Numerical Simulation of Random Irregular Waves for Wave Generation in Laboratory Flumes
Understanding of wave hydrodynamics and its effects are important for engineers and scientists. Important insights may be gained from laboratory studies. Often the waves are simulated in laboratory flumes do not have the full characteristics of real sea waves. It is then necessary to present reliable methods of wave generation in wave flumes. In this paper, the results of numerically simulate...
متن کاملRandom generation of coherent solitary waves from incoherent waves.
The random generation of coherent solitary waves from incoherent waves in a medium with an instantaneous nonlinearity has been observed. One excites a propagating incoherent spin wave packet in a magnetic film strip and observes the random appearance of solitary wave pulses. These pulses are as coherent as traditional solitary waves, but with random timing and a random peak amplitude.
متن کاملRandom number generation by chaotic double scroll oscillator on chip
Generation of good non-repeatable and non-predictable random number sequences is of increasing importance, both in security applications and in simulations. A novel, compact system is presented in which a secure random number is generated by sampling a chaotic system and using this bitstream as the input to a pseudo-random generator. An optional hash function can be used on the seed in order to...
متن کاملPhysical random bit generation from chaotic solitary laser diode.
We demonstrate the physical generation of random bits at high bit rates (> 100 Gb/s) using optical chaos from a solitary laser diode and therefore without the complex addition of either external optical feedback or injection. This striking result is obtained despite the low dimension and relatively small bandwidth of the laser chaos, i.e. two characteristics that have been so far considered as ...
متن کاملTrue Random-Bit Generation Using a Continuous-Time Chaotic Oscillator
This paper presents a true random-bit generation through a continuous-time chaotic oscillator, which provides automatically chaotic signals and is fully implemented on 0.18 CMOS standard technology. Chaotic dynamics of the oscillator are exhibited in terms of chaotic strange attractor in phase-space domain. In order to achieve true-random property, a simple designed of post-processing method is...
