Propagation of Uncertainty from Random Error00:59

Propagation of Uncertainty from Random Error

1.6K
An experiment often consists of more than a single step. In this case, measurements at each step give rise to uncertainty. Because the measurements occur in successive steps, the uncertainty in one step necessarily contributes to that in the subsequent step. As we perform statistical analysis on these types of experiments, we must learn to account for the propagation of uncertainty from one step to the next. The propagation of uncertainty depends on the type of arithmetic operation performed on...

Random Variables

17.0K
A random variable is a single numerical value that indicates the outcome of a procedure. The concept of random variables is fundamental to the probability theory and was introduced by a Russian mathematician, Pafnuty Chebyshev, in the mid-nineteenth century.
Uppercase letters such as X or Y denote a random variable. Lowercase letters like x or y denote the value of a random variable. If X is a random variable, then X is written in words, and x is given as a number.
For example, let X = the...

Area of Science:

  • Physics
  • Engineering
  • Chaos Theory

Background:

  • Hardware random number generators are crucial for secure communications and simulations.
  • Chaos theory provides a framework for generating unpredictable behavior.
  • Nanoelectromechanical systems (NEMS) offer miniaturized platforms for physical phenomena.

Purpose of the Study:

  • To theoretically investigate the potential of a nanoelectromechanical suspended beam resonator as a hardware random number generator.
  • To assess the randomness of chaotic oscillations in a NEMS resonator.
  • To evaluate the performance of the generated random numbers in physical simulations.

Main Methods:

  • Theoretical modeling of a nanoelectromechanical suspended beam resonator.
  • Excitation of the resonator using two external frequencies to induce robust chaos.
  • Analysis of the beam's position as a random variable.
  • Statistical testing of the generated number sequences for randomness.
  • Simulation of the random walk and Ising model using the generated numbers.

Main Results:

  • The nanoelectromechanical resonator exhibits robust chaotic oscillations when driven by two external frequencies.
  • Statistical tests confirm that the beam position data forms a high-quality random number sequence.
  • The generated random numbers demonstrate excellent performance in simulating the random walk and Ising model.

Conclusions:
