Saltwater intrusion is a crucial issue in estuaries. The spread of salinity is described by the dispersion coefficient. A purely empirical equation which links the effective tidal average dispersion to the freshwater discharge was developed by Van der Burgh [1972]. Combining it with the salt balance equation, Savenije [1986] derived a one...

With the growth of global population, the big cities become increasingly crowded. It is not rare to see large crowds in public transportations and events with masses of visitors, such as music festivals and football matches. The question “How to deal with crowds” is receiving attention, both from academia and practical crowd management.
This...

Growing importance of hydrogels in various areas of human life has led to increasing need in controlling their properties, which is generally achieved by adjusting hydrogels shape and microstructure. Even though standard microfabrication and microstructuring techniques can be currently applied in hydrogel research, the variety of properties of...

Wheels are critical components of trains, and their conditions should be therefore monitored.Wheel defects change the wheel-rail contact and cause high impact forces thatare damaging for tracks and trains. Wheel defects can also cause unexpected failuresthat reduce the availability and reliability of the railway system. Several monitoring...

Artificial illumination has had profound and far-reaching impacts on the development, use, and perceptions of urban nights, and has brought with it many benefits. However, in recent years its adverse costs and effects – commonly referred to as light pollution – have emerged as a topic of concern. Nighttime lighting uses enormous amounts of...

The realization of interfaces between different transition metal oxides has heralded a new era of materials and physics research. Notably, it enabled a uniquely diverse set of coexisting physical properties to be combined with an ever-increasing degree of experimental control. The primary focus of this thesis is the celebrated interface between...

Although being a crucial step in structural design of laminated composites, prediction of their long-term mechanical performance remains a challenging task for which no comprehensive and reliable solution is currently available. Nevertheless, structures such as wind turbine blades, of which laminated composites constitute the main load bearing...

The aim of this project was the development of the scientific basis for methodologies that enable the production of renewable sustainable cement (i.e. BioCement) based on ashes derived from the conversion of biomass residues. Within this project, biomass ash and derived products were developed at the laboratory scale, and their functionality was...

The conventional development of a new automobile starts with a first proportional model. In this model, the exterior geometry of a car can be distinguished into vehicle, power train portfolio, market requests, safety requirements, and design target. The interior design results from the proportional model with specific characteristics, such as...

Nearly 200 parties signed and committed to the Paris agreement in 2017, which comprises the long-term goal to keep the average global temperature increase well below 2 degrees above pre-industrial levels. Virtually all possible scenarios drafted to reach this goal include a strongly increased use of biofuels for transport by land, sea and air....

Scanning radars are promising sensors for atmospheric remote sensing, giving potential to retrieve parameters that characterize the local air dynamics during rain. For the observation of air motion, radars are relying on the backscatter of particles, which can, for example, be raindrops or insects. To measure wind vectors and turbulence...

With the growth of decentralized, off-grid, and distributed renewable energy
systems across the globe, an arena for energy exchanges between households
is opening up. As compared to traditional ‘centralized’ energy supply systems,
in these emerging energy systems households are imagined to acquire agency
by having choice and...

The building sector currently accounts for approximately one-third of the global demand for energy, and one-fifth of all energy-related greenhouse gas emissions (GHG). The development and adoption of energy-efficient technologies in this sector is therefore a key element towards efforts for the mitigation of climate change. In particular,...

Electricity consumption is increasing on a global level. In 2017, non-renewable energy sources such as crude oil, natural gas and coal provided 76% of the required energy, while 24% came from renewable sources such as hydro, wind and solar. Non-renewable sources are finite because they do not replenish rapidly enough relative to the rate at...

Port logistics (PL) can be defined as the process of planning, implementing and controlling the flow of goods and information between the sea and inland via ports and the other way around. PL systems concern the development of functions to support activities including sea side and land side transportation, cargo storage, order processing, and...

In this dissertation, structural wind turbine blade layouts are presented that are suitable for 10MW and 20MW wind turbine blades. This has been accomplished by using a medium fidelity static aeroelastic model embedded in an optimisation framework. The structural solutions are the result of a stiffness optimisation where the blade mass is...

In nature, solar energy conversion occurs with a process called photosynthesis. Although the overall energy efficiency of the storage of the energy of sunlight into biomass is low, the individual photophysical processes that occur have a high quantum yield. In the latter sense, natural photosynthesis can serve as a valuable inspiration for the...

Surface heat fluxes (latent and sensible heat over the land surface) play a key role in the land-atmosphere interaction, and their spatial pattern as well as temporal evolution are vital to the terrestrial water cycle and surface energy balance. Ideally, we want to have accurate estimates of spatially distributed and temporally continuous fluxes...
