A new method for varying adaptive bandwidth selection

With the motivation to overcome the shortcomings of the Rosenblatt Inverse-First-Order Reliability environmental contour method, in this study, the use of bivariate kernel density estimation with smoothed cross-validation bandwidth selection method is proposed for generating more accurate environmental contour lines. The environmental contour lines at a chosen offshore site obtained by using the proposed new method were compared with those obtained by using the Rosenblatt Inverse-First-Order Reliability environmental contour method, and the accuracy and effectiveness of the proposed new method have been fully and clearly substantiated. Next, the 50-year extreme structural dynamic responses of a monopile-supported 5MW offshore wind turbine installed at this chosen offshore site based on the proposed new method and the Rosenblatt Inverse-First-Order Reliability environmental contour approach were calculated. Analyzing the calculating results, it can be found that the 50-year extreme fore-aft shear force value based on the 50-year extreme sea state obtained using the proposed new method is 78.9% larger than the corresponding value obtained based on the Rosenblatt Inverse-First-Order Reliability contour method. The calculation results in this paper were further systematically analyzed and compared, and the necessity and importance of using more realistic environmental contour lines (such as those generated using the proposed new method) have been finally highlighted.

Specific Orientation

Investigations which require electron microscope examination of a few specific areas of non-homogeneous tissues make random sampling of small blocks an inefficient and unrewarding procedure. Therefore, several investigators have devised methods which allow obtaining sample blocks for electron microscopy from region of tissue previously identified by light microscopy of present here techniques which make possible: 1) sampling tissue for electron microscopy from selected areas previously identified by light microscopy of relatively large pieces of tissue; 2) dehydration and embedding large numbers of individually identified blocks while keeping each one separate; 3) a new method of maintaining specific orientation of blocks during embedding; 4) special light microscopic staining or fluorescent procedures and electron microscopy on immediately adjacent small areas of tissue.
