The risk of explosion can occur in all activities involving flammable substances which, when mixed with air, form an explosive atmosphere. Explosion protection is intended to prevent the ignition atmospheres. Pressurization, as a type protection, 'p' based on introduction protective gas (air or inert gas) enclosure formation atmosphere within by maintaining overpressure relative surrounding and...

This paper presents an objective speech quality measure which is based on loudness patterns using the equivalent rectangular bandwidth (ERB) scale. The proposed measure, called the loudness pattern distortion (LPD), is computed from the differences between the loudness patterns of the original and processed speech. The LPD measure takes into account the transmission through the outer and middle...

The usage of electronics in outdoor environment is growing therefore the control moisture related failures are becoming more important. main cause these humidity inside which may condense on surfaces or components. To protect from harsh environment, components and encapsulated by using enclosures, however it does not prevent ingress through plastic walls, gaskets, cable feedthroughs etc. Thus, ...
