Bayesian methods of astronomical source extraction [PDF]
, 2007 We present two new source extraction methods, based on Bayesian model selection and using the Bayesian Information Criterion (BIC). The first is a source detection filter, able to simultaneously detect point sources and estimate the image background. The

Modeling the elastic strain fields by point-source method
Advanced Engineering Research, 2015 The aim is to study the efficiency of numerical models of elastic stress fields in deformed solids. The field point-source method (PSM) designated as the method of fundamental solutions (MFS) in the foreign literature is used when creating these models ...

Accurate detection method of pig's temperature based on non‐point source thermal infrared image
CAAI Transactions on Intelligence Technology, 2021 Body temperature measurement is a very important task in the sow breeding process. The authors used an infrared camera to detect the temperature of the body surface of the sows, relying on calculating the average of the infrared image temperature in the ...

Method for calculating non-point source pollution distribution in plain rivers
Water Science and Engineering, 2011 The land area in a river network is divided into certain-scale square cells for the sake of precision, and, based on the physical mechanisms of rainfall-runoff processes and runoff pollution, the non-point source pollution from cells is estimated using ...

Motion parameter estimation of multitonal sources with a single hydrophone [PDF]
JASA Express Letters, 2021 In this letter, a method is proposed to estimate the motion parameters of a multitonal source with a single hydrophone when only the acquisition time of the pressure field is known.

P-resonant control for the neutral point of three phase inverter [PDF]
, 2014 In this project, a Proportional resonant (PR) current controller is proposed to maintain a balanced neutral point for a three-phase four wire inverter, which can be used in microgrid applications. The neutral-point circuit consists of a conventional

Superresolution method for data deconvolution by superposition of point sources
CoRR, 2018 Title was changed to clarify that it is a single acquisition method and the sources superposed are virtual. We add a new example of the two straight segments synthesize an artificial image.
