PURPOSE To compare the outcome of photorefractive keratectomy (PRK) and complications in patients treated with either loteprednol etabonate 0.5% gel or prednisolone acetate 1% suspension and fluorometholone (fml) 0.1% suspension. SETTING John A Moran Eye Center, University of Utah, Salt Lake City, UT, USA. DESIGN Prospective, randomized, partially masked trial. METHODS PRK was performed o...

The cylindrical shell is a widely used structure in engineering practice, and its main form of failure instability due to buckling. As classical problem the field mechanics, stability shells has been studied extensively. However, large difference between theoretically predicted results critical buckling load experimental for subjected uniform axial pressure contributed continuous development th...

Abstract— The present study is devoted for the development of a mathematical model to predict the structural behavior and critical pressure of composite cylindrical shell under external pressure using finite element analysis. The composites can be tailored to match the external loading. The effect of fibre orientation angle along with stacking sequence of the composites on the loading carrying ...

Notice that this is a much simpler function (e.g., no logs), and it is clear that the discrepancy between the obtained covariance matrix and the covariance matrix implied by the model (S-Σ) is minimized after weighting it by W. Although any W can be chosen for the weight matrix, most commonly, the inverse of the covariance matrix, S, is used in SEM packages. FGLS is asymptotically equivalent to...

The first half of this paper introduces the aim of SAIBA and the functional markup language (FML) from the perspective of the Center for Analysis and Design of Intelligent Agents (CADIA) at Reykjavik University. The second half provides a brief historic overview of the functional representation of communicative intent in a line of communicative humanoids and related systems, starting with Ganda...

In this study, the structural reliability of plate-stiffened prismatic pressure vessels was analyzed over time. A analysis performed using a time-dependent method based on response surface (RSM). The vessel had rectangular cross-section with repeated internal load-bearing structures. For analysis, structure modeled as strip, and to identify changes in index when general corrosion pitting occurr...
