Dynamic Assignment Modelling with Trips
This paper describes additional ways in which TRIPS models time-varying, or 'dynamic' effects. These include area-wide effects as vehicles move through the network,...
Experimental Study on the Rheologic Behavior of the Slurry of Viscous Debris Flow
The slurry of viscous debris flow is a kind of dense solid-liquid mixture. It has very complicated rheologic behavior. As shown in the experiment described in this paper, the slurry exhibits...
Spectral Analysis of Annual Time Series of Mountain Precipitation
In this paper we examine the statistical moments of long record, annual, precipitation time series for 19 west facing stations along the Wasatch Front, northern Utah. The mean, variance,...
Time-Dependent Behavior of FRP Lintels
This paper describes an experimental investigation into the short-term and long-term behaviors of two types of T-shaped lintels made of fiber-glass reinforced plastic with polyester or...
Transportation: New Systems for the New Century
By the end of this decade, a new coordinated transportation system for the U.S. could consist of high speed rail, maglev, regional airports and highways built solely for trucks. It would...
Time Dependent Analysis of Partially Prestressed Composite Members
The object of the paper is to develop a computer based procedure for analysis of members made up of precast prestressed concrete sections with cast-in-place topping. The procedure accounts...
Local Wind Pressures on Roofs
The paper reviews the results of the most recent research studies in the evaluation of wind pressure coefficients for the design of roof cladding elements. The effect of roof geometry...
An Expert System for Groundwater Management with Applications to Collier County, FL
This paper describes techniques used in frequency analysis, time series model building, forecasting, up-dating, and mapping. Domain knowledge of experts is transferred into the system...
Computer Program for Smoothing and Correcting Hourly Time Series Data
A FORTRAN computer program has been developed for the U.S. Army Corps of Engineers St. Louis District that automatically screens and corrects hourly time series data for gross errors and...
An Investigation of a Pumped Storage Hydropower System
In order to provide a realistic basis of determining the viability of a wind-powered hydroelectric system at a potential site, an evaluation technique has been developed. Basically, this...
The Use of Time Series Analysis to Estimate Flow Duration Curves to Assess Energy Potential for Low Head Hydro Redevelopment
The proposed hydroelectric site location has a low head potential making discharge the primary energy production component. A flow duration curve (FDC) study was commenced to generate...
Time Series Analysis of Wind Pressures on Low Buildings
A new methodology for the description of local wind pressures on the building envelope of mono-sloped roof buildings by using time series analysis is described. A simple AR(1) model has...
Efficient Methods in Time Dependent Reliability
A general and efficient method is presented for computing failure probabilities for components and systems where the uncertainties are represented by a mixture of random variables and...
Time Variant Reliability Analysis Using Bivariate Diffusive Crack Growth Models
This paper is concerned with the development of a time-dependent reliability concept. The time variant load carrying capacity, i.e., resistance, of a structure caused by fatigue is expressed...
Stage-Frequency Analysis of Closed-Basin Lakes
Devils Lake in North Dakota is used as a case study for the model development and application. The basis of the relationship developed in this study is the separation of the annual maximum...
Highway Injuries: Our Major Health Problem
Injuries are the leading cause of death in the United States from early childhood until about age 45. Motor vehicles kill more Americans age 1 to 34 than any other source of injury or...
Time Averaged Estuarine Mass Transport Equations
A methodology for deriving time averaged mass transport equations for estuaries having weakly nonlinear long wave dynamics is presented. A 2D in-plane advection-dispersion equation for...
Activity Center Development Impact Analysis
A flexible microcomputer spreadsheet analysis method is described for analyzing area-wide and localized impacts of new development in urban or suburban activity centers. The analysis approach...
Evaluation and Testing of Travel Demand Software
Transportation planners are frequently confronted with issues and concerns related to varying levels of analysis detail. Although microcomputer packages exist to analyze regional, corridor...
Transportation Network Building Using a CAD Interface
This paper illustrates how Barton-Aschman Associates, Inc, has made use of AutoCAD(TRADEMARK) on the microcomputer to digitize an existing highway network and to create a new network from...
