Patients with 1p/19q co-deleted low grade glioma (LGGs) have better prognosis and react better to certain treatments than patients with intact 1p/19q LGG. Currently, information about the 1p/19q co-deletion status is obtained by means of an invasive procedure called biopsy. As an alternative, non-invasive techniques to extract this information...

In this day and age, failure of railway switches is managed using preventive and corrective maintenance, not predictive maintenance. These maintenance methods may allow for failure, where such a feailure could have been predicted. To combat this issue, this paper proposes a real-time predictive maintenance framework, which can identify the...

One of the most promising ideas in autonomous vehicle control systems is letting the vehicle drive autonomously outside the normal, linear, operating region and letting it "drift". By doing so, the maneuverability of the vehicle could be enhanced. To enable systems that can control this behaviour, estimation of certain vehicle states is needed...

Collaborative search, where the activities of multiple users are combined to satisfy their information need, is an effective tool to to handle complex search tasks. People search collaboratively in groups of varying sizes. Various collaborative search systems have been studied in previous work, but they only investigate a fixed group size....

Lagoons are connected to the sea by the presence of openings along their barriers. These openings, also known as tidal inlets, can either be natural or man-made and they highly determine the hydrodynamics within the lagoon system. Tidal inlet systems are found worldwide, and many of them are difficult to be understood due to their complex...

Neural interface in the form of microelectrodes is used to monitor and treat spinal cord injury and other neurological disorders by the means of recording and stimulation. Despite the apparent result of these electrical interventions, understanding of the mechanism behind neural stimulation is still inadequate. The use of optical monitoring...

Our world is rapidly changing, leading to various technological achievements in diverse areas of expertise. Among the most evolving are autonomous robots, machines and vehicles, enormously extending human capabilities. While this trend became quite familiar for land-based vehicles, innovations in the underwater domain lag behind, mainly due to...

With the growing population and industrial development, there is more stress on natural water resources. Additionally, environmental laws make the disposal of waste streams from industries difficult. In this scenario, it is crucial to treat waste streams to recover water and possibly minerals, for reuse in the industry, reducing the dependency...

Settlement data of the Kiltunnel and the Heinenoordtunnel show that immersed tunnels in the Netherlands have been experiencing much larger settlement than expected when designing the tunnels causing cracks in the concrete and leakages in the joints. Settlements of 8 - 70 mm have been measured at the Kiltunnel and of 7 - 30 mm at the...

The counterfeit market is rapidly expanding into the online realm. Large amounts of fraudulent webshops advertise luxury clothing and fashion accessories, but ship counterfeit products to their customers. Apart from customers, brand owners and domain registries experience a negative impact caused by these fake webshops. Current countermeasures...

A traditional Trombe wall is known as a high thermal-mass wall, situated behind a window of a room and separated by an air cavity. The idea behind using a Trombe wall is that heat, ventilation and comfort can be passively generated by using the ‘free’ energy of the sun. The surface of the wall absorbs solar radiation when the sun shines, stores...

Background: Pressure ulcers are skin and soft tissue wounds that lead to severe patient suffering and considerable financial burden, with the yearly treatment cost estimated at 1.25 billion euro in the Netherlands alone. Research findings suggest posture classification in bed as a promising tool for pressure ulcer prevention, however currently...

In 2018, 1.1 billion people still lacked access to energy services. Most of these people are located in remote areas which are hard to reach, especially with conventional methods of grid extension. Even if the number of people without energy access is decreasing and the number of people gaining access to electricity through renewable sources is...

Jetted radial wells are a relatively new form of hydraulic stimulation for oil and gas wells, where small diameters holes extend radially from a wellbore. This technique for increasing well connectivity could also be applied to geothermal wells. Radials can be freely placed along a backbone well, making the design of an economically viable well...

To fulfil the increase in global demand of clean energy, the dimensions of offshore wind turbines are expected to increase with greater capacities and move further offshore in deep waters. For these conditions, the diameter of the monopile will have to increase beyond current manufacturing capacities. The slip joint connection can provide a...

Persistent surveillance is an urgent proficiency. For security, surveillance cameras are a strong asset as they support the automatic tracking of people and are directly interpretable by a human operator. Radar on the other hand can be used under a broad range of circumstances: radar can penetrate mediums such as clouds, fogs, mist and snow, and...
