Twitter contains massive amounts of user generated content that also contains a lot of valuable information for various interested parties. Twitcident has been developed to process and filter this information in real-time for interested parties by monitoring a set of predefined topics, exploiting humans as sensors. An analysis of the relevant...

The Simultaneous Localization and Mapping (SLAM) problem for mobile robots aims at consistently building a map of an unknown environment while simultaneously determining its position within this map. From a control-theoretic viewpoint, it is somehow analogous to simultaneously estimating the states and output map of the system. In the robotics...

Knowledge of the state of balance of the moving human is essential for the design of fall detection algorithms and wearable robotic controllers for balance assistance. Still, there is no known general method to make an online estimation of the state of balance of the walking human, with the limited and local sensor measurements that are usually...

Traffic state estimations and predictions are essential parts for dynamic traffic management applications. This thesis consists of two parts: firstly the requirements for application of a traffic prediction tool in a road traffic management center are analysed, and a design is made for a tool to function in non-recurrent conditions and cope with...

Traffic state estimation is an important element in traffic management systems. In this research a freeway traffic state estimation methodology is proposed which allows to incorporate the information and uncertainties of heterogeneous data-types, namely loop-detector data and floating car data. The loop-detector data provides estimation of speed...

The fusion of measurements from distributed sensors for dynamic positioning (DP) system based on state estimation algorithms is studied in this thesis in order to increase the accuracy and redundancy of the reference system in DP and a state observer is also designed to estimate of the low frequency vessel motion for the input of DP controller....

A filter can be applied to protect a bed against scour. Normally, these filters are geometrically closed, to prevent winnowing of the base material through the filter. However, geometrically closed filters are expensive and difficult to realize in the field. Geometrically open filters can serve as an alternative. Within an open filter, the pores...

In synchronization of high-precision stages systems, particularly the one between the wafer stage system and the reticle stage system of a wafer scanner, a novel feedforward control structure capable of achieving zero-settling errors is presented. The synchronization is achieved by including finite impulse response (FIR) filters both in the...

With the ever increasing demand of cars, safety is of prime concern to automobile manufactures across the world. Companies strive for the vision of "Zero accidents" through high quality and innovative products that reduce the frequency of accidents as well as their consequences. The auto industry has been exerting a myriad of state-of-the-art...

Most recommender systems recommend items from a single domain. However, usually users’ preferences span across multiple domains. Cross-domain recommender systems can successfully recommend items in multiple domains when there is knowledge about the user’s preferences for items in at least one of the domains and when there is knowledge about...

Every spacecraft carries small rocket engines called thrusters for the purpose of orbit and position corrections in space. A precise operation of the thrusters saves fuel and a lower fuel consumption can extend the service life of the spacecraft. Precise thrust levels can be better obtained by pulsed firing than by continuous firing of the...

Electronic stability control (ESC) has been shown to reduce the accident rate in a number of situations. Therefore, it is important to keep improving ESC and other control systems. One way to do this is by improving the available information on the state of the vehicle and its environment. The tire-road friction coefficient µ is particularly...

In order to address the problem of indoor pedestrian tracking, this thesis reports a research on spatial models' ability to reduce tracking error of a WiFi positioning system. There are three main objectives in this research. First, it is to build a suitable spatial model for tracking. Second, it is to develop a tracking algorithm that can make...

Humanoid robots could perform a large variety of tasks, ranging from helping the elderly and entertainment to carrying out repairs in hazardous environments such as nuclear power plants. Therefore, they are an important topic of research. However, controlling the balance of two-legged robots still proves to be a challenge, especially during more...

The dynamics of systems can be analysed by combining the dynamics of its components. This method is generally know as dynamic substructuring. It allows for efficient computation of the dynamics of structures that would otherwise be to complex to determine. Most dynamic substructuring approaches use the frequency domain for the re-assembling of...

The use of sensor measurement data in mines today is usually limited to the downstream processing of mined material in a feed-forward loop. This thesis investigates the capability of Kalman Filtering techniques in updating resource models, based on sensor data, in a feed-back sense. The mining operation and updating process are simulated in...

The oil industry is at the backbone of global economy and, as natural resources are becoming scarce, there is a pressing need for efficient extraction strategies. This has led to the development of reservoir models and simulators, able to predict future field behaviour, when paired with accurate geological information. However, the data obtained...

The ecological state of the North Sea surface water can be indicated by ocean variables such as the Chlorophyll-a (Chlfa) concentration. Chlfa is the principal photosynthetic pigment and is common to all phytoplankton and can therefore be used as a measure of phytoplankton biomass. The GEM/BLOOM model developed at Deltares is a generic...
