We present results from laboratory experiments of the downslope propagation a finite volume released gravity current by means combined PIV/PLIF measurements. The experimental data were used to estimate global characteristics current, such as speed, lateral surface and buoyancy, revealing that thermal theory is robust model can predict quantities properly, especially models Beghin et al. (1981),...

Density-based clustering algorithms are widely used for discovering clusters in pattern recognition and machine learning. They can deal with non-hyperspherical robust to outliers. However, the runtime of density-based is heavily dominated by neighborhood finding density estimation which time-consuming. Meanwhile, traditional acceleration methods using indexing techniques such as KD-tree may not...

abstract field experiment was carried out at the ferdowsi university research field, mashhad, iran during 2006-2007, to determine how much effective the n-fertilization is, to find out the most suitable plant density which could be used in chamomile (matricaria chamomilla l. asteraceae) to increase the yield of anthodium flowers and content of essential oil. the experimental design was as two f...

background: the advances in treatment regimes for thalassemic patients have increased the survival among them therefore osteoporosis has emerged as an important cause of morbidity. the aim of this study was to determine the prevalence of osteoporosis and osteopenia in patients with thalassemia from zafar adult thalassemia clinic, tehran, iran. patients and methods: in this cross sectional inves...
