Computational Approaches to Complexity in Geophysics

科学中的复杂性产生于特定的问题， 不能作为孤立的系统进行卓有成效的研究， 独立于其他人。 这些问题往往是 有利地使用计算机模拟进行研究，但前提是 用于正确地对子系统的交互进行建模的方法可以 被设计。 该项目涉及计算方法， 物理学中表现出复杂性的各种问题。 具体应用是在流体动力学的一般领域 （两相流和多孔介质中的流动）和非线性地震 反演 在每一个问题中， 组成部分的相互依赖性可以通过以下方式来克服： 产生复杂性的基本计算机算法的设计 在保持简单性的同时， 在微观的，组件的水平上。

Complexity in science arises in particular problems that may not be fruitfully studied as isolated systems acting independently of others. Often these problems are instead advantageously studied using computer simulation, but only if a method for correctly modeling the interactions of subsystems can be devised. This project involves computational approaches to a variety of problems that exhibit complexity in geophysics. Specific applications are in the general areas of fluid dynamics (two-phase flow and flow in porous media) and nonlinear seismic inversion. In each of these problems, the seemingly intractable interdependence of component parts may be surmounted by the design of elementary computer algorithms that produce complexity in macroscopic, aggregate behavior while maintaining simplicity at the microscopic, component level.
