Intentional tampering in the internal circuit structure by implanting Trojans can result in disastrous operational consequences. While a faulty manufacturing leads to a nonfunctional device, effect of an external implant can be far more detrimental. Therefore, effective detection and diagnosis of such maligned ICs in the post silicon testing phase is imperative, if the parts are intended to be used...
Present and future semiconductor technologies are characterized by increasing parameters variations as well as an increasing susceptibility to external disturbances. Transient errors during system operation are no longer restricted to memories but also affect random logic, and a robust design becomes mandatory to ensure a reliable system operation. Self-checking circuits rely on redundancy to detect...
In this paper, we propose an intelligent surveillance system which can detect human, recognize certain postures and activities, and send out informing SMS messages when abnormal activities are detected. Nine static postures can be recognized using universal eigenspace technique and projection histogram matching method. After recognizing static postures, Hidden Markov Models are used to recognize human...
