In order to estimate proper current land price, various factors such as environment, communication, regulation of land use and so on are established by local government. Road slope is one of the land price factors for land form, and land price is corrected by road slope aspect based on road slope for the north. For example, road slope aspect is corrected so that land price face to northern slop...
Various techniques have been proposed in the literature to detect and recognize full face images. However, only few attempts reported towards the problem of identifying and recognizing partial and occluded face images. In this direction, in this Paper, propose a method for recognition of a face under partial visibility. Initially, for every full face image in the training set, its intensity ima...
Slope stability is calculated using several methods. All these methods produce estimated results based on inaccurate assumptions, and their were particularly acceptable. Furthermore, rely supposing segmenting the surface of failure as well performing complex calculations. This paper introduces “Dimensional Analysis Technique” a new approach for dealing with earthen slopes. Four dimensionless gr...
In this paper we demonstrate the performance of a slope limiting procedure combined with a discontinuous Galerkin (DG) finite element solver for 2D compressible Euler equations. The slope limiter can be categorized into van Albada type and is differentiable. This slope limiter is modified from a similar limiter used in finite volume solvers to suit the needs of the DG solver. The gradient in an...
KDP single crystals were grown in aqueous solution by using "point seeds" with a defined crystallographic direction of 59° to the Z axis. When hillock slopes on the (100) face of KDP crystals were measured within the supersaturation (σ) range of 0 < σ ≤ 0.06, the slope of hillocks with hollow cores depended nonlinearly on supersaturation. Below σ = 0.02, the hillock slope depended on supersatur...
Geologic conditions and design requirements around upstream Nachtigal Falls, in Cameroon, for the hydroelectric construction project on Sanaga River dictated close control of blasting procedures with very precise geometry to obtain safe economical excavation lines. Various techniques pre-split were used initial stage all major excavations. Hole diameters pre-splitting 89 mm, hole spacing ranged...
seepage in earth fill dams is one of the important factors that may cause the erosion and slope instability if it is ignored. therefore, it is crucial to calculate the leakage discharge through the body of dam and foundation, to prevent economic and life hazards by considering technical and economical issues. in this research, the seepage analysis of the body and the stability of the upstream a...
Installation of baffles intended to improve fish passage through culverts can reduce discharge capacity and trap debris, increasing flood risk. A sloping upstream face may reduce this risk, but new designs must be tested for fish passage efficiency. The European eel (Anguilla anguilla) is a critically endangered species, yet the suitability of even common baffle types to aid upstream movement h...
