The Replenishment cycle contains five works that allude to the experience of sleep, beginning with awake drowsiness and ending with the piece inspired by rapid eye movement (REM) sleep, titled Conceiving Realities. This last piece is an intermedia work composed for chamber ensemble, live painting with biofeedback, computer, and audiovisual processing. This critical essay describes the composition of Conceiving Realities within the context of the Replenishment cycle, followed by a thorough analysis of the research involved in the technological aspects of the piece, and finally, a description of the instrumentation, notation, intermedia elements, and technology comprising the work. Conceiving Realities uses a system of interactions between painting, biofeedback, music, and video, in which a painter wears brainwave and heartbeat sensors that send data to a computer patch processing the sound of an ensemble as the painter listens and creates the painting while responding to the music. This requires a passive biofeedback system in which the painter is focused on listening and painting. The computer uses the data to process existing sounds, instead of synthesizing new lines. The score blends elements of traditional notation, graphics, and guided improvisation; giving the performers some creative agency. This alludes to the way in which scenarios in dreams occur without voluntary control of the dreamer. Finally, a camera captures the painting and projects three video screens applying individual types of processing to the original video stream, controlled in real time by the amplitude of the ensemble. All these elements create an immersive experience for the audience that is mediated by the interaction of sight and sound.

Purpose: Vibrotactile displays have been found to be beneficial in improving balance test scores that correlate with a decrease in fall rate in laboratory studies. Investigations of these devices have been limited to upright stance and have not been done in clinical settings. Furthermore, transitional movements facilitated by vibrotactile displays, such as forward lean and rise found in sit-to-stand, have not been investigated. A prospective study investigated the relationship between force platform vibrotactile intervention and balance test scores, sit-to-stand and falls in subjects with abnormal NeuroCom Sit-to-Stand test results and 2 or more self-reported falls within the last 6 months. Subjects: Subjects included 30 community-dwelling adults, aged 60 to 79 years, 10 as off-site controls, 10 as on-site controls, and 10 as on-site device intervention subjects. Method: The cohort is a prospective case/control study using Pearson r, paired sample t-test, multivariate analysis of variance (M)ANOVA), and Wilcoxon signed rank analysis to determine the relationship between standard of care physical therapy plus vibrotactile force platform device treatment and standard of care physical therapy only. The Berg Balance Scale (BBS), Dynamic Gait Index, functional independence measure-motor (FIM-Motor), NeuroCom Sit-to-Stand normative ratios, NeuroCom Comprehensive Report, and self-reported falls quantify change over time with repeated measure study design. Results: The study found a significant beneficial effect in the device intervention group which realized 39.5/56 to 51.2/56 mean score increase in Berg Balance Score, increase in mean Dynamic Gait Index from 11.7/24 to 19.8/24, mean increase in FIM-Motor from 16.4/21 to 19.5/21 and decrease in self-report falls from 4 to 2 by intervention Day 14. These finds encourage further investigation of vibrotactile force platform devices.

This master thesis dwells on EEGbiofeedback (also called Neurofeedback) interface of human brain and the computer and its concrete realization in Java programming language. This system is founded on the basis of the computer, which is accomplishing biological feedback (biofeedback) and the electroencephalography (EEG) by helping that state's scanning of user's brain is realized. By this way is possible to practise the human brain effectively to achieve better concentration, the elimination of sleeping and learning deficiency. Hereafter is the suggestion of direction control of computer mouse by EEG device incorporated, which makes it possible for the man to regulate the direction of the cursor's movement on the screen by the frequency of brain's oscillation. The motivation for solution of this problem is the effort to help to handicapped people to communicate with surrounding world. The introduction of this paper contains the basic facts about human brain, electroencephalography and EEG biofeedback. The following chapters dwell on the specification of claims to developed application, its suggestion and description of actual realization. The final part relates to the BCI (Brain-Computer Interface) systems and suggestion of computer's control by EEGappliance with evaluation of attained results.

Dissertation submitted in partial compliance with the requirements for the Masters’ Degree in Technology: Chiropractic, Durban University of Technology, 2013. / Background : Core strengthening may improve athletic ability by providing stability to the trunk, and as a result, stabilising the pelvis. The leverage from which cyclists generate power may be enhanced as a result of a stable pelvis, thereby improving the cyclist’s performance. In the popular, highly competitive sport of cycling, performance enhancement is much sought after. Despite its widespread use, research involving core strengthening in sporting situations is lacking, with studies investigating the effect of a core strengthening programme on cycling performance yet to be investigated. Objectives : To determine the participants’ cycling speed, power, cadence and completion time, and core strength in terms of objective findings, pre- and post- core strengthening intervention, in the whole sample and within the two age strata. To determine the participants’ heart rate in terms of objective findings, and the rate of perceived exertion in terms of subjective findings, pre- and post- core strengthening intervention, in the whole sample and within the two age strata. To determine the participants’ perception of change in speed, power and cadence post- intervention, in the whole sample and within the two age strata. Method : Forty-two asymptomatic cyclists performed two 1.5 km time trials, pre- and post- core strengthening intervention. Core strength assessments were performed pre- and post- intervention, using the Pressure Biofeedback Unit, and the maximum and average speed (km/hr), power (w) and cadence (rpm), and completion time (s) were recorded pre- and post- intervention, using the Computerised Electromagnetic Roller resistance Ergometer (Tacx Trainer). Heart rate and rate of perceived exertion (RPE) were recorded pre- and post- intervention, as well as the participant’s perception of change in speed, power, and cadence post- intervention. SPSS version 20 (SPSS Inc) was used to analyse the data, in the whole sample and stratified into two age strata. Results : ll cycling performance indicators, speed, power, cadence and completion time showed a significant improvement post- intervention, in the whole sample, and within the two age strata. Core strength indicators showed a significant improvement post- intervention, in the whole sample and within the two age strata. A significant decrease in rate of perceived exertion and corresponding heart rate measurements post- intervention was observed in the whole sample. Similarly, the younger age strata reflected a significant decrease in rate of perceived exertion, however heart rate measurements were not significant. In contrast, the older age strata showed significant changes in heart rate measurements, with no significance in rate of perceived exertion measurements. The majority of participants experienced an increased perception in all outcomes post- intervention. Conclusions: The results of this study found that core strengthening had a statistically significant effect (p < 0.001) on cycling performance, both in terms of objective and subjective findings. Future studies could address the effect of core strengthening in an endurance setting.
