"Her panting heart beat measures of consent": Women's Sexual Agency in Eliza Haywood's Fiction
Through her texts depicting amorous adventures, Eliza Haywood engages with critical, contemporary discussions about power relations and consent in both social and legal constructs. Her texts resist the boundary between the private domain of interpersonal relationships and the public domain of …

Aspects of the sensitivity of juvenile Jasus lalandii and decapod excitable tissue to the water soluble fraction of crude oil
… major effect of the WSF of crude oil on Jasus heart beat rate was bradycardia. Furthermore, the greater the initial exposure concentration the sooner the heart beat frequency decreased. 5. Exposure of Jasus muscle fibres to the WSF of crude oil resulted in a shift of the resting membrane …

MIT Automated Auscultation System
… allow physicians to visualize both individual heart beats and a visual-prototypical heart beat constructed from a sequence of beats. They also permit doctors to listen to an audio-prototypical heart-beat, audio enhanced heart-beats that amplify clinically significant sounds, and slowed down …

Design and development of a low cost heart best monitor device using finger photoplethysmography technique :|bcircuit design and fabrication of a non-invasive heart beat monitoring device that employs reflectance and transmission mode photoplethysmography using parallel port interface and microcontroller PIC16F84A.
A low cost Heart Beat Monitoring device (HBMD) for detecting heart beat in beats per minute is presented in this thesis. An optical technique called “Photoplethysmography” is utilized by attaching to the base of the finger for monitoring beat to beat pulsation. Two major design issues addressed in …

In search of an appropriate leadership ethos: a survey of selected publications that shaped the Black Theology movement
… in Sub-Saharan Africa, in all spheres, is at the heart beat of this work. Questions and concerns over the quality of leadership in most countries in this particular region are reasons which have led to revisit and investigate the formative training of the current cohort of African leadership with …

Unsupervised segmentation of heart sounds
Digitized and recorded heart sounds contain significant diagnostic information, and are easily acquired in clinical practice. Part of a hypothetical diagnostic system is the segmentation subsystem which locates the boundaries between heartbeats. This thesis examines the design and performance of …

A multivariate investigation of driver performance changes during extended driving periods in a computer-controlled driving simulator
… (c) drivers exhibited significant increases in heart beat interval standard deviation and in body movement frequency over time. In all driving duration conditions, drivers exhibited significant degradations in their ability to respond to emergencies relative to their baseline driving performance …

Functional characterisation of the hypertrehalosaemic hormone from the Indian stick insect Carausius morosus: metabolic and myotropic studies
… the role of Carmo-HrTHs in stimulating the heart rate through myostimulation was also investigated. Two biological assays were used to assess the potencies of various analogues, in comparison to that of the native peptides: (1) the carbohydrate-mobilizing assay assessed the increase in …

Reducing Public Speaking Anxiety For Community College Students: The Effects of A Combination Anxiety Reduction Technique on Trait and State Anxiety
… state anxiety commonly experienced as irregular heart beat, dry mouth, sweaty palms, and feelings of exhaustion. The findings showed that the students in the control group who spoke in the second week had higher anxieties than did the other students. A dividend of this investigation was the …

Video-analysis inference automated ECG (VID-ECG): improving video-based heart rate detection and exposing security risks of ECG-based biometric authentication
… recent biometric authentication methods using heart signals in the form of ECG and its components have been proposed to be used as a unique security key for body area networks (BANs) to authenticate individuals and protect privacy and network security. In this thesis we show how compo- nents of …

A multimodal lens into vascular recovery in a preclinical model of peripheral arterial disease
… my parents Ali, and Aicha heard my first heart beat. This shouldn't be a surprise as the heart is the first organ to form and function during the developmental stages of the fetus. In the embryo, newly formed blood vessels provide the growing organs with the vital oxygen and nutrients …

Advanced Techniques for Cardiovascular Magnetic Resonance Imaging in Cases of Irregular Motion
… changes in the electrical excitation of the heart. This can cause irregular heart beat variations and result in very long scan times for the functional assessment of the heart in patients suffering from arrhythmia. This thesis presents new MRI methods which overcome these problems and allow …

Local maximum entropy approximation-based modelling of the canine heart
… infarcted canine left ventricle (LV) during one heart beat. The LV is idealised by a prolate spheroidal ellipsoid. It undergoes expansion during the diastolic phase, addressed by a non-linear passive stress model which incorporates the transversely isotropic properties of the material. The …

A vector based approach for high frequency prospective correction of rigid body motion in Magnetic Resonance Imaging (MRI)
… It was precise enough to track the subject’s heart beat and breathing and accurate to within one degree. A gradient field probe was then designed for position encoding. The probe measured the rate of change of the gradient magnetic fields using three mutually orthogonal pickup coils. Assuming …

Feasibility of microwave radar system for proton emission therapy control.
… or abdomen, it is important to monitor lung and heart motion, as these organs displace local tissues. Conventional methods used for measurement of a patient's vital signs become problematic because metal wires or leads of these systems interfere with the proton beam. Metal leads and wires deflect …

Analyzing the Impact of Wireless Multi-Hop Networking On Vehicular Safety
… safety messages for VCAST are piggy backed on heart beat messages and does not require any modifications to the existing vehicular communication standards. For investigating the second part, we implemented a realistic car following model and used string stability analysis as a metric for …

Influence of athlete heart rate, rate of perceived exertion, and anxiety in rowing practice and competition
… there is a significant correlation between heart rate (HR) and rate of perceived exertion (RPE) in rowing, how athlete perception of pre-race anxiety relates to HR and RPE, and how these variables change between practice and competition. Four subjects were tested over the course of their …
