Near optimal wireless data broadcasting based on an unsupervised neural network learning algorithm
(2001)Wireless Data Broadcasting (WDB) is proven to be an efficient information delivery mechanism of nearly unlimited scalability. However, successful performance of a WDB based system is not always guaranteed - it strongly ...

Necessary conditions for partially observed diffusions
(IEEE, 1993)We present a new approach to deriving necessary conditions for stochastic partially observed control problems when the control enters the drift coefficient, and correlation between signal and observation noise is allowed. ...

Necessary conditions of optimization for partially observed controlled diffusions
(1999)Necessary conditions are derived for stochastic partially observed control problems when the control enters the drift coefficient and correlation between signal and observation noise is allowed. The problem is formulated ...

Negative-refractive-index transmission-line metamaterial-loaded dipole antennas
(2012)Several compact, fully-printed negative-refractive-index transmission-line (NRI-TL) metamaterial-loaded dipole antennas are proposed. The antennas achieve multi-band behaviour by loading a host dipole antenna with series ...

Negative-refractive-index transmission-line metamaterials and enabling electromagnetic applications
(2004)The negative-refractive-index (NRI) metamaterials, for which the permittivity and permeability are simultaneously negative, were discussed. The results for two RF/Microwave devices and structures, based on transmission-line ...

Negotiating the right of return
(2009)Negotiating the right of return is a central issue in post-conflict societies aiming to resolve tensions between human rights issues and security concerns. Peace proposals often fail to carefully balance these tensions or ...

Neighboring Optimal Guidance for Aeroassisted Orbital Transfer
(1993)A neighboring optimal guidance scheme for a nonlinear dynamic system is devised with stochastic inputs and perfect measurements as applicable to fuel optimal control of an aeroassisted orbital transfer vehicle. For the ...

Network Coding for Security Against Eavesdropping Attacks in Elastic Optical Networks
(Springer International Publishing, 2020)In this work, routing and spectrum allocation (RSA) algorithms together with network coding (NC) are proposed for elastic optical networks. NC has been used in optical networks for protection against link failures and also ...
