or facial 3-D relief) is introduced by using the range image. We propose a method to generate a facial caricature depending on a simple method for corresponding 3-D facial images. In this method, we extract several facial parts regions each of which include facial parts of the face by using both gray and range images. The diagonal comers of the respective extracted regions are used to provide t...

We outline the regions in the parameter space of a model of cardiac excitation where normal 1:1 response, alternans 2:2 response and further instabilities occur during repeated stimulation with a dynamic restitution pacing protocol. To this end we consider a version of the classical model of Purkinje fibers (Noble, J. Physiol. 160:317, 1962) simplified by a well-justified asymptotic embedding a...

The question whether a caricature of a 2D sketch, or an object in 3D can be generated automatically is probably as old as the attempt to answer the question of what defines art. In an attempt to provide a partial answer, we propose a computational approach for automatic caricaturization. The idea is to rely on intrinsic geometric properties of a given model that are invariant to poses, articula...

Abstract This article discusses the Ivorian writer, Fatou Fanny-Cissé’s novel, Madame la présidente , published in 2015. The novel offers a fundamental critique of African democracy and contemporary politics Africa.

We extend a nonstandard asymptotic method proposed earlier, for calculation of conduction velocity restitution curves in ionic models of cardiac excitability. Conduction velocity restitution is the simplest nontrivial spatially extended problem in excitable media, and in the case of cardiac tissue it is an important tool for prediction of cardiac arrythmias and fibrillation. An idealized conduc...

We extend a non-Tikhonov asymptotic embedding, proposed earlier, for calculation of conduction velocity restitution curves in ionic models of cardiac excitability. Conduction velocity restitution is the simplest non-trivial spatially extended problem in excitable media, and in the case of cardiac tissue it is an important tool for prediction of cardiac arrhythmias and fibrillation.

We propose a method to generate a facial caricature depending on a simple methodfor corresponding 3-D facial images. In this method, we extract several facial parts regions each of which include facial parts of the face by using both gray and range images. The diagonal corners of the resp,ctive extracted regions are used to provide the informations on the correspondence between the faces. There...

Abstract The subject of this article is the evolution Soviet political caricature as reflected in work artist Boris Efimov. focuses on post-revolutionary period Efimov’s career up to eve World War II , with particular attention changes his following Stalin’s consolidation dictatorial power by early 1930s. While examining nature several key caricatures Efimov 1920s and 1930s, also considers cont...
