The Effectiveness of Telecommuting as a Transportation Control Measure
This paper examines the potential of telecommuting as a strategy for managing travel demand. In particular, the paper focuses on the travel and air quality implications of telecommuting....
Load Duration and System Effects in LRFD for Wood Construction
The wood industry is developing a Load and Resistance Factor Design (LRFD) speciification for wood construction using probabilistic concepts. An analysis based on statistical models for...
The Use of Sophisticated Three-Dimensional Numerical Models in Weather Modification Efforts
Understanding of the complex interactions between the mesoscale and cloud environment and between microphysical and dynamical processes within clouds can be substantially increased with...
Predicting Water Demand in Agricultural Regions Using Time Series Forecasts of Reference Crop Evapotranspiration
Overall, it can be said that the time series model developed in this study did provide superior forecasting results for the Brawley, CA, site. This indicates that the monthly reference...
Streamflow Forecasting Using Trainable Neural Networks
In this investigation the practicality of applying a backpropagation neural network to modeling watershed response characteristics is examined. Two separate tests were performed. One test...
HOV Lessons
As traffic congestion worsens, transportation planners are struggling to squeeze out every last bit of available roadway capacity. High-occupancy vehicle lanes are one solution, but aren't...
Wind Tunnel Modeling of Time-Dependent Drift Topography
The aeolian wind tunnel is a useful tool for investigating not only the saltation physics of wind-driven sand, soil or snow, but also for determining the time-dependent development of...
Preliminary Calculations of Release Rates from Spent Fuel in a Tuff Repository
Time-dependent release rates of Tc-99, I-129, Cs-135, and Np-237 have been calculated for wet-drip and moist-continuous release modes from the engineered barrier system of a potential...
Extracting Dynamics from Ocean Wave Time Series Data
Recent developments in chaotic dynamics have indicated that qualitative information of a dynamical system can be extracted from the observation of a single time series as the time series...
Three-Dimensional Blood Flows Associated with Intra-Aortic Balloon Counterpulsation
Three-dimensional blood flow processes associated with intra-aortic balloon counterpuslation (IABP) are calculated using a Cray YMP supercomputer. The mathematical model incorporates a...
Crack Growth Stability in Ice
The mechanics of stable, time dependent crack growth as a function of geometry and increasing crack length in saline an freshwater columnar ice are examined in this paper. Experimental...
A Time-Dependent Microplane Model for Creep of Cohesive Soils
The microplane model is used in this paper to describe the time-dependent (creep) behavior of cohesive soils (clays). The constitutive equations are defined on each of a set of microplanes...
Effect of Shell on Beach Performance: Examples from the West-Central Coast of Florida
Time-series analysis of beach profiles and sediment analysis along the Pinellas County coast of Florida over a 2-yr. period shows that shell abundance has an influence on beach performance....
Engineering Methods for Predicting Beach Profile Response
This papers contains a review of so-called 'engineering methods' for predicting beach profile change based on equilibrium profile concepts. In the first part...
Modelling of Cross-Shore Flow and Morphology
A one-dimensional, time-dependent model is presented which describes the evolution of wave groups and associated long waves over an arbitrary profile, in a short-wave averaged sense. Model...
Modelling of Cross-Shore Transport
The validity of cross-shore sediment transport modelling in terms of time-averaged velocities and concentrations has been investigated....
Simulation of Bedload Transport of Marine Gravel
Using combined current meter and acoustic measurements, detailed concurrent time series of instantaneous bedload transport rates and flow turbulence have been obtained. The duration, interval...
Bedload Transport Measurement by Imaging of Tracers
A dyed-sand tracer technique is developed for investigation of bedload under laboratory oscillatory flows. Imaging of the tracer with high speed photography allows the creation of time...
Morphodynamics of the Isles Dernieres Barrier Shoreline, Louisiana: 1984?1989
An aerial videotape mapping system was used to monitor spatial and temporal variability of the coastal morphology along the Isles Dernieres barrier shoreline. Between 1984 and 1989, nine...
Effects of Temperature and Mean Cell Residence Time on Enhanced Biological Phosphorus Removal
The effects of temperature and mean cell residence time (MCRT) on biological phosphorus and nitrogen removal were investigated by operating pilot-scale continuous-flow activated sludge...
