  • Analytical and experimental thermal analysis of multiple heat sources in integrated semiconductor chips
    Lindsted, R. D.; DiCicco, D. A. (IEEE, 1972-05)
    Because of the complexity and interconnection density of today's integrated circuit chips, experimental measurement of individual transistor or diode junction temperatures under typical powered conditions has become ...
  • On Schwarz canonical form for large system simplification
    Lal, M.; Mitra, R.; Jain, A. (IEEE, 1975-04-01)
    Recently a new technique for the reduction of a large-order dynamical system, using Schwarz canonical form, has been proposed [1]. It is presently shown that the above is essentially a frequency domain technique for which ...
  • Identification of nonlinear systems in frequency domain
    Shanmugam, K. Sam; Jong, M.T. (IEEE, 1975-11-01)
    A frequency domain technique for identifying a class of nonlinear systems is presented. The class of nonlinear systems we consider in this paper consists of a power series nonlinearity sandwiched between two linear systems ...
  • Experimental results of the remote sensing of sea-surface salinity at 21-cm wavelength
    Thomann, Gary C. (IEEE, 1976-07-01)
    The complex dielectric constant of sea water is a function of salinity at 21-cm wavelength, and sea-water salinity can be determined by a measurement of radiometric temperature at 21 cm along with a measurement of thermodynamic ...
  • Authors' reply
    Lal, M.; Mitra, R. (IEEE, 1976-08-01)
  • Custom programming/analysis in the small business environment
    Cary, T. (IEEE, 1976-09)
    As has often been stated, a business of any size can be considered as a general system,8,11,13,28,29,20,31with identifiable external inputs and outputs typically consisting of goods, services, energy, money, and information. ...
  • Two dimensional tests of GA(W)-1 and GA(W)-2 airfoils at angles- of-attack from 0 to 360 degrees
    Satran, Dale R.; Snyder, Melvin H. (Wichita State University.Wind Energy Laboratory, 1977-01)
    Tests of the GA(W) - l and GA(W)-2 airfoils were conducted in the 2- D test section of the Wichita State University 7' x 10' low speed wind tunnel to determine the lift , drag, and pitching moment coefficients of the ...
  • The zoom FFT using complex modulation
    Hoyer, E.A.; Stork, R. (IEEE, 1977-05-01)
    A recent paper by Yip discussed the zoom transform as derived from the defining equation of the FFT. This paper simplifies the concepts and removes some of the restrictions assumed by Yip; ie., the total number of points ...
  • An algorithm for the two dimensional FFT
    Hoyer, E.A.; Berry, W. (IEEE, 1977-05-01)
    Conventional two dimensional fast Fourier transforms become very slow if the size of the matrix becomes too large to be contained in memory. This is due to the transposition of the matrix that is required. This new algorithm ...
  • On combinational networks with restricted fan-out
    Kodandapani, K.L.; Seth, S.C. (IEEE, 1978-04)
    Fan-out-free networks of AND, OR, NOT, EXOR, and MAJORITY gates are considered. Boolean functions for which such networks exist are defined to be fan-out free. The paper solves the following problems regarding the fan-out-free ...
  • Two-dimensional zoom FFT
    Stork, R.; Hoyer, E.A. (IEEE, 1978-04-01)
    The concept of the zoom FFT (a more efficient algorithm which allows zooming in on a narrow segment of the spectrum while preserving its frequency content) is extended to the two-dimensional case. The technique is further ...
  • A cellular array for multivalued logic functions
    Kodandapani, K.L.; Setlur, R.V. (IEEE, 1978-11)
    An algebraic generalization of the well-known binary q-function array to a multivalued q-function array is presented. It is possible to associate tree-structure realizations for binary q-functions and multivalued q-functions. ...
  • An optimal frequency domain filter for edge detection in digital pictures
    Shanmugam, K. Sam; Dickey, Fred M.; Green, James A. (IEEE, 1979-01-01)
    Edge detection and enhancement are widely used in image processing applications. In this paper we consider the problem of optimizing spatial frequency domain filters for detecting edges in digital pictures. The filter is ...
  • Optimal control systems with low sensitivity to small time delays
    Sawan, M. Edwin; Cruz, J. B. (IEEE, 1979-12-01)
    The problem of reducing trajectory sensitivity to small time delays is considered. State and output feedback gains are computed, so that the system performs optimally with low sensitivity. The delay is assumed to be expected ...
  • Undetectability of bridging faults and validity of stuck-at fault test sets
    Kodandapani, K.L.; Pradhan, D.K. (IEEE, 1980-01-01)
    The study of bridging faults (or short circuits that occur between conducting paths) has become increasingly important with the advent of LSI technology. To date, only a very few papers have been published on this topic. ...
  • A digital quarter square multiplier
    Johnson, Everett L. (IEEE, 1980-03)
    An application of the quarter square multiplication technique used in analog computing is proposed for digital multiplication. Significant savings in storage requirements for ROM- implemented product tables are demonstrated. ...

    Graham, A.R. (IEEE, 1982-10-18)
  • Decoupling of large scale systems
    Shah, Dipak C.; Sawan, M. Edwin; Tran, Minh T. (IEEE, 1984-06-06)
    Linear shift invariant large scale discrete-time multivariable systems whose inputs and outputs are strongly interacted, are considered. The designing of compensators to decouple these systems is presented.

    Shah, Dipak C.; Sawan, M. Edwin; Tran, Minh T. (IEEE, 1984-06-06)
    Linear shift invariant discrete-time systems with slow and fast modes are considered. Singular perturbation techniques are used to obtain the slow subsystem and the fast subsystem. A reduced-order control is designed for ...
