Estimation Of Time-Varying Correlation Functions, G. R. Cooper, Helmut Berndt Mar 1963

Estimation Of Time-Varying Correlation Functions, G. R. Cooper, Helmut Berndt

Department of Electrical and Computer Engineering Technical Reports

The need for estimating the auto- or crosscorrelation functions of nonstationary random processes frequently arises in communication and self-adaptive systems. In most situations only one sample function can he observed over finite time. It is the purpose of this work to establish a firm theoretical basis for such a measurement of time-varying correlation functions, and the emphasis here is on suitable estimation procedures rather than specific measurement techniques. Second order stochastic processes are used as a mathematical model. The minimum mean square error between a weighted time average and the true (ensemble average) correlation function is investigated. This procedure leads …

On The Application Of Liapunov’S Second Method To The Stability Analysis Of Time-Invariant Control Systems, G. P. Szego May 1962

On The Application Of Liapunov’S Second Method To The Stability Analysis Of Time-Invariant Control Systems, G. P. Szego

Department of Electrical and Computer Engineering Technical Reports

The investigation of the stability properties of the equilibrium point of a control system poses various problems -which, even if conceptually very similar, vary greatly in difficulty and in the methods appropriate for their solutions. The first and easier problem is what we may call the stability analysis of a completely defined system: given a particular control system to decide what stability properties its equilibrium point has. The second problem deals with a system having a fixed configuration but with parameters whose numerical values are to be determined. The problem is to find the boundaries in the parameter space at …


The Variable Gradient Method Of Generating Liapunov Functions With Application To Automatic Control Systems, John E. Gibson, D. G. Schultz Apr 1962

The Variable Gradient Method Of Generating Liapunov Functions With Application To Automatic Control Systems, John E. Gibson, D. G. Schultz

Department of Electrical and Computer Engineering Technical Reports

The contribution of this thesis is the introduction and development of the variable gradient method of generating Liapunov functions. A Liapunov function, V, is considered to be generated if the form of V is not known before the generating procedure is applied. Two previous attempts at the generation of Liapunov functions to prove global asymptotic stability for nonlinear autonomous systems have been made. These attempts are summarized and evaluated in some detail, as they form the basis for the variable gradient approach proposed in this thesis. It is assumed that the system whose stability is being investigated is represented by …

The use of the methods and the devices (CTL and MRP) are extended to measure moisture content of soil for various other geotechnical purposes. Laboratory compaction mold and Shelby tubes serve as CCs where density are measured using conventional methods


The Scattering Of A Plane Electromagnetic Wave By A Finite Cone, C. C. Rogers, F. V. Schultz Aug 1960

The Scattering Of A Plane Electromagnetic Wave By A Finite Cone, C. C. Rogers, F. V. Schultz

Department of Electrical and Computer Engineering Technical Reports

This paper treats the solution of the -vector Helmholtz equation for the case of a plane electromagnetic wave at ’nose-on' incidence, on a perfectly-conducting cone of finite size* The solution presented is exact and in the form of an infinite series of spherical harmonics. The expansion coefficients of the series are determined by a set of an infinite number of equations involving an infinite number of unknowns. A discussion and numerical investigation of the field singularities at the tip and edge of the cone are included* as well as graphs of the associated Legendre functions of non-integral degree, P1(cos θ), …
