In video games using procedural world generation, the map seed is a (relatively) short number or text string which is used to procedurally create the game world ("map"). "). This means that while the seed-unique generated map may be many megabytes in size (often generated incrementally and virtually unlimited in potential size), it is possible to reset to the unmodified map, or the unmodified ...
The ESO Supernova Planetarum & Visitor Centre is located at the Science Campus Garching. The campus is home to the Ludwig-Maximilians University of Munich and the Technical University of Munich, in addition to more than 80 independent scientific institutions and international science companies, 6 000 staff members and 14 000 students.
The diamagnetic drift is not actually a guiding center drift and resembles averaged (fluid) behavior of large collection of particles. A pressure gradient does not cause any single particle to drift. Nevertheless, the fluid velocity is defined by counting the particles moving through a reference area, and a pressure gradient results in more ...

Shorter codes are reserved for densely populated areas. The last idea, especially, yields very good results. For example, although every location within the Netherlands can be identified by a 6-letter mapcode, half of the Dutch population can be found in about 40 cities and densely populated areas that together comprise less than 6,000 square ...
This Wiener process (Brownian motion) in three-dimensional space (one sample path shown) is an example of an Itô diffusion.. A (time-homogeneous) Itô diffusion in n-dimensional Euclidean space is a process X : [0, +∞) × Ω → R n defined on a probability space (Ω, Σ, P) and satisfying a stochastic differential equation of the form
For n ≥ 2, the n-dimensional Wiener process started at the origin is transient from its starting point: with probability one, i.e., X t > 0 for all t > 0. It is, however, neighbourhood-recurrent for n = 2, meaning that with probability 1, for any r > 0, there are arbitrarily large t with X t < r; on the other hand, it is truly transient for n > 2, meaning that X t ≥ r for all t ...
In predictive analytics, data science, machine learning and related fields, concept drift or drift is an evolution of data that invalidates the data model.It happens when the statistical properties of the target variable, which the model is trying to predict, change over time in unforeseen ways.
