Design and Implementation of Examination and Approval System for Financial Businesse Platform

随着生产力发展水平的不断提高，计算机效能与时俱进，互联网应用发展无处不在的走进我们的生活，而计算机技术成为处理信息的主要手段。从目前银行业整体分析，已经初步完成了信息化建设的初步过程，各个业务领域都有了信息化系统的支持。虽然从表面上看，信息化系统已经覆盖了银行大部分的业务范围，但是其存在的问题也逐步显现出来，各个系统有如一个个孤岛，产生的数据并不能为其他系统所使用，所以数据并没有产生更大的价值。 未来信贷流程的建设的关注点已不在于单单关注对公信贷审批领域内部审批的过程，也需要更加关注对公信贷流程的上下游系统的数据，以及对公信贷流程系统在整个银行项目群中所起的作用，比如，如何与客户关系管理系统...With productive forces develop and computer performance advances with the times, Internet applications have come into our life everywhere. And computer technique has been the main way to process information. From the whole analysis, current banking sector has finished the initial process of information-based construction, which makes information-based system supports in each business area.

Nonlinearity of interfaces and force transmission of bolted flange joints under impact loading

Vibration of flange joints and force transmission characteristics of connection interfaces are important due to concerns over the structural strength and signal identification in engineering structures such as missiles and rockets. However, nonlinear factors such as clearance, damping and discontinuous interfaces make it difficult to predict the responses under specific excitations such as shock impacts. This paper proposed a typical configuration of a bolted flange joint and investigated the response of vibration and dissipation of the joint under a series of impact loadings. The amplitude of excitation was 120 MPa, and the duration of the loading ranged from 20 mu s to 200 mu s. The excitations of high amplitude and frequency lead to a vibrational response coupled to a shock response of the joints. The connecting interfaces contributed to the distortion of the shockwave and changed its frequency, which can be characterized by the factor a. Those interfaces were also sources of energy dissipation, and their effect decreased as the frequency of excitation decreased. This methodology is helpful for predicting the local behavior of joints in a complex engineering structure under extreme conditions. (C) 2017 Elsevier Ltd. All rights reserved.</p

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel

JUNO sensitivity on proton decay p → ν K + searches*

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the $p\to \bar{\nu} K^+$ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar{\nu} K^+$ is 36.9% ± 4.9% with a background level of $0.2\pm 0.05({\rm syst})\pm$$0.2({\rm stat})$ events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is $9.6 \times 10^{33}$ years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
