چکیده
We consider the problem of recovering the coeecient q(x) in the equation u t = u ? qu from boundary observations. Uniqueness of q based on knowledge of thèNeumann 7 !Dirichlet response operator' is shown as an implication of (known) corresponding results concerning the inverse problem for the corresponding hyperbolic equation w tt = w ? qw. This is then reduced to use of the response to a single input with some consideration of computational approximation.

Monitoring of SO2 column concentration over Iran using satellite-based observations during 2005-2016
For the first time, sulfur dioxide concentration was monitored between 2005 and 2016 over Iran which is among the countries with a high SO2 emission rate in the world. To that end, SO2 column concentration at Planetary Boundary Layer (PBL) from Ozone Monitoring Instrument (OMI) was analyzed. OMI is a sensor onboard the Aura satellite which can measure daily SO2 concentration on the global scale...
متن کاملGravity acceleration at the sea surface derived from satellite altimetry data using harmonic splines
Gravity acceleration data have grand pursuit for marine applications. Due to environmental effects, marine gravity observations always hold a high noise level. In this paper, we propose an approach to produce marine gravity data using satellite altimetry, high-resolution geopotential models and harmonic splines. On the one hand, harmonic spline functions have great capability for local gravity ...
متن کاملIdentification of q ( x ) in u t = ∆ u − qu from boundary observations 1
We consider the problem of recovering the coefficient q(x) in the equation ut = ∆u− qu from boundary observations. Uniqueness of q based on knowledge of the ‘Neumann 7→Dirichlet response operator’ is shown as an implication of (known) corresponding results concerning the inverse problem for the corresponding hyperbolic equation wtt = ∆w − qw. This is then reduced to use of the response to a sin...
متن کاملInvestigating the topography effect in modeling of deformation field of CampiFlegrei volcano using the method of fundamental solution
Considering the importance of predicting volcano eruption and the large number of volcanic peaks across the world, having enough researches in this field is vital. Based on geodetic researches, surface deformation of the earth in the form of uplift or subsidence in the volcanic region, is an indicator of the magma's movement respectively towards the crater or the exit from the tank around. In...
متن کاملMeasuring the Five-Parameter Grain-Boundary Distribution from Observations of Planar Sections
A stereological method is described for estimating the distribution of grain-boundary types in polycrystalline materials on the basis of observations from a single planar section. The grain-boundary distribution is expressed in terms of five macroscopically observable parameters that include: three parameters that describe the lattice misorientation across the boundary and two parameters that d...
