The DC statement is used to name and enter constants into the object program.

One example is the axiom of dependent choice ( DC ).

For example, ZF + DC + BP is consistent, if ZF is.

It is also consistent with ZF + DC that every set of reals is Lebesgue measurable ; however, this consistency result, due to Robert M. Solovay, cannot be proved in ZFC itself, but requires a mild large cardinal assumption ( the existence of an inaccessible cardinal ).

ZF + DC + AD is consistent provided that a sufficiently strong large cardinal axiom is consistent ( the existence of infinitely many Woodin cardinals ).

* 1939 – DC Comics publishes its second major superhero in Detective Comics # 27 ; he is Batman, one of the most popular comic book superheroes of all time.

Abra Kadabra is the name of a DC Comics villain, who originally uses futuristic technology to create effects that appear magic to present-day people, and later gains actual magic powers.

A device that converts signals from one type to another ( for example, a light signal in photons to a DC signal in amperes ) is a transducer, a transformer, or a sensor.

Drain efficiency is the ratio of output RF power to input DC power when primary input DC power has been fed to the drain of an FET.

Based on this definition, the drain efficiency cannot exceed 25 % for a class A amplifier that is supplied drain bias current through resistors ( because RF signal has its zero level at about 50 % of the input DC ).

In this case the RF zero level is near the DC rail and will swing both above and below the rail during operation.

While the voltage level is above the DC rail current is supplied by the inductor.

There is a total of, ( double track ( as of 1998 )), of which are electrified, mainly at 3, 000 volts DC but with at 25 kV 50 Hz AC ( 2004 ) and all on standard gauge of.

Electrification is at 3 kV DC, with the exception of the new high-speed lines, and of two recently electrified lines in the south of the country which are at 25 kV AC.

** Luxembourg — no voltage change at the border ( the line Arlon-Luxembourg is at 3 kV DC and the line Gouvy-Luxembourg is at 25 kV AC )

Dr. Benjamin D. Santer ( born June 3, 1955 in Washington, DC, United States ) is a climate researcher at Lawrence Livermore National Laboratory and former researcher at the University of East Anglia's Climatic Research Unit.

When a metal wire is connected across the two terminals of a DC voltage source such as a battery, the source places an electric field across the conductor.

Direct current ( DC ) is the unidirectional flow of electric charge.

In direct current ( DC, also dc ), the flow of electric charge is only in one direction.

The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage.

In engineering or household applications, current is often described as being either direct current ( DC ) or alternating current ( AC ).

Within the United States Graffiti Artists such as Mike Giant, Pursue, Rime, Noah and countless others have made careers in skateboard, apparel and shoe design for companies such as DC Shoes, Adidas, Rebel8 Osiris or Circa Meanwhile there are many others such as DZINE, Daze, Blade, The Mac that have made the switch to gallery artists often times not even using their initial medium, spray paint.

In 2002, DC Comics introduced a villain named Onomatopoeia, an athlete, martial artist and weapons expert who often speaks sounds.

Risus ( Latin for “ laughter ”) is a comedy game ( often described by its creator as a " joke game ") and uses a cliché ( character class ) system inspired by the broad " career scale " skills in Greg Gorden's DC Heroes RPG ( Mayfair Games ), and later influenced by Atlas Games ' Over the Edge.

The late Max Hunter, while employing hydrogen fuel in the DC / X, often said that he thought the first successful orbital SSTO would more likely be fueled by propane.

Most VTVMs and FET-VMs handle DC voltage, AC voltage, and resistance measurements ; modern FET-VMs add current measurements and often other functions as well.

The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage.

The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage.

Although DC stands for " direct current ", DC often refers to " constant polarity ".

One story states that the term originated at the Willard Hotel in Washington, DC, where it was used by Ulysses S. Grant to describe the political wheelers and dealers who frequented the hotel's lobby to access Grant — who was often there to enjoy a cigar and brandy.

The add-on code is often one of the following: the last four digits of the box number ( e. g., PO Box 58001, Washington DC 20037-8001 ), zero plus the last three digits of the box number ( e. g., PO Box 12344, Chicago IL 60612-0344 ), or, if the box number consists of fewer than four digits, enough zeros are attached to the front of the box number to produce a four-digit number ( e. g., PO Box 52, Ambler PA 19002-0052 ).

The comics were scripted by Howard Chaykin, who had drawn several issues of the earlier DC title, and pencilled by Mike Mignola, whose Hellboy comic book often has a similar feel to Leiber's work.

Rectifiers have many uses, but are often found serving as components of DC power supplies and high-voltage direct current power transmission systems.

Turbo was often dubbed as " the Polish Iron Maiden ", while TSA played in a similar style to AC / DC.

Regardless, various " revised " DC Universe characters have often referenced a past event called " Crisis ".

In the popular comic by DC Comics, as well as three Batman movies ( 1966, 1989 and The Dark Knight ) and the TV series, The Joker is the supervillain nemesis of Batman and is often portrayed as having a rather " Dark and Twisted " jester-like sense of humor whose theme of practical jokes almost always holds death as the punchline during his " performances ".

They often collaborate with DC artist Richard Morel and produced a dance hit with his song " True ( The Faggot is You )".

In addition to writing and making appearances on behalf of the Downsize DC Foundation ( an organization he helped to co-found and for which he served as Director of Public Policy for a year and a half ), he hosted two weekly network radio shows, one on Saturdays dealing with politics, which he often called “ The Libertarian Conversation ” ( since listeners were encouraged to call in ), and the other on Sundays, called " The Money Show ", dealing with financial topics.

These mature readers comics, both those that became Vertigo and those that did not, often had the DC bullet printed in a smaller than usual size.

Marvel has also had many large crossover events which depicted an alternative universe, many springing from events in the X-Men books, such as Days of Future Past, the seminal Age Of Apocalypse, and 2006's House Of M. In addition the Squadron Supreme is a DC inspired Marvel Universe that has been used several times, often crossing over into the mainstream Universe in the Avengers comic.

Other differences are with plugs that match 1 / 4-inch or 6. 3mm jacks, 3. 5mm jacks, and banana jacks, with main DC power supply ( typically ± 15 V, but ranging from ± 18 V to ± 12 V for different manufacturers or systems ), with trigger or gate voltages ( Moog S-trigger or positive gate ), with typical audio signal levels ( often ± 5 V with ± 5 V headroom ), and with control voltages of volts / octave ( typically 1 V / octave, but in some cases 1. 2 V / octave.
