Fair Isaac Corporation

Visualizing Proof Search

Liaisons: John Byrnes
Advisor: Robert Keller
Students: Mike Buchanan (PM-F), Michael Ernst, Phil Miller (PM-S), Chris Roberts

Fair Isaac deals with large knowledge bases in a variety of their lines of business. They are developing an automated theorem prover in the natural deduction framework to build on these data sets. The scale of the proofs and their attendant search spaces make textual proof display and analysis of the prover’s operation unreasonable. Thus, the Clinic team has developed a visualization system which greatly eases development efforts. It provides a structured display of the theorem prover’s search space and a programmable command-line interface which gives the developer significantly more flexibility than a conventional debugger would allow.

CPU and GPU Based Image Processing for Digital Photographers

Liaisons: Brad Hinkel ’84, Eric Bennett
Advisor: Z Sweedyk
Students: Lucy Abramyan (PM), Morgan Conbere, Ellen Kephart, Lilia Markham, Matt McKenett

Through over a century of research and practice, professional film photographers developed visual aesthetics for compelling images, with “looks” pleasing to the human eye. These techniques are often at odds with the non-perceptual, analytical image processing algorithms applied to digital photographs today. This project examines how these worlds can be united by developing aesthetically-inspired algorithms and prototypes (on the CPU and GPU) for perceptual saturation enhancement, soft focus simulation, and locally-modified high-dynamic range image processing.

QUALCOMM

The On-Board Inert Gas Generating System (OBIGGS) is an important part of an aircraft’s on board fuel supply safety system. Due to complex geometries presented by fitting the system in the aircraft’s wings, it is possible for the distribution system to dip into a fuel tank, allowing fuel to entrain in the pipes. This clinic project tests the effectiveness of the OBIGGS System in clearing entrained fuel by simulating geometries and conditions found in an aircraft.

Lawrence Livermore National Laboratory

Optimizing a Water-Based Muon Detector

Liaison: Steven Dazeley
Advisor: Erik Spjut
Students: Ben Stanphill (TL), Bertrand Achard, Lupita Bermudez, Danny Lim (S), Justin White (F)

The LLNL Clinic team is experimenting with changing various design parameters of a water-based muon detector. When muons pass through water, they give off Cherenkov radiation, which is mostly in the ultraviolet (UV) range. Cherenkov radiation is very dim, so Photomultiplier Tubes (PMTs) are used to detect it. Unfortunately, PMTs do not detect UV radiation well. The team is testing a variety of methods to increase the detection rate of muons.

This project is a feasibility study on the design of an image stabilization system with a significant increase in performance over any existing system.

Space Systems/Loral

Low-Shock Solution for Satellite Solar Array Deployment

Liaisons: Mark Zanella, Gerrit Van Ommering
Advisor: Clive Dym
Students: Casey Schilling (TL), Mike Chan, Michael Crockett, Noel Godinez, Daniel Rodriguez (F)

Current Space Systems/Loral satellites are powered by solar arrays that are initially folded and secured against the side of the satellite by pretensioned rods. Upon reaching orbit, knives driven by small explosive charges cut each rod, allowing for solar array deployment. However, the sudden release of the tension in the rods produces undesirable shock. The team has been asked to design a lower-shock alternative to the current retention and release design.

SRI International

Ad-Hoc In-Building Tracking System

Liaisons: Tony Hawkins ’01, Gary Okerson ’95, John Shockley, Jonathan Solnit
Advisor: Joseph King
Students: Matthew Weiner (TL), Jeff Jones (F-TL), Eric Burkhart, Nitin Savant, Eric Young (F)

GPS-based tracking has become commonplace, but it is of little value in areas where the GPS signals are not sufficiently reliable to get an accurate position, such as inside buildings. To overcome this shortfall, the team has created a dead reckoning tracking system that can locate an individual indoors without any previous knowledge of the building or preexisting infrastructure. The system uses ultrasonic ranging to find the distance and direction of each of the user’s footsteps.

Advisor: Darryl Yong ’96
Consultant: Weiqing Gu
Students: Logan Gordon, Martin Hunt (PM), Maria Pavlovskaia (S), Trang Pham (F), Will Tipton

It is often faster and more convenient to digitize physical documents using photographs from digital cameras rather than scanners. However, such photographs suffer from perspective distortion, bends and folds in the documents and other imperfections. The Clinic team designed and implemented algorithms that can correct these distortions. The team’s system automatically dewarps photographs of documents to improve the readability of the images for both humans and computers.

WorldQuant, LLC

Efficient Stock Trading

Liaisons: Jeff Miller ’98, Brian Johnson ’98
Advisor: Susan Martonosi
Students: Greg Borish, Jason Christiansen (PM), Alex Korn, Minal Shankar

Hedge funds often trade thousands of shares of a stock each day. Market impact and liquidity con-straints make it a poor financial decision to execute these large trades in a single order. Rather, it is wise to split the order into several small orders to minimize costs. The purpose of this project is to develop and test an algorithm which will efficiently split large orders to obtain the best average price over all shares traded.

Southwest Research Institute

Modeling the Performance of a Jupiter Bound Electron Sensor in Strong Magnetic Fields

Liaisons: Frederic Allegrini, Craig Pollock
Advisors: Ellis Cumberbatch (CGU), Vatche Sahakian
Students: Kathleen Eliseo (PM-F), Maxsim Gibiansky (PM-S), Joshua Kao, Ethan Rubin (F), Rocio Ruelas (PM-S), Mariam Youssef

In August of 2011, NASA will launch the satellite Juno to conduct an in-depth study of the planet Jupiter. On board the satellite there are three electrostatic analyzers (ESAs) that will measure the energy and trajectory direction of electrons in Jupiter’s auroras. The behavior and performance of ESAs is well understood in the absence of a magnetic field. It was the task of this Clinic team to account for the effect of these magnetic fields. The team ran computer simulations of the ESAs in magnetic fields of varying magnitude and direction. Mathematical models were then devised for the energy of the electrons and their incoming angle relative to the direction of the magnetic field. These models can be used to translate the data that will be collected by the ESAs into a map of the spectrum of the electrons near Jupiter.
