Power evaluation and performance enhancement of CSMA/CA based WLANs.
… lower than the International Commission on Non-Ionizing Radiation Protection (ICNIRP) limit; (2) We propose two decentralized Multiple Access Control (MAC) schemes that converge to collision-free schedules almost surely and therefore improve throughput performance. In adopting decentralized …

Synergistic Combination of Microwaves and Acoustic Signals: Towards Improved Breast Imaging
… scans involving no breast compression, non-ionizing radiation, inexpensive scan costs, sensitivity to water content and low-complexity 3D image reconstruction. These benefits are well-suited for its application in breast health monitoring and treatment surveillance for which there is no …

NEAR INFRARED SPECTROSCOPIC ASSESSMENT OF BONE WATER BINDING TO COLLAGEN AND MINERAL
… known as near infrared spectroscopy (NIRS) is a nondestructive modality that can spatially evaluate alterations of bone composition. NIRS is a unique nondestructive technique that produces a signature spectrum by penetrating high frequency (4000-12,000 cm-1) non-ionizing radiation into material. …

Design and characterisation of wideband antennas for microwave imaging applications
… because the scanner exposes patients to more radiations of ionised frequency. The limitations of the equipment create a need to design an alternative imaging method which is relatively low cost, small in size, has high mobility, and non-ionise frequency. This research is to design an antenna …

Photoacoustic Reporter Gene Imaging And Optical Coherence Computed Tomography
… perspective, optical systems utilize safe non-ionizing radiation, could be implemented at relatively low cost, also have the potential to be miniaturized for portable or endoscopic applications. As a result, optical imaging tools are playing an increasingly important role in both …

Developing a Microbubble-based Contrast Agent for X-ray Phase Contrast Imaging to Detect Neovasculature in Breast Cancer
… can be performed at high energy, so the absorbed radiation is reduced. Ultrasound microbubbles (MBs) with biocompatible composition and gas content can maximize the X-ray refraction and scattering. Multiple studies have investigated MBs and XPC, but they share a common feature: no uniform …

RF-EMF Radiation Exposure and Radio Resources Management in 5G Wireless Network
… and radiofrequency electromagnetic field (RFEMF) radiation exposure (a health challenge on user) emitted in both the uplink and downlink of wireless networks, especially the 5G mobile network. Therefore, this research aims to assess the impacts of these challenges, develop and evaluate efficient …
