in synthetic aperture radar (sar) imagery, ship-sea contrast can be significantly improved when the polarimetric information is used, compared with information from a single channel sar. the constant false alarm rate (cfar) detection algorithm based on the alpha-stable (as) distribution model is a descent method for ship detection in sea. the most important step in this method is the parameter ...
Flow boiling in a straight\ rectangular channel was investigated to explore the conditions leading to critical heat ~ux "CHF#[ The ~ow channel had a 4[9×1[4 mm cross!section and 090[5 mm heated length^ heat was applied to the shorter dimension along only one wall[ Tests were performed with FC!61 liquid over a velocity range of 9[14 to 09 m s and at outlet subcoolings of 2\ 05 and 18>C[ Video im...
Well crystallized pure calcium zirconate (CaZrO3 ) nanopowder was successfully synthesized using the molten-salt method. CaCl2 , Na 2CO3, micro-ZrO 2and nano-ZrO 2 were used as starting materials. On heating, Na2CO3 reacted with CaCl 2to form NaCl and CaCO 3. Nano CaZrO 3 was formed by reacting equimolar amounts of in situformed CaCO 3 (or CaO) and ZrO 2 in molten Na 2CO3-NaCl e...
A vertical soap film is maintained by injection of a soap solution from the top. The film is then locally heated. Thermal plumes may be observed to rise in the film, depending on the magnitude of the heating and injected flows. The nearly two-dimensional nature of the system allows to visualize the motion of the plumes using an infrared camera. A model is proposed to describe the growth, emerge...
We develop and computationally analyze a mathematical model for natural convection to non-Newtonian fluid in long thin channel. The channel is bounded by antisymmetric heated cooled walls encloses pseudoplastic fluid. flow heat transfer characteristics are investigated subject the prevailing buoyancy forces resulting from combined gravitational effects. An efficient accurate semi-implicit finit...
in this paper first we try to analysis the behavior ofthe soas in the optical networks and then have proposed anumerical simple model to simulate the behavior of thesemiconductor optical amplifiers. after that by employing thismodel as inline amplifier for a dwdm optical system, we havesimulated the transmission of 10 channels with bit rate 10 gb/sup to distance 3970 km with rz-dpsk modulation ...
background: non-dystrophic myotonias are a heterogeneous set of skeletal, muscular channelopathies, which have been associated with point mutations within sodium channel α-subunit (scn4a) gene. because exons 22 and 24 of scn4a gene are recognized as hot spots for this disease, the purpose of the study is to identify mutation in exons 22 and 24 of scn4a gene in iranian non-dystrophic myotonias p...
