Improving UXO discrimination using magnetic quadrupole moments
Currently there are no UXO discrimination techniques based on total-field magnetic sensor data that rely on multipole expansion parameters of higher order than the dipole. In some cases, however, it can be advantages to describe a UXO target with both dipole and quadrupole parameters. In this paper, we examine the properties of the quadrupole moment and illustrate them using a synthetic example...
متن کاملDipole and Quadrupole Moments in Image Processing
This paper proposes an algorithm for image processing, obtained by adapting to image maps the definitions of two well-known physical quantities. These quantities are the dipole and quadrupole moments of a charge distribution. We will see how it is possible to define dipole and quadrupole moments for the gray-tone maps and apply them in the development of algorithms for edge detection. 1. Introd...
متن کاملQuadrupole moments of sd-shell nuclei.
Shell-model calculations are presented for electric quadrupole moments of A =17—39 nuclei. The shell-model wave functions, which span the complete Ods/2-1sl/2 Dd3/2 model space in all instances, are obtained by diagonalizing an sd-shell Hamiltonian which consists of a fixed singleparticle energy spectrum and a single set of two-body matrix elements scaled as a function of the mass number A. Res...
متن کاملAperture Multipole Moments from Weak
The projected mass of a gravitational lens inside (circular) apertures can be derived from the measured shear inside an annulus which is caused by the tidal eld of the deeecting mass distribution. Here we show that also the multipoles of the two-dimensional mass distribution can be derived from the shear in annuli. We derive several expressions for these mass multipole moments in terms of the s...
متن کاملDirect measurement of STEP test mass quadrupole moments
A cryogenic torsion balance method is suggested to measure the residual quadrupole moments of the STEP test masses directly. The individual masses are placed on a torsion balance and the torque exerted by a rotating set of source masses is analysed. Conservatively, assuming a torque sensitivity of 10−13 N m, it appears that a quadrupole moment of 10−7 kg m2 can be detected. PACS number: 04.80.−q
