The influence of concrete mix composition and environmental exposure on long-term chloride ingress in concrete
… Africa were investigated, aiming at improving service life prediction models for reinforced concrete structures situated in marine exposure classes. Time-dependent chloride ingress was measured over a period of roughly 4 years with respect to the influences of binder type, w/b ratio and …

Service quality management in conference tourism : expectations versus delivery
… primary objective of this study was to determine service expectations of conference delegates in relation to the service delivered at Quest Conference Estate. This objective was achieved by firstly analysing service quality in terms of the expectation of service delivery prior to attending a …

An investigation into consulting engineering service quality perceptions and expectations
This thesis focuses on the 'Quality of Service' provided by Consulting Civil/Structural engineers. The study assesses whether or not there are shortfalls in the quality of engineering services provided by consulting engineers. It identifies service dimensions that are problematic and also …

A New Approach to Assessment and Utilisation of Distribution Power Transformers
… quality of supply and improvements of customer services. These, sometimes conflicting requirements have forced the electrical distribution utilities to move focus from improving economic efficiency of electricity supply and abandon long established practices for evaluation of distribution system …

Essays on the industrial organization of the airline industry
… The degree to which prices respond to changes in service quality should depend on consumers' willingness-to-pay for quality, as well as the availability of substitute products. I study the effect of an exogenous variation in on-time arrivals, as one dimension of service quality in the airline …

Risk-based facility management approach for building components using a discrete Markov process - predicting condition, reliability, and remaining service life
… it supports an unbiased process of determining expected service life for components by using the Markov chain model to compute the average number of time cycles to reach the failure state. This probabilistic Markov chain prediction model provides a foundation towards a risk-based framework for …
