Bartholomew Henry "Bart" Allen II is a fictional superhero in the DC Comics Universe. Allen first appeared as the superhero Impulse, a teenage sidekick of the superhero the Flash, before later on becoming the second hero known as Kid Flash. The character first made a cameo appearance in The Flash #91 in 1994, while his first full appearance in issue #92, and appeared as the lead character in Impulse (1995–2002) and The Flash: The Fastest Man Alive (2006–2007). In the latter series, the character became the fourth hero to assume the identity of The Flash. Bart also prominently features in the superhero team titles Young Justice and Teen Titans. As the Flash, Bart was also a core character in 10 issues of Justice League of America.

As first conceived by writers, Bart was born in the 30th century to Meloni Thawne and Don Allen, and is part of a complex family tree of superheroes and supervillains. His father, Don, is one of the Tornado Twins and his paternal grandfather is Barry Allen, the second Flash. His paternal grandmother, Iris West Allen, is also the adoptive aunt of the first Kid Flash, Wally West (Bart's first cousin once removed). Additionally, Bart is the first cousin of XS, a Legionnaire and daughter of Dawn Allen. On his mother's side, he is a descendant of supervillains Professor Zoom and Cobalt Blue as well as the half-brother of Owen Mercer, the second Captain Boomerang. In addition to these relatives, he had a supervillain clone known as Inertia.

Flash is a science fiction novel by L. E. Modesitt published in 2004.

Plot introduction

Flash is set in a future Earth of unspecified year; most likely 24th century as in its predecessor Archform: Beauty. Humanity is still recovering from environmental disasters of the 21st century, but technology provides enough material resources for everyone. Earth's old nations have merged into continental governments - such as NorAm, United Europe, and Sinoplex - many of which are partially or wholly under the sway of various multinational corporations. Various wars are in progress, including an independence movement of colonists on Mars.

The protagonist is Jonat DeVrai, a talented market research consultant and former Marine Corps officer who happens to have retained nanite combat enhancements that should be removed from retiring soldiers. As usual in Modesitt's books, DeVrai does not seek power; he is forced to exercise it because of others' attempts to use him in their designs to gather power to themselves.

The ICT 1301 and its smaller derivative ICT 1300 were early business computers from International Computers and Tabulators. Typical of mid-sized machines of the era they used core memory, drum storage and punched cards, but they were unusual in that they were based on decimal logic instead of binary.

The 1301 was designed by an ICT and GEC joint subsidiary, Computer Developments Limited (CDL) at GEC's Coventry site.

The 1301 was the main machine in the line. Its main memory came in increments of 400 words of 48 bits (12 decimal digits) plus two parity bits. The maximum size was 2,000 words. It was the first ICT machine to use core memory.

Backing store was magnetic drum and optionally one inch, half inch or quarter inch wide magnetic tape. Input was from 80 column punched cards and optionally 160 column punched cards and punched paper tape. Output was to 80 column punched cards, line printer, and optionally to punched paper tape.

The machine ran at a clock speed of 1 MHz and its arithmetic logic unit (ALU) operated on data in a serial-parallel fashion—the 48-bit words were processed sequentially four bits at a time. A simple addition took 21 clock cycles; hardware multiplication averaged 170 clock cycles per digit; and division was performed in software.
