Langevin formulation of a subdiffusive continuous time random walk in physical time [PDF]
, 2015 Systems living in complex non equilibrated environments often exhibit subdiffusion characterized by a sublinear power-law scaling of the mean square displacement. One of the most common models to describe such subdiffusive dynamics is the continuous time

Global Nuclear Explosion Discrimination Using a Convolutional Neural Network
Geophysical Research Letters, 2023 Using P‐wave seismograms, we trained a seismic source classifier using a Convolutional Neural Network. We trained for three classes: earthquake P‐wave, underground nuclear explosion (UNE) P‐wave, and noise.

Analysis of Network Security Data Using Wavelet Transforms
Journal of Algorithms & Computational Technology, 2014 Data Analysis of Network Security is very important in intrusion detection and computer forensics. A lot of data mining methods to research it have been found, such as content-based queries and similarity searches to manage and use such data.

Coherent Resonat millenial-scale climate transitions triggered by massive meltwater pulses [PDF]
, 2003 The role of mean and stochastic freshwater forcing on the generation of millennial-scale climate variability in the North Atlantic is studied using a low-order coupled atmosphere–ocean–sea ice model.

Sound Event Detection for Human Safety and Security in Noisy Environments
IEEE Access, 2022 The objective of a sound event detector is to recognize anomalies in an audio clip and return their onset and offset. However, detecting sound events in noisy environments is a challenging task. This is due to the fact that in a real audio signal several

Dynamic mode decomposition of extreme events [PDF]
Nonlinear Processes in GeophysicsMost data-driven methods, among them Dynamic Mode Decomposition (DMD), focus on analysing and reconstructing the average behaviour of a system. However, the primary interest often lies in the anomalous behaviour, known as extreme events.

Resolving the ambiguous direction of arrival of weak meteor radar trail echoes [PDF]
Atmospheric Measurement Techniques, 2021 Meteor phenomena cause ionized plasmas that can be roughly divided into two distinctly different regimes: a dense and transient plasma region co-moving with the ablating meteoroid and a trail of diffusing plasma left in the atmosphere and moving with the

Subdiffusion via dynamical localization induced by thermal equilibrium fluctuations [PDF]
, 2017 We reveal the mechanism of subdiffusion which emerges in a straightforward, one dimensional classical nonequilibrium dynamics of a Brownian ratchet driven by both a time-periodic force and Gaussian white noise.

RoboTAP: Target priorities for robotic microlensing observations [PDF]
, 2017 Context. The ability to automatically select scientifically-important transient events from an alert stream of many such events, and to conduct follow-up observations in response, will become increasingly important in astronomy.
