Nordhaus Nobel recollection

In December 2018 Jesse Ausubel had the privilege and fun of inclusion in the delegation to Stockholm of William Nordhaus for his receipt of a Nobel prize.  The occasion stimulated Jesse’s recollection, “Getting to know Bill Nordhaus and Climate: On the occasion of his receipt of the Nobel Memorial Prize in Economics for the study of the economics of climate change.

Polished version of Michelson Oceans lecture

Jesse Ausubel had the honor in October 2015 to present the Michelson Lecture  at the United States Naval Academy in Annapolis.  Thanks Captain and Professor Emil Petruncio!

We now post a polished version of that lecture, “Ocean Past, Ocean Future: Reflections on the Shift from the 19th to 21st Century Ocean.”

Abstract In the 19th century humans knew little about the oceans, but other forms of life knew a lot. Our job the past 135 years has been to catch up and surpass other forms of life in knowledge of the oceans. The advance of observation through science and technology, including new carriers and processors of information, has vastly expanded the oceans knowable to humans beyond what a sailor’s five senses could directly provide. By infiltrating the ocean with informationally connected sensors, humans are becoming the top experts on the oceans in the 21st century.

Loglet Lab software version 4

The behavior of a dynamic system, be it biological or socio-technical, frequently resembles a series of logistic wavelets, or “loglets.” Loglet analysis involves the decomposition of growth and diffusion patterns into S-shaped logistic components.  In the easiest cases, a loglet appears as a single S-shaped curve.  LogletLab is designed for use with user data to help users analyze and decompose growth processes.

LogletLab software has gone through several development cycles since the initial release of LogletLab 1 in 1998 straight through to the recent release of LogletLab 4.1, an online tool with extensive statistical analysis capabilities built in.  The most recent edition of LogletLab 4.1 offer users numerous new features including an extended selection of fitting functions and advanced statistical analysis.

All versions of LogletLab are available free of charge.

Maglevs in the NY Times

An article about the Hyperloop magnetically levitated train in the 10 August 2017 New York Times quotes Jesse Ausubel:

Why Even the Hyperloop Probably Wouldn’t Change Your Commute Time  

Humans have historically tended to travel about half an hour to work, regardless of how fast the mode of transportation.

We first studied maglevs during the 1980s as part of a National Academy of Engineering project on cities and infratructures.  Not enough has changed.

Concrete Life Cycle Assessment

PHE researcher Iddo Wernick co-authored a recent article, Comparative LCA of concrete with natural and recycled coarse aggregate in the New York City area, published in The International Journal of Life Cycle Assessment. Congratulations to the main co-authors, professors Ardavan Yazdanbakhsh and Larry Bank and student Thomas Baez, in the Department of Civil Engineering at City College of New York.
