Analysis of an arbitrary profile reflector antenna having resistivetype surfaceHpolarization case
(2008)A regularizationbased numerical solution is obtained for arbitraryshape conic section profile reflector antenna in 2D, for the Hpolarization case. New point is that the reflector surface is assumed a resistivetype ... 
Characteristic equations for the lasing Modes of infinite periodic chain of quantum wires
(2008)In this paper, we study the lasing modes of a periodic open optical resonator. The resonator is an infinite chain of active circular cylindrical quantum wires standing in tree space. Characteristic equations for the ... 
Distance laboratory applications ERRL: A study on radio communication in electronic field
(2008)In the last decade, the effect of internet usage in education is gradually increased. When we look from academic perspective, the new technologies provided alternatives for students learning. As distance education becomes ... 
Dynamics of commitment and contribution quality in collaborative communities
(2007)It is wellknown that commitment is an important ingredient for contributions of high quality. With the internet heading towards being an actionable social space, rather than a collection of websites, the issue of quality ... 
Elements of nanocrystal highfield carrier transport modeling
(Wiley  V C H Verlag GmbH & Co. KGaA, 2007)Embedded semiconductor nanocrystals (NCs) within wide bandgap oxide materials are being considered for light emission and solar cell applications. One of the fundamental issues is the highfield transport in NCs. This ... 
Generation of new frequencies in toroid microcavities
(2008)Microtoroid cavities with ultra high Qfactor have been fabricated using a combined process of photolithography and reflow technique for observing nonlinear effects such as generation of new frequency components. For this ... 
Laser action studies of φconjugated polymer microcavities
(2008)Unidirectional laser emission was observed from φconjugated polymer microcavities with spiral geometry, and from microdisks containing line defects. For both type of cavities directionality contrast of the laser emission ... 
Lexical cohesion based topic modeling for summarization
(Springer, 2008)In this paper, we attack the problem of forming extracts for text summarization. Forming extracts involves selecting the most representative and significant sentences from the text. Our method takes advantage of the lexical ... 
Mesoscopic Fano effect in an AharonovBohm interferometer Coulombcoupled to a nearby quantum dot
(2007)Motivated by the pionieering experiments of Buks et al. [Nature 391, 871 (1998)] we investigate the visibility of the Fano effect in a singledot AharonovBohm interferometer which is Coulombcoupled to a nearby quantum ... 
Motion control for realistic walking behavior using inverse kinematics
(2007)This study presents an interactive hierarchical motion control system for the animation of human figure locomotion. The articulated figure animation system creates movements using motion control techniques at different ... 
Numerical modeling of electromagnetic scattering by perfectly conducting surfaces of revolution
(2008)The integrodifferential equation (IDE) of a threedimensional (3D) electromagnetic excitation problem of unclosed surfaces is numerically treated by means of the novel direct solver. © 2008 IEEE. 
On the performance of linear leastsquares estimation in wireless positioning systems
(2008)A common technique for wireless positioning is to estimate timeofarrivals (TOAs) of signals traveling between a target node and a number of reference nodes, and then to determine the position of the target node based on ... 
An overview of research in 3DTV
(2007)3DTV is regarded by the experts and the general public as the next major step in video technologies. The ghostlike images of remote persons or objects are already depicted in many futuristic movies; both entertainment ... 
Performance analysis of turbo codes over Rician fading channels with impulsive noise
(2007)The statistical characteristics of impulsive noise differ greatly from those of Gaussian noise. Hence, the performance of conventional decoders, optimized for additive white Gaussian noise (AWGN) channels is not promising ... 
Raman and TEM studies of Ge nanocrystal formation in SiO x: Ge / SiOx multilayers
(2007)Alternating germanosilicatesiliconoxide layers of 1030 nm thickness were grown on Si substrates by plasma enhanced chemically vapor deposition (PECVD). The compositions of the grown films were determined by Xray ... 
Solution of extremely large integralequation problems
(2007)We report the solution of extremely large integralequation problems involving electromagnetic scattering from conducting bodies. By orchestrating diverse activities, such as the multilevel fast multipole algorithm, iterative ... 
Theoretical investigations on the energy relaxation in twodimensional GaN systems
(2007)We theoretically study the energy relaxation of hot electrons via LOphonon emission in twodimensional GaN systems. We employ a model in which electrons and the lattice are in equilibrium separately, and the effective ... 
Theoretical limits and a practical estimator for joint estimation of respiration and heartbeat rates using UWB impulse radio
(2007)In this paper, CramerRao lower bounds are derived fo r joint estimation of respiration and heartbeat rates via impulse radio ultrawideband signals. Generic models are employed for displacement functions due to respiration ...
