This paper investigates a time-inconsistent stochastic linear-quadratic problem with regime switching that is characterized via a finite-state Markov chain.Open
Random variables and uncertain variables are respectively used to model randomness and uncertainty.While randomness and uncertainty always coexist in a same com
In this paper,linear quadratic(LQ)optimal control problems are investigated for two types of uncertain random systems which consider the coefficient of the pert
“云求职”作为以网络招聘平台为载体的就业渠道,在疫情防控背景下备受关注,但现有研究却鲜有考察其对就业质量的影响.以疫情防控时期高校毕业生普遍采用的“云求职”方式为切入点,对500名2021届高校毕业生进行问卷调查与回归分析发现:毕业生就业竞争力、求职渠道差异会影响毕业生的工作满意度;家庭相对收入、学习成绩、“云求职”渠道是高质量就业的独立影响因素,且家庭相对收入情况起负向预测作用,大学期间学习成绩和“云求职”渠道起正向预测作用.
根据智能电网用电配电实际,结合物联网技术,对高稳定电能计量终端软件进行了研发,电力测量监视系统考虑了本地计算机系统操作过程中将会出现的最坏情况,在运行过程中,如果有掉电等相关问题出现时,系统将发挥出重要功能,自动计算采集数据中断点.为了与电力物联网架构平台层相适应,使软件检索功能更加快捷方便并完成电量数据存储再进行集中统计分析等操作,为了实现以上功能,必须要对数据库进行设计和移植MQTT代理服务器
This paper investigates sampling dependent stability for aperiodic sampled-data systems by employing a Lyapunov-like functional that is time-dependent,and not i
为建立“阳光玫瑰”葡萄嫩茎组织培养体系,以其嫩茎作为外植体,进行灭菌时间的确定,初代培养基、继代培养基、生根培养基的筛选及抗褐化培养,以期为后续进行种苗脱毒及生产种植提供技术基础.结果表明:嫩茎用0.1%HgCl2灭菌9 min为最佳处理时间,萌芽率达到最大,外植体无污染无死亡;MS+1.0 mg/L KT+0.1 mg/L NAA是嫩芽茎段芽分化最适宜的培养基,萌芽率达93.3%,平均诱导2个芽;通过添加PVP有良好的抗褐化效果,以2.0 mg/L浓度为适宜;继代培养则筛选出MS+1.5 mg/L KT
