Authors: Li Hong Hai , Cheng Yang Yang
Published: August 2013

A three-dimensional computational fluid dynamics (CFD) simulation was performed to study the velocity distribution on membrane surface in membrane separation process, and the effect of face permeability, porous medium thickness, and pressure-jump coefficient of porous-jump model on membrane flux. The study shows that all the three factors have important impact on membrane flux. Membrane flux increases linearly with the increase of face permeability. When the membrane thickness is between 0.04~0.1mm, the membrane flux decreases with the increase of membrane thickness. The membrane flux decreases with the increase of pressure-jump coefficient. So that there must be a complex relationship between membrane flux and face permeability, porous medium thickness, and pressure-jump coefficient.

Authors: Ye Yong , Li Ming Yang , Xing Hai Ting
Published: August 2013

Polyphenol is a kind of active compound widely existed in many Chinese herbs, easily destroyed by oxygen and heat. Extraction and concentration are key steps to protect it from destruction, and the costly energy consumption steps in the process of herbs. In order to save energy and improve polyphenol quality, instantaneous ultrasonic extraction (IUE) and reverse osmosis (RO) concentration are evaluated in this paper. IUE and RO were used to extract polyphenol separately from herbs of Phyllantuus urinaria L, leaves of Camellia sinensis L and root of Salvia miltiorrhiza Bunge. Gallic acid, EGCG and Tanshinol, the main components of polyphenols, were determined by HPLC. Their content and energy consumption were compared to that by same time water boiling (10min) or 60min ultrasonic extraction and vacuum concentration. IUE increased 1-3 times or 1-5 times polyphenol content and saved 1 or 6 times energy consumption more than the same time water boiling or 60min ultrasonic extraction. Compared with vacuum vaporization to the same solid matter content (15%), RO increased 2 times polyphennol content and consumed 1/10 times energy and 1/5 times time. Combination of IUE and RO shortens process time, significantly improves polyphenol quality and saves energy. It will be the beneficial method for polyphenol extraction and concentration of Chinese herbs.

The face pose is corrected from the normal vector direction. This method is small amount of calculation and wide applicability. The experimental results show that the correction effect is good.

Published: August 2013

Missing value of dataset has become a challenging issue in data mining. Although there have been significant efforts to handle it, the methods to deal with missing values in neural networks are undeveloped. This article thus proposes an intelligent method to perform classification and regression in case of missing values. In particular, hybrid genetic algorithms and fast simulated annealing are used to predict them, and their results are further compared. The experimental results give rise to a valuable and deep insight into handling missing values in data mining application.

In the past few years many scientists have tried to develop models of networks and to investigate the mechanisms that determine the topology of complex networks. We define a class of graphs called (k,m)-dragon graphs and uniformly (k,m)-dragon graphs as referenced models of complex networks. These dragon graphs have some properties such as its admits (k,d)-odd-graceful labeling, graceful labellings, odd-graceful labellings and so on. In this paper, we proposed and defined the notion of some labelings of dragon graphs, the odd-graceful, graceful and total labellings of edges magic of these dragon graphs have been investigated in detail, and our methods can be algorithmic. Through the definition of dragon graphs and proofs of Theorems, we get some simple but usefulconclusions.

Published: August 2013

This paper proposes two complementary procedures for assessing the indoor global comfort: the first one, prevalently objective, is based on the acquisition of microclimate measured data and computed subjective values; the second one, that is purely subjective, uses a questionnaire drawn from the ISO/DP 10551 Recommendation. An application to some lecture-halls is here showed
Boundary Variable Precision Dominance-Based Rough Set Approach in Multicriteria Sorting Problems
Authors: Li Hong , Wang Guo Yin , Gou Guang Lei , Liu Wen
Published: August 2013

This paper provides a novel method of boundary variable precision dominance-based rough set approach (BVP-DRSA) to solve multicriteria sorting problem that differs from usual classification problems since it takes into account preference orders in the description of objects by condition and decision attributes. The major contribution of our BVP-DRSA method is that it combines variable precision and dominance-based rough set approach (DRSA). This approach is different from the dominance-based rough set approach (DRSA) because it takes boundary into account and can deal with boundary directly. Comparative experiments form datasets of UCI and empirical results shows that our BVP-DRSA is far more efficient than directly using already known classing algorithms and DRSA.

Published: August 2013

The nonlinear analysis of HRV index can effectively evaluate the drivers mental and physiological stress reaction during driving. By collecting drivers ECG signal on the Prairie Highway and based on nonlinear analysis of HRV, it is found the drivers Correlation Dimension (D2) changes significantly and has a strong negative correlation with driving time, and the regression model under the Prairie Highway environment has been built in this paper. Combining the difference test between the dynamic and static index, the study has concluded drivers sympathetic nerve activity decrease after continuous driving for 30min, and D2 is 2.034-2.593 after 110min.The complexity of drivers autonomic nervous system and the adjust ability of adapting to the environment decrease significantly on the Prairie Highway. These will offer the theoretical basis for monitoring driver fatigue and designing Prairie Highway.
