MATHEMATICAL MODEL ANALYSIS OF OPEC PRICING POLICY IMPACTS ON LONG-RANGE ENERGY SUPPLIES
Proceedings of SPE Hydrocarbon Economics and Evaluation Symposium, 1979Abstract This paper outlines the nature and scope of a linear-programming model system (LORENDAS) designed for quantitative analysis of world-wide Long-range Energy Developments and Supplies. Basic projections, to the year 1996, of U.S.

Mathematical modeling of angular distortions in laser ranging of the RadioAstron satellite
Computational Mathematics and Mathematical Physics, 2008Summary: A mathematical model for angular distortions in satellite laser ranging is constructed with allowance for effects of the theory of general relativity. For the RadioAstron mission satellite, it is shown that the angular distortions exceed the present-day accuracy of angular measurements in satellite laser ranging at all orbit points. Manifested

Mathematical Modeling of Refractive Properties of the Atmosphere in the Optical Wavelength Range
2020 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (EIConRus), 2020The article describes an approach to mathematical modeling that allows one to calculate the refractive index of the atmosphere and indirectly evaluate the refractive properties of the atmosphere. The initial parameters are numerical values of atmospheric pressure, temperature, and air humidity.

Mathematical and computational modeling of nano-engineered drug delivery systems.
Journal of Controlled Release, 2019While the advent of nano-engineered drug delivery systems (DDSs) has revived hopes for better management of a wide range of pathologies, critical appraisal of the field has shown that further improvement of nanomedicine demands a paradigmatic shift in ...

Development and application range of mathematical models for 3-way catalytic converters
Applied Catalysis B: Environmental, 1997Abstract The need for reliable 3-way catalytic converter modeling in the design of demanding exhaust systems for low-emitting vehicles has been widely recognised. Although a number of related models have been presented in the literature, the efficient performance in actual 3-way applications requires further development and validation.

A mathematical model of TIG electric arcs operating in the hyperbaric range
Journal of Physics D: Applied Physics, 1996In a recent paper Ducharme et al presented a model for a free-burning tungsten inert gas (TIG) electric arc with non-consumable electrodes using a flat anode and argon shielding gas. The model evaluates the laminar gas flow, temperature distribution and electric field in the arc column by treating the current carrying region of the arc as a partially ...

Mathematical modeling and simulation of the input signals of short-range radar systems
Journal of Communications Technology and Electronics, 2014Problems of the mathematical modeling and simulation of the input signals of short-range radar systems (SRRSs) arriving from objects with a complex geometric shape are considered. It is shown that, in the quasi-optical radio band, application of the method of physical theory of diffraction to polygonal description of the object’s spatial configuration ...

Mathematical Models for Studying the Long-Range Transport of Air Pollutants
1995The long-range transport of air pollutants, the LRTAP, is a very complicated physical phenomenon. Some air pollutants can be transported over long distances to remote areas that are far away from the big emission sources. Moreover, under certain circumstances the transported air pollutants may lead (directly or indirectly) to some damaging effects on ...
