After performing data preprocessing and acquiring spectrograms, the data is then subjected to the ZFNet/Extreme Learning Machine (ELM) approach for the goal of data modification, extraction of features, and recognition.

To extract the features of…

Dataset and evaluation metrics

Dataset.To validate the efficacy of the proposed method for the diagnosis of bearing faults, we used four renowned public datasets: the Case Western Reserve University dataset (CWRU)⁵⁴, the Jiangnan University…

Current research indicates that voltage instability is one of the primary challenges in power systems with intermittent PV power generation^25,26,27. The peak and valley values of PV power generation have a significant impact on the stability of…

Shear force-shear displacement curve

According to the different normal stress and tangential force data recorded in the test process, the shear force-shear displacement curve was plotted, as shown in Fig. 8. The different stages are divided based…

Heuristic schemes have played a crucial role in handling a broad variety of optimization problems, both unconstrained and constrained, across diverse engineering fields. These schemes were developed to provide approximate/optimal solutions to…

Catalyst properties

XRD and FTIR

Figure 1 displays the XRD patterns of the PET, TiO₂ and TiO₂/PET composite. The XRD study for the PET revealed 2θ values of 18.1°, 23.4° and 25.8° in relation to the (010), (110), and (100) planes,…

With the accelerated integration of distributed generation, DC microgrids (DC-MGs) have been gaining much popularity and attention compared to AC-MGs. This shift is primarily attributed to the inherent DC characteristics of emerging distributed…

The methodology employed for the processing and classification of pure-tone audiometry test results on mobile devices can be delineated into three distinct stages: scanning, digitization and classification of audiograms. The initial stage,…

Dataset presentation

Divided into two main classes—Foul and Not Foul—the 7000 images used in this study are from actual football match video. Each Foul scenario was kept in a different subfolder in each of the many folders the dataset was…

To demonstrate the importance of MPPT technology, different methods have been applied and compared with the PWM technique. All proposed methods have been run on MATLAB software 2019a, a 3.20 GHz AMD Ryzen 7 5800 H PC with 16 GB RAM. The…
