Music as Commentary:A portfolio of music compositions and supporting thesis
Get PDFThis thesis consists of a portfolio of music compositions, a written commentary, and links toaudio-visual recordings of the works submitted. The portfolio comprises eleven musical works: three choral and solo vocal works, five works for chamber forces up to eight instruments, one orchestral work, one work for solo piano, and a work for six pianos. The works presented in the portfolio draw inspiration from visual art and photography, poetry, lived experiences and socio-political events, and other music(s).In this project, I seek to address questions surrounding: i) the decontextualisation of borrowed, found and existing material, both live and pre-recorded; and ii) how music might reflect society and the communities in which it was created. Specifically, through my work, I look at:1. musical approaches to subverting preconceived notions of music through parody and mimesis;2. compositional techniques of fragmentation (‘distillation’), repetition, re-ordering, imitation, collage in my work to explore decontextualisation;3. intertextuality as a method of creating an embedded or ‘other’ narrative in my work;4. the influence of the extramusical on musical elements such as harmony, timbre, and structure;5. and, how modes of semi-improvisation, aleatoricism, and other performer-led compositional approaches has the potential to enhance my creative practice, expand its scope, and unlock new possibilities in my music.These discussions are contextualised with references to a range of music creators who have proved influential on my work including Caroline Shaw, Julia Wolfe, Nico Muhly, Ted Hearne, Julius Eastman, Gavin Bryars, and Louis Andriessen, particularly their applications of tonality, gesture, form, and orchestration. This project also draws conclusions on the prominence of extramusical inspiration in my music and how varying collaborative practices with professional and non-professional performers, visual artists and literary practitioners has enhanced and informed my creative process
Winged Things:Insects and Birds as Flying Messengers in Céline Arnauld’s Poetry
Get PDFThe metropolis and the machine are the epitome of modernity in the avant-garde but in the interstices of the cityscape the natural world persists. In the disrupted Dada poems of Céline Arnauld, from the 1920s through to the 1940s, collisions between the man-made and natural environment produce sparks of lyrical beauty and of anxiety. The skyline is punctuated both by aeroplanes and birds; the roar of trains and buzz of insects clash in soundscapes. From wasps to doves, Arnauld’s winged things frequent and transcend the anthropocentric environment. Unbound by man-made borders, they range across temporal and spatial environments, the real and imaginary. This essay considers how Arnauld used her flying messengers to negotiate complex experiences and ecologies of modernity. Albeit mapped to temporal moments in the twentieth century, it emerges that her points of enquiry and tensions – from migration to war, freedom to precarity – are startlingly relevant one hundred years later
A Side-channel Analysis of Sensor Multiplexing for Covert Channels and Application Fingerprinting on Mobile Devices
Get PDFMobile devices often distribute measurements from a single physical sensor to multiple applications using software-based multiplexing. On Android devices, the highest requested sampling frequency is returned to all applications even if other applications request measurements at lower frequencies. In this paper, we comprehensively demonstrate that this design choice exposes practically exploitable side-channels based on frequency-key shifting. By carefully modulating sensor sampling frequencies in software, we show that unprivileged malicious applications can construct reliable spectral covert channels that bypass existing security mechanisms. Moreover, we present a novel variant that allows an unprivileged malicious observer app to fingerprint other victim applications at a coarse-grained level. Both techniques do not impose any special assumptions beyond accessing standard mobile services from unprivileged applications. As such, our work reports side-channel vulnerabilities that exploit subtle yet insecure design choices in mobile sensor stacks
Design and numerical analysis of dual-core photonic crystal fiber-based biosensor
Get PDFIn this study, the coupling and the relative sensitivity characteristics of a Dual-Core Photonic Crystal Fiber (DC-PCF)-based liquid sensor are evaluated by employing the full-vectorial Finite element Method (FV-FEM). The simulation results demonstrate that coupling length of the proposed sensor varies between 2mm and 0.2mm length at wide wavelength range (800–1600 nm) for low index analytes (1.33–1.36). Besides, birefringence of order ≈ 10-4 is reported. It is found that analyte with 1.36 index reaches higher sensitivity levels. On the other hand, the coupling length of the proposed sensor can be optimized with the ellipticity ratio of the central core hole. Bending analysis on coupling length and optical power fluctuations is also reported. It is found that the power °ow in one core is increasing almost 90% towards the bending direction. The proposed structure with simple design parameters has a great potential in various biomedical applications including DNA detection and can also be employed as fibre-based refractometer in various sensing applications

More than two decades of research on IoT in agriculture:A systematic literature review
Get PDFAgriculture is one sector where the Internet of Things (IoT) is expected to make a major impact. Yet, its adoption in the sector falls behind expectations. The purpose of this paper is to present the state-of-the art of IoT in agriculture and investigate its slow adoption in the sector. The authors have undertaken a systematic review and a synthesis of 1355 relevant publications over the last decade. This literature review reveals that the “big three” barriers for the overall sector are cost, skills, and standardization. The lack of connectivity and data governance are two key reasons why most of the proposed IoT solutions are standalone systems of limited scope, while the majority of commercial IoT efforts focus on practices in the protected indoor environment. Lastly, the analysis of past research along the five layers of the IoT system architecture reveals limited attention to barriers and solutions at the business layer, which represents a research opportunity for information systems scholars
