In this paper we emphasize a similarity between the Logarithmic-Type Image Processing (LTIP) model and the Naka-Rushton model of the Human Visual System (HVS). LTIP is a derivation of the Logarithmic Image Processing (LIP), which further replaces the logarithmic function with a ratio of polynomial functions. Based on this similarity, we show that it is possible to present an unifying framework ...

In this paper, the data assembled concerning the agitation of a Newtonian fluid in a cylindrical vessel is disclosed. The stirred vessel is not provided with baffles and has a flat-bottom. The data presents some information on the characteristics of two impellers: a six-blade Rushton turbine and a six-blade paddle impeller. The flow patterns generated by both impellers are depicted and compared...

ichael Levin’s long-awaited book on race has finally arrived, every bit as powerful and insightful as his admirers had hoped it would be. Why Race Matters does exactly what the title promises—it removes all illusions about the insignificance of race, and explains what racial differences mean for a multi-racial society. It is a thorough, overwhelmingly convincing treatment of America’s most seri...

With progressively brighter stimuli, the amplitude of the photopic b-wave first increases, briefly saturates and then decreases gradually to reach a plateau, where the amplitude of the b-wave equals that of the a-wave; a phenomenon previously presented as the photopic hill. The unique presentation of this luminance-response function seriously complicates its analysis with curve fitting equation...

J. P. Rushton and A. R. Jensen (2005) ignore or misinterpret most of the evidence of greatest relevance to the question of heritability of the Black–White IQ gap. A dispassionate reading of the evidence on the association of IQ with degree of European ancestry for members of Black populations, convergence of Black and White IQ in recent years, alterability of Black IQ by intervention programs, ...

We combine reduced order modeling and system identification to reconstruct the temporal evolution of large-scale vortical structures behind blades a Rushton impeller. performed direct numerical simulations at Reynolds number 600 employed proper orthogonal decomposition (POD) extract dominant modes their coefficients. then applied algorithm, N4SID, construct an estimator that captures relation b...
