Audio for Flow Monitoring in Wastewater
… systems but requires increased sensing and monitoring that can provide actionable information. Audio is underutilised as a sensor input despite fluid flow naturally generating sound through different physical processes. This thesis investigates low-cost non-invasive microphones for flow …

Optical Cerebral Blood Flow Monitoring of Mice to Men
This thesis describes cerebral hemodynamic monitoring with the optical techniques of diffuse optical spectroscopy (DOS) and diffuse correlation spectroscopy (DCS). DOS and DCS both employ near-infrared light to investigate tissue physiology millimeters to centimeters below the tissue surface. DOS …

Assessment of integrated green infrastructure-based stormwater controls in small to large scale developed urban watersheds
… water bodies, and decreased combined sewer overflow events. The main objective of this dissertation research was to examine the benefits of individual and integrated GI stormwater control practices at small to large scales in urban watersheds. The hypothesis of this research is: "Retrofitting …

Dynamic wind turbine wake trajectory control: Strategies and real-time validation
… slower yaw actuation rates compared to inflow change rate cause time-varying downstream-rotor-wake overlap conditions, diminishing its benefits. To accommodate for inflow variations, closed-loop wake control can be an effective approach to minimize wake trajectory uncertainty. In this …

Aesthetic pollutant loadings in upstream combined sewers.
… standard of discharges from combined sewer overflows is necessary to meet the challenges set by the EC Urban Waste Water Treatment Directive (1991). To prevent aesthetic pollutants being discharged from a CSO, it is first necessary to gain an understanding of the quantity and temporal …

Compressible Flow Characterization Using Non-Intrusive Acoustic Measurements
… work, the use of acoustics for non-intrusive flow monitoring in compressible flows is explored and a novel sonic anemometry and thermometry (SAT) technique is developed. Using multiple arrangements of SAT equipment, a compressible acoustic tomography technique was also developed to resolve …

A computer vision approach for sewer overflow monitoring
… States. Under extreme wet conditions, excess inflow which is beyond the capacity of CSS results in Combined Sewer Overflows (CSOs); the consequence being direct discharge of untreated water into the environment. Current CSO monitoring methods rely on in situ placement, where the sensors are …

Mitigation of Different Network Attacks and Optimization in Software Defined Network
… a datacenter we need to monitor all of the flows. Some of the free virtual machines (VMs) can be used as traffic monitors. The monitoring process induces some network overhead which should be the lowest for the best performance. Monitoring becomes more challenging when the number of monitors …

The Dynamics of Coarse Sediment Transfer in an Upland Bedrock River
… sediment has been quantified through field monitoring of the sediment characteristics, repeat magnetic tracer surveys and in situ bed load impact sensors. This was carried out in conjunction with surveys of channel morphology, using terrestrial laser scanning and repeat dGPS surveys and …

Aqueous carbon losses from the Glenfeshie Mòine Mhór
… a nested design to capture data using continuous monitoring systems, grab sampling and flow monitoring, the hydrology of the peatland in relation to river flow was analysed. It was found that there were no significant differences between the monitored streams in relation to the catchment specific …

Development of semi-empirical models to measure mass flow rate of solids in an air seeder
… in the 1950s, it still lacks in the area of mass flow measurement of conveyed solids. An effective method of on-line seed flow monitoring is important to reduce product wastage and also, to anticipate plugging in the lines. The goal of this research has therefore been to develop methods to measure …

Enhanced Soil Moisture and Streamflow Estimation in Ungauged or Data-Scarce Watersheds
… or pollutant export) and integrated (streamflow) watershed responses. While streamflow is commonly used to constrain model parameters due to its availability and integrative nature, the issue of equifinality, where multiple parameter sets yield similar streamflow, but divergent internal …

Electrokinetics in the Earth
… in the earth sciences, ranging from fluid flow monitoring, to permeability determination, to studying the surface chemistry of rocks and minerals. In this thesis study of frequency-dependent electrokinetics is presented with both theoretical development and experimental verification. The …

Improving a Low-Cost Intravenous Infusion Flow Rate Monitoring Device for Paediatric Care in Humanitarian Healthcare Settings
… can lead to incorrect dosing without adequate monitoring. Capacity for monitoring is limited in humanitarian settings with shortages of medical supplies and personnel, and monitoring being reliant on manual counting or mechanical clamps without safeguards. This particularly poses risks to the …

A Generic BI Application for Real-time Monitoring of Care Processes
… we have investigated the problem of real-time monitoring of care processes, performed a gap analysis of current information system support for it, researched and assessed available technologies, and shown how to most effectively leverage event driven and BI architectures when building …

Application of data-driven technologies for asthma self-management
… symptom scores, sometimes supplemented by peak flow measurements. Keeping track of relief inhaler usage can also help measure asthma control. However, patients may regard this level of monitoring as tedious because it involves high levels of active engagement on their part. Machine learning and …
