Water phenomena are some of the most visually spectacular effects found in nature. This paper presents a novel efficient hybrid method to model turbulent water such as fast flowing rivers and waterfalls with the intent that the model can be used as part of a larger environment or scene. The model presented uses hydrostatic theory to incorporate a 2D height field and a particle system to model r...

In Peninsular Malaysia, a large proportion of malaria cases occur in the central mountainous and forested parts of the country. As part of a study to assess remote sensing data as a tool for vector mapping, we conducted entomological surveys to determine the type of mosquitoes, their characteristics and the abundance of habitats of the vector Anopheles maculatus in malaria endemic areas in Pos ...

mixed layer is a part of the atmospheric boundary layer in which pollutants are uniformly distributed. it is sensitive to the earth’s surface, controls the flow of heat and momentum between the surface and the free atmosphere, thus playing a key role in atmospheric circulation. most of atmospheric pollution models require the height of the mixed layer as an input to determine the depth of atmos...

Athyrium haleakalae K.R. Wood & W.L. Wagner (Athyriaceae), a small lithophytic fern from East Maui, Hawaiian Islands, is described and illustrated. Notes on its distribution, ecology, and conservation status are also presented. The new species appears to be an obligate rheophyte, preferring sites of fast moving water along concave walls of streams and waterfalls. Athyrium haleakalae differs fro...

In this article, three new green's functions are presented for a narrow strip line (not a thin wire) inside or on a homogeneous dielectric, supposing quasi-TEM dominant mode. These functions have no singularity in contrast to so far presented ones, so that they can be used easily to determine the capacitance matrix of multi-layer and single-layer homogeneous coupled microstrip lines. To obtain ...

The genus Vestalenula is the most species rich in the putative ancient asexual ostracod Family Darwinulidae. Several new Recent species were described from various continents, mostly based on carapace shape and structure. These species were found in a variety of aquatic and (semi-) terrestrial habitats, including springs, streams, interstitial waters, leaf litter in forests and in splash zones ...

We develop a method that o¤ers consistent and computationally e¢ cient credit risk analysis of cash‡ow CDO structures. The proposal makes use of simple portfolio models that admit semi-analytic representations of the loss distribution, combined with detailed and fast calculations of realistic interest and principal cash‡ow waterfalls. We de…ne in this context and study credit tranche risk measu...

Ranid frogs of the genus Amolops occur in Southeast Asia and are typically found near waterfalls. Their phylogenetic relationships have not been resolved. We include 2,213 aligned nucleotide sites of the 12S, 16S and tRNAval gene regions of the mitochondrial DNA genome from 43 individuals of Chinese and Vietnamese Amolops, Huia, Hylarana, Meristogenys, Odorrana and Rana. The outgroup species we...

Abstract Visual conditions around Palaeolithic sites determine how the landscape was perceived by prehistoric hunter-gatherers. By placing site in different landscapes, visual foci were encoded locational characteristics of places. For Early Ahmarian Levant, it can be shown that differ significantly with combination large ungulate prey exploited at respective location. A Higuchi viewshed approa...
