We discuss fluctuation relations in simple cases of non-equilibrium Langevin dynamics. In particular, we show that close to non-equilibrium steady states with non-vanishing probability currents some of these relations reduce to a modified version of the fluctuation-dissipation theorem. The latter may be interpreted as the equilibrium-like relation in the reference frame moving with the mean loc...

In an isotropic, homogeneous, nondissipative, dielectric–magnetic medium that is simply moving with respect to an inertial reference frame, planewave solutions of the Maxwell curl postulates can be such that the phase velocity and the time–averaged Poynting vector are mutually orthogonal. Orthogonal–phase–velocity propagation thus adds to the conventional positive–phase–velocity propagation and...

We introduce a novel adaptive digital beamforming algorithm for application in cellular CDMA communications systems. A Noniterative Rank-one Signal Subspace eigenstruc-ture Update (NR1SSU) algorithm enables low-complexity re-cursive processing of beamforming weights. A PN chip-level IS-95 CDMA reference model 3] has been used to test the beamforming algorithm via simulation. Our results show th...

In today’s world ensuring security for important location is a burning issue. Surveillance system is playing an important role in the field of security. Moving object detection has been widely used in video surveillance system. This paper proposes a simple and efficient approach for real time moving object extraction in video sequences where moving object region is extracted from the moving edg...

A new modification of the dynamic multileaf collimator (dMLC) delivery technique for intensity-modulated therapy (IMRT) is outlined. This technique enables the tracking of a target moving through rigid-body translations in a 2D trajectory in the beam's eye view. The accuracy of the delivery versus that of deliveries with no tracking and of 1D tracking techniques is quantified with clinically de...

We construct a set of reference frames for description of the orbital and rotational motion of the Moon. We use a scalar-tensor theory of gravity depending on two parameters of the parametrized post-Newtonian (PPN) formalism and utilize the concepts of the relativistic resolutions on reference frames adopted by the International Astronomical Union in 2000. We assume that the solar system is iso...

Moving Object Detection is one of the key research areas of Image processing. In this regard many researches are underway to provide a novel approach to detect moving object with less space and time complexity. This paper, outlines the novel approach to detect high speed moving object with frame interleaving in frame differencing operation and clustering based compression for frame and backgrou...

Ostrovsky’s equation with time- and space-dependent forcing is studied. This model for long waves in a rotating fluid non-constant depth (topography). A classification of Lie point symmetries low-order conservation laws presented. Generalized travelling wave solutions are obtained through symmetry reduction. These exhibit profile that stationary moving reference frame whose speed can be constan...
