The use of recycled materials is a new tendency in the field of railway engineering. Steel slag aggregates (SSA) are one of the recycled materials derived from the steel industry. The application of SSA in ballasted railway tracks requires mechanical examination. In the present paper, the shear behavior of the ballast layer constructed by SSA...

In this thesis several aspects of PEM fuel cells are discussed. From an atomic scale, e.g. crystal and electronic structure of a non-noble metal material, e.g. (H)zLiMn2O4 (protonated spinel lithium manganese oxide) for electrocatalysis and its dynamics, to meso-macro scale effects such as those concerning transport resistances at the membrane...

Especially in the car industry, spot and projection resistance welding are commonly used to weld thin sheets of steel and aluminium. Spot welding leaves visible indentations after welding, whereas the company Arplas Systems uses a projection welding method resulting in almost invisible welds. For spot welding, C- and X-type welding machines are...

The on-field performance and lifespan of PV modules are affected by the interaction of numerous parameters, among which temperature, strain, and humidity. Among these parameters, only temperature is occasionally measured in PV installations, and such monitoring is often external to the module. This limits its use and does not provide accurate...

With increasing pressure on natural water resources, wastewater is gradually being considered as a potential source for potable water. Current WWTPs are designed for the removal of parameters like solids, nutrients, organic matter, and pathogens. For achieving a high-quality effluent, that enables reuse, it is important to also address the...

Landslides pose a risks to the communities settled in their vicinity. They pose a threat to human lives and significant economical damage to the affected communities. As the scientific community agrees that the climate change will further increase the risks associated with landslides, it is important to develop a reliable, cost effective and...

Stimulated by the energy efficiency indices introduced by the International Maritime Organization, the increased attention for the environment as well as economical pressures emphasize the relevance of accurate resistance estimation for ships. This leads to a particular interest for added resistance in waves, a resistance component that is...

As antibiotics now save millions of human and animal lives annually, the World Health Organisation (WHO, 2019) declared Antibiotic Resistance (AR) as the number five most dangerous risk to global health. Several researchers mention WWTPs to be an important source for AR as the growth of bacteria is stimulated in an environment with a selective...

Dutch cities are both expanding and densifying, corresponding to a global<br/>trend in which people increasingly tend to live in cities. Urban densification<br/>implicates the development of new buildings and redevelopment of part of the<br/>existing building stock, to meet the aims of future cities and their populations.<br/>These alterations...

Over the last few years, the United States has experienced a shortage of fly ash and slag that consequently created a need for an alternative material that is locally available, sustainable, and provides desirable concrete properties. Recent studies have shown that Ground Glass Pozzolan (GGP) offers favorable attributes as a supplementary...

Service life of concrete infrastructure is severely compromised because of chloride-induced corrosion and measuring the chloride content is crucial to determine the remaining service life. DuraCrete provides a chloride ingress model based on Fick’s 2nd law. Although the diffusion coefficient is modelled as a time-dependent variable, the...

In the present study, a proprietary 0.2 tonne/h Dusty Cloud Separation (DCS) technology prototype by Value Ash Technologies NV (Belgium) was used to obtain ultra-fine fly ash as a novel by-product. Two types of Class F fly ash were used: separated fly ash (FA1) with particle size < 9.3 μm and ultra-fine fly ash (FA2) < 4.6 μm as sub-fraction of...

The time dependency of the chloride diffusion coefficient, the so-called ageing coefficient, of fly ash concrete has been investigated. The effect of origin of the fly ash as well as the origin and strength level of the cement combined with the fly ash, has been determined. Results obtained using the RCM-method on samples aged up to 5 years...

The purpose of this study is to clarify the performance of cement hardenings containing clinkers which are utilized as aggregate by evaluating the compressive strength and chloride ion penetration resistance of the mortars. Here, the fine aggregate used in this study were the ordinary Portland cement clinker and the clinker with more waste as an...

Reducing dredging activities in the harbors brings benefits both economically and environmentally. However, this means that ships may have to sail very close to or even through the mud layer on the seabed, with possible effects on ships’ resistance and manoeuvrability. This study has made a step in understanding these effects on ships’...

The pressure to reduce emissions in the sector of inland shipping is increasing. Especially considering emissions of environmental pollutants, the increasing pressure gives rise to the question how to get insight into emissions distributions along an inland waterway network. In this research, a bottom-up method is developed that is able to map...

This paper proposes a socio-technical agent-based model developed to increase the understanding of decision-making in an airline operational control center (AOCC). In this model human decision-makers, a Decision Support Tool, and technical systems are included. The selected case study encompasses the<br/>unexpected diversion of a flight from...

Liquid metal embrittlement (LME) is a problem encountered in the resistance spot welding joining process of advanced high-strength steels in the automotive industry. Its occurrence reduces the mechanical performance of welds. The nature of resistance spot welding prevents in-situ characterisation of thermo-mechanical conditions causing LME....

Since the transfer of sovereignty over Hong Kong in 1997, the opportunities for political conversation are diminishing, censorship has been gradually imposed on different means of mass media. In the face of the gradual loss of freedoms, the people of Hong Kong have demonstrated an atmosphere of solidarity through social movements and physical...

The North East of England has historically prided itself on a strong sense of self, with an identity rooted in a unique culture and a proud industrial past. In 2020, the UK left the EU and a transition period began in which the terms of its future will be set, and with an increasingly independent Scotland to the north, it faces further...
