Statistical Estimation of Fluid Flow Fields
Many natural phenomena involve dynamic fluids whose motion differs radically from that of rigid bodies. This paper presents a novel approach for estimating fluid motion fields. It first estimates a local flow probability distribution function at each pixel using the STAR model and the data from a spatio-temporal neighborhood. It then feeds the set of distribution functions into a global optimiz...
متن کاملGraphic representation of electrocardiographic leads by means of fluid mappers.
A new method for the studyof electrocardiographic leads is described. It makes use of plaster models having the same shape as the body in the frontal (or other) planes through which water flows in sheets. The flow of water is approximately analogous to the flow of electric currents through the body, and the flow lines are made visible by small crystals of soluble dye. If fluid passes in and out...
متن کاملTopological Analysis of Nerves, Reeb Spaces, Mappers, and Multiscale Mappers
Data analysis often concerns not only the space where data come from, but also various types of maps attached to data. In recent years, several related structures have been used to study maps on data, including Reeb spaces, mappers and multiscale mappers. The construction of these structures also relies on the so-called nerve of a cover of the domain. In this paper, we aim to analyze the topolo...
متن کاملInfluence of Geological Structures on Fluid and Heat Flow Fields
Geothermal exploration is commonly performed in the absence of 3-D seismics or other high quality methods constraining the geometry of the underlying geological system. Therefore, uncertainty resides in the structural model itself. This is in addition to the usual assumption of stochasticity in the petrophysical properties. We show here that small changes in the geometrical description of the g...
