Spatial and Temporal Precipitation Characteristics in Southwest Idaho
The USDA-ARS, Northwest Watershed Research Center operates a precipitation gage network on the Reynolds Creek Experimental Watershed in southwest Idaho. Analysis of the 30-yr (1962-1991)...

Construction and Maintenance Decisions for Multi-Unit Deteriorating Facilities
Facilities that deteriorate over time and use can require maintenance or replacement. Selecting among replacement and maintenance alternatives for large systems of deteriorating facilities...

Active Guideway Systems
Many automated people movers which have been developed or studied in France or in other countries belong to the category of active guideway systems. This paper describes characteristics...

Knolle Magnetrans: A Magnetically Levitated Train System
New permanent magnet materials can now withstand repulsion indefinitely without loss of magnetism. Vehicular magnetic levitation occurs when a track and the undersides of vehicles thereon...

Nonlinear Wave Runup on Large Circular Cylinders
Various design methods for computing nonlinear wave runup on a large-diameter circular cylinder are presented. First, empirical correlations are developed between the observed maximum...

Second-Order Hydrodynamic Interactions Between a Pair of Vertical Cylinders in Irregular Waves
A complete second-order solution is given for the hydrodynamic forces on a pair of bottom-mounted, surface-piercing, vertical circular cylinders in bichromatic seas. The constant structural...

On Distributed Processing Applications in Finite Element Analysis
Computer architectures may be classified by the relationship between their instruction and data streams (SISD, SIMD, MISD, MIMD) and the locality of memory (shared, local). Distributed...

Stochastic Response of a Caster-Mounted System
The response statistics of a caster-mounted system with white noise excitation are estimated using the generalized equivalent linearization method. The displacement and velocity covariances...

Estimating Damage and its Influence on Fracture Toughness
To estimate damage in a quantitative manner, a technique used whereby six values of linear strain are measured on a material element as a function of hydrostatic pressure. The high precision...

The Theory of Elasticity: 1950-1992 and Beyond: Concluding Remarks
Forty years ago the theory of elasticity could be completely characterized by A.E.H.Love in his monumental treatise as an effort to reduce to calculation the internal state of stress produced...

Inflation Instability of Cylindrical Membranes
A new procedure which investigates inflation instability of cylindrical nonlinear membranes is developed. The general characteristics of inflation instability are described. An efficient...

Generalized Isoparametric Coordinate Determination Scheme for Finite Element Mesh Generation
A simple and accurate scheme for determining the coordinates of node points located within the interior of planer regions discretized with quadrilateral elements is described. A novel...

Structural Optimization in a Distributed Computing Environment

Linearisation and Offshore Fatigue Reliability
In determining the force effects due to wave action on offshore structures it is conventional to use an equivalent linearisation to convert wave velocities to forces via Morison's equation....

Optimal Discretization of Random Fields for SFEM
A new method for discretization of random fields (representation in terms of random variables) is introduced based on the principle of optimal linear estimation theory. The method is more...

Stochastic Finite & Boundary Element Simulations
Stochastic constitutive properties are important in real-world design-analyses. Therein the spatially varying random coefficients in field equations necessitate rather unconventional computational...

Linear System Spectral Moments Determination
The stationary response of a linear system to random excitation is considered. A previously developed approach is extended to be applicable for the determination of both even and odd order...

Evaluation of Seismic Soil Response Using Stochastic Linearization
This paper discusses the use of stochastic linearization to non-degrading soils. First, the Bouc-Wen model parameters are reviewed. Monte Carlo simulation results are compared with the...

Low-Cycle Fatigue Prediction for Ramberg-Osgood Type Materials
The prediction of low-cycle fatigue crack growth is successfully made by an equation employing the J-integral range. This equation, originally proposed by Dowling and Begley, is analogous...
