[8] [9] A cinematographic study in 1970 established that the phase-change-memory mechanism in chalcogenide glass involves electric-field-induced crystalline filament growth. [ 10 ] [ 11 ] In the September 1970 issue of Electronics , Gordon Moore , co-founder of Intel , published an article on the technology. [ 12 ]
Additionally, because it is a solid/solid phase change, there is no visible change in the appearance of the PCM, and there are no problems associated with handling liquids, e.g. containment, potential leakage, etc. Currently the temperature range of solid-solid PCM solutions spans from -50 °C (-58 °F) up to +175 °C (347 °F).

Computational Fluid Dynamics (CFD) modeling and simulation for phase change materials (PCMs) is a technique used to analyze the performance and behavior of PCMs. The CFD models have been successful in studying and analyzing the air quality, natural ventilation and stratified ventilation, air flow initiated by buoyancy forces and temperature space for the systems integrated with PCMs.
General structure of arylcyclohexylamines. An arylcyclohexylamine is composed of a cyclohexylamine unit with an aryl moiety attachment. The aryl group is positioned geminal to the amine.
Pulse-code modulation (PCM) is a method used to digitally represent analog signals.It is the standard form of digital audio in computers, compact discs, digital telephony and other digital audio applications.
A 2008 United States military market survey for a Precision Sniper Rifle (PSR) called for 1 minute of arc (0.3 milliradian) extreme vertical spread for all shots in a 5-round group fired at targets at 300, 600, 900, 1,200 and 1,500 meters.

Some people argue that PCM is a synonym for target costing. [1] [2] [3] However, others argue that PCM is different, because target costing is a pricing method, whereas, PCM is focused on the maximum profit or minimum cost of a product, regardless of the price at which the product is sold to the end customer.
