The analytical solutions of wave induced horizontal and vertical forces on perforated caissons resting on porous elastic seabed have been established. The solution in the seabed is divided into a symmetric part and an anti-symmetric part. A numerical experiment has been carried out to examine the effects on horizontal forces, vertical forces and phase lags between them due to the relative wave ...

This paper presents an error analysis for voxel colarang 12, 31, which is one of the well known methods to reconstruct 3D shape from 2D calibrated multiple-view images. In order to analyze the errors arising in the reconstruction process of voxel coloring algorithms, we first model several noise sources in the analytic or statistical way, and then examine the effects of each noise component on ...

In controlling manipulators interacting with the external environment, an important issue is the choice and construction of the Cartesian level control system. To eeec-tively control the constrained manipulators, a knowledge of the resulting compliance of the system is required. In this paper a systematic analysis of the Cartesian stii-ness and compliance matrices, which at full extent has not ...

This paper proposes a system for automatic video analysis to detect events in video sequences with crowds of people. In detail, the proposed system consists of three subsystems: 1) the first identifies the motion areas, resorting to chaos theory using joint histogram between consecutive frames, 2) the second one creates a flow motion map that describes the behavior of motion pixels by using Lag...

Nifedipine (NIF), a 1,4-dihydropyridine calcium channel antagonist, undergoes photo-degradation to dehydro-nifedipine (DNIF) upon exposure to ultraviolet (UV) light and to the nitroso analogue of dehydro-nifedipine (NDNIF) when exposed to sunlight or some kinds of artificial lights. NIF photo-degradation products do not contribute to clinical activity, thus prevention of photo-degradation of NI...

In this research in numerical analysis software packages SIGMA / W based on the finite element method was to have been used. For this purpose, during the construction of the dam Kaboodval using behavioral models elastic - plastic and elastic non-homogeneous, non-linear elastic, linear elastic been analyzed and pore pressure, stresses in the body and its meeting with the Data Tools the compariso...

The influence of elastic properties on finite-element analysis was investigated using a finite-element model of a Macaca fascicularis skull. Four finite-element analyses were performed in which the model was assigned different sets of elastic properties. In analysis 1, elastic properties were modeled isotropically using published data obtained from human limb bones. Analyses 2-4 used data obtai...

abstract in this study, we applied recently developed panel unit root and cointegration techniques to examine the long-run real income per capita and price elasticities for demand of electricity in selected middle east and north african (mena) countries using an annual data series from 1990 to 2011.our main finding from the panel analysis is that the demand for electricity is highly price elast...
