Permittivity
Wednesday, March 29th, 2017
12:00 – 1:00 PM, SH 308
Join SIAM in hosting Joseph Gaone for a talk revolving around Permittivity
Abstract: In microwave heating the complex permittivity determines how the energy propagates and is absorbed by materials. It is necessary to have an accurate way to experimentally determine this parameter from materials for use in modeling and engineering microwave applications. I will discuss this work of meauring permittivity from a summer internship for the Air Force Research Laboratory at Kirtland Air Force Base. The second half of the talk will discuss how permittivity can be used to control the uncontrollable microwave heating event known as thermal runaway. This unfavorable effect can lead to catastrophic failures of materials. This new proposed method of control may lead to better efficiency in microwave devices.
Control Theory: A Brief Introduction
Wednesday, February 1, 2017
4:00 – 5:00 PM, SH203
Join SIAM in hosting Haocheng Li for a talk on the basics of Control Theory.
Abstract: Control system technology is a ubiquitous technology that shapes the modern world. From the cell phones to automobiles, legged robot to manufacturing plant, the technology gives us the ability to influence physical systems and perform the desired task. I will give a brief overview of the control science which is in almost every engineering systems. Three major techniques, the frequency domain analysis, Lyapunov method and optimal control, will be discussed. To gain the key insights of control science, the intuition and perspective of each control techniques are shown. The fundamental concepts such as the output, actuation and stability will be covered through concrete example.
Student Speaker: Data Streams and Adaptive Estimation
Tuesday, December 13, 2016
4:00 – 5:00 PM, SH106
Join SIAM in hosting Josh Plasse from the Imperial College of London for a discussion of Data Streams and Adaptive Estimation.
Abstract: Data streams are potentially unending sequences of ordered observations that are subject to unknown temporal variation. The mining of these streams pose several challenging problems to the statistics and machine learning communities. This talk will introduce data streams and discuss why performing inference on them is a non-trivial task. We then discuss a framework which allows for temporally adaptive parameter estimation for well known distributions.
LaTeX Workshop – Crash Course
Thursday, November 3, 2016
4:00 – 5:00 PM, SH003
We are excited to host a graduate and undergraduate-led crash course on using LaTeX, a documentation preparation system that is popular in the publication of scientific papers. Those who attend can expect to learn about installation/setup, math environments, report formatting, Beamer (slides), and inserting graphics. This will be a great opportunity for those looking to add professionalism to their scientific papers or just looking for a new skill. Feel free to bring your own laptop!

Student Talk from Brown University – Modeling Transport of RNA Molecules in Frog Egg Cells
Thursday, September 22, 2016
3pm – 4pm, SH304
We are excited to host our speaker Veronica Ciocanel, PhD student from Brown University Applied Mathematics Department, to present a student talk about her research area, Modeling Transport of RNA Molecules in Frog Egg Cells.
Abstract: Messenger RNA transport to certain cell locations is essential for the development of the egg cell and embryo in the frog Xenopus laevis. This accumulation of RNA at the cell edge is not well understood, but is thought to depend on diffusion, bidirectional movement and anchoring mechanisms. We test these proposed mechanisms using differential equations models and analysis, informed by parameter estimation. Our results for effective diffusion coefficients and velocities of RNA suggest different dynamics in various regions of the healthy and mutant cell cytoplasm, and can propose directions for new experiments.
MATLAB Workshop – Fractals in Video
Friday, September 2, 2016
3pm – 5pm, SH003
We are excited to announce the first workshop of this academic year, Fractals in Video! We will start with a brief introduction to mathematical concepts behind fractals and then straight to MATLAB code. No experience needed! We will teach you everything you need to make a cool video that shows the evolution of Mandelbrot set as the resolution increases. Please come and join us!
FAQ: Is there free pizza and soda?
Sorry, the workshop is in a computer lab. But, we do have Sniker bars available at the end of the workshop!
