Increasingly, industrial operations adjoin residential communities. As the demand for natural resources increases, this problem is only more likely to exacerbate in coming decades. Thus, it is imperative to fully understand ...
This paper describes how pure
travelling waves in cascaded, lumped, uniform, mass-spring systems can be
defined, established, and maintained, by controlling two boundary actuators,
one at each end. In most cases the ...
This paper shows how pure travelling waves in cascaded, lumped, uniform, mass-spring systems can be defined, established, and maintained, by controlling two boundary actuators, one at each end. In most cases the control ...
An objective of the European Commission 5th Framework Research project, Samaris, is to determine the bridge repair needs of new and possible future member states of the European Union (EU). This paper reports the findings ...
The concept of a road roughness index for bridge dynamics is developed. The International Roughness Index (IRI) is shown to be very poorly correlated with bridge dynamic amplification as it takes no account of the location ...
Building reuse is a linchpin to managing solid waste. Despite the various benefits beyond contributing to sustainability that can be realized through building reuse, including direct and indirect cost savings, truncated ...
This paper examines peat power production in Ireland under the three pillars of energy policy—security, competitiveness and environment. Peat contributes to energy security—as an indigenous fuel, it reduces dependency on ...
The response of a bridge to a pre-weighed truck can be
measured on site. This paper describes a mathematical
method for converting the measured response of a load
effect into an influence line for that effect. One ...
This paper describes the use of project-based learning to teach design skills to civil engineering students at University College Dublin (UCD). The paper first considers the development of problem-based leaning (PBL) as a ...
This paper describes 2 case studies where problem based learning has been introduced to undergraduate civil engineering students in University College Dublin. Problem based learning has recently been put in place in the ...
A signal may have compact support, be band-limited (i.e., its Fourier transform has compact support), or neither (“unbounded”). We determine conditions for the linear canonical transform of a signal having these
properties. ...
Laboratory testing for foundation design offers advantages over field-testing, especially, where existing installations preclude easy accessibility. Advantages include a homogeneous soil, ability to place instrumentation ...
Aims: The purpose of this study was to develop a system that would allow biofilms to be cultivated under strictly defined conditions in terms of dissolved oxygen, fluid shear and to assess whether the method was suitable ...
A database of research quality CPTU and shear wave velocity
information for Norwegian marine clays has been assembled so as to study the small
strain stiffness relationships for these materials and to examine the potential ...
Pavement surface profiles induce dynamic ride responses in vehicles which can potentially be used to classify road surface roughness. A novel method is proposed for the characterisation of pavement roughness through an ...
In today’s society there is a vast and in many cases not fully appreciated dependence on electrical power for everyday life. Furthermore, with growing energy and environmental concerns arising due to fossil fuel depletion ...
More accurate assessment of safety can prevent unnecessary repair or replacement of existing bridges which in turn can result in great cost savings at network level. The allowance for dynamics is a significant component ...
When formulating an approach to assess bridge traffic loading with allowance for Vehicle-Bridge Interaction (VBI), a trade-off is necessary between the limited accuracy and computational demands of numerical models and the ...
The adsorption characteristics of phosphate adsorption on the dewatered alum sludge were identified as a function of pH and ion strengths in solution. In addition, adsorption mechanisms were investigated by conducting batch ...
In recent years highway bridge load assessment has been recognised as an area through which savings can be made by avoiding unnecessary bridge refurbishment and replacement. Load effects in bridges result from single truck ...
