Bharosa, N. (author), Janssen, M.F.W.H.A. (author)During crises, relief agency commanders have to make decisions in a complex and uncertain environment, requiring them to continuously adapt to unforeseen environmental changes. In the process of adaptation, the commanders depend on information management systems for information. Yet there are still numerous reports of situations in which...conference paper 2010

Kuiper, E. (author), Van Dam, F. (author), Reiter, A. (author), Janssen, M.F.W.H.A. (author)Cloud adoption in the public sector is taking off slowly, which is perceived as a problem. Models of factors influencing cloud adoption are derived for better understanding using literature and results obtained via desk research and surveys by the Cloud for Europe project. We conclude that several factors require further research, such as the...conference paper 2014

Smit, P.B. (author), Janssen, T.T. (author), Herbers, T.H.C. (author)Refraction of narrow-band surface waves in coastal areas can result in wave-focal zones where due to interference, wave statistics vary rapidly and on similar length scales as those of individual waves. However such interference patterns, or wave coherence, are not accounted for in conventional stochastic wave models that are based on the energy...conference paper 2012

Grünewald, S. (author), Janssen, B. (author), Schipper, H.R. (author), Vollers, K.J. (author), Walraven, J.C. (author)This paper discusses the effect of intentional deformation of a flexible formwork after casting of the concrete and the influence of the characteristics of concrete in the fresh state on the quality of a concrete element. This deformation is intended to bring the concrete element in its desired final shape; the deformation typically takes place...conference paper 2012

Wimmer, M. (author), Codagnone, C. (author), Janssen, M.F.W.H.A. (author)E-government research has become a recognized research domain and many policies and strategies are formulated for e-government implementations. Most of these target the next few years and limited attention has been giving to the long term. The eGovRTD2020, a European Commission co-funded project, investigated the future research on e-government...conference paper 2008

Schipper, H.R. (author), Janssen, B. (author)The manufacturing of double-curved precast concrete elements is still expensive, due to the high costs and limited possibilities for repetitive use of the moulds or formwork. The goal of the research described in this paper is to develop a production method that overcomes these difficulties by enabling the mould to be reused many times and by...conference paper 2011

Janssen, P. (author), Stouffs, R.M.F. (author), Chaszar, A.T. (author), Boeykens, S. (author), Toth, B. (author)This paper describes the use of property graphs for mapping data between AEC software tools, which are not linked by common data formats and/or other interoperability measures. The intention of introducing this in practice, education and research is to facilitate the use of diverse, non-integrated design and analysis applications by a variety of...conference paper 2012

Boella, G. (author), Hulstijn, J. (author), Humphreys, L. (author), Janssen, M.F.W.H.A. (author), Van der Torre, L. (author)Maintaining regulatory compliance is an increasing concern. Legal Knowledge Management systems could support the work of compliance managers. However, there are challenges to overcome, of interpreting legal knowledge and mapping it onto business processes. In this discussion paper we determine requirements for Legal Knowledge Management systems...conference paper 2012

Van Stijn, E.J. (author), Klievink, A.J. (author), Janssen, M.F.W.H.A. (author), Tan, Y. (author)Government agencies and businesses cooperate and invest heavily to achieve reliable and secure global supply networks. A so-called data pipeline, which integrates data from various parties in the supply chain and incorporates data from new tracking and monitoring technologies, would enable real-time data management for businesses. This IT...conference paper 2012

Singerling, T. (author), Klievink, A.J. (author), De Reuver, G.A. (author), Janssen, M.F.W.H.A. (author)Organizations do not just decide on whether or not to exchange information digitally. In many cases, there are multiple alternative configurations of inter-organizational systems (IOS) that facilitate such information sharing. Although a lot is known about the factors that influence whether organizations do or do not adopt IOS, little is known...conference paper 2015

Schipper, H.R. (author), Janssen, B. (author)Free form architecture with complex geometry brings along new challenges for manufacturers of building components. This paper describes the application of structural mechanics to predict the behaviour of an elastic mould surface, used as formwork for the manufacturing of double curved panels in precast concrete. Results are presented of...conference paper 2011

Janssen, M.F.W.H.A. (author), Cresswell, A.

Janssen, M.F.W.H.A. (author), Cresswell, A. (author)Traditionally, government agencies are organized vertically around departments. Many local government agencies are looking for ways to develop an integrated architecture. Many architectural methods are available, however, they remain often abstract, provide limited support for the translation of the concepts to a concrete situation, and have...conference paper 2005

Feenstra, R. (author), Janssen, M.F.W.H.A. (author)New systems can be created by assembling a set of elementary services provided by various stakeholders in a service composition. Service composition is not a trivial endeavor and several composition methods exist. Yet, these methods are hardly adopted by the field, as they need a set of well-defined and welldescribed services and are not able to...conference paper 2009
