2020年8月12日 · Normal mode expansion (NME) of hollow cylinder guided wave modes for a radial point source excitation is derived analytically. Mutually orthogonal guided wave modes in the hollow cylinder are used for NME, and the modal participation factors are …

In this paper, the excitation and propagation of guided waves in multilayer hollow cylinders with piezoelectric wafer active sensor (PWAS) transducers were modeled with the normal mode expansion (NME) method using the semi-analytical finite element (SAFE) formulation.

2019年8月15日 · Guided wave modeling for multilayer geometries by using SAFE is not an appropriate methodology for normal mode expansion (NME) solution even though SAFE has many advantages. This paper proposes to integrate the SAFE and GMM to achieve accurate stress mode shape prediction as needed in NME solution.

2020年5月7日 · This paper presents the excitation and propagation of guided waves in arbitrary cross-section structures by coupling the normal mode expansion (NME) method with the semi-analytical finite element (SAFE) method. Then, a Tee-bar example of finite element (FE) simulations is performed to validate the proposed SAFE-NME method.

2023年8月24日 · 基于半解析有限元（safe）方法，开发了一种在具有各向同性和各向异性材料特性的声弹性和复杂波导中传播的引力波的开源色散计算器。 首先，通过假设沿传播方向的简谐振动并沿厚度方向离散化，采用1D-GLL-SAFE（一维Gauss-Lobatto-Legendre SAFE）来求解板波导 …

国FDA的两种特殊分类， 新分子实体 （NME）和 新化学实体 （NCE），之间的差异可能有些让人摸不着头脑。 NME是指 其活性成分不含有先前经FDA批准的活性部分的药物。 NCE是指 不含先前由FDA批准的有效部分的药物。 这两种分类几乎逐字相似，甚至接触初期它们可能看起来是重复的。 但这两者并不是完全相同，而是遵循了西方世界一句古老的格言—— 每个正方形都是矩形，但并不是每个矩形都是正方形。 根据笔者查询的资料，NCE和NME，区别就在于NDE强调的是 …

Neuromuscular and Muscular Electrical Stimulation (NMES) is a modality that sends electrical impulses to nerves which causes the muscles to contract mimicking the action potential coming from the central nervous system. It may be applied during functional movement or without functional movement.

NME是英国的一个有着悠久历史的乐评杂志和网站。 （1952年成立） 同样，NME也是十分常见，你也可以在很多实体专辑封面看到他们的评价。 （英媒代表？ 也是老牌乐评了。 我比较常看的是pitchfork的评分，还有noisey的文章。 pitchfork网站的ui比其他的好太多了…
