Separation and selective production of branched paraffins are among the most important and still challenging processes in the oil and gas industry. Addition of branched hydrocarbons can increase the octane number of a fuel without causing additional environmental concerns. Conversion of linear hydrocarbons into branched ones also improves the...

The challenge of global warming caused by the emission of greenhouse gases has led to the desire for mitigating climate change by exploring the use of alternative sources of energy to reduce the use of traditional fossil fuels. In this context, supercritical fluids play an important role due to their use in various technologies and processes...

Research of the ageing mechanisms in the Netherlands is crucial to deal with ageing infrastructure and the growing pressure on and lack of natural resources. The use of porous asphalt incurs the additional costs because of the shorter service life and the more expensive maintenance required. On the other hand, the Dutch road engineering...

This paper investigates the potential use of natural ventilation strategies to reduce the energy demand for cooling and mechanical ventilation for high-rise buildings in summer. A 21-storey office building was selected to represent a mechanically ventilated high-rise design in temperate climates. Six natural ventilation scenarios were developed...

This thesis demonstrates that heterogeneous spatio-temporal demand profiles are required for a realistic representation of urban energy systems. This is needed to prepare them for the energy transition. Therefore, existing and future urban energy system models should be expanded with more detailed spatio-temporal local demand data that account...

Fixed bed arrangements find wide applications, particularly in reaction engineering, where they are employed as multi-tubular catalytic reactors for the transformation of reactants into desired products. The importance of such complicated reactors can be realized by their extensive applications as the process workhorse in various industries, e.g...

Various types of complex biomechanical models have been published in the literature to better understand processes related to inflicted head injury by shaking trauma (IHI-ST) in infants. In this systematic review, a comprehensive overview of these models is provided. A systematic review was performed in MEDLINE and Scopus for articles using...

Volgens voorlopige cijfers hebben gemeenten in 2018 een positief resultaat van één en een kwart miljard euro gerealiseerd op grondexploitaties. Dit saldo bestaat voor een kwart miljard euro uit een positief resultaat op investeringen in fysieke bedrijfsinfrastructuur en voor een miljard euro uit grondexploitaties voor woningbouw. Dit resultaat...

Microprocessors are used in an expanding range of applications from small embedded system devices to supercomputers and mainframes. Moreover, embedded microprocessor based systems became essential in modern societies. Depending on the application domain, embedded systems have to satisfy different constraints. The major challenges today are cost,...

The ability to steer carbon fibre tapes, varying the tow angle, can widen the designs possibilities of cylindrical shells that are one of the main components of aerospace structures. This research presents experimental and numerical investigation of two carbon fibre reinforced plastic cylindrical shells – a cylinder with conventional layup made...

Composite materials are finding increasing application, for example in commercial aircraft. Traditionally fiber angles are restricted to 0°,±45° and 90°. The current work exploits the possibility of using multiple ’non-conventional’ laminates where either fiber steering (‘variable stiffness’), ply drops (‘variable thickness’), or a...

Safety management systems (SMSs) have gained importance since the 1970s and changed focus from individual management activities to more systematic frameworks. The methods, techniques and tools used in them also became more and more sophisticated. However, from the perspectives of the researcher, company, auditor, government and (safety...

For the reliable estimation of velocity vector fields by means of particle image velocimetry (PIV), the cross-correlation functions calculated from the signal within each interrogation window must feature a distinct peak that represents the average shift of the particle image ensemble. A high valid detection probability (VDP) of the correct...

Rare earth elements (REEs), along with other metals, will play a pivotal role in the transition towards a low-carbon economy. Primary mining of REEs consists of multiple steps, is energy intensive and has an adverse environmental impact. Thus, the current scenario of “use and throw” of REEs after a single use in a product is untenable....

The work presented in this thesis will open a pathway towards the design of crosslinkable hyperbranched poly(aryetherketone)s (HBPAEKs). In addition to addressing the chemistry, crosslinking characteristics and (thermo)mechanical properties we will demonstrate that crosslinked HBPAEKs are excellent candidates for membrane-based gas separation...

Remotely controlled subsea vehicles are frequently used for oil and gas applications. A potential future application requiring remote controlled vehicles is deep-sea mining. At the envisioned water depths beyond 1500m, rare minerals are accessible without deep excavation. However, the extreme hyperbaric conditions (i.e. high pressure), limited...
