We study the design of reliably connected networks. Given a graph with arcs that may fail at random, the goal is to select a minimum cost set of arcs such that a connectivity requirement is met with high probability. We first compare this model with a well-known deterministic model of reliable network design: survivable network design. We demonstrate that, if... Read More
Set functions, i.e., real mappings form the family of subsets of a nite set to the reals are known and widely used in discrete mathematics for almost a century, and in particular in the last 50 years. If we replace a finite set with its characteristic vector, then the same set function can be interpreted as a mapping from the set of binary vectors to the reals. Such... Read More
The software systems commonly used to solve linear and integer programming problems today make use of oating-point computation and the inexactness of these computations can lead to errors in the returned results. Although such numerical errors are sometimes tolerable, there are situations when exact results are necessary. This talk will describe a variety of methods... Read More
How should the Centers for Disease Control and Prevention revise national immunization recommendations so that gaps in vaccination coverage will be filled in a cost-effective manner? What is the most cost-effective way to use limited HIV prevention and treatment resources? To what extent should local communities stockpile antibiotics for response to a potential... Read More
One of the core technologies for obtaining protein mixtures is provided by the two dimensional polyacrylamide gel electrophoresis (2D-gel). In order to analyze variations in the protein gels obtained from different groups that account for biological variations we must first eliminate distortions to properly align images. The image alignment is recognized as a major... Read More
Public Lecture - "Industrial Engineering - Quo Vadis? One Man’s Idiosyncratic View of His Profession"
Industrial engineering was born in the work of F. W. Taylor at the Midvale Steel Company, and grew under the moniker of “scientific management.” Peter Drucker famously ascribed much of modern economic prosperity to the success of Taylor and those who followed.... Read More
Public Lecture - "How an Engineering Education affected my career"
Mr. Young will discuss how his Industrial Engineering education helped him function in the motion picture film and entertainment industry by successfully merging technology and art.
Public Lecture - "The Role of Embedded Optimization in Smart Systems and Products"
Many current products and systems employ sophisticated mathematical algorithms to automatically make complex decisions, or take action, in real time. Examples include recommendation engines, search engines, spam filters, on-line advertising systems, fraud... Read More
Public Lecture - "What Does a Rocket Scientist Really Do?"
When describing something dreadfully simple or blatantly obvious we often proclaim "It is Not Rocket Science." Yet while we may readily agree that "rocket science" is not a synonym for "simple", it sheds no light on what a rocket scientist really does. In this talk I will reflect on... Read More
