This research describes the goals, design and implementation of a quasi natural gradient, laboratory scale, sand tank (aquifer) model experiment. The model was used to study the transport of an inorganic tracer (Chloride) in groundwater, within a tropical aquifer (porous medium) material. Three-dimensional sand tank (1.8 m × 0.3 m × 0.8 m) experiments were conducted to investigate contaminant t...

due to the scarcity of water resources, the need for sustainable development of drip irrigation tape is essential in iran. a number of drip irrigation tape systems used in sugar beet fields of isfahan and chahar mahal va bakhtiari provinces were evaluated and were compared with furrow irrigation methods in two consecutive years. the actual water use efficiency (wuesy, wuewsy) in lower quarter, ...

It can be proved that 1/N ≤ DN ≤ 1 and 1/(2N) ≤ D∗ N ≤ DN ≤ 2D∗ N . The sequence X is uniformly distributed in [0, 1) if and only if limN→∞DN(X) = 0. We are interested in low-discrepancy sequences, that is, sequences X for which DN(X) is small for all N . The efficient construction of such X is essential in quasi-Monte Carlo algorithms used, for example, to approximate a multivariate integral o...

Sir, ‘References’ in an article includes the list of articles, books or the communications that have been referred to/consulted in presenting the document. They provide the source of the information being quoted in the article. The International Committee of Medical Journal Editors (ICMJE) has created the Uniform Requirements, primarily to help authors and editors in their mutual task of creati...

A quantitative model capturing pattern density effects in Deep Reactive Ion Etch (DRIE), which are important in MEMS, is presented. Our previous work has explored the causes of wafer-level variation and demonstrated die-to-die interactions resulting from pattern density and reactant species consumption. Several reports have focused on experimental evidence and modeling of feature level (aspect ...
