Interpreting Debris-Flow Hazard from Study of Fan Morphology
The deposits, stratigraphy, and surface morphology of debris-flow fans are a record of past debris-flow activity, and as such can provide useful information about debris-flow hazards....
Mapping Debris-Flow Hazard in Honolulu Using a DEM
A method for mapping hazard posed by debris flows has been developed and applied to an area near Honolulu, Hawaii. The method uses studies of past debris flows to characterize sites of...
Structural and Non-Structural Debris-Flow Countermeasures
Debris-flow can potentially occur for almost any torrents whose gradient is steeper than a given critical value and the frequency at which the debris-flow occurs depends on geological...
Recent Developments in Safety Research from the Gas Research Institute
Recent developments in Safety Research, as supported by the Gas Research Institute (GRI), have consisted primarily of hardware-oriented applications to various gas industry safety operations....
Pierce Transit's Experience with an Alternate Fuel Compressed Natural Gas January-December 1992
At the end of 1992, Pierce Transit's CNG fleet consisted of 30, 40-foot Orion buses, 19 ElDorado Buses, on GMC 'New Look' bus, one 1990 Chevy Celebrity, and one Collins Shuttle van. As...
Automated Crack Detection System Implementation in ARAN
An automated road surface crack detection system has been integrated into the Automated Road Analyzer (ARAN). The acquisition system features controlled lighting through strobe lights...
Comparative Analysis of Different Systems for a New Rail Line in Copenhagen, Denmark
A new Mass Transit System is to be built in Copenhagen, Denmark. The Copenhagen Public Bus Company, HT, and the Danish State Railways, DSB, have each carried out feasibility studies. Conventional...
A Public Transport System Based on Light Electric Cars
This paper presents the concept under development in France of a novel transportation system based on fleet of small public cars under supervision from a central computer. These public...
New Tram System in the Osaka South Port Area
The New Tram is a fully automated guideway transit system, first introduced in Japan as an urban transportation system by the Osaka Municipal Government. It has operated smoothly without...

The Copper-Clad Library
The design vocabulary for the new Phoenix Central Library includes saddlebags, power bellies, tensegrity and corrugated siding. The saddlebags are copper-clad, steel-framed core structures...
Letter from Oman
The bonanza days of the 1980s are over, but the oil-rich sultanate continues to be a rewarding, if challenging, market. Oil remains a focus of investment, and the government is planning...
Rail Revival
Rail transit appears to be on the upswing. More than 30 cities are building, extending or seriously considering new rail-transit systems, according to a recent report from the Regional...
Environmental Constraints Associated with Dredging in Southern California
The U.S. Army Corps of Engineers, Los Angeles District, is responsible for the maintenance dredging of twelve harbors along the Southern California coast, ranging from Morro Bay in the...
Coal-Gas Conundrum
Manufactured gas from coal brought streetlights and clean cooking fuel to the late Victorian era, but a hundred years later their legacy isn't quite so beneficial. Investigators...
Dynamic Response Analysis of Pile Foundations by Using Variational Calculus
Various approaches have been developed for the frequency-domain dynamic response analysis. The one proposed by M. Novak (1974) is simplest of all and yet produces the results very close...
Effect of Active Control on Closely Spaced Natural Frequencies
Current problems in structural control involve structures with closely spaced natural frequencies (M.J. Balas, 1983). The purpose of this paper is to show how control affects a structure...
Cables and Cranes for a Flexible Lunar Transportation System
This paper will discuss the results of preliminary research on a cable-based transportation system for the moon. The paper will address the principles of cableway design and will present...
Mobile Continuous Lunar Excavation
The purpose of this paper is to explore the two main problems regarding current approaches to lunar mining and to recommend three candidate solutions which will be shown to have potentially...
Measuring Vibration in an Advanced Composite Beam with Localized Internal Fiber-Optic Strain Sensors
Two optical fibers embedded with different configurations were used separately as strain sensors to measure the natural frequencies and modal amplitudes of a cantilevered graphite/bismaleimide...
