Full-scale tests were performed to study the penetration resistance of steel plates (skirts), which are common foundation elements jacket offshore wind structures. Penetration is well-studied in clays and sands, but there limited information on gravels, typically used as scour protection critical like substations. Direct extrapolation sands not possible because grain-size effect. Two plate thic...

Abstract The operation state of insulators is closely related to the safety and reliability power network. Affected by environment, insulator strings will gradually age become low-value or zero-value in insulators. Therefore, it great engineering significance correctly timely detect whether there are faults It has a good application prospect evaluate insulation condition detecting surface elect...

We present promising results for real-time vehicle visual detection, obtained with adaBoost using new original “keypoints presence features”. These weak-classifiers produce a boolean response based on presence or absence in the tested image of a “keypoint” (~ a SURF interest point) with a descriptor sufficiently similar (i.e. within a given distance) to a reference descriptor characterizing the...

Caenorhabditis elegans is an androdioecious nematode composed of selfing hermaphrodites and rare males. A model of male maintenance demonstrates that selfing rates in hermaphrodites cannot be too high or else the frequency of males will be driven down to the rate of spontaneous nondisjunction of the X chromosome. After their outcrossing ability is assessed, males are found to skirt the frequenc...

Utilizing the rigorous field distribution of the ridge waveguide eigemnortes, this paper presents an accurate computer-aided design of compact, low-cost, low-insertion-loss evanescent-mode waveguide band-pass filters with bilateral metallic E-plane fins. The design theory takes into account the influences of both the finite fin thickness and the higher order mode interaction at all discontinuit...

Engineering a cell-based keratoprosthesis often requires a struggle between two essential parameters: natural 3-D biological adhesion and mechanical strength. A novel hybrid scaffold of natural and synthetic materials was engineered to achieve both cell adhesion and implantable strength. This scaffold was characterized in terms of cell adhesion, cell migration, swelling, and strength. While the...
