Published in: IEEE Transactions on Antennas and Propagation
Sep 11, 2024
This article presents a compact self-quadruplexing antenna for scalp-implantable devices. The proposed self-quadruplexing antenna operates at 168 MHz [industrial, scientific, and medical (ISM) band], 433 MHz (ISM band), 915 MHz (ISM band), and 1400 MHz [wireless medical telemetry service (WMTS) band] when Ports 1, 2, 3, and 4 are activated, respectively. The proposed antenna is simulated inside a rectangular device in the head of a human phantom. The suggested antenna comprises four individuall...
A numerical investigation of the chemically reactive maxwell nanofluid flow over a convectively heated rotating disk using Darcy-Forchheimer porous medium

This study investigates the convective heat transfer characteristics in the vicinity of a stagnation point for the flow of Maxwell nanofluid over a porous rotating disk. The analysis takes into account the complex inert-active effects arising from nonlinear thermal radiation, activation energy, and the presence of a Darcy-Forchheimer medium. Through numerical simulations, the enhancement of heat transfer due to the addition of nanoparticles is explored, considering their impact on heat transpor...
Dufour and Soret diffusions phenomena for the chemically reactive MHD viscous fluid flow across a stretching sheet with variable properties

The flow of fluid on a slandering stretchable sheet with variable thickness can have several engineering applications like design and optimization of, aerodynamic structures such as wings and airfoils, wind turbine blade design, efficient cooling systems for electronic devices, power plants and industrial processes. Keeping in view these important applications, this work explores Darcy-Forchheimer flow of magnetohydrodynamics (MHD) fluid across a slandering stretchable sheet with variable thick...
BOC-PDO: An intrusion detection model using binary opposition cellular prairie dog optimization algorithm
Published in: Cluster Computing
Jul 20, 2024
Intrusion detection datasets are highly likely to contain numerous redundant, irrelevant, and noisy features that slow the performance of the machine learning techniques and classifiers that may be applied to them. The feature selection approach is used for reducing the number of features in intrusion detection datasets and eliminating those that are not important. One of the most powerful structured population approaches is the Cellular Automata approach, which is used to enhance the diversity...

This paper introduces a novel self-triplexing implantable antenna designed to operate in head implants. It works at three distinct frequency bands: 403 MHz on Port 1, 915 MHz on Port 2, and 1410 MHz on Port 3. The antenna design incorporates a high-permittivity laminate and triangular meandered resonators, which extend the current path and enable significant miniaturization. The resulting antenna occupies a volume of only 8 mm × 12.5 mm × 0.3 mm (30 mm3). An ultra-thin substrate of 0.3 mm is ut...
