Pilots are an important asset in the operations of airlines, as with insufficient pilots, an airline cannot operate the planned schedule. The long-term crew planning problem aims to optimally plan the supply and demand for pilots as well as methods and strategies for closing the gap between these. The demand is determined by the number of pilots...

In April 2018, a graduation project in the field of architecture was concluded. The project entailed the design of a temporary community centre in the earthquake-damaged historic town centre of L’Aquila, Italy. The underlying social concept was focused on participation of the local population in the construction of the community centre. The...

The air cargo industry is a challenging environment due to the high competition between the stakeholders involved. This demands, as example, high efficiency from cargo airlines. Efficiency can be ensured by designing loading strategies that fully exploit the available cargo volume. Unknowns in the booking dimensions and flight information make...

Current Ballistic Missile (BM) defence systems intercept an incoming threat in its terminal phase, and to some extend during its coast phase. During the boost phase of a BM, the initial velocity of the BM is low and the hot exhaust plume is easy to spot for infrared sensors, which provides a good opportunity for interception. To do so, the...

Calibration of groundwater models can be done manually by comparing the measured and computed groundwater heads or automatically using algorithms which do the work for you. Modules for this purpose are included in or linked externally to traditional groundwater modelling software and used. One such module PEST (Parameter ESTimation) uses the...

EU carbon emission targets related to climate change has set in motion a process of transition towards an environmentally clean and sustainable power system. A central focus on this process is the transition from fossil fuel based energy sources to clean Renewable Energy Sources (RES). However, the intermittency of RES (e.g. solar and wind)...

Ever since the late seventies great engineering effort has gone into increasing the fuel efficiency and reduction of the noise profile of aircraft. A concept that has been explored is the wingtip-mounted (pusher) propeller. In all wings energy is lost due to the lift-induced vortex at the wingtip. Wingtip-mounted pusher propellers can recover...

In an operational airline environment, disturbances to the planned flight schedule cannot be avoided. In the case of crew absences, airlines can employ reserve crews to cover open positions in crew schedules. The airline reserve crew pairing problem is concerned with the determination of optimal airline reserve crew patterns, which are defined...

The volatile production of renewable energy sources is often considered a key issue in future sustainable energy systems. Drawing on microgrid research, we argue that the potential synergy between microgrid energy management and provision of flexibility services to the wider grid could be further explored. In addition, the trade-off between cost...

In this project we aimed to create a post-trading day safeguard system that allows for the identification of bugs in the primary and secondary risk control systems at Optiver. These systems are needed to prevent undesirable exposure to the market from happening, and to ensure that they know exactly what this exposure is. The amount of input data...

Additive manufacturing and 3D printing are rapidly developing digital fabrication techniques. After the first steps in printing of metals and plastics have been made, research from various groups around the world is now also focusing on printing in concrete and moving to larger scales. Using this technique it will be possible to create...

The idea for Geometry matching by multi-agent systems as a subject originates at a previous course, where the J. Sturkenboom & author came up with an idea to use the material of old boat hulls as facade elements to provide a solution to an environmental problem. The approach then was rather practical, whereas the approach within this thesis...

The offshore wind industry is rapidly growing, and so is the competition in this market. Normally, offshore installation companies receive a subsidy for building offshore wind farms, but due to multiple companies bidding to install for lower and lower subsidies, the point where wind farms are installed without subsidy has been reached. Therefore...

This thesis research focusses on the development of a reliable and efficient 3D calculation model of an existing high-rise, reinforced concrete building in the Groningen area, in order to analyse the dynamic behaviour of the existing and subsequently retrofitted main bearing structure of this high-rise building. The assessment of the existing...

Missions to Near-Earth Objects (NEOs) are a growing trend in spaceflight. The interest for such bodies is not only justified by the threat that they represent for the Earth, but also because they are potential sources of extra-terrestrial materials, provide windows to the past of the Solar System and to planetary formation, and offer a good...

A strategy for completing a dredging project is called a working method. The goal of a tender study is to find an optimal working method for a specific project. To find the optimal working method, the full range of possible solutions should be investigated. However, the available resources during a tender study are often limited and trends in...

In this thesis we look at the most cost-<br/>effective trajectory for power limited rockets, i.e. the trajectory which costs the least amount of propellant. First some background information as well as the differences between thrust limited and power limited rockets will be discussed. Then the optimal trajectory for thrust limited rockets, the...

Many robotic systems rely on laser ranging sensors to navigate and map their environment. As robots are getting more advanced, smaller and cheaper, their sensors need to decrease in size and cost, while increasing their reliability and accuracy. Current laser-based sensors have difficulty to meet these properties. They are either large,...

Narrowband Internet-of-Things (NB-IoT), recently introduced by 3GPP, is a relevant Radio Access Technology (RAT) solution for deployment within smart grids, the electricity grids of the future, due to the need to provide low-cost connectivity to a large number of smart meters installed in households. Outage Restoration and Management (ORM), a...

At large-scale events, the large inflow of visitors travelling by car often causes queues on the roads in the direct surroundings of the event. These queues can spill back to the main road network, where through traffic is driving as well: this through traffic will be hindered by the congestion, while those travellers don’t have the event venue...
