This paper summarizes recent research on networked virtual computing in the NICL lab at Duke. Over the past few years, we have constructed a service-oriented substrate for networked sharing and adaptive middleware environments based on a virtual on-demand computing. The goal of the project is to develop protocols and tools that can link together virtual computing clusters at different sites, an...

The aim of this paper is to study the effect of substrate on the Cu3N thin films. At first Cu3N thin films are prepared using DC magnetron sputtering system. Then structural properties, surface roughness, and electrical resistance are studied using X-ray diffraction (XRD), the atomic force microscope (AFM) and four-point probe techniques respectively. Finally, the results are investigated and c...

This paper presents an agent-based platform to support the development of a management system for the network architecture proposed by the Horizon Project. The platform consists of a substrate network, software for creating virtual networks and a set of agents that support ontology to enable the development of a knowledge plan. We also show the prototype built to evaluate a simple ontology for ...

Maryland Virtual Patient (MVP) is a simulation and tutoring system for training medical personnel in cognitive decision making skills. It is implemented as an agent network using an ontological knowledge substrate. This paper focuses on disease interaction in the MVP environment, including how diseases and/or their treatments can automatically give rise to other diseases, and how disease manife...

Distributed Feature Composition (DFC) is a new technology for feature specification and composition, based on a virtual architecture offering benefits analogous to those of a pipe-and-filter architecture. In the DFC architecture, customer calls are processed by dynamically assembled configurations of filter-like components: each component implements an applicable feature, and communicates with ...

Leveraging the traditional virtual network concept, some recent research works have proposed the Virtual Data Center (VDC) as an abstraction to capture both bandwidth and compute/storage resource requirements for an application. However a virtual node in a VDC is limited to a virtual machine (VM), which can only be embedded onto a single physical machine. This condition limits the applicability...
