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.

Characterising anomalous transport in accretion disks from X-ray observations [PDF]
, 2001 Whilst direct observations of internal transport in accretion disks are not yet possible, measurement of the energy emitted from accreting astrophysical systems can provide useful information on the physical mechanisms at work.

A titanium-nitride near-infrared kinetic inductance photon-counting detector and its anomalous electrodynamics [PDF]
, 2012 We demonstrate single-photon counting at 1550 nm with titanium-nitride (TiN) microwave kinetic inductance detectors. Energy resolution of 0.4 eV and arrival-time resolution of 1.2 microseconds are achieved.

Can Anomalous Amplification be Attained Without Postselection? [PDF]
, 2016 We present a parameter estimation technique based on performing joint measurements of a weak interaction away from the weak-value-amplification approximation.

Fractional Brownian motion with a reflecting wall [PDF]
, 2018 Fractional Brownian motion, a stochastic process with long-time correlations between its increments, is a prototypical model for anomalous diffusion.

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

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

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.
