Janssen, M.F.W.H.A. (author)The service-oriented enterprise (SOE) is often considered as the future model of organization. Yet there is little empirical research in this domain and limited insight into the benefits and disadvantages. In this paper we analyze a case study of a large, multinational banking company. This company is modularized in functions and business...conference paper 2008

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

(author)The growth rate, shoreline reflection, and dissipation of low?frequency waves are investigated using data obtained from physical experiments in the Delft University of Technology research flume and by parameter variation using the numerical model Delft3D?SurfBeat. The growth rate of the shoaling incoming long wave varies with depth with an...journal article 2007

Pujada, B.R. (author), Tichelaar, F.D. (author), Janssen, G.C.A.M. (author)Tungsten carbide-diamond like carbon (WC-DLC) multilayer coatings have been prepared by sputter deposition from a tungsten-carbide target and periodic switching on and off of the reactive acetylene gas flow. The stress in the resulting WC-DLC multilayers has been studied by substrate curvature. Periodicity and microstructure have been studied by...journal article 2007

Janssen, M.F.W.H.A. (author), Hjort-Madsen, K. (author)National enterprise architectures (NEA) promise to fill the gap between policy and implementation. NEAs are embedded within an institutional environment consisting of active players capable of responding strategically and innovatively to architectural initiatives, which might complicate NEA adoption. In this paper we analyze the efforts of two...conference paper 2007

(author)E-government research is currently at a stage of consolidation and new orientation. Smaller steps of government modernization have in part been successfully implemented; larger ones still lie ahead of us. Within an EC funded project, a roadmap for egovernment is being defined. Thereby, scenario building about the future is being used to grasp...conference paper 2007

Janssen, O.T.A. (author), Urbach, H.P. (author), 't Hooft, G.W. (author)The excitation of surface plasmons by subwavelength slits in metal films is studied using a rigorous diffraction model. It is shown that the plasmon is launched by a slit in antiphase with the incident magnetic field. This is true independent of slit width and of the metal used. Using this phase information, maxima and minima in transmission are...journal article 2006

Janssen, G.C.A.M. (author), Tichelaar, F.D. (author), Visser, C.C.G. (author)Stress in hard films is the net sum of tensile stress generated at the grain boundaries, compressive stress due to ion peening, and thermal stress due to the difference in thermal expansion of the coating and substrate. The tensile part due to grain boundaries is thickness dependent. The other two contributions are not thickness dependent....journal article 2006

Janssen, T.T. (author)As ocean surface waves radiate into shallow coastal areas and onto beaches, their lengths shorten, wave heights increase, and the wave shape transforms from nearsinusoidal to the characteristic saw-tooth shapes at the onset of breaking; in the ensuing breaking process the wave energy is cascaded to small-scale turbulent motions in the surf zone....doctoral thesis 2006

Janssen, M.H.A. (author)The beta-lactam antibiotics are the most important class of antibiotics used today. In the last decade the production routes of these antibiotics have shifted from chemical routes to more environmentally benign routes using the enzyme penicillin G acylase. For both practical and economical reasons the enzyme is immobilised. As the kinetically...doctoral thesis 2006

(author)Phase Measurement Interferometers (PMI) are widely used during the manufacturing process of high quality lenses. Although they have an excellent reproducibility and sensitivity, the set-up is expensive and the accuracy of the measurement needs to be checked frequently. This paper discusses an alternative lens metrology method that is based on an...conference paper 2006
