Pulse (app)
LinkedIn Pulse was an app for Android,iOS and HTML5 browsers, originally released in 2010. The app, in its original incarnation, was deprecated in 2015 and integrated into LinkedIn.
History
Pulse was originally released in May 2010 for the Apple iPad. The app was created by Ankit Gupta and Akshay Kothari (two Stanford University graduate students) as part of a course at the Institute of Design. The company they formed, Alphonso Labs, was one of the first to use Stanford's business incubator SSE Labs. Pulse received positive reviews for its easy to use interface.
On 8 June 2010, the app was temporarily removed from the App Store hours after it was mentioned by Apple co-founder Steve Jobs at WWDC 2010, because The New York Times complained to Apple about the app pulling content from their feed, even though that feed was in use by other apps in the App Store. The app was approved once again and restored to the App Store later the same day after removing the The New York Times feed.
Pulse (physics)
In physics, a pulse is a single disturbance that moves through a medium from one point to the next point.
Pulse Reflection
Consider a pulse moving through a medium - perhaps through a rope or a slinky. When the pulse reaches the end of that medium, what happens to it depends on whether the medium is fixed in space or free to move at its end. For example, if the pulse is moving through a rope and the end of the rope is held firmly by a person, then it is said that the pulse is approaching a fixed end. On the other hand, if the end of the rope is fixed to a stick such that it is free to move up or down along the stick when the pulse reaches its end, then it is said that the pulse is approaching a free end.
Free End
A pulse will reflect off a free end and return with the same direction of displacement that it had before reflection. That is, a pulse with an upward displacement will reflect off the end and return with an upward displacement.
This is illustrated by figures 1 and 2 that were obtained by the numerical integration of the wave equation.
Pulse (2001 film)
Pulse, known in Japan as Kairo (回路), is a 2001 Japanese horror film directed by Kiyoshi Kurosawa. The film is based on his novel of the same name. The film was screened in the Un Certain Regard section at the 2001 Cannes Film Festival. The movie was well-received critically and has a cult following. An American remake, also titled Pulse, debuted in 2006 and spawned two sequels.
Plot
The plot centers on ghosts invading the world of the living via the Internet. It features two parallel story lines.
First Story
The first story involves a young woman named Kudo Michi (Kumiko Aso) who works at a plant sales company. She has recently moved to the city and her main friends are her three colleagues, Sasano Junko, Toshio Yabe and Taguchi. At the start of the film, it appears Taguchi has been missing for some days working on a computer disk. Michi goes to visit his apartment and finds him distracted and aloof; in the middle of their conversation, he casually makes a noose, leaves and hangs himself. Michi and her colleagues inspect the computer disk he left behind and discover it contains an image of Taguchi staring at his own computer monitor, which is displaying an image of Taguchi staring at his computer monitor, creating an endless series of images. In the other monitor on his desk, Michi and her friends discover a ghostly face staring out into Taguchi's room.
Surface
In mathematics, specifically, in topology, a surface is a two-dimensional, topological manifold. The most familiar examples are those that arise as the boundaries of solid objects in ordinary three-dimensional Euclidean space R3, such as a sphere. On the other hand, there are surfaces, such as the Klein bottle, that cannot be embedded in three-dimensional Euclidean space without introducing singularities or self-intersections.
To say that a surface is "two-dimensional" means that, about each point, there is a coordinate patch on which a two-dimensional coordinate system is defined. For example, the surface of the Earth resembles (ideally) a two-dimensional sphere, and latitude and longitude provide two-dimensional coordinates on it (except at the poles and along the 180th meridian).
The concept of surface finds application in physics, engineering, computer graphics, and many other disciplines, primarily in representing the surfaces of physical objects. For example, in analyzing the aerodynamic properties of an airplane, the central consideration is the flow of air along its surface.
Computer representation of surfaces
In technical applications of 3D computer graphics (CAx) such as computer-aided design and computer-aided manufacturing, surfaces are one way of representing objects. The other ways are wireframe (lines and curves) and solids. Point clouds are also sometimes used as temporary ways to represent an object, with the goal of using the points to create one or more of the three permanent representations.
Open and closed surfaces
If one considers a local parametrization of a surface:
then the curves obtained by varying u while keeping v fixed are sometimes called the u flow lines. The curves obtained by varying v while u is fixed are called the v flow lines. These are generalizations of the x and y lines in the plane and of the meridians and circles of latitude on a sphere.
Open surfaces are not closed in either direction. This means moving in any direction along the surface will cause an observer to hit the edge of the surface. The top of a car hood is an example of a surface open in both directions.
Surface (Surface album)
Surface is the debut self-titled studio release from the popular late-eighties soul trio. Three years after releasing the heavenly midtempo boogie track "Falling in Love" on Salsoul, Surface released their first album self-produced and released in 1986 on Columbia Records. The album peacked number 11 at Billboard "R&B albums" chart and number 55 at Billboard Top 200 albums chart. At the same time hit single "Happy" peaked number 2 at Billboard Hot R&B/Hip-Hop Singles & Tracks. The other song, "Lately" peaked at number 8 on the Billboard singles chart.
