Pointwise Convergence of Wavelet Expansions

open access: yes, 1994
In this note we announce that under general hypotheses, wavelet-type expansions (of functions in L p ; 1 p 1, in one or more dimensions) converge pointwise almost everywhere, and identify the Lebesgue set of a function as a set of full measure on ...

Deep learning‐based super‐resolution reconstruction and improved YOLOv9 for efficient benthos detection: a case study at Lake Hamana, Japan

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study presents a UAV‐based framework that integrates deep learning‐based super‐resolution reconstruction and an enhanced YOLO detector to improve centimetre‐scale benthic organism monitoring. Using hermit crabs in Lake Hamana, a coastal lagoon in Japan, as a case study, the method substantially enhanced small‐object detection performance ...

Abstract Theorems on Exchange of Limits and Preservation of (Semi)continuity of Functions and Measures in the Filter Convergence Setting

open access: yesJournal of Function Spaces, 2016
We give necessary and sufficient conditions for exchange of limits of double-indexed families, taking values in sets endowed with an abstract structure of convergence, and for preservation of continuity or semicontinuity of the limit family, with respect

Pointwise convergence of gradient‐like systems

open access: yesMathematische Nachrichten, 2007
AbstractS. Łojasiewicz has shown that the ω ‐limit sets of the trajectories of analytic gradient systems consist of at most one point. We extend this result to the larger class of gradient‐like vector fields satisfying an angle condition. In particular, this includes gradient systems, defined by arbitrary C1 functions from an analytic‐geometric ...

Synergies of Geospatial and Digital Technologies for Sustainable Rural Development: A Data‐Driven Analysis of Topics and Novelty Assessment

open access: yesSustainable Development, EarlyView.
ABSTRACT The adoption of geospatial and digital technologies, including Geographic Information Systems (GIS), Building Information Modelling (BIM), Digital Twins, the Internet of Things (IoT) and Artificial Intelligence (AI), is increasingly recognised as key enablers of sustainable development.

A Physics‐Aware Lightweight Transformer Network for Intelligent Bearing Fault Diagnosis Under Variable Operating Conditions

open access: yesArtificial Intelligence for Engineering, EarlyView.
A physics‐aware lightweight transformer converts vibration signals into overlapping patch to kens aligned with bearing defect frequencies, enabling amplitude‐invariant self‐attention that generalises across variable load conditions, achieving 99.2% accuracy with 0.52 M parameters and 8.2 ms inference for real‐time edge deployment.

Uniform convergence and pointwise convergence

open access: yes, 2017
The aim of this material is to introduce the student to two notions of convergence for sequences of real-valued functions. The notion of pointwise convergence is relatively straightforward, but the notion of uniform convergence is more subtle.

Nonparametric estimation of distributions with given marginals via Bernstein–Kantorovich polynomials: L1 and pointwise convergence theory

open access: yes, 2007
The copula density is estimated using Bernstein–Kantorovich polynomials. The estimator is the usual one based on the smoothed histogram. Strong consistency is obtained in L1 and pointwise almost everywhere, allowing for dependent data. For L1 convergence,

Fault‐Tolerant Fuzzy Boundary Control for Nonlinear Distributed Parameter Systems Under Limited Measurements and Markovian Failures

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT This paper proposes a boundary control method for nonlinear distributed parameter systems (DPSs) with limited boundary measurements (BMs), as typically encountered in networked cyber‐physical processes with spatially distributed dynamics such as thermal and biomedical diffusion systems.
