Numerical algorithm of the solution of the multiphase Stefan problem

A method is proposed for computing the temperature and position of the phase interface based on the passage to new variables and a new function. The transformation is invariant relative to the heat-conduction equation, and the boundaries in the new variables are fixed.Notation t time - z coordinate - T(z, t) temperature - (z, t),a(z, t) coefficients of thermal conductivity and thermal diffusivity, respectively - h_m(t) coordinates of the phase-interface position - H lower boundary coordinate - L heat of the phase transition - volume weight of the soil - w⁰(z) given moisture distribution in the soil - w₀ experimentally determined quality of moisture which does not freeze at 0°C Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 31, No. 5, pp. 876–882, November, 1976.     

The Noosphere Paradigm of the Development of Science and Artificial Intelligence

The disciplinary, transdisciplinary, and noosphere paradigms of the development of science and a natural-scientific picture of the World are considered. The role of science, its information-technological component, and the role of artificial intelligence in the evolution of the modern society and noospheregenesis as a whole are described. The basic concepts of the modern paradigm of science are substantiated and formulated. Their essence lies in the efficient combination of problems of knowledge of Nature and society evolution within the framework of the transdisciplinary paradigm.     

Transdisciplinarity Problems and the Role of Informatics

Some methods and tools of information-technological support of transdisciplinary scientific investigations are proposed and reviewed during their formation and development. Emphasis is placed on ontology-driven service-oriented systems of knowledge representation in a global network environment.

Method of testing gear wheels in impact bending

Chemicothermal treatment processes are widely used in engineering to improve the working lives of important components, of which the most common is nitrocementation. That process has been applied at the Volga Automobile Plant mainly to sprockets in gear transmissions, which need high hardness and wear resistance in the surfaces with relatively ductile cores. Although various forms of chemicothermal treatment are widely used, there has been no universal method of evaluating the strengths of gear wheels. Standard methods of estimating strength (_u, _t, _b, and hardness) have a major shortcoming: They can determine only the characteristics of the cores for case-hardened materials. Here we consider a method of impact bending test, which enables one to evaluate the actual strength of gear teeth.Paper presented at the Second Russian Metallographers' Convention.Volga Automobile Plant.
