This research has investigated the possibility of using two photoplethysmography (PPG) sensors to measure blood oxygen saturation and through this monitor a patient’s pulse at two sites; the ear and the finger. Using these two simultaneous and continuous measurements the ultimate aim is develop a method of monitoring blood pressure.

Blood pressure (BP) is an important and commonly used vital sign to monitor a patient’s health. Current methods for monitor blood pressure are unsuitable for continuous, uninterrupted measurement of blood pressure outside of a hospital setting as such methods are invasive and could pose risks if complications occur. This research has investigated the possibility of using two photoplethysmography (PPG) sensors to monitor a patient’s pulse at two sites; the ear and the finger.

This paper proposes a novel beamforming solution for multi-receiver synthetic aperture sonar (SAS), which uses gated continuous-wave (CW) pulses, based on the average value of equivalent sound velocity (ESV) when considering the change of the sound velocity with depth. The main beam can be steered to desirable positions with the proposed solution.

Both osteoarthritis (OA) and cardiovascular diseases (CVD) are prevalent conditions which often coexist. Vascular involvement in the pathogenesis of these diseases, as well as increased cardiovascular risk in OA patients give occasion to investigate arterial stiffness in OA. The aim of this study was to establish associations between OA and arterial stiffness.

In this study, the generalized nonlinear Schrödinger equation describing nonlinear wave propagation in optical fiber with all higher order effects such as higher order dispersion, self-phase modulation and Raman scattering is considered. Using the numerical method, the effects of the terms third order dispersion, Raman scattering on evolution of ultrashort pulses are investigated in detail.
