基于生命周期评估方法的不同材料建筑物环境影响分析

基于生命周期评估方法（ Life Cycle Assessment ）,本文对一教学楼以“相同的建筑平面与面积、相同的服务功能、满足基本安全与经济目标”原则,分别采用木结构、混凝土结构和钢结构进行设计。根据建筑设计方案,采用Athena Eco-calculator清单模型计算三种建筑物在不考虑使用阶段运行能耗的生命周期内对环境的影响指标,包括能源消耗、原材料使用量、温室效应、酸雨、对人类呼吸健康的影响、水污染、臭氧损耗、光化学烟雾效应等,得出：木结构作为天然有机材料,建筑能耗、对人类健康的影响和生态破坏均比混凝土结构和钢结构低,体现了环境友好性。     

Risk reduction in Sechahun iron ore deposit by geological boundary modification using multiple indicator Kriging

Uncertainty on the geological contacts and the block volumes of the models along boundaries is often a major part of the global uncertainty of reserve estimation.This work introduces a geostatistical technique that has been developed and tested in an iron ore deposit at Bafq mining district,in central Iran,and that,based on a probability criterion,helps to objectively model the geometry of this iron ore deposit.The main problem in reserve estimation of this ore body is its geometrical modeling and uncertainty in geological boundaries.This work deals with the geostatistical method of multiple indicator kriging,which is used to determine the real boundaries of ore body in different categories.This approach has potential to improve project performance and decrease operational risk.For this purpose,the ore body is separated into two categories including rich iron zone （w（Fe）〉45%） and poor iron zone （20%〈w（Fe）〈45%）.It significantly benefits to decrease the risk of reserve evaluation in the deposit.This case study also highlights the value of multiple indicator kriging as a tool for estimates the position of grade boundaries within the deposit.Comparison of the resultant probability maps with the real ore/waste contacts on the extracted levels shows that the first indicator model could separate the whole ore body （poor plus rich） from the waste zone by probability of more than 0.35,which concludes the total reserve of 53 million tons.The second indicator model applied to separate the rich and poor domains and the results show that the blocks with the estimated probability of equal to or more than 0.4 lay within the rich ore zone consisting of 15.8 million tons reserve.     

Areas vulnerable to natural disasters and damage estimation of infrastructure in Busan,Korea

Since the damages caused by disasters associated with climate anomalies and the diversification of the social structure increase every year, an efficient management system associated with a damage assessment of the areas vulnerable to disasters is demanded to prevent or mitigate the damages to infrastructure. The areas vulnerable to disasters in Busan, located at southeastern part of Korea, were estimated based on historical records of damages and a risk assessment of the infrastructure was performed to provide fundamental information prior to the establishment of the real-time monitoring system for infrastructure and establish disaster management system. The results are illustrated by using geographical information system（GIS） and provide the importance of the roadmap for comprehensive and specific strategy to manage natural disasters.

以教学实习为资源的英语专业毕业论文写作指导

对英语专业毕业论文写作中存在的问题已有不少研究,但对论文写作主体对相关课题的体验认知基础在论文写作中的作用尚未给予足够的关照。通过对英语教学型论文写作过程的调查分析,论证学生缺乏教学实践及科研过程的体验和认知是导致论文写作中主要困难的诱因;在此基础上,根据认知主义理论的写作观,尝试探索以学生自身实习为资源的毕业论文写作指导模式及论文评价体系的建构。     

农村公路典型路段事故风险评价方法

农村公路急弯、陡坡、路侧险要等典型路段往往是事故易发多发路段。在现阶段农村公路安保工程资金有限的情况下,需对既有典型路段的事故风险进行定量评价和排序,为隐患路段的排查和安保工程分期实施提供依据。在现有研究成果的基础上,构建典型路段事故风险评价指标体系,提出一种基于贝叶斯网络的农村公路典型路段事故风险评价方法。该方法能有效集结专家知识和经验定量评价典型路段(包括单一路段和组合路段)的事故风险,并可以随着数据的更新不断完善模型。在农村公路事故资料相对缺乏的情况下,该方法具有较强的实用性。     

基于Contourlet域梯度结构相似度的无参考图像质量评价

Contourlet变换已经成为多尺度、多方向图像处理领域的研究热点,文章将其引入图像质量评价,提出了一种基于Contourlet变换的梯度结构相似度无参考图像质量评价方法（NRCT-GSSIM）,将待评价图像通过高斯低通滤波器构造参考图像,然后在Contourlet变换域中计算图像频率子带、方向子带分别加权的梯度结构相似度,实现对图像的质量评价.该方法无需标准参考图像,充分考虑了人类视觉特性.实验结果表明,NRCT-GSSIM取得了与峰值信噪比（PNSR）、结构相似度（SSIM）和梯度结构相似度（GSSIM）等有参考图像质量评价相一致的评价结果,且较之PSNR、SSIM有更高的准确性.
