Three extraction parameters including time, material to solvent ratio, and temperature for the yield of Phyllanthus urinaria polysaccharides were optimized by response surface methodology. The results revealed that optimal process was time 5.3 h, 93 °C, ratio 1:47 g/mL, under which polysaccharide 6.40%; three had significant effect on yield, influence greatest lowest. antioxidant activity test ...

Most rare earth elements (REEs) are critical materials of extreme prominence. Because their criticality, convalescence into metal from oxide (REO) and recycling end-of-life essential for the proficient use safeguard natural resources. With pyrometallurgical approaches using potential versus partial oxidation pressure (E-pO2-) diagrams, conditions making neodymium established by which REOs disso...

This paper investigates the realization of optimal lter bank-based cepstral parameters. The framework is the Discriminative Feature Extraction method (DFE) which iteratively estimates the lter-bank parameters according to the errors that the system makes. Various parameters of the lter-bank, such as center frequency, bandwidth, gain are optimized using a string-level optimization and a frame-le...

Automatic speech emotion recognition is a process of recognizing emotions in speech. This has wide applications in the area of phsycatrics help and in robotics’he human computer interaction the challenging area of research. Any effective HCI system has two sections Training and testing. The techniques used in the system are feature extraction and classification. This paper focuses on the brief ...

− A new trend in the design of fuzzy rulebased systems is the use of evolutionary multiobjective optimization (EMO) algorithms. This trend is observed in various areas in machine learning. EMO algorithms are often used to search for a number of Pareto-optimal non-linear systems with respect to their accuracy and complexity. In this paper, we first explain some basic concepts in multiobjective o...

This paper presents a new method to extract functionally equivalent structures from logic netlists. It uses a fast functional regularity extraction algorithm based on structural equivalence. The goal of the proposed algorithm is the speedup of logic optimization of large circuits by reusing functionally equivalent structures of the design. It is particularly suited for circuits containing a lar...

to extract active components from the traditional Chinese medicine Polygonum cuspidatum using a trans-resveratrol imprinted polymer. Good separation and purification of trans-resveratrol and emodin from the Polygonum cuspidatum extract are achieved after condition optimization. The extraction recoveries are 83% and 99% for trans-resveratol and emodin, respectively. The results show that the mol...

Ancient DNA analyses rely on the extraction of the tiny amounts of DNA remaining in samples that are hundreds to tens of thousands of years old. Despite the critical role extraction efficiency plays in this field of research, no study has comprehensively compared ancient DNA extraction techniques to date. There are a wide range of methods currently in use, which rely on such disparate principle...

MOTIVATION It is attempted to improve the speed and flexibility of protein motif identification. The proposed algorithm is able to extract both rigid and flexible protein motifs. RESULTS In this work, we present a new algorithm for extracting the consensus pattern, or motif, from a group of related protein sequences. This algorithm involves a statistical method to find short patterns with hig...

Microextraction techniques, especially dynamic techniques like in-tube extraction (ITEX), can require an extensive method optimization procedure. This work summarizes the experiences from several methods and gives recommendations for the setting of proper extraction conditions to minimize experimental effort. Therefore, the governing parameters of the extraction and injection stages are discuss...
