Water Surface Flow and Exchange Induced by a Bubble Plume
Aeration is a common method to increase dissolved oxygen in the water of stratified (or non-stratified) lakes. In this method compressed air is injected at some depth, and gas is transferred...

Oxygen Mass Transfer to Flowing Ground Water Using Oxygen Microbubbles
Mass balance and transfer of oxygen has been studied from oxygen microbubbles to low dissolved oxygen ground water passing through variously configured pilot scale vertical slice test...

Ground Water in the Pacific Rim Countries
This proceedings, Ground Water in the Pacific Rim Countries, consists of papers presented at the Symposium held in Honolulu, Hawaii, July 23-25,...

Symposium on Ground Water
This proceedings, Symposium on Ground Water, contains papers presented at the International Symposium on Ground Water in Practice, held in...

Seismic Practices for the Air Transportation System: Evolution and Needs
The seismic performance of air transportation systems is reviewed. The evolution of seismic design criteria and practices for major air transportation system elements is discussed. The...

An Analytical Framework for Minimizing Freeway Incident Response Time
The reduction in incident delay is an important aspect of any freeway management program as it results in substantial savings to roadway users. This paper presents an integrated decision...

Optimal Ramp-Metering Control for Freeway Corridors
The paper discusses an optimal ramp-metering control model wherein a corridor is discretized into small road sections, with density as the state variable and ramp metering rates, the control...

Application of Control Theory to Regulate Traffic Flow on Periurban Ringways
Two on-ramp metering strategies are compared by a simulation study for the Boulevard Peripherique in Paris. The first one is a local strategy, based on linear feedback control theory....

Design and Evaluation of Multi-Band Progression Schemes
Multiband is a new arterial progression scheme that has the capability to assign each directional road section with an individually volume-weighted band. The method offers to the traffic...

Car Wars?The DOTs Strike Back
HNTB is developing integrated computer systems utilizing standard hardware and software platforms coupled with graphical user interfaces for traffic management systems (TMS). Rapid, user-friendly...

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...

Dynamic Stochastic Equilibrium Model in Multiple Vehicle Type Transportation Networks
In this study, a multi-vehicle type dynamic stochastic user equilibrium model (called MDSUE model for abbreviation) is developed. By using MDSUE model, the prediction of departure rates...

Dynamic Estimation of Freeway Demand Patterns and a Stochastic Programming Approach to Freeway Ramp Metering
Controlling the rate at which vehicles are allowed to enter a freeway from the freeway's on-ramps has become a standard method for reducing the impact of both recurring and...

Aircraft Traffic Mix Analysis: Damage Factors and Coefficients
Historically, traffic mix analyses have been based upon the use of the critical or most damaging aircraft. The damage effects of other aircraft are either ignored or empirically incorporated...

Landing on Frictionless Surfaces
Who in his right mind would deliberately land an airplane on a frictionless surface? Unfortunately, professional pilots occasionally encounter situations where the friction between rubber...

Alternative Airfield Pavement Quality Control
In recent years, the cost of maintaining quality control during airfield construction projects has concerned airport operators and engineers alike. This paper addresses the possibilities...

Time Management for Engineers and Constructors
This book is the first in a series which focuses on engineers' management needs. It presents time management principles for the practicing engineer and constructor, in a concise,...

Approximate Reliability Analysis of Highway Bridges Under the Action of Random Vehicles?In Relation to an Interchange Bridge of China
In relation to an interchange curved bridge of China, a simple method by FSE for analysis of stochastic vibration has been proposed. The random vibration characteristics of bridge structures...

Reliability of a Suspension Bridge Under Traffic Flow
The problem of reliability of a single-span spatial suspension bridge under random highway traffic is considered. The displacements of the bridge are described by coupled, non-linear,...

Rethinking Flood Control Channel Design
Until recently, the standard method of flood control was channelization�converting a natural stream to a uniform channel cross section. But this single objective approach is coming under...
