Abstract The aims of this paper are to comprehensively explore both the dynamic mechanical properties and crack evolution characteristics coal rock during impact failure. First, experimental specimens prepared from seam, direct roof strata floor in same area highlight correlations between test pieces. Second, a strain gauge high-speed (HS) camera adopted reflect stress wave signal evolution. Th...

In mammals, circadian rhythms are controlled by a master clock localized in the suprachiasmatic nucleus (SCN) and entrained to 24 h by external cues. These signals are conveyed by three main afferences: the retinohypothalamic tract (RHT), the geniculohypothalamic tract (GHT) and the serotonergic tract. Photic factors during the night, leading to glutamate release from the RHT and c-Fos and cloc...

This paper proposes a new algorithm for 2-D object detection called Randomized Generalized Hough Transform (RGHT). It combines the Generalized Hough Transform (GHT) with the Randomized Hough Transform (RHT). Our algorithm can detect arbitrary objects of various scales and orientations in graylevel images. We also demonstrate RGHT’s advantage of high speed, low storage requirement, high accuracy...

For a series of metal-organic frameworks with rht topology, we study computationally the effect of the linker length on the surface area, pore size, and pore volume, relating them with the hydrogen adsorption properties. The results provide new insights about the excess capacities and the pressures where the uptake maxima in the excess isotherms occur. We found that, of the materials studied, ...

Graph embedding problems have gained importance in the field of interconnection networks for parallel computer architectures. Interconnection networks provide an effective mechanism for exchanging data between processors in a parallel computing system. In this paper, we embed the rooted hypertree RHT (r) into r-dimensional hypercube Q with dilation 2, r ≥ 2. Also, we compute the exact wirelengt...
