Van der Waals Force Re-measured, may Help Improve Fundamental Simulation Methods

November 26, 2014 10:16 am | by Forschungszentrum Jülich | News | Comments

Van der Waals forces act like a sort of quantum glue on all types of matter. Using a new measuring technique, scientists from Forschungszentrum Jülich experimentally determined for the first time all of the key details of how strongly the single molecules bind to a surface. With an atomic force microscope, they demonstrated that the forces do not just increase with molecular size, but that they even grow disproportionately fast.

Applications for Randomness

November 17, 2014 8:49 am | by Mark Anawis | Blogs | Comments

The mathematician, Robert R. Coveyou, said: “The generation of random numbers is too important to be left to chance.” Random numbers are used in sampling, simulations, modeling, data encryption, gambling and even musical composition. A random number is one selected from a set of equally possible values. Any sequence of random numbers must be statistically independent of the others.

The World of Supercomputing Must Become Data Centric

November 17, 2014 8:37 am | by David Turek, IBM | Blogs | Comments

It has been a commonly held belief that supercomputing capability is a predictable phenomenon with the "fastest" system in the world increasing in power by three orders of magnitude about every 11 years. I put the term "fastest" in quotes, because very few ask the question: Fastest in what way? It turns out that this notion of "fastest" is limited to a narrow consideration of system performance that focuses on floating point capability.

Small and Medium Enterprises Enter the Limelight

A decade of close scrutiny has shed much more light on the technical computing needs of small and medium enterprises (SMEs), but they are still shrouded in partial darkness. That’s hardly surprising for a diverse global group with millions of members ranging from automotive suppliers and shotgun genomics labs to corner newsstands and strip mall nail salons.

Folk wisdom can sometimes be right on target. For example, there’s that old bromide about leading a horse to water. In this case, the water is high performance computing, and the reluctant equine is the huge base of small- to medium-sized manufacturers in the U.S. According to the National Center for Manufacturing Sciences, there are approximately 300,000 manufacturers in the U.S. Over 95 percent of them can be characterized as SMMs.

New Model Provides Accurate Traffic Flow Predictions

November 7, 2014 2:46 pm | by David L. Chandler, MIT | News | Comments

A reliable way of predicting the flow of traffic could be a great convenience for commuters, as well as a significant energy-saver. During an emergency evacuation following a natural disaster, reliable predictions of the best routes could even be a lifesaver. Now a team of researchers from MIT, the University of Notre Dame, and elsewhere has devised what they say is an effective and relatively simple formula for making such predictions.

JMP 11: Remarkable Statistics, Graphics and Integration

November 7, 2014 10:30 am | by John A. Wass, Ph.D. | Articles | Comments

It should come as no surprise to readers of this column that JMP is a personal favorite and, along with SAS, one of my most-used programs. There are a number of reasons for this. Of the many advantages that most packages can offer, breadth and depth of the statistics offered, quality of the diagnostics, interconnectivity of graphics with both data and analyses, and ease-of-use issues are uppermost in my mind as most desirable.
