For the purpose of improving the redundancy of the auxiliary power supply system of the metro vehicles, the grid connected power supply technology and the high-frequency converter technology were applied to line 4 and line 2 phase II project Covers of the Ningbo metro.4 SIV were grid connected to provide AC 380 V to the metro vehicles which groupin
Visual associations with auditory stimuli have been the subject of numerous studies.Colour, shape, size, and several other parameters have been linked to musical elements like timbre and pitch.In this article, we aim to examine the relationship between harmonisations with varying degrees of dissonance and visual roughness.Based on past research in
In the present work, direct numerical simulation data of a laboratory-scale high Karlovitz number (Ka) jet flame with a strong mean shear and a high Ka freely propagating planar flame without a mean shear were analyzed to explore the influence of flame orientation and mean shear on flame stretch in highly turbulent flames.Three flame fronts, i.e.th
The advantages of coconut coir powder (cocopeat) are resistant to microorganisms, weathering and resistant to mechanical spelling, namely friction and blows.Based on these advantages, cocopeat can be used as a blend of fine aggregates in the manufacture of concrete.The sieve test was conducted on the cocopeat to determine the initial feasibility an
