Andreykiv, A. (author), Janssen, D. (author), Nelissen, R.G.H.H. (author), Vlastar, E.R. (author)Background Cement injection into osteolytic areas around the cement mantle is a technique for refixation of loose hip implants for patients who cannot undergo standard revision surgery. Preliminary clinical results show the improvement in walking distance, patients' independence and pain relief. Methods In this study, we use a detailed finite...journal article 2012

Janssen, R.M.J. (author), Endo, A. (author), Baselmans, J.J.A. (author), De Visser, P.J. (author), Barends, R. (author), Klapwijk, T.M. (author)The sensitivity of microwave kinetic inductance detectors (MKIDs) based on coplanar waveguides (CPWs) needs to be improved by at least an order of magnitude to satisfy the requirements for space-based terahertz astronomy. Our aim is to investigate if this can be achieved by reducing the width of the CPW to much below what has typically been made...journal article 2012

Janssen, M.F.W.H.A. (author), Klievink, B. (author)Purpose – In the process of transformation, governments have to deal with a host of stakeholders and complex organizational and technical issues. In this viewpoint paper, an argument is made in favour of using gaming and simulation as tools designed to aid the transformation and reengineering of government. Based on the argument, a research...journal article 2010

Sorokin, D.Y. (author), Van den Bosch, P.L.F. (author), Abbas, B. (author), Janssen, A.J.H. (author), Muyzer, G. (author)Thiopaq biotechnology for partial sulfide oxidation to elemental sulfur is an efficient way to remove H2S from biogases. However, its application for high-pressure natural gas desulfurization needs upgrading. Particularly, an increase in alkalinity of the scrubbing liquid is required. Therefore, the feasibility of sulfide oxidation into...journal article 2008

Penkin, D. (author), Janssen, G. (author), Yarovoy, A. (author)The power budget of a wireless link between two electrically small sensor nodes located close to an interface between two media is studied. The model includes both the propagation channel losses and input impedance of the radio frequency antennas. It is shown that a highly inductive half-space significantly enhances the received power due to the...journal article 2014

(author)We demonstrate photon noise limited performance in both phase and amplitude readout in microwave kinetic inductance detectors (MKIDs) consisting of NbTiN and Al, down to 100 fW of optical power. We simulate the far field beam pattern of the lens-antenna system used to couple radiation into the MKID and derive an aperture efficiency of 75%. This...journal article 2013

Penkin, D. (author), Janssen, G.J.M. (author), Yarovoy, A. (author)To effectively localise a source node in a dense wireless tiny-sensor network with an arbitrary 2D/3D node distribution, a novel approach suitable to describe the hop progress of source-to-sink path in such a system is proposed. In this approach, the network topology is described as a regular lattice and relates the statistical parameters of the...journal article 2014

Smit, P.B. (author), Janssen, T.T. (author)The interaction of ocean waves with variable currents and topography in coastal areas can result in inhomogeneous statistics because of coherent interferences, which affect wave-driven circulation and transport processes. Stochastic wave models, invariably based on some form of the radiative transfer equation (or action balance), do not account...journal article 2013

Janssen, M.F.W.H.A. (author), Chun, S.A. (author), Gil-Garcia, J.R. (author)Digital Government Infrastructures provide generic functionalities that are used by large numbers of users. Typically, they have no central authority, are governed by networks and contain both emerging and purposefully designed parts. Their use varies over time, and a large number of individuals use them for different purposes. The basic digital...journal article 2009

Janssen, M.F.W.H.A. (author), Klievink, B. (author)Purpose: Scant attention has been given to the role of enterprise architecture (EA) in relationship to risk management in information system development projects. Even less attention has been given to the inter-organizational setting. The aim of this paper is to better understand this relationship. Design/methodology/approach: The relationship...journal article 2012

Joha, A. (author), Janssen, M.F.W.H.A. (author)The sourcing of cloud services is a relatively new type of service delivery model in which an organization gets access to IT services via a cloud service provider that is delivering services over the web to many users on a pay per use or period basis. Even though the importance of IT governance is often underlined, there is limited literature...journal article 2012

Janssen, M.F.W.H.A. (author), Kuk, G. (author)The value of data as a new economic asset class is seldom realized on its own. With less reliance on self-administered survey, it offers new insights into behaviors and patterns. Yet it is a huge undertaking of bringing together multiple actors from different disciplines and diverse practices to examine the underexplored relationships between...journal article 2016

(author)In this letter, we report the observation of ballistic transport on micron length scales in graphene synthesised by chemical vapour deposition (CVD). Transport measurements were done on Hall bar geometries in a liquid He cryostat. Using non-local measurements, we show that electrons can be ballistically directed by a magnetic field (transverse...journal article 2014

Grachev, S.Y. (author), Tichelaar, F.D. (author), Janssen, G.C.A.M. (author)We studied the tensile stress and grain-width evolution in sputter-deposited Cr films with thickness from 20?nm to 2.7??m. Films were deposited in an industrial Hauzer 750 physical vapor deposition machine at 50–80?°C. The films exhibited a columnar microstructure. A power law behavior of the tensile stress as well as of the average grain width...journal article 2005

Zuiderwijk, A.M.G. (author), Helbig, N. (author), Gil-García, J.R. (author), Janssen, M.F.W.H.A. (author)For decades good governance scholarship has focused attention on the importance of government openness [26], [34]. Since the 1960s, Freedom of Information (FOI) legislation has formed the backbone of institutional support for opening information and documents [76] and participatory processes [4], [79]. However, FOI represents a passive approach...journal article 2014
