Ultra-wideband (UWB) radars are getting much attention for maritime applications of smart and luxury ships in which UWB radar could be integrated into Bridge Navigational Watch & Alarm System - BNWAS. One of the interesting applications of UWB radar is vital signs measurement, which is a contactless method. UWB radar measures respiration and heartbeat rate by the motion of thorax for detecting and checking the state of people on the bridge.

A damage diagnosis method for trusses based on incomplete free vibration properties utilizing ensemble learning, e.g. Extreme gradient boosting (XGBoost), is presented in this work. Owing to the lack of measurement sensors, modal features are only measured at master degrees of freedom (DOFs) of a few first models instead of all DOFs of a structural system.

This study has established and calibrated a three-dimensional system model with a combination of hydraulics-waves and suspended sediment transport with measured data in the study area. Based on the calculated scenarios for the flood and the dry seasons, the results show the occurrence of MTZs in the riparian zone of the Mekong river with typical suspended sediment concentrations (SSC) ranging from 0.04–1.0 kg/m3 dry season and 0.2–1.1 kg/m3 flood season.

This study utilized the GIS-based Soil and Water Assessment Tool (SWAT) model to simulate the flow of Vu Gia - Thu Bon river basin at two hydrological stations - Nong Son and Thanh My, during the calibration period (2004 - 2010) and the verification period (2011 - 2015). The evaluation results of both periods, as measured by the NSE and R2 indexes, were found to be above 0.75.

The system of relations between the consumer and the seller has many factors that shape the dynamics of the market of goods and services based on the supply chain strategy. Supply chains satisfy customers by striving for delivering the right products to the right place at the right time, at the right quality and at the right quantity within an increasingly faster pace and lower cost. Theories of social entropy consider the system of social relations from the standpoint of the equilibrium of systems and their disproportion.

The article discloses methodological approaches to quantifying the level of penetration of block chain technologies into the regional socioeconomic environment in comparison to the supply chain strategies. Based on the methods of mathematical and statistical analysis, it allows you to formalize and convert a large array of data of a qualitative order into a single scale for measuring the process under study - the level of demand in the regional socio-economic environment for block chain technology.

This research focuses on two key research questions: how to measure spatial accessibility to green space in urban areas at fine resolution; and what is the status of spatial inequity in accessibility to green space in the MMA. Guided by the two research questions and based on a systematic review of literature on accessibility in general accessibility to green space in particular, a methodology has been developed for producing results needed to answer the research questions.

In this study, MCS is applied to compute the reliability of the nodes and the network under uncertain demand and roughness, and to determine how reliability is distributed among the various nodes of WDN, as well as assessing the reliability of the network as a series or parallel system. The effect of the resilience index on the nodal and network reliability is also assessed.

The objective of this thesis was to investigate the development of a micro-electromechanical system (MEMS) which can be implanted in the eye to provide continuous monitoring of glaucoma conditions. Current glaucoma monitoring involves taking laboratory based intra ocular pressure (IOP) measurements. The measurement of intraocular fluid flow and IOP parameters related to blockage formation in the eye require to be continuously monitored in Glaucoma.

Sufficient heat dissipation is crucial to the effective operation of friction based braking systems. Such cooling is generally provided by ensuring a sufficient supply of cooling air to the heated components, hence the aerodynamics in the region of the brake components is extremely important. The objective of the research was to develop an understanding of how aerodynamics could be used to improve the cooling of automotive disc brakes.

This thesis presents the design of a test asset system capable of testing GNSS receivers for speed accuracy and the Uncertainty of Measurements (UOM) analysis for this system. The test asset system utilises a variety of engineering solutions and is capable of maintaining high accuracy benchmarks in speed measurements. The test asset system has an UOM equal 0.4 km/h for the entire range of speeds used for GNSS speed testing. The system was designed, assembled and tested to ensure the system maintains its integrity and capability to test GNSS receivers for speed measurement.

This research addresses the call for future research by Brown and Treviño (2014) and Resick et al. (2006) to expand on ethical leadership research into other cultures. They believed employees in organisations use their ethical and cultural value systems as an absolute standard against which to measure the behaviour of members of the other culture, or they adopt the norms of the other culture. Previous studies have demonstrated several gaps within the ethical leadership literature; this research will address these gaps.

The primary aims of this thesis are: A) to measure the dependence of the DAPR20,10 on the size of the primary small photon field, and to relate this data to TPR20,10 of the reference field. B) to develop a method of using a large-area ionization chamber to compare the measured dosearea product to that calculated by a treatment planning system. C) To gain further understanding of the dose-area product by supplementing the results with 2D high resolution film dosimetry.

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.
