he fuel-efficient diesel engine may face a bleak future unless engineers can dramatically reduce its particulate emissions to meet likely future regulations. Low-cost solutions may emerge if engineers can rethink engine and fuels technologies in tandem, tailoring the fuel properties to the engine design and vice versa. To help them achieve that match, Energy Laboratory researchers are formulati...

Phase transitions in polar binary mixtures can be drastically altered by even a small amount of salt. This is because the preferential solvation strongly depends on the ambient composition. Together with a summary of our research on this problem, we present some detailed results on the role of antagonistic salt composed of hydrophilic and hydrophobic ions. These ions tend to segregate at liquid...

Recently, more and more enterprises are embracing SOA paradigm to integrate and implement interoperable, robust and platform-independent distributed applications. Therefore, service discovery and composition become two main tasks which have gained great momentum. In order to improve the efficiency of service discovery and composition, a method is proposed in this paper. Firstly, some concepts a...

The hybridization of models of algorithmic composition models gave birth to Hybridized Interactive Algorithmic Composition (H.I.A.C.) model. This hybridized model was derived from the existing algorithmic composition models – where their strengths were harnessed and their weaknesses transparently subdued. The hybridized model was then analyzed using Unified Modeling Language (UML) as an Object-...

One of the most challenging issues of service–centric software engineering is the QoS–aware composition of services. The aim is to search for the optimal set of services that, composed to create a new service, result in the best QoS, under the user or service designer constraints. During service execution, re-planning such a composition may be needed whenever deviations from the QoS estimates o...

[Motivation] Web Services technology has emerged as a promising solution for creating distributed systems with the potential to overcome the limitation of former distributed system technologies. Web services provide a platform-independent framework that enables companies to run their business services over the internet. Therefore, many techniques and tools are being developed to create business...

1 Mixed traffic, characterized by diverse vehicles, changing composition, lack of lane discipline, etc. is best modeled 2 by micro simulation. However, the majority of the leading micro simulation packages and their calibration 3 methodologies have been developed considering less complex homogeneous traffic. Hence, a methodology for 4 calibrating a micro simulation model for mixed traffic is pr...

This paper proposes a new approach for paint appearance simulation. Coatings color and appearance change significantly according to lighting and observation conditions. The aim of this study is to propose both real time and accurate solutions for painted surface simulation. To solve real time constraints, we have chosen to simulate the paint appearance thanks to textures. Each texture represent...

Simulation models are abstract representations of systems one wants to study through computer simulation. In multiagent based simulation, such models usually represent agents and their relations. An important issue concerning these models is how they can be effectively reused across different simulations. But while much attention has been given to other engineering issues, model reuse has remai...
