    (2015-01-01) Modeling Distributed Cybernetic Management for Resource Based Economies
    Haber, Janosch
    At the end of 1971, a group of early AI researchers around British economist Stafford Beer started working on a cybernetic approach to au- tomatize the administration of the entire Chilean economy. Although showing first successes, this project called CyberSyn was shut again only two years later after a military putsch, leaving the approach never to be concluded. In this research we aim to investigate whether the simple cybernetic approach proposed by Stafford and his colleagues would have be....................
    (2015-01-01) Sampling from Probabilistic Context-Free Grammars
    Bondt, Iason Sebastiaan de
    In this present study there are two sampling methods, applicable to PCFGs, implemented and compared with respect to each other, i.e. ancestral sampling (a form of Monte-Carlo sampling), and slice sampling (a form of Markov chain Monte-Carlo) sampling. Ancestral sampling requires the exact representation of the target probability density function, which can be computed with a chart-based parsing algorithm (e.g. CKY). However, due to the cubic complexity of such algorithms, these approaches become....................
    (2015-01-01) Drivers for the Evolution of Moral. Behaviour in Multi-Agent Societies
    Rijnbout, Jeroen
    This paper investigates the effects of various drivers on the evolution of moral behaviour to determine whether the theory of evolutionary ethics can be considered a valid explanation for the existence of moral behaviour. A canonical genetic algorithm is used to simulate evolution in a multi-agent system. Several drivers are studied to determine under what conditions societies can evolve moral behaviour. The models show that when co-operation is necessary to fully exploit the environment's resou....................
    (2015-01-01) Need help telling your life story? A critical study of capitalist ideology and narrative in self-help literature
    Dorrestijn, Margriet
    This thesis eleborates on Murat Aydemir’s notion of Character aesthetics, to explain how identity is formulated through aesthetic mediation structured by narrative. It examines the the cultural constructedness of identity and how abstract narrative structures are motivated by particular power-mechanisms and ideologies based on theories of Judith Butler and Foucault. Combined with Zygmunt Bauman's metaphorical concept of liquidity, it exposes how present-day capitalism can be seen as a driving ....................
    (2015-01-01) Archaeology and the Crowd. An Exploration of Socially Responsible Archaeology
    Ward, Andrea
    What this thesis endeavours to evaluate is the current state of the archaeology sector with what we know about the new developments and current state of crowdfunding and crowdsourcing in archaeological practice. How does it enhance research, heritage and public understanding of archaeology? While a variety of crowdfunding and crowdsourcing examples are highlighted within this thesis, the practical aspects of this research are tied in with two European case studies, the Netherlands Drentsche Aa r....................
    (2015-01-01) Taking up the RoCKIn@Work Object Recognition Challenge With The Bag of Keypoints Approach
    Shahbazian, Areg
    This research project addresses the problem of object-classification by a robot in an industrial context. Solving this problem brings industrial robots one step closer to being able to operate autonomously and eventually to reproduce themselves. The approach described in this thesis enables a systemto distinguish classes of objects using RGB data only, which can be a difficult task when the classes are similar. Other approaches have been to compare generic features of objects to classify them, ....................
    (2015-01-01) Automatic Recommender System over CMS stored content
    Egmond, Erik van
    Visitors are browsing sites on the World Wide Web looking for con- tent that can help them achieve their task; finding particular information, pages about their interest or products to buy. Webmasters want the visitor to find that content as quick and easy as possible, which can be achieved by recommending content. When this is done manually, the webmasters need to spend a lot of time on the recommendations. This thesis explores several options on the automation of the process by examining cont....................
    (2015-01-01) UTILIZATION OF LEARNING ANALYTICS TO OBTAIN PEDAGOGICALLY MEANINGFUL INFORMATION FROM DATA AND PRESENTING THE INFORMATION TO STUDENTS
    Huizen, Gerben van der
    Finding ways to extract pedagogically meaningful information from student data is a common issue in the field of learning analytics and educational data mining. One of the ways we can use this information is by presenting the data in such a way that students can use it to improve their learning strategies. In this paper different methods for extracting information from student data and methods for presenting this information to students are discussed. A model for predicting student performance ....................
    (2015-01-01) Your Worst Nightmare: An investigation into arousal-raising environmental sound features
    Kooij, David M. van der
    This thesis addresses the question of what properties of the mechani- cal representation of sounds are associated with high arousal emotions in humans. Furthermore, I hypothesise that these mechanical proper- ties are sufficient to find a particular high arousal sound, a nightmare sound, for each user individually. This study focuses on environmental sounds and does therefore not consider speech and music. Following Russell's model of affect, this thesis applies a scale of arousal as the p....................
    (2015-01-01) Development of a recommender system for Dutch case law, with the use of a topic model.
    Berg, Erwin van den
    Dutch case law is publicly available on rechtspraak.nl, there is however no publicly available recommender system for Dutch case law. The purpose of this project is to give useful suggestions within Dutch case law. These suggestions are generated by comparing the (pre-processed) texts of the case laws using a topic model. The topic model represents the case laws as mixtures of topics, after which the most similar case laws are found by calculating the similarity between the topic mixtures. The ....................
    (2015-01-01) Supporting OCR Impact Estimation on the Retrieval of the First Mention of A Concept in Historic Newspaper Archives
    Li, Xiaoli
    Digitized historical newspaper archives play an increasingly important role in humanities studies. However, Optical Character Recognition (OCR) errors significantly influence the dependability of search results. Being aware of such issues is essential when conducting specific humanities research tasks. In this paper, we describe the early phase of design and evaluation of a user interface that supports estimation of the impact of OCR errors on keyword retrieval, finding the first mention....................
    (2015-01-01) Forging the Welsh Nation: How has Intranational Distinction Hindered the Separatist Design?
    Hudson, Craig
    The 2014 Scottish Independence Referendum alerted people worldwide to the possible breakup of the United Kingdom (UK). Should Scotland vote ‘Yes’, would Wales similarly choose to follow it in seceding from the union? The question became a definitive feature of media attention up to and in the aftermath of the September referendum, where though Scotland ultimately rejected independence, a still sizeable part of its population had voted to go their separate way. By contrast, Welsh support f....................

    Lawrie, Robin
    The overwhelming majority of studies of genocidal violence have, when examining the role played by the perpetrators of such violence, focussed solely on men. The role of women in genocide, this study will focus on the Rwandan genocide of 1994, has predominantly been represented as that of the victim. This representation is consistent with traditional gendered perspectives found in most scholarly work on genocide, many established schools of thought relating to gender studies and feminism, and wi....................
    (2015-01-01) On a decade of reluctant reform in US intelligence
    Jacobs, Dirk
    Following the end of the Cold War intellectuals and opinion makers in the US, for instance Fukuyama and Huntington, recognized a moment in history when policy makers had the opportunity to radically change the intelligence industry to create a peace dividend. The National Reconnaissance Office, the intelligence organization managing and developing satellite reconnaissance, tried to adapt to the demands of the new era. However, similarly to the CIA, the expectations of outsiders did not match eve....................
    (2015-01-01) Legitimating Quality: A Study of Multiculturalism, Exclusion, and the Integration of Quality TV within the Dutch Mediascape
    Bos, Josephina
    For many years now, quality television has been a phenomenon that has gained critical attention from both television industry and academia. It is still, up to this day, a debated concept that lacks a clear definition and is often being condemned for its evaluative nature. In this thesis I therefore present my definition of what quality TV as a concept entails, using the Dutch mediascape as a case study to illustrate how quality television, although a debated and controversial term, does in fact ....................
    (2015-01-01) CONTRASTUEEL DUALISME IN DE ODEN VAN SALOMO EN DE JOHANNEÏSCHE GESCHRIFTEN
    Appeldoorn, Gijsbert van
    In deze scriptie worden drie geschriften vergeleken daterend rond het jaar 100 van onze jaartelling, namelijk de Oden van Salomo, het Johannes' evangelie en 1 Johannes. Ze worden vergeleken op basis van het gebruik van contrasten. In alle drie de werken komen de contrasten licht versus duisternis, liefde versus haat en waarheid versus leugen terug. Het gebruik van deze contrasten wordt onderverdeeld in drie vormen van gebruik, namelijk om de antropologie, de christologie en de theologie te besch....................
    (2015-01-01) What Deep Neural Networks see, but we don’t
    Hoppenbrouwer, Joost P.J.
    While recent studies demonstrate how deep neural networks can be fooled on the task of visual classification and since deep neural networks are widely used for this task the importance of understanding this phenomena becomes greater every day. This thesis shows how a pattern arises when comparing the activation patterns of a so-called fooling image within a deep neural network to the activation patterns of correctly classified images gathered from the ImageNet data-set. By using several metrics....................
    (2015-01-01) Saving energy in buildings using an Artificial Neural Network for outlier detection
    Lodewegen, Jonas
    This project, based on previous work by De Nadai (2013), applies an artificial neural network for the prediction of gas consumption of buildings of the Hogeschool van Amsterdam. An outlier detection method based on Chebyshev’s theorem is used in order to detect anomalies in this consumption. Furthermore, a combined outlier detection is proposed to distinguish between causes of anomalies. Besides this, an attempt is made to create a generic predicting model that parametrises buildings based on ....................
