The expression and activity of receptor tyrosine kinases (RTK) at the cell surface can be modulated by several different pathways including the proteolytic release of the extracellular domain as a soluble receptor. We investigated the regulation of tie receptor expression, an orphan RTK restricted to cells of hematopoietic and endothelial lineages, on primary human endothelial cells and a stabl...

To provide rapid analysis for the ongoing status of emergency, the captured aerial images must be georeferenced to the same coordinate system as the existing spatial data in real-time. This study presents a development of an automated real-time image georeferencing which involves a novel image matching and simultaneous AT. We implemented a reliable fast-and-automated image matching based on the...

We study a combinatorial game called Bichromatic Triangle Game, defined as follows. Two players R and B construct a triangulation on a given planar point set V . Starting from no edges, players R and B take turns drawing one edge that connects two points in V . Player R uses color red and player B uses color blue. The first player who completes one empty monochromatic triangle is the winner. We...

Convex hull of some given points is the intersection of all convex sets containing them. It is used as primary structure in many other problems in computational geometry and other areas like image processing, model identification, geographical data systems, and triangular computation of a set of points and so on. Computing the convex hull of a set of point is one of the most fundamental and imp...

We study a combinatorial game called Bichromatic Triangle Game, defined as follows. Two players R and B construct a triangulation on a given planar point set V . Starting from no edges, they take turns drawing one straight edge that connects two points in V and does not cross any of the previously drawn edges. PlayerR uses color red and player B uses color blue. The first player who completes o...

This paper presents a matching strategy for sparsely distributed tie points, which can be used to carry out SAR-optical stereogrammetry. Since matching homologue points in heterogeneous multi-sensor image of complex terrain remains a challenging task, the proposed procedure combines the tie point matching step with the estimation of the corresponding 3D object coordinates. The results of this s...

We present a fully automatic method for the alignment SAR images, which is capable of precise and robust alignment. A multiresolution SAR image matching metric is first used to automatically determine tie-points, which are then used to perform coarse-to-fine resolution image alignment. A formalism is developed for the automatic determination of tie-point regions that contain sufficiently distin...

when power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. sssc is a facts device con...

An automatic process for relative registering and merging the panchromatic and multispectral images of SPOT5 is presented. The automated hierarchical local registration process makes use of feature information to select tie points from both images. The tie points are then used to refine the sensor model of the multispectral image by method of least squares solution. Both panchromatic and multis...
