Network virtualization opens a promising way to support diverse applications over a shared substrate by running multiple virtual networks. Current virtual data centers in cloud computing have flexible mechanisms to partition compute resources but provide little control over how tenants share the network. This paper proposes a utility-maximization model for bandwidth sharing between virtual netw...

As social and economic forces impact business practices, the significance of delivering effective employer-driven, employment services (i.e., demand-side model) to facilitate employment and retention for individuals who have not traditionally benefited from labor force participation is of increased importance. The purpose of this paper is to provide descriptions of two public-private partnershi...

BACKGROUND Research activities in sub-Saharan Africa may be limited to delegated tasks due to the strong control from Western collaborators, which could lead to scientific production of little value in terms of its impact on social and economic innovation in less developed areas. However, the current contexts of international biomedical research including the development of public-private partn...

An approach to assessing the content trust of information resources based on a publishing criterion has been developed and applied to several tens of spectroscopic expert datasets. The results represented as an OWL-ontology are shown to be accessible to programmable agents. The assessments enable the amount of measured and calculated trusted and distrusted data for spectroscopic quantities and ...

Cloud computing places an organization’s sensitive data in the control of a third party, introducing a significant level of risk on the privacy and security of the data. We propose a new management and security model for cloud computing called the Private Virtual Infrastructure (PVI) that shares the responsibility of security in cloud computing between the service provider and client, decreasin...

Today, we’ll discuss an aspect of networking that has risen in prominence over the last decade or so: datacenters. Datacenters are large private networks consisting of tens of thousands of servers [15, 16]. Some of these datacenters are in buildings that are the size of six football fields [3]. We’ll first discuss how such datacenters came to be [8]. We’ll then discuss in some detail one specif...

As businesses are increasingly relying on the cloud to host their services, cloud providers are striving to offer guaranteed and highlyavailable resources. To achieve this goal, recent proposals have advocated to offer both computing and networking resources in the form of Virtual Data Centers (VDCs). Subsequently, several attempts have been made to improve the availability of VDCs through reli...

Cognitive rehabilitation is an empirically based field driven y multiple sources of activities and knowledge bases. Drawng on frames of reference provided by rehabilitation, neurosychology, and rehabilitation psychology, cognitive rehabiliation has evolved to a point where studies have been generated o qualify for consideration in tables of evidence. At the center f cognitive rehabilitation is ...

The level of interest in aural rehabilitation has increased recently, both in clinical use and in research presentations and publications. Advances in aural rehabilitation have seen previous techniques such as speech tracking and analytic auditory training reappear in computerized forms. These new delivery methods allow for a consistent, cost-effective, and convenient training program. Several ...

Mean CDE (cumulative dissipated energy) values were compared for an open hospital- based surgical center and a free-standing surgical center. The same model of phacoemulsifier (Alcon Infiniti Ozil) was used. Mean CDE values showed that surgeons (individual private practice) at the free-standing surgical center were more efficient than surgeons (individual private practice) at the open hospital-...
