There has been a growing interest in the cooperative communication of power line and wireless dual-medium, due to promising transmission quality immense flexibility network. However, under condition hybrid fading impulsive noise, theoretical analysis two-way relaying with is difficult because lack closed analytical expressions. In this study, authors propose signal processing method based on Lo...

The routing and wavelength assignment problem is one of the most important issues in optical transport networks based on the Wavelength Division Multiplexing (WDM) technique. In this paper, a novel approach using path conflict graphs and an algorithm for finding all edge disjoint paths is proposed. The performance of the proposed algorithm is compared with that of the bounded greedy approach fo...

We present a new approach for linking heterogeneous data of the same objective nature, such as 2D maps, 3D virtual environments and videos with GPS data. We have identified three key challenges (georeferencing, content creation for geospatial videos and bidirectional linking) that should be addressed to link among geographic hypermedia. We propose an easily implementable data model that serves ...

Over the past decade, rapid advances in web technologies, coupled with innovative models of spatial data collection and consumption, have generated a robust growth in geo-referenced information, resulting in spatial information overload. Increasing ‘geographic intelligence’ in traditional text-based information retrieval has become a prominent approach to respond to this issue and to fulfill us...

this paper explores the flexile flow lines where setup times are sequence- dependent. the optimization criterion is the minimization of total weighted completion time. we propose an iterated greedy algorithm (iga) to tackle the problem. an experimental evaluation is conducted to evaluate the proposed algorithm and, then, the obtained results of iga are compared against those of some other exist...

The need for integrating geospatial information (GI) data from various heterogeneous sources has seen increased importance for geographic information system (GIS) interoperability. Using domain ontologies to clarify and integrate the semantics of data is considered as a crucial step for successful semantic integration in the GI domain. Nevertheless, mechanisms are still needed to facilitate sem...

Wireless sensor networks are collections of large number of sensor nodes. The sensor nodes are featured with limited energy, computation and transmission power. Each node in the network coordinates with every other node in forwarding their packets to reach the destination. Since these nodes operate in a physically insecure environment; they are vulnerable to different types of attacks such as s...

The North Carolina Geospatial Data Archiving Project (NCGDAP) is a three-year joint effort of the North Carolina State University Libraries and the North Carolina Center for Geographic Information and Analysis focused on collection and preservation of digital geospatial data resources from state and local government agencies. NCGDAP is being undertaken in partnership with the Library of Congres...
