Travelling through airports can be quite a stressful experience for passengers. Airlines, such as KLM, want to make the journey of their passengers through airports as comfortable as possible. This thesis proposes an indoor localization system for airlines called AirLoc. The research question was: "Which airport specific indoor localization...

Spacecraft attitude refers to the orientation of the spacecraft body axes with respect to the inertial reference frame. Attitude determination and control is the estimation of the current orientation of a satellite and controlling or changing it on demand to reach a desired orientation. The SPS-2 Attitude Control System consists of four modes:...

With the advent of smart thermostats like Toon®, detailed information about operation and usage of central heating boilers has become easily available. However, this information is not used in a systematic way by most companies including Eneco, and the wealth of information within is not available to the users. This has a few drawbacks. For...

For decades, researchers try to model the subsoil as accurate as possible in order to make cost-efficient and safe geotechnical decisions. A troublesome aspect in modelling of the soil is to determine the heterogeneity within the soil, as this is usually associated with a great deal of uncertainty. Delft University of Technology used a recursive...

This thesis aims to analyse the conservatism in the current Dutch recommendations on the external friction angle 𝛿 of diaphragm walls: 𝛿 = 𝑚𝑖𝑛[𝜙, 20°] (for curved slip surfaces) (CUR/COB, 2010), by means of an experimental investigation. Based on literature, two sources of conservatism are identified: 1) filter cake contamination by excavated...

The tremendous growth of the Internet brings with it a massive amount of data that users are exposed to on a daily basis. Consequently, information filtering techniques like recommender systems have become increasingly important to sift through the data and find what is relevant to a particular user. A recent approach for recommender systems,...

Mobile robots need to interact with their environment to perform their tasks. To be successful they often need to know what their surrounding looks like, and where they are located in that surrounding. The act of simultaneously estimating both the state of the robot and the state of the environment is called Simultaneous Localization And Mapping...

In the elderly population, falls are one of the major causes of injuries. Fall detection algorithms for wearable devices in the literature were found to focus on differentiating Activities of Daily Living (ADL) from falls, rather than on early fall detection and prevention before impact. This thesis work was aimed at providing accurate estimates...

When talking about personalization online, Google CEO Eric Schmidt recently said "it will be very hard for people to watch or consume something that has not in some sense been tailored for them." This level of personalized filtering of content has worried academics and activists. Many argue that users will be trapped in a so-called "Filter...

Bilateral cochlear implants (CIs) can restore hearing in deaf children, by electrically stimulating the auditory pathways. The effects of long-term deafness have been extensively studied and it is well known that deafness leads to cross-modal reorganization of the brain. However, the short term effects of CI use on the developing auditory...

Convex guidance is a developing guidance algorithm that seeks to unify the trajectory optimisation for pin-point landings. The unification would mean the elimination of the need of different optimisation techniques for different stages of the landing. Using convex optimisation, convex guidance is guaranteed to find the global-optimum of the design...

Four Wheel Drive (4WD) vehicles are almost as old as the automobile itself, however for more than half a century the main use case of a 4WD system was to improve traction on off-road terrains. The advancement in technology over the recent decades resulted in more advanced and light weight solutions shifting the focus more towards sports cars and...

Worldwide 748 million people lacked access to improved sources of drinking water in 2014, of this group almost a quarter relies on untreated surface water (WHO & Unicef, 2014). According to the WHO, simple, socially accepted and low-cost household water treatment systems (HWTS), such as the Ceramic Pot Filter (CPF), can provide a solution for...

Safety and reliability of a dynamical system is a concern that have always pursued designers in both academia and industry. Monitoring the health status of a system is even more relevant for safety critical applications, such as chemical and nuclear plants, medicine, transportation, and security systems. The occurrence of abnormal events on...

This thesis discusses the applicability of assimilation of artificial SMAP data into a quasi steady state hydrological model to improve soil moisture estimates. The model used for this research was SIMGRO and since no real SMAP data were available at the time of the research, artificial SMAP data were used. The ensemble Kalman filter was used to...

In Nicaragua, active research for arsenic started in 1996, after the first case of arsenic poisoning was reported in a rural community. Arsenic concentrations present in drinking water cause chronic poisoning, which depending on the exposure, lead to several life-threatening long term effects. It is however unknown to what extent this...

Aeration and rapid sand filtration are common practice for the treatment of iron, manganese and ammonium containing ground water for more than a century. Nevertheless, this process has not become obsolete. On the contrary, this thesis assumes that enhanced rapid sand filters remain standard treatment technology in the 21st-century. Iron can be...
