Novel design for thermal management of PV cells in harsh environmental conditions
(
MDPI AG
, 2018 , Article)
The abundance of solar energy is a blessing in the Arabian Peninsula, where more than 2000 kWh/m2 density has been recorded annually. This has resulted in sincere consideration of PV harvesting in the energy matrix and ...
Surface-type nonvolatile electric memory elements based on organic-on-organic CuPc-H
(
Institute of Physics Publishing
, 2015 , Article)
A novel surface-type nonvolatile electric memory elements based on organic semiconductors CuPc and H2Pc are fabricated by vacuum deposition of the CuPc and H2Pc films on preliminary deposited metallic (Ag and Cu) electrodes. ...
New fast arctangent approximation algorithm for generic real-time embedded applications
(
MDPI AG
, 2019 , Article)
Fast and accurate arctangent approximations are used in several contemporary applications, including embedded systems, signal processing, radar, and power systems. Three main approximation techniques are well-established ...
Experimental setup to validate the effects of major environmental parameters on the performance of FSO communication link in Qatar
(
MDPI AG
, 2018 , Article)
Weather conditions and chemical composition of the atmosphere are the most uncontrollable challenges for free-space optical (FSO) communications. Environmental parameters contribute directly in the characterization of ...
A modular IoT platform for real-time indoor air quality monitoring
(
MDPI AG
, 2018 , Article)
The impact of air quality on health and on life comfort is well established. In many societies, vulnerable elderly and young populations spend most of their time indoors. Therefore, indoor air quality monitoring (IAQM) is ...
A real-time early warning seismic event detection algorithm using smart geo-spatial bi-axial inclinometer nodes for Industry 4.0 applications
(
MDPI AG
, 2019 , Article)
Earthquakes are one of the major natural calamities as well as a prime subject of interest for seismologists, state agencies, and ground motion instrumentation scientists. The real-time data analysis of multi-sensor ...
Geographical area network-structural health monitoring utility computing model
(
MDPI AG
, 2019 , Article)
In view of intensified disasters and fatalities caused by natural phenomena and geographical expansion, there is a pressing need for a more effective environment logging for a better management and urban planning. This ...
A fuzzy logic based irrigation system enhanced with wireless data logging applied to the state of Qatar
(
Elsevier B.V.
, 2013 , Article)
In arid regions, developing environment and crop-specific irrigation scheduling that reduces water lost via evapotranspiration is a key to a sustainable and better managed irrigation. This paper presents a practical solution ...
A BHJ-thin-film/liquid-electrolyte based electrochemical-sensor for visible light-detection
(
Royal Society of Chemistry
, 2017 , Article)
The current study presents a new type of inexpensive and very sensitive bulk heterojunction (BHJ) organic photo-sensor (OPS) configuration that incorporates a layer of liquid electrolyte into the conventional BHJ photodiode ...
Global dissipativity of high-order Hopfield bidirectional associative memory neural networks with mixed delays
(
Springer
, 2020 , Article)
In this paper, the problem of the global dissipativity of high-order Hopfield bidirectional associative memory neural networks with time-varying coefficients and distributed delays is discussed. By using Lyapunov?Krasovskii ...
