Gong, Yiwei (author), Janssen, M.F.W.H.A. (author)Organizations have adopted Enterprise Architecture (EA) for managing their IT-landscape and ensuring coherence among projects and activities. There is much work about approaches, methods, and tools for EA based on the assumption that their use will create business value. However, the failure of many EA efforts results in the need to...conference paper 2020

Janssen, R. (author), Jones, M.E.L. (author), Murakami, Yukihiro (author)Phylogenetic networks are important for the study of evolution. The number of methods to find such networks is increasing, but most such methods can only reconstruct small networks. To find bigger networks, one can attempt to combine small networks. In this paper, we study the Network Hybridization problem, a problem of combining networks...conference paper 2020

Janssen, R. (author), Murakami, Yukihiro (author)Phylogenetic networks are used to represent evolutionary scenarios in biology and linguistics. To find the most probable scenario, it may be necessary to compare candidate networks, to distinguish different networks, and to see when one network is embedded in another. Here, we consider the Network Containment problem, which asks whether a...conference paper 2020

Tangi, Luca (author), Janssen, M.F.W.H.A. (author), Benedetti, Michele (author), Noci, Giuliano (author)The introduction of ICT is requiring public administrations to transform their organizations to take advantage of these technologies. Despite its significance, no studies so far collected quantitative evidence on (i) how and the extent to which this transformation is currently underway and (ii) which drivers and barriers are hindering and...conference paper 2020

Wouters, Stijn (author), Janssen, M.F.W.H.A. (author), Crompvoets, Joep (author)Governments aim to digitalize public services. Whereas initially they worked in isolation, nowadays they increasingly link different building blocks together to realize integrated public services. This evolution poses challenges concerning the governance of public services. The purpose of this paper is to identify governance challenges in...conference paper 2020

Kazaz, T. (author), Coutino, Mario (author), Janssen, G.J.M. (author), Leus, G.J.T. (author), van der Veen, A.J. (author)Synchronization and ranging in internet of things (IoT) networks are challenging due to the narrowband nature of signals used for communication between IoT nodes. Recently, several estimators for range estimation using phase difference of arrival (PDoA) measurements of narrowband signals have been proposed. However, these estimators are based...conference paper 2019

(author)Achieving high resolution time-of-arrival (TOA) estimation in multipath propagation scenarios from bandlimited observations of communication signals is challenging because the multipath channel impulse response (CIR) is not bandlimited. Modeling the CIR as a sparse sequence of Diracs, TOA estimation becomes a problem of parametric spectral...conference paper 2019
