Towards a Computer Assisted Violin Teaching Aid
(2004)
Fitzgerald, Derry; Charles, Jane; Coyle, Eugene
Abstract:
This paper presents a possible approach for developing a violin teaching aid based on violin pedagogy, sound analysis and comparison of beginner and good player recordings. This teaching aid is targeted at students who have difficulty listening attentively to the sounds they produce. It aims to draw their attention to the sound of a fault, offer correction and to train the user's ear to actively listen.

Towards a Method to Determine the Glottal Formant Parameters of Voiced Speech without Time-Domain Reference
(2010)
O'Cinneide, Alan; Dorran, David; Gainza, Mikel; Coyle, Eugene
Abstract:
This paper presents an approach to estimate the glottal formant parameters of the voicing source in the frequency-domain. The method is based on a simplified pole-zero interpretion of the prevalent Liljencrants-Fant (LF) model of glottal flow, and gives approximations for a broad range of pulses shapes. An advantage of the method is that, unlike other methods, it does not rely on time-domain references.

Towards a Personal Automatic Music Playlist Generation Alogorithm: the need for Contextual Information
(2007)
Reynolds, Gordon; Barry, Dan; Burke, Ted; Coyle, Eugene
Abstract:
Large music collections afford the listener flexibility in the form of choice, which enables the listener to choose the appropriate piece of music to enhance or complement their listening scenario on-demand. However, bundled with such a large music collection is the daunting task of manually searching through each entry in the collection to find the appropriate song required by the listener. This often leaves the listener frustrated when trying to select songs from a large music collection. In this paper, an overview of existing methods for automatically generating a playlist is discussed. This discussion outlines advantages and disadvantages associated with such implementations. The paper then hightlights the need for contextual and environmental information, which ultimately defines the listener's listening scenario. Environmental features, such as location, activity, temperature, lighting and weather have great potential as meta-data. Here, the key processes of a basic syste...

Towards Measuring Continuous Acoustic Feature Convergence in Unconstrained Spoken Dialogues
(2008)
Kousidis, Spyros; Dorran, David; Wang, Yi; Vaughan, Brian; Cullen, Charlie; Campbell, Dermot; McDonnell, Ciaran; Coyle, Eugene
Abstract:
Acoustic/prosodic feature (a/p) convergence has been known to occur both in dialogues between humans, as well as in human-computer interactions. Understanding the form and function of convergence is desirable for developing next generation conversational agents, as this will help increase speech recognition performance and naturalness of synthesized speech. Currently, the underlying mechanisms by which continuous and bi-directional convergence occurs are not well understood. In this study, a direct comparison between time-aligned frames shows significant similarity in acoustic feature variation between the two speakers. The method described (TAMA) constitutes a first step towards a quantitative analysis of a/p convergence.

TrioSon: a Graphical User Interface for Pattern Sonification
(2005)
Cullen, Charlie; Coyle, Eugene
Abstract:
The TrioSon software allows users to map musical patterns to input data variables via a graphical user interface (GUI). The application is a Java routine designed to take input files of standard Comma Separated Values (CSV) format and output Standard Midi Files (SMF) using the internal Java Sound API. TrioSon renders output Sonifications from input data files for up to 3 user-defined parameters, allocated as bass, chord and melody instruments for the purposes of arrangement. In this manner each parameter concerned is distinguished by its individual instrumental timbre, with the option of rendering any combination of 1 to 3 parameters as required. The software parses indexed input data relating to individual variables for each user-defined parameter, and provides the means to allocate musical patterns to each variable for Sonification using drag and drop functionality. Control over the Rhythmic Parsing of the Sonification is provided, alongside individual control of the volume, panni...

Understanding the Global Energy Crisis
(2014)
Coyle, Eugene; Simmons, Richard A.
Abstract:
We are facing a global energy crisis caused by world population growth, an escalating increase in demand, and continued dependence on fossil-based fuels for generation. It is widely accepted that increases in greenhouse gas concentration levels, if not reversed, will result in major changes to world climate with consequential effects on our society and economy. This is just the kind of intractable problem that Purdue University’s Global Policy Research Institute seeks to address in the Purdue Studies in Public Policy series by promoting the engagement between policy makers and experts in fields such as engineering and technology. Major steps forward in the development and use of technology are required. In order to achieve solutions of the required scale and magnitude within a limited timeline, it is essential that engineers be not only technologically-adept but also aware of the wider social and political issues that policy-makers face. Likewise, it is also imperative that policy m...

Using structured P2P overlay networks to build content sensitive communities
(2004)
Stacey, Paul; Berry, Damon; Coyle, Eugene
Abstract:
This paper details a proposed peer-to-peer system, which allows a user to join communities of other like-minded users in order to exchange files. Utilising the routing capabilities of Pastry, the proposed system includes an indexing service, which facilitates the creation of virtual rendezvous points for users with similar interests (manifested by shared keywords). Users are described by the content they store. By using vector space modelling techniques users can be grouped together to form content sensitive communities. The system is built to serve as the basis for a distributed archive of research papers. The system is designed to improve the efficiency of file searches over current P2P file sharing applications. Search requests result in a comprehensive set of relevant documents being returned as searching are based on semantic meaning rather than literal matching.

Using Tensor Factorisation Models to Separate Drums from Polyphonic Music
(2009)
Fitzgerald, Derry; Cranitch, Matt; Coyle, Eugene
Abstract:
This paper describes the use of Non-negative Tensor Factorisation models for the separation of drums from polyphonic audio. Improved separation of the drums is achieved through the incorporation of Gamma Chain priors into the Non-negative Tensor Factorisation framework. In contrast to many previous approaches, the method used in this paper requires little or no pre-training or use of drum templates. The utility of the technique is shown on real-world audio examples.

Using Virtual Reality to Enhance Electrical Safety and Design in the Built Environment
(2010)
Blackledge, Jonathan; Barrett, Martin; Coyle, Eugene
Abstract:
Electricity and the inherent risks associated with its use in the built environment have long since been a priority for the electrical services industry and also the general public who must live and work in this environment. By its nature virtual reality has the advantage of being safe for both the user and equipment. In addition, it offers the user an opportunity to be exposed to a range of scenarios and conditions that either occur infrequently or are hazardous to replicate. This paper presents a prototype desktop virtual reality model, to enhance electrical safety and design in the built environment. The model presented has the potential to be used as an educational tool for third level students, a design tool for industry, or as a virtual electrical safety manual for the general public. A description of the development of the virtual reality model is presented along with the applications that were developed within the model. The potential for virtual reality is highlighted with ...

Violin Sound Quality Detection
(2008)
Charles, Jane; Fitzgerald, Derry; Coyle, Eugene
Abstract:
Although much research has been completed on finding features for instrument recognition system, little work has focused on the violin's timbre space. Suitable features from which a computer can assess the quality of a violinist's playing have been sought and the classification of violin note sound quality is investigated in this paper. The eventual outcome of this work can be applied in various systems including the development of a violin or bowed string instrument teaching aid, in automatic music transcription and information retrieval or classification systems.

Wind Resource in the Urban Environment
(2012)
Blackledge, Jonathan; Coyle, Eugene; Kearney, Derek; Murphy, Eamonn; Rivas Duartes, Maria-Jose
Abstract:
The World Meteorological Organization (WMO) Commission for Instruments and Methods of Observation recognized the need to include in the 1996 WMO Guide to Instruments and Methods of Observation, WMO No. 8 a new chapter on Urban Observations (Oke 2006). There is an increasing demand for meteorological data to support building and urban design, energy conservation, micro -wind turbine installation, air quality, pollution control, insurance, wind engineering, etc. Over the last six years instrumentation has been installed at the Dublin Ins titute of Technology (DIT) in two separate locations to monitor the wind. Research has shown that the wind resource will vary quite considerably on a given site and this is due to local variations in topography, and other factors associated with wind and turbulence in the built environment.

Wind Turbine Power Quality Estimation Using a Lévy Model for Wind Velocity Data
(2011)
Blackledge, Jonathan; Coyle, Eugene; Kearney, Derek Joseph
Abstract:
The power quality of a wind turbine is determined by many factors but time-dependent variation in the wind velocity are arguably the most important. In this paper a non-Gaussian model for the wind velocity is introduced that is based on a Lévy distribution. It is shown how this distribution can be used to derive a stochastic fractional diffusion equation for the wind velocity as a function of time whose solution is characterised by the Lévy index. A numerical method for computing the L´evy index from wind velocity time series is introduced and applied to example wind velocity data for both rural and urban areas where, in the latter case, the index is observed to have a larger value. Finally, an empirical relationship is derived for the power output from a wind turbine in terms of the Lévy index using Betz law.
