Aiming points

American Ballistics also markets high performance, high velocity ammo in several pistol and rifle calibers, standard velocity rifle and pistol reloads and MADCAP (Mean Automatic Dispersion from a Central Aiming Point). The latter is a mylar target overlay used to measure relative accuracy, pattern dispersion and shooter proficiency with automatic weapons. ... 

Figure 45. Calculated parameters of the scattered molecules vs. initial conditions for the Nj/Ag(lll) system with i = 0.3eV, Ts = 90K, rjinit) =0K, ei = 0 . The ratios measure the orientation of the final angular momentum vector. The initial orientation of the Nj is described by 6 where where cos(6b) = 0 corresponds to side-on approach geometry and cos (0b) = 1.0 corresponds to end-on approach geometry. The impact parameter describes the initial aiming point in the unit cell with 6 = 0.0 A corresponding to an atop site and fc = 1.89 A a center site. The plots are from Kummel et al. (1988).

Teller prepared himself further at Compafiia Hill I put on a pair of dark glasses. I pulled on a pair of heavy gloves. With both hands I pressed the welder s glass to my face, making sure no stray light could penetrate around it. I then looked straight at the aim point. ... 

Above a fork in the Ota River in central Hiroshima a T-shaped bridge spanned the river and connected to the island formed by the two distributaries. The Aioi Bridge, not a war plant surrounded by workers houses, was Ferebee s chosen aiming point. Second Army headquarters was based nearby. Tibbets had called the bridge the most perfect AP he d seen in the whole damn war ... 

Little Boy exploded at 8 16 02 Hiroshima time, 43 seconds after it left the Enola Gay, 1,900 feet above the courtyard of Shima Hospital, 550 feet southeast of Thomas Ferebee s aiming point, Aioi Bridge, with a yield equivalent to 12,500 tons of TNT. 

Location of the redundant components in positions well apart from each other and not simultaneously in sight from a single virtual aiming point. 

Fortunately, process control technology is simple, mature, available , and organized to improve the reproducibility and repeatability of operations. With it, the semi-aqueous process can be rendered stable. There are two keys for success (1) identify all the appropriate aim points to validate correct process operation, and (2) always use appropriate process control technology to audit operation is on-aim. 

Average daily expenditures during the first week on the Salerno beaches were 2jo Mi and 100 M4 smoke pots and 5,000 gallons of fog oil. One of the principal diflSculties encountered was the burning glow of the smoke pots which often served as aiming points for enemy bombers. ... 

The number of coupled equations are 6(N + n) and the quantities calculated are obtained as averages over a number of trajectories which initially have randomly chosen values for the phase angles and the aiming points AX, AF. The trajectories are run on the lower adiabatic potential surface for the interaction between the atom/molecule and the solid. It is possible to include in a simple but approximate manner the effect of electronic nonadiabatic effects if the potential energy surfaces for the excited states are available. This is done by... 

For a diatomic molecule, we need also to initialize the internal degrees of freedom. Thus the center of mass motion is initialized as for the atom, i.e., R is the vector from the aiming point at the surface to the center of mass of the molecule and Fr the momentum vector in that same direction. The vector joining the two atoms r is given by... 

We avoid averaging over oscillator phase angles. Only the aiming point has to be chosen randomly. Thus quantities such as energy accommodation converge rapidly (20-50 trajectories).
