Book Solution and Theoretical Evaluation of Steady state Equations in Continuous Zone Refining

Download or read book Solution and Theoretical Evaluation of Steady state Equations in Continuous Zone Refining written by John K. Kennedy and published by . This book was released on 1965 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper explains the differences and the reasons for the differences which exist between the theory of the zone-transport system of continuous zone refining as presented by W. G. Pfann and T. Abe. The identity between the mathematical model used to describe the zone-transport system and one of the models used to describe the recently reported matter-transport system is noted. Nondimensional equations for the zone-transport system are presented and the difference between the limit of alpha in the zone-void and zonetransport systems, when L sub e = 0, is correlated.

Book On the Resolving Power of Ground Mapping Radar Antennas

Download or read book On the Resolving Power of Ground Mapping Radar Antennas written by J. F. McIlvenna and published by . This book was released on 1965 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mapping of extended, cultural ground targets by an airborne radar is examined using communication theory concepts including those of the antenna transfer function and the target spatial frequency spectrum. Use of the set of transfer functions that correspond to Taylor aperture distributions and specification of the targets directly in terms of their spatial frequency spectra, permits one to examine the antenna images for quality and resolution. The results obtained indicate that resolution for a class of ground targets can be much better than is predicted by the two-point Rayleigh resolution criterion. It is also true that there can be situations in which the shape of the antenna images are quite independent of the radiation pattern. Several types of spatial noise were also included in the input spectrum to investigate noise effects on image quality and resolution. (Author).

Book On the Relative Efficiencies of Context free Grammar Recognizers

Download or read book On the Relative Efficiencies of Context free Grammar Recognizers written by T. V. Griffiths and published by . This book was released on 1965 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of diverse recognition procedures that have been proposed for parsing sentences with respect to a context-free grammar are described in this paper by means of a common device. Each procedure is defined by giving an algorithm for obtaining a nondeterministic Turing Machine recognizer that is equivalent to a given context-free grammar. The formalization of the Turing Machine has been chosen to make possible particularly simple descriptions of the parsing procedures considered.

Book Two Phosphorescences and Electron Transfer in Dye disulfhydryl Compound Complex

Download or read book Two Phosphorescences and Electron Transfer in Dye disulfhydryl Compound Complex written by Eiji Fujimori and published by . This book was released on 1965 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mercaptoethanol and dimercaptopropanol form a complex with a cationic dye. Two dyes interacting with two SH groups in the complex with dimercaptopropanol exhibit two different absorptions and two different phosphorescences. Each one of them, present at a shorter wave length, corresponds to an absorption and a phosphorescence of the complex with mercaptoethanol. The dye-dimercaptopropanol complex is more photosensitive than the dye-mercaptoethanol complex. A phototropism observed in the former complex is based on an electron transfer.

Book Directivity and Beamwidth Approximations for Large Scanning Dolph Chebyshev Arrays

Download or read book Directivity and Beamwidth Approximations for Large Scanning Dolph Chebyshev Arrays written by Charles J. Drane (Jr.) and published by . This book was released on 1965 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Directivity and beamwidth for radiation patterns corresponding to the optimum Dolph-Chebyshev design have heretofore been determined by means of formulas that, although exact, are intractable to computation and not particularly open to physical interpretation. Approximate but accurate formulas are presented here in closed form, for the purpose of easy examination and computation of directivity and beamwidth for large scannable Dolph-Chebyshev arrays. Array length, number of array elements, the spacing of these elements, and the sidelobe level desired are parameters in this study. The maximum achievable directivity for Chebyshev arrays is in principle limited, regardless of how large the array becomes. Data is given to establish the array length required to obtain a value of directivity at some prescribed level below the maximum value. Comparisons between exact and approximate theory are presented in graphical form in such a way as to illustrate the lower limits of array size for which the approximations are valid. Element spacings less than a half-wavelength are included in this study. (Author).

Book Feasible Control Computations Using Dynamic Programming

Download or read book Feasible Control Computations Using Dynamic Programming written by Stephen J. Kahne and published by . This book was released on 1965 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of Bellman's dynamic programming technique to realistic control problems has generally been precluded by excessive storage requirements inherent in the method. In this paper, the notion of state mobility is described and shown to be valuable in reducing certain classes of dynamic programming calculations to manageable size. The scheme requires one simple calculation at each stage of the process. IN many cases even this calculation may be omitted. It results in the reduction of the range of allowable state variables to be scanned. The amount of reduction varies from problem to problem. A simple example exhibits a fifty percent reduction. This corresponds to a fifty percent reduction in storage requirements for the problem. Reductions of one or two orders of magnitude appear possible for certain classes of problems.

Book State   Logic Relations in an Iterative Structure for Autonomous Sequential Machine

Download or read book State Logic Relations in an Iterative Structure for Autonomous Sequential Machine written by William F. King (III) and published by . This book was released on 1965 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The state-logic relations are determined in an iterative structure for any autonomous sequential machine. A model (unlike that of Mealy) is used in which delay is distributed throughout the machine. Theorems are presented which prescribe the interconnection of identical elements to realize any autonomous sequential behavior. Synthesis, as described here, yields a more costly machine in terms of delay elements than those of previous workers. In addition to the iterative structure, increased speed of operation is the advantage bought by the extra delay elements.

Book A Study of Band Edge Distortion in Heavily Doped Germanium

Download or read book A Study of Band Edge Distortion in Heavily Doped Germanium written by Freeman D. Shepherd (Jr.) and published by . This book was released on 1965 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Details of the energy band structure of degenerate n-type germanium were determined by analysis of fine structure in the 4.2K volt-ampere characteristic of germanium tunnel diodes. No shift in the relative energy of the conduction band minima was observed. The band edge is found to be exponentially distributed with 1/e energies of the order of 10 MeV. There appears to be an ordering mechanism among the group V impurity atoms used as substrate dopants. (Author).
