in many industrialized areas, the highest concentration of particulate matter, as a major concern on public health, is being felt worldwide problem. since the air pollution assessment and its evaluation with considering spatial dispersion analysis because of various factors are complex, in this paper, gis-based modeling approach was utilized to zoning pm2.5 dispersion over tehran, during one ye...

PURPOSE In the present project, the virtual reconstruction of digital osteomized zygomatic bones was simulated using different methods. MATERIALS AND METHODS A total of 15 skulls were scanned using computed tomography, and a virtual osteotomy of the left zygomatic bone was performed. Next, virtual reconstructions of the missing part using mirror imaging (with and without best fit registration...

We repeat our previous calculation about the effect of the spin-orbit-induced magnetic anisotropy on the Kondo temperature in the case of S = 5/2 impurity spin which is quite different from the integer spin case as the ground state is degenerated. In this case the Kondo contribution remains finite when the sample size goes to zero and the thickness dependence in the Kondo resistivity is much mo...

While direct theorems for interpolation with radial basis functions are intensively investigated, little is known about inverse theorems so far. This paper deals with both inverse and saturation theorems. For an inverse theorem we especially show that a function that can be approximated sufficiently fast must belong to the native space of the basis function in use. In case of thin plate spline ...

We suggest a method of fitting of the zero-range model of the tectonic plate under the boundary stress based on comparison of the theoretical formulae for the corresponding eigenfunctions/eigenvalues with the results of instrumental measurements of frequency and the shape and the shape of the relevant seismo-gravitational modes in the remoted zone. Comparison of the data of the instrumental mea...

There have been many studies and much attention paid to spatial sharpening for thermal imagery. Among them, TsHARP, based on the good correlation between vegetation index and land surface temperature (LST), is regarded as a standard technique because of its operational simplicity and effectiveness. However, as LST is affected by other factors (e.g., soil moisture) in the areas with low vegetati...

A new form of thr~-dimensioM1 crystals of the 50 S ribosomal subunits from Haiobacterium m~~mortui has been obtained at 19”C, using ~iyethyle~e glycol in the presence of 1.2-1.7 M KC1 in the crystall~tion mixture. The crystals diffract X-rays to 13 A and are stable in the synehrotron radiation beam for 4-8 h. Being aggregates of thin plates, the dimensions of only two unit cell edges, 147 x 181...

Vector field approximation is a problem involving the reconstruction of physical fields from a set of scattered observed data. In this paper, we address the problem of interpolation of divergence-free vector fields in three dimensional space by thin plate spline under tension. The problem is formulated as a minimization problem where the cost is related to the equilibrium energy of thin plate w...

Image registration (IR) aims to geometrically match one image to another. It is extensivelyused in many imaging applications. Among many existing IR methods, one widely used group ofmethods are feature-based. By a feature-based method, a number of relevant image features arefirst extracted from the two images, respectively, and then a geometric matching transformationis found to...
