Dynamic convex hull maintenance: The input points may be sequentially inserted or deleted, and the convex hull must be updated after each insert/delete operation. Insertion of a point may increase the number of vertices of a convex hull at most by 1, while deletion may convert an n-vertex convex hull into an n-1-vertex one.
John Crosthwaite (9 October 1925 – 5 September 2010) was an English race car designer and engineer, active in both the United Kingdom and the United States..

The naval architecture firm A. K. Suda, Ltd. designed a 450-foot (137.25m) truss-legged liftboat for Teras Offshore. When delivered in 2014, it was the world's largest liftboat. The molded steel hull dimensions are 60m x 54m x 6m, and it is capable of working in water depths up to 367 feet.
A vehicle with a 5,000 lb (2,300 kg) capacity with the boom retracted may be able to safely lift as little as 400 lb (180 kg) with it fully extended at a low boom angle. The same machine with a 5,000 lb (2,300 kg) lift capacity with the boom retracted may be able to support as much as 10,000 lb (4,500 kg) with the boom raised to 70°.
This increases lift and reduces drag, so that at speed only a few inches of the boat touch the water, leading to the high speed possible with these hulls. [ 11 ] F1 boats are powered by a Mercury Marine [ citation needed ] V6 two stroke that burns 100LL Avgas at a rate of 120 liters (32 gallons) per hour, generating over 400 horsepower at ...
A Contender dinghy planing on a broad reach. Note the typical way the bow lifts up while the stern skims over the water. Planing (/ ˈ p l eɪ n ɪ ŋ / PLAY-ning) is the mode of operation for a waterborne craft in which its weight is predominantly supported by hydrodynamic lift, rather than hydrostatic lift ().
Buddy Valastro is looking pretty svelte these days, and he's ready to share the small lifestyle changes that helped him shed nearly 40 pounds over the past nine months.
A jackup rig or a self-elevating unit is a type of mobile platform that consists of a buoyant hull fitted with a number of movable legs, capable of raising its hull over the surface of the sea. The buoyant hull enables transportation of the unit and all attached machinery to a desired location.
