Imbalanced data handling in multiclass distributed denial of service attack detection using deep learning
In data analysis, imbalanced datasets are a frequent issue, where classes in a dataset have an uneven distribution, which can lead to poor performance in machine learning (ML) and predictive modeling. In this study, we analyze distributed denial of…
Impact study on indirect lightning strikes on photovoltaic systems near transmission lines
Grid-integrated photovoltaic (PV) systems are currently undergoing explosive growth in Malaysia. However, as more PV systems are installed close to transmission lines, there are concerns about the impact of electromagnetic (EM) properties affecting…
IR4.0 and internet of things: future directions towards enhanced connectivity, automation, and sustainable innovation
This study provides a systematic review of the literature on the fourth industrial revolution (IR4.0) and the internet of things (IoT) in genetics, informatics, and biotechnology, as well as their many rapidly evolving applications, which often…
Light weight dual polarized horn antenna for polarimetry C-band synthetic aperture radar sensor onboard UAV
Unmanned aerial vehicles (UAVs) can collect earth surface information with synthetic aperture radar (SAR) sensors during night, day, and bad weather. However, UAVs have only limited volume and weight for the SAR payload. A very light dual circularly…
Malaysian fibre internet service provider: a naïve Bayes classification Twitter sentiment analysis
In the highly competitive landscape of Malaysian internet service providers (ISPs), users seek efficient ways to assess service quality. While various websites allow visual comparisons of fiber ISPs, a direct side-by-side evaluation remains elusive.…
Modeling and optimization of artificial magnetic conductor on the performance of on-chip-antenna for 28 GHz devices
The growing popularity of chip-based devices has spurred interest in developing on-chip antennas (OCAs). However, low gain and poor radiation characteristics have been significant challenges. Integrating an artificial magnetic conductor (AMC) into…
Multi-step constant current-constant voltage charging method to improve CC-CV method on lead acid batteries
Constant current-constant voltage (CC-CV) is one of the battery charging methods that is commonly used. However, this method has several drawbacks, including the charging current in constant current (CC) mode, which can only be set to a maximum of…
Optimation of image encryption using fractal Tromino and polynomial Chebyshev based on chaotic matrix
Image encryption is a critical process aimed at securing digital images, safeguarding them from unauthorized access, tampering, or viewing to ensure the confidentiality and integrity of sensitive visual information. In this research, we integrate…
Performance analysis of terrestrial 6G networks in tropical region
Next-generation (NG) optical technologies are expected to offer high data rates, multiple broadband services, expandable bandwidth, and flexible communication options for diverse end users. In optical technologies, free space optical (FSO) technology…
Performance of piezoelectric energy harvesters at various angles
Piezoelectric materials are capable of generating electricity in response to mechanical strain, making them suitable for energy harvesting applications. Piezoelectric energy harvesters (PEHs) are promising alternatives for renewable energy…
