Mineral Liberation and Beneficiation of Lunar High-Ti Mare Basalt, 71055: Digital-Imaging Analyses
Knowledge of the abundance of various lunar minerals and the ability to effectively beneficiate thee minerals are important requirements for effective utilization of lunar resources. SEM/EMP...
Reservoir Estimates for the Sulpicius Gallus Region
Estimates presented here show that 1.1?109 metric tons of oxygen could of produced from one of the enriched areas that have been detected by spectrographic...
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...
Lunar Oxygen Production in a Hydrogen Cold Plasma
This paper examines the concept of oxygen production from unbeneficiated lunar regolith using a non-equilibrium or 'cold' hydrogen plasma. An experimental investigation has indicated that...
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...
Onboard Image Processing With Transputers
A transputer based onboard computer for planetary vehicles is being designed in the KFKI Research Institute for Particle and Nuclear Physics (RMKI), Budapest, Hungary. In this paper we...
An Inflatable Antenna for Space-Based Low-Frequency Radio Astronomy
Antennas for a low-frequency orbiting radio telescope must have minimal problems in deployment, a directional beam, and a wide-angle scanning capability. Inflatable antennas with deposited...
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...
Seismic Renewal of Civil Infrastructure Systems
Almost all civil infrastructure systems are vulnerable to natural hazards such as earthquakes. The paper presents a broad perspective of the research needs for seismic renewal of the infrastructure...
On some Problems of the Multicriteria Optimization of the Spatial Grid Structures
One can not think contemporary structure designed without consciously complying with optimization methods. Creative activity of engineers have to be optimal or semi-optimal. It is necessary...
Damage Tolerance Analysis in Structural Rehabilitation
The rehabilitation of existing structures requires an evaluation by the structural engineer of past performance to determine the extent of existing damage. Following evaluation of the...
Structural Analysis for Structural Design
This paper presents a simple extension to conventional structural analysis that serves to provide additional information that is of significant use to the structural design process. Specifically,...
Computer-Aided Structural Engineering Software: The Status of Concurrent Engineering
Concurrent engineering encompasses computer-aided engineering (CAE), multidisciplinary CAE (MCAE), computer-aided design and drafting (CADD), computer-aided manufacturing (CAM), computer...
Digital Signal Processing Techniques for Active Structural Control
In the past, implementation of active structural control strategies employing PC-based hardware has been problematic due to excessive computational times required for processing the measured...
Directional Wave Data ? Measurements and Modeling Coast of Florida Erosion and Storm Effects Study
The U.S. Army of Corps of Engineers, Jacksonville District, and the Florida Department of Enviromental Protection are co-sponsors of a study to evaluate the coastal processes along the...
New Technology in Coastal Wave Monitoring
The Coastal Data Informational Program (CDIP) is an extensive network for monitoring waves along the Pacific coastlines of the US. The system has evolved substantially since its inception...
Optical Remote Sensing of Wave Surface Kinematics
The measurement of the directional properties of surface slopes, velocities and accelerations is difficult, even in the laboratory, under conditions of steep, random and short-crested...
The Use of Crumb Rubber Modifier in Hot-Mix Asphalt
This paper summarizes the literature on the use of CRM as an additive in HMA. Wet and dry processes are discussed and the objective of each explained. Material, design and construction...
Development of Hydro-Scheduling Model for Optimal Joint Operation of Multi-Reservoir Systems
Multipurpose reservoirs in a reservoir system are not limited to supplying ample amounts of water and electricity, but also provide other water demands such as flood control, navigation,...
Probabilistic Characterization of Droughts
The Palmer Drought Severity Index (PDSI) uses a set of meteorologic and hydrologic variables to create a numerical value for drought severity. The index values are grouped into drought...
