Managing Technological and Financial Uncertainty: A Decision Science Approach for Strategic Drilling Decisions

This paper presents a framework to improve the quality of investment decisions in petroleum. The model presented enables the decision-maker to explicitly consider two major objectives when evaluating new petroleum opportunities—financial and technological gain. We utilize MultiAttribute Utility Theory (MAUT) to consider simultaneously the technological challenges of petroleum exploration into the capital budgeting process of an exploration and production firm. The MAUT methodology presented in this work demonstrates that in some mature areas the advantages to exploration are restricted further only to financial gain, based upon the present economic potential of the basin. On the other hand, other seemingly less attractive areas, such as deep horizons in deep-water basins, may represent attractive targets for new exploration as a result of the interaction of financial gain and technological advancement. This advantage reflects the technological gain as a key factor for future operations for oil discoveries in areas with big geological potential. The model presented in this work enables the decision-maker to consider explicitly the risk and rewards associated with both financial and technological payoffs, the decision-maker's tolerance for those types of risks, and the relative importance of each of those objectives in the context of ongoing petroleum exploration decisions.     

Financial inclusion, universal banking and post offices in Britain

The causes and consequences of financial exclusion have become a policy concern in Britain in recent years. This paper analyses policy discourses around financial exclusion and considers the (social and economic) geographical issues surrounding one particular policy response – universal banking services. It examines the policy background which led to the introduction of these services, and the institutional role of the Post Office, before discussing their potential social and spatial consequences.     

基于局部方差的安全玻璃碎片自动检测算法

针对安全玻璃质量检验中碎片状态试验结果的判定问题,在分析了自然光线下获取的安全玻璃碎片图像特点后,提出了一种安全玻璃碎片自动检测与识别算法。首先,用基于局部方差的直方图均衡化算法进行目标增强;然后,用固定阈值进行图像分割,对缝隙线和碎片内部的噪声分别去除;最后用分水岭变换进行碎片识别。该算法能够准确刻画碎片的缝隙线,得到碎片的块数,并能够为安全玻璃碎片状态试验结果判定提供依据。     

测绘生产成本费用与财政预算科目的比较

介绍了国家测绘局编制的《测绘生产成本费用定额》与湖北省财政厅编制的“财政预算科目”之间的差异。通过两者的比较,阐述了如何使项目预算文本和日常业务处理规范化。这将有益于测绘项目的立项申报及管理。     

医学图像灰度归一化显示技术研究

本文介绍了对肝脏图像进行均衡化处理、维纳滤波处理、中值滤波处理,并按灰度直方图分析的取值对均衡化后灰度图像、维纳滤波处理后的灰度图像、中值滤波处理后的灰度图像进行灰度调整。图像放在一起分析比较图像质量并进行讨论。本论文提出的基于直方图分析的中值滤波灰度调整的图像处理创新技术使肝脏图像处理后图像细腻、组织结构清晰、兴趣区层次感加强,对临床诊断具有积极意义,不通过调节窗宽窗位,达到图像灰度归一化显示,易于计算机自动识别。     

基于DEA-Malmquist-Tobit模型的中国海洋渔业补贴财政效率及影响因素研究

作为世界上最大的渔业生产国和贸易国,中国渔业补贴政策的制定和实施对国计民生具有重大意义,也是推进海洋强国战略建设的题中应有之义。本文选取基于规模报酬可变假设的DEA模型测算了中国海洋渔业补贴的效率水平,进一步利用Malmquist指数对补贴效率的动态变化进行分解,探究效率变化的内在驱动因素,然后建立分析补贴效率影响因素的面板Tobit模型,对补贴投入和环境变量对补贴效率的影响进行分析,结果表明,当前我国海洋渔业补贴效率整体较低,且全要素生产率呈下降趋势,最后基于实证结果从改善补贴规模和调整产业结构等方面提出改善渔业补贴效率的对策建议。
