Estimating Network Model Parameters from Mail Survey Data
Network models are generally based on a four-step modeling process; trip generation, trip distribution, modal split, and trip assignment. Microcomputer implementations of these steps have...
A PASSER II-90 Postprocessor for Detailed Analysis of Arterial Traffic Control Parameters
Many preprocessors have been developed for traffic signal operation software to ease the tedious data input process or to perform error trapping on the input data. However, work to date...
Factors Controlling Strong Ground Motion and Their Associated Uncertainties
Of special interest in strong ground motion modeling is a quantification of the degree of influence specific physical parameters have on the computed motions. Associated with the model...
Results from the Second Performance Assessment Iteration for the Greater Confinement Disposal Facility
The Greater Confinement Disposal (GCD) facility was established by the Nevada office of the Department of Energy (DOE) in Area 5 at the Nevada Test Site for containment of waste inappropriate...
Flow and Transport in Hierarchically Fractured Systems
Preliminary results indicate that flow in the saturated zone at Yucca Mountain is controlled by fractures. A current conceptual model assumes that the flow in the fracture system can be...
Automatic Calibration of 3D Finite Differences Model Parameters? Application to the Finnsjon Site (Sweden)
Calibration of 3D finite difference model parameters is usually carried out using a noon-automatic 'manual' procedure until observed heads, for instance, are simulated with a sufficient...
Pipe Network Optimisation Using Genetic Algorithms
A new optimization technique of generic algorithms has recently been successfully applied to pipe network optimization. In this paper a parametric analysis is carried out of the genetic...
The Optimum Parameter Selection for 4-Point Time Domain Integration Schemes
In this paper, a general method of time dimension discretization based on the idea of finite element is presented for dynamic analysis. Two kinds of recurrent formulations are derived...
Reducing Ambiguity in Qualitative Reasoning
Qualitative reasoning derives the behavior of a physical system using a representation of the fundamental principles for the domain. In qualitative reasoning parameters are mapped into...
The Use of Numerical Rule Processors in Engineering Calculations
A Numerical Rule Processor uses a declarative approach to the processing of engineering calculations. The rules which link the parameters are set out in a separate rule base and the order...
Some Considerations About a Coastal Lagoon (RJ-Brasil) Trophic Level
The growing urban occupation in coastal areas has generated environmental disturbs such as the eutrophication of semi-enclosed water bodies. The Marapendi Lagoon, located at a fast developing...
A Method for Classifying Land Loss by Geomorphology and Process
There is great debate as to the causes of land loss in Louisiana and the restoration/preservation solutions that should be implemented. Much of the controversy can be attributed to a lack...
Sandy Accumultive Forms Within the Black Sea Coastal Zone
Most of the sandy accumulative forms of the Black Sea are within Ukraine territory. There are various types of these forms differing in morphology, dynamics, source of material, interaction...
Wave Diffraction Patterns Behind Detached Breakwaters
This paper presents a theoretical model to examine the wave diffraction behind detached breakwaters subjected to regular oblique waves. The method of solution is an eigenfunction expansion...
Image Measurement Systems for Traffic Analysis?Specifications, Survey, and Limits
This presentation is concerned with systems for extraction of road traffic information from visual images. The extracted information ranges from macro-scale, cumulative traffic parameters...
Statistical Analysis of Extreme Hydrological Droughts
The study examined several works about extreme droughts for their validity with different parameters by the statistical experimental method. The results showed that the analytical method...
Stochastic Modeling for Drought Analysis Using Thomas-Fiering Lognormal Three Parameter Model
Three variations of Thomas-Fiering log normal 3-parameter(TFLN3) model are fitted to the unregulated south-west monsoon-dependent monthly streamflows measured at Krishnarajasagara (KRS)...
Robust Estimators in Hydrologic Frequency Analysis
This paper applies a specific robust estimation procedure known as 'trimming' in flood frequency analysis. The trimming technique consists in censoring the series of recorded floods by...
Incorporating GIS Technology in Standard Flood Hydrology Applications
The potential for application of Geographic Information Systems (GIS) to hydrologic analyses has received increasing attention in recent years. Published literature on hydrologic applications...
A Comparison of L-Moments with Method of Moments
A comparison of the Conventional Moments Method (CMM) with the L-Moments Method (LMM) for selecting a distribution is made. Five distributions GEV (Generalized Extreme Value), LNO (Lognormal),...
