A Plane Wave Equivalent Model for Forward Scatter Shadow Ratio in Spherical Wave and Its Application in Shadow Profile Retrieval

open access: yesIEEE Access, 2023
The forward scatter shadow ratio (FSSR), a novel parameter in forward scatter radar (FSR) systems, has been introduced recently for a plane wave. In contrast to conventional parameters like the forward scatter cross section (FSCS), FSSR utilizes the ...

Coherent states for a system of an electron moving in a plane [PDF]

open access: yesJournal of Physics Communications, 2021
Abstract In this paper, we construct the coherent states for a system of an electron moving in a plane under uniform external magnetic and electric fields. These coherent states are built in the context of both discrete and continuous spectra and satisfy the Gazeau-Klauder coherent state properties Gazeau and Klauder (1999 J. Phys.

Oh, wait, O8 de Sitter may be unstable!

open access: yesJournal of High Energy Physics, 2021
We analyze the stability of four-dimensional de Sitter vacua constructed by compactifying massive Type IIA supergravity in the presence of two O8 sources [1]. When embedded in String Theory the first source has a clear interpretation as an O8− plane, but

Mechanics of moving contacts involving functionally graded multiferroics

open access: yesArchives of Mechanics, 2023
This article introduces solution procedures for moving contacts involving functionally graded multiferroic coatings. A moving rigid punch of a flat or a triangular profile is assumed to be in contact with a multi-layer medium comprising magneto-electro ...

A kinetic triangulation scheme for moving points in the plane [PDF]

open access: yesComputational Geometry, 2010
We present a simple randomized scheme for triangulating a set $P$ of $n$ points in the plane, and construct a kinetic data structure which maintains the triangulation as the points of $P$ move continuously along piecewise algebraic trajectories of constant description complexity.

Moving averages in the plane

open access: yesIllinois Journal of Mathematics, 2012
Given a sequence of rectangles \(Q = \{ Q_1, Q_2, \ldots \}\) in the plane whose lower left corner is the origin, \textit{A. M. Stokolos} [Stud. Math. 88, No. 2, 103--120 (1988; Zbl 0706.28005)] introduced the maximal operator \[ M_{Q}f(x) = \sup_{i} \frac{1}{| Q_i |} \chi_{Q_i}* | f | (x).

Moving Target Detection Based on the Spreading Characteristics of SAR Interferograms in the Magnitude-Phase Plane

open access: yesRemote Sensing, 2015
We propose a constant false alarm rate (CFAR) algorithm for moving target detection in synthetic aperture radar (SAR) images based on the spreading characteristics of interferograms on the magnitude-phase (M-P) plane.

EPI-HYPOCYCLOIDS AND EPI-HYPOCYCLOIDAL CANAL SURFACES

open access: yesStructural Mechanics of Engineering Constructions and Buildings, 2018
In the article are regarded the curves - epiand hypocycloids, which are formed by the moving of the generating points, linked with the circles of the same radius and which are at the same time outside and inside of the unmoving circle. There is shown the

A Particle on a Moving Plane with Coulomb Friction [PDF]

open access: yesNelineinaya Dinamika, 2019
The purpose of this paper is the analytical study of some results of A. F. Filippov, which the author believes to be of crucial importance to gain insight into the dynamics of systems with Coulomb friction. The motion of a particle on a horizontal vibrating plane with Coulomb friction is investigated.
