Analysis of Os-Cfar and Ml-Cfar for a detection of a target in a noisy environment

, 2023
The purpose of this work is to address the problem of detection in an inhomogeneous environment with clutter distributed in a homogeneous way for two types of detectors the OS and the ML-CFAR. The clutter is assumed to be a sea clutter represented by a Weibull distribution.

The use of activated carbon derived from spent coffee grounds as a reusable, sustainable, and effective solution for the removal of butylparaben from water

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Parabens, including butylparaben (BP), are widely used as antimicrobial preservatives in food, cosmetics, and pharmaceuticals, yet are poorly removed by conventional water treatment processes and pose potential risks to aquatic life and human health.

Trajectories of medication for opioid use disorder and their impact on HIV testing among people who inject drugs in India: A longitudinal assessment of clinic‐based data

Addiction, Volume 120, Issue 4, Page 745-755, April 2025.
Abstract Aims The aim of this study was to identify longitudinal trajectories of medication for opioid use disorder (MOUD) use throughout 1 year following MOUD initiation and to examine the association of trajectory membership with HIV testing among people who inject drugs in India.

An Efficient CFAR Detector for Burr Type-XII Distributed SAR Ground Clutter

IEEE Access
In this paper, a CFAR target detection algorithm is proposed for Burr TypeXII-distributed Synthetic Aperture Radar (SAR) ground clutter amplitude data. We employ method of log-cumulants (MoLC) to estimate the clutter model parameters.
