Use of confidence curves to represent uncertainty in hydro-meteorological time series analysis

Climate change is incompatible with the assumption of stationarity. This has lead to a sharp increase in the detection and study of nonstationarity in hydro-meteorological processes. Most hydro-meteorological processes are still analyzed by studying time series of observations. From the perspective of statistical characteristics, a stationary...

Supporting Adaptive Delta Management: Systematic Exploration of Community Livelihood Adaptation as Uncertainty

Long-term planning in urbanizing deltas has to deal with deep uncertainties in socio-economic development and climate change. Adaptive Delta Management (ADM) has been developed as an approach that acknowledges these and similar uncertainties. The Bangladesh Delta Plan 2100 has, in principle, adopted the ADM approach, and it recognizes general...

3D Path Planning for UAVs in Dynamic Environments in the Presence of Uncertainties

Unmanned Aerial Vehicles (UAVs) are being integrated into all spheres of life, for a wide range of application in civil, commercial and military applications in both indoor and outdoor environments. UAV onboard intelligence is a paramount requirement in the realisation of UAV Traffic Management System (UTM) and Air Traffic Management (ATM)...

Bridging PIV spatial and temporal resolution using governing equations and development of the coaxial volumetric velocimeter

A series of techniques is proposed for volumetric air flow measurements that are based upon the principles of particle image velocimetry (PIV). The proposed techniques fall in two categories; part 1 of this dissertation considers measurement data processing using constitutive laws and part 2 focuses on development of a coaxial volumetric flow...

Processing Risk In Asset Management: Exploring The Boundaries Of Risk Based Optimization Under Uncertainty For An Energy Infrastructure Asset Manager

In the liberalized energy market Distribution Network Operators (DNOs) are confronted with income reductions by the regulator. The common response to this challenge is the implementation of asset management, which can be regarded as systematically applying Cost Benefit Analysis (CBA) to the risks in the networks. In short, this is Risk Based...

Optimal Control of Water Systems Under Forecast Uncertainty: Robust, Proactive, and Integrated

Water systems consist of natural and man-made objects serving multiple essential purposes. They are affected by many types of meteorological disturbances. In order to deal with these disturbances and to serve the desired objectives, infrastructures have been built and managed by societies for specific purposes. Given a water system, and its...

Eddy covariance observations of methane and nitrous oxide emissions: Towards more accurate estimates from ecosystems

About 30% of the increased greenhouse gas (GHG) emissions of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) are related to land use changes and agricultural activities. In order to select effective measures, knowledge is required about GHG emissions from these ecosystems and how these emissions are influenced by management and...
