PulsePath: Two-Stage Generative Waveform Refinement for Robust Remote Photoplethysmography Estimation [PDF]
SensorsRemote photoplethysmography (rPPG) estimates pulse signals from facial videos, but motion, illumination variation, exposure control, and compression can distort the waveform used for heart-rate (HR) estimation. The Plane-Orthogonal-to-Skin (POS) waveform

An Exponentiated Multivariate Extension for the Birnbaum-Saunders Log-Linear Model
Mathematics, 2022 In this work, a bivariate extension of the univariate exponentiated sinh-normal distribution is proposed. The properties of the new distribution, which is called the bivariate exponentiated sinh-normal distribution, are studied in detail, and the maximum

TWO-STAGE DEA ESTIMATION OF TECHNICAL EFFICIENCY: COMPARISON OF DIFFERENT ESTIMATORS [PDF]
Review of Agricultural and Applied Economics, 2022 Research background: The challenge of resource limitations requires that farmers make judicious use of resources to maximize output and profit levels. This can be achieved through assessment of resource-use efficiency of farmers by estimating the level ...
