Critical Filters for Impervious Soils (Paper introduced by Lorn P. Dunnigan)
Remediation Site Prioritization by the Risk Ranking and Filtering Method
The risk ranking and filtering (RRF) method, developed for ranking critical components of the NASA Space Shuttle, is a possible framework for the prioritization of hazardous-waste sites...
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...
Forecasting Instabilities in Groundwater Parameters
A multiprocess Kalman filter recursive procedure is used as a tool for modeling and analysis of noisy groundwater series in order to detect abrupt fluctuations and instabilities in the...

Forecasting Behavioral Response to a Repository from Stated Intent Data
To forecast repository-induced behavior from surveys of behavioral intention, we develop a model of the relation between stated intent and actual propensity. This model relies heavily...
Application of Kalman Filtering to Groundwater Flow in Finite Heterogeneous Aquifers
A stochastically based methodology using Kalman filtering is presented for the optimal estimation of hydraulic properties in finite heterogeneous aquifers. This is achieved by applying...
Response Triscpectrum for a Yielding Structure
Simulation is used to obtain information about non-Gaussian aspects of the absolute response acceleration of a bilinear hysteretic oscillator with an excitation which is Gaussian white...
Pilot-scale Trickling Filter Nitrification at the Longmont WWTP
Nitrification rates in trickling filters can be affected by influent organic matter, filter length, and hydraulic loading rate. The effects of these parameters on nitrification rate were...
A Case Study in Sludge Handling
When the Wyoming Valley Sanitary Authority (WVSA) converted its operation to a secondary treatment plant in 1988, something important was missing. That something was a method to handle...
Pressure-Time Method Using Modern Practices
Over the past twenty years, Hydro-Quebec has modernized the pressure-time method of flow measurement, a method which is generally economical but sometimes difficult to apply. Starting...
Prediction Method of Concentration Distribution of Groundwater Pollutants Using a Field Monitoring Network System
A method based on the extended Kalman filter is developed to identify the parameters of a two-dimensional stochastic convective-dispersion differential equation and to predict in real-time...
A New Approach for Real-Time Prediction of Traffic Demand-Diversion in Freeway Corridors
An adaptive method is developed for real-time prediction of demand and diversion of traffic flow at on-ramp areas of freeway corridors. The prediction method explicitly treats the time-variant...
Observation and Modeling of Mobile Environment
Perception of the environment in a mobile robot is a difficult task. Other moving objects and various changes in the environment and motion of the robot must be handled together. Control...
