IntroductIon Nowadays, data management on the World Wide Web needs to consider very large knowledge databases (KDB). The larger is a KDB, the smaller the possibility of being consistent. Consistency in checking algorithms and systems fails to analyse very large KDBs, and so many have to work every day with inconsistent information. Database revision—transformation of the KDB into another, consi...
متن کاملThe Thomson Effect and the Ideal Equation on Thermoelectric Coolers
The formulation of the classical basic equations for a thermoelectric cooler from the Thomson relations to the non-linear differential equation with Onsager’s reciprocal relations was performed to basically study the Thomson effect in conjunction with the ideal equation. The ideal equation is obtained when the Thomson coefficient is assumed to be zero. The exact solutions derived for a commerci...
متن کاملImproved Thermoelectric Cooling Based on the Thomson Effect
Traditional thermoelectric cooling relies on the Peltier effect which produces a temperature drop limited by the figure of merit, zT. This cooling limit is not required from classical thermodynamics but can be traced to problems of thermoelectric compatibility. Alternatively, if a thermoelectric cooler can be designed to achieve full thermoelectric compatibility, lower temperature can be achiev...
متن کاملThe Thomson Effect and Thermal Conduction in Metals.
The Thomson Eflect.-In these PROCZZDINGS for March, 1920, is a paper in which I undertook to account for the Thomson effect values, as found by Bridgman for many metals, in accordance with the hypothesis of dual electric conduction. Using data obtained by the methods of that paper, I was able. as I stated at the Washington meeting of the National Academy in April, 1920, to account quantitativel...
