The derivation of coefficients for the transfer functions of maximally flat time-delay networks generally begins from an infinite
series approximation of the ideal transfer function. This thesis presents two alternative methods that are particularly suited to cases
involving an unequal number of poles and zeroes in the transfer function. The...
A recently developed statistical model for first-order scattered fields is used to predict
the normalized covariance function of an underwater acoustic signal backscattered by a
hypothetical school of fish. The fish school is configured as an oblate spheroid with the
individual fish Poisson distributed within the school.
Empirical covariance functions...
The Pacific Coast variety of Douglas-fir was investigated.
The samples were tested using both forced and free vibrations. Transverse
vibrations were introduced by excitations on the side of the
samples. Forced vibrations were applied from 5000 to 0 hertz by a
vibration generator, and free vibrations were initiated by a...
The purposes of this study were to determine whether the generally accepted procedure of campus elections as a method of choosing student government representatives (1) appears to encourage the candidacy of students who hold perceptions of the university environment similar to other students who do not choose to become candidates;...
An instrument which measures current from D.C. to 50 megahertz
by clipping a transformer core around a current carrying conductor
is discussed. A Hall device, which is installed in the core cross-section, detects the flux in the core. This Hall device in conjunction
with an amplifier is used to null...
The dynamics of land use in the State of Oregon are simulated
on a digital computer. The introductory chapter outlines the complex
nature of the problems facing the post-industrial society and argues
that the scientific and professional estates share in the responsibility
for public policy formulation. The second chapter .presents...
A method for the synthesis of bilateral networks is
presented. A new algorithm for the realization of basic
cut-set matrices is developed. This is done by the
following procedure:
1) We form submatrices, M[subscript j] (i), j= 1,2,..., of the
given cut-set matrix, such that M[subscript j](i) satisfies
the properties...
