Tokamak

A tokamak (Russian: токамак) is a device that uses magnetic field to confine plasma in the shape of a torus. Achieving a stable plasma equilibrium requires magnetic field lines that move around the torus in a helical shape. Such a helical field can be generated by adding a toroidal field (traveling around the torus in circles) and a poloidal field (traveling in circles orthogonal to the toroidal field). In a tokamak, the toroidal field is produced by electromagnets that surround the torus, and the poloidal field is the result of a toroidal electric current that flows inside the plasma. This current is induced inside the plasma with a second set of electromagnets.

The tokamak is one of several types of magnetic confinement devices, and is one of the most-researched candidates for producing controlled thermonuclear fusion power. Magnetic fields are used for confinement since no solid material could withstand the extremely high temperature of the plasma. An alternative to the tokamak is the stellarator.

List of minor DC Comics characters

Throughout its history, DC Comics has introduced many characters, including numerous minor characters. These characters range from supporting characters, heroes and villains that appear infrequently, to characters that only take part in a single story.

A

Airstryke

Airstryke is a villain in the DC Universe.

Within the context of the stories, William Kavanagh was given the ability to transform into a pterodactyl/man hybrid by a weapons company Meta/Tech and took the name Airstryke. Count Viper took advantage of these new abilities and used Airstryke to distract Hawkman while Viper tried to take command of the Justice League and thus the world. Airstryke and Viper were soon defeated and Airstryke was sent to Belle Reve Prison. He remained here until he was freed by Neron and was given the chance to sell his soul along with numerous other villains. Airstryke chose not to sell his soul and continued his life of crime. Eventually, Airstryke was returned to prison where he became a victim of Joker's Joker gas. Again, he was defeated and returned to prison. This time he was sent to the Slab. During his stay, Brother Blood attempted to break all the villains out of the prison so they could assist him on his mission. Airstryke was the first to question Blood on his plan. Brother Blood then shot and killed Airstryke for his hubris.

Tokamak (software)

The Tokamak Game Physics SDK is an open-source physics engine.

At its beginnings, Tokamak was free for non commercial uses only. Since May 2007, it has become open sourced under a BSD License. Now it can be used under BSD or Zlib license, in order to make the source code exchange with other physics engine possible.

Features

Tokamak features a unique iterative method for solving constraints. This is claimed to allow developers to make trade-offs between accuracy and speed and provides more predictable processor and memory usage. Tokamak's constraint solver does not involve solving large matrices, thereby avoiding memory bandwidth limitations on some game consoles.

The SDK supports a variety of joint types and joint limits and a realistic friction model. Tokamak is optimized for stacking large numbers of objects - a frequently requested feature by game developers. Tokamak provides collision detection for primitives (box, sphere, capsule), combinations of primitives, and arbitrary static triangle meshes. Lightweight 'rigid particles' provide particle effects in games at minimal cost.
