Calculator obtains the Rail and Z Scale dimensions on the tape-controlled Sundstrand milling machine. It provides computer with depth information required to process numerical control programs which, in turn, provide the tapes for operation of N/C milling machines.
Computer programs for rapidly computing approximate ephemerides of minor planet or artificial satellites
Perturbation method of computing optimum trajectories on hybrid and digital computers
Operating parameters and separation of nucleotides on pellicular ion exchangers investigated by liquid chromatographic system
Double ionization cross section of He when bombarded by protons calculated using Born approximation, noting energy dependence
Discriminator in nuclear particle detection system distinguishes nuclear particle type and energy among many different nuclear particles. Discriminator incorporates passive, linear circuit elements so that it will operate over a wide dynamic range.
Computer program for rapid mission analysis of Apollo Block 2 environmental control system radiators
Modified Fourier transform for calculating human operator describing functions
Neutron interaction behavior of beryllium oxide and molybdenum reflectors for nuclear reactors
Secondary electron emission from gas covered metal surfaces, discussing results of neutral beam investigations
Algorithm for programming language grammars conversion into pushdown store automata translators
Explore the source record for details and available documents.
Analysis of a typical nonlinear electrohydraulic servo-model establishes the dynamic-performance capabilities of servo-actuation systems.
Valve is insensitive to fluctuating sense pressure. It remains in full-open position until the supply pressure is removed.
New logic circuits have response times no longer than 10 nanoseconds and drain only milliwatts of power. The family includes AND and NAND gates and forms the basis of all logic functions. The basic circuits are used in various types of digital-data-processing systems.
Fuel loading requirements and resulting neutron energy spectrum after adding lithium nitride, hafnium, tantalum, and tungsten to molybdenum reflected critical assembly
Methods for increasing speed of binary addition by decreasing carry propagation time
