On The Use Of A Dynamic Hybrid Tempo Detection Model For Beat Tracking, Mikel Gainza Jan 2010

On The Use Of A Dynamic Hybrid Tempo Detection Model For Beat Tracking, Mikel Gainza

Conference papers

In this paper, an approach that estimates the times at which musical beats occur is presented. The system uses a hybrid multi-band decomposition in order to estimate the music tempo. Following this, beat events are tracked by using a dynamic programming approach, which is updated by using short time tempo estimates. The hybrid decomposition is used in order to calculate the tempo by using different onset detection functions in different frequency bands. In addition, a method that estimates which frequency bands provide reliable periodicities is also presented. The accuracy of the model is evaluated by comparing the presented system against …

Quality Indicators For Engineering And Technology Education, Michael Dyrenfurth, Mike Murphy, Gary Bertoline Jan 2010

Quality Indicators For Engineering And Technology Education, Michael Dyrenfurth, Mike Murphy, Gary Bertoline

Conference papers

In recent years the development and use of university rankings, comparisons, and/or league tables has become popular and several methodologies are now frequently used to provide a comparative ranking of universities. These rankings are often based on research and publication activity and also not uncommonly focus on indicators that can be measured rather than those that should be measured. Further, the indicators are generally examined for the university as a whole rather than for university divisions, departments or programs. Implicit also is that placement in the rankings is indicative of quality. This paper provides an overview of the methodologies used …

Gutiérrez-Tauste, A. Jorge, M. Faccini, G. Noriega, M. Di Lorenzo, M. Cocca, M. Avella, M. Errico, G. Gentile, John Doran, Brian Norton, S. Baluschev, J. Bistué Guardiola, A. Robles Molina, J. Puigdollers, C. Voz, S. Daren, F. Tsvetkov, A. Pashov

Conference Papers

Organic cells and dye-sensitized cells developed to-date have a narrow active absorption range, relative to the spectral range of the available solar resource. Their efficiency could be significantly enhanced through a process of down-shifting (DS) and up-conversion of non-absorbable photons converting them to photons better matching the spectral response of the particular solar cell. The DS molecules must exhibit a large Stokes shift and high luminescent quantum yield when incorporated in the downshifting polymer layer. In this paper, the QY of a downshifting Europium (III) complex in solution is determined using two distinct experimental techniques. The QY is measured for …


Broadening Ethics Teaching In Engineering: Beyond The Individualistic Approach, Eddie Conlon, H. Zandvoort Jan 2010

Broadening Ethics Teaching In Engineering: Beyond The Individualistic Approach, Eddie Conlon, H. Zandvoort

Articles

There is a widespread approach to the teaching of ethics to engineering students in which the exclusive focus is on engineers as individual agents and the broader context in which they do their work is ignored. Although this approach has frequently been criticised in the literature, it persists on a wide scale, as can be inferred from accounts in the educational literature and from the contents of widely used textbooks in engineering ethics. In this contribution we intend to: (1) Restate why the individualistic approach to the teaching of ethics to engineering students is inadequate in view of preparing them …

Articles

The microwave (MW)-assisted formation of ZnO micro-javelins from zinc nitrate and urea in aqueous solution is described. The particles (named as ‘micro-javelins’ because of their high aspect ratio and needle-like tips) grow hexagonally with well-defined facets in the h0110i direction and pointed tips in (0001) direction. Powder X-ray diffraction patterns show the appearance of a strikingly dominant (1000) orientation. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) investigations reveal the morphological evolution of these hexagonal ZnO particles with time. The effect of precursor concentrations, counterion type andMWirradiation power and their consequent influence on pH and Zn2+ ion concentration are …

Sustainable Design: A Case Study In Energy Systems, Eugene Coyle, Marek Rebow Jun 2009

Sustainable Design: A Case Study In Energy Systems, Eugene Coyle, Marek Rebow

Books/Book chapters

Since the publication of the UN climate report in 2007, most countries now agree that recent climate change has occurred as a result of human intervention and that it will require fast and profound measures to reduce this negative imprint imposed upon nature. Central to this is the need to radically reduce CO2 emissions resulting from combustion of carbon-based energy resources to meet global energy demands. Greater measures must be taken to develop new non-combustion based technologies, in addition to using low-carbon energy resources. Increasing energy efficiency and using energy wisely will also feature in reducing emissions. Sustain-able Energy is …

Digital Supply Chains: Towards A Framework For Software Distribution, Colm Ryan, Claudia-Maria Wagner, Edward Sweeney, Emilio Esposito, Pietro Evangelista

Conference papers

This paper assesses the effect of non-physicality of a digital product - software - on SCM practice. A number of in-depth, one-on-one interviews were held in 8 software companies that predominantly supply to enterprise customers on a global scale. The aim was to explore distribution challenges within software supply chains and how companies are addressing these challenges. The research has identified three different classes of software distribution models: One, which tends to rely on traditional physical infrastructures and paradigms, and two others that better exploit the properties of the digital products.

Uniarab: An Universal Machine Translator System For Arabic Based On Role And Reference Grammar, Brian Nolan, Yasser Salem Jan 2009

Uniarab: An Universal Machine Translator System For Arabic Based On Role And Reference Grammar, Brian Nolan, Yasser Salem

Conference Papers

This paper presents a machine translation system (Hutchins 2003) called UniArab (Salem, Hensman and Nolan 2008). It is a proof-of-concept system supporting the fundamental aspects of Arabic, such as the parts of speech, agreement and tenses. UniArab is based on the linking algorithm of RRG (syntax to semantics and vice versa). UniArab takes MSA Arabic as input in the native orthography, parses the sentence(s) into a logical meta-representation based on the fully expanded RRG logical structures and, using this, generates perfectly grammatical English output with full agreement and morphological resolution. UniArab utilizes an XML-based implementation of elements of the Role …
