During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice motion is negligible ...
The best smart thermostats we've tested can control your home's heating and cooling with your phone or voice—and might help you save on energy costs. I’ve been working with computers for ages, ...
Abstract: This article proposes a model-free sliding mode control using dynamic gain time delay estimation (DGTDE) to improve the position tracking performance of permanent magnet linear synchronous ...
Figure 1: Principle of light up-conversion and experimental setup. Figure 4: cDNA microarray hybridized with biotinylated cDNA derived from a bladder carcinoma 5637 cell line, visualized using ...
Abstract: The dc-link voltage control is crucial for double-stage solid-state transformers. Due to differences in bandwidth and response speed between the two stages, overvoltage and undervoltage may ...
