Automating Ornamentation Transcription, Mikel Gainza, Eugene Coyle

Conference papers

A novel technique for detecting single and multi-note ornaments is presented. The system detects audio segments by utilising and onset detector based on comb filters (ODCF), which is capable of detecting very close events. In addition, a novel method to remove spurious onsets due to offset events is introduced. The system utilises musical ornamentation theory to decide whether a sequence of audio segments correspond to an ornamentation musical structure. In order to evaluate the results, a database of signals produced by different players using the three different instruments has been utilised. The results represent a step forward towards fully automating …

Towards A Personal Automatic Music Playlist Generation Alogorithm: The Need For Contextual Information, Gordon Reynolds, Dan Barry, Ted Burke, Eugene Coyle

Conference papers

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 …

Automatic Bar Line Segmentation, Mikel Gainza, Dan Barry, Eugene Coyle

Conference papers

A method that segments the audio according to the position of the bar lines is presented. The method detects musical bars that frequently repeat in different parts of a musical piece by using an audio similarity matrix. The position of each bar line is predicted by using prior information about the position of previous bar lines as well as the estimated bar length. The bar line segmentation method does not depend on the presence of percussive instruments to calculate the bar length. In addition, the alignment of the bars allows moderate tempo deviations.

A Brief Introduction To Speech Synthesis And Voice Modification, Alan O'Cinneide, David Dorran, Mikel Gainza

Conference papers

For both engineers and linguists, the computer synthesis of natural speech is an objective that would provide many useful applications to human-computer interaction, including the realm of electro-acoustic music. The purpose of this paper is to introduce the area of speech synthesis by providing an overview of the three main methods of computer speech synthesis; namely concatenative, articulatory and formant syntheses. Some aspects of the current state of the technology are illuminated and the final section will explain the author’s motivation and current research approach to the field of voice modification.

Time Signature Detection By Using A Multi Resolution Audio Similarity Matrix, Mikel Gainza, Eugene Coyle

Conference papers

A method that estimates the time signature of a piece of music is presented. The approach exploits the repetitative structure of most music, where the same musical bar is repeated in different parts of a piece. The method utilised a multi-resolution audio similarity matrix approach, which allows comparisons between longer audio segments (bars) by combining comparisons of shorter segments (fraction of a note). The time signature method only depends on musical structure, and does not depend on the presence of percussive instruments or strong musical accents.

The Impact Of External, Socially Synthetic Forces, Such As Mass Media, Video Games, And The Internet On Human Behavior, George Stanley Reeley Jr.

Essays in Education

This essay explores the controversial hypothesis of reciprocal determinism, a subset of the Social Cognitive Theory developed by Albert Bandura, Ph.D. The hypothesis suggests that external forces likely influence the behavior of an individual, and in turn, the individual reshapes (reciprocally) society in an escalading cycle of manipulation and modification. Diverse perspectives are gathered from seminal books and peer-reviewed journals in an attempt to substantiate or conceivably refute the notion that mass media, the Internet, video games, and other forms of one-way and interactive technology may be stirring aggressive behavior (by way of modeling), as well as desensitizing children and …

Dialogic Communication In Collaborative Problem Solving Groups, Robert B. Innes

International Journal for the Scholarship of Teaching & Learning

Discourse, especially dialogic communication between students in collaborative problem-solving groups, plays a central role in educational reforms informed by learning science. This study examined the quality of discourse in problem-based learning groups in a university course. The study found a low incidence of high quality dialogue (dialogic communication, elaboration and co-construction of ideas, productive disciplinary discourse) in 12 one-hour planning meetings. The most competent students took leadership in groups and made the majority of the conceptual contributions. Although there was a reasonable amount of time spent connecting theories to cases, there was little time spent in high-level analysis and very …

Teachers’ Conceptions Of Teaching Service Statistics Courses, Sue Gordon, Peter Petocz, Anna Reid

International Journal for the Scholarship of Teaching & Learning

In this paper, we report on the results of a series of e-mail interviews with statistics educators around the world, focusing on their views of the nature of teaching statistics as a ‘service’ subject. What do they think are the important aspects of statistics to focus on in such servicing teaching? What do they think are the characteristics of good teachers? And how do they go about developing themselves as statistics teachers? We analyse their responses to these and other questions using a phenomenographic approach to identify an outcome space for their conceptions of teaching service statistics. We examine the …

Patent Symmetry, Alan L. Durham

Articles

The patent system suggests a natural symmetry if nonobvious changes are enough to distinguish a patentable invention from the prior art then further nonobvious changes should be enough to avoid infringing the patent Logical as this seems the courts have adopted the notoriously difficult standard of insubstantial differences rather than nonobviousness as the ultimate test of infringement In this article I consider the possibility of a genuinely symmetrical patent system and find the difficulties profound However I conclude that a semisymmetrical adaptation of the nonobviousness standard of patentability could provide a superior infringement analysis an analysis more objective in application …

Wind Loads For Petrochemical Structures, Samuel Amoroso

LSU Doctoral Dissertations

Techniques currently available to practicing engineers for estimating wind loads for petrochemical structures have little theoretical or experimental basis. This dissertation research is an effort to expand the understanding of wind effects on petrochemical and other, similar structures. Petrochemical structures introduce geometric scales into wind tunnel model simulations below what are common for enclosed structures. Wind tunnel experiments were performed to help determine whether this will introduce problems in achieving dynamic similarity between models and prototypes. The experiments did not reveal any clear indication that petrochemical structures cannot be modeled in wind tunnels at scales similar to those used for …

Effects Of Capping On Biodegradation Of Organic Contaminants In Sediments, Eun Ju Lee

LSU Doctoral Dissertations

Sediment capping remains an effective remediation technique for contaminated sediments due to its capability to contain contaminants and provide a sound habitat for indigenous biota. This research investigated the effect of capping on biodegradation of organic contaminants in Anacostia River sediments using both experimental and modeling techniques. 14C–Phenanthrene mineralization was monitored under various redox conditions in Anacostia River sediments. Mineralization of 14C–phenanthrene was strongly linked to sulfate reduction, which was the more energetic process than any other anaerobic condition in Anacostia sediments. Sulfate is a more promising terminal electron acceptor for intrinsic degradation in Anacostia River and other PAH contaminated …

Isolation And Characterization Of The Siamese Family: A Novel Class Of Cell Cycle Regulators In Plants, Michelle Lynn Churchman

LSU Doctoral Dissertations

Recessive mutations in the SIAMESE (SIM) gene of Arabidopsis result in multicellular trichomes harboring individual nuclei with a low ploidy level, a phenotype strikingly different from that of wild-type trichomes, which are single cells with a nuclear DNA content of approximately 16-32C. These observations suggested that SIM is required to suppress mitosis as part of the switch to endoreplication in trichomes. We demonstrate that SIM encodes a novel 14kD protein that is part of a small Arabidopsis gene family comprised of four members. Homologs exist in other dicots and in monocots, although no obvious animal homologs have been identified. SIM …

Parenting Experiences Of Eastern European Immigrant Professionals In The U.S.: A Qualitative Study, Olena Nesteruk

LSU Doctoral Dissertations

In 2004, the nation’s foreign-born population numbered approximately 35 million comprising about 12% of the total U.S. population (U.S. Census Bureau, 2005). Most studies of immigrants primarily research the two largest immigrant groups, those from Latin America and Asia, while little has been done with the less visible population of immigrants from Eastern Europe. Also, we know much about the experiences of low-income immigrants of color, but little about the experiences of white immigrant families in the professional ranks. A qualitative study was conducted with immigrant professionals from Eastern Europe to explore their experiences with raising children in a new …

Dit Frequency Based Incremental Attribute Selection For Gre., John D. Kelleher

Conference papers

The DIT system uses an incremental greedy search to generate descriptions, (similar to the incremental algorithm described in (Dale and Reiter, 1995) ) incremental algorithm). The selection of the next attribute to be tested for inclusion in the description is ordered by the absolute frequency of each attribute in the training corpus. Attributes are selected in descending order of frequency (i.e. the attribute that occurred most frequently in the training corpus is selected first).

Mediating Between Qualitative And Quantitative Representations For Task-Orientated Human-Robot Interaction., Michael Brenner, John D. Kelleher, Nick Hawes, Jeremy Wyatt

Conference papers

In human-robot interaction (HRI) it is essential that the robot interprets and reacts to a human’s utterances in a manner that reflects their intended meaning. In this paper we present a collection of novel techniques that allow a robot to interpret and execute spoken commands describing manipulation goals involving qualitative spatial constraints (e.g. “put the red ball near the blue cube”). The resulting implemented system integrates computer vision, potential field models of spatial relationships, and action planning to mediate between the continuous real world, and discrete, qualitative representations used for symbolic reasoning.

Students @ Play: Serious Games For Learning In Higher Education., Pauline Rooney

Conference papers

The rise of digital games over recent years has been exponential. While many are used for entertainment, digital games have also begun to permeate education — which has lead to the coining of the term ―serious games‖ [1]. Proponents of serious games argue that they hold enormous potential for learning [2], by embodying a range of pedagogical strategies. While some have adopted commercial games for use in the classroom, others have designed games specifically for educational purposes. However, designing complex and realistic serious games with limited budgets and resources is difficult. In addition, achieving a successful balance between the competing …

A Combinatorial Creativity Approach To Composing Traditional Irish Reels, Nan Zheng, Bryan Duggan

Conference papers

In this paper we describe a system that uses a corpus of 864 traditional Irish reels as input into an algorithm that composes new tunes. The system performs a structural analysis of the tunes in the corpus and also counts n-gram note sequences in the tunes. It then recombines n-gram note sequences together in structures from the corpus to generate new tunes. We further present our evaluation of the generated tunes as performed by 29 domain experts.

Enabling Access To Irish Traditional Music On A Pda, Bryan Duggan

Conference papers

This paper describes TunePal, a tool which facilitates convenient audio access to archive transcriptions of traditional tunes on a PDA. The main feature of TunePal is its ability to locate a tune by name or musical phrase from thousands stored on a PDA. TunePal enhances not only the recall of a musician using TunePal in a traditional music session, but also the acquisition of new repertoire. In this paper we briefly describe the sources of music that TunePal works on, present its main features, give a technical description and present efforts at disseminating TunePal to the wider traditional music community.
