The longwall mining method is one of the most applied methods in extracting low-inclined to high-inclined coal seams. Selection of the most suitable extraction equipment is very important in the economical, safety, and productivity aspects of mining operations. There are a lot of parameters affecting the selection of an extraction equipment in mechanized longwall mining in steeply inclined coal...
ÐCurrent conceptual workflow models use either informally defined conceptual models or several formally defined conceptual models that capture different aspects of the workflow, e.g., the data, process, and organizational aspects of the workflow. To the best of our knowledge, there are no algorithms that can amalgamate these models to yield a single view of reality. A fragmented conceptual view...
In this paper, we propose a new method to adapt the resolution of images to the limited display resolution of mobile devices. We use the seam carving technique to identify and remove less relevant content in images. Seam carving achieves a high adaptation quality for landscape images and distortions caused by the removal of seams are very low compared to other techniques like scaling or croppin...
In automatically seam tracking system with structured light vision sensor in girth-welding of pipeline, there is a lot of noise in seam images. To extract seam information reliably, it is important to process the original images to eliminate influence of noise. A novel compounding process method is presented. Firstly, one dimension Laplacian of Gaussian filter was applied to transform noises wh...
Stem cells undergo symmetric and asymmetric division to maintain the dynamic equilibrium of the stem cell pool and also to generate a variety of differentiated cells. The homeostatic mechanism controlling the choice between self-renewal and differentiation of stem cells is poorly understood. We show here that ceh-16, encoding the C. elegans ortholog of the transcription factor Engrailed, contro...

A conical intersection seam is behind the restriction of intramolecular rotation mechanism for aggregation induced emission in diphenyl dibenzofulvene (DPDBF). In solution, the seam is accessed through rotation around the exocyclic fulvene bond, leading to radiationless decay to the ground state. In the solid, the seam cannot be accessed because the torsion is blocked, and DPDBF becomes emissive.
Room-and-pillar mining with pillar recovery has historically been associated with more than 25% of all ground fall fatalities in underground coal mines in the United States. The risk of ground falls during pillar recovery increases in multiple-seam mining conditions. The hazards associated with pillar recovery in multiple-seam mining include roof cutters, roof falls, rib rolls, coal outbursts, ...
When a video is displayed on a smaller screen than originally intended, some of the information in the video is necessarily lost. In this paper, we introduce Video Retargeting that adapts video to better suit the target display, minimizing the important information lost. We can remove uninteresting part from video like image with some important modifications to retarget it using seam carving. I...
