In this report, a detailed description of the physic included in the WHIST/RAZE package as well as a few illustrative examples of the capabilities of the package will be presented. An in depth analysis of ICRF heating experiments using WHIST/RAZE will be discussed in a forthcoming report. A general overview of philosophy behind the structure of the WHIST/RAZE package, a summary of the features of the WHIST code, and a description of the interface to the RAZE subroutines are presented in section 2 of this report. Details of the physics contained in the RAZE code are examined in section 3. Sample results from the package follow in section 4, with concluding remarks and a discussion of possible improvements to the package discussed in section 5.

A simple model of RF heating near the lower hybrid frequency has been added to the BALDUR 1-D tokamak transport code. The code has been used to simulate lower hybrid heating in ATC and PLT. A comparison was made with ATC data, in which the code gave fair agreement. Simulations of PLT were carried out for various input RF power spectra. It was found that the RF waves effectively heated the plasma ions over a certain density range, (2.5 - 3.5 x 1013 cm−3 for proposed experimental parameters), yielding considerably less heating at higher and lower densities. The code predicted a rise in the volume averaged ion temperature of about 1.8 eV per kilowatt of RF input power in the optimum density range.
Cities and Their Vital Systems asks basic questions about the longevity, utility, and nature of urban infrastructures; analyzes how they grow, interact, and change; and asks how, when, and at what cost they should be replaced. Among the topics discussed are problems arising from increasing air travel and airport congestion; the adequacy of water supplies and waste treatment; the impact of new technologies on construction; urban real estate values; and the field of "telematics," the combination of computers and telecommunications that makes money machines and national newspapers possible.
