On Modeling, Simulating and Verifying a Decentralized Mission Control Algorithm for a Fleet of Collaborative UAVs (COLLOQUIUM - March 20, 2013)

Who: Dr. Hong Liu
Location: 205 Eliz @ 3:00
It can be relatively easy to correctly design a centralized mission control algorithm for a fleet of unmanned aerial vehicles (UAV) to achieve optimal mission efficiency. However, the fault intolerance of the algorithm makes the fleet risky for the missions in noisy communications environment. This talk presents a Decentralized Mission Control (DMC) algorithm for coordinating a fleet of UAVs to accomplish a specific mission. The symbolic model of the UAV fleet configuration and the software processes are imitated to the Berkley UAV systems, which facilitate the peer-to-peer communication and the environment awareness. The design goal of the DMC algorithm is that the UAVs work either cooperatively to achieve the highest efficiency under normal communication modes or adaptively to guarantee the safety of UAVs under various fault modes. The communication protocol of DMC algorithm mostly depends on message broadcasting in order to minimize the dependency on ground station. The task assignment schema of DCM algorithm depends on the modes of the environment variables. It is derived from the Hungary Algorithm, which attains the optimal assignment for equal numbers of tasks and agents. Formal method is used to verify the safety and progress properties such as tolerance to faults and free of deadlocks. The real-time interactions of the system are modeled as a nexus of UPPAAL automata and verified against the expected properties specified as a list of temporal CTL queries. A C# program is used to simulate and measure the mission efficiency.

Bistable Waves in Discrete Inhomogeneous Media (COLLOQUIUM - November 13, 2012)

Who: Dr. Brian Moore
Location: EH 205
Bistable differential-difference equations are crude models for conduction of electrical impulses in the nervous system. Employing a piecewise linear approximation of the nonlinearity, one can derive exact solutions of this system such that a portion of the medium for conduction is deteriorated, characteristic of diseases that affect the nervous system. Using Jacobi operator theory and transform techniques, wave-like solutions are constructed for problems with essentially arbitrary inhomogeneous discrete diffusion, and these solutions directly correspond to monotone traveling wave solutions in the case of homogeneous diffusion. A thorough study of the steady state solutions provides necessary and sufficient conditions for traveling waves to fail to propagate due to inhomogeneities in the medium. Solutions with nonzero wave speed are also derived, and we learn how the wave speed and wave form are affected by the inhomogeneities. Brian Moore, Assistant Professor, Department of Mathematics, University of Central Florida will give this talk at 2:30PM

A Ranking of State Climate Policies (COLLOQUIUM - October 21, 2011)

Who: Dr. J. Anthony Abbott
Location: EH 205 - 3:30
Individual states and academic institutions have taken leadership on climate change policy in the United States. Without unified national policy, a patchwork of state policies fosters geographic variation among climate action plans (CAPs) for American College and Universities Presidents%u2019 Climate Commitment signatories. Correlation among indexes rating state climate policy and signatory CAPs and spatial analysis indicate that states with aggressive climate policy foster aggressive policy within their academies. Reflection on the national scale suggests that although state policies help combat climate change, they could be more significant if articulated within a more comprehensive national policy. Refreshments will be served

Software Engineer Ranked Best Job for 2011 (NEWS - April 20, 2011)

TMC Net, April 28 The new Jobs Rated report from job site CareerCast indicates that Software Engineer is the top ranked job for 2011. Identifying a software engineer as someone who can design and create software for everything from operating systems to cell phone apps to interactive games, the site suggested that the push toward Web applications and cloud computing is opening up the market for software engineers. More companies are designing apps for smartphones and tablets, while cloud computing is creating a need for software that can be hosted online. In addition to its increased diversity of job responsibilities, software engineering scored high marks for growth potential and competitiveness. Those good grades mean that software engineers are less bound to employers or vulnerable to outsourcing, according to CareerCast. And as a result, the overall stress ranking for the job has also improved this year. Overall, CareerCast sees software engineering as offering a comfortable work environment, few physical demands, better than average income, relatively low stress levels, and strong hiring. The site estimated the annual salary at $87,140.

This talk will address the history of cryptography beginning with the Enigma used by the Germans in WWII and broken by world famous Mathematician/ Computer Scientist Alan Turing. It will continue down to todays advanced crypto systems such as RSA, PGP and Elliptic Curve cryptography. The lecture will point out the key role that cryptography plays in the future of e-commerce and the new products and ways of doing business that results when secure communications through cryptography is available. Light refreshments will be served in the Seminar Room at 2:40. Cultural Credit is available.

Calibration of Stable Distributions to Option Prices (COLLOQUIUM - March 28, 2011)

Who: Dr. Jeff Hamrick
Location: room 213 LBC 12:00-1:00PM
To anyone looking through a chain of call and put option prices at Yahoo! Finance, it is probably clear that these prices encode the market's opinion about the future random return on the underlying stock. In a remarkable paper from earlier this decade, Jackwerth and Rubinstein use a nonparametric technique to obtain an estimate of this probability distribution. Unfortunately, their technique generates return distributions that are bounded from above and below. This feature would most likely be considered unrealistic by anyone whose retirement portfolio has tanked over the past few years. In contrast, we adopt the perspective that stock returns are independent and identically-distributed stable random variables -- generalizations of the familiar bell-shaped curve that readily admit fatter tails and sharp skewness. After deriving the associated probability distribution required to price call and put options in an arbitrage-free fashion, we develop a program of optimization for obtaining best-fitting parameters that govern the (assumed) stable distribution of returns. Lunch will be served.

Expert Engines and Drools (COLLOQUIUM - March 24, 2010)

Who: Sam Romano, Lock heed Martin
Location: EH 205
The Drools Library (officially known now as JBoss Rules) is a forward-chaining inference based rules engine (also known as an Expert System or Knowledge Engine). It is the first widely supported open source rule engine with an implementation based on the Rete Network Algorithm by Charles Forgy, with additions made for the java object orientated paradigm. Drools is currently in version 5.0, and has expanded its feature set to not only be an expert engine, but also handle other services required in enterprise systems/business policies such as a Complex Event Processor/Event Stream Processor (Drools Fusion), work flow engine (Drools Flow), and even a generic plan solver (Drools Solver) for handling problems related to Operations Research. While many businesses employ Drools in enterprise-type situations such as Insurance companies for application handling, or security systems for authentication, it also has found many uses in Logistics (FedEx, Lockheed Martin) and the health industry with medical services and diagnosis systems. We will cover some of the internals of Drools, with examples that exemplify Drools features, and how its internal implementation based on ideas developed 30 years ago allows users in our modern day to apply and build abstract, extensible systems.

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.

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.
