New design of high-power in-motion inductive charger for low power pulsation
When constructing inductive charging couplers used in stationary charging, design specifications are taken into account that help improve the transfer of optimal power with high efficiency during the distance of an air gap and over a small scale of misalignments. In case of in-motion charging of electric vehicles, the value of the net energy transferred…

A high-efficiency primary-side regulation control strategy for half-bridge LLC resonant converter with wide input voltage range
This chapter will focus on the analysis of the losses of APWFM, as well as a comparative analysis of the losses of FM in the corresponding cases. Turn-ON loss $$ G_{dc\_b} = g_{1} \left( {f_{s} } \right) = \frac{{K\left( {f_{s} /f_{r} } \right)^{2} }}{{\sqrt {\left\{ {\left( {1 + K} \right)\left( {f_{s} /f_{r} } \right)^{2} –…

Research on anti-clogging of ore conveyor belt with static image based on improved Fast-SCNN and U-Net
Dataset production and processing In paper, deep learning image segmentation is used to judge the blockage of the conveyor belt. In the case of no suitable public dataset, we choose to build an ore conveyor belt image segmentation dataset by ourselves. The actual data used in this paper are from a large iron mine located…

Hybrid hemp/glass fiber reinforced high-temperature shape memory photopolymer with mechanical and flame-retardant analysis
Composites design and structural characterizations The fiber volume fraction in FRP polymer composites affects their resultant properties such as strength, stiffness, load transfer efficiency, fracture toughness, thermal expansion, and density43. Although higher fiber volume fractions generally result in improved mechanical properties and dimensional stability, it may proceed in insufficient wettability of the reinforcing fibers by…

Multiband antenna design with enhanced radiations using characteristic mode analysis
In this section, a design procedure based on the superposition of multiple modes at the same resonant frequency is provided, and as design example two antennas are presented. Currents of LOMs are combined with the HODMs to remove the current nulls, and superposition of subsequent radiations to provide enhancement in broadside radiations of the antenna…

A study of thermal performance enhancement of building envelopes by using corncob as construction material
The research background of the material Construction waste comes from the demolished architecture and it should provide positive benefit to it. The use of construction waste as new building material has gained more attention recently. With the acceleration of urbanization, demolition and reconstruction projects generated a large amount of construction waste, which also accelerate the…

Preventing catastrophes with next-generation sensors
As the wind and rain pound the blades of a wind turbine, UBC Okanagan researchers carefully monitor screens, hundreds of kilometres away analyzing if the blade’s coatings can withstand the onslaught. While this was only a test in a lab, the researchers are working to improve the way structures such as turbines, helicopter propellers and…
