Development of Real-Time Adaptive Noise Canceller and Echo Canceller

In this paper, the adaptive cancellation structure is firstdeveloped based on the LMS algorithm and FIR adaptivefiltering. Then the novel practical noise and echo cancellationsystems are built using the proposed adaptive technique andimplemented using TX320TMS67C13 DSKs, which are TexasInstruments’ Digital Signal Processing (TI DSP) boards.Although adaptive filtering is an exciting topic in which manyreal-life applications can be explored [1]-[6], [9], building such areal-time system is often challenging due to the use of theoreticalmath, advanced DSP knowledge and practical industrial hands-onexperience [1],[4]-[6],[9]. Therefore, this paper indicates that it ispossible to apply traditional mathematics in adaptive filteringtheory to real-time practical DSP systems. With the MATLABsoftware tool, we can simulate and verify various adaptivefiltering designs first. Then, development and implementation ofdifferent noise or echo cancellation systems with adaptive filteringtechniques can be successfully performed using the floating-pointdigital signal processor, TX320TMS67C13 DSK. Furthermore, itcan be shown that TX320TMS67C13 DSKs with their stereochannels offer more effective and flexible tools for various noisecancellation applications

Food Edu-Care in the Primary Curriculum: A collaborative case study in an inner city DEIS Gaelscoil

This applied case study explored the role of food education and its potential to nurture the lives of children who may experience disadvantage socially, culturally and economically. The research concedes at the outset that the role of ‘food’ in education is complex, that schools do not deal with curriculum matters alone but also with social justice policy issues, and that school-based ‘food poverty’ policy interventions to date are broadly motivated by nutritional concerns. The research was informed by a critical pedagogy perspective using a collaborative enquiry design focused on individual and collective agency at the school level. Multiple theoretical and analytical frameworks related to constructivist learning methodologies, educational psychology, and critical social theory framed the study. The research intervention in the inner-city DEIS Gaelscoil was at the invitation of the Parents’ Council and staff who collectively identified an urgent need for healthier eating practices and a shift to cross-curricular pedagogical practices to meet educational targets in literacy and numeracy. An Integrated Food Edu-Care curriculum module was collaboratively developed and delivered in Irish through weekly class sessions and field-trips. The integrated Food Edu-Care curriculum module consisted of; sixteen food and cooking lessons, a collaborative Hot Lunch Experience (Pedagogic Meal) and the creation of a ‘Foodbook’ as a class project. The curricular areas included in the integrated Food Edu-Care curriculum module included, Mathematics, Language, Social, Environmental and Scientific Education (SESE), Social Personal and Health Education (SPHE) and Visual Arts. The outputs from the research include an Integrated Food Edu-Care Pedagogical Guide for teachers and Pupils’ Activity Workbook, an ‘e-Foodbook’, educational videos, flashcards and posters in both English and Irish. The findings indicate that using a collaborative, experiential, caring, active and integrated Food Edu-Care curriculum module has the capacity to reach all learners and to build on classroom relationships, thereby facilitating social and emotional learning particularly in the area of self-efficacy and social skills. The research confirmed that such a curriculum module can incorporate seamless compensation for missed life chances and for on-going disadvantage. The thesis recommends a fifth domain of emotional and self-efficacy development needs among primary school children which is better facilitated by systemic policy change to school food provision and integrated curriculum with target-free pedagogies than by narrowly focused, targeted initiatives for free school lunches

Experimental Music and Collaboration: Developing Artistry Through Performance Practice

This project locates collaboration and collaborative performance as a potential site for artistic growth. This study analyzes six collaborative projects: composed pieces for electric guitar accompanying a staged performance of collaged texts, an audio-visual installation, the preparation of several short pieces to accompany choreographed dances, a 90-minute soundtrack to a performance mixed live, an ongoing improvisational duo, and a live visuals performance to accompany Sunburned Hand of the Man at Duke University. It traces the growth of my artistry while also providing a method for both doing and writing about collaboration. In addition, it offers a model for understanding collaborative compensation and evaluating collaborative structures. The study begins in 2015 at the beginning of my master’s degree coursework and ends in 2022 with the completion of this dissertation. Each chapter analyzes a unique performance I contributed to and provides a brief overview of the project, discusses my background with my collaborator, reviews any planning work, maps the influences that informed my creative choices, offers a description of my methods, recalls my memories of the performance event, and ends with a reflection on the collaborative process. The conclusion of this study explores collaboration across power dynamics and offers several models for collaborative structures and possibilities for payment and compensation both in academic and in popular and professional contexts

Towards a Practitioner Model of Mobile Music

This practice-based research investigates the mobile paradigm in the context of electronic music, sound and performance; it considers the idea of mobile as a lens through which a new model of electronic music performance can be interrogated. This research explores mobile media devices as tools and modes of artistic expression in everyday contexts and situations. While many of the previous studies have tended to focus upon the design and construction of new hardware and software systems, this research puts performance practice at the centre of its analysis. This research builds a methodological and practical framework that draws upon theories of mobile-mediated aurality, rhetoric on the practice of walking, relational aesthetics, and urban and natural environments as sites for musical performance. The aim is to question the spaces commonly associated with electronic music – where it is situated, listened to and experienced. This thesis concentrates on the creative use of existing systems using generic mobile devices – smartphones, tablets and HD cameras – and commercially available apps. It will describe the development, implementation and evaluation of a self-contained performance system utilising digital signal processing apps and the interconnectivity of an inter-app routing system. This is an area of investigation that other research programmes have not addressed in any depth. This research’s enquiries will be held in dynamic and often unpredictable conditions, from navigating busy streets to the fold down shelf on the back of a train seat, as a solo performer or larger groups of players, working with musicians, nonmusicians and other participants. Along the way, it examines how ubiquitous mobile technology and its total access might promote inclusivity and creativity through the cultural adhesive of mobile media. This research aims to explore how being mobile has unrealised potential to change the methods and experiences of making electronic music, to generate a new kind of performer identity and as a consequence lead towards a practitioner model of mobile music

The impact of environmental education delivery methods and outreach messaging on attitudes, interests, and intended-behavior changes toward nature

Environmental education (EE) is important for environmental awareness and stewardship. Involving youth and adults in EE ensures current and future generations will conserve natural resources. This thesis explores impacts of delivery methods on participants’ environmental attitudes and behaviors toward nature through middle school classroom- and camp-based EE instruction, focus group interviews with rural minority youth, and adult responses to aquatic conservation outreach messaging. I observed no difference in environmental attitudes between online versus in-person delivery of EE lessons for middle-schoolers. Outdoor-based learning may be more impactful for EE than experiential, classroom-based learning. Focus group outcomes suggested youth EE programs should capitalize on exploratory learning that allows for independence and safety from wildlife and community violence. Arkansas anglers who reside near aquatic invasive species (AIS) are more aware of Clean, Drain, Dry (CDD) messaging despite all anglers’ likeliness to perform pro-environmental behaviors. Consistent, targeted CDD messaging could help minimize AIS spread
