    As the population ages, health issues like injurious falls demand more attention. Wearable devices can be used to detect falls. However, despite their commercial success, most wearable devices are obtrusive, and patients generally do not like or may forget to wear them. In this thesis, a monitoring system consisting of two 24Ă—32 thermal array sensors and a millimetre-wave (mmWave) radar sensor was developed to unobtrusively detect locations and recognise human activities such as sitting, standing, walking, lying, and falling. Data were collected by observing healthy young volunteers simulate ten different scenarios. The optimal installation position of the sensors was initially unknown. Therefore, the sensors were mounted on a side wall, a corner, and on the ceiling of the experimental room to allow performance comparison between these sensor placements. Every thermal frame was converted into an image and a set of features was manually extracted or convolutional neural networks (CNNs) were used to automatically extract features. Applying a CNN model on the infrared stereo dataset to recognise five activities (falling plus lying on the floor, lying in bed, sitting on chair, sitting in bed, standing plus walking), overall average accuracy and F1-score were 97.6%, and 0.935, respectively. The scores for detecting falling plus lying on the floor from the remaining activities were 97.9%, and 0.945, respectively. When using radar technology, the generated point clouds were converted into an occupancy grid and a CNN model was used to automatically extract features, or a set of features was manually extracted. Applying several classifiers on the manually extracted features to detect falling plus lying on the floor from the remaining activities, Random Forest (RF) classifier achieved the best results in overhead position (an accuracy of 92.2%, a recall of 0.881, a precision of 0.805, and an F1-score of 0.841). Additionally, the CNN model achieved the best results (an accuracy of 92.3%, a recall of 0.891, a precision of 0.801, and an F1-score of 0.844), in overhead position and slightly outperformed the RF method. Data fusion was performed at a feature level, combining both infrared and radar technologies, however the benefit was not significant. The proposed system was cost, processing time, and space efficient. The system with further development can be utilised as a real-time fall detection system in aged care facilities or at homes of older people

    A Framework for Site-Specific Spatial Audio Applications

    Get PDF
    As audio recording and reproduction technology has advanced over the past five decades, increasing attention has been paid to recreating the highly spatialised listening experience we understand from our physical environment. This is the logical next step in the quest for increasing audio clarity, particularly as virtual reality gaming and augmented reality experiences become more widespread. This study sought to develop and demonstrate a technical framework for the production of site-specific audio-based works that is user-friendly and cost effective. The system was intended to be used by existing content producers and audio programmers to work collaboratively with a range of site-based organisations such as museums and galleries to produce an audio augmentation of the physicality of the space. This research was guided by four key aims: 1. Demonstrate a compositional method for immersive spatial audio that references the novel physical environment and the listener’s movement within it. 2. Describe a framework for the development and deployment of a spatial audio visitor technology system. 3. Prototype a naturalistic method for the delivery and navigation of contextual information via audio. 4. Deploy, demonstrate, and evaluate a spatial audio experience within a representative environment. The resulting system makes use of a range of existing technologies to provide a development experience and output that meets a clearly defined set of criteria. Furthermore, a case study application has been developed that demonstrates the use of the system to augment a selection of six paintings in a gallery space. For each of these paintings, a creative spatial composition was produced that demonstrates the principles of spatial composition discussed in this thesis. A spoken informational layer sits on top of this acting as a museum audio guide, featuring navigation using head gestures for a hands-free experience. This thesis presents a detailed discussion of the artistic intentions and techniques employed in the production of the six soundscapes, as well as an evaluation of the resulting application in use in a public gallery space

    Get PDF
    Having in mind the foundational idea not only of our Journal but also the INSAM Institute itself, the main theme of this issue is titled “Technological Aspects of Contemporary Artistic and Scientific Research”. This theme was recognized as important, timely, and necessary by a number of authors coming from various disciplines. The (Inter)Views section brings us three diverse pieces; the issue is opened by Aida Adžović’s interview with the legendary Slovene act Laibach regarding their performance of the Wir sing das Volk project at the Sarajevo National Theater on May 9, 2023. Following this, Marija Mitrović prepared an interview with media artist Leon Eckard, concerning this artist’s views on contemporary art and the interaction between technology and human sensitivity. An essay by Alexander Liebermann on the early 20th-century composer Erwin Schulhoff, whose search for a unique personal voice could be encouraging in any given period, closes this rubric. The Main theme section contains seven scientific articles. In the first one, Filipa Magalhães, Inês Filipe, Mariana Silva and Henrique Carvalho explore the process and details of technological and artistic challenges of reviving the music theater work FE...DE...RI...CO... (1987) by Constança Capdeville. The second article, written by Milan Milojković, is dedicated to the analysis of historical composer Vojislav Vučković and his ChatGPT-generated doppelganger and opera. The fictional narrative woven around the actual historical figure served as an example of the current possibilities of AI in the domain of musicological work. In the next paper, Luís Arandas, Miguel Carvalhais and Mick Grierson expand on their work on the film Irreplaceable Biography, which was created via language-guided generative models in audiovisual production. Thomas Moore focuses on the Belgium-based Nadar Ensemble and discusses the ways in which the performers of the ensemble understand the concept of the integrated concert and distinguish themselves from it, specifying the broadening of performers’ competencies and responsibilities. In her paper, Dana Papachristou contributes to the discussion on the politics of connectivity based on the examination of three projects: the online project Xenakis Networked Performance Marathon 2022, 2023Eleusis Mystery 91_Magnetic Dance in Elefsina European Capital of Culture, and Spaces of Reflection offline PirateBox network in the 10th Berlin Biennale. The penultimate article in the section is written by Kenrick Ho and presents us with the author’s composition Flou for solo violin through the prism of the relationship between (historically present) algorithmic processes, the composer, and the performer. Finally, Rijad Kaniža adds to the critical discourse on the reshaping of the musical experience via technology and the understanding of said technology using the example of musique concrète. In the final Review section, Bakir Memišević gives an overview of the 13th International Symposium “Music in Society” that was held in Sarajevo in December 2022

    This is the final version. Available on open access from IWA Publishing via the DOI in this recordOwing to climate change related uncertainties and anticipated population growth, different parts of the developing and the developed world (particularly urban areas) are experiencing water shortages or flooding and security of fit-for-purpose supplies is becoming a major issue. The emphasis on decentralized alternative water supply systems has increased considerably. Most of the information on such systems is either scattered or focuses on large scale reuse with little consideration given to decentralized small to medium scale systems. Alternative Water Supply Systems brings together recent research into the available and innovative options and additionally shares experiences from a wide range of contexts from both developed and developing countries. Alternative Water Supply Systems covers technical, social, financial and institutional aspects associated with decentralized alternative water supply systems. These include systems for greywater recycling, rainwater harvesting, recovery of water through condensation and sewer mining. A number of case studies from the UK, the USA, Australia and the developing world are presented to discuss associated environmental and health implications. The book provides insights into a range of aspects associated with alternative water supply systems and an evidence base (through case studies) on potential water savings and trade-offs. The information organized in the book is aimed at facilitating wider uptake of context specific alternatives at a decentralized scale mainly in urban areas. This book is a key reference for postgraduate level students and researchers interested in environmental engineering, water resources management, urban planning and resource efficiency, water demand management, building service engineering and sustainable architecture. It provides practical insights for water professionals such as systems designers, operators, and decision makers responsible for planning and delivering sustainable water management in urban areas through the implementation of decentralized water recycling
