The technique of using nonlinear approximations to design controllers for chaotic dynamical systems introduced by Yagasaki and Uozumi is extended in order to enable it to be used to design controllers for chaotic dynamical systems that are described by implicit maps and is then used to control the well-known bouncing ball system without recourse to the high-bounce approximation.

We present engineering airflow to intercept the transmission of Covid19 in public spaces and transportations, which relatively fast simple. This technique is suppress effectively as massive possible spread aerosols droplets contaminated with COVID-19 virus that flying air by providing a vertical downward flow using fans placed on ceilings use floors certain material so aerosol microdroplets wil...

Introduction A bidirectional sampling method with raybundles [TO12] enables high-quality global illumination, but computation time of ray-bundles depends on the number of sample directions and the number of primitives. This poster proposes an approximate ray-bundle tracing based on imperfect shadow maps (ISMs) [RGK∗08]. ISMs accelerate light path visibility tests using a point-based rendering. ...

Light pulses entering an elongated bottle microresonator (BMR) from a transversely oriented input–output waveguide (microfiber) slowly propagate along the BMR length and bounce between turning points at its constricting edges. To avoid insertion losses processing errors, pulse should completely transfer into and, after being processed, return back waveguide. For this purpose, be impedance match...

In the ekpyrotic scenario the Universe is initially collapsing, the energy density coming from a scalar field with a negative exponential potential. On the basis of a calculation ignoring the gravitational back-reaction the authors of the scenario claim that during collapse the vacuum fluctuation creates a perturbation in the comoving curvature, which has a flat spectrum in accordance with obse...

Experimental and theoretical studies are made of a typical snap-action rocker switch, to establish the wear mechanisms in the pivoting contact. The rocker switch, used extensive~ in consumer goods, operates in the medium duty current range, (1 30 Amps). Highspeed photographic studies have shown that the main cause of wear is arcing, occurri~ during separation and bounce at the pivot contacts. T...
