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 ...

Further Investigations into the Capacitive Imaging Technique Using a Multi-Electrode Sensor
Applied Sciences, 2018 As a novel non-destructive testing technique, capacitive imaging (CI) has been used to detect defects within the insulation layer and metal surface of an insulated metallic structure, that is, pipe or vessel. Due to the non-linearity of the probing field,
