In order to improve the recognition accuracy of seed cotton foreign fibers, a study on identification method in hyper-spectral images based on Minimum Noise Fraction (MNF) was proposed ,which was applied to feature extraction to reduce the dimension of hyper-spectral images. This method reduced the numbers of hyper-spectral data, lessened the images noise to the minimum , but also decreased the...

The kinetics of the extraction of tea seed oil with supercritical CO2 was studied. A kinetic model of the extraction of tea seed oil using supercritical CO2 was developed on the basis of the differential mass balance to simulate the extraction process. The model could simulate the distribution of the solute concentration in CO2 inside the extraction bed as a function of extraction time and heig...

In this study, microscale fermentations were conducted on Vitis vinifera L. cv. Merlot. Five treatments were established varying from 0-100% crushed fruit (25% increments x 5 replicates). Caps were kept submerged throughout the experiment, and fermentation temperatures were maintained at 25 degrees C. Samples were collected throughout fermentation and from the free run and press wine at the tim...

This study was designed to examine the nutritional composition, antioxidant activity and medium lethal concentration (LC50 value) of Tamarindus indica L. pulp and seed extracts in vitro. The extraction was set at 40◦C, 60◦C and 100◦C for 12 hours, 6 hours and 15 minutes respectively to determine the optimum extraction parameter whereas the anti-oxidant activity of the extracts was measured usin...

this study was carried out to determine the effect of seed growing regions and loading speed on some mechanical properties of castor seed. these properties are used to design and improve related machines such as expeller that are used for extraction of oil from castor seed. mechanical properties of castor seed were expressed in terms of rupture force and energy, bio-yield force, apparent modulu...

We present a novel context pattern induction method for information extraction, specifically named entity extraction. Using this method, we extended several classes of seed entity lists into much larger high-precision lists. Using token membership in these extended lists as additional features, we improved the accuracy of a conditional random field-based named entity tagger. In contrast, featur...

Recent approaches to relation extraction following the distant supervision paradigm have focused on exploiting large knowledge bases, from which they extract substantial amount of supervision. However, for many relations in real-world applications, there are few instances available to seed the relation extraction process, and appropriate named entity recognizers which are necessary for pre-proc...

The seed lipid of Nitraria tangutorum was extracted by supercritical carbon dioxide extraction, microwaveassisted reflux extraction, ultrasound-assisted extraction, or solvent reflux extraction. The experimental parameters of supercritical carbon dioxide extraction including pressure, temperature, particle size, and extraction time were investigated. A facile and sensitive method for the simult...
