Raman spectroscopy (RS) has shown great potential in noninvasive cancer screening. Statistically based algorithms, such as principal component analysis, are commonly employed to provide tissue classification; however, they are difficult to relate to

We developed a biophysical Raman model of human skin and validated it using in vivo clinical screening data. Key biophysical changes were used for fast and accurate diagnosis of melanoma and nonmelanoma skin cancer.

Restricted Boltzmann Machines (RBMs) have been developed for a lot of applications in the past few years, and many of its variants have also appeared. In this paper, RBM model and its learning algorithm with contrastive divergence algorithm will be i

Precise GPS velocity and acceleration determination relies on Doppler and/or Doppler rate observations. There are no direct Doppler rate measurements in GPS. Although every GPS receiver measures Doppler shifts, some receivers output only "raw" Dopple

Over-the-horizon radar systems are capable of localizing targets in range and azimuth but are unable to achieve reliable altitude estimation. Past work has shown that the time-varying Doppler signatures of micro-multipath signals provide rich informa

Over-the-horizon radar (OTHR) systems provide wide-area surveillance capabilities to detect and track targets far beyond the range of conventional line-of-sight radars. Because of the narrowband waveforms, OTHR systems do not achieve reliable altitud

Sequential Monte Carlo particle filters (PFs) are useful for estimating nonlinear non-Gaussian dynamic system parameters. As these algorithms are recursive, their real-time implementation can be computationally complex. In this paper, we analyze the

We investigate two methods for estimating the matched signal transformations caused by time-varying underwater acoustic channels in orthogonal frequency division multiplexing (OFDM) communication systems. The underwater acoustic channel for this 12

A key challenge in real-world structural health monitoring (SHM) is diversity of damage phenomena and variability in environmental and operational conditions. Conventional learning techniques, while adequate for moderately complex inference tasks, ca
