Currently, the majority of collision avoidance systems on fighter aircraft depend on the pilot taking action whenever a warning is issued by the manual system. Any future substantial reductions in mishap rates will require extending the collision avo

Over the past forty years, the number of fighter aircraft controlled flight into terrain (CFIT) accidents per flight hour has not improved despite the addition of multiple manual warning systems. The Air Force Research Laboratory (AFRL) has undertake

The development of an all-terrain ground collision avoidance system (GCAS) in conjunction with a maneuvering terrain following (TF) system is discussed. Both systems use a digital terrain database. The unprecedented pilot interaction available with t

Autonomous collision avoidance is necessary if Unmanned Aerial Vehicles (UAVs) are to "blacken the sky" in massed attacks, accompany manned fighters on combat missions, and transition civil airspace. These vehicles will, in some manner, have to "see

The design of an automatic air collision avoidance system (Auto ACAS) is intended to prevent air-to-air collisions between air vehicles. The Auto ACAS is not to replace existing designs such as the Traffic Alert and Collision Avoidance System (TCAS)

The IBM‐2+ Configuration Mixing method has been expanded, in order to consider several multiparticle‐multihole (np‐mh) configurations simultaneously. The various np‐mh configurations obtained by exciting pairs of protons and/or neutrons acros

The IBM-1 + f-boson model is described and systematically applied to the nuclei 154Sm, 156Gd, 158Gd, 158Dy, 162Dy, 168Er, 172Yb, 178Hf, and 182W. Reasonable agreement with available energies and B(E3) transition rates is obtained in all cases except

The even isotopes of mercury have been systematically studied using the Interacting Boson Model (IBM). In order to treat shape coexistence in the light isotopes, two separate IBM calculations were performed with different configurations, which were s

Two new absolute transition rates are reported for the nucleus144Sm following an (α, α′) Coulomb excitation study. They are B(E3; 3−→ 0+)=(38±3) W.u. and B(E1;3− → 2+)=(2.8±0.4)×10−3 W.u. This large E1 matrix element, along with the
