Design and Implementation of Bank Remote Centralized Authorization System
随着银行业务和信息技术的发展,银行系统的安全性和业务处理效率已提至很重要的位置。目前,现场授权在某些方面存在诸多问题且效率不高,缺乏可靠的审核及判断,在一定程度上已经不能满足银行业务发展的需要。建立远程集中授权系统,经办柜员将网点现场交易画面和业务交易凭证影像等需要授权的材料传输至后台远程授权中心,由后台远程授权中心人员通过判断审核材料是否完备最终进行业务授权,从而实现了对授权环节的实质性、专业化审核,可充分发挥远程集中授权系统在风险防控、规模作业方面的优势,有效提升了网点服务质量,提高了柜员的工作效率,降低了银行营运成本。在此情况下,尽快启动远程集中授权项目,并与影像处理平台、前端系统改造等...With the development of banking business and information technology, the safety of the banking system and business process efficiency has been to a very important position. At present, the authorization is in some ways has many problems and the efficiency is not high, and the lack of reliable audit judgment, to a certain extent, have already can't satisfy the needs of the development of banking bu...学位:工程硕士院系专业:软件学院_工程硕士(软件工程)学号:X201323232

From Spontaneity to Self-Consciousness: Disenchantment &Reconstruction of State Sovereignty
法学研究者应当区分“理科思维”和“工科思维”、“理论研究”与“规则研究”。与自然科学和社会科学中若干公认“硬科学”所遵循的“解释+预测”的理论研究路径不同,“理解+指引”应是法学理论研究的更优选择。对于特定的理论命题,前一路径要求所建立的理论能够以一定的精确程度对自然规律或社会规律提出“解释”,并且能够根据对系统的给定条件(输入值)推导后续变化和最终结果(输出值),从而实现一定程度的“预测”之功效。而在后一种理论路径中,“理解”的实现,需要研究者深度发掘历史,对理论命题宏大叙事的现状层层祛魅,尽量还原其真实意涵,从而使得对其进行与时俱进的更新成为可能;“指引”则要求研究者树立价值立场,对理论命...Legal researchers should be able to disguish “Scientific Thinking” from “Engineering Thinking”, and “Research of Theory” from “Research of Rules”. Different from the theoretical research approach of “explanation+prediction” commonly adopted by natural science and some “hard scientific disciplines” in social science, “comprehension+guidance” would probably be a better choice for carrying out theore...学位:法学博士院系专业:法学院_国际法学学号:1362011015352
Mortality Estimation Based on Change-point Detection of Principal Component Scores
Lee-Carter模型(简称经典LC模型)的问世是随机死亡率模型发展中的一个里程碑。然而经典LC模型的缺陷之一是其随机误差项的方差存在异质性,这会增加死亡率预测结果的不稳定性。基于主成分分析思想,以主成分得分为解释变量构建的对数中心死亡率回归模型(简称为经典PC模型)通过增加主成分的个数使得异方差问题迎刃而解。然而经典PC模型存着两个问题阻碍着其发展,一是经典PC模型中主成分得分的预测尚未出现较好的预测模型,二是经典PC模型中各主成分的人口学含义不够明确。 本文针对经典PC模型中存在的两个问题进行了研究,将多变点检测方法应用于人口死亡率预测中,并赋予了死亡率与其均值的波动的主要主成分人口学...The advent of the Lee-Carter model (referred to as the classical LC model) is a milestone in the development of the stochastic mortality model. However, one of the defects of the classical LC model is that the variance of its random error term is heterogeneous, which increases the instability of the mortality prediction results. Based on the principal component analysis, the logarithmic center mor...学位:经济学硕士院系专业:经济学院_统计学学号:1542014115200
The Financing and fund Management to the Fujian Highway: Problems and Solution
我国交通基础设施还较为薄弱,经济发展对交通运输的需求又十分迫切,而政府财力相对较弱,无法满足庞大的公路建设投资,建设资金不足与建设步伐加快的矛盾日益突出。近期的货币紧缩政策更让高速公路建设资金短缺,部分路段甚至出现停工等待资金到位的情况,因此探讨解决高速公路的建设资金问题尤为必要。本文针对高速公路投融资体制的特点,深入分析了当前社会经济形势对高速公路的影响,金融市场的融资现状,认为当前高速公路融资与资金管理中存在的不足和问题是:融资体制改革滞后、政府的支持力度不足、融资结构中存在金融风险、融资中存在的成本风险、现行融资方式难以适应山区公路建设需要,而分权式财务资金管理使得资金沉淀严重、利用效率...The nation’s highway transportation infrastructure is in physically and financially developing stage. The current approach to fund highway infrastructure development, which aims to create a nation-wide transportation network and support the continuously growing economy, is not able to address the serious challenges we face today. Inadequate transportation funding from all levels of government – as...学位:会计硕士院系专业:厦门大学与厦门国家会计学院会计硕士专业学位联合教育中心(MPACC)_会计硕士(MPACC)学号:X200515705

Research on 3D Strip Designing Method for Reinforced Concrete beam slab—without secondary beam
为了进一步探索完善钢筋混凝土梁板协同工作设计方法,在文献[13]、[14]、[35]、[36]、[37]系列研究的基础上,本文通过非线性有限元数值(ANSYS)模拟分析,对文献[36]、[37]提出的“三维条带法”膜效应系数、调幅系数作了必要的调整、修正和统一,使“三维条带法”分析的内力与非线性数值模拟更为接近,并分析了梁板膜效应系数的影响因素。此外分析还表明楼板支座负弯矩应为正弯矩的3~15倍,而非“边支承板”的1.5~2.5倍。文中还分析了满布竖向荷载及考虑竖向活载不利布置情况的内力分布差异,以及楼板反弯点的变化规律,给出了楼板负弯矩钢筋截断位置的设计建议。 设计分析模型为一层双向不等柱...To further explore and complete the designing method for RC floor considering beam-slab cooperative work, based on the study of literature [13],[14], [35] ,[36] and [37], the article adjusted, corrected and unified the membrane action coefficient and adjustment coefficient of “3D strip method” which proposed by literature [35] and [36] by nonlinear numerical analysis using FEM (Ansys), and let the...学位:工程硕士院系专业:建筑与土木工程学院_建筑与土木工程学号:2532011115174
