    Herbestemming religieus erfgoed

    No full text
    Het kasteel in Gemert is in 2010 vrijkomen te staan. Dit gebouw heeft naast monumentale waarden, ook gevoelswaarde voor de mensen in de omgeving. Nu dreigt sloop omdat de oorspronkelijke functie niet meer van toepassing is. Herbestemming kan nu nieuwe perspectieven bieden. Binnen de studio Gemert heb ik gezocht naar een opzet voor een nieuwe functie die de herbestemming van het Kasteel ter hand neemt.Kasteel GemertRMITArchitectur

    Heading in the right direction? Using head moves to traverse phylogenetic network space

    No full text
    Head moves are a type of rearrangement moves for phylogenetic net-works. They have primarily been studied as part of other types of moves, such as rSPR moves. Here, we study head moves as a type of moves on themselves. We show that the tiers (k > 0) of phylogenetic network space are connected by local head moves. Then, we show tail moves and head moves are closely related: sequences of tail moves can be converted into sequences of head moves and vice versa, changing the length by at most a constant factor. Because the tiers of network space are connected by rSPR moves, this gives a second proof of the connectivity of these tiers. Furthermore, we show that these tiers have small diameter by reproving the connectivity a third time. As the head move neighbourhood is small in general, this makes head moves a good candidate for local search heuristics. Finally, we prove that finding the shortest sequence of head moves between two networks is NP-hard.Optimizatio

    An Evaluation Framework for Linked Open Statistical Data in Government

    No full text
    Demographic, economic, social and other datasets are often used in policy-making processes. These types of statistical data are opened more and more by governments, which enables the use of these datasets by the public. However, statistical data needs often to combine different datasets. Data cubes can be used to combine datasets and are a multi-dimensional array of values typically used to describe time series of geographical areas. While Linked Open Statistical Data (LOSD) cube software is still in an initial stage of maturity, there is a need for evaluation the software platforms used to process this open data. Yet there is a lack of evaluation methods. The objective of this ongoing research paper is to identify functional requirements for open data cubes infrastructures. Eight main processes are identified and a list of 23 functional requirements are used to evaluate the OpenCube platform. The evaluation results of a LOSD platform show that many functions are not automated and need to be manually executed. We recommend the further integration of the building blocks in the platform to reduce the barriers for the use of datasets by the public.Information and Communication Technolog

    A Systematic Literature Study to Unravel Transparency Enabled by Open Government Data: The Window Theory

    No full text
    The opening of data has been credited for improving transparency and for providing a window on government functioning. Although this relationship is intuitively apparent, it is in fact complex and the mere opening of data might not actually yield transparency. In this paper, a comprehensive model of determinants that enable or impede transparency enabled by open government data and the expected effects have been derived by surveying public administration and information systems literature. Public administration literature tends to be focused on factors such as participation and trust, whereas information systems literature focuses on factors such as user interface, user experience, and data quality. Digital government literature attempts to bridge these elements. The Window Theory is introduced, in order to unify existing models by integrating a broad range of factors within a single model. The Window Theory can be used to develop context-dependent models that are both comprehensive and parsimonious.Information and Communication Technolog

    The elements of the Peer-to-peer (P2P) lending system: A Systematic Literature Review

    No full text
    Peer-to-peer (P2P) lending systems have gained governments' attention to create an inclusive society, but establishing such systems remain challenging. Specifically, the elements making up such a system are not known. This research aims to understand the main elements of P2P lending systems and their interconnections. For this, we conducted a Systematic Literature Review to investigate the elements that build the complex arrangement of the P2P lending system. Our review identified five categories of elements that build an integral part of the P2P lending system: Data and Processing, Business, Organizational, Policy and Governance, and Culture. Although technical aspects have gained much attention, social aspects need to be considered carefully. We conclude that P2P lending systems are context-dependent. Moreover, the interaction and the combination of each element influence the whole design of the system. These elements can assist the government in designing a socially accepted P2P lending system that contributes to an inclusive society.Information and Communication TechnologyEngineering, Systems and Service

    Comparing the topology of phylogenetic network generators

    No full text
    Phylogenetic networks represent evolutionary history of species and can record natural reticulate evolutionary processes such as horizontal gene transfer and gene recombination. This makes phylogenetic networks a more comprehensive representation of evolutionary history compared to phylogenetic trees. Stochastic processes for generating random trees or networks are important tools in evolutionary analysis, especially in phylogeny reconstruction where they can be utilized for validation or serve as priors for Bayesian methods. However, as more network generators are developed, there is a lack of discussion or comparison for different generators. To bridge this gap, we compare a set of phylogenetic network generators by profiling topological summary statistics of the generated networks over the number of reticulations and comparing the topological profiles.OptimizationDelft Institute of Applied Mathematic

    Public Values of Trustworthy Peer-To-peer (P2P) Lending System

    No full text
    Governments want to improve the economy by extending the market of financial credit. Recently, Peer-To-peer (P2P) lending credit scoring systems have gained more attention for advancing society; however, the role of governments in ensuring fair access to such a system is not known. This work aims to understand better the public values for trustworthy P2P lending systems. Public values should provide the basis to which a P2P lending system should adhere. Credit scoring in P2P lending is not merely about the technology in creating a profitable system for all participants. Several public values are of relevance. Understanding credit scoring in P2P lending is crucial to ensure inclusiveness, trustworthiness, fairness, equal treatment, and accountability.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Information and Communication TechnologyEngineering, Systems and Service

    Rearrangement operations on unrooted phylogenetic networks

    Rearrangement operations transform a phylogenetic tree into another one and hence induce a metric on the space of phylogenetic trees. Popular operations for unrooted phylogenetic trees are NNI (nearest neighbour interchange), SPR (subtree prune and regraft), and TBR (tree bisection and reconnection). Recently, these operations have been extended to unrooted phylogenetic networks-generalisations of phylogenetic trees that can model reticulated evolutionary relationships-where they are called NNI, PR, and TBR moves. Here, we study global and local properties of spaces of phylogenetic networks under these three operations. In particular, we prove connectedness and asymptotic bounds on the diameters of spaces of different classes of phylogenetic networks, including tree-based and level-k networks. We also examine the behaviour of shortest TBR-sequence between two phylogenetic networks in a class, and whether the TBR-distance changes if intermediate networks from other classes are allowed: for example, the space of phylogenetic trees is an isometric subgraph of the space of phylogenetic networks under TBR. Lastly, we show that computing the TBR-distance and the PR-distance of two phylogenetic networks is NP-hard.Optimizatio
