structural and physical properties of filament yarns melt-spun from pp/ldpe blend before and after false-twist texturing
nowadays, polymer blends usages increase more and more in order to produce materials with better properties. according to many research works, the blends of polyolefins have shown industrial importance. the purpose of this project was to carry out some investigations on fibers melt spun from the polypropylene and low density polyethylene blends. pp and ldpe are immiscible. pp/ldpe blend filamen...
متن کاملInvestigating the Effect of False Twist Texturing Process on the Color Coordinates Variation of Spun-dyed Polyester Filament Yarns
Correspondence to: Mohammad Amani Tehran email: [email protected] ABSTRACT In this study, color coordinates variation of spundyed polyester filament yarns subjected to the false twist texturing process was investigated. Furthermore, the effect of different processing parameters including D/Y ratio, twist, heater temperature, texturing speed, overfeed, the draw ratio and intermingling process on t...
متن کاملFalse Data Identification Method Based on Watermarking
The vulnerability of sensor nodes make the sensor network faces enormous security challenges. Attackers can inject false data to the network by capturing the normal nodes, by which the attackers can not only to mislead the data collection center to make the wrong decisions, but also can run out the energy of the nodes which forwarding the data. In order to cope with false data injection attack,...
متن کاملImage Denoising using TWIST Method
Most advancement in image de-noising algorithms are involving relatively poor numbers of patches and exploiting its similarity. These patch-based methods are completely based on matching of patches and their performance is restricted by the ability to dependably find suitably parallel patches. As number of patches grows, studies show that a point of retreating returns is reached where the perfo...
متن کاملThe false-positive to false-negative ratio in epidemiologic studies.
The ratio of false-positive to false-negative findings (FP:FN ratio) is an informative metric that warrants further evaluation. The FP:FN ratio varies greatly across different epidemiologic areas. In genetic epidemiology, it has varied from very high values (possibly even >100:1) for associations reported in candidate-gene studies to very low values (1:100 or lower) for associations with genome...
