The growth in the popularity of Internet services, increasing of mobile users together with a wide range of access and mobile-networked devices, demands and inter-working of these heterogeneous access . Sometimes referred to as 4th generation (4G) , the overall objective is to provide a managed Always Connected (ABC) service over underlying heterogonous and mobile platforms while maintaining negotiated and Quality of Service (QoS) in an open and nonproprietary . paper proposes a new model and its architecture which is upon Policy-based Management (PBM) and provides a for the centralised management of networks based on level policies. However, it extends the basic PBM ideas provide a "layered approach" which facilitates the negotiation management services over interconnected heterogonous platforms thus achieving an always best connected . Finally this paper describes a proof-of-concept testbed demonstrates the implementation of this model in practice. Copyright 2008 ACM.
We present a reasoning procedure for ontologies with uncertainty described in Description Logic (DL) which include General TBoxes, i.e., include cycles and General Concept Inclusions (GCIs). For this, we consider the ...

Rank order correlation has been used extensively when the data is non-parametric or when the relationship between two variables is nonlinear and monotonic. In such cases, linear correlation measures, such as the product-moment coefficient, are inadequate and fail to detect correlative relations. We present a polyhedral indexing technique for rank order correlation queries for time series data. We use an interesting geometry interpretation of rank order correlation which lends itself to indexing by spatial indexes such as R-trees. Our experimental results indicate one to two orders of magnitudes improvement over sequential scan - the only alternative solution.

We investigated that the brightness magnitude of the Del Cephei had been adapted to three different training values and each training had four different hidden layers in the back-propagation neural network (BPANN) models. The best forecasting mean through different approaches in the BPANN model was obtained at 15% training with four hidden layers. However, the difference in forecasting accuracies of the different levels was not statistically significant.

In order to evaluate the structural complexity of class diagrams systematically and deeply, a new guiding framework of structural complexity is presented. An index system of structural complexity for class diagrams is given. This article discusses the formal description of class diagrams, and presents the method of formally structural complexity metrics for class diagrams from associations, dependencies, aggregations, generalizations and so on. An applicable example proves the feasibility of the presented method.

In the realm of substation automation (SA), communication infrastructure plays a vital role in mediating between physical and virtual worlds of substation. Specification of data exchanges through standardized communication stacks is therefore an important issue for all substation equipment manufacturers seeking to provide vendor interoperability. Nowadays competitive electric utility marketplace, reliable and real-time information become the key factor for reliable delivery of power to the endusers, profitability of the electric utility and customer satisfaction. The operational and commercial demands of electric utilities require a high-performance data communication network that supports both existing functionalities and future operational requirements. As communication arena is changing day by day, the need for efficient and reliable communication infrastructure to address SA is evident. In this respect, a communication network constitutes the core of the SA, thus the design of cost-effective and reliable network architecture is a crucial task. Most of the existing communication networks claim to address the need of communication architecture for SA but in some regard these claims just could not fulfill the constraints imposed by highly available environment for SA. This paper presents a survey and analysis of the current state-of-the-art communication infrastructure in the SA. As Ethernet technology becomes more reliable and also widely available with fiber optical communication so this paper also examines the key issues and requirements for Ethernet in the substation environment and also opens some research challenges.

In distributed and high performance applications it it is necessary to discover the aggregate resource capabilities of the collaborating peers. Another requirement of these applications is to locate the resources meeting the given aggregate search criteria. In this paper we present an unstructured peer-to-peer approach to aggregate node selection for resource management. Our objective is to efficiently calculate the aggregate value and search the aggregate node whose attribute matches or falls in the proximity of this value. Our contribution also includes the inclusion of an explicit network for aggregate query routing. We evaluated our protocol for accuracy, efficiency and communication cost through detailed simulations. Copyright 2008 ACM.
