To illustrate this concept, Fig. 2(c) shows the predicted temperature field given the measurements of the 54 sensors we deployed, and Fig. 2(d) shows the variance in this distribution. We use the conditional entropy of these distributions, H(X s |X A) = − R xs,xA P(x s,x A)logP(x s |x A)dx sdx A to The aim of this Special Issue is to report on recent advances relating to the following themes: (1) non-contact electromagnetic sensors (RF, UHF, near field, electric, magnetic, etc.) used for detecting signals emitted by insulation defects either internally, or external to the equipment in question; (2) practical methods for integrating these   and fall detection using location sensors [3, 9, 10, 11].

This field evaluation has shown that, for a variety of reasons, sensors may fail to detect a release from the primary containment.

In general oxygen deficiencyis caused by the release of inert gases which displace oxygen. Since roughly one fifth of the atmosphere is oxygen, the oxygen concentration is only reduced by a fifth of the inert gas concentration. If e.g. 10 Vol% of helium is released into the atmosphere the oxygen concentration decreases by 2 Vol% while the Often called the invisible killer, carbon monoxide is an odorless, colorless gas created when fuels (such as gasoline, wood, coal, natural gas, propane, oil, and methane) burn incompletely.

In the home, heating and cooking equipment that burn fuel are potential sources of carbon monoxide. Vehicles or generators running in an attached garage can also produce dangerous levels of carbon ://   Conventional sensors detect a physical property directly (A); magnetic sensors detect changes in magnetic fields and from them derive information on physical properties (B).
