The lifetime of a micro proton exchange membrane fuel cell is hugely dependent on the durability and longevity of the membrane used in the cell. An ideal membrane is expected to have its membrane impedance constant and distributed uniformly throughout. But in practice, the case is quite different. Such non uniformities in the membrane impedance will generate local hotspots in the membrane which has...
Random number generators are a vital component in many cryptographic algorithms and systems, such as generation of keys in secret key cryptography and public key cryptography. For cryptographic applications, True Random Number Generator utilizes unpredictability as the key component. Insufficient entropy produces predictable keys, so the major concern is to have a better entropy source. Entropy source...
