To solve the large-scale scheduling problem more efficiently within the requirements of the contract in shipyard, a three-layer parallel computing system was proposed.An optimized model for shipbuilding project scheduling problem was constructed under the condition of taking time and resource constraints into account.Moreover, the key techniques of
This paper reviews the existing studies employing total cost of ownership (TCO) analysis to evaluate the comparative economic viability of battery electric trucks (BETs) and diesel trucks (DTs).A key finding is that until recent years, BETs have not been cost-competitive with DTs.Light-duty trucks and medium-duty trucks started to become competitiv
In this paper, a Multiphysics coupling simulation model of flow and acoustics is proposed using COMSOL software, and its results are verified by comparing with experimental results of others.Then, the aerodynamic pressure above the bluff body surface at a speed of 350 km/h is simulated.Moreover, a near-zero-impedance acoustic metasurface composed o
Abstract To clarify the relationship between earthquake occurrence and fluid, we analyzed data from a dense aftershock-observation network with 69 high-gain short-period seismographs installed immediately after the mainshock occurrence (October 21) in the aftershock area of the 2016 Central Tottori Prefecture earthquake.We determined the hypocenter
