Mathematical Modelling for Predicting Thermal Properties of Selected Limestone
(MDPI, 2022)
Due to a lack of geotechnical and geothermal studies on Jordanian limestone, this paper aims to provide the thermal properties, including thermal conductivity, thermal diffusivity, and specific heat, using the Hot Disk ...
An innovative fractal monopole MIMO antenna for modern 5G applications
(Elsevier GmbH, 2023)
Proposed in this paper is the design of an innovative and compact antenna array which based on four radiating elements for multi-input multi-output (MIMO) antenna applications used in 5G communication systems. The radiating ...
Analysis of Challenges and Solutions of IoT in Smart Grids Using AI and Machine Learning Techniques: A Review
(MDPI, 2023)
With the assistance of machine learning, difficult tasks can be completed entirely on their own. In a smart grid (SG), computers and mobile devices may make it easier to control the interior temperature, monitor security, ...
High performance antenna-on-chip inspired by SIW and metasurface technologies for THz band operation
(Nature Research, 2023)
In this paper, a high-performance antenna-on-chip (AoC) is implemented on gallium arsenide (GaAs) wafer based on the substrate integrated waveguide (SIW) and metasurface (MTS) technologies for terahertz band applications. ...
Effective Microorganisms and Glass Nanopowders from Waste Bottle Inclusion on Early Strength and Microstructure Properties of High-Volume Fly-Ash-Based Concrete
(MDPI, 2022)
In concrete production, the use of high-volume fly ash (FA) as the cement substitute became interesting to achieve more sustainable and eco-friendly construction materials. However, concrete produced using high volumes of ...
Optimization of Exploration and Production Sharing Agreements Using the Maxi-Min and Nash Solutions
(MDPI, 2022)
