Predict the Future … With Math!

art2_150x197As Math Awareness Month (MAM) winds down, we wanted to leave you with another post! The goal of MAM is to increase public understanding and appreciation for mathematics. This year’s theme is “The Future of Prediction”. Many may not realize that mathematics and statistics are widely used to predict a number of things, such as, the outcome of a ball game, the results of elections, U.S industrial production of oil and natural gas prices, and even your health. Joe Kincaid, Senior Business Process Engineer of Blue Cross and Blue Shield, determined that the healthcare industry could forecast the likelihood of coronary heart disease through the use of mathematics, statistics, and technology advancements, which he discusses in his essay “To your Health”.

Update: SIAM Committee on Science Policy

SIAM’s Committee on Science Policy (CSP) held its regular Spring meeting on March 28 and 29 to meet with key decision-makers at federal agencies and in Congress to better understand the environment for research and to influence congressional legislation and federal programs related to applied mathematics and computational science.  The committee met with representatives from various units within the National Science Foundation (NSF), the Department of Energy (DOE), the Department of Defense (DOD), and the National Institute of Standards and Technology (NIST) to learn more about the fiscal year (FY) 2017 budget request, discuss new research initiatives, and provide input on issues of concern to the SIAM community.   Read the rest of this entry »

Modeling robust use of pesticides

Adaptive control techniques can help manage pests more effectively

nugget_iconAs population growth, greater food consumption, competition for land use, and climate change pose challenges to world food production, managing loss of crop due to pests and weeds becomes increasingly important. While chemical pesticides offer effective means for control, potential loss of crop yield  is still significant, as is cost. Global potential loss from pests has been estimated to be between 50% and 80% of yield based on crop type.

In a paper published last week in the SIAM Journal on Applied Mathematics, authors Chris Guiver et al propose adaptive control techniques to model pest dynamics and management as a control system. Read the rest of this entry »

SIAM News: January/February Issue Now Available

The latest issue of SIAM News is now available online! Mathematics not only enhances scientific progress, but also hides within simple gestures we instinctively repeat every day. Such is the case when we turn on the lights. What does it take to ensure that every time we enter a dark room and flip the light switch, electricity is available and waiting for us to use? Read more about optimization and how one can generate electricity in a manner that is both satisfactory for consumers and efficient from the network point of view in the most recent issue of SIAM News.

Merck Researcher Jeff Sachs on mathematical models for drug discovery

Jeff Sachs of Merck Research Laboratories explains how mathematical models can make seemingly insurmountable amounts of data in medicine and biotechnology more manageable and informative. How can models be designed to uncover information we need from medical data in order to determine actions to be taken and decisions to be made in drug discovery and development?

Machine Learning for various applications

The extraordinary success of search engines, recommendation systems, and speech and image recognition software suggests that future advances in these technologies could have a major impact in our lives. In this talk, we discuss modern intelligent-algorithmic systems based on sophisticated statistical learning models and powerful optimization techniques. One can envision new algorithms that operate in the stochastic or batch settings, and that take full advantage of parallelism. We review our remarkable understanding of classical stochastic approximation techniques, and pose some open questions. The lecture concludes with a discussion of modern neural nets and the demands they impose on optimization methods.At the 2014 SIAM Annual Meeting Jorge Nocedal talked about all this and more.

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.

Mathematicians tackle global issues

 Philadelphia, PA– More than 100 academic institutions and scholarly societies have joined in a major world-wide initiative: Mathematics of Planet Earth (MPE) 2013. This year-long effort will highlight the contributions made by mathematics in tackling global problems, including natural disasters such as hurricanes, earthquakes, and tsunamis; climate change; sustainability; and pandemics. MPE2013 partners will sponsor workshops, research conferences, public lectures, outreach events, and educational opportunities for all ages.  Each country from a partner institution will host a special launch to the year.

MPE2013 enjoys the patronage of UNESCO, the United Nations Educational, Scientific, and Cultural Organization.  The Director-General of UNESCO, Irena Bokova, said, “UNESCO strongly supports this extraordinary collaboration of mathematicians around the world to advance research on fundamental questions about planet Earth, to nurture a better understanding of global issues, to help inform the public, and to enrich the school curriculum about the essential role of mathematics in the challenges facing our planet.” Read the rest of this entry »
