The thermodynamic properties of water and water vapor
(Washington, D.C. American Meteorological Society, 1941-11); MWR-069-11-0329
Extensive international research has been conducted within about the last 10 years for the purpose of ascertaining, with maximum accuracy, the thermodynamic properties of water and water vapor. Experiments were carried out ...
Determination of altitudes from the adiabatic chart and the Refsdal aerogram
(Washington, D.C. American Meteorological Society, 1936-03)
The recently-developed Refsdal "aerogram" possesses the interesting property of providing an exceedingly simple, direct and exact means of evaluating geopotential, and hence altitude, from the graph of an aerological ...
Adjustment of a telescope
(Annapolis, Maryland. Naval Postgraduate School, 1950); (4616)Ke
A telescope is adjusted for parallel rays if the cross hairs are in the focal plane of the eyepiece and if the focal plane of the objective coincides with the focal plane of the eyepiece, Under these conditions an incident ...

Combatting terrorism through fusion centers: useful lessons from other experiences?
(Taylor & Francis, 2017)
European nations might consider an institutional option in their ongoing fight against terrorism. Research on intelligence reform globally indicates that certain institutional innovations to combating terrorism that may ...
A conservative discontinous Galerkin semi-implicit formulation for the Navier-Stokes equations in nonhydrostatic mesoscale modeling
A Discontinuous Galerkin (DG) finite element formulation is proposed for the solution of the compressible Navier–Stokes equations for a vertically stratified fluid, which are of interest in mesoscale nonhydrostatic ...
Processing, deformation and failure in superplastic aluminum alloys: applications of orientation-imaging microscopy
(ASM International, 2004)
The importance of grain size refinement in enabling superplasticity is reviewed, and the current understanding of grain boundary characteristics is summarized. The application of orientation-imaging micros- copy (OIM) ...
Deformation bands and the formation of grain boundaries in a superplastic aluminum alloy
Superplastic aluminum alloys are often classified according to the mechanism of microstructural transformation during annealing after deformation processing. In Al-Cu-Zr materials, such as Supral 2004, the presence of ...
An evaluation of microstructure and microhardness in copper subjected to ultra-high strains
The microstructure and microhardness of copper subjected to large strains either using one or a combination of severe plastic deformation (SPD) processing techniques was evaluated. The individual SPD techniques used ...
Adiabatic heating and the saturation of grain refinement during SPD of metals and alloys: experimental assessment and computer modeling
Severe plastic deformation methods include equal-channel angular pressing/extrusion, high-pressure torsion, and plane strain machining. These methods are extremely effective in producing bulk microstructure refinement and ...
