Heat release in a gas flow at the junction of channels with different surface roughnesses

A measurement is made of the thermal polarization which develops in a gas flow in a nonuniform channel due to the dependence of the mechano-caloric heat flux on surface roughness.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 59, No. 3, pp. 466–470, September, 1990.     

Dynamics of a nonlinear oscillator under quasi-periodic drive action

The dynamics of a nonlinear oscillator under quasi-periodic drive action is studied using the model of an excitable electric circuit with a nonlinear diode. In the space (plane) of control parameters, the system dynamics is described by the torus doubling lines and the lines of transition to a strange nonchaotic attractor, which connect the so-called torus doubling terminal points. The transition to chaos in this system proceeds either via the formation of a strange nonchaotic attractor or via a torus-to-chaos intermittency regime.

Linear chains of Ge/Si quantum dots grown on a prepatterned surface formed by ion irradiation

Semiconductors - The growth of Ge nanoclusters on a prepatterned Si (100) surface formed by imprint lithography in combination with subsequent irradiation with Ge+ ions is studied. The prepatterned...
