Analysis of multisource errors accompanying process execution and study the propagation effects corresponding multiprocess manufacturing are basic prerequisites for optimizing generation improving quality product. This paper proposes an analytical framework error in manufacturing, which completely covers source analysis, mathematical calculation accumulation, description effects, can provide be...
shape error due to elastic recovery of formed part in unloading known as springback, is one of the most important problems of tool design in sheet metal forming processes. many researches have been performed for proposing an efficient method to decrease or compensate springback error in sheet forming processes. these methods are usually based on iterative finite element algorithms. in this pape...
BACKGROUND Testosterone measurements that are accurate, reliable, and comparable across methodologies are crucial to improving public health. Current US Food and Drug Administration-cleared testosterone assays have important limitations. We sought to develop assay performance requirements on the basis of biological variation that allow physiologic changes to be distinguished from assay analytic...
