Due to the popularity of context-aware computingand the rapid growth of the smart phone devices, modeling anindividual's phone call response behavior may assist them intheir daily activities for managing call interruptions. A key stepof such modeling is to discovering call response behavioral rulesbased on multi-dimensional contexts related to individual'sbehavior. Currently, researchers use classification...
Autonomous Underwater Vehicle docking technology is now extensively used in the field of underwater. Vision guidance, as one of its core components, shows a great development prospect. In this paper, a brief description of the vision guidance models and the previous algorithm were described. Both the advantages and disadvantages of that algorithm would be analyzed. By using grey-scale feature analysis,...
There is an increasing demand for context-aware adaptive services that can evolve at runtime in response to unanticipated changes in their environments or functionalities. Enabling the runtime evolution of such context-aware adaptive services is still a major challenge. In this paper, we introduce a novel approach to tackle this challenge. At the development time, our approach explicitly models a...
NURBS curve and surface modeling technology is an emerging technology, developed in the 1980s, has been widely used in the CAID and CG. In CAID software based on NURBS technology, the quality of curve directly affects the quality of surface, and the post-editing and modification of the surface. This paper is based on the CAID software platform, combined the basic theory of NURBS curves with practical...
Simulation optimization is attracting increasing research interest from the modeling and simulation community. Although there is much research on how to apply various simulation optimization techniques to solve numerous practical and research problems, researchers find that existing optimization routines are difficult to extend or integrate and often require one to develop their own optimization methods...
Progress in programming paradigms and languages has over time influenced the way that simulation programs are written. Modern object-oriented, functional programming languages are expressive enough to define embedded Domain Specific Languages (DSLs). The Scala programming language is used to implement ScalaTion that supports several popular simulation modeling paradigms. As a case study, ScalaTion...
A systematic computational fluid dynamic (CFD) study was performed to investigate the effects of operating parameters of chamber pressure and wafer carrier rotation rate on the GaAs/AlGaAs deposition rate and uniformity in vertical rotating disc metal organic chemical vapor deposition (MOCVD) reactors. It is shown that significant improvement of the reactors efficiency can be achieved by finding the...
Cloud computing affects the development of mobile learning with its unique advantages. This article first sums up the traditional mode of mobile learning, analyses the characteristics of various patterns, sum up the characteristics of the cloud computing, and then make mobile learning mode under a cloud computing environment.
Business Process Execution Language (BPEL) provides the capability of assembling business processes, it is the important technical foundation used by SOA for portfolio of services and service choreography, and developing BPEL business processes needs the support of visual modeling tools. Existing modeling tools are inadequate in supporting automatic layout in a graphical interface. When developing...
Testing enterprise software that communicates with a large number of other software systems is a challenging task as it is often difficult to replicate the size and heterogeneity of large enterprise environments. In particular, it is challenging to conduct testing of non-functional properties related to scalability, performance, and robustness of enterprise software systems when deployed into such...
