Journal ArticleDOI
Cutting force-based real-time estimation of tool wear in face milling using a combination of signal processing techniques
TL;DR: In this article, three different strategies based on linear filtering, time-domain averaging and wavelet transformation techniques are adopted for extracting relevant features from the measured signals, and the best features are identified on the basis of a statistical model selection criterion.
Journal ArticleDOI
Neural solution to the multitarget tracking data association problem
Debasis Sengupta,Ronald A. Iltis +1 more
TL;DR: Computer simulations indicate the ability of the joint probabilistic data association algorithm to track many targets simultaneously in the presence of moderately dense clutter.
Journal ArticleDOI
Log-concave and concave distributions in reliability
Debasis Sengupta,Asok K. Nanda +1 more
TL;DR: In this paper, the authors consider the class of log-concave distributions and the subclass of concave distributions, and examine the closure of these classes under a number of reliability operations, and provide sharp reliability bounds for nonmaintained and maintained units having life distribution belonging to these classes.
Journal ArticleDOI
Efficient estimation of parameters for non-Gaussian autoregressive processes
Debasis Sengupta,Steven Kay +1 more
TL;DR: A maximum-likelihood estimator is proposed for more precise estimation of the parameters of these processes coupled with a realistic non-Gaussian model for the driving noise.
Journal ArticleDOI
The National Center for Health Statistics reference and the growth of Indian adolescent boys
TL;DR: The NCHS reference data seem inadequate for this sample of adolescent boys from West Bengal, India, and consideration should be given to developing appropriate reference data based on healthy adolescent populations from different ethnic groups.
