Kauaʻi, anglicized as Kauai, is geologically the second-oldest of the main Hawaiian Islands. With an area of 562.3 square miles, it is the fourth-largest of the islands and the 21st-largest island in the United States. Nicknamed the Garden Isle, Kauaʻi lies 73 miles across the Kauaʻi Channel, northwest of Oʻahu. It is the site of Waimea Canyon State Park and the Na Pali Coast State Park.
A cantilever is a rigid structural element that extends horizontally and is unsupported at one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab.
The Knudsen number (Kn) is a dimensionless number defined as the ratio of the molecular mean free path length to a representative physical length scale. This length scale could be, for example, the radius of a body in a fluid. The number is named after Danish physicist Martin Knudsen (1871–1949).
Gunnar Knudsen, born Aanon Gunerius Knudsen, was a Norwegian politician from the Liberal Party who served as the 11th prime minister of Norway twice from 1908 to 1910 and from 1913 to 1920. He also inherited a shipping company, and founded the shipping company Borgestad ASA.
Norway was represented at the 1972 Summer Olympics in Munich by the Norwegian Olympic Committee and Confederation of Sports. 112 competitors, 101 men and 11 women, took part in 70 events in 15 sports.
Clear Space Force Station is a United States Space Force radar station for detecting incoming ICBMs and submarine-launched ballistic missiles to NORAD's command center and to provide Space Surveillance data to the United States Space Force. Clear's AN/FPS-123 Upgraded Early Warning Radar is part of the Solid State Phased Array Radar System (SSPARS) which also includes those at Beale AFB, Cape Cod Space Force Station, RAF Fylingdales and Thule Site J. The "historic property" was one of the Alaska World War II Army Airfields and later a Cold War BMEWS site providing NORAD data to Colorado's BMEWS Central Computer and Display Facility (CC&DF).
William Signius Knudsen was a leading Danish-American automotive industry executive and an American general during World War II. His experience and success as a key senior manager in the operations sides of Ford Motor Company and then General Motors led the Franklin Roosevelt administration to commission him directly as a lieutenant general in the United States Army to help lead the United States' war materiel production efforts for World War II.
The passenger locomotives derivatives of the General Motors EMD GP40 diesel-electric locomotive have been, and continue to be, used by multiple passenger railroads in North America. For passenger service, the locomotives required extra components for providing steam or head-end power (HEP) for heating, lighting and electricity in passenger cars. Most of these passenger locomotives were rebuilt from older freight locomotives, while some were built as brand new models.
In the United States Armed Forces, a lieutenant general is a three-star general officer in the United States Army, Marine Corps, Air Force, and Space Force.
Jens Martin Knudsen is a former Faroese goalkeeper and businessman. He was perhaps best known for wearing a hat in his matches as a result of an injury he suffered at age 14. He later become known as "the bobble hat goalkeeper".
Keith A. Knudsen was an American rock drummer, vocalist, and songwriter. Knudsen was best known as a drummer and vocalist for The Doobie Brothers. In addition, he founded the band Southern Pacific with fellow Doobie Brother John McFee. He was posthumously inducted into the Rock and Roll Hall of Fame as a member of The Doobie Brothers in 2020.
In cryptography, NUSH is a block cipher invented by Anatoly Lebedev and Alexey Volchkov for the Russian company LAN Crypto. It was submitted to the NESSIE project, but was not selected.
KZIQ-FM is a commercial radio station that is licensed to Ridgecrest, California. Owned by Adelman Broadcasting, it broadcasts a hot adult contemporary format, providing music and local news and information to the Indian Wells Valley.
Christian Holtermann Knudsen was a Norwegian typographer, newspaper editor, publisher, trade unionist and politician for the Norwegian Labour Party. He is known as chairman of his party in three non-consecutive periods, and also founded what would become the main party newspaper. He served three terms in the Norwegian Parliament.
Non-contact atomic force microscopy (nc-AFM), also known as dynamic force microscopy (DFM), is a mode of atomic force microscopy, which itself is a type of scanning probe microscopy. In nc-AFM a sharp probe is moved close to the surface under study, the probe is then raster scanned across the surface, the image is then constructed from the force interactions during the scan. The probe is connected to a resonator, usually a silicon cantilever or a quartz crystal resonator. During measurements the sensor is driven so that it oscillates. The force interactions are measured either by measuring the change in amplitude of the oscillation at a constant frequency just off resonance or by measuring the change in resonant frequency directly using a feedback circuit to always drive the sensor on resonance.
The Knudsen paradox has been observed in experiments of channel flow with varying channel width or equivalently different pressures. If the normalized mass flux through the channel is plotted over the Knudsen number based on the channel width a distinct minimum is observed around . This is a paradoxical behaviour because, based on the Navier–Stokes equations, one would expect the mass flux to decrease with increasing the Knudsen number. The minimum can be understood intuitively by considering the two extreme cases of very small and very large Knudsen number. For very small Kn the viscosity vanishes and a fully developed steady state channel flow shows infinite flux. On the other hand, the particles stop interacting for large Knudsen numbers. Because of the constant acceleration due to the external force, the steady state again will show infinite flux.
Lead magnesium niobate is a relaxor ferroelectric. It has been used to make piezoelectric microcantilever sensors.

Knudsen's Second Cabinet was the government of Norway from 31 January 1913 to 21 June 1920, led by prime minister Gunnar Knudsen. It was a Liberal Party minority government. It was formed following Jens Bratlie's defeat in the 1912 election.
Thomas George Thundat is an Indian-American scientist. He is currently the SUNY Distinguished Professor and a SUNY Empire Innovation Professor of Chemical & Biological Engineering at the University at Buffalo. Thundat conducts research in the field of nanosensors and microcantilevers.
