Fysisch en Elektronisch Laboratorium TNO (author), B. Schwering, Piet (author)Observations in the infrared wavelength band between 8 and 12 μm of sea backgrounds have been recorded with a CCIR compatible imager for a large number of sea states (0 - 6). Recordings took place in coastal areas as well as on open seas. The behavior of clutter in the infrared data was analyzed in space and in time. Clutter values are analyzed...conference paper 1991

Brem, G. (author), Instituut voor milieu- en energietechnologie TNO (author)The main goal of the present thesis is to develop mathematical models for coal conversion processes, to improve the understanding of the underlying physical processes and to support the experimental work in the fieId. Therefore, emphasis is given on developing analytical descriptions for variables involved with conversion of solid particlesin a...doctoral thesis 1990

Toet, A. (author)A hierarchical image fusion scheme is presented that preserves those details from the input images that are most relevant to visual perception. Results show that fused images present a more detailed representation of the scene and provide information that cannot be obtained by viewing the input images separately. Detection, recognition, and...article 1990

Fysisch en Elektronisch Laboratorium TNO (author), Meiler, P.P. (author)FEL heeft een SPR (Spatio-temporeel Pattern Recognition) neuraal nerwerk geïmplementeerd om vervormde woorden en/of delen van zinnen, in dit geval de namen van schepen, te herkennen in een real-time toepassing. Deze namen kunnen vervormd worden door transmissie en/of type fouten. SPR legt de nadruk op de volgorde van de karakters in een woord....conference paper 1990

Medisch Biologisch Laboratorium TNO (author), van der Drift, A.C.M. (author), van Noort, J.M. (author), Krüse, J. (author)Processing of most exogenous protein antigens involves restricted intracellular proteolysis to yield fragments that may be bound specifically by MHC class II glycoproteins. This association is required for functional presentation to antigen-specific T lymphocytes. The proteolytic degradation takes place in antigen-presenting cells, in an acidic,...article 1990

van der Horst, A.R.A. (author), Godthelp, J. (author), Instituut voor Zintuigfysiologie TNO (author)The limitations of human information processing capabilities are apparent in modern road traffic. Research methods for studying road user behavior range from unobtrusive observations of actual traffic to highly controlled laboratory experiments. Often the incompatibility between controllability and validity makes the choice of a suitable method...conference paper 1989

Medisch Biologisch Laboratorium TNO (author), van Noort, J.M. (author), van der Drift, A.C.M. (author)The selectivity of cathepsin D, a mammalian intracellular aspartyl proteinase involved in the degradation of endocytosed proteins, was studied. For this purpose, several proteins of known primary structure were subjected to mild proteolysis by the enzyme, and the preferentially cleaved peptide bonds were identified. Comparison of the primary...article 1989

Hoogeboom, P. (author)In The Netherlands a digltal SLAR system (X-band)is used since many years in the radar remote sensing research. This system supports research Programs in which also other equipment is used, for instance a multiband airborne scatterometer. Based on our experience in radar remote sensing a polarimetric C-band aircraft SAR is designed, to be...article 1988

Steeneken, H.J.M. (author), Instituut voor Zintuigfysiologie TNO (author)An attempt was made to obtain, from two subjective and one objective intelligibility measures, additional information concerning the type of deterioration the speech signal was subjected to. For this method a data reduction of the original phoneme scores and phoneme confusions was applied. This procedure was also performed for an objective ...conference paper 1987

Instituut voor Zintuigfysiologie TNO (author), Godthelp, J. (author)This paper presents two experiments in which steering a lane-change manoeuvre is analysed as a precognitive control task. The suggestion that the dependence on instantaneous visual feedback is low during such a task was tested by analysing steering performance under conditions both with and without visual occlusion. Steering force served as the...article 1985

Hoogeboom, P. (author), Physisch Laboratorium TNO (author)Studies on microwave surface scattering in The Netherlands have indicated the need for accurate radar systems for applications in remote sensing. An SLAR system with digital recording was developed and is now being used for several programmes. This system was designed with special attention to speckle reduction and system accuracy. The digital...article 1983

Hoogeboom, P. (author), Binnenkade, P. (author), Veugen, L.M.M. (author)In The Netherlands an accurate SLAR system with digital data recording is used for measurements within the framework of the national microwave remote sensing research program. However, the images are disturbed by unwanted platform motions due to, e.g., turbulence at the low operating height (300–3000 m) of the SLAR system. An algorithm is...conference paper 1983
