It is well known that electronic bank whose development speed is so quick represents the future direction of bank industry. Although electronic bank can bring some convenient ways to us, it makes us have to face some realistic problems. In this paper, two aspects are demonstrated as follows: firstly, an improved fuzzy-AHP method is proposed. In real case, it is difficult to provide exact assessments by people. Therefore, triangular membership method is developed to improve acquirement of weights of each risk factor to avoid some qualitative methods such as expert scoring. Then, combining of the characteristic of risk assessment framework of bank information system, the proposed fuzzy-AHP method is applied to obtain weights of each risk factor of bank information system from 2011 to 2013 and further obtain the risk index of each risk factor. Secondly, based on this risk index and using classification properties of support vector machine to predict the risk. Finally, the experiment demonstrates the validity and applicability of the proposed method. Copyright © 2015, AIDIC Servizi S. r. l.,.

Data mining technology provides an effective research tool for us to process uncertain, noisy and implicit information. Rough set theory, as a kind of typical data mining algorithm, provides an effective tool for research on analysis and induction of inaccurate data, mining relations among data and discovering potential knowledge. The paper will establish a short-term load prediction model based on rough set theory. It utilizes rough to carry out attribute reduction for various historical data related to load, gets rid of those irrelative attribute to decision information and simplifies input variable so as to shorten the search space of neural network and improve the prediction performance.

We propose a collision detection algorithm based on combination of sphere and OBB. The bounding box is divided into upper and lower layers, the upper layer uses sphere to eliminate many disjoint objects, and the lower layer uses OBB to detect the collision between objects. The algorithm can save time and improve the efficiency of collision detection compared with the traditional single bounding box collision detection. © (2014) Trans Tech Publications, Switzerland.

Purpose. The issue of bankruptcy prediction and taking corresponding effect-reduction measures has become an important research topic in the field of economy. The article mainly studies the issue how to improve the support vector machine (SVM) based on prediction effect of the financial crisis early-warning model. Methodology. In view of the improved method of the kernel function exported Riemannian geometry structure, the financial crisis early-warning system based on the support vector machine (SVM) algorithm has been developed. Findings. The improved SVM model can effectively reduce the number of support vectors so that the model can feature better capacity for generalization, and provide a more accurate classification for unknown samples. The improved SVM model has increased the classification accuracy for the original training and testing sample set. Originality. An actual analysis on an improved algorithm for kernel function has been conducted based on the data information, according to the zoom level of data information adjustment feature mapping, giving the expression of the algorithm of Riemann measures on the polynomial kernel function. There has been no other literature describing the related study yet. Practical value. For the financial crisis early warning issue, provided its scale is not large, and in consideration of the enterprise's actual interests, it is often worthwhile to pursue a better prediction effect. In this case, the application of the SVM model with an improved kernel function is a good solution. © Qi Zhu, 2016.

As a new communications carrier in today's rapid development of modern technology, cell phone is a new media fusion, whose features include mobile newspaper, mobile radio, mobile Internet and other forms. Cell phone plays an important role in college students in daily life. From the influence on the college students by analyzing the internet function, this paper used the gray theory analysis and anonymous questionnaire to propose how to carry on Ideological and political education from the Internet management, publicity and online education, networking and moral cultivation Ideological and political educations. Finally this paper discussed how to establish a sound contemporary system of college students' political education into order to help students form a correct outlook on life, society and values. © 2013 Springer-Verlag.

Au and Ag nanoparticles are mainly employed in the fabrication of biosensors owing to their unique optical properties compared to other noble metal nanoparticles. Many biosensors are fabricated for the rapid detection of different analytes such as organic and inorganic molecules, biomolecules like DNA, proteins, biotoxins and pathogens. In this mini review we mainly discuss on the usage of Au and Ag nanoparticles for the fabrication of colorimetric, SERS and two photon based photoluminescence biosensors.

English, as a language for international communication, is essential in the world today. With the rapid change and development of the society as well as the change of the qualified people needed, university students have changed their learning needs and desires of English learning. Therefore, most universities own English-majors. The English teaching methods directly affect the achievement of the aims of English teaching and the satisfaction of the learners’ needs. We should analyze English major learners in Chinese universities and find the precondition for implementing the teaching plan and improving teaching methods. The university English teaching has emphasized on improving their practical application abilities of listening, speaking, reading and writing instead of the specific explanations of words, sentences and other basic language points. In this thesis, the writer will mainly research the present teaching and learning situation, explore learners’ needs, pros and cons of current teaching methods, and aim to find effective teaching methods to better suit the needs of university English Major Learners, supported by a survey designed by the author. Also, this thesis intends to find out what kind of teaching methods are most frequently adopted in the process of teaching, what kind of possible effective teaching approach might be greatly encouraged and used in the future, and accordingly give some suggestions for English educators and learners to choose effective ways of teaching and learning. © 2015 Taylor & Francis Group, London.
