The Society for Industrial and Applied Mathematics, (SIAM) was formed in 1951 in Philadelphia, Pennsylvania. Since its inception, SIAM has grown to over 12,000 members with sections in the U.K., East Asia, Bulgaria, Ireland and Argentina. The primary purpose of SIAM is the industrial application of mathematics. The motto is “Science and Industry Advance with Mathematics.” Its membership comprises engineers, scientists, technicians, mathematics and multi-disciplinary professionals.

### Mathematical models with complicated dynamics for disease study

A paper to be published this week in the SIAM Journal on Applied Dynamical Systems presents a mathematical model to study the effects of individual movement on infectious disease spread.

### Should a political party form a coalition? Voters and math decide

Mathematical ideas and tools are often used to describe aspects of large macroscopic systems. Examples abound in areas as varied as finance to psychology. In a paper published last month in the SIAM Journal on Applied Mathematics, ...

### Modeling storm surge to better protect Texas

The recent floods in Texas have caused some of the worst flooding since Hurricane Ike in 2008, causing the rainiest month in the state's history.

### Decision cascades in social networks

How do people in a social network behave? How are opinions, decisions and behaviors of individuals influenced by their online networks? Can the application of math help answer these questions?

### When vaccines are imperfect: What math can tell us about their effects on disease propagation

The control of certain childhood diseases is difficult, despite high vaccination coverage in many countries. One of the possible reasons for this is "imperfect vaccines," that is, vaccines that fail either due to "leakiness," ...

### Insightful mathematics for an optimal run: Mathematical equations can help improve athletic performance

Sure, we can become better runners by hydrating well, eating right, cross training, and practice. But getting to an optimal running strategy with equations? That's exactly what a pair of mathematicians from France propose ...

### Where is that spacecraft? Statistically measuring uncertainty for space surveillance

Space surveillance is inherently challenging when compared to other tracking environments due to various reasons, not least of which is the long time gap between surveillance updates. "Unlike the air and missile defense environments ...

### Overcoming structural uncertainty in computer models

A computer model is a representation of the functional relationship between one set of parameters, which forms the model input, and a corresponding set of target parameters, which forms the model output. A true model for ...

### Math models enhance current therapies for coronary heart disease

Coronary heart disease accounts for 18% of deaths in the United States every year. The disease results from a blockage of one or more arteries that supply blood to the heart muscle. This occurs as a result of a complex inflammatory ...

### Putting a number on opinion dynamics in a population

Opinion formation in a large population is influenced by both endogenous factors, such as interaction with one's peers—in-person and via social media—as well as exogenous factors, such as the media, of which mainstream ...
