The applications of intelligent techniques have increased exponentially in recent days to study most of the non-linear parameters. In particular, the behavior of earth resembles the non- linearity applications. An efficient tool is needed for the interpretation of geophysical parameters to study the subsurface of the earth. Artificial Neural Networks （ANN） perform certain tasks if the structure of the network is modified accordingly for the purpose it has been used. The three most robust networks were taken and comparatively analyzed for their performance to choose the appropriate network. The single- layer feed-forward neural network with the back propagation algorithm is chosen as one of the well- suited networks after comparing the results. Initially, certain synthetic data sets of all three-layer curves have been taken tk^r training the network, and the network is validated by the field datasets collected from Tuticorin Coastal Region （78°7＇30＂E and 8°48＇45＂N）, Tamil Nadu, India. The interpretation has been done successfully using the corresponding learning algorithm in the present study. With proper training of back propagation networks, it tends to give the resistivity and thickness of the subsurface layer model of the field resistivity data concerning the synthetic data trained earlier in the appropriate network. The network is trained with more Vertical Electrical Sounding （VES） data, and this trained network is demon- strated by the field data. Groundwater table depth also has been modeled.

尾矿库溃坝灾害应急响应时间短、潜在威胁巨大,往往造成惨重人员伤亡与巨额财产损失.近些年尾矿库安全事故发生数量的总体下降趋势充分体现出现代化技术及安全管理方面的进步,然而重大事故发生频次却不减反增,2015年巴西Samarco铁矿与2014年加拿大Mount Polley重大溃坝事故及其惨重后果,再次为尾矿库安全敲响警钟.我国现存尾矿库8869座,含＂头顶库＂1425座,安全形势复杂.本文在收集大量相关领域文献的基础上,聚焦尾矿库溃坝灾害防控体系中的安全监测、灾害预警与应急准备、安全管理与标准规范这三大方面核心内容,分别综述对比国内外现状及前沿进展,探讨分析我国当前所面临的问题并尝试提出改进建议,为尾矿库防灾减灾理论研究与技术革新提供参考.结果表明：（1）我国尾矿库安全监测标准更高,但仪器耐久性、可靠度与实用性不足,专用监测器件与新技术的研发应用势在必行;（2）灾害预警方法单一且可信度不高,而信息技术融合应用成为发展趋势;（3）应急管理与预警决策需以充分的科学论证为基础,当前研究在试验手段与计算方法上存在局限;（4）我国拥有完善的安全管理标准规范体系,但在安全等别划分、全生命周期管理、主体变更、事故总结等方面相对欠缺.

Nursing student engagement is a critical and enhancing means of ensuring students stay within their education, and subsequently within the nursing profession. Engaged students with having higher ethical standards and behaviors, are certainly “caring” with their care delivery, and are dependable and competent with their teamwork. These are rewarding aspects of nursing practice. This research evaluates student nurses’ perceptions and their sense of engagement in relation to nursing and their educational experiences.

研究目标:引入一种基于年度全局Moran指数比的内生时空权重矩阵构建方法,并评估其合理性。研究方法:基于标准化的空间权重矩阵和以年度全局Moran指数比为基础的时间权重矩阵,经过克罗内克积组合形成内生时空权重矩阵;并以两江新区辐射带动力影响因素分解问题为例,评估了内生时空权重矩阵的引入合理性。研究发现:相对于传统的外生时空权重矩阵而言,内生时空权重矩阵能够模拟空间溢出效应在时间上的动态转移和传导效应,却不会导致模型估计结果变异性质发生明显改变。研究创新:构建了一种新的内生性的、包含可变时间效应的时空权重矩阵。研究价值:为面板数据空间计量模型建模实践构建了一种更为精准的时空权重矩阵设计方式。
