New algorithm for the approximate solution of generalized seventh order Korteweg-Devries equation arising in shallow water waves
(Elsevier B.V., 2021)
In the present article, we present for the first time optimal auxiliary function method (OAFM) for partial differential equation (PDEs). To find efficient and precision the proposed method, we take Lax's seventh order ...
A Systematic Design of a Compact Wideband Hybrid Directional Coupler Based on Printed RGW Technology
(Institute of Electrical and Electronics Engineers Inc., 2021)
Printed ridge gap waveguide (PRGW) is considered among the state of art guiding technologies due to its low signal distortion and low loss at Millimeter Wave (mmWave) spectrum, which motivates the research community to use ...
A Comparison of Wireless Standards in IoT for Indoor Localization Using LoPy
(Institute of Electrical and Electronics Engineers Inc., 2021)
There are surplus applications in modern smart cities where localization of indoor environments is critical ranging from surveillance and trailing in smart structures to the localized wireless distribution of advertising ...
Routing in cognitive radio networks with full-duplex capability under dynamically varying spectrum availability
(Korean Institute of Communication Sciences, 2021)
This paper proposes a routing scheme for full-duplex-(FD)-based multi-hop CRNs that attempts to maximize the packet-delivery-ratio between any source–destination pair by being aware of the time-varying nature of ...
Chaos and bifurcation in time delayed third order phase-locked loop
(Institute of Advanced Engineering and Science, 2021)
In this paper, the modern nonlinear theory is applied to a third order phase locked loop (PLL) with a feedback time delay. Due to this delay, different behaviors that are not accounted for in a conventional PLL model are ...
Mathematical model on the effects of conductor thickness on the centre frequency at 28 GHz for the performance of microstrip patch antenna using air substrate for 5G application
(Elsevier, 2021)
The use of microstrip patch configuration in the 5th generation (5G) wireless network is
expected to fulfill the demands of smartphone users by significantly increasing the capacity of com munication technology. The main ...
A Joint Beamforming and Power-Splitter Optimization Technique for SWIPT in MISO-NOMA System
(Institute of Electrical and Electronics Engineers Inc., 2021)
In this paper, we propose a joint beamforming and power-splitter optimization technique for simultaneous wireless power and information transfer in the downlink transmission of a multiple-input single-output (MISO) ...
Energy, economic and environmental analysis of fuzzy logic controllers used in smart buildings
(Institute of Advanced Engineering and Science, 2021)
This article is divided into three parts: the first presents a simulation study of the effect of occupancy level on energy usage pattern of Engineering building of Applied Science Private university, Amman, Jordan. The ...
Analytical study of MHD mixed convection flow for Maxwell nanofluid with variable thermal conductivity and Soret and Dufour effects
(American Institute of Physics Inc., 2021)
The key purpose of this article is to discuss the magnetohydrodynamic mixed convection flow for a Maxwell nanofluid past a stretching and permeable sheet. Variable thermal conductivity and Dufour and Soret effects are also ...
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 ...
