Stresses in Open Section Fiber Reinforced Composite Beams Under Constant Shear Loading
A strength of materials approach from the ply level is used to derive expressions for stresses in statically determinate open section composite beams subjected to constant shear loading....

Laboratory Testing of Mechanical Rock Bolts
An analytical solution to a boundary value problem of a clamped cylindrical panel with anti-symmetric angle-ply laminations subjected to transverse loads is presented. Sanders' kinematic...

Design Codes for Lunar Structures
The American Institute of Steel Construction (AISC) Manual of Steel Construction is a codification for the design and construction of steel structures. It includes information, some tabular...

Conceptual Design of Modules for a Lunar Base
This paper describes the development of cubically shaped aluminum modules which could be variously arranged to form living and working quarters for a lunar base. The module components...

Structural Characterization of an Articulated-Truss Joint
A first generation space crane articulated-truss joint was statically and dynamically characterized in a configuration which approximated an operational environment. The articulated-truss...

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...

Lunar Surface Mining Equipment Study
In response to the Space Exploration Initiative (SEI), a large number of lunar base scenarios have been proposed by various members of the research community. The National Aeronautics...

The Effect of Multiple Compliant Layers at the Fiber-Matrix Interface on Residual Thermal Stresses in Metal Matrix Composites
The large mismatch in thermoelastic properties of the fiber and matrix phases in advanced metal matrix composites, coupled with high consolidation temperatures, produces severe residual...

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...
