Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Existence of hyperbolic motions for Newtonian and generalized N-body problem（II）
牛顿 广义N体问题 双曲运动 存在性
2023/11/7
For the classical N-body problem, Maderna-Venturelli [Ann. Math. 2020] proved the existence of hyperbolic motions with any positive energy constant, starting from any configuration and along any nonco...

上海交通大学机械与动力工程学院工业工程与管理系生产计划与控制课件Chapter3.2 A Prototype Problem。
Considerable works were done on physical and geometric use of null curves in the literature ( [2]-[9] ). In this work, we give the analogue of the Frenet -Serret formulas on the lightlike surface and ...
Identification of the solution of the Burgers equation on a finite interval via the solution of an appropriate stochastic control problem
Stochastic Control Theory Lagrangain Brownian motion

A quality problem in seam welds in aluminum extrusion
Metallic alloys Seam weld Aluminum Extrusion Porthole die
2009/12/1
Purpose: Seam welds occur during the hollow profile extrusion; the billet’s material is divided into separate
metal streams by the bridges of the die which support a mandrel, and then these metal str...
