Like all magazines, we retouch images removing wrinkles in fabric, stray hairs, a few zits, random bra straps but we never alter the way the girls on our pages really look. It crucial that we represent girls of all shapes, sizes, and skin tones for their real beauty. Our Body Peace Project is one of the cornerstones of our mission: We want every girl to stop obsessing about what her body looks like and start appreciating it for what it can do! While we work hard behind the scenes to make sure we being authentic, your notes made me realize that ....etc

Output relay Back-EMF Protection



Description

When an electric lock is de-energised, the collapsing magnetic field produces energy to be
generated within the windings of the coil. This energy produces a voltage (or EMF) within the
coil, of the opposite polarity to the normally applied voltage used to energise the magnet.
This ‘back-EMF’ can result in hundreds of volts and can cause damage to the switching relay,
as it sparks across the contacts.
It is normal practice to install a diode, or bridge ....etc

Electrical impedance tomography (EIT) is a medical imaging technique in which an image of the conductivity or permittivity of part of the body is inferred from surface electrical measurements. Typically, conducting electrodes are attached to the skin of the subject and small alternating currents are applied to some or all of the electrodes. The resulting electrical potentials are measured, and the process may be repeated for numerous different configurations of applied current.

Proposed applications include monitoring of lung function, dete ....etc

To begin with, the word tomography can be explained with reference to ?tomo? and
?graphy?; ?tomo? originates from the Greek word ?tomos? which means section or slice,
and ?graphy? refers to representation. Hence tomography refers to any method which
involves reconstruction of the internal structural information within an object mathematically from a series of projections.

The projection here is the visual information probed using an emanation which are physical processes involved. These include physical processes such as radiation, wa ....etc

Abstract
A non-destructive estimation of the state-of-charge _SoC. of batteries facilitates optimum utilization of the battery for a given application, as well as evaluation of its state-of-health. Among various methods, a.c. impedance spectroscopy over a wide range of frequencies provides a variety of parameters which are functions of the SoC of a given battery. These parameters and their variation with SoC depend on the type of battery and on the experimental conditions. The impedance data of sealed commercial cells are rather tedious to a ....etc
