Abstract: As engineering change (EC) is an inevitable activity in the industry and uses a lot of engineering design resources, the management of EC has become a crucial discipline. In current researches, most of the data related to ...

Abstract: This paper considers the problem on formation tracking control of second-order multi-agent systems (MASs) with communication time-varying delay. Sufficient conditions on the directed interaction topology and existence of ...

Abstract: A grading curve is an important measure for illustrating the grain size distribution of granular materials. In general, there exists a statistical fractal relationship between the cumulative number of particles and the ...

Abstract: AbstractThe rapid growth of electronic devices has led to significant environmental challenges and resource recovery pressure for discarded printed circuit boards (PCBs). This study reused waste printed circuit board ...
