Wind Effect on Oblique Motion of Two Bodies in a Uniform Flow
The wind effect on the general translational motion of a circular cylinder through an inviscid and incompressible fluid, conveyed by a uniform flow at infinity, in the vicinity of another...

Routes to Chaos of a Vertically Rotating Pendulum
Each blade of a mechanical shredder may be modeled by a pendulum whose pivot rotates in a vertical circle. The transition to chaos of small periodic motion about radial lines us the driving...

An Elastoviscoplastic Model for High Strength Concrete
An elastoviscoplastic model of overstress type is proposed for high-strength concrete in this study. With its viscosity parameters determined with experimental data from the split-Hopkinson-pressure-bar...

Mechanical Properties of High Performance Concretes
This paper presents some of the initial results of a 4-year research project on mechanical properties of high performance concretes with particular reference to highway applications. High...

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...

A Mars 1 Watt Vortex Wind Energy Machine
Ever since Viking I and II landed on the surface of Mars in the summer of 1976, man has yearned to go back. But before man sets foot upon the surface of Mars, unmanned missions such as...

Artificial Gravity Augmentation on the Moon and Mars
Extended visits to the moon and Mars will require a base on the surface. Exploration of small planetary neighbors will depend upon the development of a life support system that prevents...

Denver International Airport Fabric Roof Design
The design of Denver's Landside Terminal Complex for the new Denver International Airport, called for some far reaching vision coupled with imaginative building technologies. Because of...

Opportunities for Fixed Rail Service to Airports
With the increase in air passenger traffic and related ground access congestion many cities are examining potential links between regional transit systems and their airports. A working...

Major Public Transportation Investments as Development Projects: Old Colony Railroad
In 1988, the Massachusetts Executive Office of Transportation and construction (EOTC) developed a set of guidelines for traffic studies in conjunction with the state's environmental review...

The Last Freeway
Ever since what's now known as the Pasadena Freeway was completed in 1940, Los Angeles has been synonymous with the freeway�first with the ease and speed of transport it represented...

Housing Chernobyl Relocatees
The April 1986 explosion of the Chernobyl Nuclear Power Plant Reactor 4 in northern Ukraine Commonwealth spread nuclear contamination assisted by southerly winds across hundreds of miles...

Effectiveness of Implemented HOV Lane System
Individual carpool lanes have proven their worth on a case by case basis. Now, in California and across the country, systems of HOV lanes are being planned for urban areas dealing with...

The Monitoring of Water Conservation Behavior and Attitudes in Southern California
Seldom are the effects of public information programs monitored and analyzed in a sound, systematic manner. Information on the impact of investments in public information programs is essential:...

Estimates of Extreme Wind Distribution Tails
The assumption that extreme winds have a Gumbel distribution appears to yield unrealistically high failure probability estimates for wind-sensitive structures. For this reason we study...

Sampling Errors in U. S. Extreme Wind Records
A study of design level extreme wind speeds showed that sampling errors were the primary cause of station to station variability. A method for decreasing sampling errors in design wind...

A Fatigue Reliability Model for Railway Bridges
A fatigue reliability model is described for safety evaluation of steel railway bridges. The model is a function of six independent random variables and can accommodate different types...

Stochastic Finite Element Analysis of a Damped Beam on Random Foundation and Subjected to Fast Moving Loads
The dynamic effect of fast moving loads on a rail is analysed by the perturbation-based stochastic finite element method. The rail is modeled as an elastic beam resting on the Winkler...

Summary Conclusions & Recommendations of the 1991 Washington State Ports and Transportation Systems
Since 1975, the Washington Public Ports Association and Washington State Department of Transportation (WSDOT) have conducted periodic performance assessments of the state's ports, waterways,...

Alameda Transportation Corridor
The Alameda Transportation Corridor is a significant new commitment on the part of the Ports of Los Angeles and Long Beach to improve and increase rail and highway access and capacity...
