This paper proposes a new method of face image feature extraction, namely, the fuzzy 2DFLD (F2DFLD) based on the 2D fisher discriminant criterion and fuzzy set theory. In the proposed method, we calculate membership degree matrix by FKNN, then we incorporate the membership degree into the definition of the between-class scatter matrix and within-class scatter matrix and get the fuzzy between-cl...

Flavanols are a class of polyphenols that have become the focus much research because their medicinal properties. For this paper, new method to determine in nutraceutical samples was developed, based on solid-liquid extraction and further analysis by liquid chromatography. Analytes were recovered ultrasound-assisted extraction, using mixture methanol/water/hydrochloric acid (70:29:1, v:v:v) as ...

Fatty Liver Disease (FLD) is an increasing prevalent disease that can be reversed if detected early. Ultrasound is the safest and ubiquitous method for identifying FLD. Since expert sonographers are required to accurately interpret the liver ultrasound images, lack of the same will result in inter-observer variability. For more objective interpretation, high accuracy, and quick second opinions,...

The enormous power of modern computers has made possible the statistical modelling of data with dimensionality that would have made this task inconceivable only decades ago. However, experience in such modelling has made researchers aware of many issues associated with working in high-dimensional domains, collectively known as ‘the curse of dimensionality’, which can confound practitioners’ des...

The forming limit diagram (FLD) is a widely used tool to assess the formability of metal sheet [1]. current study aims investigate influence strain rate, material anisotropy and hardening on FLD Ti-6Al-4V predicted by well-known Marciniak-Kuczynski (M-K) method. tensile data quasi-static (8 10 -5 s -1 ), intermediate (0.5 ) dynamic experiments (approximately 1000 are available at three differen...

A single step analysis method for the quantification of 11 different aromatic compound in aqueous samples by use HPLC-FLD/DAD.

because of high strength to weight ratio, 6061 aluminum has many applications in different industries like automotive and aerospace industries and can help to reduction of fuel consumption. forming limit diagram (fld) is a useful method for sheet metal formability identification. whereas calculation of forming limit diagram by experimental tests is expensive and time consumption, in the present...

The double-yolked (DY) egg is quite popular in some Asian countries because it is considered as a sign of good luck, however, the double yolk is one of the reasons why these eggs fail to hatch. The usage of automatic methods for identifying DY eggs can increase the efficiency in the poultry industry by decreasing egg loss during incubation or improving sale proceeds. In this study, two methods ...
