A Stepwise Fitting Procedure for automated fitting of Ecopath with Ecosim models

A Semi-Automated Map Fitting Procedure

The electron density applications available within QUANTA96 represent novel and effective tools for speeding up the processes of Cα tracing experimental maps and manual rebuilding during refinement. The various modules (XAUTOFIT, X-BUILD, X-SOLVATE and XLIGAND), have been developed over the past year in close collaboration with the large number of crystallographers working on projects in the Pr...

Ecopath with Ecosim: a User’s Guide

Ecopath with Ecosim: methods, capabilities and limitations

TheEcopathwithEcosim (EwE)modeling approach combines software for ecosystem trophicmass balance analysis (Ecopath), with a dynamic modeling capability (Ecosim) for exploring past and future impacts of fishing and environmental disturbances as well as for exploring optimal fishing policies. Ecosim models can be replicated over a spatial map grid (Ecospace) to allow exploration of policies such a...

Automated Parameter Fitting for Compartmental Models

Several factors have caused an increase in the demand for methods that are able to automatically fit the parameters of neuron models. More and more computing power becomes available to neuroscientists so is less difficult to extensively explore the fitness landscape created by, for example, varying the densities or kinetics of the ion channels in a neuron model. Because of the detail used in so...

Propagation Models and Fitting Them for the Boolean Random Sets

In order to study the relationship between random Boolean sets and some explanatory variables, this paper introduces a Propagation model. This model can be applied when corresponding Poisson process of the Boolean model is related to explanatory variables and the random grains are not affected by these variables. An approximation for the likelihood is used to find pseudo-maximum likelihood esti...
