Odors: The Other Effluent
Neighbors object to unpleasant odors emitted at wastewater treatment plants, and dealing with such odors requires tact as well as technology. The operators and engineers must listen to...
From Guesswork to Guarantee?
Maser describes a project to determine the effectiveness of radar and infrared thermography in detecting deterioration of asphalt overlaid bridge decks. The project, sponsored by the New...
Detecting the Defects
According to estimates, for every dollar spent on preventive maintenance of the infrastructure, $10 will be saved by avoiding emergency repairs after major structural failures. Technologies...

Real-time Animation of Construction Activities
As a result of 3-D computer modeling, the availability of geometric data in an electronic form makes possible the use of computers for purely construction activities in ways that were...
Real-time Monitoring of Heavy Equipment in Open Pit Mines
This paper reports on a system with local intelligence to interpret on-board signals. Existing sensors, pressure switches, warning lights, relays, and on-board monitoring systems provide...
Journal of Materials in Civil Engineering
The Journal of Materials in Civil Engineering covers the development, processing, evaluation, applications, and performance of construction materials in civil engineering....
Stochastic Optimization of Reservoir Systems Operations
This paper addresses the stochastic optimization of real-time monthly operations of multi-reservoir systems by Dynamic Programming. A two-stage optimization framework that consists of...
Optimal Operation of the Savannah River System
This paper presents an application of a stochastic control method to the real time operation of the Savannah river system which includes three reservoirs and is expected to meet energy...
Roller Compacted Concrete Mix Design for Pamo Dam
Pamo Dam is designed as a 265 foot (81M) high gravity dam that will be located on the Santa Isabel Creek in San Diego County, California. RCC volume will be approximately 491,000 cubic...
Accommodation of Large Trucks: Traffic Control Issues
The objective of this paper is to identify ways that large trucks can be accommodated safely and efficiently through traffic control. Traffic control is herein defined as encompassing...
A Stochastic Model for Low-Cycle Elastic-Plastic Fatigue Crack Growth
In this paper a stochastic process approach is considered to represent the random nature of the low-cycle (elastic-plastic) fatigue crack growth process. A semi-Markov renewal model is...
Recent Thoughts on Probabilistic Fatigue Crack Growth
We briefly review recent results of analysis of fatigue crack growth data. Implications of this analysis are presented, and reasons are advanced in favor of increasing the dimension of...
Modeling Fatigue Crack Growth Resistance, dN/da
In the fracture mechanics approach to fatigue, da/dN is correlated with the cyclic range of the stress intensity factor, ?K; the resulting relation, da/dN=f (?K), is commonly called the...
Stochastic Modeling of Fatigue Crack Growth
A new lognormal fatigue crack propagation model has been presented in which a two-dimensional state vector has been employed to introduce experimentally observed history dependence of...
Markov Chains & Soil Constitutive Modeling
The focus of this research effort is the construction of a mathematical framework to assist in understanding the role of uncertainties in the constitutive/dynamic behavior of soils. The...
Statistics of Concrete Shrinkage Test Data
The paper reports a large series of concrete shrinkage tests which can be used for statistical purposes. The series involves two groups of 36 identical cylindrical specimens, with a diameter...
First-Order Reliability Analysis of Groundwater Flow
A method for stochastic analysis of groundwater flow based on the first-order reliability approach is presented. The method is well suited for problems in which statistical information...
