A Two-Step Marginal-Restraint Mandrel-Free Spinning Method for Accuracy in Forming Large, Special-Shaped Aluminum Alloy Tank Domes

open access: yesMetals, 2023
The special-shaped tank dome of a launch vehicle is a large, thin-walled, curved structure that is difficult to form using the conventional center-restraint spinning method.

Process Parameters Optimization of One-Step Spin Forming of Top Cover with Center Flanged Hole

open access: yesMetals, 2023
To assist the low-cost manufacturing of tanks, a one-step method of marginal-restraint mandrel-free spin forming is therefore proposed in this study for the forming of top covers with flanged holes.

The accurate shaping curve for forming inside small right-angle step using cross-wedge rolling

open access: yes工程科学学报, 2022
Cross-wedge rolling (CWR) die generally has three parts: a knifing section, a stretching section, and a finishing section. When forming an inside step, to avoid generating spiral steps, a new transitional section is introduced between the knifing and ...

Completing Disability Forms Efficiently and Accurately: [PDF]

open access: yesPRiMER, 2018
Introduction: The completion of a patient’s disability assessment form (DAF) is a task expected of family and internal medicine physicians. Residency curricula rarely address this task. Thus, some residents are reluctant to conduct functional assessments because of inadequate training, the time required to conduct such an exam, and fear of jeopardizing

A Fast and Accurate Approximation to the Distributions of Quadratic Forms of Gaussian Variables

open access: yesJournal of Computational and Graphical Statistics, 2022
In computational and applied statistics, it is of great interest to get fast and accurate calculation for the distributions of the quadratic forms of Gaussian random variables. This paper presents a novel approximation strategy that contains two developments. First, we propose a faster numerical procedure in computing the moments of the quadratic forms.
