A decentralized parallel one-pass fixed-interval deconvolution algorithm for multisensor systems with multiplicative noises     

Chu Dongsheng  Liu Bin  Liang Meng  Zhang Ling 《中国海洋大学学报(英文版)》2002,1(2):206-210

A decentralized parallel one-pass deconvolution algorithm for multisensor systems with multiplicative noises is proposed. Comparing with the conventional deconvolution algorithm, it avoids the computational overload and the high storage requirement. The algorithm is optimal in the sense of linear minimum-variance. The simulation results illustrate the validity of the proposed algorithm.  相似文献   

On the Chermnykh-Like Problems: II. The Equilibrium Points     

Li-Chin Yeh  Ing-Guey Jiang 《Astrophysics and Space Science》2006,306(4):189-200

Motivated by Papadakis (2005a, b), we study a Chermnykh-like problem, in which an additional gravitational potential from the belt is included. In addition to the usual five equilibrium points (three collinear and two triangular points), there are some new equilibrium points for this system. We studied the conditions for the existence of these new equilibrium points both analytically and numerically.  相似文献

Observational manifestations of the change in the tilt of the accretion disk to the orbital plane in her X-1/HZ her with phase of its 35-day period     

D. K. Klochkov  N. I. Shakura  K. A. Postnov  R. Staubert  J. Wilms  N. A. Ketsaris 《Astronomy Letters》2006,32(12):804-815

We analyze and interpret the RXTE/ASM X-ray light curves for the close binary system Her X-1/HZ Her obtained from February 1996 to September 2004. Some of the features found previously in the averaged X-ray light curves are confirmed by the new RXTE/ASM data. In particular, the anomalous dips and post-eclipse recoveries in two successive orbits in the short-on state are clearly distinguishable and are stable features of the X-ray light curves. We argue that to account for these features, the tilt of the accretion disk to the orbital plane must be assumed to change with phase of the 35-day period. We present a numerical model that can reproduce the observed features of the light curves.  相似文献

On Franck-Condon factors and intensity distributions in some band systems of I2, NS and PS molecules     

K. Raghuveer  L. N. A. Narasimham 《Journal of Astrophysics and Astronomy》1982,3(1):13-25

Potential curves for theB andX states of I₂, NS and PS have been obtained by Rydberg-Klein-Rees (RKR) method. From these RKR potentials, Franck-Condon factors (FCFs) lot the above band systems have been calculated using the best available molecular constants, tested for accuracy on the electronic transition moment (ETM)-r-centroid curve in the case of I₂ and used in the study of observed abnormal intensity distribution in some bands of NS. A brief outline of the method used in the calculations of the FCFs is given.  相似文献   

First locking of the Virgo central area interferometer with suspension hierarchical control     

《Astroparticle Physics》2004,20(6):629-640

Operation of the central portion of Virgo as a simple 6 m Michelson interferometer has given the first demonstration of the possibility to control an interferometer suspended from Virgo full scale multistage seismic attenuators using information derived from the interferometer locking signal. A special role in the control is played by the first stage of these suspensions, an inverted pendulum: besides its seismic preisolation action, this stage has positioning dynamics of several mm, and it allows to exert a very low frequency control at the upper level of the suspension using the interferometer fringe signal. The application of this feedback to the top-stage of the suspension allows corrections of drifts, such as tidal ones, at a stage of the suspension where a large dynamic range in displacements is available, without introducing noise at the level of the mirror, resulting in a significant reduction of the lock keeping force applied directly on the mirror at the lowest stage of the attenuator.  相似文献
