Reliable power system operation requires the continuous balance of supply and demand at every moment in time. However, large-scale integration of variable generations such as solar and wind can significantly alter the dynamics in a grid because wind and solar resources are intermittent. Continue reading

From October 9 – 13. 2013 many of the AIM staff were volunteering at a golf tournament, the Frys.com open. This is a PGA tour event and is a benefit to many charities including AIM. One of the days was designated AIM day to highlight the activities at AIM and one of the things the tournament directors asked us to do was make up a math+golf related quiz. Continue reading

It is October. Very soon the inspiring canvas of the Fall foliage will be gone and we will raise our eyes once in a while to enjoy an unexplained beauty of the branched architecture of the naked trees. Yet, there might be more than a shear aesthetic pleasure in those views and this is what today’s blog is about. Continue reading

Modern society is increasingly dependent on imaging technology. Medical imaging has become a vital part of healthcare, with X-ray tomography, MRI, and ultrasound being used daily for diagnostics and treatment monitoring of various diseases; meteorological radar predicts weather, sonar scanners produce sea-floor maps, and seismometers aid in geophysical exploration. Continue reading

There are two standard ways to restrict harvesting of fish in order to maintain or improve the population. One way is to establish marine protected areas where fishing is prohibited and the other is to allow fishing everywhere but at something less than maximal capacity. Just a few days ago I noticed an interesting preprint in ArXiV that sets up a mathematical framework for deciding whether protected areas should be used and, if so, where they should be established.
