The patient authoring interface for each disease in the Maryland Virtual Patient simulation environment reveals the conceptual substrate of the disease model. Revealing the disease model to the community both explains how the interactive simulations work and invites collaboration from the wider community.

This paper presents a system for modeling lichens and simulating their propagation and growth in a virtual scene. Lichens colonize almost every substrate in nature and play an important role in the visual appearance of a natural object. The propagation of lichens over the substrate is performed by an Open Diffusion Limited Aggregation model constrained by the characteristics of the environment....

Many cloud computing technologies, such as MapReduce, use file systems as the system-wide substrate for data handling. A distributed file system provides a global name space and stores data persistently, but it also introduces significant overhead. Several recent systems use DRAM to store data and tremendously improve the performance of cloud computing systems. However, both our own experience ...

this study deals with the visibility, influence rate of diffrent links in virtual universities websites. the current community research is consisted of websites of 21 non medical universities websites and 8 websites of iran medical universities. the websites have been retrieved by the use of searchin and goolge webometic tools and are downloaded on personal computers to analyze their links. the...

Recent studies for network virtualization have shown a promising way to overcome the Internet ossification. The one of the key issues in network virtualization is a virtual network mapping problem, i.e., mapping a virtual network to the physical network. The situations of dynamic arrivals of virtual network request and the limited life cycle of the virtual networks pose significant challenges t...

Assigning virtual network resources to physical network components, called Virtual Network Embedding, is a major challenge in cloud computing platforms. In this paper, we propose a memetic elitist pareto evolutionary algorithm for virtual network embedding problem, which is called MEPE-VNE. MEPE-VNE applies a non-dominated sortingbased multi-objective evolutionary algorithm, called NSGA-II, to ...
