A threshold-based opportunistic MAC protocol for MIMO wireless sensor networks
(
IEEE
, 2012 , Conference Paper)
In this paper, we consider a single-hop wireless sensor network where both the sensor nodes and the controller node have multiple antennas. We focus on single beam opportunistic communication and propose a threshold-based ...
Drill string nonlinear vibrations: Experimental studies and finite-element analysis
(
Institute of Physics Publishing
, 2018 , Conference Paper)
In the present work, nonlinear vibrations of drill strings are studied. A laboratory scale arrangement consisting of a flexible rod with rotor-stator system is used to study the system dynamics. A finite-element model has ...
Loading Rates of Dust and Metals in Residential Houses of Arid and Dry Climatic Regions
(
Taiwan Association for Aerosol Research
, 2016 , Article)
Dust samples were collected from 38 naturally ventilated houses for 12 weeks. Effects of three variables in two groups each were evaluated: proximity to traffic density (main- and side-roads), cigarettes smoking (smoking ...
Medical comorbidities in patients with serious mental illness: A retrospective study of mental health patients attending an outpatient clinic in Qatar
(
Dove Medical Press Ltd.
, 2017 , Article)
Background: The life span of individuals with serious mental illness (SMI) is shorter compared to the general population. This excess mortality is mainly due to physical illness. The aim of the study was to investigate the ...
A Fatigue Measuring Protocol for Wireless Body Area Sensor Networks
(
Springer New York LLC
, 2015 , Article)
As players and soldiers preform strenuous exercises and do difficult and tiring duties, they are usually the common victims of muscular fatigue. Keeping this in mind, we propose FAtigue MEasurement (FAME) protocol for ...
The purification and identification of human blood serum proteins with affinity to the antitumor active RL2 lactaptin using magnetic microparticles
(
John Wiley and Sons Ltd
, 2019 , Article)
The cytopoxic effect of RL2 lactaptin (the recombinant analog of proteolytic fragment of human kappa‐casein) toward tumor cells in vitro and in vivo presents it as a novel promising antitumor drug. The binding of any drug ...
Minimising number of sensors in wireless sensor networks for structure health monitoring systems
(
Institution of Engineering and Technology
, 2019 , Article)
Sensor placement optimisation is an important problem in the field of structural health monitoring (SHM). Many researchers solve this problem by focusing only on the network requirements, without considering the civil ...
A boundary integral method for the general conjugation problem in multiply connected circle domains
(
Springer International Publishing
, 2018 , Article)
We present a boundary integral method for solving a certain class of Riemann-Hilbert problems known as the general conjugation problem. The method is based on a uniquely solvable boundary integral equation with the generalized ...
Social workers in a Qatari health setting: responding positively to ethical problems
(
Routledge
, 2016 , Article)
Social workers in health settings often face challenging ethical problems in their daily practice. These challenges may be internal in nature and in particular related to their personal and cultural beliefs. The aim of ...
The adoption of green building practices in construction projects in Qatar: a preliminary study
(
Emerald Group Publishing Ltd.
, 2019 , Article)
Purpose
It is widely known that carbon dioxide emissions and climate change are among the most critical global challenges. These issues were worsened partly by the continuous adoption of traditional non-green behaviors ...
