Thermal-Aware Synthesis of 5G Base Station Antenna Arrays: An Overview and a Sparsity-Based ApproachAslan, Y. (author), Puskely, J. (author), Janssen, J. H. J. (author), Geurts, Marcel (author), Roederer, A.G. (author), Yarovoy, Alexander (author)Heat removal capabilities and radiation performances of several sparse antenna array topologies are studied for cooling enhancement in 5G millimeter-wave base station antennas. Both electromagnetic and thermal aspects are jointly considered for the first time in array layout optimization and a novel connection between layout sparsity and thermal...journal article 2018

Cabrall, C.D.D. (author), Janssen, Nico (author), de Winter, J.C.F. (author)Background<br/>Automated driving is often proposed as a solution to human errors. However, fully automated driving has not yet reached the point where it can be implemented in real traffic. This study focused on adaptively allocating steering control either to the driver or to an automated pilot based on momentary driver distraction measured...journal article 2018

van Ham, M. (author), Tammaru, T. (author), Janssen, H.J. (author)This chapter develops a multi-level conceptual model of segregation, by using three conceptual levels – individuals and households, generations, and urban regions. Different socio-economic groups sort into different types of neighbourhoods and other domains, leading to patterns of segregation at the urban regional level. At the same time...book chapter 2018

Kuiper, E.J. (author), Janssen, M.F.W.H.A. (author)Tax Administrations have a huge amount of tax-related data that can be re-used for the benefit of the taxpayers, similarly to the way private banks and wealth managers use their clients’ financial information. However, usage of tax data is not trivial, as Tax Administrations have to adhere to legislation that does not allow them to compete with...journal article 2018

Matheus, R. (author), Janssen, M.F.W.H.A. (author), Maheshwari, D. (author)Dashboards visualize a consolidated set data for a certain purpose which enables users to see what is happening and to initiate actions. Dashboards can be used by governments to support their decision-making and policy processes or to communicate and interact with the public. The objective of this paper is to understand and to support the...journal article 2018

Charalabidis, Yannis (author), Alexopoulos, Charalampos (author), Janssen, M.F.W.H.A. (author), Lampoltshammer, Thomas (author), Ferro, Enrico (author)Data represents a key asset in virtually any aspect of society and economy. Open Data in particular represents a source of immense value, as social capital (Lampoltshammer & Scholz, 2017) as well as an asset for business cases. Governments and their public administrations are generating and collecting during their service a plethora of...book chapter 2018

Shishkov, Boris (author), Janssen, M.F.W.H.A. (author)Networked physical devices, vehicles, home appliances, and other items embedded with electronics, software, sensors, actuators, and connectivity, allow for run-time acquisition of user data. This in turn can enable information systems which capture the “current” user state and act accordingly. The use of this data would result in context...conference paper 2018

Garvanova, Magdalena (author), Shishkov, Boris (author), Janssen, M.F.W.H.A. (author)Public values are desires of the general public, that are about properties considered societally valuable, such as respecting the privacy of citizens or prohibiting polluting activities. “Translating” public values into functional solutions is thus an actual challenge. Even though Value-Sensitive Design (VSD) is about weaving public values in...conference paper 2018

A fuzzy multi-criteria decision making approach for analyzing the risks and benefits of opening dataLuthfi, A. (author), Rehena, Z. (author), Janssen, M.F.W.H.A. (author), Crompvoets, Joep (author)Governments are releasing their data to the public to accomplish benefits like the creation of transparency, accountability, citizen engagement and to enable business innovation. At the same time, decision-makers are reluctant to open their data due to some potential risks like misuse, sensitivity, ownership, and inaccuracy of the data. The...conference paper 2018

Hulstijn, Joris (author), Darusalam, D. (author), Janssen, M.F.W.H.A. (author)There has been a lot of research on the use of open data in the fight against corruption. Although there are some promising examples, it appears that a systematic approach is lacking. What are the design principles for an architecture to open up data and thereby reduce corruption? In this paper we use theory about fraud, and about public...journal article 2018

Rehena, Z. (author), Mondal, Md Ashifuddin (author), Janssen, M.F.W.H.A. (author)Smart cities are struggling with using public space efficiently and decreasing pollution at the same time. For this governments have embraced smart parking initiatives, which should result in a high utilization of public space and minimization of the driving, in this way reducing the emissions of cars. Yet, simply opening data about the...conference paper 2018

(author)Business-to-government (B2G) information sharing can benefit government organisations, as well as businesses. Yet, businesses are often reluctant to share, as data sharing might not just provide benefits but also entails risks. Therefore, a system supporting B2G information sharing should provide the appropriate level of openness, such that the...conference paper 2018
