An intelligent maximum power point solar tracking system
(Institut za Istrazivanja, 2019)
This paper accentuates the enhancement of electric energy produced from Photo Voltaic (PV) solar modules as a result of sun tracking. The development of the tracking system is based on finding the orientation of a solar ...
Yet efficient routing protocols for half- and full-duplex cognitive radio Ad-Hoc Networks over IoT environment
(Academic Press, 2021)
For the sake of fulfilling the ever-increasing demands on the Internet of Things (IoT) applications, researchers are implementing Cognitive Radio (CR) technology in Ad-Hoc Networks (AHNs). Moreover, In-Band Full-Duplex ...
Mathematical analysis of COVID-19 via new mathematical model
(Elsevier Ltd., 2021)
We develop a new mathematical model by including the resistive class together with quarantine class and use it to investigate the transmission dynamics of the novel corona virus disease (COVID-19). Our developed model ...
Mapping information technology infrastructure library with other information technology standards and best practices
(Science Publications, 2013)
Information Technology (IT) has become an important strategic resource that any organization has to manage. It has been recognized that IT services are crucial and strategic organizational assets, therefore, organizations ...
A compact UWB antenna with independently controllable notch bands
(MDPI AG., 2019)
A minimally-sized, triple-notched band ultra-wideband (UWB) antenna, useful for many applications, is designed, analyzed, and experimentally validated in this paper. A modified maple leaf-shaped main radiating element with ...
Cylindrical dielectric resonator antenna-based sensors for liquid chemical detection
(MDPI AG., 2019)
A compact, cylindrical dielectric resonator antenna (CDRA), using radio frequency signals to identify different liquids is proposed in this paper. The proposed CDRA sensor is excited by a rectangular slot through a 3-mm-wide ...
Multi-Person Tracking and Crowd Behavior Detection via Particles Gradient Motion Descriptor and Improved Entropy Classifier
(MDPI AG., 2021)
To prevent disasters and to control and supervise crowds, automated video surveillance has become indispensable. In today’s complex and crowded environments, manual surveillance and monitoring systems are inefficient, labor ...
Low-profile frequency reconfigurable antenna for heterogeneous wireless systems
(MDPI AG., 2019)
A low-profile (0.21λg× 0.35λg× 0.02λg ) and a simply-structured frequency-switchable antenna with eight frequency choices is presented in this paper. The radiating structure (monopole) is printed on a 1.6-mm thicker, ...
Youths interests in the biosphere and sensitivity to nuclear power technology in the UAE: With discussions on open innovation and technological convergence in energy and water sectors
(MDPI AG., 2020)
Nuclear power technology (NPT) perception and acceptance have globally emerged as the most critical questions for the successful integration of NPT into any national energy mix. In its combination with seawater desalination, ...
A smart surveillance system for people counting and tracking using particle flow and modified som
(MDPI AG., 2021)
Based on the rapid increase in the demand for people counting and tracking systems for surveillance applications, there is a critical need for more accurate, efficient, and reliable systems. The main goal of this study was ...
