This book was released on 1965 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well known that in communicating over randomly time-varying channels, a receiver which performs a channel measurement can make a better decision than one that does not. It is shown that a channel-measuring system improves system performance even when the channel characteristics are fixed only during the present message interval. The randomly time-varying channel studied is that of a Rayleigh fading medium with independently fading mark and space channels whose fading is fixed over one baud interval but is independent from baud to baud. The transmission system is a modified frequency shift keying (FSK) system such that during a portion of a baud interval the mark and space frequencies are always transmitted so as to act as reference signals. For the above system, the following characteristics have been established: (a) Optimum receiver configuration, (b) Optimum ratio alpha of information energy to total signal energy as a function of total available signal-to-noise ratio for a single fading channel, (c) Asymptotic optimum alpha for an M-diversity channel, (d) Error probabilities for (b) and asymptotic error probabilities for (c) for alpha opt as a function of total signal-to-noise ratio. The asymptotic results show that by using reference techniques the order of diversity is effectively doubled. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The absorption of ozone in the 9.0 micron region of the infrared spectrum, due to transitions from the ground state to the v1 and v3 states, has been studied. This report gives the numerical results of an anlysis of the spectrum including transition frequencies and perturbed intensities ordered by quantum number and by frequency. Calculated and observed special contours are included.

Available in PDF, EPUB and Kindle. Book excerpt: The following paper represents work to date on the deformation method for quadratic programming and thus may be regarded as a sequel to Zahl, S. (1964) A Deformation Method for Quadratic Programming, Research Note AFCRL-63-132. It gives an explanation of a modified Iverson programming language and uses this to give a detailed algorithm for the Zahl Deformation Method of Quadratic Programming.

Available in PDF, EPUB and Kindle. Book excerpt: The quantum-mechanical ground-state problem for three identical particles bound by attractive inter-particle potentials is discussed. For this problem it has previously been shown that it is advantageous to write the wave function in a special functional form, form which an integral equation which is equivalent to the Schrodinger equation was derived. In this paper a new method for solving this equation is presented. The method involves an expansion of a two-body problem with a potential of the same shape as the inter-particle potential in the three-body problem, but of enhanced strength.

Available in PDF, EPUB and Kindle. Book excerpt: The Wheeler-Feynman absorber theory of radiation is reviewed. A proof is offered to show that a sum of advanced and retarded effects from the absorber can provide the origin of radiative reaction. This proof is different from and perhaps simpler than that of Wheeler and Feynman. From arguments of momentum and energy conservation the necessity of the absorber for the emission of radiation is demonstrated for three cases. (Author).

Book excerpt: A theory of hydromagnetic ionizing waves has been developed which is valid in the region in which gas pressure is negligible, compared with magnetic pressure. The theory takes into account the energy expended in partial ionization of the gas behind the wave. The usual high conductivity boundary condition behind the wave is not employed. The electric field in front of the wave is taken as a parameter. Results of this theory are compared with available experimental measurements, and show good agreement. (Author).

This book was released on 1965 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, rigorous electromagnetic theory is used to determine the nose-on radar cross section of a perfectly conducting cone of finite height. The end cap of the cone is assumed to be a segment of a s spherical surface with center at the apex of the cone. Numerical results have been obtained for a cone having a total apex angle of 30 degrees and for values of [kappa alpha] ranging from 0.0259 to 5.18, where [kappa]=2 [pi]/[lambda] and [alpha] is the radius of the base of the cone. Siegel's Rayleigh method and by using Keller's modified geometrical optics as well as with experimental results obtained by Keys. The comparisons are instructive below [kappa alpha] = 3.2, the apparent upper limit of validity of the present results -- p.[3].

Download or read book Magneto ionic Coupling in an Inhomogeneous Medium written by Yūji Inoue and published by . This book was released on 1965 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The propagation of electromagnetic waves in a horizontally stratified layer of gyrotropic medium is discussed. Derivation of a comprehensive representation for magneto-ionic coupling coefficients allows interpretation of the physical significance of the coupling. Introduction of an invariant quantity for an inhomogeneous medium becomes an important guide for numerical solutions of the wave equation. Numerical results of magneto-ionic coupling coefficients are presented. Based on region properties, characteristic wave types are defined: for the isotropic region, linearly polarized waves are used; for the anisotropic region, elliptically polarized waves generally are applied.
