The Possibilities Of A Line: Marking The Glissando In Music, Cat Hope, Michael Terren

Research outputs 2014 to 2021

The glissando as it is deployed in Western art music notation carries with it a number of challenges to the hegemony of traditional harmony, rhythm, and notation. The glissando embodies the smooth line, unlike the striated pitch-time space of traditional Western music, which aligns the glissando to many philosophical concepts, as well as mathematical, scientific, and architectural disciplines. Select works by Iannis Xenakis, James Tenney and Giacinto Scelsi are discussed for their development of glissandi as integral formal components, especially around the glissando’s tendency to encourage stasis. Compositional attempts to combine the nature of glissandi with drone in the author’s …

A Multi-Point 2d Interface: Audio-Rate Signals For Controlling Complex Multi-Parametric Sound Synthesis, Stuart James

Research outputs 2014 to 2021

This paper documents a method of controlling complex sound synthesis processes such as granular synthesis, additive synthesis, timbre morphology, swarm-based spatialisation, spectral spatialisation, and timbre spatialisation via a multi-parametric 2D interface. This paper evaluates the use of audio-rate control signals for sound synthesis, and discussing approaches to de-interleaving, synchronization, and mapping. The paper also outlines a number of ways of extending the expressivity of such a control interface by coupling this with another 2D multi-parametric nodes interface and audio-rate 2D table lookup. The paper proceeds to review methods of navigating multi-parameter sets via interpolation and transformation. Some case studies are …

Unsynchronized Scanning With A Low-Cost Laser Range Finder For Real-Time Range Imaging, Isa Hatipoglu

All ETDs from UAB

Range imaging plays an essential role in many fields: 3D modeling, robotics, heritage, agriculture, forestry, reverse engineering. One of the most popular range-measuring technologies is laser scanner due to its several advantages: longer range, highly precise and real-time measurement capabilities, no lighting condition dependency, and less computational power requirement. However, laser scanners are very costly. Their high cost limit their usage in applications with low-cost limitation, especially for static environments like heritage sites. In this work, we present an unsynchronized scanning with a low-cost laser range finders (LRFs) to decrease scanning period and reduce vibrations caused by “scan-stop” in synchronized …

Laboratory-Scale Investigations Of Low-Permeability Porous Media By Analysis Of Transient Pressure Measurements, Michael Joseph Hannon

All ETDs from UAB

To provide a greater understanding of critical parameters of ultra-tight geologic formations such as shales, this report considers alternative approaches to the laboratory-scale pressure-pulse-decay permeametry method. These include new analytical models with which to analyze data from the principal rapid pulse-decay variants used in professional laboratories today. Novel revisions to the pulse-decay method are suggested and compared, in theory, against existing technologies. A new experimental procedure for the assessment of whole-core cylindrical samples is proposed that simultaneously determines the porosity and apparent permeabilities parallel and perpendicular to the native bedding plane from a single test on a single cylindrical core …

Spacers placed beneath the prepared tooth elevated #19 in the typodont and controlled the tooth margin height relative to the gingival margin. The TDS was used as an intraoral scanner. A total of 50 scans were made with 5 groups of 10 scans each. In Group 1 (control) the prepared tooth …

Increasing Accuracy Of Dietary Assessments By Regular-Shape Recognition And Photogrammetry, Ihsan K. Hakima

All ETDs from UAB

There is interest in determining the amount of food consumed during dietary studies using technology. Interviews of patients and/or participants can result in inaccuracies in reported food intake. Using food journals or diaries can be more accurate, but depends on participants' motivation to record food intake during meals. Technology can make it easier to record food intake. Previous work utilizing technology has included using single images and a virtual model for food estimation, projecting a circular light on the image to use as a reference, and using a device with a laser to determine distance. Another method uses a wearable …

Identification Of Blood Biomarkers For Use In Point Of Care Diagnosis Tool For Alzheimer's Disease, E. Jammeh, P. Zhao, C. Carroll, S. Pearson, E. Ifeachor

Peninsula Medical School

Early diagnosis of Alzheimer's Disease (AD) is widely regarded as necessary to allow treatment to be started before irreversible damage to the brain occur and for patients to benefit from new therapies as they become available. Low-cost point-of-care (PoC) diagnostic tools that can be used to routinely diagnose AD in its early stage would facilitate this, but such tools require reliable and accurate biomarkers. However, traditional biomarkers for AD use invasive cerebrospinal fluid (CSF) analysis and/or expensive neuroimaging techniques together with neuropsychological assessments. Blood-based PoC diagnostics tools may provide a more cost and time efficient way to assess AD to …

The Control Of Schwann Cell Myelination During Development And After Nerve Injury, Sheridan Roberts

Other Faculty of Health Theses

Schwann cells are the principal glial cell of the peripheral nervous system and are responsible for axon maintenance, regeneration and increasing saltatory conduction of neurons. Schwann cell differentiation and myelination is mediated by a core network of transcription factors and signalling pathways, which have been divided into two groups; positive and negative regulators. Sox10, NFATc4, Oct6, Krox20 and the ERK 1/2 signalling pathway have been characterised as positive regulators of Schwann cell differentiation and myelination; with Sox10 and Krox20 also playing critical roles in myelin maintenance. On the other hand, transcription factors cJun, Pax3, Id2 and signalling pathways Notch and …

Altitudinal Shifts Of The Native And Introduced Flora Of California In The Context Of 20th-Century Warming, A. Wolf, Naupaka B. Zimmerman, W. R. Anderegg, P. E. Busby, J. Christensen

Biology Faculty Publications

Aim: The differential responses of plant species to climate change are of great interest and grave concern for scientists and conservationists. One underexploited resource for better understanding these changes are the records held by herbaria. Using these records to assess the responses of different groups of species across the entire flora of California, we sought to quantify the magnitude of species elevational shifts, to measure differences in shifts among functional groups and between native and introduced species, and to evaluate whether these shifts were related to the conservation of thermal niches.

Location: California.

Methods: To characterize these shifts in California, …

Hierarchical Reinforcement Learning As Creative Problem Solving, Tr Colin, T Belpaeme, A Cangelosi, N Hemion

School of Engineering, Computing and Mathematics

Although creativity is studied from philosophy to cognitive robotics, a definition has proven elusive. We argue for emphasizing the creative process (the cognition of the creative agent), rather than the creative product (the artifact or behavior). Owing to developments in experimental psychology, the process approach has become an increasingly attractive way of characterizing creative problem solving. In particular, the phenomenon of insight, in which an individual arrives at a solution through a sudden change in perspective, is a crucial component of the process of creativity. These developments resonate with advances in machine learning, in particular hierarchical and modular approaches, as …

A Parallel Evolutionary Approach To Solving Systems Of Equations In Polycyclic Groups, Matthew J. Craven, Daniel Robertz

School of Engineering, Computing and Mathematics

AbstractThe Anshel–Anshel–Goldfeld (AAG) key exchange protocol is based upon the multiple conjugacy problem for a finitely-presented group. The hardness in breaking this protocol relies on the supposed difficulty in solving the corresponding equations for the conjugating element in the group. Two such protocols based on polycyclic groups as a platform were recently proposed and were shown to be resistant to length-based attack. In this article we propose a parallel evolutionary approach which runs on multicore high-performance architectures. The approach is shown to be more efficient than previous attempts to break these protocols, and also more successful. Comprehensive data of experiments …

Identifying Users By Network Traffic Metadata, G Alotibi, N Clarke, F Li, S Furnell

School of Engineering, Computing and Mathematics

Insider misuse is become a major threat to many organisations. This is due to the knowledge that might have about the organization's security infrastructure. Therefore, a wide range of technologies have been developed to detect/prevent the insider misuse. Beyond detecting, there is a need to investigate the misuse and identify the individual perpetrating the crime. From a networking perspective, the investigations currently rely upon analysing traffic based upon two approaches: packet-based-approach and flow-based approach. However, a serious limitation in these approaches is the use of IPs addresses to link the misuse to the individual. However, IPs addresses are often not …
