State-Of-The-Art Review Of Cathodic Protection For Reinforced Concrete Structures, Aimee Byrne, Niall Holmes, Brian Norton Jan 2016

State-Of-The-Art Review Of Cathodic Protection For Reinforced Concrete Structures, Aimee Byrne, Niall Holmes, Brian Norton

Articles

Cathodic protection (CP) limits the corrosion of a metal surface by making it the cathode of an electrochemical cell. This can be achieved either by using a more active sacrificial anode to create a driving current, or by using inert anodes and impressing a current onto the cathode surface using an external direct current (DC) source. Impressed current cathodic protection (ICCP) is preferred where widespread protection is required, particularly in reinforced concrete structures. ICCP needs a constant DC power supply that is usually provided through a grid connection or independent generators. This paper presents the currently available CP systems for …


An Investigation To Evaluate The Feasibility Of An Intermodal Freight Transport System., Raja Maitra Jan 2016

An Investigation To Evaluate The Feasibility Of An Intermodal Freight Transport System., Raja Maitra

Doctoral

The threat of greenhouse gases and the resulting climate change have been causing concern at international levels. This has led towards new sustainable policies towards reducing the anthropogenic effects on the environment and the population through promoting sustainable solutions for the freight industry. The research was prompted by the growing concerns that were no mode-choice tool to select as an alternative to road freight transport. There were growing concerns that a large percentage of transport related negativities, related various costs and pollution costs, losses arising from traffic accidents, delay costs from congestion and abatement costs due to climate impacts of …


Equity And Fairness In Transport Planning: The State Of Play, Sarah Rock, Aoife Ahern Prof., Brian Caulfield Dr. Jan 2014

Equity And Fairness In Transport Planning: The State Of Play, Sarah Rock, Aoife Ahern Prof., Brian Caulfield Dr.

Conference Papers

This paper explores the concept of equity, or fairness, in transport. As a pillar of sustainable development, social equity is an important objective of transport planning. The provision of transport infrastructure can have significant equity impacts on society through the distribution of costs and benefits. In recent years, there has been an increase in research interest in transportation related equity issues. The paper outlines the primary theoretical traditions that relate to equity and transport equity, and how equity concerns are currently addressed and evaluated in academia and in practice. Recent research has attempted to establish stronger principles from which to …
