The posts presents my reflection about aspects of CAM, error compensation and materials. The example of submarine propellers is quite reasonable in it and facilitates following of article. Submarines are one of the most important weapon and therefore it’s worth reading about them. Some recent submarine disasters have been mentioned to show that we still have to develop our CAM tools and materials in order to produce better products.
The post presents selected applications of Fourier Transform with a short description. Telecommunication, automotive industry, medical industry, general IT, physical, geological, mechanical and military applications have been explained. The Powerpoint slides from the talk about guide on FFT numerical methods I gave at my university is available for download.
