In larger facilities much of this monitoring work is carried out in real time, with the data transmitted to a remote control station. Increasingly, the corrective actions necessary may take place automatically through a computer modem. 

Parallel bundles of pores (in which all pores of a given size or radius are bound to be equally accessible) are a highly unrealistic structural configuration. Stochastic networks are arrangements of pores into fiilly accessible inter-connected frameworks within which pores are assumed to be distributed randomly. In this way, the size of any pore is taken to be independent of its neighbours. A network may then be constructed to obey any stipulated distribution function by assigning pores from the distribution randomly to positions in the network. Stochastic networks are an attempt to incorporate the elements of randomness and chaos which are implicit to many porous media, in such a way as to retain a feasible computability. Modem computers (and now micro-computers) can readily compute mercury porosimetry into networks comprised of up to millions of pores 11.15).

A useful avalanche diode that works in either direction is the "varistor," sometimes called the "metal oxide varistor," or "MOV." It is not just a single crystal device as the previously described semiconductors are, but instead it is polycrystalline ceramic material, usually zinc oxide, with many small PN junctions at the grain boundaries. It is quite inexpensive and is very rugged, so it can be found as an important part inside most "surge protector power strips" for connecting multiple computer modems, printers, etc., to protect them against inductive kicks and even most "spikes" ("transients") from lightning. ... 

To ensure complete and up-to-date information, the best approach is to use an on-line commercial service. Most mid-sized and larger semieon-ductor companies will already have an account with a commercial service through the company s information center. Alternatively, with a personal computer, modem, and a four to eight hour introductory course, the end user can perform the searches directly. 

Now consider the H FID from ethyl phenylacetate (Fig. 5.15). This complex molecule has many types of hydrogens, and the FID is the superimposition of many different frequencies, each of which could have a different decay rate A mathematical method called a Fourier transform, however, will separate each of the individual components of this signal and convert them to frequencies. The Fourier transform breaks the FID into its separate sine or cosine wave components. This procedure is too complex to be carried out by eye or by hand it requires a computer. Modem pulsed... 

Specifically, Louisiana State University (LSU) is under contract to develop the interface from CAD to CMPP and to develop user-friendly improvements to the software. Auburn Research Center is developing software and methods to provide remote access capability which permits small machine shops to generate a process plan via a Personal computer/modem link to CMPP resident on a main frame, and use the output to automatically generate CNC code for the machine shop s equipment.
