Process Parameters Optimization of One-Step Spin Forming of Top Cover with Center Flanged Hole
Metals, 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
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]
PRiMER, 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

Semigeostrophic Particle Motion and Exponentially Accurate Normal forms [PDF]
Multiscale Modeling & Simulation, 2006 We give an exponentially accurate normal form for a Lagrangian particle moving in a rotating shallow-water system in the semigeostrophic limit, which describes the motion in the region of an exponentially accurate slow manifold (a region of phase space for which dynamics on the fast scale are exponentially small in the Rossby number).
