Abstract The effect of fluid flow on crystal nucleation in supercooled liquids is not well understood. variable density and temperature gradients the liquid make it difficult to study this under terrestrial gravity conditions. Nucleation experiments were therefore made a microgravity environment using Electromagnetic Levitation Facility International Space Station bulk glass-forming Zr 57 Cu 15...

Diode-rectifier-based high voltage dc (DR-HVdc) systems can be a promising low-cost solution for exporting wind power from remote offshore farms to onshore systems. Industrializing the DR-HVdc requires technical maturation, achievable through in-depth studies and pilot experiments. Deployment of may entail fundamental change control philosophy in turbine (WT) converters grid-following grid-form...

In this work, cold bulge forming of an Aluminium-Magnesium (Al-Mg) sheet with a solid bulging medium is performed experimentally and numerically.  Mechanical properties and thickness variations of Al-Mg sheet are evaluated before and after the forming process.  The results indicated that the Al-Mg sheet has taken the desired shape without necking using the cold bulge forming process.  Also, the...

Background and objectives: Electric, magnetic and electromagnetic fields can act as stress factors with different effects on biological systems. Due to the nutritional and medicinal values, and the increasing electromagnetic radiations, the present study was performed to investigate the effects of the electromagnetic field on the developmental stages and cytotoxic properties of...

High power ultra wideband (UWB) systems can be used for various applications like buried target detection, electrical characterization of materials, space debris detection and as a source for vulnerability studies on electronic circuits. Two high power UWB radiator systems have been developed at APPD, BARC Mumbai. The first one is a 120 kV, 66 Ohm system which uses balanced Transverse Electroma...
