Development of a large space robot: A multi-segment approach
A multi-segment robot is developed as a concept for use in space based construction operations. The multi-segment robot is envisioned as a member of a class of large space robots, or space cranes, used in the assembly of ...
Recovering elastic moduli of nonlinear anisotropic annular membranes from interior measurements of deformation and pressure
We investigate the problem of inferring elastic moduli of nonlinearly elastic membranes from interior measurements of deformation and pressure. We begin by formulating a model of membrane deformation under a vertical force ...
Steady state distillation calculations: An investigation of computer techniques and an examination of results
This work has been divided into two parts. The first is concerned with methods of computation suitable for use with digital computers for distillation problems with one feed and two product streams. Two methods were ...
Vapor-liquid equilibria in the system hydrogen-nitrogen-carbon monoxide
Vapor-liquid equilibrium compositions for the system hydrogen-nitrogen-carbon monoxide were determined at -310°F, and -280°F and -240°F from 300 psig to the critical. PVT data for hydrogen were fitted to the ...
Effects of the decay of sulfur-35 on some electrical properties of cadmium sulfide semiconducting films
The vacuum behavior of radioactive and non-radioactive semiconducting films of CdS has been studied as a function of time in order to determine the effect of radioactive doping. Radioactive films containing S35 were made ...
Low temperature vapor-liquid equilibrium in light hydrocarbon mixtures: Methane-ethane-propane system
Experimental equilibrium data have been determined for 175 mixtures of methane, ethane, and propane. The investigation included temperatures from 50°F to -200°F and pressures up to the critical. A vapor recycle ...
A study of alumina silicon fluoride combinations as hydrocarbon conversion catalysts
The purpose of this work was to study the influence of certain variables in the preparation of an alumina-silicon-fluoride complex on its behavior as a cracking catalyst.
