Passive remote sensing (RS) of solar-induced chlorophyll fluorescence (SIF) of vegetation is feasible at ground level, airborne level and space borne level with certain prototypes. Fraunhofer Line Discrimination (FLD) and its improved methods have been widely used to extract SIF. Unlike processing at ground level, these methods do not work so well since it is not easy to obtain the solar incide...

A FGM layer sandwiched between two isotropic layers weakened by several interface cracks under antiplane loading is studied. This paper examines the modelling of cracks by distribution of strain nuclei along crack lines. In this investigation, the Volterra-type screw dislocation employed between FGM and an elastic layer. To solve the dislocation problem, the complex Fourier transform is applied...

in the present investigation, the cyclic load deformation behaviour of soil-fly ash layered system isstudied using different intensities of failure load (i = 25%, 50% and 75%) with varying number of cycles (n =10, 50 and 100). an attempt has been made to establish the use of fly ash as a fill material for embankments ofhighways and railways and to examine the effect of cyclic loading on the lay...

Some cyclically loaded components such as mooring chains can develop fatigue cracks in locations where the shape of part is equivalent to that a curved or bent round bar. Here we consider semi-elliptical crack growing from surface This geometry for example represent chain link segment with located at its inner- outer radius. The be either almond shaped, sickle shaped straight-fronted. Stress in...

OBJECTIVE The aim of this study was to identify the risk factors associated with the prognosis of a subchondral insufficiency fracture of the femoral head (SIF). METHODS Between June 2002 and July 2009, 25 patients diagnosed with SIF were included in this study. Sequential radiographs were evaluated for the progression of collapse. Clinical profiles, including age, body mass index, follow-up ...

This work presents concepts and algorithms for the simulation of dynamic fractures with a Lattice Boltzmann method (LBM) linear elastic solids. LBM has been presented previously solves wave equation, which is interpreted as governing equation antiplane shear deformation. Besides steady growth crack at prescribed velocity, fracture criterion based on stress intensity factors (SIF) implemented. f...
