Anchor modeling is an agile database modeling technique suited for information that changes over time both in structure and content. It provides a graphical notation used for conceptual modeling similar to that of entity-relationship modeling , with extensions for working with temporal data .
Thus, the vibration energy is retained in the resonator body, reducing the anchor losses into the substrate. [17] Besides the phonon crystal tether, some other kinds of metamaterial could be applied to the anchor and surrounding regions to prohibit the wave transmission. [18] A key drawback of this method is the challenge to the fabrication ...
The tension failure loads predicted by the CCD method fits experimental results over a wide range of embedment depth (e.g. 100 – 600 mm). [2] Anchor load bearing capacity provided by ACI 349 does not consider size effect, thus an underestimated value for the load-carrying capacity is obtained for large embedment depths.
A set of kite lines. In kiting, a line is the string or thin cord made of cotton, nylon, silk, or wire, which connects the kite to the person operating it or an anchor. Kites have a set of wings, a set of anchors, and a set of lines coupling the wings with the anchors. Kite lines perform various roles: bridle, control, tug, or special duty.
The resultant force vector from the lift and drag force components is opposed by the tension of one or more of the lines or tethers to which the kite is attached. [6] The anchor point of the kite line may be static or moving (e.g., the towing of a kite by a running person, boat, free-falling anchors as in paragliders and fugitive parakites [7 ...
The full-size anchor weighed 330 kg (730 lb) and, during performance tests using a large tug, it held up to 30 tons. The Ministry of Supply ordered 2,332 Kite anchors, as they became known, to be manufactured at a total cost of £89,786, with more than 2,000 of the anchors being used on the two Mulberry harbours.

Two (or more) kites, kite-lined to one anchor, one mooring or one kite operator, are included here. Two kites (or more) communicating with each other for a purpose are coupled. Dragon kites Two categories: those mimicking the figure of a dragon in a decoration or figure kite, and those of a series of kites in a train or stack. [130] [131] [132 ...
A deep-penetrating anchor (DPA) is conceptually similar to a torpedo anchor: it features a dart-shaped, thick-walled, steel cylinder with flukes attached to the upper section of the anchor. A full-scale DPA is approximately 15 metres (49 ft) in length, 1.2 metres (4 ft) in diameter, and weighs on the order of 50–100 tonnes (49–98 long tons ...
