On the Impedance Method for Measuring High Electron Density and Electron Collision Frequency in a Gaseous Plasma Column PDF Author: Denis M. Coffey
Publisher:
ISBN:
Category : Electron distribution
Languages : en
Pages : 38

Book Description
An analysis of a microwave impedance method for measuring electron density and effective electron collision frequency in a plasma column is reviewed. It is evident from laboratory observations that surface polarization effects may be present in the impedance method. Such a consideration alters the form of the usual expression for the complex dielectric constant of an ionized gas. (Author).

Publisher:
ISBN:
Category : Computer-aided design
Languages : en
Pages : 30

Book Description
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.

A Discussion of the Wheeler-Feynman Absorber Theory of Radiation

A Discussion of the Wheeler-Feynman Absorber Theory of Radiation PDF Author: Ronald G. Newburgh
Publisher:
ISBN:
Category : Absorption
Languages : en
Pages : 34

Book Description
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).

Characteristic Wave Cataloguing for Ray Path Determination

Characteristic Wave Cataloguing for Ray Path Determination PDF Author: YĆ«ji Inoue
Publisher:
ISBN:
Category : Geomagnetism
Languages : en
Pages : 38

Book Description
Wave cataloguing suitable for ray tracing of a pulsed wave packet in a weakly-dissipative, horizontallystratified magnetoionic medium is described, Particular attention is devoted to the cataloguing of the various characteristic waves so that the influence of the local ionization density and collision frequency can be understood. The procedure presented is applicable under general incident conditions and complex refractive index surfaces. The Booker quartic equation is used to derive the unambiguous wave normals and wave identification is obtained from the dispersion equation. A modified CMA. diagram including collisions is illustrated. (Author).

Plurality-count Diversity Combining for Fading M-ary Transmissions

Plurality-count Diversity Combining for Fading M-ary Transmissions PDF Author: John N. Pierce
Publisher:
ISBN:
Category : Alphabets
Languages : en
Pages : 38

Book Description
The performance of a plurality-count diversity combiner for fading M-ary transmissions is analyzed, and calculated error probabilities are presented graphically for alphabet sizes of 2, 8, and 32. The performance is shown to be within 3 dB of that of an optimum square-law combiner for moderate alphabet sizes when there is no restriction on the allowable number of diversity branches. It is shown that a worthwhile saving in transmitted power can be effected by using nonbinary alphabets with plurality-count combining for the transmission of binary data. The availability of extra information from the combiner for use with error-correction is discussed.
