On the Replica of US Pulmonary Artifacts by Means of Physical Models [PDF]

open access: yesDiagnostics, 2021
Currently, the diagnostic value of the artefactual information provided by lung ultrasound images is widely recognized by physicians. In particular, the existence of a correlation between the visual characteristics of the vertical artifacts, which arise ...

Use of liquid analog model in engineering hydrology training (precipitation-runoff model) [PDF]

open access: yesFanāvarī-i āmūzish, 2008
Proper training of hydrologists in the field of precipitation-runoff modeling can play a significant role in overcoming many flood problems. In this paper, after introducing the liquid analog model, it is established as a new analog model in the field of

Physical Modeling of the Piano [PDF]

open access: yesEURASIP Journal on Advances in Signal Processing, 2003
Over the past several years, this project has been aimed at constructing a physical model of the piano. The goal is to use Newton’s laws to describe the motion of the hammers, strings, soundboard, and surrounding air, and thereby calculate the sound produced by the instrument entirely from first principles.

Lung Ultrasound Artifacts Interpreted as Pathology Footprints

open access: yesDiagnostics, 2023
Background: The original observation that lung ultrasound provides information regarding the physical state of the organ, rather than the anatomical details related to the disease, has reinforced the idea that the observed acoustic signs represent ...
