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.

Business Plan of All Optical Fiber BCG Health Monitoring System [PDF]
本人选择非接触式的健康监测作为毕业后的创业项目,是因为该项目符合当今时代的潮流,具有广阔的市场前景。中国正进入深度老年化的社会,加上人们生活水平的不断提高,这些因素都使得大家都日益关注健康。 健康离不开日常监测这个重要手段。目前在健康监测这个领域,轻便的可穿戴设备正逐步取代笨重的传统设备。可穿戴设备是必须穿戴才能检测,这是它的不足之处,这就给非接触式的健康监测留下了一个利基市场。那怎样站到这个风口上,让自己飞起来呢?古语云“千里之行,始于足下”,首先要找到一个合适的切入点进入市场。 本文结合管理学的理论,

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