Tilted-Beam Antenna Based on SSPPs-TL with Stable Gain

open access: yesSensors, 2021
In this paper, a titled-beam antenna based on spoof surface plasmon polaritons (SSPPs) transmission lines (TLs) is proposed. The parallel SSPPs-TL is a slow-wave TL, which is able to limit waves in the TL strictly.

Estimating Solar Irradiance on Tilted Surface with Arbitrary Orientations and Tilt Angles [PDF]

open access: yesEnergies, 2019
Photovoltaics modules are usually installed with a tilt angle to improve performance and to avoid water or dust accumulation. However, measured irradiance data on inclined surfaces are rarely available, since installing pyranometers with various tilt angles induces high costs.

Matrix-Tilted Archimedean Copulas [PDF]

open access: yes, 2021
The new class of matrix-tilted Archimedean copulas is introduced. It combines properties of Archimedean and elliptical copulas by introducing a tilting matrix in the stochastic representation of Archimedean copulas, similar to the Cholesky factor for ...

Physical model experiment on failure mechanism and NPR anchor cable control effect of layered counter-tilted slope

open access: yesRock and Soil Mechanics, 2021
Taking the large-scale toppling failure counter-tilted slope in Changshanhao open-pit mine in Inner Mongolia as engineering background, a layered counter-tilted slope geological generalized physical model was constructed based on similar theory. Physical
