The skyline operator has been proposed to bridge the gap between traditional and multimedia database systems by finding the optimal objects according to the notion of Pareto dominance. According to the notion of Pareto dominance an object dominates another if it is better in one attribute and equal in all others. Skyline sets end up being pretty...

The acute obstetrics (AO) sector in the Netherlands faces two challenges. The increasing difficulty to find personnel and the closing down of several locations have put a major pressure on the existing AO locations. This has led to questions about the quality of the spatial distribution. The measures currently in place are based the travel time...

To realise more sustainable industrial ground floors the implementation of alkali-activated concrete is considered for jointless elastically supported ground floors. Such floors are realised with large areas without dilations, the shrinkage reduction is therefore restrained causing cracks to arise at the top surface of the floor. The control of...

This thesis focuses on the field of Job Recommendation. Particularly, we focus on using implicit preferences exhibited by the job seeker in interactions with a web platform to propose an improved ranking algorithm for a job recommendation platform called Magnet.me. We also study evaluation of relevance, and evaluation of recommendation sorting...

In times when there is more and more focus on environmental impact, all aspects must be taken into account. Expanded polystyrene (EPS) is easy and cheap to produce and has lots of applications because of its properties. These properties however, also make it a hard material to recycle. This paper focuses on a rich mathematical model for the...

Inter-Autonomous System (AS) route monitoring is the process of collecting the inter-AS routing information. This information flows on the Internet in the form of BGP UPDATE messages, and the BGP data are the messages obtained by the monitors. Existing methods of monitor placement rely on the network topology which provides inadequate visibility...

With the rise of globalisation, countries have become more connected financially and global cross-border investment flows have become more common. FDI is an important form of cross-border flow which is responsible for the spread of technology across countries and is the main source of external finance for emerging countries. In the last two...

Worldwide population growth, water scarcity, and climate change contribute to an urgent need for alternative water sources for irrigation water, industry water, and, in some countries even, drinking water. The implementation of municipal sewage reclamation is an upcoming trend in water treatment. The use of municipal sewage has the advantage of...

The environmental control system is an essential system on all modern aircraft and is the largest consumer of secondary power. System power consumption is potentially reduced by using electric compressors to feed the system, instead of bleed air. The aim of this research is to provide a first order estimate of the potential benefits on mission...

Preventing solidification cracking is an essential prerequisite for the safety of a welded structure. An undetected solidification crack has the potential to cause premature failure during service. Two conditions generated by a weld thermal cycle are responsible for the initiation of solidification cracks. The first is the presence of excessive...

Developing intelligent decision making systems in the real world requires planning algorithms which are able to deal with sources of uncertainty and constraints. An example can be found in smart distribution grids, in which planning can be used to decide when electric vehicles charge their batteries, such that the capacity limits of lines are...

Buildings don’t use energy: People do. Do highly efficient homes really save energy? Counter-intuitively, dwellings that use less energy have low energy efficiency, and those with higher energy consumption have higher efficiency. Moreover, even accurate building energy simulation for multiple buildings could not predict the actual energy...

The wide adoption of composite structures in the aerospace industry asks for reliable numerical methods to account for the effects of damage, among which delamination. Cohesive elements (CEs) are a versatile and physically representative way of reproducing delamination, but, using their standard form, at least 3 elements are required in the...

Implantable Medical Devices (IMDs) could fulfill many different functions in the human body. Batteries have always been the main power source of these devices. Batteries have some drawbacks, the biggest one being the replacement of IMDs with fully discharged batteries. In this thesis a wireless power transfer system, with a receiving power...

Power consumed by any equipment connected to the grid must be regulated to facilitate the reliable and efficient operation of the grid and for smooth equipment operation of other consumers. Power factor is one of the major power quality measurement tool. All the electrical equipment connected to the grid must comply with the power factor limits...

A major cause for voiding dysfunction is the inability to relax the urethral sphincter. KiloHertz Frequency Alternating Current (KHFAC) stimulation can block signals that are travelling through the body; applying this type of stimulation at the pudendal nerve could inhibit the pulses that lead to contraction of the urethral sphincter, and...

Teleoperation is by nature a deprivation of the senses, which can pose a handicap when operating in an unknown and even dynamic en- vironment. Noticing moving obstacles in such a situation can prove to be quite difficult and the UAV runs the risk of colliding with them. Previous work designed a shared control haptic interface based on the...

Operational towing is a taxiing strategy to reduce the fuel consumption during the taxiing phase of a flight, which decreases the cost and environmental impact of taxiing. Currently, no operational electric towing systems are available that are fully electric, independent from the APU and are capable of towing both narrow- and wide-bodied...

Reukema is the biggest non-ferrous trader in the Netherlands. They want to investigate the possibility of sorting aluminium in a robotic system. Aluminium is one of the most used materials worldwide. Demands for aluminium are ever increasing. Recycling scrap is needed to keep up with the demand. An important step in the recycling process is the...

Multi-Agent Systems, often referred to a network of loosely connected autonomous units, are widely used to model the dynamics of crowds, vehicles, robots and swarms in traffic management, biological environment, distributed control and communication technologies. Recently, the study of multi-agent systems is rapidly growing due to the beneficial...
