Four methodologies were evaluated for quantifying kilovoltage cone-beam computed tomography (CBCT) dose: the Cone-Beam Dose Index (CBDI), IAEA Report 5 recommended methodology (IAEA), the AAPM Task Group 111 methodology (TG111), and the current dose metric; the Computed Tomography Dose Index (CTDI) on two commercial Varian cone-beam CT imaging systems; the Clinac iX On-Board Imager (OBI); and t...

in this study, 160 fishes were randomly collected from commercial catch by a cone net in babolsar port from january to october 2010. the biological features of specimens were measured. 2 + years old fishes made the dominant age group with 33.75% and 1 + and 5 + years old had the least frequency (8.75%). relationship between length and weight indicated negative allometric growth pattern (b=2.581...

A sample of uniformly distributed unit vectors on an n-dimensional spherical cone is generated. The distances to a given limit state surface in the directions of the unit vectors of the sample are calculated and each of these distances are projected on the cone axis. The theoretical distribution of these projections is derived assuming the limit-state surface to be a hyperplane. This distributi...

the liquefaction resistance of soil can be evaluated using laboratory tests such as cyclic simple shear, cyclic triaxial, cyclic torsional shear as well as field methods like standard penetration test (spt), cone penetration test (cpt) and shear wave velocity (vs). in this regard, this study attempts to compare the results of the spt based on the simplified procedure proposed by seed and idriss...

in this paper, we introduce the cone normed spaces and cone bounded linear mappings. among other things, we prove the baire category theorem and the banach--steinhaus theorem in cone normed spaces.

We revisit the portfolio allocation problem with designated risk-budget. generalize of arbitrary risk budgets unequal correlations to one that includes return forecasts and transaction costs while keeping no-shorting constraint. offer a convex second order cone formulation scales well number assets explore solutions variants - on equity-bond asset problems as formulating portfolios using index ...

In this work, we define the notion of an algebraic distance in algebraic cone metric spaces defined by Niknam et al. [A. Niknam, S. Shamsi Gamchi and M. Janfada, Some results on TVS-cone normed spaces and algebraic cone metric spaces, Iranian J. Math. Sci. Infor. 9 (1) (2014), 71--80] and introduce some its elementary properties. Then we prove the existence and uniqueness of fixed point for a B...
