Ambiguities are an often encountered nuisance in signal processing and are the source of some of the fundamental trade-offs encountered in radar systems. The goal of this thesis is to extract unambiguous information about targets by combining a limited amount of measurements on a video integration level. A novel framework is proposed to reach...

"Brussels was never destroyed by the wars, but rather by its own people" these words of Victor Bourgouis show the destructive vision of social and cultural spaces in Brussels. The city's vision of urban development is based on top-down politics, fed by the desire to be modern. This affection leads to the non-identification and displacement of...

Instead of predicting just one emotion for one activity (e.g., video watching), fine-grained emotion recognition enables more temporally precise recognition. Previous works on fine-grained emotion recognition require segment-by-segment, fine-grained emotion labels to train the recognition algorithm. However, experiments to collect these...

Precise point positioning-real-time kinematic (PPP-RTK), otherwise known as integer ambiguity resolution-enabled precise pointing positioning, has attracted much attention in recent years and has become state-of-the-art in the global navigation satellite system (GNSS) high-precision positioning community. This work reviews several PPP-RTK...

To obtain single-receiver Global Navigation Satellite System (GNSS) parameter solutions, the PPP-RTK user-filter combines measurements with time-correlated corrections that are separately computed by the filter of an external provider. The consequence of exercising such double-filtering is that the Kalman filter’s standard assumption of...

Liquid storage tanks play a vital role in the modern chemical process industry (CPI). The strong ground motion caused by large-scale earthquakes may easily impose severe structural damage on liquid storage tanks, leading to a series of catastrophic cascaded events. The seismic damage estimation of liquid storage tanks is a challenging problem,...

To make the supply of transport services more attractive and sustainable, mobility suppliers and governmental actors expect much from mobility innovations. When developing and realizing these innovations, they experience considerable uncertainty about the future outcomes of implementing these innovations (1), and about other actors' intentions...

Carrier phase signals are considered among the key observations in global navigation satellite systems (GNSSs) and several other high-precision interferometric measurement systems. However, these ultra-precise measurements are not fully exploited when the integerness of their inherent ambiguities is discarded during the estimation process....

Ambiguity is gaining attention in self-tracking research as a means to go beyond the mere quantification of body signals. Recent research has suggested that ambiguity can be used even to enable social connection mediated by personal data. To explore this design space more widely, we organized two design workshops with a total of 67...

Micro mobility services aim to offer people new and more convenient modes of transport, usually across urban areas. In order to achieve this they make use of public space to implement their infrastructure on, for example by allowing people to freely park a vehicle almost anywhere in the city. One can imagine that this has a major impact on how...

Precise Point Positioning (PPP) is a Global Navigation Satellite Systems (GNSS) modelling and processing method that provides single-receiver users with high positioning accuracy anywhere on the globe, without the explicit dependence on reference receivers. The realization of PPP is based on undifferenced code and phase measurements, a priori...

In times when robustness and optimisation have become some of the guiding principles of design, it is clear that instant problem-solving solutions prove to be insufficient as long-term resilience strategies. In this context, ambiguity is seen as an alternative approach to answering the issues of adaptability and flexibility of delta conditions...

The project can be defined at the intersection of urban landscape, architecture and infrastructure as a resolution of not only social flows but also the systems and elements of the material flows, which once shaped London. It aims to formulate new social urban programs where the distinction between the site, the architectural edifice or the...

The corrections needed to realize integer ambiguity resolution-enabled precise point positioning (PPP-RTK) at a single-receiver user are often treated as if they are deterministic quantities. The present contribution aims to study and analyze the effect the neglected uncertainty of these corrections, which are subject to time delay, has on...

High angular resolution is in high demand in automotive radar. To achieve a high azimuth resolution a large aperture antenna array is required. Although MIMO technique can be used to form larger virtual apertures, a large number of transmitter-receiver channels are needed, which is still technologically challenging and costly. To circumvent this...

Quantum Mechanics could have fundamental impact on design models and measurement. Quantum mechanics allows us to fill in the blanks of classical models of design, through its ability to explain ambiguous states of design. An ambiguous state is where design exists in between two binary states, as a superposition. Designers are most likely to...

Pose estimation in robotics is often achieved using images from known and purposefully applied markers or fiducials taken by a monocular camera. This low-cost system architecture can provide accurate and precise pose estimation measurements. However, to prevent the restriction of robotic movement and occlusions of features, the fiducial markers...

The sensing properties of the binary phase codes are investigated with their application to phase-coded (linearly) frequency modulated continuous waveform (PC-FMCW). It is shown that the ambiguity function of FMCW signal modulated with a binary phase code corresponds to sheared ambiguity function of the code itself. The range profiles of PC...

This project develops and tests algorithms for joint signal processing of data from two radars located on the rooftop of EWI (PARSAX and MESEWI). The particular tasks consist of automatic alignment of radar data in space (2D map) and time by observing moving targets of opportunity in the high-resolution mode. After the data alignment procedure,...

Context-free grammars (CFGs) provide a well-known formalism for the specification of programming languages. They describe the structure of a program in terms of parse trees. One major issue of CFGs is ambiguity, where one sentence can sometimes have multiple different parse trees. Some formalisms like SDF3 or YACC allow annotating a grammar with...
