771. Self-Deployment Algorithms for Coverage Problem in a Network of Mobile Sensors with Unidentical Sensing Range
Topic: Information Technology
Published: 12/6/2009
Authors: Vladimir V Marbukh, Kamran Sayrafian, Hamid Mahboubi, Kaveh Moezzi, Amir G. Aghdam
Abstract: In this paper, efficient sensor deployment algorithms are proposed to improve the coverage area in the target field. The proposed algorithms calculate the position of the sensors iteratively based on the existing coverage holes in the target field. T ...

772. Sensor Location through Linear Programming with Arrival Angle Constraints
Topic: Information Technology
Published: 3/14/2007
Authors: Camillo A Gentile, J Shiu
Abstract: In previous work, we established a linear programming framework to determine sensor location from measured link distances between neighboring nodes in a network. Besides providing greater accuracy compared to other techniques, linear programs in part ...

773. Sequential Time-Bin Entanglement Generation Using Periodically Poled KTP Waveguide
Topic: Information Technology
Published: 1/7/2009
Authors: Lijun Ma, Oliver T Slattery, Xiao Tang, Tiejun Chang
Abstract: We demonstrated non-degenerate sequential time-bin entanglement using periodically poled KTP waveguide at a repetition rate of 1 GHz. The wavelengths of signal and idler are 895 and 1310 nm. The two-photon-interference-fringe visibility is 79%.

774. Service Model Driven Variations in Security Measures for Cloud Environments
Topic: Information Technology
Published: 11/6/2011
Author: Ramaswamy Chandramouli
Abstract: With the increasing adoption of cloud computing service models - Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS), proper implementation of adequate and appropriate security protection measures has bec ...

775. Sharing Information Via the Internet - An Infoserver Case Study
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5757
Topic: Information Technology
Published: 11/1/1995
Author: Robert H Bagwill

776. Signal Processing Techniques for Smart Grid: Scanning the Issue
Topic: Information Technology
Published: 9/2/2012
Author: Hamid Gharavi
Abstract: This is an editorial article for a special issue on Smart Grid. The main emphasis of this issue is the technical challenges of the Smart Grid from a signal processing perspective. Therefore, the selected articles aim at articulating signal processing ...

777. Simplified Analysis of Matcher Performance and Fusion
Topic: Information Technology
Published: 10/14/2009
Author: Vladimir N Dvornychenko
Abstract: Provides some first-order techniques for analyzing matcher performance. A novel argument is used to derive the power-law as a kind of baseline for analyzing matcher performance. The power-law is then applied to two situations: a) CMC curves, and b) f ...

778. Simulation Model for the IEEE 802.15.3/3b WPAN Standard
Topic: Information Technology
Published: 9/15/2010
Author: Kamran Sayrafian
Abstract: The1IEEE 802.15.3 is an emerging technology for high data rate wireless multimedia applications in Wireless Personal Area Networks (WPAN). In this paper, a discrete event simulation model has been implemented using OPNET2 Modeler to simulate the esse ...

779. Simulation-based Approaches to Studying Effectiveness of Moving-Target Network Defense
Topic: Information Technology
Published: 6/11/2012
Authors: Riu Zhuang, Su Zhang, Scott DeLoach, Xinming Ou, Anoop Singhal
Abstract: Moving-target defense has been hypothesized as a potential game changer in cyber defense, including that for computer networks. However there has been little work to study how much proactively changing a network's configuration can increase the diffi ...

780. Slap Fingerprint Segmentation Evaluation II - Procedures and Results
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7553
Topic: Information Technology
Published: 1/12/2009
Author: Craig I Watson
Abstract: In 2004, NIST conducted a fingerprint slap segmentation study [1] to assess the state-of-the-art in fingerprint segmentation technology. Given the development of new technology it has become necessary to reassess the current state-of-the-art of segm ...
