Statements by the Ecological Society of America on the proposed U.S. exit from the Paris Agreement, and on Climate Change

Posted on 15 June 2017 by ecoquant

By withdrawing from the Paris Agreement on climate change, the United States is abdicating its role as the world leader in using science-based information to inform policy. Business, political, and scientific leaders the world over are condemning the decision. More … Continue reading →

Repaired R code for Markov spatial simulation of hurricane tracks from historical trajectories

Posted on 11 August 2016 by ecoquant

(Slight update, 28th June 2020.) I’m currently studying random walk and diffusion processes and their connections with random fields. I’m interested in this because at the core of dynamic linear models, Kalman filters, and state-space methods there is a random … Continue reading →

A model of an electrical grid: A vision

Posted on 3 August 2016 by ecoquant

Many people seem to view the electrical grid of the future being much like the present one. I think a lot about networks, because of my job. And I especially think a lot about network topologies, although primarily concerning the … Continue reading →
