This study is about the non-uniform electric field for splitting of water in oil emulsion. If the process occurs in an inhomogeneous electrical field, the drops are polarized and then their mobility is increased. The emulsion drops will be charged and move toward the central point of splitter where the maximum intensity of electrical field has been concentrated. In this process, the drops encou...

Impact is implicated in the development of several types of musculoskeletal injury in the horse. Characterisation of impact experienced during strenuous exercise is an important first step towards understanding the mechanism for injury. Measurement and analysis of large, short duration impacts is difficult. The measurement system must be able to record transient peaks and high frequencies accur...

Sensitivity of neurons in the torus semicircularis of a weakly electric fish, Gymnarchus niloticus, to two stimulus parameters that are critical for its behavior the jamming avoidance response was examined. The first parameter is the sign of frequency difference between discharge frequencies of fish's own electric organ and that of a neighbor's. The second parameter is the spatial orientation o...

In this study, we propose a new concept for touch sensors based on the measurement of current generated by electrostatic induction. The proposed sensor can detect the timing of contact between two objects under perfect noncontact condition. When a human body comes in contact with an object, electrostatic charge is generated in the human body due to the tribological interaction. We assume that t...

This paper reviews published literature and current problems relating to the assessment of occupational and residential human exposures to power-frequency electric and magnetic fields. Available occupational exposure data suggest that the class of job titles known as electrical workers may be an effective surrogate for time-weighted-average (TWA) magnetic-field (but not electric-field) exposure...

The amplitude and the transient time constant of the acoustoelectric voltage is measured as a function of temperature to determine the activation energy of deep levels in AI,Ga, -.As/GaAs grown by molecular-beam epitaxy. In comparison to other methods based on monitoring the capacitance transient, this method has several advantages. The technique is nondestructive, and because of the dependence...

Three kinds of research are pursued in the molecular beam laboratory: 1. High-precision studies of atomic and molecular hyperfine structure, an example being the recent discovery and measurement of an octopole interaction in the bromine atom. 2. The development of atomic frequency standards by using atomic and molecularbeam techniques. The carbon monoxide electric resonance studies and the ammo...

Use of electric vehicles (EVs) has been viewed by many as a way to significantly reduce US oil dependence, operate vehicles more efficiently, and reduce carbon emissions. Due to the potential benefits of EVs, the federal and local governments have allocated considerable funding and taken a number of legislative and regulatory steps to promote EV deployment and adoption. With this momentum, it i...

Using the numerical solution to the time-dependent Dirac equation we show that the effect of relativity on the usual Larmor period for an electron in a magnetic field can be enhanced drastically if a suitably scaled and aligned static electric field is added to the interaction. This electric field does not change the electron’s speed but leads to an elliptical spin precession due to relativity....
