ENERGOAGREGAT WITHOUT EXTERNAL ROTATING ELEMENTS

Performance of Rotating Solar Still with Rotating External Reflectors (RESEARCH NOTE)

In this research, a rotating solar still that uses external bottom reflectors was experimentally investigated. The solar still and reflectors have the capability to shift their angle with respect to the south and the reflectors have the capability to shift their angle with respect to the horizon. The experiment has been performed in both fixed and rotating states. For the fixed state the solar ...

Vibrational Superposition States Without Rotating Wave Approximation

We propose a scheme to generate superpositions of coherent states for the vibrational motion of a laser cooled trapped-ion. It is based on the interaction with a standing wave making use of the counter-rotating terms, i.e. not applying the rotating wave approximation. We also show that the same scheme can be exploited for quantum state measurement, i.e. with the same scheme non-classical states...

Estimating Location without External Cues

The ability to determine one's location is fundamental to spatial navigation. Here, it is shown that localization is theoretically possible without the use of external cues, and without knowledge of initial position or orientation. With only error-prone self-motion estimates as input, a fully disoriented agent can, in principle, determine its location in familiar spaces with 1-fold rotational s...

Market Crashes without External Shocks

Market crash is usually considered an indication that the fundamentals of the economy have changed and recession is around the corner. This, however, need not be the case. For instance, in October 1987 Wall Street lost over 20% of its value in one day, but this was not followed by a recession. Moreover, in the days preceding the crash, there were no significant external events or “bad news” tha...
