Performance gap of two users in downlink full-duplex cooperative NOMA
A full-duplex non-orthogonal multiple access (FD-NOMA) systems are
expected to play a significant role in fifth generation (5G) networks,
addressing spectrum efficiency and massive connections. In this regard, the
feasibility of FD communications…

Power saving MAC protocols in wireless sensor networks: a survey
In a wireless sensor network, energy is almost always the greatest limitation.
Energy sources are restricted in many of the environments where nodes are
deployed, limiting them to the use of batteries for power. Therefore,
conserving energy is…

Blockchain-based adoption framework for authentic land registry system in Malaysia
Land registration systems are very essential for property ownership
management. The exited land registry systems are less efficient and time-
consuming and expose to human errors. By using blockchain technology,
most of the principles of good…

NLP analysis in social media using big data technologies
For timely and efficient reactions to disasters, collecting vital and right
information is essential. In recent decades, social media platforms such as
Twitter, Facebook, Linkedin, Instagram have become valuable sources of
information in disaster…

Extraction of object image features with gradation contour
Image retrieval using features has been used in previous studies including
shape, color, texture, but these features are lagging. With the selection of
high-level features with contours, this research is done with the hypothesis
that images on…

Design a new notched UWB antenna to rejected unwonted band for wireless communication
This paper presents a slotted design for ultra-wideband (UWB) antenna.
Design of a rectangular UWB antenna covering the frequency range 3.1-10.6
GHz, to achieve notch characteristics in the bands at 3.1-8.4 GHz and 8.6-
10.6 GHz. By changing the…

An effective new iterative CG-method to solve unconstrained non-linear optimization issues
In this paper, we proposed a matrix-free double-search direction based on the
updated parameter file of the double-search direction with a new
mathematical formula for the gamma parameter. When comparing the
numerical results of this algorithm…

The application of an age adjusted D-dimer threshold to rule out suspected venous thromboembolism (VTE) in an emergency department setting: a retrospective diagnostic cohort study
Background: Venous Thromboembolic disease (VTE) poses a diagnostic challenge for clinicians in acute care. Over
reliance on reference standard investigations can lead to over treatment and potential harm.
We sought to evaluate the pragmatic…

The efect of time of measurement on the discriminant ability for mortality in trauma of a pre-hospital shock index multiplied by age and divided by the Glasgow Coma Score: a registry study
Background: The shock index (SI) and its derivatives have been shown to predict mortality in severely injured
patients, both in pre-hospital and in-hospital settings. However, the impact of the time of measurement on the
discriminative ability of…

The impact of COVID-19 on an Irish Emergency Department (ED): a cross-sectional study exploring the factors infuencing ED utilisation prior to and during the pandemic from the patient perspective
Background: The collateral damage of SARS-CoV-2 is a serious concern in the Emergency Medicine (EM) community,
specifcally in relation to delayed care increasing morbidity and mortality in attendances unrelated to COVID-19. The
objectives of this…
