Abstract. Purpose. The work’s aim is to check the stability loss hypothesis with snap-through effect of ribbed-annular dome's upper tier on a full-scale model by experimental tests, and confirming nonlinear tier's work under external load. Methodology. ribbed-ring dome circumscri
High Resolution Imaging of the Ocean Surface Backscatter by Inversion of Altimeter Waveforms
All the satellite altimeters use pulse-limited-geometry and full-deramp technique to measure the power backscatter by the ocean surface as a function of time, i.e. the altimeter pulse echo waveform, see for example [1] for explanation on pulse limited altimeters). Assuming that t
A REVIEW OF GAS-LIQUID CYLINDRICAL CYCLONE (GLCC) TECHNOLOGY by G. E. Kouba
Economic pressures continue to force the petroleum industry to seek less expensive alternatives to conventional gravity based separation. The gas-liquid cylindrical cyclone (GLCC) is a simple, compact, low-cost separator that can provide an economically attractive alternative to
Post-analysis for the line source phase IIIA experiments of the USDOE/JAERI collaborative program on fusion neutronics
Experimental simulation to a line source has been realized at FNS, JAERI, within the USDOE/JAERI collaborative Program on Fusion Neutronics. This simulation achieved by cyclic movement of an annular Li20 test assembly relative to a stationary point source was a step forward in be
Shear-SANS study of single-walled carbon nanotube suspensions
We report a combined shear small-angle neutron scattering (shear-SANS) and rheo-optical study of dilute aqueous suspensions of SWNT bundles dispersed using ionic surfactants. Both shear-SANS and flow birefringence reveal weak shear-induced alignment of SWNT bundles along the dire
Application of the Particle Image Velocimetry to the Couette-Taylor Flow
For longtime, the investigation of flow regimes has been achieved using fluorescent particles or anisotropic reflective particles. Fluorescent particles are suitable for open flows (Van Dyke, 1982) such as flows in channels (Peerhossaini et al., 1988) or flows behind a cylinder (
Iris Recognition based on Local sharp Variation Points
A wide variety of systems require reliable personal recognition schemes. With the development of biometric recognition technology it is found that iris is one of the most reliable biometric recognition schemes because of its randomly distributed features and unique characteristic
Sound attenuation in dissipative expansion chambers
Recent improvements in fiber properties combined with their broadband acoustic dissipation characteristics make such materials potentially desirable for implementation in silencers. The acoustic modelling of simple silencer geometries, such as circular or rectangular cross-sectio
Multidomain Local Fourier Method for PDEs in Complex Geometries
but with higher frequencies and amplitudes of the oscillating components), only a low accuracy can be achieved after an aaordable number of PCG iterations. The reason is that a strip-wise domain decomposition cannot handle large changes in non-constant coeecients in the lengthwis
