Remotely controlled or tele-operated robots are playing an increasing role in military, law enforcement and industrial operations. In order for a remote operator to rapidly and efficiently control an unmanned vehicle (UV), the operator must be able t

The development of mathematical models for determining antagonism, synergy or additivism for drug combinations is becoming increasingly important in medical research and medicine. This paper describes improvements in the Chou and Talalay method which

The effect of atmospheric turbulence on heterodyne lidar performance is studied by use of scattering theory. A theoretical analysis is carried out for both bistatic and monostatic lidar systems with independently variable transmitter and receiver par

The joint effect of non-Kolmogorov stratospheric and Kolmogorov tropospheric turbulence on star image motion is studied, and the theoretical predictions are compared with measured data. It is shown that for a large telescope the stratospheric effect

A method is presented for sensing atmospheric wave-front tilt from a laser guide star (LGS) by observing a laser beacon with auxiliary telescopes. The analysis is performed with a LGS scatter model and Zernike polynomial expansion of wave-front disto

We have experimentally validated the concept of a differential image motion (DIM) lidar for measuring vertical profiles of the refractive-index structure characteristic C(n)(2) by building a hard-target analog of the DIM lidar and testing it against

A concept of a Hybrid Wavefront-based Stochastic Parallel Gradient Decent (WSPGD) Adaptive Optics (AO) system for correcting the combined effects of Beacon Anisoplanatism and Thermal Blooming is introduced. This system integrates a conventional phase

For a non-cooperative target, a laser beacon is created by illuminating the target with a beacon beam. When a beacon beam propagates though deep turbulence, turbulence spreads the beam. A conventional phase conjugate adaptive optics (AO) system is no
