In this paper, we study the problem of convergence of geodesics on PL-surfaces and in particular on subdivision surfaces. More precisely, if a sequence (Tn)n∈N of PL-surfaces converges in distance and in normals to a smooth surface S and if Cn is a geodesic of Tn (i.e. it is locally a shortest path) such that (Cn)n∈N converges to a curve C, we want to know if the limit curve C is a geodesic of ...

Photolysis of ICN at 281.5, 266 and 249 nm produces CN X '2+ fragments in which the population of the F,(J"= N''+;) and F2(J"= "'-4) finestructure components vary markedly as a function of d', N" and dissociation wavelength. Population differences favour either F1 or F2, and can be > 2: 1. A model is proposed to explain this behaviour, in which out-of-plane, spin-dependent forces cause the elec...

In the present article we study the asymptotic behavior of the sums n≤x cn+1 pn+1 − cn pn and n≤x pn+1 cn+1 − pn cn , and of the series ∞ n=1 cn+1 pn+1 − cn pn α , where p n denotes the n-th prime number while c n stands for the n-th composed number.

Flood prediction is very important in land and water resources management. Many flood disasters could be mitigated with adequate preparedness especially urban watershed. This study assessed the runoff potential of Opa watershed Southwest Nigeria using remote sensing Soil Conservation Service or SCS curve number (CN) techniques. The 2007 NigSat image year was classified into different cover clas...

An urban watershed in Xiamen was selected to perform the parameter uncertainty analysis for urban stormwater runoff modeling in terms of identification and sensitivity analysis based on storm water management model (SWMM) using Monte-Carlo sampling and regionalized sensitivity analysis (RSA) algorithm. Results show that Dstore-Imperv, Dstore-Perv and Curve Number (CN) are the identifiable param...

A major structural inconsistency of the traditional curve number (CN) model is its dependence on an unstable fixed initial abstraction, which normally results in sudden jumps in runoff estimation. Likewise, the lack of pre-storm soil moisture accounting (PSMA) procedure is another inherent limitation of the model. To circumvent those problems, we used a variable initial abstraction after ensemb...

The NRCS-CN method, integrated with GIS and remote sensing, can be used for estimating curve numbers (CN) surface runoff in geohydrological systems. study area is divided into 63 sub-basins, the land use cover (LULC)-hydrologic soil group (HSG) complex identified each sub-basin. CN values three antecedent moisture (AMC) conditions are calculated corrected slope variations. depth determined usin...

We introduce a novel parametric representation called ROPN (Random Offset Parametric representation with Noise), which is useful to represent a family of shapes sharing similar complex patterns often being able to be defined with the gradient noise functions. PORN is defined by replacing a static offset distance in a general offset with a gradient noise function. For example, PORN curve Cn(t) i...

[1] Motivated by the recent increasing availability of global remote sensing data for estimating precipitation and describing land surface characteristics, this note reports an approximate assessment of quasi-global runoff computed by incorporating satellite rainfall data and other remote sensing products in a relatively simple rainfall-runoff simulation approach: the Natural Resources Conserva...
