Janssen, R. (author), Liu, Pengyu (author)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...journal article 2021

van der Voort, H.G. (author), van Bulderen, Sabine (author), Cunningham, Scott (author), Janssen, M.F.W.H.A. (author)The road from data generation to data use is commonly approached as a data-driven, functional process in which domain expertise is integrated as an afterthought. In this contribution we complement this functional view with an institutional view, that takes data analysis and domain professionalism as complementary (yet fallible) knowledge...journal article 2021

Dun, H. (author), Tiberius, C.C.J.M. (author), Diouf, C.E.V. (author), Janssen, G.J.M. (author)This paper presents a methodology to design a sparse multiband ranging signal with a large virtual bandwidth, from which time delay and carrier phase are estimated by a low complexity multivariate maximum likelihood (ML) method. In the estimation model for a multipath channel, not all reflected paths are considered, and time delay and carrier...journal article 2021

Weerakkody, Vishanth (author), Janssen, M.F.W.H.A. (author), El-Haddadeh, Ramzi (author)The realisation of citizen-centric services in the public sector requires breaking traditional silos and transforming existing institutional structures and processes. Recent transformation efforts undertaken in government institutions have embraced business process re-engineering (BPR) concepts championed by the private sector over decades...journal article 2021

Diouf, C.E.V. (author), Janssen, G.J.M. (author), Dun, H. (author), Kazaz, T. (author), Tiberius, C.C.J.M. (author)For validation and demonstration of high accuracy ranging and positioning algorithms and systems, a wideband radio signal generation and acquisition testbed, tightly synchronized in time and frequency, is needed. The development of such a testbed requires solutions to several challenges. Tight time and frequency synchronization, derived from...journal article 2021

Janssen, R. (author)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...journal article 2021

Zhu, Yonghan (author), Janssen, M.F.W.H.A. (author), Wang, Rui (author), Liu, Yang (author)The global spread of COVID-19 has caused a huge number of confirmed cases and deaths, which in return leads to a plethora of mental disorders across the world. In order to address citizens’ psychological problems, government agencies in many countries have employed AI-based chatbots to provide mental health services. However, there is a...journal article 2021

Kuğuoğlu, B.K. (author), van der Voort, H.G. (author), Janssen, M.F.W.H.A. (author)Despite the promise of AI and IoT, the efforts of many organizations at scaling smart city initiatives fall short. Organizations often start by exploring the potential with a proof-of-concept and a pilot project, with the process later grinding to a halt for various reasons. Pilot purgatory, in which organizations invest in small-scale...journal article 2021

Mondal, Md Ashifuddin (author), Rehena, Zeenat (author), Janssen, M.F.W.H.A. (author)Smart parking is becoming more and more an integral part of smart city initiatives. Utilizing and managing parking areas is a challenging task as space is often limited, finding empty spaces are hard and citizens want to park their vehicles close to their preferred places. This becomes worse in important/posh areas of major metropolitan cities...journal article 2021

Janssen, H.J. (author), Bruinsma, Gerben J.N. (author), Weerman, Frank M. (author)The aim of the current study is to provide an empirical test of containment theory of Walter Reckless (1899–1988). The theory proposes that outer and inner containment hold adolescents back from delinquency even when external factors pull and push them toward it. This early control theory was ahead of its time, but never received the...journal article 2021

Janssen, C. (author), Daamen, T.A. (author), Verdaas, J.C. (author)In Europe, growing concerns about social segregation and social stability have pushed calls to make cities ‘inclusive, safe, resilient and sustainable’ higher on policy agendas. However, how to approach such generic policy objectives and operationalise them for planning practices is still largely unclear. This article makes a conceptual...journal article 2021

(author), Caviglia, A.

A notable example is the interface between polar and nonpolar materials, where valence discontinuities lead to otherwise inaccessible charge and spin states. This approach...journal article 2021
