A bit (binary digit) is the smallest unit of information • N = 2n where N is the number of representations and n is the number of bits (ex. ASCII, Unicode, PCM code etc.) • Data communications transfer information using codes that are transmitted as signals (either analog or digital) • In general, analog lines provide a slow service that contains high error rates.

In this thesis, the rolling contact wear of 52100 bearing steel and Over-aged Magnesia-Partially-Stabilised Zirconia (OA-Mg-PSZ) ceramic are examined using a newly developed rolling contact wear test rig. The new wear test rig simulates the system geometry of an un-lubricated hybrid (ceramic and steel) ball bearing. The new wear test rig is versatile in that it allows low cost samples to be utilised resulting in a larger number of samples that can be tested.

Objective: Objective of this dissertation is to find a novel method to reduce computation cost as well as memory requirement but still retain accuracy in video-based person ReID approach. In video-based person ReID, computation cost and memory requirement are the two main issues. Working with a large number of images is the burden of any surveillance system. This results in a high computation cost as well as a large memory capacity.
