mathematical computation
1.Coastal and estuarine engineering,layout and planning of harbours and navigation channels;river training,siltation prediction and its measures;mathematical model computation and physical model experiments.
4.2. Establishing the mathematical model of aerodynamic computation by using engineering prediction method, especially the accessional drag model of inlet;
5.A transient, three-dimensional, non-isothermal and two-phase mathematical model based on computation fluid dynamics was developed to describe the dynamic process of PEMFC.
6.Effect algebras were introduced as a mathematical model of quantum computation by American mathematicians Foulis and Bennett in 1994, which generalized orthomodular lattices.
7.This paper applies the characters of primes in the mathematical theory of numbers,transfers the symbolic computation into value computation,and designs a tool of Boolean expression simplification.
8.This topic main technology is the Bezier curve analysis, the design, the computation and the production, prototype production system mathematical model is containing Bezier curve splicing, the interpolation computation and so on the essential knowledge, the clothing prototype by the straight line and curve splicing, calculates composes.
9.When getting some low order semi-invariant withbasic theory of Probability Theory & Mathematical Statistics, we can enough preciselyestimate the PDF and CDF of the load flow by the Gram-Charlier expanding. Thus itsignificantly reduces computation effort and the computation storage space.
10.Based on the column experiment of transportation of TCE and PCE, and on the hydrogeochemical properties of groundwater in the study area, we set up a mathematical model of transportation and transformation of TCE and PCE with biodegradation, with the fate of TCE, PCE being simulated on computer. The coincidence of computation results with measured values shows that the mathematical model is reasonable, and that biodegradation does exist in study area. Through this study, the scientific basis for subsequent treatment of organic contaminants are well-established.
