The objective of this research is to improve the surface flux and boundary layer turbulence parameterization in COAMPS for lowand high-wind events over the ocean in the context of air-sea interaction. Special emphasis will be placed on flux parameterizations in low-wind regimes in collaboration with CBLAST DRI (Coupled Boundary Layer Layers/Air-Sea Transfer Defense Research Initiative) community.

The paper presents a methods to retrieve the speed of the sea surface from Along Track Interferometry (ATI) data beside the typical use for target speed retrieval, which is also mentioned. The describe technique provides for a data prefiltering in order to obtain the necessary accuracy because of the law speed range of the currents. Furthermore, an example of target velocity estimation is provi...

International Rectifier has used a proprietary technique to position all the terminals of a HEXFET device on the same face of the die. This has enabled the development of wafer scale packaged MOSFETs. We're calling the technology platform the FlipFET MOSFET, and we are using it to offer surface mount products with the lowest RDS(on) per footprint area in the industry. This paper introduces the ...

Given a curvilinear geometric object in R 3 , made up of properly-joined para-metric patches deened in terms of control points, it is of interest to know under what conditions the object will retain its original topological form when the control points are perturbed. For example, the patches might be triangular B ezier surface patches, and the geometric object may represent the boundary of a so...

We present a novel approach named T-Base for smoothing planar and surface quadrilateral meshes. Our motivation is that the best shape of quadrilateral element – square – can be virtually divided into a pair of equilateral right triangles by any of its diagonals. When move a node to smooth a quadrilateral, it is optimal to make a pair of triangles divided by a diagonal be equilateral right trian...

In my research a 3D model was created to investigate the restoring force arising and the self-alignment occurring during reflow soldering; and simulations were performed to examine the assumptions given by the model. Besides, experiments were carried out to verify both the assumptions and the simulation predictions. Passive components with the size of 0603 (1.5 x 0.75 mm) were placed with inten...

A subgroup of a group is known as a surface subgroup if it is isomorphic to the fundamental group of a closed connected orientable surface with positive genus. The surface subgroup conjecture in low-dimensional topology proposes that if the fundamental group of a closed orientable irreducible 3-manifold is infinite, then it contains a surface subgroup. With the recent solution to the geometrisa...

The problem of visible surface estimation for image-based rendering is tackled using a new approach, which combines visual hull and surface estimation techniques. It is shown that the new method combines the best features of both approaches, being more robust than direct surface element estimation and more flexible than the visual hull. The new method uses an estimate of the visual hull as a pr...

An experimental investigation of a surface analysis method has been carried out. The method uses a scanned laser line to detect scratches on glass surfaces. The defects are detected as differences in the scattered light, which are recorded with a digital camera. A problem with this method is to distinguish between light from the back and from the front of the sample, since transparent samples a...

In this paper, we propose an algorithm for estimating dense shape and motion of dynamic piecewise planar scenes from region correspondences using factorization. Region correspondences are used since they are easier to establish and more reliable than either line or point correspondences. The image measurements required are the centroid and area for each region. Singular value decomposition is e...
