Thermodynamics of copper matte converting: Part III. Steady-state volatilization of Au,Ag, Pb,Zn, Ni,Se, Te,Bi, Sb,and As from slag,matte, and metallic copper

A comprehensive compilation of various thermodynamic data required for a complete analysis of copper matte converting reactions is presented. The data comprise estimated free energies of formation for such gases as SeO, SeS, TeO, TeS, BiO, BiS, SbO, SbS, AsO, and AsS, as well as activity coefficients in dilute copper alloys and vapor pressures of various elements and compounds. The volatilization of minor elements in steady-state reactors comprising gas and several condensed phases is mathematically formulated, and a parameter which governs the volatilization in such reactors is defined and named volatilization constant. The vapor pressures of various volatile species are calculated thermodynamically for the Noranda Process reactor by assuming equilibrium conditions. The volatilization constants of various minor elements are expressed explicitly as functions of oxygen and sulfur activities.

Kinetics of local probe oxidation of ultrathin V,Nb, Ta,Ti, TiN,and W metal films

The specific features of the kinetics of local probe oxidation of ultrathin V, Nb, Ta, Ti, TiN, and W metal films are studied. It is established that the kinetics of the oxidation process depends on such properties of the material to be oxidized as the resistivity, the presence of a natural surface oxide film and its thickness, the relationship between the densities of the metal and oxide, and the electrochemical constant of the oxidation process. For the material that provides a high efficiency of formation of local insulator nanoregions, vanadium is chosen, since this metal exhibits the maximum rate of anodic probe oxidation.     

A function of time, frequency, lag, and Doppler

In signal processing, four functions of one variable are commonly used. They are the signal in time, the spectrum, the auto-correlation function of the signal, and the auto-correlation function of the spectrum. The variables of these functions are denoted, respectively, as time, frequency, lag, and Doppler. In time-frequency analysis, these functions of one variable are extended to quadratic functions of two variables. In this paper, we investigate a method for creating quartic functions of three of these variables as well as a quartic function of all four variables. These quartic functions provide a meaningful representation of the signal that goes beyond the well-known quadratic functions. The quartic functions are applied to the design of signal-adaptive kernels for the Cohen class and shown to provide improvements over previous methods     

Thermodynamics of copper matte converting: Part IV.A priori predictions of the behavior of Au,Ag, Pb,Zn, Ni,Se, Te,Bi, Sb,and As in the Noranda Process reactor

The general formulae are derived which allow calculation of the weight of each molten phase (copper, matte, slag) in the Noranda Process reactor as a function of matte grade and suspension indices. These expressions and the volatilization constants are then inserted in the steady-state volatilization equation (derived in the Part III) to calculate the overall distribution of minor elements and their concentrations in all the reactor products(i.e., copper, matte, slag, and offgas) in the Noranda Process. The overall distribution of ten minor elements can be predicted for any set of controllable process parameters such as feed composition, temperature, degree of oxygen enrichment, slag composition (or magnetite activity), and matte grade. The computer predictions are in good agreement with the commercially observed values with the exception of selenium.

Competition in high technology: analysis of patents of US, Japan,UK, France, West Germany, and Canada

Using US patents as a surrogate measure of technological positions, the competitive positions of the industrial nations (the US, United Kingdom, France, West Germany, Canada, and Japan) in high-technology areas during the period from 1975 to 1988 are examined. High-technology industry is defined as one which requires a high proportion of R&D expenditure and employs a high proportion of scientists and engineers. High-tech industries are further subdivided into four categories (equipment, consumer durable, nondurable, and intermediate products) in terms of their market and/or use. How different countries have specialized in different product market areas within the high tech sector is also examined. To better understand the impact of the patients, the citations per patent for the different countries and the citation performance ratio, which is the share of country's most highly cited patents on a worldwide basis, are examined     

The state of the art of electrostatic discharge protection:physics, technology, circuits, design, simulation, and scaling

A comparative analysis of network dependability, fault-tolerance, reliability, security, and survivability

A number of qualitative and quantitative terms are used to describe the performance of what has come to be known as information systems, networks or infrastructures. However, some of these terms either have overlapping meanings or contain ambiguities in their definitions presenting problems to those who attempt a rigorous evaluation of the performance of such systems. The phenomenon arises because the wide range of disciplines covered by the term information technology have developed their own distinct terminologies. This paper presents a systematic approach for determining common and complementary characteristics of five widely-used concepts, dependability, fault-tolerance, reliability, security, and survivability. The approach consists of comparing definitions, attributes, and evaluation measures for each of the five concepts and developing corresponding relations. Removing redundancies and clarifying ambiguities will help the mapping of broad user-specified requirements into objective performance parameters for analyzing and designing information infrastructures.
