Yi Jianzhong, Pi Jundan
The financing efficiency evaluation of small and medium-sized enterprises (SME) is fuzzy. The comprehensive fuzzy evaluation model of SMEs will be established by fuzzy evaluation method in this paper. The financing efficiency of such five different kinds of financing methods as internal financing, financing of stocking and bond, bank loan and private lending of SMEs will be analyzed in the terms of financing cost, fund utilization rate, financing risk, freedom degree of financing body and market maturity, and companies' overall financing efficiency will be accordingly analyzed, which will provide guidance for SMEs to make financing decisions.

Influence of Seismic Wave Frequency on Wave Passage Effect of Plane Frame 地震波频率对平面框架通波效应的影响
Wang Yingli, Liu Tielin, Liu Hong, Cui Xu
The plane frame structure of three-span, six-story reinforced concrete structure, is adopted to study whether wave passage effect should be considered in the seismic responses of frame structures or not. The influence factors of seismic wave's frequency and wave passage effect on the structure are studied. The earthquake responses of the frame structure to wave passage excitations and uniform excitations are computed respectively for the class III site seismic wave by using Midas Gen software. The results of column shear forces obtained from the wave passage excitations are compared with those of the uniform excitations. And the frequencies of seismic waves are analyzed. Numerical results showed that wave passage effect caused the shear force of the first-story column facing the seismic wave to increase remarkably for the plane frame structures. For the seismic waves with wave passage effect, the main peaks of frequency amplitude spectrum of seismic wave arise in low frequency domain.
以三跨六层钢筋混凝土结构平面框架结构为研究对象,研究框架结构在地震反应中是否应考虑波束效应。研究了地震波频率和穿越效应对结构的影响因素。采用Midas Gen软件分别计算了III类场地地震波下框架结构在通道激励和均匀激励下的地震反应。并与均匀激励下的柱剪力计算结果进行了比较。对地震波的频率进行了分析。数值计算结果表明,波浪通道效应使平面框架结构面对地震波的第一层柱剪力显著增大。对于具有过波效应的地震波,地震波频率幅值谱的主峰出现在低频域。

Remote Protection for Mobile Apps in Cloud Computing Environments 云计算环境下移动应用的远程保护
Sha Feng, Shuang Zhao, Shiduo Feng, Yanchao Zhang
Android app repackaging has become a serious problem currently. To protect apps from tampering, code obfuscation, watermarking and other techniques have been designed. However, most of these approaches could only provide inadequate protection. Meanwhile, it is possible to achieve remote tamper-resistance in recent, especially for networking apps, with the development of cloud computing technology and the spread of networks. In this paper, we propose a novel remote protection mechanism for mobile apps in cloud computing environments. In the proposed mechanism, the app should download and execute some code from the cloud when some important function is called. Tamper proofing code which could check the app is tampered or not is embedded in the downloaded code. Furthermore, the code can only run correctly one time and is continuous changing, which makes it difficult for an adversary to analyze and modify.
Android应用重新包装已经成为当前一个严重的问题。为了保护应用程序不被篡改,还设计了代码混淆、水印和其他技术。然而,大多数这些办法只能提供不足的保护。同时,近年来随着云计算技术的发展和网络的普及,实现远程防篡改成为可能,尤其是网络应用。在本文中,我们提出了一种新的云计算环境下移动应用程序的远程保护机制。在提议的机制中,当调用一些重要的函数时,应用程序应该从云中下载并执行一些代码。可以检查应用程序是否被篡改的防篡改代码嵌入下载的代码中。此外,代码只能正确运行一次,并且不断更改,这使得攻击者难以分析和修改。

Medical Image Registration Algorithm Based on Compressive Sensing and Scale-Invariant Feature Transform 基于压缩感知和尺度不变特征变换的医学图像配准算法
Y. Sa
A registration algorithm based on compressive sensing theory and SIFT(Scale-Invariant Feature Transform) is proposed. By the sparse feature representation methods, the feature vector of SIFT is extracted and the high-dimensional gradient derivative is decreased to low-dimensional sparse feature vector. Accordingly, Euclidean distance is introduced to compute the similarity and dissimilarity between feature vectors used for image registration and BBF(Best-Bin-First) data structure is used to avoid exhaustion. The experimental results show that the proposed algorithm has better performance than the traditional SIFT algorithm. Comparing with the current modified SIFT algorithms, the real-time performance of the proposed algorithm is improved obviously.
提出了一种基于压缩感知理论和SIFT(Scale-Invariant Feature Transform)的配准算法。通过稀疏特征表示方法提取SIFT特征向量,将高维梯度导数降为低维稀疏特征向量。因此,引入欧氏距离来计算图像配准所使用的特征向量之间的相似度和不相似度,并使用Best-Bin-First数据结构来避免耗尽。实验结果表明,该算法比传统的SIFT算法具有更好的性能。与现有的改进SIFT算法相比,该算法的实时性有明显提高。

Juli Li, Feng Wu, Huafeng Guo, Yingquan Li
An adjustable foaming machine that consisted of air feeding system, liquid feeding system, foaming device, and control system was designed to satisfy various demands on foam density and foam diameter in the preparation of foam concrete. The air-liquid ratio was adjusted by controlling the foaming liquid flow, and the adjustment of foam density was achieved. An adjustable single-foam tube structure was adopted to realize the controls of foam density and pore size by adjusting the packing density of the foaming medium in the foaming tube. By using the single chip as the digital processing core, the communication between single chip and frequency converter was established through the RS485 interface, thereby realizing the automatic control in the working process of the adjustable foaming machine. The experimental result indicated that the foaming process of this machine was stable and highly efficient, and foam density and foam diameter were easy to adjust and control, which improved the usability.
