Estimation problems in the presence of deterministic linear nuisance parameters arise in a variety of fields. To cope with those, three common methods are widely considered: (1) jointly estimating the parameters of interest and the nuisance parameters; (2) projecting out the nuisance parameters; (3) selecting a reference and then taking...

Early detection of traffic anomalies in networks increases the probability of effective intervention/mitigation actions, thereby improving the stability of system function. Centralized methods of anomaly detection are subject to inherent constraints: (1) they create a communication burden on the system, (2) they impose a delay in detection...

In this paper two methodologies are investigated that contribute to better assessment of risks related to extreme rainfall events. Firstly, one-parameter bivariate copulas are used to analyze rain gauge data in the Netherlands. Out of three models considered, the Gumbel copula, which indicates upper tail dependence, represents the data most...

Stochastic descriptions and simulations of oceanographic variables are essential for coastal and marine engineering applications. In the past decade, copula-based approaches have become increasingly popular for estimating the multivariate distribution of some variables at the peak of a storm along with its duration. The modeling of the storm...

Verification of the explicit finite element (FE) model with realistic wheel-rail profiles against the CONTACT model, which has not been sufficiently discussed, is performed by comparing the resulting shear stress, slip-adhesion area, etc., obtained from the two models. The follow-up studies using the verified FE model on the influence of the...

Multifunctional flood defenses protect areas against flooding, but
serve other functions as well. Although these types of defenses
can be seen almost everywhere, they pose special technical and
governance challenges.

This book is about a unique interdisciplinary research program
developed to tackle some of the issues...

This paper presents a condition-based treatment methodology for a type of rail surface defect called squat. The proposed methodology is based on a set of robust and predictive fuzzy key performance indicators. A fuzzy Takagi-Sugeno interval model is used to predict squat evolution for different scenarios over a time horizon. Models including...

Surface texture is important for contact mechanical and tribological phenomena such as the contact area and friction. In this research, three different types of geometrical microstructures were designed and fabricated by pulsed laser surface texturing as semi-symmetric (grooved channel), asymmetric fractal (Hilbert curve), and symmetric...

The loads that are used for the assessment of existing reinforced concrete slab bridges are the self-weight, superimposed loads, and distributed and concentrated live loads. As such, the shear capacity of reinforced concrete slabs under a combination of distributed and concentrated live loads is a topic of practical relevance. For slabs...

In this work, a glass/epoxy material system applied in wind turbine blades was used to evaluate degradation processes induced by water ingression. Composite and neat epoxy specimens were conditioned in demineralised water at 50 °C for 4800 h and tested quasi-statically and in fatigue. Comparing results from mechanical tests in composite...

Stated choice surveys have been used for several decades to estimate preferences of agents using choice models, and are widely applied in the transportation domain. Different types of experimental designs that underlie such surveys have been used in practice. In unlabelled experiments, where all alternatives are described by the same generic...

This paper deals with the Airline Delay Management Problem (ADMP), which can be described as the task of dealing with daily airline operational delays and deciding whether to delay subsequent flights at a hub airport or to have them departing on time. An innovative integer linear programming approach is presented to the capacitated case of...

Ongoing eutrophication frequently causes toxic phytoplankton blooms. This induces huge worldwide challenges for drinking water quality, food security and public health. Of crucial importance in avoiding and reducing blooms is to determine the maximum nutrient load ecosystems can absorb, while remaining in a good ecological state. These so...

In order to attain a truly sustainable society it is necessary for people to make ‘the sustainable choice’ in daily life, business and governance. Instrumental in increasing the awareness and understanding about sustainability issues and improving people's behaviour regarding sustainability issues is sustainability education. However,...

Turbulence is implicitly present or explicitly desired in many natural and industrial
processes, such as, flow over solid surfaces, cloud formation, pollination, combustion,
and chemical mixing. Hence, a better understanding of turbulence can aid in fuel saving
by reducing drag in the case of flow over solid surfaces, namely, cars,...

Most modern software systems can be adjusted to satisfy sets of conflicting requirements issued by different groups of users, based on their intended usage or execution context. For systems where configurations are a core concern, specific implementation mechanisms are put in place to allow the instantiation of sets of tailored components. Among...

The cost of currently available technologies for CO2 capture should be further reduced to allow for large scale implementation of Carbon Capture and Storage. Solvents for CO2 capture systems with physical absorption are usually selected based on heuristics, engineering expertise and experimental trials. The performance of the separation system...

Loss of aircraft lateral control can be problem, specifically when multi engine propeller aircraft are faced with an engine failure. Another, less frequent phenomena is the loss of lateral control in case of aircraft damage. In this thesis, a method is developed to determine the minimum required aircraft velocity as a function of aircraft state...

This dissertation investigates how to design a pipe belt conveyor system in a more effective way, considering two aspects: to ensure conveyor belt has sufficient bending stiffness to form an enclosed pipe shape without a contact loss with the idler rolls; and to reduce energy consumption of the system from the indentation rolling resistance. doctoral thesis 2017
