Improving the signal subtle feature extraction performance based on dual improved fractal box dimension eigenvectors [PDF]

open access: yesRoyal Society Open Science, 2018
Because of the limitations of the traditional fractal box-counting dimension algorithm in subtle feature extraction of radiation source signals, a dual improved generalized fractal box-counting dimension eigenvector algorithm is proposed.

Volume of Interest-Based Fractal Analysis of Huffaz’s Brain

open access: yesFractal and Fractional, 2022
The robust process in memorising the Quran is expected to cause neuroplasticity changes in the brain. To date, the analysis of neuroplasticity is limited in binary images because greyscale analysis requires the usage of more robust processing techniques.

Answer counting under guarded TGDs [PDF]

open access: yes, 2021
We study the complexity of answer counting for ontology-mediated queries and for querying under constraints, considering conjunctive queries and unions thereof (UCQs) as the query language and guarded TGDs as the ontology and constraint language ...

New Approaches to Fractal Dimension Estimation With Application to Gray-Scale Images

open access: yesIEEE Access, 2020
Two new approaches for calculating box-counting fractal dimension (FD) estimates for gray-scale images are considered to overcome some of the limitations of the standard box-counting method, which requires setting a threshold in a pre-processing step ...
