Animation of deformable models
(Pergamon Press, 1994)Although kinematic modelling methods are adequate for describing the shapes of static objects, they are insufficient when it comes to producing realistic animation. Physically based modelling remedies this problem by ... -
Closed-form green's function representations for mutual coupling calculations between apertures on a perfect electric conductor circular cylinder covered with dielectric layers
(IEEE, 2011-06-07)Closed-form Green's function (CFGF) representations are developed for tangential magnetic current sources to calculate the mutual coupling between apertures on perfectly conducting circular cylinders covered with dielectric ... -
Comment on "modeling the electrical conduction in DNA nanowires: Charge transfer and lattice fluctuation theories"
(American Physical Society, 2016)In a recent paper [S. Behnia and S. Fathizadeh, Phys. Rev. E 91, 022719 (2015)10.1103/PhysRevE.91.022719] an analytical approach is proposed for the investigation of the conductivity properties of DNA. The authors use mean ... -
Communication scheme by using synchronized chaotic systems
(IEEE, Piscataway, NJ, United States, 1996)A method to synchronize systems with chaotic behavior, in a master-slave configuration adapted to communication systems, is discussed. This work is motivated by the need for secure communication. In this method, the ... -
Comparative evaluation of absorbing boundary conditions using green's functions for layered media
(IEEE (Institute of Electrical and Electronics Engineers), 1995-06)Absorbing boundary conditions are comparatively studied using the Green's functions of the vector and scalar potentials for multilayer geometries and general sources. The absorbing boundaries are introduced as additional ... -
Comparative evaluation of absorbing boundary conditions using Green's functions for layered media
(Institute of Electrical and Electronics Engineers, 1996-02)Absorbing boundary conditions are comparatively studied using the Green's functions of the vector and scalar potentials for multilayer geometries and general sources. Since the absorbing boundaries are introduced as ... -
Dynamic boundary control of the timoshenko beam
(Pergamon Press, 1992)We consider a clamped-free Timoshenko beam. To stabilize the beam vibrations, we propose a dynamic boundary control law applied at the free end of the beam. We prove that with the proposed control law, the beam vibrations ... -
Electrostatic interactions in charged nanoslits within an explicit solvent theory
(Institute of Physics Publishing, 2015)Within a dipolar Poisson-Boltzmann theory including electrostatic correlations, we consider the effect of explicit solvent structure on solvent and ion partition confined to charged nanopores. We develop a relaxation scheme ... -
Fast and accurate analysis of complicated metamaterial structures using a low-frequency multilevel fast multipole algorithm
(2009)We present efficient solutions of electromagnetics problems involving realistic metamaterial structures using a low-frequency multilevel fast multipole algorithm (LF-MLFMA). Ordinary implementations of MLFMA based on the ... -
Fluctuation-dissipation and energy properties of a finite bath
(American Physical Society, 2016)This paper expands a recent proposal by the authors to rederive the Langevin equation for a test particle in a finite-size thermal bath using a perturbation approach that yields a cascade of Langevin-type equations. Such ... -
Integral equation anlaysis of an arbitrary-profile and varying-resistivity cylindrical reflector illuminated by an E-polarized complex-source-point beam
(Optical Society of America, 2009-06-09)A two-dimensional reflector with resistive-type boundary conditions and varying resistivity is considered. The incident wave is a beam emitted by a complex-source-point feed simulating an aperture source. The problem ... -
Integral equation based method for the fast analysis of irregularly contoured large finite phased arrays
(2007)A fast and accurate integral equation based hybrid method that can investigate electrically large, arbitrarily contoured finite planar arrays of printed elements is developed. The method is a hybridization of the Galerkin ... -
Integrated asymmetric vertical coupler pressure sensors
(2004)Design and analysis of a novel pressure sensor based on a silicon-on-insulator asymmetric integrated vertical coupler is presented. The coupler is composed of a single mode low index waveguide and a thin silicon slab. ... -
Markov modulated periodic arrival process offered to an ATM multiplexer
(Elsevier BV * North-Holland, 1995-04)When a superposition of on/off sources is offered to a deterministic server, we are faced with a particular queueing system, the analysis of which has a significant role in ATM networks. Periodic cell generation during ... -
Markov modulated periodic arrival process offered to an ATM multiplexer
(Publ by IEEE, Piscataway, NJ, United States, 1993)When a superposition of on/off sources is offered to a deterministic server, a particular queueing system arises whose analysis has a significant role in ATM based networks. Periodic cell generation during active times is ... -
A novel technique for a linear system of equations applied to channel equalization
(2009)In many inverse problems of signal processing the problem reduces to a linear system of equations. Accurate and robust estimation of the solution with errors in both measurement vector and coefficient matrix is a challenging ... -

Numerical simulation of optically trapped particles
(SPIE, 2014)Some randomness is present in most phenomena, ranging from biomolecules and nanodevices to financial markets and human organizations. However, it is not easy to gain an intuitive understanding of such stochastic phenomena, ... -
On Switching H ∞ Controllers for a Class of LPV Systems
(Institute of Electrical and Electronics Engineers, 2003)We consider switching H ∞ controllers for a class of LPV systems scheduled along a measurable parameter trajectory. The candidate controllers are selected from a given controller set according to the switching rules based ... -
On the design of AQM supporting TCP flows using robust control theory
(Institute of Electrical and Electronics Engineers, 2003)Recently it has been shown that the AQM (Active Queue Management) schemes implemented in the routers of communication networks supporting TCP (Transmission Control Protocol) flows can be modeled as a feedback control system. ...
