Kinetic Interpretations of First Reactivity Experiments on Lunar Basalt Samples
For the first time, water/oxygen production from Apollo program lunar samples has been experimentally demonstrated. The experiments gave extremely encouraging results as all ilmenite was...

Optical Waveguide Solar Energy System for Lunar Material Processing
This paper summarizes a study of the optical waveguide (OW) solar energy system for lunar material processing. In the OW solar energy system, solar radiation is collected by the concentrator...

The History and Present Status of Microwave Aircraft
The history of microwave-powered aircraft is reviewed from the point of view of interaction between the technology of beamed microwave power transmission and the applications for it. the...

Dynamics of Nuclear Power Plant Structures with Foundation Interaction
This paper presents analyses and conclusions pertaining to a recorded earthquake motion felt at a nuclear power plant. The objective is to obtain frequency composition, assess damage potential,...

Monitoring of Structures During Repair of Underground Utilities
A collapse of underground utilities at a power plant required the constant monitoring of the surrounding structures during excavation and replacement of the damaged pipes. A computer-based...

Overview - Electrical Substation Structures Design Guide
The ASCE Substation Structures subcommittee of the Committee on Electrical Transmission Structures (CETS) is developing a substation structures design guide. The guide discusses the analysis...

Test Experience with Heavy Angle Dead End Lattice Transmission Towers
During the past three years, the Electric Power Research Institute's Transmission Line Mechanical Research Center has conducted full scale tests on three 500kV heavy angle dead end lattice...

Assessment and Upgrade of an Older Transmission Line
This paper discusses the various tools and procedures which have been used to assess and upgrade an older 130 kv tower line. The purpose of the assessment was to determine the line compliance...

ASCE GUIDE for Design of Guyed Transmission Structures
This paper describes the contents of a new ASCE guide for the selection and design of guyed electrical transmission structures. Guyed transmission structures present unique analysis and...

Investigating the Behavior of a Lattice Structural Section
Tests were conducted on a fully instrumented lattice section assembled using various connection types (bolted or welded). The results of this study show that bolt slippage can have a major...

Fatigue Damage Accumulation Under Stochastic Stress Histories
An extensive simulation study was performed to generate random Gaussian stress time histories from power spectral densities (psd's). The psd's of time histories were selected to represent...

Practical Application of Tuned Liquid Damper for Tall Buildings
Performance of TLD, based on the full-scale measurement of an actual tall building, is discussed in this paper. Wind induced vibration of the SYP Tower was measured during a gusty day,...

Helium-Supported Hangar for a Small Solar-Powered Airship
For the IGA Expo '93 the Institute for Statics and Dynamics of Aerospace Structures, University of Stuttgart, together with Stuttgart Solar e.V. developed a solar-powered airship. For...

Three Dimensional Modelling of Estuarine Sediment Transport
This paper describes the sediment transport module in the three-dimensional finite element model TELEMAC-3D which uses the operator splitting technique to solve the shallow water and transport...

Numerical Modeling of Advective and Diffusive Transport in the Rappahannock Estuary, Virginia
A laterally integrated, two-dimensional real-time model, consisting of linked hydrodynamic and water quality models, was developed to study hypoxia in the tidal Rappahannock River, a western...

Boston's Backup Water Supply
For fifty years, Boston's sole real source of water has been the Hultman Aqueduct, but now final design is almost complete on the MetroWest Supply Tunnel, a new, larger conduit...

The TMA Wave-Energy Constraint and Cohesive Shore-Profile Shapes
A relation by Andreanov between wave-energy loss and nearshore slope, when combined with the TMA wave-energy constraint, is shown to closely approximate the classical Bruun/Dean shape....

The Re-derivation of the NDBC Wind-Wave Algorithm
The National Data Buoy Center (NDBC) currently manages a network of 57 moored buoys and approximately 7 Coastal-Marine Automated Network stations on off shore platforms which transmit...

Observations of Wind Wave Growth by ERS-1 SAR
Spatial variations of ocean waves can be observed from space-borne synthetic aperture radar (SAR) images of ocean surface. For a steady offshore wind, the growth of wind wave from an upwind...

BPA Realtime Hydrologic Forecasting System for the Columbia River Basin
Bonneville Power Administration (BPA) markets and distributes the hydroelectric power produced at 30 federal projects in the Columbia River Basin. In order to plan the System's coordinated...
