A simplified radiation detector was designed which employs an activated continuous front surface consisting of either the diffused or barrier type of semiconducting material with a grid structure on the nonactivated side of the detector. Its form may be either a rectangular coordinate or a polar coordinate system.
Effect of propellant sloshing upon stability of rocket having simple coordinate system with accelerometer
Inviscid gas flow over nose region of supersonic yawed axisymmetric blunt body treated by integral relations in body oriented coordinate system
Ascent and descent abort flight corridors for orbital transport vehicles - two dimensional equations of motion for point mass vehicle derived in circular earth coordinate system
Dimensionless differential corrections and proper coordinate system for generalized preflight guidance analysis
Iterative transformation of chromaticity coordinates of Munsell samples into another coordinate system with transformed value spacing in accordance with perceptual color spacing
FORTRAN 4 program /P1-GAS/ calculates the P-O and P-1 transfer matrices for neutron moderation in a monatomic gas. The equations used are based on the conditions that there is isotropic scattering in the center-of-mass coordinate system, the scattering cross section is constant, and the target nuclear velocities satisfy a Maxwellian distribution.
Differential motion equations of probe numerically integrated in rectangular coordinate system for probe ephemeris
Long-period librations of Trojan planetary orbits in rotating three-body coordinate system
Charged particle motion in static magnetic fields without axial symmetry derived, employing Lagrange equation in transformed coordinate system and Alfven motion
Position and shape of neutral sheet in geocentric solar magnetospheric coordinate system from geomagnetic tail measurements
Component star in close binaries nonsynchronous rotation effect on limiting surface, noting difficulties associated with certain coordinate systems
Transforming Hansen lunar theory by referring satellite motion to almost ideal coordinate system, using general perturbations method
Program computes the spacecraft look angles and the slant range, which define a spherical coordinate system located in the spacecraft body. The program is designed to reduce data from the Lunar Module Missions and to output desired information.
Mathematical model and a digital computer BLITZ language programming technique computes coefficients of quadric equations describing cylinders, paraboloids, ellipsoids, or planes with any orientation to a reference system, coordinates of a vector, and coefficients of quadric surfaces which limit the surface of three-dimensional space.
Thermal plasma motion in magnetic dipole field defined by direction in coordinate system of continuity and momentum equations
Algorithm for Navier-Stokes and continuity equations used to derive curvilinear coordinate system
