OBJECTIVE To evaluate the accuracy of body mass index (BMI) as a predictor of body fat in elderly women. RESEARCH METHODS AND PROCEDURES A total of 1423 women aged 67 +/- 5 (mean +/- SD, range: 60 to 88) years were consecutively enrolled into the study. Fat mass (FM) was measured using DXA. RESULTS BMI explained 72.9% of FM variance (p < 0.0001), with a root mean square error of estimate (R...
modeling and forecasting the volatility of tehran exchange dividend price index (tedpix) the present research, analyses the forecasting performance of a variety of conditional and non-conditional models of tedpix volatility at the daily frequencies performance criterion namely the root mean square error (rmse). under rmse, results show ma250 and cgarch models had better performance between non ...

Drying of spruce, beech, willow, and alder sawdust was examined in a laboratory type dryer. The effect drying air temperature T (25, 60, 80 °C) airflow velocity v (0.01, 0.15, 1.5 m/s) investigated. obtained results demonstrated that have impacts on the sawdust. experimental dehydration data were fitted to theoretical, semi-theoretical, empirical thin-layer models. accuracies models estimated u...
An evacuated tube solar collector drier is designed and developed to study analytically and experimentally drying kinetics of Thompson seedless grapes in Pune, India. Drying experiments are carried out in the month of April- June for continuous three years from 2013-2015. During the experimentation, temperatures of hot and cold air at various places, ambient relative humidity and humidity varia...
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 ...
1.1 introduction “i see translation as the attempt to produce a text so transparent that it does not seem to be translated. a good translation is like a pane of glass. you only notice that it’s there when there are little imperfections- scratches, bubbles. ideally, there shouldn’t be any. it should never call attention to itself.” “norman shapiro” (venuti, 1995:1) edward fitzgerald is the br...
The aim of this study was to provide detailed information on rationales, calculations, and results of common methods used to quantify reproducibility in plantar pressure variables. Recreational runners (N=95) performed multiple barefoot running trials in a laboratory setup, and pressure variables were analyzed in nine distinct subareas of the foot. Reproducibility was assessed by calculating in...
â abstract: in this paper, artificial neural network (ann) was used for modeling the nonlinear structure of a debutanizer column in a refinery gas process plant. the actual input-output data of the system were measured in order to be used for system identification based on root mean square error (rmse) minimization approach. it was shown that the designed recurrent neural network is able to pr...
