Prediction of Binder Content in Glass Fiber Reinforced Asphalt Mix Using Machine Learning Techniques
Several researchers have reported the results of adding a variety fibers to asphalt concrete described as fiber-reinforced (FRAC). This research paper finds most suitable prediction model for Marshall Stability and optimistic bitumen content useful in glass mix by performing tests further analyzing data consonance with published research. Four machine learning approaches were used find best i.e...
The purpose of this study was to describe growth curve in Baluchi sheep by application of nonlinear growth models. The weight records of 1228 and 676 Baluchi male and female lambs for birth weight, one-month, two-month, three-month, four-month, six-month, nine-month and one year of age were studied. These data had been collected by Baluchi Sheep Breeding Center in Mashhad (Abbas Abad) during 20...
there are two major theories of measurement in psychometrics: classical test theory (ctt) and item-response theory (irt). despite its widespread and long use, ctt has a number of shortcomings, which make it problematic to be used for practical and theoretical purposes. irt tries to solve these shortcomings, and provide better and more dependable answers. one of the applications of irt is the as...
Yield forecasting is a rational and scientific way of predicting future occurrences in agriculture—the level production effects. Its main purpose reducing the risk decision-making process affecting yield terms quantity quality. The aim following study was to generate linear non-linear model forecast tuber three very early potato cultivars: Arielle, Riviera, Viviana. In order achieve set goal st...
This paper aims at evaluating volatility forecasts for the US Dollar/Mauritian Rupee exchange rate obtained via a GARCH (1,1) model under two distributional assumptions: the Generalized Error Distribution (GED) and the Student’s-t distribution. We make use of daily data to evaluate the parameters of each model and produce volatility estimates. The forecasting ability is subsequently assessed us...
this study is an outlook of iranians religious practices and customs in eras such as nasser one. it attempts to answer the main question, "religious practices and ceremonies in the society during naseri ruling" and other subsidiary questions with scientific and historical theories. iran was a traditional and religious community . people abided by their religious practices and duties within reli...
abstract assessing moisture in the soil under cultivation of crops to achieve high performance and reduced water are necessary. knowledge of the moisture distribution in the root zone, time consuming and costly field tests that simulation models, a suitable alternative in answer to issues of movement and are water distribution. in this study assessment of soil moisture, to aid swap simulation m...
In this study, an air heated solar collector (AHSC) dryer was designed to determine the drying characteristics of the pear. Flat pear slices of 10 mm thickness were used in the experiments. The pears were dried both in the AHSC dryer and under the sun. Panel glass temperature, panel floor temperature, panel inlet temperature, panel outlet temperature, drying cabinet inlet temperature, drying ca...
This study developed an IPCC (Intergovernmental Panel on Climate Change) compliant method for the estimation of above-ground carbon (AGC) in forest stands using remote sensing technology. A multi-level morphological active contour (MMAC) algorithm was employed to obtain tree-level metrics (tree height (LH), crown radius (LCR), competition index (LCI), and stem diameter (LDBH)) from an airborne ...
