Extension of the distributed point source method for ultrasonic field modeling. [PDF]
Ultrasonics, 2011 The distributed point source method (DPSM) was recently proposed for ultrasonic field modeling and other applications. This method uses distributed point sources, placed slightly behind transducer surface, to model the ultrasound field. The acoustic strength of each point source is obtained through matrix inversion that requires the number of target ...

Time-dependent point source search methods in high energy neutrino astronomy [PDF]
Astroparticle Physics, 2010 We present maximum-likelihood search methods for time-dependent fluxes from point sources, such as flares or periodic emissions. We describe a method for the case when the time dependence of the flux can be assumed a priori from other observations, and we additionally describe a method to search for bursts with an unknown time dependence.

Uncovering neutrinos from cosmic ray factories: the Multi Point Source method [PDF]
Astroparticle Physics, 2013 We present a novel method for the search of high energy extraterrestrial neutrinos in extended regions. The method is based on the study of the spatial correlations between the events recorded by neutrino telescopes.

Development of point source method and its practical significance
Water Science and Engineering, 2009 The advantages of Reichardt's hypothesis in dealing with single and multiple circular jets in a stagnant environment are highlighted. The stages involved in the development of the point source method, an offshoot of the new hypothesis, are presented ...

Agricultural Non-Point Source Pollution: Comprehensive Analysis of Sources and Assessment Methods [PDF]
AgricultureAgricultural non-point source pollution (ANPSP) significantly affects worldwide water quality, soil integrity, and ecosystems. Primary factors are nutrient runoff, pesticide leaching, and inadequate livestock waste management. Nonetheless, a thorough assessment of ANPSP sources and efficient control techniques is still lacking. This research delineates

A Bayesian method for point source polarisation estimation [PDF]
Astronomy & Astrophysics, 2021 The estimation of the polarisation P of extragalactic compact sources in cosmic microwave background (CMB) images is a very important task in order to clean these images for cosmological purposes –for example, to constrain the tensor-to-scalar ratio of primordial fluctuations during inflation– and also to obtain relevant astrophysical information about
