Simple, accurate temperature-measuring instrument
Compact instrument, composed of integrated circuits and a temperature-sensitive platinum resistor, measures temperature over a wide dynamic range. Ultimate accuracy is limited by nonlinearity of the platinum resistor. With proper calibration and current regulation to within 0.01 percent, a measurement accuracy of 0.05 percent can be achieved
Effect of reduced computer precision on a midcourse navigation and guidance system using optimal filtering and linear prediction
Reduced computer precision effect on midcourse navigation and guidance system using optimal filtering and linear predictio
Computer program resolves radiative, conductive, and convective heat transfer problems for variety of geometries
Computer program computes temperature distribution as a function of time in a given body which has been subdivided into a network of nodes. Thermal resistances and capacitances may be computed from nodal geometry

Laser power at 5 microns from carbon monoxide gasdynamic expansio
Method of stabilizing flueric vortex valves and vortex amplifiers
Inducing losses in the vortex chamber of vortex valves and vortex amplifiers resolves the problem of unstable operation caused by a sufficiently large positive feedback. Induced losses also reduce pressure gain and throttling range of vortex pressure amplifier
Tungsten fiber-reinforced copper composites form high strength electrical conductors
Tungsten fiber-reinforced copper composites have tensile strength, yield strength, and modulus of elasticity proportional to fiber content. The composites form high strength electrical conductors
Monte Carlo direct view factor and generalized radiative heat transfer programs
Computer programs find the direct view factor from one surface segment to another using the Monte carlo technique, and the radioactive-transfer coefficients between surface segments. An advantage of the programs is the great generality of problems treatable and rapidity of solution from problem conception to receipt of results
