Advisor: Z Sweedyk
Students: Erin Coughlan (PM), Meredith Murphy, Haakon Saxberg, Michael Stock-Matthews
Amazon in OC would like to improve the customer experience with mobile apps on the Kindle Fire and other Android devices by adding in-app commenting. The HMC Clinic team has developed an API that allows mobile app developers to easily integrate with social networks. Customers can now read comments left by their friends while running the app―at a line in a book, a scene in a movie, or a level in a game―as well as leave their own comments.
Automated Candidate Sourcing
Liaisons: Charles Swan, Sabreen Lakhani ’11, Colin Bodell
Advisor: Melissa O’Neill
Students: Zachary Purdy (PM), Rai Feren, Joseph Dearden, Josh Oratz
Amazon.com needs to hire talented software engineers to maintain and develop their online software services. The industry-standard processes for finding candidates miss many strong developers and are time-consuming for Amazon’s recruiters. The goal of this project is to create a tool that improves the efficiency and breadth of Amazon’s candidate search by intelligently mining online resources.

Optimizing SSD Performance for OneFS Workloads
Liaisons: Steve Hubbell ’95, Ben Melhuish ’94
Advisor: Geoff Kuenning
Students: David Ersek, Brad Jensen (PM-S), Stephen Levine (PM-F), Matthew Prince
Isilon recently began offering storage nodes that incorporate solid-state disks (SSDs). Although SSDs differ significantly from hard drives, they employ a flash translation layer that allows them to be treated as hard drives. However, SSDs still have very different optimal access patterns. We developed methods for optimizing writes to SSDs in Isilon’s OneFS file system.
Mobile Document Image Processing
Liaisons: Kurt Rapelje, Ryan Wong, Ed Heaney ’04
Advisor: Z Sweedyk
Students: Jason Yu (PM), Jordan Ezzell, Nick Kinkade, Ben Normoyle
Laserfiche provides content management solutions that include software to digitize and process documents. One capability of Laserfiche’s software is to process images of documents taken with a smartphone camera so they look as if they were scanned. Our goal is to improve the algorithm in this process so that background artifacts and border noise are removed and document text is straightened.
An Open-Source System for Malware Detection
Liaison: Dan Drew
Advisor: Geoff Kuenning
Students: My Diem Ho (PM), Josiah Gaskin, Alex Eng, Lawrence Thibodeaux
Proofpoint, Inc. offers Security-as-a-Service to companies of medium to large size and is dedicated to protecting sensitive information from outside threats such as malware. They asked our Clinic team to develop a system to detect attacks carried in innocent-seeming files. We constructed a system from existing open-source components that can detect suspicious Microsoft Office and Rich Text Format documents by analyzing files statically. The system examines the files for malformed content and structure, and flags suspicious material for more detailed analysis by a sandboxing system.

Advisor: Robert Keller
Students: Jordan Librande (PM), Jacob Bandes-Storch, Jay Jonsson, Michael Morton
The Atomistic-to-Continuum software package (AtC), developed by Sandia National Laboratories, couples the modeling techniques of Molecular Dynamics and Finite Element Analysis in order to simulate a wide variety of complex nanoscalesystems. Our goal was to increase the parallel performance of AtC, thereby making larger simulations more computationally feasible in multicore environments. To this end, we designed and implemented parallel matrix multiplication algorithms and distributed Finite Element data and calculations across processors more intelligently.
A User Interface for VMware’s VProbes Software
Liaisons: Ricardo Gonzalez, Radu Rugina, Avi Shai
Advisor: Christopher A. Stone
Students: Amelia Nybakke, Max Kukartsev (PM-S), Milo Toor, Sarah Johnson (PM-F)
VMware, Inc. is a leading developer of virtual machine technology. In order to diagnose software running within the virtual setting, VMware provides a script-based instrumentation technology called VProbes. However, this technology has a steep learning curve and requires the user to be familiar with the underlying system of VMware’s software. In our Clinic project we made VProbes accessible to non-programmers by exposing some of its common functionality via a web-based user interface.
Walt Disney Animation Studios
Interactive Documentation Collaboration System
Liaisons: Dan Candela, Chuck Tappan, Lawrence Chai ’88/89
Advisor: Robert Keller
Students: Beryl Egerter, Julius Elinson (PM), Jessica Hester, August Toman-Yih
Artists and developers at Walt Disney Animation Studios work with rapidly evolving internal software and complex commercial packages. Staying current with new features, best practices, and studio-specific workflows can be challenging. Users frequently have questions about software capabilities or discover aspects that would be useful to their colleagues. However, there formerly was no effective means of making inquiries or sharing such information. We have developed CPlane, a program that will enable users to create and share this documentation easily.

Advisors: Kash Gokli, Erik Spjut
Students: Martha Cuenca (TL-S), Carlo Vaccari (TL-F), Alyssa Siegman, Mia Cooledge (S), Kevin Lau (S), Angela Medina (S), Anthony Chung (F), Victoria Feudo (F)
SternoCandleLamp is the nation’s #1 chafing fuel supplier. Their liquid chafing fuel cans are selfcontained standalone fuel sources designed to keep food at safe temperatures in chafing dishes. These cans are usually discarded after one use and not recycled. Additionally, the cost of the can constitutes a large portion of the product’s overall production cost. To address these issues, the team designed a means to reduce chafing fuel can waste without compromising current product performance, while also minimizing lifecycle cost.
Cold Flow Model of a Fluidized Bed Reactor
Liaison: Kevin Mills, PE
Advisor: Mary Cardenas
Students: Matthew Kweon (TL-S), Ilona Phipps-Morgan (TL-F), Sydney Hanson, Monica Hwang, Edward Ruan, Alexandra Wright (S)
Fluidized bed reactors convert carbonaceous solids to syngas, with minimal environmental impacts.

Advisor: John Molinder
Students: Trevor Apple (TL-S), Matt Goodwin (TL-F), Parker Martin, Diana Mar (S), Douglas Hu (F), Brett Mills (F)
Most antennas with wideband range and high directionality are three dimensional in shape, with spiral and bicone antenna geometries as notably useful and common examples. A three dimensional shape makes antennas non-ideal for aerospace applications. Trivec Avant asked the Clinic team to develop a planar, ultra-wideband antenna (225MHz-2000MHz) with return loss below -5dB and directivity at azimuth above -6dBi across the entire frequency band.
Intel Corporation with Technion University, Israel

Analyzing the Effects of Market Legislation on Market Behavior
Liaison: Andy Niedermaier ’04
Advisor: Weiqing Gu
Students: Devin Bowers (PM), Matt Johnson, Jeehyun Kim, Matt Toal
Recent events have prompted the Securities and Exchange Commission to institute new regulations to prevent extreme market behavior. These regulations take effect for short periods of time when individual securities rapidly change in price. However, the impact of these regulations on market behavior has not yet been extensively studied. Our project is to apply quantitative techniques on high-frequency market data to determine the impact of these rules on securities.

Optimizing Drilling Rate with Machine Learning
Liaisons: Xianping (Sean) Wu
Advisor: Rachel Levy
Students: Kyle Chakos, Sam Gray, Xanda Schofield (PM), John Wentworth
Shell E&P spends millions of dollars every day on offshore drilling operations. To monitor this process, a substantial amount of drilling data is collected and transmitted to an onshore operations center in real time.

Manual Meter Reading Cost Minimization
Liaisons: Brad Davis, Rick Jefferson, Ron Johnson, Gary Mgeryan, Hugo Rimbert
Advisor: Lisette DePillis
Students: Ben Gross, Katarina Hoeger (PM), Kevin Varela-O’Hara, Tim Yee
Southern California Gas (SCG) Company is converting manually read meters to automated meters, obviating the need for employees to visit and read gas meters in person. As clusters of meters throughout Southern California become automated over time, the number of remaining manually read meters will diminish until all meters have become automated. Our team is developing a tool that uses the locations of the remaining manually read meters to generate new cost-minimizing meter reading routes.
