Obtaining Forming Limit Diagram Using OpenCV [PDF]
한국정밀공학회지The Forming Limit Diagram (FLD) is a criterion used to assess the formability of sheet metal during a manufacturing process. Traditionally, FLDs are obtained through manual measurements using Mylar tape or through the use of automatic deformation ...

Single-Point Incremental Micro-Forming of Thin Shell Products Utilizing High Formability
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010 This paper describes single-point incremental micro-forming of miniature shell products 50 µm to 1000 µm in size. First, the conditions of the micro-forming of a pyramid with a 1 mm square base were optimized to cause large elongation of a ...

Cusp forms as p-adic limits [PDF]
Journal of Number Theory, 2022 Ahlgren and Samart relate three cusp forms with complex multiplication to certain weakly holomorphic modular forms using $p$-adic bounds related to their Fourier coefficients. In these three examples, their result strengthens a theorem of Guerzhoy, Kent, and Ono which pairs certain CM forms with weakly holomorphic modular forms via $p$-adic limits ...
