Fragility Curves and Seismic Loss Estimation Methodologies Based on Insurance Data
Loss data for single family dwellings from the 1994 Northridge, California, earthquake were correlated with ground motion with the aim of determining ground motion-based fragility curves....
Technology Innovation in Urban Transit System and Its Project: Development of the Small Size Subway with Linear Induction Motor
In the 1960's, Osaka City started the investigation for miniaturizing the subway for the purpose of developing an intermediate capacity transit system along the Line No. 1, which was most...
How Creative Engineers Think
Engineering giants think in a non-traditional way, combining scientific thinking with creative thinking, which results in technological thought. The author gives examples of how Gustave...
Pier Width and Local-Scour Depth
Presented here are the results of an enquiry into the effects of pier width on local scour depth. The results show that scour depth does not scale linearly with pier width unless there...
FLODRO 2.0: A User Friendly Personal Computer Package for Flood and Drought Frequency Analyses
The use of personal computers have changed dramatically the way to perform several studies related with hydrological problems. The increased capabilities of the current generation of personal...
Optimization of a Ground-Water Injection/Extraction System
This paper describes the application of linear programming to optimize the number, location, and rates of extraction/injection for a pump and treat system at a groundwater remediation...
Scour Processes Observed in Field Data
River channels scour and aggrade due to complex, interrelated natural processes that are dynamic over space and time. Channel scour is particularly difficult to predict for bridge crossings,...
A Comparison of Sediment Routing Models
In this paper the authors have compared the performance of coupled linear and non-linear methods of solution from these generic types, in order to assess their suitability for use in optimisation...
Study of Hydraulic Jump Lengths on Inclined Channel Beds
A hydraulic jump is generally used to dissipate kinetic energy of flow to protect man-made structures such as spillways, drop structures, and outlet works. It serves as a perfect location...
Bridge Repair on the Fast Track
For repair with tight deadlines, conventional approaches to inspection and repair might not be fast enough. Where the concept of design-build leaves off, the contractual solution of inspect-repair...
Statistical Response of a Class of Hysteretic Systems
The response of a hysteretic nonlinear system subjected to a filtered white noise is considered. The method of time-dependent equivalent linearization is used and the moment equations...
Propagation of Linear Gravity Waves Over Slowly Varying Depth and Currents
A detailed derivation of some kinematic and dynamic properties linear surface gravity waves-current interaction. The obtained expressions, which are exact within the framework of linear...
Comparison of Current Meters Used for Stream Gaging
The U.S. Geological Survey (USGS) is field and laboratory testing the performance of several current meters used throughout the world for stream gaging. Meters tested include horizontal-axis...
Evaluation of Six Methods for the LP3 Distribution
Six frequently used estimation methods for the Log-Pearson type 3 distribution were evaluated using both the predictive and the descriptive performance indices. Ten LP3 populations and...
Effect of Lead Shielding on Small Cask Criticality
A study was performed to evaluate gamma shield effects on criticality safety for two modern legal weight truck casks. The lead gamma shield of a small spent fuel shipping cask increases...
The Effect of Gamma Irradiation on the Volatility and Redox State of Simulated DWPF High-Level Nuclear Waste Glasses
Gamma-induced volatility of simulated DWPF high-level nuclear waste glasses is highly dependent upon the redox state of the glass. For oxidized glasses with an Fe2+/(Fe2+...
Linear Scheduling: A Practical Implementation
This paper describes the features and use of a family of planning structures that provides the basis for a superset of the traditional critical path method which includes linear scheduling....
A Rezoning Procedure for Finite Element Analysis of Rubber-like Materials
In this paper, we propose a rezoning procedure for finite element analysis of rubber-like materials. Rezoning procedures connect the distorted mesh and the newly created and undistorted...
Construction and Maintenance Decisions for Multi-Unit Deteriorating Facilities
Facilities that deteriorate over time and use can require maintenance or replacement. Selecting among replacement and maintenance alternatives for large systems of deteriorating facilities...
Measuring the Effect of Sediment Fences for Wetland Creation and Restoration in Louisiana
A sediment erosion table (SET) method has been developed to monitor changes over time in intertidal mudflat or pond elevations with an accuracy in the 1.5 mm range. The SET permitted rapid...
