Credit Contagion or Credit Confusion? Evidence from Fixed Income Markets (COLLOQUIUM - November 6, 2008)
Who:
Jeff Hamrick
Location:
EH 205, 4pm
Are different slices of fixed income markets more dependent during times of crisis than during normal times? We call this increase in dependence during times of crisis credit contagion, and define this concept through a local correlation function very similar to the usual correlation coefficient. Surprisingly, an analysis of bond yield spreads, bond indices, credit default swap indices, and credit default swaps suggests that fixed income markets have not experienced credit contagion during crises like the 2007-2008 subprime mortgage credit crisis. Instead, these measures have tended to become less correlated or even conditionally uncorrelated---a concept we call credit confusion.
Refreshments will be served @ 3:30 in room 214 Eliz. |

AI and Robotics: Theory, Practice, Applications, and Interesting Projects (COLLOQUIUM - April 9, 2008)
Who:
Dr. Claude Fennema
Location:
EH 205 - 3:30PM
 Artificial Intelligence (AI) is a research field full of interesting questions for philosophers, psychologists, cognitive scientists, linguists, and computer scientists. It has been a research enterprise filled with lively debate, controversy, and interesting spinoffs. In this talk, I will present my view of the AI enterprise, of which robotics is a very important part. I will talk about theoretical issues, work that has been done, applications, interesting work that my students have completed, and we can discuss ideas for future projects. Albert, my mobile robot, will be present and I will show a short movie of "him" in action. |

Chain codes and Iterated 3-D Transformations (COLLOQUIUM - April 3, 2008)
Who:
Dr. Carl Weiman
Location:
EH210
Dr Weiman says: I have always had a deep emotional and intellectual affinity
for cellular automata, chaos, and fractals. I have stumbled into two
systems which involve interesting new aspects of all three areas, and
am eager to share-dissemminate to interested people capable of taking
the math and programming far beyond my abilities.
One of these is a chain code devised by a quantum physicist (Jerry
Rothstein) from the Manhattan Project to illustrate deterministic
chaos before a name for the subject had materialized. It was the
topic of my dissertation.
The second is the system of iterated 3-D transformations which
exhibits very interesting structures related to differential geometry,
topology, group theory, in math. In biology it applies to alpha and
beta structures in polymers such as protein, with explicit controls
for coiling and wave-like motions of structures such as cilia and
flagellae. In physics it perhaps relates to superstring
configurations in Calabi-Yau topologies. The java project I have
developed gives turnkey controls to non-programmers in all these
fields. I would like to demo it and the Rothstein Code java software
and give users access via jar or source code. |

Solitons and the KdV Equation (COLLOQUIUM - April 3, 2008)
Who:
Dr. Tom Vogel
Location:
EH 205
Solitons are mathematical solutions to certain types of nonlinear partial differential equations. The first (recorded) observation of a naturally occurring soliton was in 1834 by John Scott Russell. It wasn%u2019t until 1895 that the mathematics of such solutions was understood. This talk will discuss solitons in both a historical and technical context. The first mathematical derivation of a soliton solution was in an equation governing waves on a shallow water surface. Today, this equation is known as the Kortweg-de Vries (KdV) equation. This talk will include derivation(s) of solitons of the KdV equation from both a conventional approach, as well as a more non-conventional variational approach. Systems including those which admit atmospheric, optical, and other physical solitons will also be discussed. |

To Idle or Not to Idle: That is the Question (COLLOQUIUM - December 5, 2007)
Who:
Charles Reilly
Location:
EH 205
A mathematical model is suggested for finding the optimal block size under block queuing for a single-channel queue at a drive-through service facility. With block queuing, a queue is partitioned into an active section and a passive section, where drivers are asked to turn off their engines until the active section clears. Our model prescribes a block size, that is, the maximum number of vehicles in the active queue, that minimizes the expected amount of fuel consumed by vehicles in the queue. The model can assess the effects of traffic intensity, the service-time variance, and the proportion of compliant drivers in the passive queue on the optimal block size and on fuel consumption in the queue. |

The Google File System (COLLOQUIUM - November 26, 2007)
Who:
Andrew Moedinger (Stetson Alum!), Software Engineer, Google
Location:
Rm 205 Elizabeth Hall
Ever wonder how Google stores petabytes of data and accesses it in real time? The answer is the Google File System: a scalable distributed file system that provides high performance and fault tolerance while running on inexpensive commodity hardware. This talk will discuss some of the technical details of the Google File System, as well as life at Google as a software engineer. Will begin at 2:30 pm |
