Effect of the Channel Estimation Error on the Performance of the Source Estimator in a Wireless Sensor Network with Orthogonal Channels
(IEEE, 2008)
In this work effect of the channel estimation error on the MSE performance of the source estimator in a wireless sensor network with orthogonal flat fading channels is studied. A two-phase approach was employed where in ...
Joint Data Detection and Channel Estimation for OFDM Systems in the Presence of Very High Mobility
(IEEE, 2009)
This paper is concerned with the challenging and timely problem of joint channel estimation and data detection for orthogonal frequency division multiplexing (OFDM) systems in the presence of frequency selective and very ...
On preserving connectivity of autonomous mobile robots
(IEEE, 2009)
The connectivity of the autonomous mobile robots is considered in this paper. The group navigation is provided using simple local steering rules and without any explicit communication. Sub-optimal solutions are invoked to ...
Biclustering Expression Data Based on Expanding Localized Substructures
(Springer-Verlag Berlin, 2009)
Biclustering gene expression data is the problem of extracting submatrices of genes and conditions exhibiting significant correlation across both the rows and the columns of a data matrix of expression values. We provide ...
Analytical Expense Management System
(IEEE, 2009)
Although the development of communication technologies (e.g: UMTS ADSL) allowed the elaboration of multiple users' web applications (e.g. information storage) there are still many improvements on many applications to be ...
Modeling the optical properties of WO(3) and WO(3)-SiO(2) thin films
(Elsevier Science Bv, 2008)
The optical properties and surface morphology of sol-gel spin coated WO(3) and WO(3)-SiO(2) composite films annealed at 250 and 400 degrees C are investigated. For the purpose of extracting the optical parameters of the ...
Electrochromic properties of heat-treated thin films of CeO2-TiO2-ZrO2 prepared by sol-gel route
(Elsevier Science Bv, 2008)
CeO2-TiO2-ZrO2 thin films were prepared using the sol-gel process and deposited on glass and ITO-coated glass substrates via dipcoating technique. The samples were heat treated between 100 and 500 degrees C. The heat ...

Fully Decentralized and Collaborative Multilateration Primitives for Uniquely Localizing WSNs
(Springer International Publishing Ag, 2010)
We provide primitives for uniquely localizing WSN nodes. The goal is to maximize the number of uniquely localized nodes assuming a fully decentralized model of computation. Each node constructs a cluster of its own and ...
FLEX: A Modular Software Architecture for Flight License Exam
(Springer-Verlag Berlin, 2010)
This paper is about the design and implementation of an examination system based on World Wide Web. It is called FLEX-Flight License Exam Software. We designed and implemented flexible and modular software architecture. ...
