The common approach to radial distortion is by the means of polynomial approximation, which introduces distortion-specific parameters into the camera model and requires estimation of these distortion parameters. The task of estimating radial distortion is to find a radial distortion model that allows easy undistortion as well as satisfactory accuracy. This paper presents a new class of rational...

today, banks, as intermediaries, seek to attract and allocate resources to obtain greater benefit. therefore, the bank assessment is considered as an important subject in the banking industry. data envelopment analysis is an effective technique in evaluating the efficiency of decision-making units. there are factors among banking indices (such as receivables from resource allocation) that are i...

the hydration of biomolecules is vitally important in molecular biology, so in this paper thesolvation energy and radial distribution function of dna bases have been calculated by themonte carlo simulation.the geometries of isolated adenine, guanine, cytosine, and thyminehave been optimized using 6-31+g(d,p) basis function sets. these geometries then will be used inthe monte carlo calculation o...

in this article, non radial method of dynamic dea with the parallel network structure is presented and is used for calculation of relative efficiency measures when inputs and outputs do not change equally. in this model, dmu divisions under evaluation have been put together in parallel. but its dynamic structure is assumed in series. since in real applications there are undesirable inputs and o...

The radial stator of three-pole radial-axial hybrid magnetic bearings (HMB) has three magnetic poles and the three magnetic poles are driven by a three-phase converter, so the three-pole radial-axial HMB has the advantages of compact structure, low cost, low power consumption and so on. However, as the sum of three-phase current is zero and the three radial magnetic poles are asymmetric, the re...

in this paper, changes of casson non-newtonian fluid velocity profile, for different distribution of porosity, have been investigated. for distribution of porosity, fixed, radial and exponential variations has been considered. for all three states, brinkman model has been used as momentum equation. since the casson fluid is a good model for blood, this analysis can be used in studying about cho...
