Large manufacturers in an industrial park often employ small-batch and high-frequency milk-run logistics (MRL) for materials collection from multiple suppliers. MRL has to be attuned to manufacturers' production progress in a just-in-time (JIT) manner so as to ensure a complete production material supplies required by BOM (bill-of-materials). However, the route planning problem has been regarded as...
Inefficiency of the common lightings like incandescent, fluorescent and halogen lamps presents an ample opportunity to retrofit high efficacy, long life-time and low maintenance LED solid-state lighting, which has significantly reduced in cost on an annual basis. LED lights and many electronic loads used within in-built environment are DC in nature. As such, in this paper, an energy-efficient low...
InAsP/InP(001) quantum dots (QDs) grown by metal organic chemical vapor deposition (MOCVD) are very interesting nanostructures for future applications due to their emission in the C-band telecommunications window. The structural and electronic properties of InAsP/InP(001) quantum dots are investigated by cross-sectional scanning tunneling microscopy and spectroscopy at 77K (X-STM/STS). Spatially and...
The present conditions, causes of sandification and its impacts on the ecological functions of Xianghai wetlands have been studied. Results indicate that human irrational exploitation is the key cause of the sandification of the wetland. The ecological functions of the wetlands, for instance, in flood control, pollution filter, water purification, aquatic productivity, and habitat provision for a...
