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.,.

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.

A series of phosphors Ba0.955Al2Si2-x GexO8:Eu2+ (x=0.0-1.0) were prepared via solid-state reaction in weak reductive atmosphere. The lattice positions and the luminescent mechanism of Eu2+ in the host are discussed. The effects of Ge4+-substitution on the host lattice and spectral properties are also investigated. The results show that complete solid solution is formed in the whole range of x =0.0-1.0 while Ge4+ enters BaAl2Si2O8 lattice and substitute Si4+. The lattice parameters (a, b, c, β) and unit cell volume of phosphors Ba0.955Al2Si2-x GexO8:Eu2+ (x=0.0-1.0) increase linearly as Ge4+ content increases in the phosphors. A broad excitation spectrum consists of four excitation bands, which locate between 230 nm and 400 nm, and the maximum emission wavelength is at 332 nm. The FWHM of the apparent excitation peak is narrowed from 93 nm to 80 nm. The broad and asymmetric emission spectrum is between 375 nm and 600 nm and apparent peak is at 434 nm, which can be fitted by two peaks at 422 nm and 456 nm. The distance between Eu and O is shortened due to Si4+ is replaced by Ge4+. The crystal field of the emitting center Eu2+ is enhanced. The splitting of 5d orbital levels is enhanced and the lowest emission level is expanded to lower region, and two fitted peaks are red shifted.

Data warehouse is a subject-oriented, integrated, stable and time-variant data collection which can be applicable in decision analysis. In a background of university teaching administration, this paper takes as the research object the data accumulated in teaching administration system over the years, primarily probes into the building of data warehouse for employment management and, by using the tool of OLAP, conducts the multi-dimensional analysis on the feedback data on graduate employment provided by the employers, in a hope of supporting the middle-level teaching administrative personnel in universities to make decisions. © (2014) Trans Tech Publications, Switzerland.
