Fractional statistics in anyon collisions
2020
Science
Two-dimensional systems can host exotic particles called anyons whose quantum statistics are neither bosonic nor fermionic. ...
For example, the elementary excitations of the fractional quantum Hall effect at filling factor ν = 1/m (where m is an odd integer) have been predicted to obey Abelian fractional statistics, with a phase ...
The fractional quantum Hall effect 4, 5 , obtained by applying a strong magnetic field perpendicular to a two-dimensional electron gas, is one of the physical systems predicted to host anyons. ...

Cell dynamics simulation of Kolmogorov–Johnson–Mehl–Avrami kinetics of phase transformation: One and two-dimensional cases
2007
Materials Science & Engineering: A
We find that the cell dynamics method reproduces the time evolution of the volume fraction of the transformed phase predicted by the KJMA theory. ...
Specifically, the cell dynamics simulation reproduces a double-logarithmic linear KJMA plot and confirms the integral Avrami exponents n predicted from the KJMA theory. ...
We found a nearly linear behavior of the KJMA plot with the Avrami exponent close to the KJMA predicted value. ...

A Linear Prediction Based Fractional-Pixel Motion Estimation Algorithm
2010
2010 4th International Conference on Multimedia and Ubiquitous Engineering
To tackle these problems, a center-biased fast fractional-pixel ME algorithm using linear prediction based search with intrinsic center-biased characteristic is developed in this paper. ...
Fast fractional-pixel ME algorithms were therefore developed, in which initial search point is first predicted before applying fast refinement search. ...
One-dimensional or two-dimensional quadratic functions are employed in [12] and [13] respectively to predict the initial search point. ...

A Machine Learning Approach For Simulating Ground Penetrating Radar

2018 17th International Conference on Ground Penetrating Radar (GPR)
Based on these parameters and the synthetically generated training set, a machine learning framework is trained to predict the resulting A-Scan in real-time. ...
Through a stochastic parameterisation, each model is expressed using only seven parameters (i.e. the fractal dimension of water fraction, the heigh of the antenna and so on). ...
The first two layers use sigmoid activation functions while the last layer uses a linear one in order to predict the continuous nature of the compressed A-Scan. ...

The results indicate that there is no significant difference in the predictability of the void fraction between one- and multi-dimensional components. ...
A further assessment has been performed using two thermal-hydraulic system codes, TRACE V5.0 patch 5 and MARS-KS 1.4, and the assessment has been carried out for both one- and multi-dimensional components ...
