Machine Vision for Detecting Water Droplets

Dr. Yan Tong has received a research grant award from the Electric Power Research Institute (EPRI) for "NSF-EPRI: Innovative and Ultra-efficient Evaporators to Realize Cost-effective Desalination”. This project aims to relieve the water-energy-food issues facing the US and the world by substantially reducing the cost of sea water desalination, making it possible to obtain massive freshwater from seawater. Yan's group will develop a fully automatic vision-based technique to detect droplets and to estimate the individual droplet departure frequency and size by non-rigid image registration and onsite-calibration. This vision-based technique is essential to reduce massive data from high-speed optical images to assure a consistent data reduction process.

It is Possible to Hack a Phone With Sound Waves

This NY Times article describes research by Dr Wenyuan Xu and colleages at the University of Michigan into how to maliciously control a phone's accelerometer using sound waves.
In their paper, the researchers describe how they added fake steps to a Fitbit fitness monitor and played a "malicious" music file from the speaker of a smartphone to control the phone’s accelerometer. That allowed them to interfere with software that relies on the smartphone, like an app used to pilot a radio-controlled toy car.
The video below explains their research.

Dr. Wang Receives NSF Award for Design Reconstruction Algorithm

Dr. Song Wang has received a research grant award from the National Science Foundation for his project entitled "Algorithm Development for Reconstruction of Design Elements". This is an interdisciplinary study between archaeology and computer science to develop and disseminate a program that can identify the full artistic design from fragmented cultural heritage objects. Specifically, it will develop the algorithm to identify the designs of the carved wooden paddles of the Southeastern Woodlands from unearthed pottery sherds. Research also described in USC News: Fingerprints to the past. Image from

  • Dr. Valtorta Receives Grant Award for Probabilistic Reasoning

    Dr. Marco Valtorta has received an award from the Intelligence Advanced Research Projects Activity (IARPA) to work on the Co-Arg: Cogent Argumentation System with Crowd Elicitation project, lead by George Mason University. This project aims to improve the quality of intelligence analysis reports. Dr. Valtorta's work will develop a probabilistic reasoning component to complement the Wigmorean argument structures used as the main representation in the Co-Arg project. Argument structures will be translated into Bayesian networks, thus uncovering subtleties and complexities, such as evidence-induced dependencies, synergistic effects, and antagonistic effects, which will be resolved by analysts or via crowdsourcing.

    Dr. Terejanu Receives Grant Award from the NIDA/USDA

    Dr. Gabriel Terejanu has received a research award from the National Institute of Food and Agriculture (NIFA)/USDA for his project, "TOXIMAP: Computational Framework for Prediction of Geographical and Temporal Incidence of Mycotoxins in US Crop Fields". This project will develop a general predictive modeling framework for calculating aflatoxin occurrence in US crop fields before harvest, and package this knowledge in a user-friendly predictive web/mobile interface for generating nation-wide and real-time aflatoxin hazard maps. This project has the potential to change certain behaviors in crop management to improve food safety.

    Dr. Gregory Gay Receives NSF Grant for Software Testing

    Dr. Gregory Gay has received an NSF Research award for his project on Understanding The Role of Software Test Adequacy Criteria in Search-Based Test Generation. This work aims to help improve automated software testing in industry. Abstract Software testing ensures that software is robust and reliable. As testers cannot know what faults exist apriori, dozens of metrics---ranging from the measurement of structural coverage to the detection of synthetic faults---have been proposed to judge test case adequacy. In theory, if such metrics are fulfilled, tests should be adequate at detecting faults. To alleviate the high cost of testing, optimization algorithms can be used to automatically generate test suites. These adequacy metrics are well-suited for guiding automated test creation. However, there is no adequacy metric known to universally correspond to "effective fault detection." Testers are left with a bewildering number of testing options, and there is little guidance on when to use one criterion over another. These metrics are a solid starting point for test case generation. Many faults cannot be detected until the code has been executed. However, merely executing code does not ensure adequate testing. How code is executed is important. It is clear that testers do not yet understand which adequacy metrics actually correspond to a high probability of fault detection, or under what situations these metrics can be applied. Therefore, it is clear that improving automated test generation requires gaining a better understanding of the circumstances where particular metrics are effective, isolating the features of such metrics that correlate to fault detection in such circumstances, and establishing and evaluating guidelines for the use and combination of metrics - perhaps tied to particular system types or domains - that will result in real-world fault detection. Large-scale empirical investigations will be performed into the nature of the relationship between adequacy criteria and the probability of fault detection in order to understand the efficacy and applicability of the criteria that are used to guide test creation. This work will have broader impacts on industrial practices, software engineering education, and - through dissemination to and collaborations with industrial partners and regulatory agencies - public safety and security.

    Student Report from Black Women in Computing Conference

    The inaugural Black Women in Computing Conference (BWIC) was held on January 6-8, 2017 at Howard University in Washington D.C. The theme of the conference was, “Honoring our past, celebrating our present, and looking into our future.” BWIC provided a venue to discuss, advance, and celebrate the intersectionality of race and gender in computing. The conference committee had the goals of catalyzing community between black women in computing, nurturing personal and professional growth, and discussing salient themes facing the group in society. Speakers ranged from North Carolina State’s Dr. Fay Cobb Payton, to White House representative Lisa Gelobter, to image activist Michaela angela Davis. Karina Liles, a PhD candidate in computer science, and De’Aira Bryant, an undergraduate senior in computer science, attended the conference on behalf of the University of South Carolina’s College of Engineering and Computing. Liles is a graduate student advisor for the Minorities in Computing at USC student group and Bryant is the current president of the group.
    "We discussed pivotal issues such as intersectionality, tokenism, and imposter syndrome—many of which I didn’t realize were issues facing the community, but rather just the way life worked for black women in computing. The open and enlightening conversations are ones that I still reflect upon today. For example, I learned that self-care and wellness are just as important as work deadlines. It’s not always worth, “getting degreed to get diabetes and die.

    The community of women were extremely honest and inspiring in their experiences. I marveled at the presence of women who looked like me that had taken similar life paths—and had been successful. I am extremely grateful to the department for allowing me to experience this historical conference and gain so much from it. As I look to complete my final semester of undergrad at USC, I could not have asked for a better way to start it."
