The Model Based Fault Tolerant Control (MBFTC) task was conducted under the NASA Aviation Safety and Security Program. The goal of MBFTC is to develop and demonstrate real-time strategies to diagnose and accommodate anomalous aircraft engine events such as sensor faults, actuator faults, or turbine gas-path component damage that can lead to in-flight shutdowns, aborted take offs, asymmetric thrust/loss of thrust control, or engine surge/stall events. A suite of model-based fault detection algorithms were developed and evaluated. Based on the performance and maturity of the developed algorithms two approaches were selected for further analysis: (i) multiple-hypothesis testing, and (ii) neural networks; both used residuals from an Extended Kalman Filter to detect the occurrence of the selected faults. A simple fusion algorithm was implemented to combine the results from each algorithm to obtain an overall estimate of the identified fault type and magnitude. The identification of the fault type and magnitude enabled the use of an online fault accommodation strategy to correct for the adverse impact of these faults on engine operability thereby enabling continued engine operation in the presence of these faults. The performance of the fault detection and accommodation algorithm was extensively tested in a simulation environment.

Is Army and civilians only used as vote bank or a comfort tool of politician? Why do politicians never actually answer the questions they've been asked? Why do politician use the martyrdom of an army for the power of their chair? Why no one arise questions to politicians about solider's martyrdom? After all, how long will women continue to fight for their basic rights? These are the questions which need to be asked with each and every so called representives of our country...... Welcome to 'No Candle Use Sandal,' a story about Shankara and his love, family, and his concern about world youth problem. Love marriages always have its own stories but a solider's love marriage and their obstacles are beyond the imagination. In this book a solider have their own set of question about the love, about the ones who are against
