Erosion Potential Method (Gavrilović method) sensitivity analysis

Estimating of erosion and sediment yield of Gorganrud basin using erosin potential method

Soil erosion can be considered as one of the most important obstacles in the way of sustainable development of agriculture and natural resources. The aim of this study is to estimate erosion and sediment yield of basin using Erosion Potential Method, in Gorganrud basin, north of Iran. The main factors in the EPM (slope average percent, erosion, rock and soil resistance, and land-use) were evalu...

A Sensitivity-Analysis Method for Inverse Simulation

Method for sensitivity analysis of photonic crystal

We present a new method for sensitivity analysis of photonic crystal devices. The algorithm is based on a finite-difference frequency-domain model and uses the adjoint variable method and perturbation theory techniques. We show that our method is highly efficient and accurate and can be applied to calculation of the sensitivity of transmission parameters of resonant nanophotonic devices. © 2004...

An ESDIRK method with sensitivity analysis capabilities

A new algorithm for numerical sensitivity analysis of ordinary differential equations (ODEs) is presented. The underlying ODE solver belongs to the Runge–Kutta family. The algorithm calculates sensitivities with respect to problem parameters and initial conditions, exploiting the special structure of the sensitivity equations. A key feature is the reuse of information already computed for the s...

The Ford Method: A Sensitivity Analysis Approach

In dynamic models, a system behavior is determined by the interaction of its feedback loops. The challenge for system dynamics modellers is to identify these loops, and also understand, over the runtime of a model, which loops dominate system behavior. The Ford method is a procedure that identifies changes in atomic behavior patterns in the presence, and absence, of feedback loops, in order to ...
