Approximation properties relative to continuous scale space for hybrid discretisations of Gaussian derivative operators

open access: yesFrontiers in Signal Processing
This paper presents an analysis of properties of two hybrid discretisation methods for Gaussian derivatives, based on convolutions with either the normalised sampled Gaussian kernel or the integrated Gaussian kernel followed by central differences.

A probabilistic framework for modeling chloride‐induced corrosion and related load‐deformation behaviour of reinforced concrete

open access: yesStructural Concrete, EarlyView.
Abstract Chloride‐exposed reinforced‐concrete structures often suffer localized corrosion, so corrosion initiation time and average steel loss are poor indicators of structural performance. This paper presents a spatially resolved, proof‐of‐concept framework that couples diffusion‐based chloride ingress and initiation with a localized morphology model ...

Log data analysis through tick discretisation [PDF]

open access: yes, 2016
Nowadays almost every major company has a monitoring system and produces log data to analyse their systems. To perform analysation on the log data and to extract experience for future decisions it is important to transform and synchronize different time ...

Modelling of continuously distributed target for bistatic synthetic aperture radar imaging

open access: yesThe Journal of Engineering, 2020
The point target model is widely used in the synthetic aperture radar (SAR) imaging simulation. Based on this model, the radar echo of a continuously distributed target can be expressed as the linear summation of the echo of many point targets which are ...

Double‐Integration‐Enhanced Stochastic Gradient Descent Based on Neural Dynamics for Improving Generalisation

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Generalisation is a crucial aspect of deep learning, enabling models to perform well on unseen data. Currently, most optimisers that improve generalisation typically suffer from efficiency bottlenecks. This paper proposes a double‐integration‐enhanced stochastic gradient descent (DIESGD) optimiser, which treats the negative gradient as an ...

Cascade Deep Learning With Physics Guidance for Typhoon Intensity Prediction

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Typhoons pose a significant threat to both human safety and economic stability. As a crucial metric for assessing their destructive potential, typhoon intensity (TI) prediction has become an important research focus, with numerous methods developed.

FPGA‐Based Real‐Time Implementation of Closed‐Loop Brain‐Controlled Eye Movement System

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT This paper presents a comprehensive closed‐loop brain‐eye movement framework, spanning parametric modelling, dynamic analysis and real‐time FPGA implementation. A simplified first‐order oculomotor model was derived from the classical Robinson formulation to preserve the essential neural‐mechanical feedback structure while enabling efficient ...

A Validation Method for the Enhanced Fuzzy Min‐Max Neural Network With Application to Heart Disease Data Classification

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT This study investigates early detection of heart diseases using a new Enhanced Fuzzy Min‐Max (EFMM) neural network. Two key modifications are introduced: a refined EFMM contraction procedure during the learning phase to reduce data distortion and information loss, and a new weighted validation method to optimise hyperbox selection and improve ...

Holistic discretisation of shear dispersion in a two-dimensional channel [PDF]

open access: yes, 2003
Consider the spread of a contaminant along a 2D channel or river. We directly derive the 1D discrete numerical model from the 2D advective and diffusive dynamics for the evolution of the contaminant.
