Risk Based Maintenance in Electricity Network Organisations

Presently, maintenance management of assets in infrastructure utilities such as electricity, gas and water are widely undergoing changes towards new working environments. These are mainly driven against the background of stringent regulatory regimes, an ageing asset base, increased customer demands and constrained financial resources. Therefore,...

Performance-Oriented Fault Tolerance in Computing Systems

In this dissertation we address the overhead reduction of fault tolerance (FT) techniques. Due to technology trends such as decreasing feature sizes and lowering voltage levels, FT is becoming increasingly important in modern computing systems. FT techniques are based on some form of redundancy. It can be space redundancy (additional hardware),...
