Multiple positive solutions to third-order three-point singular semipositone boundary value problem

By using a specially constructed cone and the fixed point index theory, this paper investigates the existence of multiple positive solutions for the third-order three-point singular semipositone BVP: \begin{cases} x'''(t)-\ld f(t,x) =0, &t\in(0,1); [.3pc] x(0)=x'(\eta)=x''(1)=0, & \end{cases} where ${1/2}<\eta<1$, the non-linear term f(t,x):(0,1)\times(0,+\i)\to (-\i,+\i) is continuous and may be singular at $t=0$, $t=1$, and $x=0$, also may be negative for some values of $t$ and $x$, \ld is a positive parameter.Comment: 14 page

Exploration on new ideas of robot teaching reform in Colleges and universities

with the proposal of intelligent manufacturing 2025 action program, it points out the development direction for the transformation and upgrading of China’s manufacturing industry, and also gives suffi cient power to relevant industries. The research on the cultivation of innovative engineering science and technology talents in the Chinese Academy of engineering has shown that China’s future modernization and economic development need scientifi c and technological talents with diversifi ed attributes, which also puts forward new requirements for robot teaching and talent cultivation in relevant colleges and universities. In view of this, in the process of robot teaching, it is necessary for university teachers to innovate their teaching ideas, improve the quality of professional teaching, break through the shackles of traditional teaching, build an effi cient talent training system through the integration of modern teaching ideas, complete the reform and innovation of robot teaching, and cultivate more talents with social developmentPractical professional talents suitable for the development of the industry. Based on this, this paper analyzes the current situation of robot teaching in Colleges and universities, and puts forward some ideas and suggestions for the teaching reform, in order to add fuel and raise wages for the teaching reform of robot in Colleges and universities

Integrated design and Research on driving and controlling structure of robot intelligent joint

at present, the robot industry is widely concerned in China, and there are more robot production and R & D enterprises. However, robots are subject to many restrictions in the application process, including industry development, enterprise structure, robot R & D and robot manufacturing. Many small enterprises have a series of characteristics such as low production and short cycle, so it is necessary to continuously optimize and update the robot to meet the needs of enterprises. The emergence of integrated design of drive control structure can eff ectively solve these problems. In the current development process, there is a high demand for the personalization and intelligence of robots. Therefore, this paper designs and studies the drive control structure integration of robot intelligent joint, in order to promote the development of robot industry
