Cyclic olefin copolymer (COC) is an amorphous polymer made by several polymer manufacturers. COC is a relatively new class of polymers as compared to commodities such as polypropylene and polyethylene. This newer material is used in a wide variety of applications including packaging films, lenses, vials, displays, and medical devices.

El COEC és una corporació de dret públic que agrupa els odontostomatòlegs de tot el territori català, amb la finalitat d’ordenar el desenvolupament de la seva activitat professional en tots els seus àmbits.

2019年4月8日 · The normalization method has been employed to estimate the J–resistance ( $$J{-}R$$ ) curves for C-shaped outside edge-notched compression (COEC) specimens of SA-508 steel. The COEC specimens present the lowest $$J{-}R$$ curves in comparison with other three types of specimens.

Polypropylene fabric sofa material is a synthetic thermoplastic polymer made from crude oil and natural gas. Also called olefin, it’s an affordable choice for indoor and outdoor sofas. Olefin sofa material has these advantages: stain-resistant and colorfast; cleans easily; breathable; soft and smooth; weather-resistant for outdoor use; durable

采用含外侧边裂纹C形压缩 (C-shaped outside edge-notched compression,COEC)小试样,基于量纲一载荷分离理论发展了其用于获取延性材料的断裂韧度的规则化测试方法。 采用A508-III压力容器钢完成了不同规格COEC、紧凑拉伸 (Compact tension,CT)和单边裂纹弯曲 (Single edged-notched bending,SEB)试样的J阻力曲线试验。 结果表明,相比试样厚度,初始裂纹长度对COEC试样的J阻力曲线测试结果影响更大。 同时,由于COEC试样具有更高的裂尖约束水平,其J阻力曲线明显低 …

2024年8月8日 · Within the CoECs population, we identified (1) CoEC I, a microvascular subtype displaying a capillary-to-venous transcriptional profile, (2) CoEC II, a microvascular subtype with a capillary-to-artery profile; (3) CoEC III, representing arterial cells; and (4) CoEC IV, representing large caliber arterial cells, likely including the pulmonary ...

在材料断裂行为评定中,试样小型化不仅具有取样方便和节约成本的优点,而且对满足特殊取样要求的断裂韧度测试有重要工程意义.采用含外侧边裂纹C形压缩(C-shaped outside edge-notched compression,COEC)小试样,基于量纲一载荷分离理论发展了其用于获取延性材料的断裂 ...

coec即click over expected click，可以用来处理某些bias问题,比如最简单的位置偏置。 以解决位置偏置的coec为例，假设计算广告商家的coec，先统计每个位置上的点击率，然后广告商家在每个位置上的曝光乘以各个位置上的点击率，得到广告商家的期望点击数，最后 ...
