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...

Finite Element Large Deflection Analysis of Cylindrical Shells with Different Types of Cutouts
Nonlinear finite element is used to find the elastic buckling load and the maximum deflection for cylindrical shells subjected to unsymmetrical pressures due to wind. These shells are...

In-situ Release of Solar Wind Gases from Lunar Soil
A concept is described which has the potential to perform the in-situ heating of the lunar regolith in order to release the solar wind gases. The poor thermal conductivity of the lunar...

Isotopic Separation of ?He/4He From Solar Wind Gases Evolved from the Lunar Regolith
The potential benefits of 3He when utilized in a nuclear fusion reactor to provide clean, safe electricity in the 21st century for the world's inhabitants...

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...

Very Low Frequency Radio Astronomy from Lunar Orbit
This paper discusses the use of very low frequency aperture synthesis as a probe of astrophysical phenomena. Specifically, the science achievable with the Lunar Observer Radio Astronomy...

A Novel University-Industry-Government Partnership
The Ohio Aerospace Institute (OAI) is a Consortium of nine universities in Ohio, the NASA Lewis Research Center (LeRC) in Cleveland, the Wright Laboratory (WL) at the Wright Patterson...

Nowcast Protocol for the Great Lakes Forecasting System
The Great Lakes Forecasting System is a cooperative federal-university undertaking designed to implement a predictive system for each of the Great Lakes. The desired forecasts concentrate...

A Coastal-Ocean Hindcast/Forecast Model
Flows in the coastal oceans are produced by interactions of different components: tides, winds, buoyancy discharge from estuaries, topography and remote forcing of deeper-ocean origin....

Modeling Nearshore Currents in the Vicinity of the Endicott Causeway, Alaska
The Endicott Causeway connects two oil production islands on the southern side of Stefansson Sound, about 5 km offshore of the Sagavanirktok River delta, to the mainland of the Alaskan...

Modeling Tidal and Wind Driven Circulation in Sarasota and Tampa Bay
As part of an effort to quantify the effects of hydrodynamics on water quality within Sarasota Bay, Tampa Bay and their adjoining waters, a field and modeling study of circulation and...

A Three-Dimensional Simulation of Buoyancy and Wind-Induced Circulation and Mixing in the New York Bight
A three-dimensional simulation of the circulation and mixing in the New York Bight has been conducted, forced by (i) wind stress for the year 1987 and monthly-mean heat fluxes at the sea...

Effects of Wind on Circulation in Los Angeles-Long Beach Harbors
A three-dimensional hydrodynamic model was applied previously (Vemulakonda and Butler 1989) to Los Angeles-Long Beach Harbors to determine tide and wind-induced circulation. The model...

Estimation of Wind Fields for Coastal Modeling
Wind is an essential driving force for waves, circulation, and storm surge in coastal and estuarine areas. As with other horizontally 2-dimensional models, Corps of Engineers' (CE) numerical...

Tide- and Wind-Driven Flushing of Boston Harbor, Massachusetts
The flushing of Boston Harbor, a shallow, tidally dominated embayment with little fresh water input, is investigated using a depth-averaged model. The modeled tidal currents exhibit strong...

A Predictive Model of the Currents in Cleveland Bay
A two-dimensional (depth-averaged) numerical model is proposed to describe the hydrodynamics of Cleveland Bay and is used to investigate the water circulation within the Bay. By utilizing...

Probability Model of Load Exceedances under Cyclic Loadings
A probability model for nonlinear load exceedances subjected to a Poisson process with reversible cyclic load pulses was developed and is presented in this paper. A reversible cyclic load...

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...
