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…
High-efficiency rectifier achieves 63% power conversion in low start-up voltage for UHF RFID tags in 180 nm CMOS technology
This paper presents an N-metal-oxide semiconductor (NMOS) rectifier designed for efficient radio frequency (RF) energy harvesting and wireless power transmission in passive ultra-high frequency (UHF) radio frequency identification (RFID)…
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.…
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…
Compact miniaturized antenna design and development for a leadless cardiac pacemaker
Biomedical antennas play a crucial role in implantable medical telemetry, improving patient monitoring and overall well-being. This study presents a compact antenna designed for a lead-free pacemaker, with dimensions of 3.3×4×0.5 mm³. Miniaturization…
Research on intelligent river water quality management system using blockchain-internet of things
Each and every living thing needs fresh water to survive. Fresh water is becoming a precious resource as a result of the combined risks of rapid urbanization, pollution, and climatic changes. The quality of the water we drink every day has an impact…
Sentiment analysis of public response to measurable fishing capture policy using LDA and LSTM methods
Illegal, unreported, and unregulated (IUU) fishing poses a significant threat by depleting fish stocks, damaging marine ecosystems, jeopardizing economic livelihoods, and undermining long-term environmental sustainability. To address this, the…
Development of an IoT based smart potato leaf diseases monitoring and controlling system with image processing
Potato (Solanum tuberosum L.) is a key crop and a major source of livelihood for a vast population of the world after wheat and rice. However, diseases have diverse effects on potato fields, leading to damage to crops and reducing crop production.…
Reducing feature dimensionality for cloud image classification using local binary patterns descriptor
Clouds play a crucial role in precipitation and weather prediction. Identifying and differentiating clouds accurately poses a significant challenge. In this paper, we present a novel approach that utilizes the local binary patterns (LBP) feature…
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…
