Sustainable Water through Innovation in Membranes & Materials (SWIMM)
(Virginia Tech, 2017-05-15)
Water scarcity is mainly caused by overwhelming human consumption and contamination, from production of water-thirsty meats and vegetables, biofuel crop production, industrial uses, and rapid urbanization. The scale of ...
Reducing Model-Form Uncertainty in Simulations of Turbulent Flows: From Data Assimilation to Machine Learning
ANASYS Uncertainty Quantification Workshop. (Invited Lecture, 1.5 hours).
Friction Studies – From Passive to Intelligent Tires
Keystroke-Dynamics Authentication Against Synthetic Forgeries
We describe the use of keystroke-dynamics patterns for authentication and detecting infected hosts, and evaluate its robustness against forgery attacks. Specifically, we present a remote authentication framework called ...
Social Turing Tests: Crowdsourcing Sybil Detection
(Internet Society, 2013-02)
As popular tools for spreading spam and malware, Sybils (or fake accounts) pose a serious threat to online communities such as Online Social Networks (OSNs). Today, sophisticated attackers are creating realistic Sybils ...
A Declarative Approach to Hardening Services Against QoS Vulnerabilities
The Quality of Service (QoS) in a distributed service-oriented application can be negatively affected by a variety of factors. Network volatility, hostile exploits, poor service management, all can prevent a service-oriented ...
Personal Anomaly Detection and Smart-Phone Security
(Virginia Tech, 2010-04-22)
Mobile devices increasingly become the computing platform for networked applications such as Web and email. This development requires strong guarantees on the system integrity and data security of mobile devices against ...
Designing for Schadenfreude (or, how to express well-being and see if youʼre boring people)
This position paper presents two studies of content not normally expressed in status updates—well-being and status feedback—and considers how they may be processed, valued and used for potential quality-of-life benefits ...
HOMER: An Interactive System for Home Based Stroke Rehabilitation
Delivering long term, unsupervised stroke rehabilitation in the home is a complex challenge that requires robust, low cost, scalable, and engaging solutions. We present HOMER, an interactive system that uses novel therapy ...
Rapid Screening of Transformed Data Leaks with Efficient Algorithms and Parallel Computing
The leak of sensitive data on computer systems poses a serious threat to organizational security. Organizations need to identify the exposure of sensitive data by screening the content in storage and transmission, i.e., ...
