نصب منابع پراکنده در سیستم های توزیع و فوق توزیع علاوه بر مزیت های فراوان، مشکلاتی را هم به همراه دارد. یکی از این مشکلات تأثیر این منابع روی اندازه جریان های اتصال کوتاه است. به طور معمول از حفاظت های مبتنی بر اصل جریان زیاد در سیستم های توزیع و فوق توزیع استفاده می شود. از مهمترین طرح های حفاظتی استفاده شده در فیدرهای توزیع، حفاظت فیوز- ریکلوزر است. همچنین از طرح های حفاظتی جریان زیاد جهتی در...

the takmeh-dash region comprises a wide variety of igneous bodies that have been developed from early to late neogen. the granitic rocks and related aplite apophyses have been developed along fault-dominated structures which defines a well pronounced mineralized zone. according to isotopic and fluid inclusion studies, most of the quartz-pyrite units are solution-related with some traces of cu, ...
the problem of hypothesis testing with a nuisance parameter is considered. two methods forusing fuzzy knowledge on the nuisance parameter to test hypotheses are suggested. these methods areneither a pure classical nor a pure bayesian approach to hypothesis testing, but rather related to both. afew known examples and their applications, which cannot be studied by the parametric statisticalmethod...
scott and szewczyk in technometrics, 2001, have introduced a similarity measure for twodensities f1 and f2 , by1, 21 21 1 2 2( , ), ,f fsim f ff f f f< >=< >< >wheref1, f2 f1(x, θ1)f2(x, θ2)dx.+∞−∞< >=∫sim(f1, f2) has some appropriate properties that can be suitable measures for the similarity of f1 and f2 .however, due to some restrictions on the value of parameters and the kind of densities, ...
The on-axis intensity distribution, or the Strehl ratio versus defocus, is described in a phase-space domain in terms of the Wigner distribution function. A coordinate transformation that is defined for a general annular aperture is employed to convert the pupil amplitude transmittance into a one-dimensional function. We show that the single display of the Wigner distribution function associate...
The development of retention prediction models for the seven ginsenosides (Rf, Rg1, Rd, Re, Rc, Rb2 and Rb1) on a polyvinyl alcohol (PVA)-bonded stationary phase at subambient temperatures is presented. The models were derived using multiple linear regression (MLR) and artificial neural network (ANN) using the logarithm of the retention factor (log k) as the dependent variable. Using stepwise M...
PURPOSE To determine the configuration of the anterior lamina cribrosa (LC) surface in eyes with different tilt axes. METHODS A total of 114 eyes (66 glaucomatous eyes and 48 healthy eyes) with tilted optic discs (ovality index > 1.3) were divided into vertical- and horizontal-tilt groups according to their optic disc tilt axis. Serial horizontal B-scan images of the ONH were obtained from ea...
PURPOSE We evaluated the prevalence and characteristics of the defects of the lamina cribrosa (LC) in high myopia and glaucoma, and compared them with control eyes using swept-source optical coherence tomography (SS-OCT). METHODS One hundred fifty-nine eyes of 108 participants were divided into four subgroups; high myopia with glaucoma (MG, 67 eyes of 46 subjects), glaucoma without high myopi...
PURPOSE To investigate the difference between two-dimensionally measured disc diameters (DDs) based on fundus images and three-dimensionally measured DDs based on enhanced depth imaging optical coherence tomography (EDI-OCT). METHODS The DDs were three-dimensionally measured on EDI-OCT images of optic nerve heads and two-dimensionally measured on near-infrared reflectance fundus images in 90 ...
