The lifetimes of coasting beams in LEP are computed from the difference of the bunch currents measured during a time interval of a few seconds. The quality of these measurements is presently limited by the noise figure of the bunch to bunch aquistion system. This paper decribes comparative studies on the aquistion system in order to improve the noise figure by one order of magnitude. For this p...

By synergistically combining modeling, simulation and experiments, we show that there exists a regime of self-propulsion in which the inertia fluid dynamics can be separated from swimmer. This is demonstrated by motion an asymmetric dumbbell that, despite deforming reciprocal fashion, self-propagates due to non-reciprocal Stokesian flow field. The latter arises difference coasting times two con...

Several optimal three-dimensional orbital transfer problems are solved for thrust-limited spacecrafts using collocation and nonlinear programming techniques. The solutions for full nonlinear equations of motion are obtained where the integrals of the free Keplerian motion in three dimensions are utilized for coasting arcs. In order to limit the solution space, interior-point constraints are use...

Ladars provide a unique capability for identification of objects and motions in scenes with fixed 3D field of view (FOV). This paper describes algorithms for multi-target tracking in 3D scenes including the preprocessing (mathematical morphology and Parzen windows), labeling of connected components, sorting of targets by selectable attributes (size, length of track, velocity), and handling of t...

Affective dynamics are discussed from the perspective of a view of origin and functions of affective valence based in control processes. This view posits that affect reflects the error signal of a feedback loop managing rate of progress at goal attainment or threat avoidance. Negative feelings signal doing poorly, demanding more effort. Positive feelings signal doing better than necessary, allo...

Implosions of spherical and cone-in-shell targets in direct-drive inertial confinement fusion (ICF) are studied with proton radiography. Time-gated, 15-MeV proton images provide a unique and comprehensive picture of ICF implosions that cover all the implosion phases from acceleration, through coasting, deceleration, to stagnation. Observation and study have resulted in the discovery and charact...
