Feasibility study on lengthening the high-voltage cable section and reducing the number of cable joints via alternative bonding methods [PDF]
, 2019 The mesosphere is perhaps the least explored region in the atmosphere with very few methods of observing. This thesis will primarily be exploring a new technique for measuring the distribution of kinetic energy in the mesosphere across a wide range of ...
