Abstract: Apparatus and method for hashing a message, comprises using an array of individually selectable memristor cells. The memristor cells are subject to write disturb that affects cells neighboring a selected cell so that a write operation into one cell has a knock-on effect on the neighbors. The array is initiated into a known stable state so that these changes to neighboring cells are predictable according to proximity to the currently selected cell. An inserter sequentially mixes bits with the hash so far to insert bits into successively selected cells of the memristor array and forms a succession of memristor array states including the knock on effects on the neighboring cells. A final resulting memristor array state following input of the bits forms the hash of the message.

Abstract: According to an aspect of some embodiments of the present invention there is provided a method for converting energy. The method comprises receiving energy from an external source, using the received energy for inducing a mass exchange process to release thermodynamic energy, and converting the thermodynamic energy directly into electrical energy at sufficient amount for performing work therewith. In some embodiments of the present invention, a portion of the released energy is converted to a pressure wave, and the mechanical energy constituted by the pressure wave is converted to non-mechanical energy.

Abstract: New exemplary heat exchange configurations that incorporate internal or external surfaces equipped with perturbators, for changing the thermal behavior of the system, or for modulating the surface temperature distribution of the flow surfaces. This is achieved by applying an acoustic wave to the fluid flow in a heat exchange passage, and selecting the frequency of the acoustic exciting wave to be the same as the acoustic resonance frequency of the heat exchange passage itself. As the traveling waves interact with the boundaries confining the heat exchange passages, constructive interference of the incident and reflected waves give rise to a standing wave. Thus, the heat exchange passages act as a resonator, and by superimposing this standing wave on the separating and reattaching fluid flow, significant heat transfer improvement can be achieved. This is accomplished without the need to significantly increase the pressure required to achieve the desired through flow.
