Agv Controlled Fms, Fergus G. Maughan Nov 2015

Agv Controlled Fms, Fergus G. Maughan

The ITB Journal

One of the key factors that prevent the implementation of Flexible Manufacturing Systems (FMS) is the elaborate cost associated with the control software. In a FMS there is often a wide range of equipment such as personal computers Programmable Logical Controllers (PLCs), CNC Machines or robots, each of these having their own “intelligence” and library of data. Providing a means of communication between these individual controllers has traditionally been achieved using a Local Area Network (LAN). This proves more expensive when traditional manual operated machines have to be integrated into the system. The model described in this paper provides an …


Fuzzy Logic And Neural Networks - A Glimpse Of The Future, Raymond Manley Nov 2015

Fuzzy Logic And Neural Networks - A Glimpse Of The Future, Raymond Manley

The ITB Journal

In 1965 Lofti Zadeh published his paper on fuzzy set theory , putting it forward as a way of more closely realising the human thought process. Many systems developed to aid human activities have been based on definitive , yes/no, type decision making processes. An example is the way all computers are based on the binary logic system where only two possible and separate logic levels are allowed, a logic 1 or logic 0. However, we know from everyday experience that humans think in terms of vague linguistic categories, for example, the weather is fairly good today. "Fairly good" represents …

Weighting The Perceived Importance Of Minimising Economic, Social, And Environmental/Cultural Risks In Flood Risk Management, Zeinab Bedri, John O'Sullivan

Reports

A new national flood policy adopted in Ireland in 2004 set out that a range of flood-related impacts should be taken into account in planning flood risk management strategies and projects, including impacts on people, properties, the environment and cultural heritage. This was reinforced by the 2007 EU 'Floods' Directive that is aimed at the reduction of adverse consequences of flooding for human health, the environment, cultural heritage and economic activity.

In 2006, the Office of Public Works (OPW) began the National Catchment-based Flood Risk Assessment and Management (CFRAM) Programme through a series of pilot studies. A Multi-Criteria Analysis (MCA) …


An Exploration Of The Effects Of Enhanced Compiler Error Messages For Computer Programming Novices, Brett A. Becker Nov 2015

An Exploration Of The Effects Of Enhanced Compiler Error Messages For Computer Programming Novices, Brett A. Becker

Theses

Computer programming is an essential skill that all computing students must master and is increasingly important in many diverse disciplines. It is also difficult to learn. One of the many challenges novice programmers face from the start are notoriously cryptic compiler error messages. These report details on errors made by students and are essential as the primary source of information used to rectify those errors. However these difficult to understand messages are often a barrier to progress and a source of discouragement. A high number of student errors, and in particular a high frequency of repeated errors – when a …

Cultural Change Through Bim: Driving Lean Transformation In Education, Avril Behan, Malachy Mathews, Kevin Furlong, Ciara Ahern, Una Beagon, Peter Brennan, Colin Conway, Lee Corcoran, Pierce Fahy, Alan Hore, Barry Mcauley, Trevor Woods

Conference papers

This paper presents a case study of how the adoption of BIM-based practices in the AECO industry is being reflected by cultural change in higher education in Ireland. The silo-mentality that has dominated the AECO sector for more than a century has, despite numerous reorganisations, been replicated in the structures of educational institutions, including in Technological University Dublin since the inception of its founding colleges in the late 1800s. Most AECO programmes must include content that is external to the programme’s specific discipline. Through the School structures of the Institute, delivery of such content is known as "service teaching" and …


Design Science: Choosing An Appropriate Methodology For Research In Bim, Dermot Kehily, Jason Underwood Nov 2015

Design Science: Choosing An Appropriate Methodology For Research In Bim, Dermot Kehily, Jason Underwood

Conference papers

This paper discusses Building Information Modelling (BIM) in relation to proposing design science as a methodology for BIM research. The paper firstly outlines how BIM is changing construction work practices to a more collaborative and integrated set of procedures, facilitated through the application of modelling technologies. The use of traditional research methods for BIM research in the context of developing and subsequently evaluating a BIM process or technology is then questioned. The premise of this rationale is that BIM revolves around new practices and emerging technologies that propose to provide efficiency in delivering constructed assets in the built environment. Traditional …

Is This "Transfer Shock"? Examining The Perceptions Of Engineering Students Who Articulate Within The Irish Higher Education Context., Susan O'Shaughnessy, Anne Marie Mccarrick, Fionnuala Farrell, Una Beagon, Lance C. Perez Oct 2015

Is This "Transfer Shock"? Examining The Perceptions Of Engineering Students Who Articulate Within The Irish Higher Education Context., Susan O'Shaughnessy, Anne Marie Mccarrick, Fionnuala Farrell, Una Beagon, Lance C. Perez

Conference papers

Abstract—“Transfer shock” is a well-known phenomenon during the process of articulation, when students move from short-cycle applied programs to more academic longer-cycle study programs. In the US context this problematic transition has been observed in students transferring from community colleges into the traditional university system. In Ireland’s binary higher education structure, one set of institutions, known as Institutes of Technology (IoTs) allow for this transition to take place entirely within individual institutions. This paper is part of an ongoing investigation into one such IoT, where engineering students who achieve high grades at the end of 3-year (so-called Level 7) “ordinary …

Determination Of The Polymerisation Rate Of A Low-Toxicity Diacetone Acrylamide-Based Holographic Photopolymer Using Raman Spectroscopy, Dervil Cody, Emilia Mihaylova, Luke O'Neill, Izabela Naydenova Oct 2015

Determination Of The Polymerisation Rate Of A Low-Toxicity Diacetone Acrylamide-Based Holographic Photopolymer Using Raman Spectroscopy, Dervil Cody, Emilia Mihaylova, Luke O'Neill, Izabela Naydenova

Articles

The polymerisation rate of a low-toxicity Diacetone Acrylamide (DA)-based photopolymer has been measured for the first time using Raman spectroscopy. A value for the polymerisation rate of 0.020 s−1 has been obtained for the DA photopolymer by modelling the polymerisation reaction dynamics as a stretched exponential or Kohlrausch decay function. This is significantly lower than the polymerisation rate of 0.100 s−1 measured for the well known Acrylamide (AA)-based photopolymer composition. The effect of the additive glycerol on the polymerisation rate of the DA-based photopolymer has also been investigated. The inclusion of glycerol is observed to increase the rate …

An Exploration Of The Use Of Gamification In Agile Software Development, Alan Mcclean Sep 2015

An Exploration Of The Use Of Gamification In Agile Software Development, Alan Mcclean

Dissertations

Although Project Management has existed for many millennia, software project management is relatively new. As a discipline, software project management is considered difficult. The reasons for this include that software development is non-deterministic; opaque and delivered under ever-increasing time pressure in a volatile environment. Evolving from Incremental and Iterative Development (IID), Agile methodologies have attempted to address these issues by focusing on frequent delivery; working closely with the customer; being responsive to change and preferring working software to extensive documentation. This focus on delivery rather than documentation has sometimes been misrepresented as no documentation, which has led to a shortfall …

An Evaluation Of Selection Strategies For Active Learning With Regression, Jack O'Neill Sep 2015

An Evaluation Of Selection Strategies For Active Learning With Regression, Jack O'Neill

Dissertations

While active learning for classification problems has received considerable attention in recent years, studies on problems of regression are rare. This paper provides a systematic review of the most commonly used selection strategies for active learning within the context of linear regression. The recently developed Exploration Guided Active Learning (EGAL) algorithm, previously deployed within a classification context, is explored as a selection strategy for regression problems. Active learning is demonstrated to significantly improve the learning rate of linear regression models. Experimental results show that a purely diversity-based approach to


Thermodynamic Analysis Of Closed Steady Or Cyclic Systems, Jim A. Mcgovern Sep 2015

Thermodynamic Analysis Of Closed Steady Or Cyclic Systems, Jim A. Mcgovern

Articles

Closed, steady or cyclic thermodynamic systems, which have temperature variations over their boundaries, can represent an extremely large range of plants, devices or natural objects, such as combined heating, cooling and power plants, computers and data centres, and planets. Energy transfer rates can occur across the boundary, which are characterized as heat or work. We focus on the finite time thermodynamics aspects, on energy-based performance parameters, on rational efficiency and on the environmental reference temperature. To do this, we examine the net work rate of a closed, steady or cyclic system bounded by thermal resistances linked to isothermal reservoirs in …
