Causality Analysis for COVID-19 among Countries Using Effective Transfer Entropy
(MDPI, 2022)
In this study, causalities of COVID-19 across a group of seventy countries are analyzed with effective transfer entropy. To reveal the causalities, a weighted directed network is constructed. In this network, the weights ...
Enhanced Sensing Capacity of Terahertz Triple-Band Metamaterials Absorber Based on Pythagorean Fractal Geometry
(MDPI, 2022)
A new design of a triple band perfect metamaterial absorber based on Pythagorean fractal geometry is proposed and analyzed for terahertz sensing applications. The proposed design showed an enhanced sensing performance and ...
Analysis of various flow field designs for PEM fuel cells used in vehicular systems through 3D modelling
