Ahmad Ghiasi; Lewis Nkenyereye; Fawwaz Hazzazi dkk.

PLOS ONE, Vol. 19 No. 4 · 2024 · Inggris · PLOS Scopus

This research introduces a new designing process and analysis of an innovative Silicon-on-Insulator Metal-Semiconductor Field-Effect (SOI MESFET) structure that demonstrates improved DC and RF characteristics. The design incorporates several modifications to control and reduce the electric field…

Text-to-image generation with enhanced GANs: Bridging semantic gaps using RNN and CNN

Sadia Ramzan; Hafiz Arslan Ramzan; Tehmina Kalsum dkk.

PLOS One, Vol. 21 No. 1 · 2026 · Inggris · PLOS Scopus

Text-to-image generation is the process of generating images from a given text description. It is the most challenging task to produce consistently realistic images according to our conditions. We have considered this problem in our study and proposed a neural network-based model that can generate…

Error mitigation in LPWAN systems: A study on the efficacy of Hamming-coded RPW

Muhammad Moazzam Ali; Shaiful Jahari Hashim; Zaid Ahmad dkk.

PLOS ONE, Vol. 19 No. 6 · 2024 · Inggris · PLOS Scopus

Rotating Polarization Wave (RPW) is a novel Low Power Wide Area Networks (LPWAN) technology for robust connectivity and extended coverage area as compared to other LPWAN technologies such as LoRa and Sigfox when no error detection and correction is employed. Since, IoT and Machine-to-Machine (M2M)…

Comparative investigation of bagging enhanced machine learning for early detection of HCV infections using class imbalance technique with feature selection

Ekramul Haque Tusher; Mohd Arfian Ismail; Abdullah Akib dkk.

PLOS One, Vol. 20 No. 6 · 2025 · Inggris · PLOS Scopus

Around 1.5 million new cases of Hepatitis C Virus (HCV) are diagnosed globally each year (World Health Organization, 2023). Consequently, there is a pressing need for early diagnostic methods for HCV. This study investigates the prognostic accuracy of several ensemble machine learning (ML) models…

Novel high-performance microstrip diplexer for 5G mid-band and wide-band applications: Design, analysis and manufacturing

Salah I. Yahya; Farid Zubir; Mohammed Abdel Hafez dkk.

PLOS One, Vol. 20 No. 7 · 2025 · Inggris · PLOS Scopus

This paper presents the design and experimental results of a microstrip diplexer with a high performance for 5G applications. The introduced diplexer has compact size, novel structure, low losses, and wide fractional bandwidth. Notably, it exhibits a novel microstrip layout with a very compact size…

Design and fabrication of a microstrip triplexer with wide flat channels for multi-band 5G applications

Salah I. Yahya; Farid Zubir; Mohammed Abdel Hafez dkk.

PLOS ONE, Vol. 19 No. 5 · 2024 · Inggris · PLOS Scopus

In this paper, a new microstrip triplexer is designed to work at 2.5 GHz, 4.4 GHz and 6 GHz for mid-band 5G applications. All channels are flat with three low group delays (GDs) of 0.84 ns, 0.75 ns and 0.49 ns, respectively. Compared to the previously reported works, the proposed triplexer has the…
