Web30 nov. 2024 · 1 Answer Sorted by: 2 X a ( t) = 1 a X ( a 2 t) is a Standard Brownian Motion ( X ( a 2 t) )is a general Brownian motion with mean 0). Any Gaussian stochastic process is completely specified by its expectation and covariance function. It is enough to prove that X a ( t) has correct mean and covariance. Web28 jan. 2024 · Temperature. If matter is heated and thus its temperature rises more and more, it can be seen that the particles contained in it move ever faster – be it the relatively free movement of the particles in gases or the oscillation around a rest position in solids. Animation: Influence of temperature on particle motion and thermal expansion.

Web12 jul. 2015 · QUESTION: Show that X ( t) = t W ( 1 / t) is a Brownian motion if W ( t) is a Brownian motion. As a hint, we are told that we need to check that lim t → 0 X ( t) = 0 a.s. ANSWER: Like W ( t), X ( t) is also a Gaussian process. We need to check that E ( X ( t) X ( s)) = min ( t, s). I checked it and it is correct.
