A Robust Localization Framework to Handle Noisy Measurements in Wireless Sensor Networks
(IEEE, 2009)
We construct a robust localization framework to handle noisy measurements in wireless sensor networks. Traditionally many approaches employ the distance information gathered from ranging devices of the sensor nodes to ...
A Simple Iterative Equalizer for Space Time Coded Multiple Antenna Systems
(IEEE, 2009)
In this paperg a simple low complexity iterative receiver for spacetime coded zSTCg transmission is proposed and the pen formance over frequencyyselective fast and quasistatic fading channels is investigatedF Simulation ...
Cascaded Lossless Commensurate Line Synthesis
(IEEE, 2009)
In this paper a synthesis algorithm for cascaded lossless commensurate lines is summarized. The algorithm is based on transfer matrix factorization. Firstly the characteristic impedance of the extracted element is calculated ...
Polymer-Ceramic Nanocomposites
(Spie-Int Soc Optical Engineering, 2009)
Steady state fluorescence (SSF) and photon transmission (PT) techniques were used for studying film formation from TiO2 and Al2O3 covered polystyrene (PS) latex particles. These films were annealed at elevated temperatures ...
Towards Faster Branch Outage Simulations Using Simulated Annealing and Parallel Programming
(IEEE, 2009)
Contingency studies such as branch outage and generator outage are among important studies of energy management centers operations. Branch outage modeling on the other hand is one of the basic steps of post-outage state ...
Scaling Laws For Distributed Estimation Over Orthogonal Fading Channels
(IEEE, 2009)
We analyze the outage for distributed estimation over orthogonal fading channels as a function of the number of sensors K. We consider a scenario of fixed power per-sensor with an asymptotically large number of sensors. ...
Optimization Model for Distributed Routing for Disaster Area Logistics
(IEEE, 2009)
The problem of transportation in a disaster area can be seen broadly as having two aspects: (a) moving people and materials out of an area and (b) moving people and materiel into the same area. The common thread here is ...
Fluorescence technique for monitoring swelling of PAAm-kappa-carrageenan gel composites
(Shaker Publishing, 2009)
Steady-state fluorescence (SSF) technique was employed for studying swelling of polyacrylamide (PAAm) gels with various content of kappa- carrageenan. Disc shaped composite gels were prepared by free-radical cross/inking ...
Iterative Receiver for DS-CDMA Systems in the Presence of Time-Varying Channels
(IEEE, 2008)
In this paper we present an efficient iterative receiver structure of tractable complexity for joint multiuser detection and multichannel estimation (JDE) of direct-sequence code-division multiple-access systems operating ...
Navigation of autonomous mobile robots in connected groups
(IEEE, 2008)
The navigation of autonomous mobile robots as a group is considered in this paper. Definitions adopted from the graph theory are given to characterize the robot group. A local steering strategy is proposed such that when ...
