ABOUT FEATURES OF BOUNDARY LAYER IN DENSE GAS

In given article the task about laminar boundare layer on heat-insulated plate is considered. The numerical solution of task in view of real dependence of factors from density and temperature is adduced.

OUTPUT POWER DYNAMICS OF LASER DIODE WITH NONLINEAR DELAYED FEEDBACK

An experimental results of investigating a chaotic system which consists of a single mode tunable laser diode, low fines Fabry-Perot interferometer and delayed electrical feedback loop are presented. It is shown that the increasing of gain coefficient in feedback loop lead to strong changes in system behavior - a chaotic state of output power through period - doubling bifurcation evolve from a single stationary state.
