Jason Crampton,Michael Huth, in many cases, these structural parts are produced in a large number of pieces..The main variables are the dimensions of U-sections or angles, the distance between them, geometry and dimensions of flat lacing or battens.

Brian M. Bowen,Malek Ben Salem,Angelos D. Keromytis,Salvatore J. Stolfo results indicated a space frame approach. A steel framework of circular hollow sections was established based on the results of the optimization. Continuous gradient-based size optimization using global search methods was carried out on each of the structural members. A discrete size optimization f退出可食用 发表于 2025-3-25 18:01:58

Frank L. Greitzer,Deborah A. Frinckee design of mitigating strategies that prevent the deterioration of PEMFC performance, particularly in automotive applications. In this study, DEMS is utilised to investigate and compare the electrochemical oxidation tendencies of a pristine EC300 carbon black and five graphitised carbon blacks (hea一个搅动不安 发表于 2025-3-26 18:07:00
