A series of equivalent area circle yield criteria based on unified strength theory [PDF]

open access: yesE3S Web of Conferences, 2021
Unified strength theory considering the influence of the intermediate principal stress is widely used in geotechnical engineering, but the singularities bring inconvenience to the numerical calculation.

Effects of GaN Buffer Resistance on the Device Performances of AlGaN/GaN HEMTs

open access: yesCrystals, 2020
We investigated the effects of GaN buffer resistance of AlGaN/GaN high-electron-mobility transistors (HEMTs) on direct current (DC), low-frequency noise (LFN), and pulsed I-V characterization performances.

Low-Frequency Noise Behavior of AlGaN/GaN HEMTs with Different Al Compositions

open access: yesCrystals, 2020
AlxGa1−xN/GaN heterostructures with two kinds of Al composition were grown by metal organic chemical vapor deposition (MOCVD) on sapphire substrates. The Al compositions in the AlGaN barrier layer were confirmed to be 13% and 28% using high resolution X ...

Periodic orbits for space-based reflectors in the circular restricted three-body problem [PDF]

open access: yes, 2016
The use of space-based orbital reflectors to increase the total insolation of the Earth has been considered with potential applications in night-side illumination, electric power generation and climate engineering. Previous studies have demonstrated that

Comparison of the elastic limit and yield load of nailed joints connecting solid wood and wood-based board material

open access: yesJournal of Wood Science, 2022
Evaluations of the lateral properties of timber joints are necessary to ensure the safety of timber buildings. The yield load is an important property that is usually obtained using authorized engineering techniques. Although yield loads have been easily

Airborne electromagnetic sea ice thickness sounding in shallow, brackish water environments of the Caspian and Baltic Seas [PDF]

open access: yes, 2006
Ice engineering projects often rely on the knowledge of ice thickness in shallow, brackish water like in the Baltic and Caspian Seas. By means of field data and model results, the paper shows that helicopter-borne electromagnetic induction measurements ...

Photosynthetic antenna engineering to improve crop yields

open access: yesPlanta, 2017
Evidence shows that decreasing the light-harvesting antenna size of the photosystems in tobacco helps to increase the photosynthetic productivity and plant canopy biomass accumulation under high-density cultivation conditions. Decreasing, or truncating, the chlorophyll antenna size of the photosystems can theoretically improve photosynthetic solar ...
