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.

What You Missed: Women in Data Science Conference

By: Margot Gerritsen

Data Science is one ofthe hottest fields in industry, government, and academia. The demand for data scientists far exceeds the supply of qualified candidates. Good data science requires an interdisciplinary and inclusive approach: team work is common, and diversity is highly desirable. Yet, women (and URM, or under-represented minority) continue to be significantly underrepresented and under supported. Read the rest of this entry »

Nugget: New SIR-Network Model Helps Predict Dengue Fever Epidemic in Urban Areas

Mathematics is often implemented in healthcare and medical research. From health management to the bio-pharmaceutical fields, math modeling can be used to predict the spread of diseases, how to prevent epidemics and so much more. An article “SIR-Network Model And its Application to Dengue Fever,” authored by Lucas M. Stolerman, Daniel Coombs and Stefanella Boatto, published recently in the SIAM Journal on Applied Mathematics introduces a new mathematical model which offers a simplified approach to studying the spread of the infectious virus, Dengue fever, in urban areas, specifically breaking down the epidemic dynamics across a city and its varying neighborhoods and populations.

Nugget: Improving Electric Motor Efficiency Via Shape Optimization

Philadelphia, PA – In our competitive global society, successful and economical design of automotive and industrial structures is crucial. Optimizing the geometry of individual pieces of complex machines improves performance and efficiency of the entire device.

To achieve this, the automotive and aeronautic industries often rely on shape optimization, an approach that uses modeling to create a framework for making devices as smooth and efficient as possible. “A smoother rotation of the rotor can increase the energy efficiency of the motor, and at the same time reduce unwanted side effects like noise and vibrations,” says mathematician Ulrich Langer.
