Eh (programming Language)
''Eh'' ( or ) is a spoken interjection used in many varieties of English. The oldest ''Oxford English Dictionary'' defines ''eh'' as an "interjectional interrogative particle often inviting assent to the sentiment expressed." Today, while ''eh'' has many different uses, it is most popularly used in a manner similar in meaning to "Excuse me?", "Please repeat that", "Huh?", or to otherwise mark a question. It is also commonly used as an alternative to the question tag ''"right?"'', as a method for inciting a reply, as in "Don't you think?", "You agree with me, right?", as in, "It's nice here, eh?" (instead of "It's nice here, right?"). In the Americas, it is most commonly associated with Canada and Canadian English, though it is also common in England, Scotland, and New Zealand. It is also known in some American regions bordering Canada, including the area stretching from northern Wisconsin up to Michigan's Upper Peninsula. Similar interjections exist in many other languages, suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EHang
Guangzhou EHang Intelligent Technology Co. Ltd. is a company based in Guangzhou, China that develops and manufactures autonomous aerial vehicles (AAVs) and passenger AAVs which have entered service in China for aerial cinematography, photography, emergency response, and survey missions. History EHang announced the ''Ehang 184'', introduced at the Consumer Electronics Show in January 2016, as the world's first AAV capable of carrying passengers. The company announced plans with Dubai's Road & Transportation Agency in 2017 to launch an autonomous flying-taxi service starting in the summer of 2017, but didn't succeed. The company has also worked on a project with Nevada's Institute for Autonomous Systems for an AAV taxi that can transport a single passenger for up to 23 minutes with the EHang 184. In November 2018, an agreement was signed with the city of Lyon, France, to open a research center there. At the same time, a cooperation agreement was concluded with the Austrian ae ...

Hartree
The hartree (symbol: ''E''h), also known as the Hartree energy, is the measurement unit, unit of energy in the atomic units system, named after the British physicist Douglas Hartree. Its CODATA recommended value is = The hartree is approximately the negative electric potential energy of the electron in a hydrogen atom in its ground state and, by the virial theorem, approximately twice its ionization energy; the relationships are not exact because of the finite mass of the Atomic nucleus, nucleus of the hydrogen atom and Quantum electrodynamics, relativistic corrections. The hartree is usually used as a unit of energy in atomic physics and computational chemistry: for experimental measurements at the atomic scale, the electronvolt (eV) or the reciprocal centimetre (cm−1) are much more widely used.

Eh? (play)
''Eh?'' is a play by Henry Livings. Production history Original Production The play premièred at the Aldwych Theatre in London's West End, produced as part of the Royal Shakespeare Companys London Season, in October 1964 and featured David Warner, Donald Sinden and Janet Suzman and was directed by Peter Hall. Subsequent productions Two years later it opened Off-Broadway at the Circle in the Square Downtown on Bleecker Street on October 16, 1966. The production was directed by Alan Arkin, using the pseudonym "Roger Short". Arkin had stepped in as director about two weeks before it opened and after two directors had quit. He used a pseudonym because he was under contract to begin direction of '' Hail Scrawdyke!'' only a week later. The US production starred Dustin Hoffman as Valentine Brose, Alexandra Berlin as Betty Dorrick, Dana Elcar as Price, Carl Gabler as Aly, Joseph Maher as Reverend Mort and Elizabeth Wilson as Mrs. Murray. The play was the first major critical s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bottomless Pit (album)
''Bottomless Pit'' is the fifth studio album by experimental hip hop group Death Grips, released on May 6, 2016, through Third Worlds and Harvest Records. Background On October 21, 2015, the group uploaded a video to their YouTube page titled ''Bottomless Pit''. It features footage from 2013 of the late American actress Karen Black reciting lines from a film script that Death Grips drummer Zach Hill wrote months before her death. They also posted on their website and Facebook page that this would be the title for their upcoming fifth official studio album. Later, on December 16, the group posted a Twitter, tweet containing the phrase "it won't lit", eventually revealed to be a lyric from the ''Bottomless Pit'' track "BB Poison". On February 6, 2016, Death Grips released the song "Hot Head" from their upcoming album onto their SoundCloud and YouTube accounts. The cover art and tracklisting were then revealed on March 18, followed on April 19 by the announcement of a May 6 release ...

Air Nippon Network
, or A-net, was an airline based on the grounds of Tokyo International Airport in Ōta, Tokyo, Japan. It operated feeder services for parent Air Nippon, itself a subsidiary of All Nippon Airways (ANA). Its main base was New Chitose Airport. On October 1, 2010, Air Nippon Network, Air Next and Air Central were merged and rebranded as ANA Wings. History The airline was established in May 2001 to operate Air Nippon's local feeder routes from Tokyo and Sapporo. It started operations on 1 July 2002 using three Bombardier Dash 8 aircraft. In December 2003 4 more Dash 8s joined to replace Boeing 737 aircraft operated from Osaka by Air Nippon. In April 2004 Air Nippon Network was headquartered in Higashi-ku, Sapporo, Hokkaido. Air Nippon Network had 400 employees (at March 2007). Destinations Domestic destinations included: 運航路線 and 会社概要 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Exponential Hierarchy
In computational complexity theory, the exponential hierarchy is a hierarchy of complexity classes that is an exponential time analogue of the polynomial hierarchy. As elsewhere in complexity theory, “exponential” is used in two different meanings (linear exponential bounds 2^ for a constant ''c'', and full exponential bounds 2^), leading to two versions of the exponential hierarchy.Anuj Dawar, Georg Gottlob, Lauri Hella, Capturing relativized complexity classes without order, Mathematical Logic Quarterly 44 (1998), no. 1, pp. 109–122. This hierarchy is sometimes also referred to as the ''weak'' exponential hierarchy, to differentiate it from the ''strong'' exponential hierarchy. EH The complexity class EH is the union of the classes \Sigma^\mathsf_k for all ''k'', where \Sigma^\mathsf_k=\mathsf^ (i.e., languages computable in nondeterministic time 2^ for some constant ''c'' with a \Sigma^\mathsf_ oracle) and \Sigma^\mathsf_0 = \mathsf.

Reduction Potential
Redox potential (also known as oxidation / reduction potential, ''ORP'', ''pe'', ''E_'', or E_) is a measure of the tendency of a chemical species to acquire electrons from or lose electrons to an electrode and thereby be reduced or oxidised respectively. Redox potential is expressed in volts (V). Each species has its own intrinsic redox potential; for example, the more positive the reduction potential (reduction potential is more often used due to general formalism in electrochemistry), the greater the species' affinity for electrons and tendency to be reduced. Measurement and interpretation In aqueous solutions, redox potential is a measure of the tendency of the solution to either gain or lose electrons in a reaction. A solution with a higher (more positive) reduction potential than some other molecule will have a tendency to gain electrons from this molecule (i.e. to be reduced by oxidizing this other molecule) and a solution with a lower (more negative) reduction potential w ...

Early Helladic
Helladic chronology is a relative dating system used in archaeology and art history. It complements the Minoan chronology scheme devised by Sir Arthur Evans for the categorisation of Bronze Age artefacts from the Minoan civilization within a historical framework. Whereas Minoan chronology is specific to Crete, the cultural and geographical scope of Helladic chronology is confined to mainland Greece during the same timespan (c. 3200 – c. 1050 BC). Similarly, a Cycladic chronology system is used for artifacts found in the Aegean islands. Archaeological evidence has shown that, broadly, civilisation developed concurrently across the whole region and so the three schemes complement each other chronologically. They are grouped together as "Aegean" in terms such as Aegean art and, rather more controversially, Aegean civilization. The systems derive primarily from changes in the style of pottery, which is a benchmark for relative dating of associated artifacts such as tools and wea ...

Holden EH
The Holden EH is an automobile produced by Holden in Australia from 1963 to 1965. The EH was released in August 1963 replacing the Holden EJ series, and was the first Holden to incorporate the new red engine, with a seven main bearing crankshaft instead of the four main bearing crankshaft used in the grey engine. The newly released Red engine initially came in two capacities that being the 100hp 149 and the 115hp 179 cubic inch displacement. Standard issue on all models (except Premiers) was the 149 CID in either the manual or Hydramatic transmission. A lower compression 95 hp 149 was also available as an option, except on Premiers. The Premier models only received the larger 179 (HP cast block) and initially only with the Hydramatic transmission. The Hydramatic was a four-stage automatic transmission with a column shift although it effectively worked as a three-speed unit,except at full throttle.EH Holden Owners Manual, General Motors - Holden, 1964 (Provided with car at purch ...

Exception Handling
In computing and computer programming, exception handling is the process of responding to the occurrence of ''exceptions'' – anomalous or exceptional conditions requiring special processing – during the execution of a program. In general, an exception breaks the normal flow of execution and executes a pre-registered ''exception handler''; the details of how this is done depend on whether it is a hardware or software exception and how the software exception is implemented. Exceptions are defined by different layers of a computer system, and the typical layers are CPU-defined interrupts, operating system (OS)-defined signals, programming language-defined exceptions. Each layer requires different ways of exception handling although they may be interrelated, e.g. a CPU interrupt could be turned into an OS signal. Some exceptions, especially hardware ones, may be handled so gracefully that execution can resume where it was interrupted. Definition The definition of an excep ...
