Braat, J.J.M. (author), Dirksen, P. (author), Janssen, A.J.E.M. (author), Van Haver, S. (author), Van de Nes, A.S. (author)The judgment of the imaging quality of an optical system can be carried out by examining its through-focus intensity distribution. It has been shown in a previous paper that a scalar-wave analysis of the imaging process according to the extended Nijboer–Zernike theory allows the retrieval of the complex pupil function of the imaging system,...journal article 2005

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

Janssen, M.F.W.H.A. (author), Cresswell, A. (author)Achieving goals of better integrated and responsive government services requires moving away from stand alone applications toward more comprehensive, integrated architectures. As a result there is mounting pressure to move from disparate systems operating in parallel toward a shared architecture designed to support information exchange and cross...conference paper 2005

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

Janssen, G.C.A.M. (author), Kamminga, J.D. (author)In the absence of thermal stress, tensile stress in hard metal films is caused by grain boundary shrinkage and compressive stress is caused by ion peening. It is shown that the two contributions are additive. Moreover tensile stress generated at the grain boundaries does not relax by ion bombardment. In polycrystalline hard metal films the grain...journal article 2004

Dirksen, P. (author), Braat, J. (author), Janssen, A.J.E.M. (author), Leeuwestein, A. (author), Kwinten, H. (author), Van Steenwinckel, D. (author)This study presents an experimental method to determine the resist parameters that are at the origin of a general blurring of the projected aerial image. The resist model includes the effects of diffusion in the horizontal plane and a second cause for image blur that originates from a stochastic variation of the focus parameter. The used...conference paper 2004

Janssen, G.C.A.M. (author), Dammers, A.J. (author), Sivel, V.G.M. (author), Wang, W.R. (author)Thin films on substrates are usually in a stressed state. An important, but trivial, contribution to that stress stems from the difference in thermal expansion coefficient of substrate and film. Much more interesting are the intrinsic stresses, resulting from the growth and/or microstructure of the film. Intrinsic compressive stress was...journal article 2003

Schokking, L.A. (author), Janssen, P.C. (author), Verhagen, H.J. (author)The stability of stones in propeller-induced jet wash is still difficult to predict. Especially the trend of bowthrusters increasing in size and power in sea going ships (especially ferries) over the last years may be a reason for concern when dealing with the protection of slopes and beds. But also ships used in inland navigation are using...journal article 2003
