As an indicator of the stability spectral clustering undirected weighted graph into k clusters, th gap Laplacian is often considered. The characterized in this paper as unstructured distance to ambiguity, namely minimal arbitrary symmetric matrices with vanishing gap. a conceptually more appropriate measure stability, structured ambiguity -clustering introduced Laplacians graphs same vertices a...
this research concentrates on the lithostratigraphy, biostratigraphy, microfacies and sedimentary environment of the asmari and gachsaran formations at southwest firuzabad. the thickness of the studied section in all 608.95 meters that 220.8 meters belong to the asmari formation and 387.95 meters belong to the gachsaran formation (champe and mol members). in the study area, the asmari formation...
This paper investigates symmetrical buckling of orthotropic circular and annular plates of continuous variable thickness. Uniform compression loading is applied at the plate outer boundary. Thickness varies linearly along radial direction. Inner edge is free, while outer edge has different boundary conditions: clamped, simply and elastically restraint against rotation. The optimized Ritz method...
in islam, the world and hereafter life, plurality and unity, and inner and outer part each has its own place. islamic spirituality as an inner knowledge finds connection with islamic social idea. the purpose of which is a kind of social education and human life edification in all aspects, because, in view of the gnostics, the outer and inner worlds have longitudinal relationship.the mystics in ...
background: gasoline station workers are exposed to volatile organic compounds such as benzene, toluene, ethylbenzene and xylene (btex). objectives: to determine the level of exposure to btex compounds among gasoline station workers and measure the roadside concentrations of these compounds in the inner and outer areas of bangkok, thailand. methods: 49 workers at 6 gasoline stations in the inne...
The single-phase flow and thermal performance of a double pipe heat exchanger are examined by experimental methods. The working fluid is water at atmospheric pressure. Temperature measurements at the inlet and outlet of the two streams and also at an intermediate point half way between the inlet and outlet is made, using copper-constantan thermocouple wires. Mass flow rates for each stream are ...
In this paper, we study robust iterative solvers for finite element systems resulting in approximation of steady-state Richards’ equation in porous media with highly heterogeneous conductivity fields. It is known that in such cases the contrast, ratio between the highest and lowest values of the conductivity, can adversely affect the performance of the preconditioners and, consequently, a desig...
laminar mixed convection of aluminium oxide (al2o3)–water nanofluid flow in an inclined annulus using a single-phase approach was numerically studied. constant heat flux boundary conditions were applied on the inner and outer walls. all the thermophysical properties of nanofluid, such as, viscosity, heat capacity, thermal conductivity, and thermal expansion coefficient, except density in the bo...
