A new method of fractal measurement, the projective covering method (PCM), is proposed in this Letter. Based on the measurements by means of a laser profilometer, the fractal dimension D E [2,3) of a fracture surface is directly estimated. The projective covering probability function is introduced to systematically analyze the multifractal behavior of the fracture surfaces. @ 1998 Elsevier Scie...

the use of satellite data in an estimation of air temperature (ta) near the earth’s surface has turned into an effective way for a large area of high spatial and temporal resolution. throughout the present study, artificial neural network (ann) as well as m5 model tree were employed to estimate ta in khuzestan province (south west of iran), using satellite remotely sensed land surface temperatu...

soil surfaces in arid and semi-arid lands often lack photoautotrophic life but are covered by communities of soil surface covering organisms able to tolerate dehydration, and thus adapted to aridity. one important objective of multi-spectral remote sensing instruments is the detection of the optical characteristics of the earth’s surface using high spectral resolution bands. in this study aster...
