An analytical expression has been obtained for a surface transfer function which relates the surface micro-roughness to the scattered distribution o... | <urn:uuid:bfbc8e25-04bb-40e5-bee1-ecb8d304122a> | 2.546875 | 252 | Academic Writing | Science & Tech. | 34.372348 | 95,625,017 |
The Mathematical Analysis of Electromagnetic Fields around Surface Cracks in Metals
The work described in this paper arises from a program for the detection and measurement of surface cracks in metals carried out at University College London. The instrument which was developed for the purpose, the Crack Microgauge, emp... | <urn:uuid:72c4e707-f0a6-4ce5-b51c-81791f99f3d7> | 2.578125 | 855 | Academic Writing | Science & Tech. | 65.56929 | 95,625,049 |
