Wireless sensor networks (WSNs) are considered as energy constrained network because it contains sensor nodes with limited battery capacity and transmission range. In WSNs there is one mechanism used to enlarge the lifespan of network and provide more efficient functioning procedures that is clustering. Clustering is a process to subdivide the sensing field of sensor […]
Class-dependent density-based feature Elimination
High-dimensional data sets are inherently sparse and hence, can be transformed to lower dimensions without losing too much information about the classes. In this paper we propose a new feature ranking algorithm, termed as, class-dependent density-based feature elimination, for binary data sets. CDFE uses a measure termed as, diff-criterion, to estimate the relevance of features. […]
Citation Parser using Sequent Alignment
Parsing citations is essential for integrating bibliographical information published on the Internet. Most citation management techniques are based on the assumption that we can correctly identify the main components of a citation, such as authors’ names, title, publication venue, date, and the number of pages. In this paper, we propose a sequence-alignment based citation parser, […]
Detecting and Tracking Vehicle in Aerial Surveillance
In this paper we present automatic vehicle detection and tracking system for aerial surveillance. In the existing frameworks they apply either region based or sliding window based of vehicle detection in aerial surveillance. These method have highly depends on the color segmentation, a lot of miss detections on rotated vehicles and high computational complexity. So […]
Logoot-Undo: Distributed Collaborative Editing System on P2P Networks
Peer-to-peer systems provide scalable content distribution for cheap and resist to censorship attempts. However, P2P networks mainly distribute immutable content and provide poor support for highly dynamic content such as produced by collaborative systems. A new class of algorithms called CRDT (Commutative Replicated Data Type), which ensures consistency of highly dynamic content on P2P networks, […]
An Autonomous Engine for Services Configuration and Deployment
The runtime management of the infrastructure providing service-based systems is a complex task, up to the point where manual operation struggles to be cost effective. As the functionality is provided by a set of dynamically composed distributed services, in order to achieve a management objective multiple operations have to be applied over the distributed elements […]
Labeling Dynamic XML Documents: An Order-Centric Approach
Dynamic XML labeling schemes have important applications in XML Database Management Systems. In this paper, we explore dynamic XML labeling schemes from a novel order-centric perspective. We compare the various labeling schemes proposed in the literature with a special focus on their orders of labels. We show that the order of labels fundamentally impacts the […]
