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 ... 
Closedform green's function representations for mutual coupling calculations between apertures on a perfect electric conductor circular cylinder covered with dielectric layers
(IEEE, 20110607)Closedform 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 masterslave 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
(Institute of Electrical and Electronics Engineers, 199602)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 ... 
Comparative evaluation of absorbing boundary conditions using green's functions for layered media
(IEEE (Institute of Electrical and Electronics Engineers), 199506)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 ... 
Dynamic boundary control of the timoshenko beam
(Pergamon Press, 1992)We consider a clampedfree 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 PoissonBoltzmann 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 lowfrequency multilevel fast multipole algorithm
(2009)We present efficient solutions of electromagnetics problems involving realistic metamaterial structures using a lowfrequency multilevel fast multipole algorithm (LFMLFMA). Ordinary implementations of MLFMA based on the ... 
Fluctuationdissipation 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 finitesize thermal bath using a perturbation approach that yields a cascade of Langevintype equations. Such ... 
Integral equation anlaysis of an arbitraryprofile and varyingresistivity cylindrical reflector illuminated by an Epolarized complexsourcepoint beam
(Optical Society of America, 20090609)A twodimensional reflector with resistivetype boundary conditions and varying resistivity is considered. The incident wave is a beam emitted by a complexsourcepoint feed simulating an aperture source. The problem ... 
Integral equation based method for the fast analysis of irregularly contoured large finite phased arrays
