System Engineering and Risk
System engineering means many things to many people, but there is a large group of practicing engineers in the defense and energy sectors who define system engineering as a structured...

Extended Kalman Filter-Finite Element for Geotechnical Problems
A parameter identification method has been developed in geotechnical engineering problems, where the extended Kalman filter-weighted local iteration procedure is developed incorporated...

Critical Issues Related to a Combined Probabilistic Numerical Analysis of Contaminant Transport in Porous Media
Reliability algorithms provide attractive alternatives to Monte Carlo simulation and stochastic perturbation approaches for probabilistic analysis of contaminant transport in porous media....

Site-Dependence of Spatial Coherency
The spatial coherency of ground motion from nine dense arrays are analyzed to examine the site-dependence of spatial coherency. The spatial coherencies computed for arrays located on alluvium...

Estimates of Extreme Wind Distribution Tails
The assumption that extreme winds have a Gumbel distribution appears to yield unrealistically high failure probability estimates for wind-sensitive structures. For this reason we study...

Digital Simulation of Wind Load Effects
The time domain solution of the equations of motion of structures subjected to a stochastic wind field is often obtained by a step-by-step integration approach. The loading is often described...

Comparison of Wind Cross-Spectral Data with Models
Existing analysis procedures for the prediction of long-span bridge response to wind have until recently neglected the horizontal-vertical cross-spectral components of the wind under the...

Non-Gaussian Vortex Induced Aeroelastic Vibrations under Gaussian Wind
The 'lock in' aeroelastic vibration phenomenon observed for random wind excitation is modeled in a way that allows the application of the Slepian model process tool to obtain an approximation...

A Fatigue Reliability Model for Railway Bridges
A fatigue reliability model is described for safety evaluation of steel railway bridges. The model is a function of six independent random variables and can accommodate different types...

Stochastic Finite Element Analysis of a Damped Beam on Random Foundation and Subjected to Fast Moving Loads
The dynamic effect of fast moving loads on a rail is analysed by the perturbation-based stochastic finite element method. The rail is modeled as an elastic beam resting on the Winkler...

Some Modeling and Analysis Techniques for Wave Propagation in Random Media
Some mathematical modeling techniques for the problem of wave propagation in randomly imperfect periodic medium are reviewed: multiscale formulation and random evolution modeling. These...

Differential Motions in Sedimentary Valleys
The differential motions (strains), induced in sediment-filled valleys due to incident seismic waves, are investigated. The response of a two-dimensional model of an asymmetric wedge-shaped...

Probabilistic Order of Chaotic Dynamics
A chaotic dynamics system generally turns a deterministic input into a random-like output. Although the response is not directly predictable in the deterministic sense, its probabilistic...

A Statistical Method for the Reliability of Mechanical Components
The usual statistical treatment of data for the reliability of components is to fit a distribution to them and then to use this theoretical distribution for predictions. But since this...

How to Improve Writing Skills
Many papers submitted to ASCE journals are rejected because of poor writing. Moreover, the most common complaint employers have of newly graduated engineers is their lack of writing skills....

Standard Reference Evapotranspiration Calculations: REF-ET
REF-ET is a PC software program for computing standard calculations of reference evapotranspiration (E_to) and associated variables. Computations...

A Markov Chain Approach for Analyzing Palmer Drought Index
Drought is conceived as a period of below normal precipitation or moisture deficiency that would affect the social and economic activities of a region. The Palmer Drought Index (PDI) is...

Prediction of Sedimentgraph from a Small Watershed in Poland in a Changing Environment
Estimates of sedimentgraphs and temporal distributions of sediment concentrations are essential for prediction of pollutant concentrations in streams and reservoirs. In such predictions,...

Linking GIS with Hydrologic Modeling
A GIS-based methodology for conducting rapid assessments of pesticide and nutrient transport within agricultural watersheds was recently developed. This methodology is based upon the use...

Introduction to Remote Sensing for Irrigation and Drainage
Remote sensing is a rapidly emerging technology that has many potential applications to irrigation, drainage and hydrologic engineering. This paper, the first of four, introduces the reader...
