We introduce a model allowing convenient calculation of the spectral reflectance and transmittance of duplex prints. It is based on flux transfer matrices and enables retrieving classical Kubelka-Munk formulas, as well as extended formulas for nonsymmetric layers. By making different assumptions on the flux transfers, we obtain two predictive models for the duplex halftone prints: the "duplex C...

The modern study of ocean surface waves started with a pioneer study by Sverdrup and Munk (1947). More than half a century has passed since then and the study of ocean surface waves has greatly advanced. The current numerical wave models, supported by many fundamental studies, enable us to compute ocean surface waves on a global scale with sufficient accuracy for practical purposes. However, ph...

This paper is concerned about the estimation of an infinite-dimensional parameter θ0 which is identified via E[ρ(Z, θ0)|W ] = 0 where W is a continuous instrument and ρ(.) a known mapping. Using the principle of Tikhonov regularization developed in Bissantz, Hohage and Munk (2004), a first stage estimator θ̂ minimizing some penalized objective achieves ||θ̂ − θ0|| = Op(n 1 4+γ ) for some positive...

A computer simulation was performed to investigate the optimum combinations of threeand four-chromatic inks in order to maximize the color gamut for halftone printing. A virtual printing model was created based on the YuleNielsen-spectral-Neugebauer equations and Kubelka-Munk turbid media theory and was used to predict the spectral reflectances and colorimetric coordinates of prints. In this ma...

The fate of benzene in the body has been the subject of numerous investigations since 1867 when Schultzen & Naunyn (1867) discovered that benzene was converted to phenol in the animal body. Phenol, catechol, quinol and their conjugates (Munk, 1876; Schmiedeberg, 1881; Nencki & Giacosa, 1880; Baernstein, 1945), muconic acid (Jaffe, 1909; Thierfelder & Klenk, 1924; Drummond & Finar, 1938; Bernhar...

A scanning spectral photometer is deployed on a rigid coastal ocean platform to measure upwelling solar radiances from the sea surface at nine elevation angles spanning 150 degrees of azimuth. Measured radiance distributions at 500 nm wavelength have been compared with traditional model simulations employing the Cox and Munk distribution of wave slopes. The model captures the general features o...

We analyze the effect competition has on the decisions of life insurance companies. In particular, we are interested in the companies’ choices of policy rates and investment strategies given that they have issued contracts with a minimum rate of return guarantee. Our modeling framework is a one-period Cournot model of duopoly. We find policy rates and investment strategies that sustain a Nash e...

We present a new method to estimate color gamut from primary color spectra only. By using this method, the number of prints and measurements for printer characterization is greatly reduced, which is of particular importance if there are many ink candidates to be combined. The method consists in building a mapping between primary color spectra and their combinations, based on a training set. The...

Western countries suggest that a reduction in the number of beds reserved for inpatients may have caused an increase in the need for psychiatric services, particularly among people with schizophrenia (Tsuchiya & Munk-Jørgensen, 2002). The lessons learned from the consequences of deinstitutionalisation need to be considered in countries in which ‘social’ admission prevails and where mental healt...
