Masters

Ireland is changing and this change is nowhere more apparent than in the rapidly growing construction industry. The industry is being forced to change at an unprecedented pace. This thesis sets out to develop a framework on which construction organisations can approach and manage change.

It examines the issues that will cause change, reviews the available literature to find how change can be managed and controlled, and develops a model for guiding change programmes in the construction industry. The model is tested against three case studies, the first two of which are concerned with finding increases in efficiency and demonstrating …

Application Of Pvd Coatings To Enhance The Wear Life Of Needles Used In The Textile Industry, Neil Donnelly

Masters

Needles are used in the textile industry for weaving. In high volume textile production a problem is wear of the needle eyelet as the threat is pulled through. This wear results in a cost to the textile manufacturer both in needle replacement, but in many cases more importantly, lost production during needle substitution The objective of this study was to examine the potential of wear resistant coatings deposited using the magnetron sputtering technique to increase the life-time of textile needles. Four coatings were evaluated, titanium nitride, titanium carbonitride, titanium diamond-like carbon and a novel coating titanium nitride/molybdenum disulphide. These coatings …
