Embedding sustainability in the curriculum; enabling engineering take centre stage

Embedding sustainability in the curriculum; enabling engineering take centre stage
(2009)
Byrne, Edmond P.
Abstract:
Sustainability has been assuming a more central role within chemical engineering curricula and throughout engineering education as a whole. Meanwhile however, engineering has been fighting an uphill battle to attract a consistent proportion of high quality recruits as the profession suffers from a low public profile and uninspiring image. Engineers are generally seen (and see themselves) as uncritical agents of economic and technological development who simply take direction from policy makers and paymasters, albeit ones that provide innovative technical solutions for society. This sells the profession far short and drains from engineering much of the inspiration, excitement and opportunity to “make the world a better place”. Engineering curricula with sustainability embedded as core would however, particularly in the case of chemical engineering, provide a unique opportunity to; - align the curriculum with the policy lead taken by several professional institutions and hence realign...

Teaching engineering ethics and sustainability
(2010)
Byrne, Edmond P.
Abstract:
Most professional engineering code’s of ethics require that engineers shall understand and promote the principles of sustainability and/or sustainable development and have due regard for their environmental, social and economic obligations. However the ethical obligations towards sustainability are incorporated into the teaching of engineering ethics in very few programmes. Typically engineering ethics is taught via relatively straightforward case studies whereby students are asked to identify with a particular individual agent acting alone and determine the correct or optimum course of action. Context, complexity and an interdisciplinary approach tend to lose out to objective reality in such scenarios. This paper describes the teaching of engineering ethics as part of an introductory first year undergraduate module. Students were presented with the real life wicked problem of matching future municipal water supply and demand in Dublin. They were asked to consider the published find...

Electronic engineering education - an Irish perspective
(1991)
Ringwood, John
Abstract:
This paper describes the current approach to electronic engineering education in the School of Electronic Engineering at Dublin City University. Since the first student intake in 1979, the University has developed a range of programs to suit the needs of Irish industry, from the B.Eng degree (with single subject certification) to masters and doctoral programs with research and coursework options. In addition, the School of Electronic Engineering is committed to providing Continuing Engineering Education (CEE) which, for the most part, is integrated with the full time taught courses. Some attention is paid to the industrial training component in the undergraduate program which has been a controversial issue in Irish universities. In addition, the position of graduates within the EC is examined.

ISEE2010
Abstract:
The twenty first century and beyond will present human society with a set of unprecedented challenges emanating from the unsustainable nature of the current societal model. Clearly society must find a transformative model to a sustainable future, and fast. Engineers, with their technical know-how and systems approach to problem solving, are well placed to lead this necessarily multidisciplinary and collaborative endeavour. However, engineering education must provide twenty first century engineers with the necessary tools to undertake the massive challenges ahead. The 3rd International Symposium of Engineering Education took place at University College Cork on 30th June - 2nd July 2010. This significant international conference explored a number of key issues pertaining to engineering education in the twenty first century. These include sustainability in engineering education, IT applications, pedagogical approaches & assessment for learning outcomes, Bologna and industry perspec...

Engineering education for sustainable development: A review of international progress
(2010)
Byrne, Edmond P.; Fitzpatrick, John J.; Hargroves, Karlson; Desha, Cheryl J.
Abstract:
Since the late 1980s there have been increasing calls around the world for embedding sustainability content throughout engineering curricula, particularly over the past decade. However in general there has been little by way of strategic or systematic integration within programs offered by higher education institutions (HEIs). Responding to a growing awareness towards the issues surrounding sustainability, a number of professional engineering institutions (PEIs) internationally have placed increasing emphasis on policies and initiatives relating to the role of engineering in addressing 21st Century challenges. This has resulted in some consideration towards integrating sustainable development into engineering curricula as envisaged by accreditation guidelines. This paper provides a global overview of such accreditation developments, highlighting emerging sustainability competencies (or ‘graduate attributes’) and places these in the context of relevant PEI declarations, initiatives, ...

El-Zouki, Salema
Abstract:
A number of mechanical engineering courses in the British Isles were reviewed and the literature was scanned for the different views and criticism of the available teaching systems. A survey of the opinions of engineers in Ireland about the academic engineering education which they had received was earned out by using a mail questionnaire formulated to obtain information about the industrial training component of the education process and the relevance of the ancillary and basic subjects 425 IEI members returned back the questionnaire, of which 282 member were mechanical engineers, and 70 I Mech E have also responded. This makes up 28% response rate. The respondents were from different age groups, courses backgrounds and occupying different jobs The majority of the respondents were satisfied with the education they received in general and they believe that it helped them in performing current duties. However, a large proportion of the respondents (49%) expressed their views on some ...

Abstract:
THESIS 10424
Project-based design courses are an increasingly conunon component of engineering education. Most engineering schools have traditionally emphasized the analytical and scientific aspects of the discipline, and an increase in practical and experiential learning represents a transformation of established approaches to teaching in these institutions. However, there are significant challenges to developing and delivering these courses. Minimal guidance is available to educators who face these challenges. In particular, there is a paucity of research aligning learning objectives with pedagogical theories and practical guidelines. This thesis makes a contribution to both research and practice in engineering design education. A pedagogical framework for a particular type of project-based engineering design course is developed. The framework is intended to guide the development and evaluation of learning environments for these courses. It consists of learning objectives in t...

Investigating how design concepts evolve in engineering students.
(2016)
Dawidow, John Mark; Huff, James L; Leahy, Keelin
Abstract:
A critical aspect to engineering in the workplace is the ability to design solutions to ill-structured problems. Prior research has shown that such solutions are highly effective when they are evaluated in relation to multiple design concepts. However, a documented problem among engineering students is that they tend to fixate on their initial design ideas rather than branching out and continuing to develop new concepts. In order to address the issue of fixation, 77 Design Heuristics has been established as a method to cultivate ideation among engineers and engineering students. This method for generating design concepts comes in the form of 77 cards, each with a different cognitive prompt for generating a solution (e.g., reduce material, flatten). Through the use of the 77 cards, engineers and engineering students are able to expand their horizons of possible design ideas and develop many unique concepts.Using a freshman engineering course, we integrated the 77 Design Heuristic car...

The Development of a Novel 3D Bioprinting Strategy to Drive Vascularisation, and its Application for Bone Tissue Engineering
(2020)
NULTY, JESSICA
Abstract:
One of the major challenges facing the field of tissue engineering today is vascularisation. Without a system in place to circulate oxygen, nutrients and metabolites, the size of many tissue engineered constructs is restricted, as embedded cells must rely on the diffusion of these factors for their survival. This has limited the clinical translation of engineered tissues and organs. The inclusion of a vascular network within tissue engineered constructs could overcome this constraint, thereby enabling the scaling up of such tissues to previously unattainable, clinically relevant sizes. One branch of tissue engineering which has a considerable need for more effective vascularisation strategies is the field of bone tissue engineering. Bone tissue engineering endeavours to produce bone substitutes and provide a viable alternative to autologous bone grafts. To achieve this, new approaches to produce large, viable bone tissues must be identified. The overall aim of this thesis was to dev...

Practical skills and techniques for the transition to a sustainable future, a case study for engineering education
(2010)
Dwyer, Brian; Byrne, Edmond P.
Abstract:
This paper seeks to assess the gap between the visions of sustainable engineering practice with its current reality. A case study involving Energetics Pty. Ltd., a leading Australian multi-disciplinary consultancy specialized in engaging public and private organizations in the development of their responses to climate change and sustainability was conducted based on a staff questionnaire developed following a review of current literature and initiatives on sustainability globally. The results of the survey indicate that sustainability in engineering practice is still focused on the technical and financial impacts of perceived sustainable solutions. The broader aspects that have been identified as necessary have yet to be achieved in education or practice. The principle reason for this appears to lie in the perception engineers have of their practice and the ability of engineers to communicate effectively with their clients. These have combined to make regulation one of the principal...

Abstract:
THESIS 8757
Tissue engineering (or regenerative medicine) is defined as the application of scientific principles to the synthesis of living tissues using bioreactors, cells, scaffolds, growth factors, or a combination (Rose and Oreffo, 2002). One of the principal methods in tissue engineering involves the use of a porous scaffold to support and guide synthesis of a 3D tissue or organ (Sachlos and Czernuszka, 2003). Collagen-Glycosaminoglycan scaffolds have found success in several clinical applications of tissue engineering (Yannas et al., 1989, Chamberlain et al., 1998).

An optimized surface topography for calcium phosphate bone tissue engineering scaffolds
(2016)
Mealy, Jacob Sebastian
Abstract:
THESIS 11040
Improved scaffold/host integration and avoiding core necrosis are important and active goals in tissue engineering. Alternatives to bone tissue grafting that are highly bioactive and inexpensive to manufacture are clinical necessities, particularly in relation to today?s ageing population profiles. There is also a need to develop such grafting alternatives for applications where tissue-engineered solutions (i.e. based on tissue growth in perfusion bioreactors) are not feasible from a clinical and cost perspective. Nanoscale surface topography has the potential to influence many aspects of cellular behaviour on tissue engineering scaffolds including proliferation. The aim of this project was to optimize the surface topography of a hydroxyapatite (HA) bone tissue engineering scaffold in order to increase mesenchymal stem cell (MSC) proliferation on the construct. The working hypothesis was that nanoscale features incorporated into the scaffold pore surfaces would prov...

A traffic engineering system for DiffServ/MPLS networks
(2003)
Chpenst, Alexei
Abstract:
This thesis presents an approach to traffic engineering that uses DiffServ and MPLS technologies to provide QoS guarantees over an IP network. The specific problem described here is how best to route traffic within the network such that the demands can be carried with the requisite QoS while balancing the load on the network. A traffic engineering algorithm that determines QoS guaranteed label-switched paths (LSPs) between specified ingress-egress pairs is proposed and a system that uses such an algorithm is outlined. The algorithm generates a solution for the QoS routing problem of finding a path with a number of constraints (delay, jitter, loss) while trying to make best of resource utilisation. The key component of the system is a central resource manager responsible for monitoring and managing resources within the network and making all decisions to route traffic according to QoS requirements. The algorithm for determining QoS-constrained routes is based on the notion of effecti...

Nahari, Noha
Abstract:
This thesis reports on a study investigating the mathematical skills and attitudes of incoming engineering students in Dublin City University. The following questions are posed in this thesis: What are the students' strengths and weaknesses in basic areas of mathematics? What beliefs do the students express in relation to mathematics? The research attempted to answer these questions using two approaches: Firstly, an attitudinal survey was undertaken to identify students' attitudes towards mathematics, under a selection of different headings. Secondly, mathematics tests were run, focusing on the core mathematical skills necessary for engineering students. Both the test and survey were run at the beginning and/or end of the academic years 2012/2013 and 2013/2014 to give comparative data. The results of the survey reflected high levels of confidence in relation to mathematics and high goals in relation to mathematical achievement. The test results showed a number of strengt...

Towards engineering whole bones through endochondral ossification

Abstract:
THESIS 10341
A number of clinical situations exist where bone regeneration is required in large quantities, such as for the treatment of critical size bone defects and for the replacement of whole bones lost due to trauma or disease. The current ?gold standard? treatment is implantation with an autologous bone graft, harvested from the patient?s own body. Drawbacks of this approach include donor site morbidity, and a limitation on the quantity of tissue available for harvest, which have motivated the search for alternative novel strategies, aimed at bone regeneration. The field of tissue engineering aims to regenerate or replace damaged tissues through a combination of cells, three-dimensional scaffolds and signalling molecules. To date, bone tissue engineering applications have generally focussed on the direct osteogenic priming of mesenchymal stem cell (MSC) seeded scaffolds in a process resembling intramembranous ossification. Limitations associated with the traditional intra...

Abstract:
The repair of osteochondral defects, affecting both the articular cartilage and the underlying subchondral bone, is key for the effective recovery of joint homeostasis and the prevention of further cartilage degeneration and the onset of osteoarthritis (OA). Although important advances have been made in the field of tissue engineering to regenerate these injuries, the traditional approaches based on the formation of homogenous tissues fail to recapitulate the spatial complexity of the osteochondral unit. The objective of this thesis was to engineer a multiphasic tissue suitable for osteochondral defect regeneration by combining 3D bioprinting and non-viral gene delivery to spatially regulate the differentiation of mesenchymal stem cells (MSCs). Realising this objective first required (1) optimisation of the non-viral gene delivery vector, (2) the identification of suitable therapeutic gene combinations to direct MSC differentiation and (3) the development of printable biomaterials,...

Spatial presentation of tissue specific extracellular matrix components and growth factors on porous electrospun fibre scaffolds for bone-ligament interface tissue engineering

Abstract:
In many clinical situations ligament or tendon replacements are required, such as for the surgical replacement of a torn anterior cruciate ligament (ACL). The current ?gold standard? treatment is resection of the torn ligament and replacement by an autologous tendon graft. Limitations of this approach include that the interface between the tendon graft and the bone heals as a loose fibrovascular tissue instead of a resilient fibrocartilage enthesis, which leads to long term mechanical instability of the replacement graft. This has motivated the search for alternative strategies to regenerate damaged ligaments. The field of tissue engineering (TE) aims to regenerate or replace damaged tissues through a combination of three-dimensional (3D) scaffolds, cells and signalling molecules. This thesis aims to develop a mechanically functional scaffold that provides spatially defined regulatory cues for ligament TE, with the specific goal of regenerating the stratified interface between lig...

Abstract:
THESIS 5332
Prediction of fatigue failure in engineering artefects is becoming increasingly important as we enter the third millennium; more catastrophic fatigue failures will occur as engineers push the limits of design even further due to demands for greater efficiency. This thesis describes a methodology for predicting fatigue failure in engineering components subjected to high cycle fatigue using the finite element analysis method.

The application of genetic algorithms to civil engineering optimisation problems
(2001)
O'Dwyer, Dermot W.
Abstract:
THESIS 6283
Genetic algorithms are optimisation algorithms that mimic the mechanisms of natural selection. This thesis is concerned with the theoretical development of genetic algorithms and with their successful application to civil engineering optimisation problems. This thesis can be subdivided into two sections. The first deals with the theoretical behaviour of genetic algorithms and the second deals with their application to civil engineering optimisation. The existing basis of the genetic algorithm rests on the schema theorem and the building-block hypothesis. Theoretical work presented in this thesis develops the schema theorem to include the effects of crossover and proves the building-block hypothesis. The new theoretical work presented on the schema theorem is related to existing fundamental theory in the field of population genetics.

Composite scaffold development and bioreactor culture for bone tissue engineering
(2009)
Plunkett, Niamh
Abstract:
THESIS 9254
Bone tissue engineering involves seeding bone cells onto a scaffold, culturing this construct so that mineralisation occurs (by using signalling mechanisms such as growth factors or bioreactors) and then implanting it into a defect site in the body. This is called the tissue engineering triad: combining cells, scaffold and signalling to engineer tissue in vitro. In this work, the focus was on two aspects of the triad: scaffold development and signalling using a bioreactor. The general aim in this work was to develop a tissue engineered construct with enhanced osteogenic capabilities due to its structural and material properties, populated by a homogeneous distribution of stimulated cells.

Remote access to continuing engineering education - RACeE
(1997)
Whelan, Paul F.
Abstract:
This paper discusses the issues involved with the development and implementation of an on-line postgraduate course for remote-access students. This is especially relevant for students who wish to pursue postgraduate qualifications, or to update their skill base, while continuing with their career. Although remote-access education would not be considered by the author as the delivery method of choice for the majority of an engineering student's educational needs, there will always be niche educational demands that can be addressed by such an approach. Although the electronic presentation of course notes via the Internet is becoming more commonplace, the ideas outlined in this paper go beyond this basic concept. The emphasis of any remote-access-based educational strategy has to be on the interaction between the tutor and the students, and not on note presentation.

A software process engineering approach to understanding software productivity and team personality characteristics: an empirical investigation
(2013)
Yilmaz, Murat
Abstract:
Despite the significant effort in managing the complexities of software development by using several engineering analogies, there is still no comprehensive approach that recognizes software development as a social activity and software productivity in form of an intangible asset gained and maintained by social relations. This study proposes a model in which software productivity improvement is investigated as a function of the factors affecting productivity, whereas team productivity is considered as a compatibility problem of distinct personality traits that should be situated in an efficient social configuration. The fundamental assumption is that the productivity is a latent construct measurable by a set of indicators and improvable by relating personality traits and team configurations. The two main contribution of this thesis is to develop an understanding of the factors affecting software productivity by empirical investigation and to build a personality-profiling test based ...

Aspects of parallel processing and control engineering
(1991)
McKittrick, Brendan J
Abstract:
The concept of parallel processing is not a new one, but the application of it to control engineering tasks is a relatively recent development, made possible by contemporary hardware and software innovation. It has long been accepted that, if properly orchestrated several processors/CPUs when combined can form a powerful processing entity. What prevented this from being implemented in commercial systems was the adequacy of the microprocessor for most tasks and hence the expense of a multi-processor system was not justified. With the advent of high demand systems, such as highly fault tolerant flight controllers and fast robotic controllers, parallel processing became a viable option. Nonetheless, the software interfacing of control laws onto parallel systems has remained somewhat of an impasse. There are no software compilers at present which allow a programmer to specify a control law in pure mathematical terminology and then decompose it into a flow diagram of concurrent processe...
