Pore structure is a critical factor affecting the strength characteristics of mine backfill materials. In this paper, based on mechanical tests lime modified phosphogypsum cemented (LMPGCB), microstructure LMPGCB sample was characterized by nuclear magnetic resonance (NMR) and scanning electron microscopy (SEM) imaging. Based fractal theory (FT), values expressing NMR T2 spectrum SEM images wer...

We have built a vertical seismometer that works based on the moiré technique. One grating is attached to the suspended mass and one to the frame of the instrument. The two gratings are in relative motion, and the resulting moiré pattern magnifies this motion. The intensity of a light beam passing through the moving moiré fringes changes with time, and a light detecting syst...

background and objectives: retinoblastoma is the most common intraocular pediatric malignancy. angiogenic factor expression such as vegf (vascular endothelial growth factor) in retinoblastoma can be confirmatory angiogenic potential of this tumor. this study was performed to determine the role of angiogenesis in local invasion of retinoblastoma and its correlation with patients’ survival. mater...

Objectives: The aim of this study was to evaluate the importance of enhanced visual acuity in evaluation of polishing composite resins. Material and Methods: Forty-five composite samples were used. Finishing and polishing discs were used to produce samples with different surface roughness values (Ra). The observers examined the resin surfaces according to the following scale: 1: Smooth (0.01-0....

This paper adds depth to motion magnification. With the rise of cheap RGB+D cameras depth information is readily available. We make use of depth to make motion magnification robust to occlusion and large motions. Current approaches require a manual drawn pixel mask over all frames in the area of interest which is cumbersome and errorprone. By including depth, we avoid manual annotation and magn...
