This paper describes the successful development and demonstration of a Laser Fault Injection (LFI) technique to inject soft, i.e., transient, faults into VLSI circuits in a precisely-controlled, non-destructive, non-intrusive manner for the purpose of validating fault tolerant design and performance. The technique described in this paper not only enables(More)
– A simplified analysis is presented for controller design of small scale helicopters for non-aggressive flight scenarios. A MATLAB based detailed approach was followed to analyze the mathematical characteristics of the system, and to aid the design process of PID/PD and fuzzy logic controllers for the yaw, the pitch, the roll (Euler angles) and the height(More)
This paper proposes a light-weight online classification method to detect smarthpone user's postural actions, such as sitting, standing, walking, and running. These actions are named as “user states” since they are inferred after the analysis of data acquired from the smartphones equipped accelerometer sensors. To differentiate one user state(More)
This paper presents a novel framework that includes an inhomogeneous (time-variant) Hidden Markov Model (HMM) and learning from data concepts. The framework either recognizes or estimates user contextual inferences called `user states' within the concept of Human Activity Recognition (HAR) for future context-aware applications.
