In this paper we present methods for triangulation of infinite cylinders from image line silhouettes. We show numerically that linear estimation a general quadric surface is inherently badly posed problem. Instead propose to constrain the conic section circle, and give algebraic constraints on dual conic, models manifold. Using these derive fast minimal solver based three silhouette lines, can ...

By using Euler-Maclaurin's summation formula and the way of real analysis, a more accurate multipleHilbert-type inequality and the equivalent form are given. We also prove that the same constantfactor in the equivalent inequalities is the best possible.

This study was conducted with the purpose of examining Persian speakers’ article acquisition and use with reference to Ionin, Ko and Wexler’s (2004) model, which is based on the prediction of Fluctuation Hypothesis (FH) that EFL learners of [-article] languages, like Persian, make erroneous article use in [+definite, -specific] and [-definite, +specific] contexts. From among the students of an ...

When a detector sensitive to the target plume IR seeker is used for tracking airborne targets, the seeker tends to follow the target hot point which is a point farther away from the target exhaust and its fuselage. In order to increase the missile effectiveness, it is necessary to modify the guidance law by adding a lead bias command. The resulting guidance is known as target adaptive guidance ...

The development of numerical techniques now permits us to analyze complex structures such as dielectric resonator filters and planar passive elements for coplanar monolithic microwave integrated circuits. In this paper, we describe a novel method for designing dielectric resonator filters. Then a Chebychev band pass filter is designed by coaxially placing high-Q TM01Q dielectric resonators ...

Although the random sum distribution has been well-studied in probability theory, inference for the mean of such distribution is very limited in the literature. In this paper, two approaches are proposed to obtain inference for the mean of the Poisson-Exponential distribution. Both proposed approaches require the log-likelihood function of the Poisson-Exponential distribution, but the exact for...

there are a number of techniques available to estimate saturated-liquid molar or specific volumes or densities of liquids. in this study, a new empirical correlation is presented to calculate volume of saturated liquids as a function of critical volume, reduced temperature and acentric factor. an optimization algorithm is utilized to obtain unknown parameters of this correlation by fitting them...
