Electricity grids worldwide are experiencing increased peak demands and decreasing simultaneity due to higher shares of Renewable Energy Sources (RES). It is expected that many grids will soon reach their limits. One solution to mitigate these issues is exploiting flexibility in e.g. electric vehicles. In this work, a shrinking horizon model...

Earthquake prediction has raised many concerns nowadays, due to the massive loss caused by earthquakes, as well as the significance of accurate forecasting. Lots of trials have been investigated and experimented but few achieved satisfying results on short-term prediction (i.e., usually those earthquakes that will happen in three months). It is...

Observations of wind and ocean surface velocity vectors by along-track interferometry (ATI) with the synthetic aperture radar (SAR) are not only important for direct applications but also to increase understandings of ocean upper layer mixing, air-ocean interactions, and mapping submesoscale (1-10 km) structures. An experimental bidirectional...

On the railway line between Zutphen and Hengelo in the Netherlands, rolling contact fatigue (RCF) defects are found at the surface of the rail. RCF is a known hazard to the safe operation of railways, the cracks can cause transverse rail fracture, which may result in derailment. Contrary to convention, the traffic on this particular railway is...

In adaptive platooning strategies proposed in literature to handle uncertain and nonidentical uncertain vehicle dynamics (uncertain heterogeneous platoons) two aspects requiring proper design are neglected: bidirectional interaction among vehicles which might lead to loss of string stability, and engine saturation constraints which might lead...

The urgent transition to other forms of energy production, delivery and consumption has induced investments in new technologies such as renewable energy sources, storage units and demand response programs. Investments in these assets represent long-term commitments (e.g. 40 years ahead) from civil society, governmental institutions and capital...

In the past years electric cars have been rapidly taking market share in the automotive industry. Stimulated by their sustainable image and due to large investments in the charging infrastructure, the electric automobile has gained popularity in the field of research. Many papers are written on a variety of power converters inside the cars to...

Over the last decade the share of electric vehicles has increased and will continue to increase in the future in order to reduce the carbon footprint by transportation. However, the battery voltage is not standardised and can differ per car model. To reduce the charging time, a high power converter is preferred. Moreover, in order to utilise the...

This paper aims to present a novel switched-capacitor multi-level inverter. The presented structure generates a staircase near sinusoidal AC voltage by using a single DC source and a few capacitors to step-up the input voltage. The nearest level control (NLC) strategy is used to control the operation of the converter. These switching states...

Since the power transfer efficiency in inductive power transfer (IPT) systems is directly related to the coupling of the transformer, coil misalignment can drastically decrease the efficiency. In this paper a misalignment tolerant control scheme is proposed which tracks the maximum power transfer efficiency point under misalignment. It does this...

Triple active bridge (TAB) as an isolated multiport converter is a promising integrated energy system for smart grids or electric vehicles. This article aims to derive and analyze zero voltage switching (ZVS) regions of TAB, in which both switching losses are reduced, and electromagnetic interference issues are mitigated. In the proposed...

Rotating ones body is a strategy pedestrians commonly use to avoid collisions. Even though this behaviour impacts capacity heavily, this rotation behaviour is seldomly studied. This research aims to increase insight into rotation behaviour of pedestrians in high density bidirectional and crossing flows. Based on data from the CrowdLimits...

The growth of distributed Renewable Energy share in the total electricity production as wells as technological advancements in power electronics and increase of DC loads, point towards the development of the DC microgrid (DCMG) concept as a valid model for future energy systems especially for operations and locations where the existing grid...

Within this research parcel behaviour over a bidirectional sorter is optimized to increase efficiency. Currently, influence of parcel properties on the sortation behaviour is unknown and equipment settings are set by experience rather than objective information. To gain insight in the behaviour first, a simulation model has been developed and...

Focusing on real life commercial applications, this thesis presents the theoretical and practical control requirements of an application board, which exploits flexible bidirectional DC-DC converters, to power up a unit of multi USB type-C ports. Emphasis is given in the power management between the connected devices since the power flow is...

Artificial elbow modules are used in orthoses and prostheses, whereby orthoses correct, align and support the body with skeletal or neuromuscular impairments [1]. Instead, prostheses replace missing body parts and compensate for lost functions [1]. However, most designs do not allow the natural arm swing based on their transmission design or the...

The use of 3D city models has increased the last decades due to the evolution of technology. Their use is related to the need for solutions on issues that correspond to the building environment. Modelling aspects, like geometric, semantic information and topology are necessary, in order to provide an integrated result of spatial analysis. The...
