This article deals with the importance of simulation studies for reliability wind farm (WF) equipment during operation process. Improvements, upgrades, and introduction new solutions that change reliability, quality, conditions use present a research problem study. Based on this research, it is possible to continuously evaluate WF equipment. The topic testing complex technical facilities consta...

In this work, the fluid flow and mass transfer due to the presence of an electric field in a rectangular channel is examined. We consider a mixture of water or another neutral solvent and a salt compound, such as sodium chloride, for which the ionic species are entirely dissociated. Results are produced for the case in which the channel height is much greater than the electric double layer (EDL...

Moody’s adjusts a firm’s reported leverage across several dimensions to determine credit ratings. I find that changes to these adjustments affect firm capital structure and investment decisions, especially for firms near the investment grade boundary and with bond covenants containing ratings triggers. Further, in 2006, Moody’s made several changes to its adjustment methodologies. I find that c...

The structure of a two-phase steady detonation in a granulated solid propellant is studied, and existence conditions for a one-dimensional, steady two-phase detonation are given. Ordinary differential equations from continuum mixture theory are solved numerically to determine steady wave structure. In the limiting case where heat transfer and compaction effects are negligible, the model reduces...

Keywords: Supplementary variable technique Chapman–Kolmogorov Variable failure and repair rates Lagrange's method Runge–Kutta fourth order a b s t r a c t The purpose of this paper is to compute reliability of Polytube manufacturing plant having four units using supplementary variable technique. The failure and repair rates of the subsystems are variable. The mathematical equations are derived ...

Recent feminist and gender-oriented scholarship about the Victorian sonnet has attributed a pioneering role to Elizabeth Barrett Browning’s Sonnets from the Portuguese in the nineteenth-century revival of the genre. Eminent literary critics such as Angela Leighton, Alison Chapman, and Dorothy Mermin agree that theSonnets, in Chapman’s words, ‘translate the amatory discourse of Petrarchanism int...

The reconstruction of the vertical electrondensity pro®le is a fundamental problem in ionospheric tomography. Lack of near-horizontal ray paths limits the information available on the vertical pro®le, so that the resultant image of electron density is biased in a horizontal sense. The vertical pro®le is of great importance as it a€ects the authenticity of the entire tomographic image. A new met...

In this study, we investigated the Five-factor model in the concurrent prediction of positive symptom schizotypy as measured by the Magical Ideation (Eckblad & Chapman, 1983) and Perceptual Aberration (Chapman, Chapman, & Raulin, 1978) scales and negative symptom schizotypy as measured by the Physical Anhedonia (Chapman, Chapman, & Raulin, 1976) and Revised Social Anhedonia (Eckblad, Chapman, C...
