The rip fence is parallel to the saw blade and can be adjusted to different distances from the blade to set the size of the final cut. The fence remains static, while the workpiece is guided along the fence. [5] For crosscuts a sliding cross-cut fence or a mitre gauge – which incorporates a fence – is used.
In linear algebra, the restricted isometry property (RIP) characterizes matrices which are nearly orthonormal, at least when operating on sparse vectors. The concept was introduced by Emmanuel Candès and Terence Tao [ 1 ] and is used to prove many theorems in the field of compressed sensing . [ 2 ]
Silt fence installed on a construction site. Silt fences are often installed as perimeter controls. They are typically used in combination with sediment basins and sediment traps, as well as with erosion controls, which are designed to retain sediment in place where soil is being disturbed by construction processes (i.e., land grading and other earthworks).
Cropped delta: wing tips are cut off. This helps avoid tip drag at high angles of attack. The Fairey Delta 1 also had a tail. At the extreme, merges into the "tapered swept" configuration. Compound delta or double delta: inner section has a (usually) steeper leading edge sweep as on the Saab Draken. This improves the lift at high angles of ...
The first true performance-oriented Delta was the Delta HF, which was introduced in July 1983 and went on sale in September [18] after a first appearance at the Frankfurt Motor Show. [19] The HF acronym—last used on the Stratos —stands for "high fidelity", and had been applied to sports and racing variants of Lancia cars since 1966. [ 20 ]

The Gloster Javelin is a twin-engined all-weather interceptor aircraft that served with Britain's Royal Air Force from the mid-1950s until the late 1960s. It was a T-tailed delta-wing aircraft designed for night and all-weather operations and was the last aircraft design to bear the Gloster name.
The Deltic-powered Hunt-class mine countermeasures vessel HMS Ledbury. Development began in 1947 and the first Deltic model was the D18-11B, produced in 1950. It was designed to produce 2,500 hp (1,900 kW) at 2000 rpm for a 15-minute rating; the continuous rating being 1,875 hp (1,398 kW) at 1700 rpm, based on a 10,000-hour overhaul or replacement life. [3]
