Prof. Necmiye Ozay, assistant professor of Electrical and Computer Engineering, was awarded a NASA Early Career Faculty award for her project, “Run-time anomaly detection and mitigation in information-rich cyber-physical systems.” Her research will be designed to assist in future missions in space, while being applicable to a wide range of cyber-physical systems.

Next generation space missions require autonomous systems to operate without human intervention for long periods of times in highly dynamic environments. Such systems are vulnerable to software and/or hardware failures due to unexpected internal or external factors. Moreover, small anomalies, if not detected and isolated in a timely manner, can cascade through the system resulting in catastrophic outcomes, especially in highly dynamic missions where fail safe is not an option. This signifies the need for effective methods for integrated system health management, automated data analysis for decision making and verification and validation.

The objective of this project is to develop the scientific foundation and associated algorithmic tools for synthesis of decentralized passive and active monitors for sensor-rich networked cyber-physical systems from heterogeneous sensory data.

The potential benefits of the proposed research include (i) reductions in the design time of next generation space systems by automating synthesis of monitoring algorithms instead of hand-coded built-in tests, (ii) reductions in system cost by the potential to replace hardware redundancy with software-based solutions, (iii) increase in the time systems operate reliably by enabling timely detection of anomalies and reducing their cascading effects.

Prof. Ozay plans to demonstrate the techniques she and her team develops on two university-scale testbeds: (i) vehicular energy networks, and (ii) human-robot teams for exploration missions with limited communication.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
