Potential of using plant proteins and chicken feathersfor cotton warp sizing

Two plant proteins, soyprotein and wheat gluten, and chicken feathers used to size cotton substrates provided sizing performance similar to starch and were also easily degraded in activated sludge. Sizing is an essential process to impart protection to warp yarns and increase weaving efficiency. Cotton yarns have traditionally been sized with starch, modified starch derivatives, CMC, poly vinyl...

Warp drive and causality.

Alcubierre recently exhibited a spacetime which, within the framework of general relativity, allows travel at superluminal speeds if matter with a negative energy density can exist, and conjectured that it should be possible to use similar techniques to construct a theory containing closed causal loops and, thus, travel backwards in time. We verify this conjecture by exhibiting a simple modific...

Shear-Warp Deluxe: The Shear-Warp Algorithm Revisited

Despite continued advances in volume rendering technology, the Shear-Warp algorithm, although conceived as early as 1994, still remains the world’s fastest purely software-based volume rendering algorithm. The impressive speed of near double-digit framerates for moderately sized datasets, however, does come at the price of reduced image quality and memory consumption. In this paper, we present ...

New Methods in WARP

The WARP[1] code is being developed and applied to simulate the creation and propagation of the high-current, space-charge dominated beams that are required for heavyion driven fusion energy (HIF). New methods and capabilities have recently been introduced into WARP, a multidimensional particle-in-cell code developed for the study of space-charge dominated beams. We describe: (a) a 2D3V “slice”...
