Mean Square Stability of Linear Gyroscopic Systems Under Combined Harmonic and Stochastic Excitations
This paper examines the mean square stability of linear gyroscopic systems under both harmonic and stochastic parametric excitations. The intensities of both excitations and correlation...
Detection of System Nonlinearity
A method for detection of linear/nonlinear characteristics of mechanical systems excited by stationary Gaussian processes is presented. Linear systems under consideration show always a...
Identification of Power Spectra?Linear and Nonlinear Approaches
Linear dynamical filter systems driven by white noise can be used for the generation of stationary and Gaussian processes. A linear approximation method proposed by W. Wedig is presented...
Fatigue Test Using Multi-Notched Specimen and its Reliability Analysis
This paper presents a fatigue testing method using a multi-notched test specimen for the purpose of estimating the distribution function of fatigue crack initiation life by a small number...
Recent Results on the Effect of Gamma Radiation on the Durability and Microstructure of DWPF Glass
The effect of gamma radiation on the durability and microstructure of a simulated nuclear waste glass from the Savannah River Site has been carefully investigated. Three large pieces of...
Optimal Operation of Multiple Reservoir Systems
In this paper a temporal decomposition approach is presented to solve a long term deterministic model for a multi-reservoir system. Through relaxation the long term problem is broken into...
Estimating Lake Inflows for Storage by Linear Programming
The Lower Colorado River Authority (LCRA) recently completed a Water Management Plan for the lower Colorado River Basin in Texas. In developing the Plan, a daily river flow routing procedure,...
Operational Remote Sensing of Snow Cover in the U.S. and Canada
The Office of Hydrology of the National Weather Service maintains a cooperative National Operational Hydrologic Remote Sensing Center, based in Minneapolis, to generate remotely sensed...
A Regionalized Rainfall-Runoff Stochastic Model
The single area unit hydrograph model is used to develop a distribution model which accommodates the uncertainty in rainfall over the catchment. By categorizing the available rainfall...
Real Time Flood Forecasting in New Zealand
Current New Zealand real time flood forecasting research developments are described. Successful flood forecasting using a linear system transfer function technique is described. Promising...
Vibrations of Linearly Tapered Cantilever Beams
Originally published in: Journal of the Engineering Mechanics Division, ASCE, EM2, April 1962, pp. 95-123...
Finite Element Computations on a Linear Systolic Array
This paper describes a linear systolic architecture designed specifically for finite element computations. Examples of various sparse matrix and vector operations are given. Applications...
Parallel Computation for Linear Programming
In this paper, the basic Simplex algorithm is reexamined. Computational steps which can be done in parallel are identified, and a parallel version of the Simplex method is implemented...
Fourier Series Expansion on Determination of Response Bound of Beam
Fourier series expansion is suggested to discrete the continuous vibrating system by regarding Fourier constants as generalized displacement parameters. The orthogonal merit to the terms...
Gamma Exposure from Rn Progeny in GAC Units
An investigation into the gamma exposure rate generated by granular activated carbon (GAC) water treatment units focused on ten sites that covered a range of source radon (Rn) in water...
A Tracer-Model for Morphological Simulations of an Estuary
Numerical models for longterm morphological simulations are traditionally based on assumptions like vertical integration of the flow and transport equations and their decoupled treatment....
General Formulation of Best Hydraulic Channel Section
The best hydraulic channel section is determined by using Lagrange's method of undetermined multipliers. The approach presented is more general & easier to apply than...
Geostatistics: From Mining to Hydrology
Geostatistics originated in the mining industry to help estimate the amount of metal contained in a block or ore, from a systematic sampling of the block. In this paper, the major geostatistical...
Multisite Hydrocomplex Optimization
A multisite complex is analysed in northern Quebec to decide the level of equipment needed that will supply firm energy at the best possible unitary price. Four possible sites were chosen...
An Analysis of Cavitation Damage in a Francis Turbine Operating Under Small Opening Condition
In this paper some new formulae are derived to estimate the pressure and the relative velocities in the crown and the band regions of the Francis turbine runner operating under any gate...
