Role of tidal range and coastline morphology on the evolution of two macrotidal sand spits
The Depositional Record, Volume 11, Issue 1, Page 311-327, February 2025.Based on historical map and stratigraphic data, the construction dynamics of two sandspits, respectively, subject to macrotidal and hypertidal range (6.5 m vs. 14 m), and that both appeared at the end of the 17th century, are compared. The hypertidal spit developed fast, between 1650 and 1750 CE, with a dominant seaward direction while the macrotidal ...

Electrohydraulic effect of microsecond pulsed discharge in transformer oils
High Voltage, Volume 10, Issue 1, Page 137-145, February 2025.Abstract The physical process of microsecond pulsed discharge in transformer oil is the foundation for studying the initial mechanics of faults in ultra‐high voltage transformers. However, the microsecond‐scale electrohydraulic effect in transformer oil has not been investigated yet.

Effect of Root Opening on Distortion of Butt-Joints in Submerged Arc Welding [PDF]
, 2016 The dimensional differences in steel bridge manufacturing caused by weld deformation often occur for butt joints of thin plates. The problems of distortion, residual stresses and reduced strength of structure in and around a welded joint are of major ...

Optimal control of the heave motion of marine cable subsea-unit systems [PDF]
, 1995 One of the key problems associated with subsea operations involving tethered subsea units is the motions of support vessels on the ocean surface which can be transmitted to the subsea unit through the cable and increase the tension.

Researches on Submerged Arc Welding
Journal of the Japan Welding Society, 1950 In order to find out a good flux for submerged arc welding, various expeniments were executed, and following results are obtained.(1) For the welding, the most suitable melting point of the flux was about 1, 350°C and the specific gravity was 4.5.(2) According to the result of the mechanical tests, the flux is applicable to practice.(3) The welding ...
