Research and development of intelligent agriculture monitoring system based on Arduino

2050年全球将增加约9.6亿的人口，届时各国的农业部门将面临巨大的粮食缺口。然而可用耕地面积在逐年减少，淡水的需求却在不断增加，还有其他不可预测的因素，例如气候变化的影响等等。面临这些棘手的问题，如何解决庞大人口的吃饭问题，如何解决减少对地球资源的无限制索取，如何提高投入与产出的比，农业的发展就显得非常的重要，纵然有许多方法和策略，但是“智慧农业”是其中必不可少的环节，尽最大可能去提高农产品的质量与数量的方法之一就是“智慧农业”，让农业更智能、更有连接性，让资源消耗最小化、最有效，对它的研究具有巨大的经济效益和社会效益。 论文首先介绍了本研究项目的研究背景和研究意义，然后介绍和引入了开源硬...A large population shall be increased before the year 2050 , and a huge grain gap shall be faced to many country's agricultural sector.

A Study of the Impact of International Vertical Specialization on the Export Sophistication of Chinese Domestic Enterprises

中国对外贸易快速增长的同时，由生产在国际间分工导致的国际垂直专业化贸易也迅速增长，且二者之间有着密切的关系，国际垂直专业化在对外贸易发展过程中扮演了重要角色。另外，在此过程当中，中国出口的产品中也不乏高技术产品，有学者研究发现，中国的出口技术复杂度高于与其经济发展水平相对应的水平，即“Rodrik悖论”。中国凭借低廉的要素成本占据了全球生产网络的低端生产制造与组装环节，并藉此生产和出口了大量的资本技术密集型产品，其中相当一部分是高技术产品。然而，中国目前的这种生产和出口局面并不意味着更多的贸易获利，相反存在着沦为“世界加工厂”并长期受制于发达国家的可能。 本文以中国本土企业为研究对象，借鉴前...China's foreign trade grew rapidly, at the same time, international trade by vertical specialization which was led by international division of production grew rapidly too, and they were closely related, international vertical specialization played an important role in the process of foreign trade development. In addition, China exported lots of high-tech products in the meantime, the export sophi...学位：经济学硕士院系专业：经济学院_国际贸易学学号：1572012115184

Study on Contemporary Design Strategy of the hall of College Architecture Department

随着我国经济地快速发展，建筑行业业已在国民经济中占据越发重要的地位，得到人们普遍的关注。行业的发展需要大量的人才支持，于此相应的是我国建筑教育获得了难得的发展机遇。在承认所取得可喜的成绩同时，我们也需要看到由于行业扩张所带来的诸多问题。而解决这些问题的关键在于学校教育，忽视基本的学校教育将无助于国家建筑行业的规范和良性发展。本文希望通过塑造极具时代特色的建筑系馆来完善学校教育。建筑系馆存在的意义并不仅仅作为专业教学设施，更重要的是在于本身具有极大的教育价值——在潜移默化中塑造学生的建筑观，而如何发掘这些潜在的资源则在于建筑系馆是否能正确体现时代潮流的发展方向。 本文主体分为两个部分：上部分主...With the rapid development of China's economy, the construction industry has been increasingly important in the national economy , which has gained the widespread attention. Development of the industry requires a lot of talent supporting, which provide China’s architectural education a rare opportunity for development.

Biosorption and Bioreduction of Silver by Bacterium SH09 and their Characterization

微生物对于金属离子的生物吸附和生物还原作用因其在环境保护和金属回收方面的潜在应用价值而一直受到人们的关注。本文主要研究了细菌SH09对一价银离子和银氨离子的吸附还原特性，并基于这一过程的生物还原机理制备出了纳米级的单质银颗粒。SH09菌种是从福建上杭金属矿区废水排出口附近的土壤分离得到的一株微生物，初步鉴定其属于棒状杆菌。以SH09的干菌体和活菌体为研究对象，本文探讨了二者在不同条件下对一价银离子Ag+和银氨离子[Ag(NH3)2]+的吸附特性。结果表明，吸附液pH＝2和5的条件下，SH09干菌体对Ag+的吸附是一个快速的过程，其最大吸附量分别约为260和230mg(Ag)/g(干菌体)。当p...Biosorption and bioreduction of metal by microorganisms has received much attention due to its potential applications in the field of environment protection and metal recovery.

气候变化对中国海洋经济可持续发展的影响

为评估气候变化及实施减排政策对中国海洋经济的影响,本文构建了中国海洋经济社会经济核算矩阵(marine social accounting matrix,MSAM),并以此为数据基础构建中国海洋经济可计算一般均衡(computable general equilibrium,CGE)模型,并将该模型与气候变化影响模型相结合,从而实现了从气候变化对自然系统的影响到对经济系统影响的转化。论文设计了实施和不实施温室气体减排两种政策时的可能的6种气候变化情景。各情景的模拟分析表明:海平面上升同时考虑天文潮最高潮位、同时考虑最大台风暴潮和最大天文潮耦合影响两种子情景下,中国实施减排政策对沿海GDP的影响要分别比不实施减排政策低0.19%和0.12%;海平面上升叠加天文潮、风暴潮3种子情景下,实施减排政策对海洋经济的影响要分别比不实施减排政策低1.67%、0.72%、0.37%

Design of tracking system for marine moving object

为实现对海上运动目标的实时跟踪,克服跟踪效果易受到严重遮挡影响的缺点,建立了一套实时跟踪系统,并且结合目标的运动信息与新的模型更新策略,对均值漂移与卡尔曼滤波器相结合的跟踪算法做出了改进。当运动船只被遮挡的比例较大时,先用估计出的目标速度矢量更新卡尔曼滤波器,并用相应的模型更新策略更新目标模型以提高模型相似性度量的精确性,再单独利用滤波器进行跟踪,取得了较好的跟踪效果。实验结果表明,该系统可以较好地实现海上运动目标的跟踪,并且改进后的算法具有良好的实时性和鲁棒性。To accomplish the real-time tracking for the marine moving object and overcome the defect of the susceptibility to severe occlusion,a set of real-time tracking system for the moving object at sea is designed.In virtue of the motion information and a new kind of model update strategy,some improvements are made for tracking algorithm combining the mean-shift with Kalman filter.When the moving vessel is largely blocked,Kalman filter is updated by the prior estimated velocity vector,and the accuracy of model similarity measurement is improved by utilizing the model update strategy,then the filter is exploited to implement tracking.The algorithm achieved good tracking effect.Experimental results show that the system implement marine moving object tracking with good real-time performance and robustness
