Abstract: An experimental study was performed to investigate the structural behavior of thin-walled rectangular concrete-filled tubular (RCFT) columns。 This study mainly focused on the effects of a high-strength steel slender section on t...
Introduction Hydraulic control technology of mechanical equipment has been widely used in mechanical fault detection and robustness protection and so on [1]。 How to determine the mechanical hydraulic mechanical transmission sys- tem in th...
Robot manipulators require knowledge about their environment in order to perforiii their desired actions。 In several robotic tasks, vision sensors play a critical role by providing the necessary quantity and quality of information regardi...
Rate-based calculations for trayed and packed columns offer process engineers a more rigorous and reliable basis for assessing column performance than the tradi- tional equilibrium-stage approach, especially for multicomponent separations。...
A methodology to deal with the automatic design of internal pins in injection mold CAD via the automatic recognition of undercut features is developed. The approach to automatically identifying the undercut features is first proposed. For t...
摘 要：在级进模上有很多孔用于安装插入、装配和标准件。根据其结构类型及相关零件与板孔之间的关系，给出了级进模设计中孔板的分类，并介绍了级进模自动孔设计系统。利用预建...
Introduction Increasing energy costs and more energy efficient buildings have been driv- ing forces behind the recent emphasis on the construction of tighter building envelopes. Indoor relative humidity has in general increased in these bui...
This invention relates in general to electrical submersible well pump assemblies and in particular to instrument subs that mount to a centrifugal pump. BACKGROUND Electrical submersible pump assemblies are commonly used in hydrocarbon produ...
Wrinkling that occurs in the stamping of tapered square cups and stepped rectangular cups is investigated. A common characteristic of these two types of wrinkling is that the wrinkles are found at the draw wall that is relatively unsup- por...
Abstract Today implant dentistry has made great inroads into the treatment modalities that are available in treating an edentulous patient. Popularity of a two implant retained overdenture has created a necessity to examine the various atta...
