This paper reports intrusion detection using distributed acoustic sensors based on phase- sensitive enhanced Rayleigh scattering optical time-domain reflectometry. Vibration data induced by human locomotion was analyzed by convolution neural networks and achieve over 76.25% accuracy on human identification.
Use spectrometers to monitor high explosive (HE) events in infrared region: Spectrometers measure radiance in many (100s) of spectral bands; Sensors give information on the fireball such as temperature, size, soot quantity and gas species concentrations (CO, CO₂, H₂O, etc.).

In subsurface flow modeling, quantifying the uncertainty of model parameters and the corresponding uncertainly on output quantities is a crucial task for groundwater management. Markov chain Monte Carlo (MCMC) methods can take advantage of observed data to estimate parameters in a Bayesian setting. However, MCMC can be slow to converge and produce highly correlated samples when the dimensions of the parameters is high. Using gradients for the posterior distribution can help samplers explore the parameter space more efficiently, but obtaining gradients can be computationally challenging.
