The transmission of pictures by pulse code modulation (PCM) has been investigated by various researchers1, 2 for more than a decade. Recently, interest has reached a new high, partly because of the possible military and space applications. The purpose of the present article is to describe briefly some of the research work being carried on in Pcm ...

This chapter introduces to the basic definitions of the PCM model for a molecular solute. The basic electrostatic problem for the determination of the solute-solvent interaction is described within the Integral Equation Formalism (IEF-PCM), and the QM problem associated to the effective Hamiltonian of the molecular solute is formulated in terms of a ...

Heat storage is a subject of considerable importance in power engineering. The most common methods of heat storage exploit the thermal capacity, the latent heat, the heat of reaction and of photo chemical reaction and production of fuels. This work is concentrated on heat storage by exploiting the phenomenon of solidification as a special case of ...

Logarithmic non-uniform quantisation that delivers a constant signal-to-quantisation noise ratio (SQNR) across all input signal levels. The benefit and price of non-uniform quantisation are also quantified in terms of companding gain and companding penalty.A comprehensive treatment of A-law and m-law PCM source coding standards, including derivation of

This chapter presents the common design challenges of using PCMs. Issues with containment in the melt phase are discussed, with several different possible solutions presented. These include simple box containment, flexible films, shape-stabilization and microencapsulation.
