Submission Deadlines for ICIAM 2015 Announced

The International Congress on Industrial and Applied Mathematics (ICIAM 2015) will be held in Beijing, China on August 10-14, 2015. Following recent traditions, SIAM will not hold its Annual Meeting in 2015 in order to support the ICIAM Congress. SIAM encourages those who wish to participate to submit minisymposium proposals or contributed talks directly to the Congress organizers. For those planning to participate, some key deadline information is now available.

The organizers of ICIAM 2015 have recently posted the submission dates on the conference web site here.  Note, for example, that minisymposium proposals may be submitted starting March 31, 2014, with a final deadline of September 30, 2014.

SIAM has applied to the National Science Foundation for funding for a limited number of people from U.S. institutions to travel to the Congress. Application details will be posted in the near future. Priority will be given to students and early career researchers.

Scientific Computation In Next Generation Innovation – An Aerospace Perspective [Video]

For technologically mature industries or those with high barriers to change, innovation is a challenge. One low risk, low cost innovation path is to radically improve performance while minimizing change to existing infrastructure. In his presentation at the 2013 SIAM Annual Meeting and Conference on Control and Its Applications, Nazareth Bedrossian of Halliburton used a historical perspective on spacecraft optimal control to show how scientific computation can act as the enabler for next generation innovation. Real world examples were presented where radical leaps in performance without altering spacecraft hardware or software has been achieved.

The mathematics of electricity costs [Video]

In this video from the 2013 SIAM Annual Meeting, Alejandro Jofré of Universidad de Chile considers a wholesale electricity market model with generators interacting strategically and general networks including externalities such as transmission losses. Previous work shows how mechanisms such as the case when prices correspond to the Lagrange multipliers of a centralized cost minimization program allow the producers to charge significantly more than marginal price. This situation originates an important regulatory problem. In this presentation we consider an incomplete information setting where the cost structure of a producer is unknown to both its competitor and the regulator. We derive an optimal regulation mechanism and compare its performance to the “price equal to Lagrange multiplier”. Watch the video:

Jamology – the mathematics of traffic jams [Video]

Jamming phenomena are seen in various transportation system including cars, buses, pedestrians, ants and molecular motors, which are considered as “self-driven particles”. This interdisciplinary research on jamming of self-driven particles has been recently termed “jamology”. This is based on mathematical physics and includes engineering applications as well. In his talk at the 2013 SIAM Annual Meeting, Katsuhiro Nishinari of the University of Tokyo traced the background of this research: simple mathematical models, such as the asymmetric simple exclusion process and the Burgers equation, were introduced as the basis of all kinds of traffic flow. This was then extended in order to account for various traffic phenomena, and the comparison between theory and experiment was given to show that the models are able to capture fundamental features of observations.

The mathematics of conservation decision making [Video]

Species are currently becoming extinct at least 100 times the background rate. The resources available to save biodiversity are inadequate. Consequently we need to optimise the return on investment from conservation decisions. In this talk at the 2013 SIAM Annual Meeting, Hugh Possingham of the University of Queensland showed how optimization tools are being used to solve conservation problems such as reserve system design, and allocating funds to threatened species management.

Social Networks as Information Filters [Video]

Social networks, especially online social networks, are driven by information sharing. But just how much information sharing is influenced by social networks? A large-scale experiment measured the effect of the social network on the quantity and diversity of information being shared within Facebook. While strong ties were found to be individually more influential, collectively it is the weak ties that wield more influence and provide more diverse information exposure. This sharing behavior not only generates large cascades, but can also cause information to evolve. Lada Adamic of the University of Michigan spoke about all this and more with engaging examples at the 2013 SIAM Annual Meeting. Watch the video!

Travel Grants for ICM 2014

The American Mathematical Society has applied to the National Science Foundation (NSF) for funds to permit partial travel support for U.S. mathematicians attending the 2014 International Congress of Mathematicians (ICM 2014) August 13 – 21, 2014, in Seoul, Korea.  Subject to the award decision by the NSF, the Society is preparing to administer the selection process, which would be similar to previous programs funded in 1990, 1994, 1998, 2002, 2006 and 2010.

Instructions on how to apply for support are available on the AMS website.  The application period is September 1 – November 15, 2013.  Read the rest of this entry »

Biology and robotics work hand in hand, and claw to claw

Discover the math behind biologically-inspired robots at a free public event, on Wednesday, July 10, at 6:15 p.m. at the Town and Country Resort & Convention Center in San Diego.

San Diego, CA—Snails can move upside down, sideways, and backwards on almost any surface. Razor clams can dig and bury themselves in the sand with remarkable speed and agility. Swimming microorganisms are highly efficient molecular machines that rapidly propel themselves through dense fluids.

Nature might be the most innovative designer and engineer, with the world as a laboratory at its disposal. The amazing proficiency displayed by animals in crawling, swimming, flying, walking, and running—movements performed perfectly within the limits of the laws of physics—presents a natural observation ground for robotics and automation.

During a free public lecture at the Annual Meeting of the Society for Industrial and Applied Mathematics (SIAM) on July 10 in San Diego, Professor Anette Hosoi of the Massachusetts Institute of Technology will discuss how these natural mechanisms can be used to guide engineering design and develop state-of-the-art robots.

Lexing Ying to receive James H. Wilkinson Prize

San Diego, CA–Stanford University’s Lexing Ying will receive the 2013 James H. Wilkinson Prize in Numerical Analysis and Scientific Computing.

Dr. Ying’s research, concerned with the design of fast and accurate numerical algorithms for fundamental problems in scientific computing, displays his exceptional skills as both mathematical analyst and computational scientist, combining ideas from approximation theory, probability, special functions theory, multiscale analysis and parallel computing. Dr. Ying has made outstanding contributions in many areas, including the rapid evaluation of oscillatory integral transforms, high frequency wave propagation and the computation of electron structure in metallic systems.

Margaret Cheney to deliver the AWM-SIAM Sonia Kovalevsky Lecture

San Diego, CA—The Association for Women in Mathematics (AWM) and the Society for Industrial and Applied Mathematics (SIAM) are pleased to announce Margaret Cheney of Colorado State University and Naval Postgraduate School as the 2013 AWM-SIAM Sonia Kovalevsky Lecturer.

Dr. Cheney is being bestowed this honor in recognition of her broad line of research that is coupling disparate radar solutions in ways previously unrecognized. Her application of Microlocal Analysis to high-frequency radar scattering, a method largely unknown to the radar community, has proven to be especially relevant to the problems of radar target detection, tracking and imaging.
