Attapulgites (AT) were modified by coupling agent 3-(trimethoxysilyl) propyl methacrylate ( KH570 ). Then, the modified AT (MAT) and unmodified AT particles were compounded with Polypropylene (PP) to prepare PP/MAT and PP/AT composites respectively. Their structure and properties were characterized by mechanical testing, differntial scanning calorimetry (DSC) and Scanning electron microscopy (SEM). The results showed that the tensile strength of PP/MAT and PP/AT composites were both improved by filling of 1∼7 wt% AT particles. The izod impact strength of PP/MAT composites were increased obviously than that of PP/AT composites with AT content of 1∼7 wt%, and it attain the most at 1 wt% filler loading. The crystallization temperature of PP/MAT composites was increased than that of PP/AT composites and pure PP. The degree of supercooling was decreased indicates that the crystallization rate of polymer is improved. The crystallization rate of the PP phase is enhanced in the PP/MAT composites due to the introduction of homogeneous dispersed AT modified by KH570 and good interface adhesion between the AT and PP matrix.

In this paper, an adaptive interpolation method of digital image focusing on edge information is studied. The target is multi-level zoom ensuring image quality and keeping edge information. And this method is composed of three key models. (1) Accurate edge detecting model. Edge detecting model is the basic model to describe image features and the classic Canny edge detector is applied to get accurate image edge information. (2) Adaptive interpolation model. Kriging interpolation algorithm is used to interpolate zoom image using gray information and spatial distribution information of image. (3) adaptive image interpolation. Using Canny edge detector, original image is divided into edge and non edge region. And in image zoom process, the weighted neighborhood interpolation is applied to produce non edge pixels. Kriging interpolation is applied to produce edge pixels to Keep edge characteristics. Experiment is carried out to test the effectiveness and characteristics of this approach. Experimental results approve that it can realize multi-level zoom and keep edge information while image zoom out. Experimental results show the validity and practicability of the research method and it has good application potential. © 2014 IEEE. Source

With the popularity of the Internet, e-mail with its fast and convenient advantages has gradually developed into one of the important communication tools in people's lives. However, the problem of followed spam is increasingly severe, it is not only the dissemination of harmful information, but also waste of public resources. To solve this problem, the author proposed a mail filtering algorithm based on the feedback correction probability learning. The feedback correction probability training has less feedback learning data and use error-driven training in order to achieve a high classification effect. The experiment also tested the idea. © (2013) Trans Tech Publications, Switzerland. Source
