To determine the degree of mining affection on surface or in strata, the GIS technique is used, with Mapinfo as the platform. Through programming of seam inclination-based subsidence mathematical models and mining disturbance analysis visualization, Mapbasic/Vc++/Vfortran programming design is realized under Windows. The program system provides not only an effective approach for model analysis,...

In order to study the coal pillar stability of gob-side entry in gently inclined seam, a comprehensive method including theoretical analysis, numerical modeling, and field monitoring was applied its fracturing instability mechanism. The results show that uneven horizontal stress internal cause asymmetric deformation failure seam. rotation movement main roof distribution were closely related inc...

Increasing the production rate and minimizing the related costs, while optimizing the safety measures, are nowadays’ most important tasks in the mining industry. To these ends, mechanization of mines could be applied, which can result in significant cost reductions and higher levels of profitability for underground mines. The potential of a coal mine mechanization depends on some important fact...

Periodic spontaneous erection and penile movements known as masturbation (SEAM) occur normally at approximately 90 min intervals in awake equids. SEAM in horses has traditionally been misunderstood by many horsemen as aberrant behavior that should be eliminated. Accordingly, it is not uncommon for trainers of performance stallions or managers of breeding stallions to punish SEAM in an attempt t...

Content-aware resizing methods have recently been developed, among which, seam-carving has achieved the most widespread use. Seam-carving’s versatility enables deliberate object removal and benign image resizing, in which perceptually important content is preserved. Both types of modifications compromise the utility and validity of the modified images as evidence in legal and journalistic appli...

Based on rapid upsurge in the demand and usage of electronic media devices such as tablets, smart phones, laptops, personal computers, etc. and its different display specifications including the size and shapes, image retargeting became one of the key components of communication technology and internet. The existing techniques in image resizing cannot save the most valuable information of image...

A scheme is described for the automatic domain decomposition and creation of overset grids around surface discontinuities. Curves along surface discontinuities are called seam curves. The seam curves are rst automatically extracted from a multiple panel network description of the surface. Points where three or more seam curves meet are automatically identied and are called seam corners. Surface...

we studied Attenuation in Fiber Optics, used two type of Fibers (Plastic and glass) with length (0.5,5,20m) (1,20,100m) respectively wavelength laser (660nm, 850nm), found attenuation increase 850nm 660nm are the best for plastic fiber optics, addition which occur from axial gap, axes rotation, inclination angle, transversal displacement investigated. Influence three values linear dispersion on...

Seam carving is a powerful retargeting algorithm for mapping images to arbitrary sizes with arbitrary aspect ratios. Meanwhile, the seamlet transform has been introduced as an efficient image representation for seam-carving-based retargeting over heterogeneous multimedia devices with a broad range of display sizes. The original seamlet transform was developed using Haar filters, and hence it en...

A single line of epidermal seam cells lies along each side of the nematode C. elegans. During normal development, one of these cells, V5, produces a neuroblast that will give rise to a sensory structure, the postdeirid. If seam cells located either anterior or posterior to V5 are ablated however, this neuroblast formation is blocked. Because of this requirement for the presence of adjacent seam...
