ROBOSIM: A Simulation Package for Robots
ROBOSIM was developed first in a VAX environment. Using PC's with a terminal program capable of emulating a TEKTRONIX 4014, students can create robots, see them graphically,...

A Minimal Input Computer Aided Manufacturing Program for Personal Computers
The author presents here an algorithm developed in Pascal for an integrated two and a half dimensional CAD/CAM system. The geometry and the tool paths are defined simultaneously, thereby...

CAD and Video Teleconferencing Network Development
The Institute for Telecommunication Sciences is developing a prototype network to demonstrate the integration of a variety of services and methods for fulfilling Navy shipbuilding requirements....

Environmental Risk Assessment at a Gas Utility
Over the past 10 years, Southern California Gas Company (SoCalGas) has developed an environmental risk management program to mitigate or eliminate the potential health risks to employees,...

Monte Carlo Simulations of Uncertainties in Risk Assessments of Superfund Sites Using Crystal Ball?
Most health risk assessments for Superfund sites combine a series of worst case assumptions to derive a 'point estimate' of risk that is 'conservative,'...

Radon Resistant New Construction Practices
This paper highlights the basic principles for building radon-resistant houses and it groups the construction techniques into four categories, i.e., the barrier approach, soil ventilation...

Cost of Radon Control Measures in New Construction
Installation of a radon prevention system in new construction increases costs to builders and to homebuyers as well. Builders and/or their engineers will need to assess different approaches...

Treatment Plant Modifications to Conserve Energy and Improve Performance
Creative funding along with thorough planning and design contributed to the successful energy conservation program at the Willow Lake Wastewater Treatment Plant, Salem, Oregon. By funding...

QSAR Based Expert System For Environmental Hazard Management
This study was done to investigate the feasibility of developing an Expert System for application in environmental hazard management and control. The specific objective of the study was...

Analysis of Model Uncertainty Using Bayesian Monte Carlo
Bayesian Monte Carlo analysis combines Bayesian inference with standard Monte Carlo techniques to provide improved estimates of the uncertainty in water quality model parameters and results....

Peat Filtration for Oil Removal
An investigation was carried out to assess the potential of horticultural peat produced in Saskatchewan as a filter medium in treating five oil-in-water emulsions (standard mineral oil,...

Effect of Concentration on the Biological Degradation of Petroleum Hydrocarbons Associated with In Situ Soil-Water Treatment
Sandy soil samples contaminated with weathered JP-5 jet fuel were mixed with uncontaminated sand to provide a concentration gradient from 187 to 1565 mg total petroleum hydrocarbons (TPH)/Kg...

Biological Treatment of PAHs in Soil Residues in Simulated Land Treatment Systems
The lower molecular weight compounds (2 and 3 ring PAHs) are readily degraded by microorganisms. The heavier molecular weight PAH (polycyclic aromatic hydrocarbon) compounds (4, 5 and...

Irrigation and Drainage Practices
Salinity causes many problems in agriculture, by lowering production or requiring more intensive management on farms, or by degrading off-farm soils and waters. This paper describes causes...

Hydrologic Methodology for Evaluating Urban Development
It is recommended that a hydrologic methodology be utilized that contains sufficient parameters to enable the user to evaluate the impact of the changes to the watershed resulting from...

OMADSS?Operations and Maintenance Advanced Decision Support System
This paper presents a summary of the development of a prototype advanced decision-support system for operation and maintenance of dams and irrigation facilities. To set the development...

Parameter Identifiability in Conceptual Rainfall?Runoff Models
Computers have played a major role in the evolution of hydrologic rainfall-runoff models. Besides providing the computational power required for the simulation of the complex interacting...

Risk Management of the Ottawa River System
The Ottawa River System is a large-scale and complex system comprising 30 major reservoirs and 43 generating stations and has a long history of flooding that extends throughout the basin....

Graphical Canal Model for System Operators and Planners
Contra Costa Water District operates the Contra Costa Canal, part of California's Central Valley Project. Hydrocomp, Inc. developed an interactive graphical model of the canal...

Biological Methods Petroleum Hydrocarbons Cleanup
Cleanup of the ground water and soils from hydrocarbon spills has mainly focused on air stripping and activated carbon for ground-water treatment, and vapor extraction and excavation followed...
