The Use of Synthetic Lubricants in Compressors

Some aspects of aerodynamic flow control using synthetic-jet actuation.

Aerodynamic flow control effected by interactions of surface-mounted synthetic (zero net mass flux) jet actuators with a local cross flow is reviewed. These jets are formed by the advection and interactions of trains of discrete vortical structures that are formed entirely from the fluid of the embedding flow system, and thus transfer momentum to the cross flow without net mass injection across...

Some aspects of cosheaves on diffeological spaces

We define a notion of cosheaves on diffeological spaces by cosheaves on the site of plots. This provides a framework to describe diffeological objects such as internal tangent bundles, the Poincar'{e} groupoids, and furthermore, homology theories such as cubic homology in diffeology by the language of cosheaves. We show that every cosheaf on a diffeological space induces a cosheaf in terms of t...

Some Aspects on Adiabatic Switching

In adiabatic switching 2] up to now the major focus has been on proving the usefulness of this kind of circuit technology by constructing various kinds of digital systems in full custom design. This is, however, not a desirable way to treat more complex systems. Therefore, it is necessary to provide some systematic design procedure that can be automized and is capable to handle all kinds of log...
