type of data are either batch oriented or limited to certain cell types and polynomial degrees. Other...

Rotylenchulus reniformis was first detected in a single grid (100 m(2)) in May 2001 in a cotton field in Ashley County, AR, that was being utilized to evaluate the utility of grid-sampling for detection of Meloidogyne incognita. A total of 512 grids were sampled in the 6-ha field in the spring and fall for four years (2001 - 2004), nematode populations were determined for each grid, and nematod...

In recent years, Grid computing systems have emerged as a solution to achieve distributed systems. Grid System is a collection of computing resources and users that are scattered around the world. These systems are developing and becoming more widespread with ever-increasing speed. Development of Grids and increase of the number of available resources and also increase in the number of users’ r...
