For any algebraic curve C and n ≥ 1, P. Etingof introduced a ‘global’ Cherednik algebra as a natural deformation of the cross product D(Cn)⋊Sn, of the algebra of differential operators on Cn and the symmetric group. We provide a construction of the global Cherednik algebra in terms of quantum Hamiltonian reduction. We study a category of character Dmodules on a representation scheme associated ...

The Curve Number (CN) rainfall–runoff model is a widely used method for estimating the amount of rainfall and runoff, but its accuracy in predicting runoff has been questioned globally due to failure produce precise predictions. was developed by United States Department Agriculture (USDA) Soil Conservation Services (SCS) 1954, data documentation about development are incomplete, making it diffi...

This study calibrated the Soil Conservation Service Curve Number (SCS-CN) model to predict decadal runoff in Peninsula Malaysia and found a correlation between reduction of forest area, urbanization, an increase volume. The conventional SCS-CN was commit type II error this must be pre-justified with statistics before being adopted for any prediction. Between 1970 2000, deforestation caused decl...

Permeable Pavement (PP) models are valuable tools for studying the implementation of PPs in urban environments. However, runoff simulated by traditional such as Curve Number (CN) is different from that created with PP models, infiltration computed differently. many investigations compare both to extract broader conclusions without considering how two related. Hence, this research explores relat...

(a) The curves z(s) and z(s, t) were not required to be simple curves. This made the task of approximating them with continuously differentiable curves very easy. (b) The Cauchy integral theorem also holds if the function z(s) describing the curve C is merely piecewise continuously differentiable. For in this case we carry out the integration by parts in (6) over each subinterval on which zs(s)...

HEC HMS merupakan salah satu aplikasi pemodelan yang dapat digunakan untuk memodelkan nilai limpasan harian maupun bulanan berdasarkan karakteristik DAS. Tujuan penelitian ini adalah 1) Mengkaji fisik DAS Serang direpresentasikan oleh curve number (CN) 2) aliran berupa debit puncak, volume outflow, dan waktu puncak dari hidrograf banjir terukur dengan hasil menggunakan HEC-HMS. Nilai CN ditentu...

The use of geographic information systems (GISs) and remote sensing to facilitate the estimation of runoff from watershed and agricultural fields has gained increasing attention in recent years. This is mainly due to the fact that rainfall-runoff models include both spatial and geomorphologic variations. The US Department of Agriculture, Natural Resources Conservation Service Curve Number (USDA...

The Benanain Watershed is located in East Nusa Tenggara with an area of 3,181 km2 and divided into 29 sub-watersheds. itself eastern region Indonesia a unique climate condition called semi-arid. high rainfall intensity occurring short duration results large surface runoff erosion. Floods erosion semi-arid areas due to sensitive soils drought heavy extremely. This paper presents the application ...

The study of a curve from the arithmetical or the Arakelov viewpoints is a hard task, since it involves a very good knowledge of its geometry (differential forms, periods), its arithmetic (locus of bad reduction, stable models) and its analysis (Green function). Classically, two families of curves have been extensively studied: Fermat curves and modular curves. The study of these curves is feas...
