Håkon Wium Lie (born July 26, 1965) is a Norwegian web pioneer, a standards activist, and the chairman of YesLogic, developers of Prince CSS-based PDF rendering software. [1] [2] He is best known for developing Cascading Style Sheets (CSS) while working with Tim Berners-Lee and Robert Cailliau at CERN in 1994.
In computer science, fractional cascading is a technique to speed up a sequence of binary searches for the same value in a sequence of related data structures. The first binary search in the sequence takes a logarithmic amount of time, as is standard for binary searches, but successive searches in the sequence are faster.
Selectivity, also known as circuit breaker discrimination, is the coordination of overcurrent protection devices so that a fault in the installation is cleared by the protection device located immediately upstream of the fault.
Since cascading two n th-order Butterworth filters will give a (2n) th-order Linkwitz–Riley filter, theoretically any (2n) th-order Linkwitz–Riley crossover can be designed. However, crossovers of order higher than 4 may have less usability due to their complexity and the increasing size of the peak in group delay around the crossover ...
HTML is a markup language that defines the structure and presentation of web pages. It is one of the core technologies of the World Wide Web, along with CSS and JavaScript. HTML allows creating and formatting text, images, links, tables, forms, and other elements on a web page. Learn more about the history, syntax, and features of HTML on Wikipedia.
The New York City blackout of 1977 was an electricity blackout that affected most of New York City on July 13–14, 1977. [3] [4] The only unaffected neighborhoods in the city were in southern Queens (including neighborhoods of the Rockaways), which were part of the Long Island Lighting Company system, as well as the Pratt Institute campus in Brooklyn, and a few other large apartment and ...
Wafering is the process by which a silicon crystal is made into wafers.This process is usually carried out by a multi-wire saw which cuts multiple wafers from the same crystal at the same time.
Air shower formation in the atmosphere. First proton collides with a particle in the air creating pions, protons and neutrons. The air shower is formed by interaction of the primary cosmic ray with the atmosphere, and then by subsequent interaction of the secondary particles, and so on.
