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.

#### 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. ...

#### Math models analyze long-term criminal activity patterns in a population

In a paper published last November in Multiscale Modeling and Simulation: A SIAM Interdisciplinary Journal, authors Henri Berestycki, Nancy Rodríguez, and Lenya Ryzhik show that the assumption of a population's natural tenden ...

#### Mathematically correcting over- and underexposure in photographs

Almost anyone with a camera or smartphone is sure to have noticed that taking pictures in bright conditions, such as a sunny day, can cause a loss of highlight details (or overexposure) in bright regions and a loss of shadow ...

#### Improving radiation therapies for cancer mathematically

In a paper published in December in the SIAM Journal on Scientific Computing, authors Li-Tien Cheng, Bin Dong, Chunhua Men, Xun Jia, and Steve Jiang propose a method to optimize radiation therapy treatments in cancer patien ...

#### Statistics research could build consensus around climate predictions

Vast amounts of data related to climate change are being compiled by research groups all over the world. Data from these many and various sources results in diﬀerent climate projections; hence, the need ...

#### A mathematical perspective of seasonal variations in Lyme disease transmission

Lyme disease is a common tick-borne illness caused by a bacterium, which is transmitted to humans through the bite of infected ticks. The transmission dynamics of Lyme disease is dependent on a variety of ...

#### 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 ...

#### An intersection of math and biology: Clams and snails inspire robotic diggers and crawlers (w/ Video)

Engineering has always taken cues from biology. Natural organisms and systems have done well at evolving to perform tasks and achieve objectives within the limits set by nature and physics.

#### Are you ready to retire? Mathematical models estimate the value of pension plans

There comes a time in each of our lives when we consider starting a pension plan –either on the advice of a friend, a relative, or of our own volition. The plan of choice may depend on various factors, ...

#### Seamless photography: Using mathematical models for image stitching

A photo captures only as much as the camera in use will allow, and is therefore limited by the field of view of the camera's lens. In the case of smartphones and many advanced cameras, the view from the lens ...

#### Tracking criminal movement using math: Will the next strike be near or far away?

One way to study criminal behavior and predict a criminal's next move is by analyzing his or her movement. Several mathematical models have addressed this in detail, in particular, the UCLA "burglary hotspot" ...

#### Using math models to make predictions: How vegetation competes for rainfall in dry regions

The greater the plant density in a given area, the greater the amount of rainwater that seeps into the ground. This is due to a higher presence of dense roots and organic matter in the soil. Since water is ...

#### Stabilizing aircraft during takeoff and landing using math

One of the lesser known concerns about commercial aircraft is their stability on the ground during taxiing, takeoff, and landing. During these processes, planes must maintain stability under various operating ...

#### Surges in latent infections: Mathematical analysis of viral blips

Recurrent infection is a common feature of persistent viral diseases. It includes episodes of high viral production interspersed by periods of relative quiescence. These quiescent or silent stages are hard ...

#### Mathematical models to better combat HIV

The first few hours to days following exposure to human immunodeficiency virus (HIV) can be of critical importance in determining if infection occurs in a patient. But the low numbers of viruses and infected cells at this ...
