Shuttle radar topographic mission (SRTM) has created an unparalleled data set of global elevations that is freely available for modeling and environmental applications. The global availability (almost 80% of the Earth surface) of SRTM data provides baseline information for many types of the worldwide research. The processed SRTM 90 m digital elevation model (DEM) for the entire globe was compil...

Although many researchers have studied the flow hydraulics in compound channels, there are still many complicated problems in determination of their flow rating curves. Many different methods have been presented for these channels but extending them for all types of compound channels with different geometrical and hydraulic conditions is certainly difficult. In this study, by aid of nearly 400 ...

Numerical modeling was carried out to investigate the responses of suction bucket foundations under vertical cyclic loading. Numerical results were compared with centrifuge experiment results. Before the capacity of the model suction bucket to resist cyclic loading could be investigated, the static pullout capacities had to be determined. The buckets with different aspect ratio are investigated...

This paper reports the fabrication of a bulk micromachined hybrid torsional micromirror device composed of titanium mirror structures bonded to an underlying silicon sloping electrode structure. The fabrication of the device is enabled by two recent innovations: 1) the Metal Anisotropic Reactive Ion etching with Oxidation (MARIO) Process [1], which provides, for the first time, high aspect rati...

Forest soils belong to the major carbon sinks on Earth because of their high organic matter content. from Europe store approximately 1.5 times more than trees (EC/UN-ECE 2003). As dystric cambisol (2,292,385 ha) and eutric (869,909 are most widespread forest in Romania, we studied 5958 pedogenetic horizons 6784 horizons. A series correlations was made between soil elevation, but also with tree ...

Many topographic characteristics of the landscape (e.g. relief, slope, aspect, gradient, slope curvature, slope length and contour curvature) play important roles in the distribution of vegetation and biodiversity (e.g. Merriam, 1890, 1894; Whittaker & Niering, 1965, 1968; Vuilleumier, 1970; Brown, 1971, 1978; Hastings et al., 1972; Simpson, 1975; Hanawalt & Whittaker, 1976; Whittaker, 1977; Be...
