Drum Transcription using Automatic Grouping of Events and Prior Subspace Analysis
(2003)
Fitzgerald, Derry; Lawlor, Bob; Coyle, Eugene
Abstract:
While Prior Subspace Analysis (PSA) has proved an effective tool for transcribing mixtures of snare, kick drum and hi-hat both in the "drum-only" case and in the presence of pitched instruments attempts to extend it to deal with increased numbers of drum types have met with mixed results.To overcome this an automatic modeling and grouping procedure has been developed which groups drum events on the similarity of their frequency content. Combining this procedure with PSA allows the extension of PSA to robustly handle greater numbers of drum types. The effectiveness of this approach is demonstrated in a drum transcription algorithm.

E-Fraud Prevention based on the Self-Authentication of E-Documents
(2010)
Blackledge, Jonathan; Coyle, Eugene
Abstract:
We consider a method for preventing e-Fraud in which a binary image is encrypted with a floating point cipher using a convolution operation and the output quantized into a 1-bit array generating a binary image ciphertext. The output is then ‘embedded’ in a host image to hide the encrypted information. Embedding is undertaken either in the lowest 1-bit layer or multiple 1-bit layers. Decryption is accomplished by: (i) extracting the binary image from the host image; (ii) correlating the result with the original cipher. In principle, any cipher generator can be used for this purpose and the method has been designed to operate with 24-bit colour images. The approach has a variety of applications and in this paper, we focus on the authentication and self-authentication of e-documents (letters and certificates, for example) that are communicated over the Internet and are thereby vulnerable to e-Fraud (e.g. modification, editing, counterfeiting etc.).

Educating Engineers for the 21st. Century: and why some Elements of History and Philosophy should be Incorporated into the Curriculum
(2007)
Grimson, William; Murphy, Mike; Coyle, Eugene
Abstract:
It has been said that in some respects the Russian composer Igor Stravinsky was a magpie – borrowing styles and ideas from diverse sources for whatever musical project he was working on. The practice of engineering has this same characteristic in that it willingly takes ideas, knowledge and techniques from wherever in pursuit of completing its goal. Further, Engineering is, at least in part, in agreement with Fyodor Dostoevsky – ‘if everything on Earth were rational, nothing would happen’. Against such a background it is proposed that a framework based on both philosophy and the history of engineering, science and technology constitutes a valid footing upon which engineers can be enabled to see and develop their profession in a suitably rounded manner.

Electric-powered wheelchairs as an assistive technology
(2008)
O'Dwyer, Aidan; Basu, Malabika; Coyle, Eugene
Abstract:
This paper briefly outlines recent work done, particularly in control systems, for electric powered wheelchairs. These mobility aids, first developed in the 1950’s [1], were improved with the incorporation of microprocessors. The requirement for mobility aids in general is rising; for example, it is reckoned that 1.5% of the U.K. population require such aids. As an assistive technology, electric powered wheelchairs have many benefits. Nevertheless, a reliable and robust such wheelchair has still to evolve.

Engineering Education in the US and the EU
(2009)
Coyle, Eugene
Abstract:
Systems for the education of engineers in the US and the EU differ in significant ways. In this chapter we describe and reflect upon differences in accreditation policies and procedures, curriculum structure and content, admissions criteria and student mobility. Within the US there is a surprising uniformity among both private and public university programmes in engineering education, due in large part to the acceptance of ABET’s (Accreditation Board for Engineering and Technology) authority in setting standards for curriculum content. Within the EU there is greater programme variety, although some degree of harmonization is in the works due to the Bologna Declaration. We describe and analyze current efforts in Europe aimed at establishing a pan-EU authority for accreditation - the EUR- ACE Framework. One topic in curriculum structure draws our attention - the perceived value of liberal studies in engineering and the potential for significant reform of the engineering curriculum in ...

Brunton, James; Blackledge, Jonathan; Coyle, Eugene; Kennedy, David; Schmidt-Walter, Heinz; Kohnke, Hans; Sauer, Gerhard; Schudt, Steffen; Hamilton, James
Abstract:
Fuel Cells offer a realistic, sustainable and clean alternative energy option for stationary and mobile applications. Hydrogen and fuel cell technologies are recognised by many as possible long term energy solutions, but to-date have failed to make an impact on the energy market. This is due to a number of key reasons, some of which include, efficiency, scale, accessories and power output. Applying fuel cells to small telecommunication components requires the applications of Micro and Nanotechnology, which have yet to be perfected to make them long lasting and cost effective. This paper outlines the reasons for commercialisation of fuel cells and supports the argument that utilising hydrogen technology should be done in an environmentally friendly manner from the offset to prevent further damage to the environment. In particular, the paper focuses on the research, design and development of a Single Alkaline Fuel Cell Test Bed and outlines the AFC's capabilities and limitations ...

Abstract:
Research into renewable energy sources has previously lacked sufficient investment. However, emphasis has now shifted and funding is being made available in a proactive manner by various governments eager to encourage renewable energy technology and reduce carbon taxes. Fuel Cells offer a realistic, sustainable and clean alternative energy option for stationary and mobile applications. Hydrogen and fuel cell technologies are recognised by many as possible long term energy solutions, but to-date, have failed to make an impact on the energy market. This is due to a number of key reasons, some of which include efficiency, scale, accessories and power output. For example, applying fuel cells to small telecommunication components requires the applications of Micro and Nanotechnology, which have yet to be perfected to make them long lasting and cost effective. This paper focuses on the design, engineering and development of a new Alkaline Fuel Cell outlining its capabilities and limitatio...

Engineering Science as Opposed to Natural and Applied Science

Abstract:
In exploring the epistemology of engineering science we propose a model of engineering. This model incorporates the goals of engineering, the approach to engineering (also called the engineering method) and the role of experience in engi-neering. The basis for understanding the nature of engineering science will be ex-plored, and will be contrasted with natural science. To begin, a large-scale engi-neering project that was successfully completed in Ireland many years ago is dis-cussed - specifically, the development of a megalithic passage tomb as an exemplar of the engineering method in structural design, project management and aesthetics. This exemplar firmly demonstrates that engineering method existed before the de-velopment and understanding of the relevant natural science. We next contrast the nature of engineering or engineering science and natural science. This discussion will further develop the engineering model, but will contrast the philosophical dif-ferences between eng...

Estimation of Wave Energy from Wind Velocity
(2013)
Blackledge, Jonathan; Coyle, Eugene; Kearney, Derek; McGuirk, Ronan; Norton, Brian
Abstract:
The aim of this paper is to report on a possible correlation between the Levy index for wind velocity and the mean Energy Density of sea surface waves in the same location. The result is based on data obtained from 6 buoys located around the coast of Ireland and maintained by the Marine Institute of Ireland and a further 144 buoys located at various locations off the coast of the United States of America and maintained by the National Data Buoy Centre. These buoys provide historical data on the wind velocity, wave height and wave period as well as other data on an hourly interval. Using this data, we consider the relationship between a stochastic model for the time variations in wave height that in turn, is based on a non-Gaussian model for the wind force characterised by the Ĺevy index. The results presented in this paper indicate the possibility of developing a method of estimating the energy and power densities of sea waves from knowledge of the wind velocity alone.

Exploiting Glottal Formant Parameters for Glottal Inverse Filtering and Parameterization
(2010)
O'Cinneide, Alan; Dorran, David; Gainza, Mikel; Coyle, Eugene
Abstract:
It is crucial for many methods of inverse filtering that the time domain information of the glottal source waveform is known, e.g. the location of the instant of glottal closure. It is often the case that this information is unknown and/or cannot be determined due to e.g. recording conditions which can corrupt the phase spectrum. In these scenarios, alternative strategies are required. This paper describes a method which, given the parameters of the glottal formant of the signal frame, can accurately parameterize the glottal shape source and vocal filter for a broad range of voice quality types and which is robust to the corruption of the phase spectrum. Index Terms: glottal inverse filtering, frequency domain, glottal models, glottal formant

Extended Nonnegative Tensor Factorisation Models for Musical Sound Source Separation
(2008)
Fitzgerald, Derry; Cranitch, Matt; Coyle, Eugene
Abstract:
Recently, shift-invariant tensor factorisation algorithms have been proposed for the purposes of sound souce separation of pitched musical instruments. However, in practice, existing alogorithsm require the use of log-frequency spectrograms to allow shift invariance in frequency which causes problems when attempting to resynthesise the separated sources. Further, it is difficult to impose harmonicity constraints on the recovered basis functions. This paper proposes a new additive synthesis-based approach which allows the use of linear-frequency spectrograms as well as imposing strict harmonic constraints, resulting in an improved model. Futher, these additional constraints allow the addition of a source filter model to the factorisation framework, and an extended model which is capable of separating mixtures of pitched and percussive instruments simultaneously.

Force Measurement Methods in Telerobotic Surgery: Implications for End-Effector Manufacture
(2008)
Callaghan, Dean; McGrath, Mark; Coyle, Eugene
Abstract:
Haptic feedback in telesurgical applications refers to the relaying of position and force information from a remote surgical site to the surgeon in real-time during a surgical procedure. This feedback, coupled with visual information via microscopic cameras, has the potential to provide the surgeon with additional ‘feel’ for the manipulations being performed at the instrument-biological tissue interface. This increased sensitivity has many associated benefits which include, but are not limited to; minimal tissue damage, reduced recuperation periods, and less patient trauma. The inclusion of haptic feedback leads to reduction in surgeon fatigue which contributes to enhanced performance during operation. Commercially available Minimally Invasive Robotic Surgical (MIRS) systems are being widely used, the best-known examples being from the daVinci® by Intuitive Surgical Inc. However, currently these systems do not possess force feedback capability which therefore restricts their use dur...

Generalised Prior Subspace Analysis for Polyphonic Pitch Transcription
(2005)
Fitzgerald, Derry; Cranitch, Matt; Coyle, Eugene
Abstract:
A reformulation of Prior Subspace Analysis (PSA) is presented, which restates the problem as that of fitting an undercomplete signal dictionary to a spectrogram. Further, a generalization of PSA is derived which allows the transcription of polyphonic pitched instruments. This involves the translation of a single frequency prior subspace of a note to approximate other notes, overcoming the problem of needing a separate basis function for each note played by an instrument. Examples are then demonstrated which show the utility of the generalised PSA algorithm for the purposes of polyphonic pitch transcription.

Harmonic distortion caused by EV battery chargers in the distribution systems network and its remedy
(2004)
Basu, Malabika; Gaughan, Kevin; Coyle, Eugene
Abstract:
An effective way to minimise harmonic pollution in power systems is by careful design of the equipment connected to them. It is important for designers of equipment associated with emerging technologies to be aware of the potential impact of their designs on power system quality. One such upcoming technology is electric vehicle (EV) battery charging which may contribute to high harmonic distortion in the power system during the charging period. The literature notes total harmonic distortion of up to 50%. These findings are the impetus behind the present paper, where an EV battery charger has been designed, with an inherent power quality control feature. A parallel power circuit topology has been proposed on an existing ferroresonant charger, which ensures that the THD of the input current remains within the acceptable harmonic distortion limits of the distribution system. The design and control of the battery charger are elaborated upon in the paper and simulation results are presen...

Harmonic Sound Source Separation using FIR Comb Filters
(2004)
Gainza, Mikel; Lawlor, Robert; Coyle, Eugene
Abstract:
A technique for separating harmonic sound sources using FIR comb filters is presented. First, a pre-processing task is performed by a multipitch estimator to detect the pitches that the signal is composed of. Then, a method based on the Short Time Fourier Transform (STFT) is utilized to iteratively extract the harmonics belonging to a given source by using FIR comb filters. The presented approach improves upon exising sinusoidal model approaches in terms of the perceptual quality of the extracted signal.

Harmonically Combined Contour Icons for Concurrent Auditory Display
(2006)
Cullen, Charlie; Coyle, Eugene
Abstract:
This paper considers the harmonic combination of basic melodic shapes known as contour icons in concurrent auditory displays. Existing work in the field (such as that concerning earcons) has considered the combination of patterns designed using low level cognitive features, and so effective streaming is difficult. This work investigates means by which musical patterns with high level cognitive features (such as contour) representing data values can be rendered concurrently, so that multiple data sets can be effectively conveyed using an auditory display. The detection and comprehension of harmonically combined contour icons was tested in comparison to those combined uniquely (non harmonically). Results suggest that significant improvement in pattern combination detection was made using harmonically combined contour icons, although limitations were observed due to the nature of the harmonic relations involved. Future work will investigate the most flexible methods of harmonic combina...

High Auality Time-scale Modification of Speech using a Peak Alignment Overlap-add Alogroithm (PAOLA)
(2003)
Dorran, David; Lawlor, Robert; Coyle, Eugene
Abstract:
The duration of a speech passage can be altered using audio time-scale modification techniques. Time-scale modification can be achieved in the time domain by segmenting the input signal into overlapping frames and recombining the frames with an overlap differing from the analysis overlap. We present a time-scale modification algorithm that uses a simple peak alignment technique to synchronise overlapping synthesis frames. The peak alignment overlap-add (Paola) algorithm also takes advantage of waveform properties to ensure a high quality output for the minimum number of iterations. The new algorithm produces a time-scaled output of approximately equal quality to that of an adaptive implementation of the commercially popular synchonised overlap-add (SOLA) algorithm, but offers a computational saving ranging from a factor of 15 (for a time-scale factor of 0.5) to 170 (for a time-scale factor of 1.1)

Independent Subspace Analysis using Locally Linear Embedding
(2003)
Fitzgerald, Derry; Coyle, Eugene
Abstract:
While Independent Subspace Analysis provides a means of blindly separating sound souces from a single channel signal, it does have a number of problems. In particular the amount of information required for separation of sources varies with the signal. This is a result of the variance-based nature of Principal Component Analysis, which is used for dimensional reduction in the Independent Subspace Analysis algorithm. In an attempt to overcome this problem the use of a non-variance based dimensional reduction method, Locally Linear Embedding, is proposed. Locally Linear Embedding is a geometry based dimensional reduction technique. The use of this approach is demonstrated by its application to single channel source separation and its merits discussed

Information Delivery on Mobile Devices Using Boolean Sonification Patterns

Cullen, Charlie; Coyle, Eugene
Abstract:
Sonification is the means by which non-speech audio can be used to convey information. Existing work has produced methods for delivering information in a wide range of fields, and recent work has considered the huge potential of mobile devices for Sonification. Boolean Sonification is a method of defining two related musical patterns as boolean conditions (true/false, yes/no etc.), such that one is considered contrary to the other by the listener. The final pattern set ideally comprises of two musical events that are closely enough related as to be considered a group, yet distinct enough to be perceived as separate entities. A java user interface is under development to allow Sonification to be configured by the user on the handset itself. Live testing is currently being performed.
