Elliptic Curve Cryptography
Elliptic curve cryptography (ECC) is a modern form of public-key cryptography based on the algebraic structure of elliptic curves over finite fields. It emerged in the late 1980s and has risen to prominence as a viable alternative to other public-key cryptographic algo......
Optimization of Model Parameters in Stainless Steel Rolling
Optimization of Model Parameters in Stainless Steel Rolling
Stainless steel rolling is a process in which stainless steel is formed and shaped into various shapes through the application of rolling force. It is widely used in industrial applications such as forming large steel parts and component......
Cr12 (D3) (annealing, quenching and tempering) metallographic diagram
Cr12(D3) is a heat-resistant ferritic stainless steel whose main alloying elements are chromium, tungsten and vanadium. It is widely used in the oil, chemical and mining industries for its high temperature and corrosion resistance. Apart from its excellent properties, Cr12(D3) can also be heat tre......
