We present the development of a new algorithm which combines state-of-the-art energy-dispersive x-ray (EDX) spectroscopy theory and a suitable machine learning formulation for the hyperspectral unmixing of scanning transmission electron microscope EDX spectrum images.The algorithm is based on non-negative matrix factorization (NMF) incorporating ar
Wire and arc additive manufacturing has unique process characteristics, which make it have great potential in many fields, but the large amount of heat input brought by this feature limits its practical Bag application.The influence of heat input on the performance of parts has been extensively studied, but the quantitative description of the influ
This research implements a recent evolutionary-based algorithm of equilibrium optimizer to resolve the constrained combined economic emission dispatch problem.This problem has two objective functions that represent the minimizing of generation costs and minimizing the emission of environmental pollution caused by generators.The proposed algorithm i
During nightly foraging activity, echolocating bats drink by flying low over the water surface and dipping the lower jaw while avoiding further bodily contact with the water.This task poses different sensorimotor challenges than flying in the open to forage for insects.Of interest is how bats adjust the timing of their echolocation pulses to accomm
To facilitate through operation on railway lines with different gauges, this paper presents the design of a gauge-changeable locomotive bogie along with wheelsets that are adaptable to gauge changes between 1 000 mm and 1 435 mm.Based on a wheel-locking mode that was selected after analyzing various locking and unlocking methods, the overall bogie
