EFFICIENCY AND CURRENT REVERSALS IN SPATIALLY INHOMOGENEOUS RATCHETS [PDF]

International Journal of Modern Physics B, 2000
Efficiency of generation of net unidirectional current in an adiabatically driven symmetric periodic potential system is studied. The efficiency shows a maximum, in the case of an inhomogeneous system with spatially varying periodic friction coefficient, as a function of temperature. The ratchet is not most efficient when it gives maximum current. The

Methods to Determine the Current Efficiency in AC Electrolysis [PDF]

Arabian Journal for Science and Engineering, 2020
AbstractThe paper presents several methods (analytical, electromechanical and electronic) for determining the cathodic current efficiency of the metal deposition processes carried out by AC or pulse current. Based on the results of own experimental researches (for indium, cadmium, nickel, tin and zinc), the appropriate equations are given and the ...

Prediction of Physical and Mechanical Properties of Al₂O₃–TiB₂–TiC Composites Using Design of Mixture Experiments

Ceramics
In this study, the design of mixture experiments was used to find empirical models that could predict, for a first approximation, the relative density, flexural strength, Vickers hardness and fracture toughness of sintered composites in order to identify

Progress on efficient current‐induced magnetization switching [PDF]

Electrical Engineering in Japan, 2020
AbstractAs efficient current‐induced magnetization switching schemes, thermally assisted spin transfer torque (STT) switching, spin orbit torque (SOT) switching of rare‐earth transition metal films, and electric‐field–assisted SOT switching were briefly reviewed. For thermally assisted STT switching, hybrid memory layer with a low curie temperature (TC)

An Efficient Algorithm for Current Source Localization with Tetrodes [PDF]

2007 29th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2007
In this article we develop a simple algorithm for localization of electrical sources in neurons. The algorithm is based on multiple measurements of neuron's action potentials acquired from multiple sensors, such as tetrodes. We show that in many cases this problem can be solved analytically.
