Optimal Control of Melt Spinning Processes

Effect of Melt Spinning Variables on the Structural Changes of Recycled and Bottle Grade Filament Yarn PET

TEM INVESTIGATION OF RAPIDLY SOLIDIFIED NDFEB HARD MAGNETIC MATERIAL

The surface condition and microstructure of near stoichiometric (Fe823Ndll.8B5.9) Nd-Fe-B alloy ribbons and the effect of melt spinning parameters were investigated using optical, scanning and transmission electron microscopes (SEM, TEM). The formation of gas pockets on the roll surface of the ribbons during melt spinning can prevent heat transform and result in local coarse grains. The local t...

Simulation of Carbonaceous Mesophases Micro-Textures

Carbonaceous mesophases are liquid crystalline precursor materials that can be spun into high performance carbon fibers using the conventional melt spinning process. Carbon fiber property optimization requires a better understanding of the principles that control the structure development during the fiber formation processes and the rheological processing properties. This work presents the elas...

New Cellulosic Materials Produced by Thermoplastic Processing of Silylcellulose

The application of melt spinning processes for the production of cellulosic fibres would be a significant sign of progress for economic and environmental reasons. A process for melt spinning of trimethyl-silycellulose (TMSC) was developed. Bis(trimethyl-)silylcarbamate (BSC) was found to be excellent for the silylation of cellulose due to good swelling and penetration into cellulose. The synthe...

Optimal Bidding Strategies of GENCOs in Day-Ahead Energy and Spinning Reserve Markets Based on Hybrid GA-Heuristic Optimization Algorithm

In an electricity market, every generation company (GENCO) attempts to maximize profit according to other participants bidding behaviors and power systems operating conditions. The goal of this study is to examine the optimal bidding strategy problem for GENCOs in energy and spinning reserve markets based on a hybrid GA-heuristic optimization algorithm. The heuristic optimization algorithm used...
