I lead a research group on Dependable Distributed and Networked SystemsThe group works on the foundations of fault-tolerance, security, and timeliness properties,   develops design, verification, and implementation methods,   and builds prototypes of dependable systems for new application areas. 

We are especially interested in discovering new methods for scalable dependability,  as well as in characterizing the differences between reasoning about system correctness versus reasoning about systems dependability. Our methods draw from the theory of self-stabilization, and exploit formal specifications of and "white box" knowledge about the system. Demonstrations of our work are presently focused on embedded sensor network applications and internet services.

James W. Davis, Dept. of Computer Science and Engineering, is developing an advanced video surveillance system that uses computers equipped with video cameras to not only detect the presence of people and track them, but also to identify their activities. The research has broad implications for Homeland Security as well as search and rescue, border patrol, law enforcement and many other types of military applications. The system combines video cameras with machine learning methods, enabling the computer to perform the kind of visual recognition that seems effortless for humans. Davis' work in investigating computer vision methods was recognized by the National Science Foundation with the prestigious NSF Faculty Early Career Development (CAREER) Program award. Support for this research (past and present) has been provided by the National Science Foundation, U.S. Air Force, Los Alamos National Lab, U.S. Army Night Vision Laboratory, Intel, and Ohio Board of Regents.

Machiraju's research and technical publications deal with volume rendering, imaging and parallel rendering. Specifically, he is interested in examining issues of accuracy and adaptivity in volume rendering and imaging. Techniques from both classical interpolation and sampling theory and the more recent wavelet theory have been used towards this end. Ongoing work includes wavelet based volume rendering techniques and image comparison metrics. His other research interests include biomedical imaging and high performance computing.

Research Interests: Stochastic digital signal processing; spectral estimation; time series analysis; parameter estimation; statistical properties of algorithms; array signal processing. Applications to automatic target recognition and sensor networks. Most of this research is conducted with colleagues and students in the Information Processing Systems (IPS) Laboratory. Current research efforts include:

  • Feature extraction for automatic target recognition (ATR) from radar signals; ATR performance analysis.
  • Self-localization of sensor networks.
  • Object detection and tracking using sensor networks.
