Keywords: BP neural network, fuzzy control, cutting platform height, multisensor ABSTRACT In this paper, BP neural network is used to collect header height, AMEsim is used to simulate and analyze header height adjustment hydraulic system, and fuzzy PID control is used to adjust header lifting hydraulic cylinder to stabilize header height. The experimental results of harvesting different crops show that under the header height automatic control system, the error between the actual height of crop harvesting and the set height is within 15 mm, and the harvesting effect is good, which can meet the automatic regulation requirements of the header height of the multi crop combine harvester. 摘要 为了提高调节的精度,采用 BP 神经网络多传感器融合处理技术采集割台实时高度,通过 AMEsim 软件对割台 高度调节液压系统进行仿真分析,最后采用模糊 PID 控制比例电磁阀调节割台升降液压缸从而稳定割台高度。 通过收获油菜、谷子和水稻的试验结果证明:在割台高度自动控制系统下,作物收获的实际高度与设定高度误
This article discusses the grand strategy imperatives of 37 foreign policy experts in Washington, DC. in response to President Donald Trump's nationalist challenge to the post-WWII international order concept. Using an abductive reconstructivist methodology to analyze in-depth interviews, five grand strategy imperatives or rules for action shared by all actors were identified: safeguarding US global leadership, maintaining alliances, securing US prosperity, value orientation, and the belief in a mission. Based on the interpretation of these rules for action, four types of foreign policy experts were distinguished: nationalists, realists, pragmatic liberals, and liberals. The latter three expert types, also labelled globalists, were united in their opposition to the nationalists' demolition of the international order but divided along partisan and ideological lines about the meaning and implementation of the rules for action. Realists, pragmatic liberals, and liberals were also unsure of how to explain and respond to Trump's nationalism beyond a defensive or wishful hope to save the vestiges of an US-centric international order. The findings demonstrate the value of in-depth qualitative interviews for explaining elite beliefs, illustrating the rich insights for policy analysis that can be gained through this methodology.
在整个欧洲的古代社会中,仍然缺乏对火山主义对气候和人民的直接影响的明确了解。In our study, we analyze an extensive set of radiocarbon dates from excavated archeological sites from several regions of Scandinavia, providing detailed information on societal changes, and combine this with paleocli- mate simulations performed with a high-resolution (0.25° or ~25 km) climate model to examine the impact of volcanism on Scandinavia in the 6th century AD.尽管已经广泛研究了气候与火山之间的联系(例如Goosse and Renssen,2004年;琼斯等人,2005年; McGregor和Timmermann,2011年; Robock,2000年; Schmidt等,2004; Schneider等,2009; Timmreck等人,2010年),这些研究尚未从经验上探索社会影响(Iversen,2016; Pfister,2010; Solheim and Iversen,2019)。我们的研究追踪了536/540 AD火山喷发的气候影响以及人类对其对其的反应,使用14 C考古记录和降低气候模型的比较分析。我们的分析比较了瑞典与北部沿海地区和内陆地区之间的反应,重点是土地使用的时空变化。结合气候和考古数据
