Abstract: This paper deals with the problem of a practical filter for discrete-time, dynamic systems with unknown parameters whose variation cannot be estimated in advance. The modeling errors caused by ...

Abstract: A unique seasonal collection method of sky radiation energy was proposed. This method is especially effective in the humid area where the radiative cooling could not be expected. To collect ...

Abstract: Characteristic forms of differential equations for wave propagation in nonlinear media are derived directly from equations of motion and equations which combine the constitutive equations and the ...

Abstract: The Hertz problem for a rigid spherical indenter on a viscoelastic half-space was studied by Lee and Radok [1] in which the radius a(t) of the contact area is a monotonically increasing function of time t. Later...

Abstract: This paper is concerned with an approach for identifying the input and observation noise covariances in continuous linear systems. The estimates of noise covariances are evaluated as the mean ...

Abstract: The generally applicable approximate analysis for pad-type nozzles was shown statistically to be reliable through the use of the design of experiments. The focus was on membrane stresses due ...

Abstract: The finite element analyses are carried out for the several piping components (D /T ≧ 100) subjected to in-plane or out-of-plane moment. For the stress evaluation of the chemical plant piping systems, ANSI B31...

Abstract: Cavitation inception observations were made in the DTNSRDC 36-inch water tunnel on three axisymmetric headforms with and without various turbulence stimulators installed. Direct transition measurements, ...
