Data Fusion Based KF-UI with Real Time Estimation of Dynamic Displacement and Decentralized Control [PDF]

open access: yes, 2017
结构健康监测与振动控制在结构安全及可靠度评估方面起着重要的作用。结构动荷载是结构设计和结构健康监测的重要基础。然而,在实际工程结构中,直接通过传感器测量结构的动荷载是非常困难的,尤其是风荷载等分布荷载的测量。因此,研究通过测量结构响应获取结构动荷载受到广大科研工作者的重视,并取得了可观的研究成果,但是现有的研究仍然存在一定的局限性。 另外,在未知激励的条件下进行系统识别(包括结构动位移识别)研究也具有非常重要的意义。结构动位移是描述结构振动特性非常必要的物理参数,许多理论方法都是先获得结构位移 ...

Pollinator diversity, pollination services, and conservation in agroecosystems: A mini‐review on the successes and challenges in China

open access: yesIntegrative Conservation, Volume 3, Issue 2, Page 104-111, June 2024.
While many pollinator studies have been conducted in China, more efforts are required to conservation pollinators and pollination services. Three proposed conservation interventions were proposed in this mini‐review, including long‐term pollinator monitoring plan, design suitable agricultural landscapes, and wildflower strips and bee hotels.

肝细胞癌患者血浆循环DNA的定量分析及临床意义

open access: yesZhongguo shiyan zhenduanxue, 2015
目的定量检测肝细胞癌(HCC)患者血浆循环DNA(cf-DNA)含量,探讨其在原发性肝癌早期诊断及病情监测中的临床应用价值。方法收集40例肝细胞癌、30例代偿期肝硬化、20例活动性肝炎和25例正常健康对照血浆,提取血浆循环DNA,采用real-time实时荧光定量PCR方法检测β-actin基因的表达,确定血浆循环DNA的水平。结果20HCC组、肝硬化组、肝炎组和健康对照组中位血浆循环DNA浓度分别为17.090ng/ml、8.182ng/ml、7.447ng/ml和9.014ng/ml ...

Real-time identification of time-varying structures and integration with vibration control based on extended Kalman Filter with unknown inputs [PDF]

open access: yes, 2017
建筑结构的参数识别与损伤诊断是结构健康监测领域中的一项重要课题。在过去的数十年内,业内许多专家与学者给出了理论各异的,基于结构振动响应的参数识别与损伤诊断方法。然而,这其中的许多方法,大都是针对于时不变系统的。但在重大荷载发生时(如高烈度地震等),结构单元发生损伤,它的物理参数(如刚度等)在荷载作用中是随时间变化的。为了实时地捕捉这一变化,结构健康监测系统应该具备在线地识别时变结构参数的能力。 因此本论文在第二章,在前人基础上得到了基于改进的自适应卡尔曼滤波的时变系统在线识别方法。与现有文献相比 ...

Design and Implementation of Bridge Management System Based on PDA [PDF]

open access: yes, 2015
随着我国城市基础建设的快速发展,新增许多大型桥梁建筑。因此对于桥梁的质量安全,被各级相关部门所关注。因此桥梁管理系统得到了一定的发展。桥梁质量检测管理工作是保证桥梁质量安全的重要环节,但是现在常用的桥梁管理系统中大多抓不住对桥梁检测的支持,桥梁检测数据的采集是现在桥梁管理中的一个重要问题。 本文采用的PDA移动数据采集技术,研究开发了“基于PDA外业数据采集的桥梁管理系统”,实现了桥检数据采集、录入和处理的有机集成。 这套管理系统主要用于桥梁质量检查,用户定位桥梁检测的相关单位和对桥梁进行养护的相关单位。
