Katsimerou, C. (author)Affect-adaptive systems have the potential to assist users that experience systematically negative moods. This thesis aims at building a platform for predicting automatically a person’s mood from his/her visual expressions. The key word is mood, namely a relatively long-term, stable and diffused affective state, as opposed to the short-term,...doctoral thesis 2016

Liem, C.C.S. (author)Music is a multifaceted phenomenon: beyond addressing our auditory channel, the consumption of music triggers further senses. Also in creating and communicating music, multiple modalities are at play. Next to this, it allows for various ways of interpretation: the same musical piece can be performed in different valid ways, and audiences can in...doctoral thesis 2015

Kofler, C. (author)Over the recent years, user expectations of the ability of video search engines have significantly risen. Users expect video search engines to be useful as an instrument that facilitates communication, education, entertainment and problem solving and, in relation to this, to satisfy diverse information needs. A user's information need is the...doctoral thesis 2015

Zhang, T. (author)A common way to present 3D materials to human observers nowadays is by stereoscopic displaying on 3D TVs or head-mounted displays such as the Oculus Rift. However, not everyone can see three-dimensional solid shape from stereoscopic viewing and the three-dimensional images remain two-dimensional pictures to them rather than solid shapes....doctoral thesis 2015

Babaei, S. (author)Cancer is a complex disease that results from alterations in genes that control the growth and division mechanisms of the cell. Identifying cancer-associated genes and pathways through which these genes influence cellular function is the key challenge in cancer re- search. This thesis proposes novel computational approaches that integrate data...doctoral thesis 2015

Cohen, I. (author)Professionals working in different domains often experience stressful conditions evoked by disasters or crisis scenarios. Regardless of these conditions, they have to perform at high standards in order to preserve safety for themselves, avoid any casualties, and to resolve the overall situation. Stress, however, negatively affects cognitive...doctoral thesis 2015

Plasencia Calaña, Y. (author)Automatic pattern classification for a given problem domain aims at assigning a class or category membership to a new unseen object from the same domain. This is performed in three main stages: data preprocessing, representation and classification. The data preprocessing highly depends on the data type (e.g. images, signals) which makes its...doctoral thesis 2015

Kroes, T. (author)This thesis revolves around the development of medical visualization tools for the planning of CSG-based surgery. To this end, we performed an extensive computerassisted surgery (CAS) literature study, developed a novel optimization technique for customizable surgical guides (CSG), and introduce three visualization techniques to make the...doctoral thesis 2015

Alers, H. (author)While the world we live in becomes more saturated with ubiquitous digital displays, and as the threshold for creating digital media continues to drop, image quality is an issue that concerns an increasingly large segment of the population. Higher resolutions, increased dynamic range, and faster frame rates put increasing demands on resources...doctoral thesis 2015

Zeng, Y. (author)In digital speech communication applications like hands-free mobile telephony, hearing aids and human-to-computer communication systems, the recorded speech signals are typically corrupted by background noise. As a result, their quality and intelligibility can get severely degraded. Traditional noise reduction approaches process signals recorded...doctoral thesis 2015

Cheplygina, V. (author)Multiple instance learning (MIL) is an extension of supervised learning where the objects are represented by sets (bags) of feature vectors (instances) rather than individual feature vectors. For example, an image can be represented by a bag of instances, where each instance is a patch in that image. Only bag labels are given, however, the...doctoral thesis 2015

Yang, S. (author)In most types of networks (e.g., optical or transportation networks), finding one or more best paths from a source to a destination, is one of the biggest concerns of network users and providers. This process is known as routing. The routing problems differ accordingly depending on different application scenarios with their respective routing...doctoral thesis 2015

Wei, C. (author)Multi-robot teams have potential advantages over a single robot. Robots in a team can serve different functionalities, so a team of robots can be more efficient, robust and reliable than a single robot. In this dissertation, we are in particular interested in human level intelligent multi-robot teams. Social deliberation should be taken into...doctoral thesis 2015

De Jong, J. (author)DNA is packaged together with proteins, such as histones, in the nucleus of a cell to form a fiber called chromatin. The nature of this packaging, the "chromatin structure", is essential for proper cell functioning. This is illustrated by the fact that perturbating chromatin can be associated with many diseases. Hence, artificial perturbation of...doctoral thesis 2015

Sontrop, H.M.J. (author)Microarrays offer biologists an exciting tool that allows the simultaneous assessment of gene expression levels for thousands of genes at once. At the time of their inception, microarrays were hailed as the new dawn in cancer biology and oncology practice with the hope that within a decade diseases like breast cancer would be solved. Various...doctoral thesis 2015

Van de Bovenkamp, R. (author)Local interactions on a graph will lead to global dynamic behaviour. In this thesis we focus on two types of dynamic processes on graphs: the Susceptible-Infected-Susceptilbe (SIS) virus spreading model, and gossip style epidemic algorithms. The largest part of this thesis is devoted to the SIS model. We first introduce the SIS model in chapter...doctoral thesis 2015

Kok, P. (author)Molecular imaging techniques have been developing rapidly over the past decades, especially in preclinical research. As molecular imaging is applied more frequently, more and more data is generated from longitudinal studies, often in various modalities. The increasing amount of data poses a number of visualization challenges for researchers, who...doctoral thesis 2014
