Analytical calculation of permanent magnet couplings

IEEE Transactions on Magnetics, 1993
An analytical method adapted to calculating the forces between permanent magnets is developed, and applied to the torque calculation of synchronous couplings. The method is based on the forces exerted between two elementary barshaped magnets. The curvature effect is taken into account by a corrective coefficient, and the yokes by magnetic images.

Analytical SER Calculation of Spatial Modulation

2008 IEEE 10th International Symposium on Spread Spectrum Techniques and Applications, 2008
Spatial modulation (SM) is a multiple antenna trans- mission approach that exploits the location of the transmitting antenna for conveying data information. In SM, only a single transmit antenna transmits at a time while all other antennas remain silent.

Analytical calculation of two-dimensional spectra

Optics Letters, 2015
We demonstrate an analytical calculation of two-dimensional (2D) coherent spectra of electronic or vibrational resonances. Starting with the solution to the optical Bloch equations for a two-level system in the 2D time domain, we show that a fully analytical 2D Fourier transform can be performed if the projection-slice and Fourier-shift theorems of ...

Analytical Calculation Methods

2010
Although numerical calculation methods for solving Laplace’s equation have developed remarkably in the past few decades, analytical methods still have significance in obtaining precise values and in easily evaluating parameter dependence, for example.

Analytical molecular surface calculation

Journal of Applied Crystallography, 1983
A computer algorithm is presented for calculating the part of the van der Waals surface of molecule that is accessible to solvent. The solvent molecule is modeled by a sphere. This sphere is, in effect, rolled over the molecule to generate a smooth outer-surface contour.

Analytic spectral functions for atmospheric transmittance calculations

Applied Optics, 1988
Analytic formulas for the transition energies, intensities, and spectral absorption coefficients of the big (most intense) band systems of H(2)O and CO(2) are presented. Analytic spectral representations of the Chappuis band of O(3), three bands of O(2), and two bands of CH(4) are also given.

Analytic calculation of electron beam isodose distributions

Medical Physics, 1984
Analytical techniques have been developed to generate electron beam isodose distributions from a modest set of experimental data. These techniques include (1) development of a compact yet powerful linear least‐squares optimization program with a graphic display of the results, (2) coordinate transformations to allow straightforward fitting of the ...

Analytic calculation of feynman amplitudes

Physics of Atomic Nuclei, 2003
A new method is proposed for calculating amplitudes of processes involving spin-1/2 fermions.The method is based on the use of the isotropic-vierbein vectors in Minkowski space and the basis spinors associated with them.The amplitudes for the electron -positron interaction processes e − e + → f ¯ f and e − e + → W − W + and the amplitude for one of the
