A novel modeling method for 3D curve welding seam is presented in this paper based on a welding robot for large workpiece. The 3D curve welding seam tracking is implemented by macro and micro motion which can control translational motion of torch in a large range and implement accurate seam tracking in small range. As such, the self-teaching seam model and real-time seam model are established t...

In this paper we consider the problem of implementing and optimizing the Seam Carving algorithm on graphics processing units. Seam Carving is a content-aware image resizing method proposed by Avidan and Shamir. In order to use their proposed method in real-time application, a pre-processing step is needed. While some other papers propose real-time resizing by changing the original Seam Carving ...

The context of this paper is Enterprise Architecture (EA). EA is a multi-disciplinary approach that allows different specialists to design new business and IT systems and focuses on the integration of these systems. Our group develops a specific EA method that is called SEAM. The current version of SEAM has a formal denotational semantics for its modeling language. In order to provide model sim...

Caenorhabditis elegans seam cells divide in the stem-like mode throughout larval development, with the ability to both self-renew and produce daughters that differentiate. Seam cells typically divide asymmetrically, giving rise to an anterior daughter that fuses with the hypodermis and a posterior daughter that proliferates further. Previously we have identified rnt-1 (a homologue of the mammal...

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...
