Abstract: The present disclosure relates generally to a process for producing polymer fibers, typically polyacrylonitrile-based fibers, the properties of which are controlled by certain parameters of the process, such as the amount of jet stretch, the amount of wet stretch, and the amount of hot stretch employed. The present disclosure also relates to a process for producing carbon fiber from such polymer fibers.

Abstract: The present disclosure relates to a process for producing one or more carbon fiber precursor fibers, particularly by spinning a polymer solution, wherein the polymer has a polydispersity (PDI) of less than or equal to 2, in a coagulation bath with a jet stretch of about 5 to about 60. The one or more carbon fiber precursor fibers produced may be used for producing carbon fiber, typically carbon fiber used in manufacturing composite materials.

Abstract: The present disclosure relates to the production of polyacrylonitrile-based polymers with high conversion by a process comprising reacting acrylonitrile with at least one comonomer in the presence of a radical initiator in a liquid medium, wherein the radical initiator is present in an amount of from about 0.6 wt % to about 1.8 wt %, relative to the amount of acrylonitrile, and wherein no chain transfer agent is present. The polyacrylonitrile-based polymers produced may be used for producing carbon fiber, typically carbon fiber used in manufacturing composite materials.

Abstract: A polymer comprising repeating units derived from a first monomer, typically acrylonitrile, and repeating units derived from a second monomer different from the first monomer, wherein the second monomer is a compound comprising an ethylenically unsaturated organic anion and an organic cation containing a C?N imine group; a process for producing carbon fibers using the said polymer; and carbon fibers made therefrom, are described herein.

Abstract: The present disclosure relates to a process for producing carbon fibers utilizing a salt of an organic cation containing C?N imine group, and carbon fibers produced by such process.

Abstract: A symbol cipher system. The system has a symbol cipher application for execution on a digital platform. The symbol cipher application has: a first group of symbol components; a first range of code entry fields; a cipher correlation table. The cipher correlation table correlates the first group of symbol components to a first range of language characters. The first group of symbol components can be entered into the first range of code entry fields for registration of a symbol information item in an application database.

Abstract: A resource component for a game system. The resource component has a game play structure. It also has a linking mechanism. The linking mechanism is arranged about the game play structure. During play of the game, the linking mechanism dictates a gameplay condition. This gameplay condition is the availability of the game play structure to be included into the game system by linking to opposing resource components already present in the game play system. The game system is build around a central component.

Abstract: According to various illustrative embodiments of the present invention, a method and system for gathering per-frame image statistics in a real-time visual simulation comprises rendering a scene image in a frame of the real-time visual simulation with contents of a frame buffer copied to a texture comprising a plurality of texels, reducing resolution of the texture comprising the plurality of texels using a vertex shader producing a reduced resolution texture of the scene image, and collecting preliminary data on each texel of the reduced resolution texture of the scene image using a fragment shader operating on a respective fragment.
