For thin liquid film coating viscous flows on different shapes of rotating substrates (spherical, cylindrical), taking into account surface tension and gravity, we show how stability of stationary solutions depends on values of the contact angles. We also show that for a certain range of contact angles in a partial wetting regimes lubrication ap...

In this talk we will describe methodologies to localize both a single and a team of vehicles navigating in a complex environment without GPS. During the first part of the talk, we will consider the situation when vehicles (or a single vehicle navigating in an environment with multiple beacons) can measure their relative (inter-vehicle) distances...

The "Un sac de Billes" Lithographs are based on French Holocaust survivor, Joseph Joffo's (1931-) memoir "Un sac de Billes" (A Bag of Marbles) published in 1973. The book is based on Joffo and his brother's experience during World War II, after their father gives them 5000 francs and instructions to flee Nazi-occupied Paris and, somehow, get to ...

Within the context of satellite remote sensing, a common processing problem is the interpolation of irregularly sampled sensor data onto a regularly spaced grid as required for use in downstream scientific data products. Motivated by the need to solve this problem in the context of CubeSat radiometer platforms under development at MIT Lincoln La...

Determining trend and implementing detrending operations are important steps in data analysis. Traditionally, various extrinsic methods have been used to determine the trend, and to facilitate a detrending operation. In this talk, a simple and logical definition of trend is given for any nonlinear and non-stationary time series as an intrinsical...

Let A be a finite set of integers. The sum set, A+A, is the setof pairwise sums from A and the product set, AA, is the set of pairwiseproducts. Erdos and Szemeredi conjectured that either the sum set or theproduct set should be large, A+A+AA is (almost) quadratic in A forany subset of integers. This problem (and some of its variants) became oneo...

Two approaches to characterizing reflected diffusions include the submartingale problem formulation or a formulation in terms of the Skorokhod problem and stochastic differential equations. We introduce these formulations for a large class of piecewise smooth domains and, under suitable assumptions, we show that well-posedness of the submartinga...

We will present some convergence results for the stochastic 2D Navier Stokes equations. The talk will focus on the strong speed of convergence of a splitting method; this is a joint work with H. Bessaih and Z. Brzezniak.

The use of integrodifference equations in the study of the roleof dispersal on populations with discrete generations hasgenerated interesting mathematical problems and expanded ourunderstanding of their spatio-temporal dynamics. Here, we usediscrete-time epidemic models that can be reduced to a singlemap for the infectious class, It+1 =g(It), wh...

This is one of a series of six digital illustrations by the artist Moira Villiard. This sixth illustration, titled “On The Side…,” shows a takeout box containing fried rice and a spoon next to a baggie with blue hand-sewn face masks inside, all on top of a bright red background. On one flap of the takeout box are the words, “On the side…” The fo...
