Non-invasive method of measuring airway inflammation : exhaled nitric oxide
… after commencement of inhaled corticosteroids. Methods A Dasibi Environmental Corporation Model 2107 chemiluminescence analyser was adapted specifically requiring a reduction in response time, which was achieved by modification of the circuitry and re-routing of the analogue signal directly to a …

Investigating a non-invasive method for determining muscle fiber composition
This study aims to explore a new method for analysis of muscle fiber type, using data collected from weightlifts on a leg press. A dynamic muscle model is developed, which utilizes the Descherevskii kinetic theory in combination with a muscle "matrix" model to predict net muscle contraction forces …

Non-invasive Method to Measure Energy Flow Rate in a Pipe
Current methods for measuring energy flow rate in a pipe use a variety of invasive sensors, including temperature sensors, turbine flow meters, and vortex shedding devices. These systems are costly to buy and install. A new approach that uses non-invasive sensors that are easy to install and less …

Interpreting Raman spectra using machine learning: towards a non-invasive method of characterizing single cells
Raman microscopy has the potential to non-destructively measure the biomolecular changes in single cells in a label-free manner. However, the extent to which Raman spectra can effectively infer biologically-relevant information is not well understood. In this thesis, we use machine learning methods …

The use of heart rate variability measurements as a non-invasive method of assessing affective state in horses
… are. Many physiological measures involve invasive procedures that contribute to the stress load of the individual and non-invasive methods often only determine the presence or absence of ‘stress’ or are dogged by interpretive problems.

Hardware and software for hand-held electrical impedance myography measurement prototype system
… the need for a more quantitative, objective, and non-invasive method of neuromuscular disease assessment. Currently, the best solution to this problem requires large, bulky pieces of equipment and the time-consuming placement of numerous individual electrodes. In this thesis, a new hardware device …

Quantification of left-to-right shunt through Patent Ductus Arteriosus by colour Doppler
The aim of this thesis was to develop a non-invasive method to quantify the size of a shunt through a patent ductus arteriosus (PDA) by ultrasound and to test its usability in clinical settings. There is no consensus regarding the optimal management strategy for a PDA in premature infants. …

Surface Velocity Measurements at the Aeolotron by Means of Active Thermography
… by means of thermography. An active thermography method was used to create heat patterns, which were visualized by an infrared camera. In contrast to other methods, this approach is a non-invasive method and does not disturb the surface properties. Several algorithms are explored on synthetic …

Inherent insensitivity to RF inhomogeneity in FLASH imaging
MRI as a non-invasive method for studying the internal structure and function of the human body was developed over the past three decades. In MRI, radiofrequency (RF) field inhomogeneity is an unavoidable problem in practice and becomes severe at high magnetic fields due to the dependence of B1 on …
