Projects in 2001–2002


Fair, Isaac, and Company, Inc.: Optimizing an Online Query System

Advisor
Lesley Ward

The Fair, Isaac clinic team's goal is to develop a method for constructing dynamic online surveys. We will construct an algorithm which will choose the next survey question based on previous responses, in order to maximize the amount of information about the respondent in the fewest number of questions. When predictions are made based on the respondent's information, the algorithm will adjust its parameters for both correct and incorrect predictions to be more accurate for future survey-takers.

Northrop Grumman: Noise Prediction for Onboard Infrared Detectors as a Function of Temperature

Advisor
Henry Krieger

Infrared detectors onboard geosynchronous satellites are used to detect targets of interest. The performance of detectors changes as temperatures change. As temperature increases, noise output increases. The goal of this project is to mathematically model the noise-temperature relationship, utilizing existing data from on-orbit systems. Time permitting, we will propose extrapolation methods that will predict the model's behavior at even higher temperatures. Deliverables will include a final report and documented software prototype that aids Northrop Grumman in extracting signals from the noisy sensor data.

Space Systems/Loral: Efficient Satellite Orbit-Raising in 3D Using Ion Propulsion

Advisor
Anette Hosoi

Space Systems/Loral 2001-2002 Clinic team will use nonlinear programming and direct collocation methods to find efficient low-thrust orbit transfers. We plan to use a realistic three-dimensional model of orbital dynamics including optimal thrust steering, possible perturbation effects, and spacecraft attitude. Deliverables include a final report of our work and a prototype software package that finds a fuel-optimal path from low earth orbits to geosynchronous orbits.

ViaSat, Inc.: Analysis and Implementation of an Elliptic Curve Cryptography Scheme for Asymmetric Key Exchange

Advisor
Weiqing Gu

ViaSat, Inc. is interested in using cryptography to provide secure communication solutions to their clients. In the first phase of this project, elliptic curve crptography (ECC) was reviewed and compared to several alternatives. ECC has many merits, justifying its pursuit. The research in phase I of the project also provided some guidelines for performing elliptic curve cryptography efficiently. This phase, phase II, will focus on furthering the ideas gathered in phase I, and culminate in the development of a prototype algorithm for elliptic curve key generation and recommendation for key-exchange protocols.
