Objective patterns in the evolving network of non-equivalent observers
The world's objective pattern is formed through consistent histories of quantum measurements originating as different branches of the same wave function. When we come close to the limits of measurement (either by approaching the speed of light or the values of the Planck's quantum), the relational effects come into place and the objectivity of world's pattern melts down. But when we are positio...
متن کاملHealthy Older Observers Show Equivalent Perceptual-Cognitive Training Benefits to Young Adults for Multiple Object Tracking
The capacity to process complex dynamic scenes is of critical importance in real life. For instance, traveling through a crowd while avoiding collisions and maintaining orientation and good motor control requires fluent and continuous perceptual-cognitive processing. It is well documented that effects of healthy aging can influence perceptual-cognitive processes (Faubert, 2002) and that the eff...
متن کاملA class of cellular automata equivalent to deterministic particle systems
We demonstrate that a local mapping f in a space of bisequences over {0, 1} which conserves the number of nonzero sites can be viewed as a deterministic particle system evolving according to a local mapping in a space of increasing bisequences over Z. We present an algorithm for determination of the local mapping in the space of particle coordinates corresponding to the local mapping f .
متن کاملAn exploration of the equivalent weights particle filter
Particle filters are fully non-linear data assimilation techniques that aim to represent the probability distribution of the model state given the observations (the posterior) by a number of particles. In high-dimensional geophysical applications the number of particles required by the sequential importance resampling (SIR) particle filter in order to capture the high probability region of the ...
متن کاملThe equivalent-weights particle filter in a high-dimensional system
In general, particle filters need large numbers of model runs in order to avoid filter degeneracy in high-dimensional systems. The recently proposed, fully nonlinear equivalentweights particle filter overcomes this requirement by replacing the standard model transition density with two different proposal transition densities. The first proposal density is used to relax all particles towards the...
