We report root-mean-square (RMS) wavefront error (WFE) for individual aberrations and cumulative high-order (HO) RMS WFE for the normal human eye as a function of age by decade and pupil diameter in 1 mm steps from 3 to 7 mm and determine the relationship among HO RMS WFE, mean age for each decade of life, and luminance for physiologic pupil diameters. Subjects included 146 healthy individuals ...
We propose four methods for finding local subspaces in large spectral libraries. The proposed four methods include (a) cosine angle spectral matching; (b) hit quality index spectral matching; (c) self-organizing maps and (d) archetypal analysis methods. Then evaluate prediction accuracies for global and subspaces calibration models. These methods were tested on a mid-infrared spectral library c...
The goal of present experiments is to investigate the use of multiple kernel learning as a tool for pricing options in the context of Indian stock market for Nifty index options. In this paper, fair price of an option is predicted by Multiple Kernel Support Vector Regression (MKLSVR) using linear combinations of kernels and Single Kernel Support Vector Regression (SKSVR). Prices of option highl...
BACKGROUND This study aims to analyze the active pharmaceutical ingredients (APIs) of licorice (Radix Glycyrrhizae; gancao), including glycyrrhizic acid, liquiritin, isoliquiritin and total flavonoids, in multi-ingredient and multi-phase extraction by online near-infrared technology with fiber optic probes and chemometric analysis. METHODS High-performance liquid chromatography and ultraviole...
Color, phenolic content, and chemical age values of red wines made from Cretan grape varieties (Kotsifali, Mandilari) were evaluated over nine months of maturation in different containers for two vintages. The wines differed greatly on their anthocyanin profiles. Mid-IR spectra were also recorded with the use of a Fourier Transform Infrared Spectrophotometer in ZnSe disk mode. Analysis of Varia...
The prediction of stock price movement direction is significant in financial circles and academic. Stock contains complex, incomplete, fuzzy information which makes it an extremely difficult task to predict its development trend. Predicting analysing data a nonlinear, time-dependent problem. With rapid machine learning deep learning, this can be performed more effectively by purposely designed ...
In this paper, a set of Root mean square derivative based closed Newton Cotes quadrature formula (RMSDCNC) is introduced in which the derivative value is included in addition to the existing closed Newton Cotes quadrature (CNC) formula for the calculation of a definite integral in the inetrval [a, b]. These derivative value is measured by using the root mean square value. The proposed formula y...
در این تحقیق با استفاده از خشک کن آزمایشگاهی جابه جایی هوای داغ، خشک کردن ورقه ای نازک برش های سیب زمینی، مدل سازی گردید. هدف از این پژوهش، بررسی سینتیک خشک کردن و ارائه ی مدل ریاضی مطلوب سیب زمینی با استفاده از آنالیز معادله ی رگرسیون بود. آزمایش ها در دو سطح دمایی 65 و70 درجه ی سانتیگراد در سه تکرار، انجام گردید. سه مدل ریاضی سینتیکی استاندارد بر داده های تجربی برازش داده شد و ارزیابی مدل ها ...
