    This paper discusses about new approaches for protein function identification and ligand screening. To find a robust computational method it develops a ligand homology modeling approach and show that remotely related proteins identified by threading often share a common binding site occupied by chemically similar ligands.

    Molecular epidemiology of viral infections is based on identifying genetic markers to assist in epidemiological investigation. Early molecular technologies were limited in its capacity and were dominated by analytical methodology focusing on the viral agent itself where computational technologies were almost exclusively used for phylogenetic inference. Embracing the approaches and achievements of ... View full abstract»

    A large scale HLA-based simulation (federation) is composed of a large number of simulation components (federates), which may be developed by different participants and executed at different locations. These federates are subject to failures due to various reasons. What is worse, the risk of federation failure increases with the number of federates in the federation. In this paper, a fault toleran... View full abstract»

    Interest management provides scalable data distribution for large-scale distributed virtual environments by filtering irrelevant messages on the network. The interest matching process is essential for most of the interest management schemes which determines what data should be sent to the participants as well as what data should be filtered. Most of the existing interest matching approaches focus ... View full abstract»

    Maintaining interactivity is one of the key challenges in distributed virtual environments (DVE) due to the large, heterogeneous Internet latency and the fact that clients in a DVE are usually geographically separated. Previous work in this area have dealt with optimizing interactivity performance given limited server resource. In this paper, we consider a new problem, termed the performance-const...

    Predicting the time-performance of a Distributed Simulation (DS) system may be of interest to evaluate system alternatives during the development cycle, before the system is implemented. In this paper, we introduce a methodology to predict the execution time of a DS system during its design phase. The methodology is based on a model-building approach that, basing on the design documents of the DS ... View full abstract»

    In this paper we present the problem of optimizing a business process model with the objective of finding the most beneficial assignment of tasks to agents, without modifying the structure of the process itself. The task assignment problem for four types of processes are distinguished and algorithms for finding optimal solutions to them are presented: 1) a business process with a predetermined wor...

    An algorithm portfolio is a set of algorithms that are bundled together for increased overall performance. While being mostly applied to computationally hard problems so far, we investigate portfolio selection for simulation algorithms and focus on their application to adaptive simulation replication. Since the portfolio selection problem is itself hard to solve, we introduce a genetic algorithm t... View full abstract»

    Ad hoc distributed simulation is an approach to predict future states of operational systems. It is based on embedding on-line simulations into a sensor network and adding communication and synchronization among the simulators. While prior work focused on this approach in the context of online management of transportation systems, this paper describes a generalization of the method and shows how i... View full abstract»

    We propose a computing technique for efficient parallel simulation of compute-intensive DEVS models on the IBM Cell processor, combining multi-grained parallelism and various optimizations to speed up the event execution. Unlike most existing parallelization strategies, our approach explicitly exploits the massive fine-grained event-level parallelism inherent in the simulation process, while most ...

    A simulation model composed using reusable components is semantically valid if it produces meaningful results in terms of expressed behaviors and meets the desired objective. This paper focuses on the validation of component-based data-driven simulation. In data-driven simulation applications, it is necessary to model entity behavior at higher resolution. In simulations such as military training s... View full abstract»

    Digital hardware designs are nearly always tested and validated prior to deployment using functional-level simulation. Each component of the design, such as a four-bit adder or an eight-to-one multiplexer, is described and modeled as a set of inputs and a set of outputs that change based on changes in the input. Using traditional discrete event simulation, each change in the input set for a compon... View full abstract»

    Multi-core processors are commonly available now, but most traditional computer architectural simulators still use single-thread execution. In this paper we use parallel discrete event simulation (PDES) to speedup a cycle-accurate event-driven many-core processor simulator. Evaluation against the sequential version shows that the parallelized one achieves an average speedup of 10.9x (up to 13.6x) ... View full abstract»

    The spatial scale, runtime speed and behavioral detail of epidemic outbreak simulations together require the use of large-scale parallel processing. In this paper, an optimistic parallel discrete event execution of a reaction-diffusion simulation model of epidemic outbreaks is presented, with an implementation over the ¿sik simulator. Rollback support is achieved with the development of a novel r... View full abstract»

    Wireless network simulation is used for research because of its simplicity and repeatability. While simple radio propagation models are evaluated quickly and are suitable for simple scenarios, sophisticated models can handle more complex environments and provide better accuracy. However, the cost of higher accuracy is slower execution speed. This paper describes experiments that validate ray-traci... View full abstract»

    Ethernet is the most widely implemented low-level networking technology used today, with Gigabit Ethernet seen as the emerging standard implementation. The backbones of many large scale networks (e.g., data centers, metro-area deployments) are increasingly made up of Gigabit Ethernet as the underlying technology, and Ethernet is seeing increasing use in dynamic and failure-prone settings (e.g., wi...

    The expansion of the Internet routing system results in a number of research challenges, in particular, the Border Gateway Protocol (BGP) starts to show its limits a.o. in terms of the number of routing table entries it can dynamically process and control. Dynamic routing protocols showing better scaling properties are thus under investigation. However, because deploying under-development routing ... View full abstract»
