欠驱动多指机械手优化设计与抓取稳定性分析

针对欠驱动机械手多模式抓取问题，提出了一种手指可拆卸、具有复合抓取功能的欠驱动机械手。为了研究欠驱动手的抓取性能，分别研制了一种弹簧自适应3指节手指机构和一种双四连杆3指节手指机构，两种手指机构均使用四连杆机构的运动原理。手指的性质对欠驱动机械手的抓取稳定性影响很大，对欠驱动机械手单个手指的属性进行分析，分析了关节接触点位置及接触力对抓取稳定性的影响，提出了接触力及力矩平衡的研究分析方法，探讨了影响抓取稳定性的因素

操作式条件反射自动监测系统

&lt;正&gt; 操作式条件反射是在条件信号呈现后,通过有机体自身的某个特定的操作行为而获取食物或回避有害刺激的反射活动。由于操作式条件反射需要动物自身去寻找出一个适当的反应,因此,这种反应便具有一定的主动性。 半个世纪以来,传统的斯金纳箱在动物的简单的联想学习或条件作用的研究中曾起过积极作用。并且,直到今天,它在神经科学的各个领域,特别是在生理心理学、动物行为学和神经药理学等学科的研究中继续发挥其应有的作用。但是,传统的斯金纳箱在每次</p

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel

JUNO sensitivity on proton decay p → ν K + searches*

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the $p\to \bar{\nu} K^+$ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar{\nu} K^+$ is 36.9% ± 4.9% with a background level of $0.2\pm 0.05({\rm syst})\pm$$0.2({\rm stat})$ events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is $9.6 \times 10^{33}$ years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
