The global market for the wastewater treatment industry has been compelled to devise new concepts due to several factors. Currently, approximately 80% of untreated wastewater is discharged worldwide. The conventional technology for municipal solid waste treatment, which has been in use for over a century, is only partially effective in terms of...

Banerjee, I. (author)
In a dynamic or disruptive situation, such as disasters, a fully mobile and decentralized infrastructure-less network seems to be a viable option for communication. Citizens are confronted with challenges such as complicated deployment of these networks, resource-constrained mobile phones and mobility. This requires communication networks to...

Gosztonyi, S. (author)
Adaptive façades are designed to actively regulate the exchange of material and energy flows and thus improve the balance between comfort and energy consumption. However, their technical complexity leads to higher development efforts, maintenance and costs, and ultimately fewer implementations. <br/>Embedded adaptive functions could be an...

Railways in Europe need to reduce CO<sub>2</sub> emissions and energy usage to contribute to sustainability. One of the measures that railway undertakings can apply with low investment cost and both high reductions in CO<sub>2</sub> emission and energy consumption, is energy-efficient train trajectory optimization. Another efficient measure is...

Çelik, M. (author)
Steel is an indispensable material for the sustainable maintenance and progress of modern civilization. Its versatility in terms of mechanical and thermal characteristics, corrosion resistance, raw material availability, energy consumption and recyclability provides a clear advantage in a fast-changing technological landscape. In order to adapt...

In speech processing applications, e.g., speech recognition, hearing aids (HAs), video conferencing, and human-computer interaction, speech enhancement or noise reduction is an essential front-end task, as the recorded speech signals are inevitably corrupted by interference, including coherent/incoherent noise and reverberation. Traditional...

Prieto Hoces, A.I. (author)
Increasing cooling demands in the built environment present an important and complex challenge for the design of sustainable buildings and cities. Even though the first course of action should always aim to reduce energy consumption through saving measures and passive design; these are often not enough to avoid mechanical equipment altogether,...

Worldwide, buildings consume a large part of the total energy delivered. In the context of all the end-use sectors, buildings represent the largest sector with 39% of the total final energy consumption, followed by transport in the EU (European Union ). Policy targets and regulations are in force at the EU level to ensure the energy efficiency...

Even though rail is more energy efficient than most other transport modes, the enhancement of energy efficiency is an important issue for railways to reduce their contributions to climate change further as well as to save costs and enlarge competition advantages involved. This thesis is motivated by the challenges in improving energy efficiency...

Zhou, H. (author)
The research presented in this thesis focuses on the use of hydrate slurries in the air conditioning and refrigeration areas. Both experimental and mathematical methods have been used. Hydrate slurries have been suggested as promising cold storage materials that can be used in air conditioning systems due to their high latent heat (193 kJ/kg and...

Energy consumption reduction is one of the priorities of metro operators, due to financial cost and environmental impact. The new signalling system Communications- Based Train Control (CBTC) is being installed in new and upgraded metro lines to increase transportation capacity. But its continuous communication feature also permits to improve the...

Xin, J. (author)
For enhancing the performance of automated container terminals, this PhD thesis focuses on improving energy efficiency and implementing more autonomous equipment (e.g., free-ranging AGVs) at the operational level. On the one hand, due to the increased energy price and environmental stress, energy efficiency needs to be improved. On the other...

In most types of networks (e.g., optical or transportation networks), finding one or more best paths from a source to a destination, is one of the biggest concerns of network users and providers. This process is known as routing. The routing problems differ accordingly depending on different application scenarios with their respective routing...

De Lange, M.F. (author)
A novel class of materials, i.e. Metal-Organic Frameworks (MOFs), has successfully been developed that is extremely suited for application in heat pumps and chillers. They have a superior performance over commercial sorbents and may potentially contribute to considerable energy savings worldwide. Globally about 33 % of the energy consumption is...

Taleghani, M. (author)
The urban heat island (UHI) phenomenon and the dependency of buildings on fossil fuels were the two main issues that formed this dissertation. UHI results in higher air temperatures in dense urban areas compared with their suburbs and rural surroundings. This phenomenon affects human health through thermal discomfort and air pollution....
