رسوب گذاری در رودخانه ها و مقایسه معادلات انتقال رسوب van-rign _ackers and white _ yang
در این تحقیق مبانی نظری تحقیق و معادلات و روابط موجود شرح داده شده است و یک مدل عددی که توانایی شبیه سازی میدان حل را با روابط فوق را داشته باشد انتخاب شده است. نرم افزار ssiim 2.0 که نرم-افزاری قدرتمند با توانایی شبیه سازی سه بعدی میدان جریان و رسوب برای این مهم انتخاب گردید. برای بررسی معادلات پدیده انتقال رسوب با استفاده از نرم افزار فوق برای حالات و سازه های مختلف هیدرولیکی که در رودخانه اس...
Ambulatory activity and body mass index in white and non-white older adults.
BACKGROUND The purpose of this study was to examine the extent to which physical activity (PA) is related to obesity in older adults when accounting for race/ethnicity. METHODS Cross-sectional data were collected on 214 older adults (72.3 +/- 8.9 y; body mass index [BMI] 28.9 +/- 6.0; 151 females; 96 non-White). Measures of body height and mass were collected; BMI was calculated. PA was asses...
متن کاملImmigration concern and the white/non-white difference in smoking: Group position theory and health
National data indicate that U.S. whites have a higher prevalence of smoking compared to non-whites. Group position theory and public opinion data suggest racial differences in immigration concern. This study examines whether immigration concern mediates the racial difference in smoking. Drawing on the 2012 General Social Survey, the 2012 American National Election Study, and the 2006 Portraits ...
متن کاملResting energy expenditure in white and non-white severely obese women.
This study aimed to compare the resting energy expenditure (REE) of white and non-white severely obese Brazilian women. REE was examined in 83 severely obese Brazilian women (n = 58 white and 25 non-white) with mean (+/- SD) age 42.99 +/- 11.35 and body mass index 46.88 +/- 6.22 kg/m(2) who were candidates for gastric bypass surgery. Body composition was assessed by air displacement plethysmogr...
متن کاملPhase-shifting interferometry corrupted by white and non-white additive noise.
The standard tool to estimate the phase of a sequence of phase-shifted interferograms is the Phase Shifting Algorithm (PSA). The performance of PSAs to a sequence of interferograms corrupted by non-white additive noise has not been reported before. In this paper we use the Frequency Transfer Function (FTF) of a PSA to generalize previous white additive noise analysis to non-white additive noisy...
