For viscous conservation laws, solutions contain smooth but high-contrast features, which require the use of fine grids to properly resolve. On coarse grids, these high-contrast jumps resemble shocks rather than their true viscous profiles, which could lead to issues in the numerical approximation of their underlying dynamics. In many cases, the equations of motion emit traveling wave solutions...

We consider a L-contraction (a L-type stability) of large viscous shock waves for the multi-dimensional scalar viscous conservation laws, up to a suitable shift. The shift function, depending both on the time and space variables, solves a viscous HamiltonJacobi equation with source terms. We consider a suitably small L-perturbation around a viscous planar shock wave with arbitrarily large stren...

| A simple approach to compute the skeletons of gray-scale images using partial di erential equations is presented in this paper. The proposed scheme works directly on the gray-scale images, without the necessity of pre-segmentation (binarization), or the addition of shock capturing schemes. This is accomplished by deforming the given image according to a family of modi ed continuousscale erosi...

The dynamics of one-dimensional, overdriven, hydrogen-air detonations predicted in the inviscid limit as well as with the inclusion of mass, momentum, and energy diffusion were investigated. The effect of resolution was studied for both shock-capturing and shockfitting in the inviscid limit, and it was found that shock-capturing required four times the amount of resolution of shock-fitting to p...

The process of specifying an embedded system involves capturing complex interrelationships between the hardware domain, the software domain, and the engineering domain used to describe the environment in which the system will be embedded. Developers increasingly turn to domain-specific modeling techniques to manage this complexity, through such approaches as Model Integrated Computing and Model...

MUVIS is a series of CBIR systems. The first one has been developed in late 90s to support indexing and retrieval in large image databases using visual and semantic features such as color, texture and shape. During recent years, MUVIS has been reformed to become a PCbased framework, which supports indexing, browsing and querying of various multimedia types such as audio, video, audio/video inte...

Standard likelihood-based frameworks in phylogenetics consider the process of evolution of a sequence site by site. Assuming that sites evolve independently greatly simplifies the required calculations. However, this simplification is known to be incorrect in many cases. Here, a computational method that allows for general dependence between sites of a sequence is investigated. Using this metho...

This paper discusses some implications of knowledge creation processes in informal social networks for the development of technologies to support them. The principal point of departure are social theories of learning and the theories of organisational knowledge creation. The focus is on models for the exchange and sharing of implicit knowledge. A model of personalised learning knowledge maps is...

The asymmetrical subterfuge anthropomorphizes a simmering 3D motion of hand that is espoused to a predictable outline which classifies the Xography for signal appreciation of video games. The hand can be trademarked into numerous signal brochures or in uncommon movement trails. This gearshift the evolution of video games built on Xography for hand trailing and signal appreciation method. Essent...

The models of the evolution researchers are focused on the origin and the multiplication of organisms. This paper introduces a possible approach of the evolution of organisms being concerned in the appearance of the intelligence. This process is self developing and adaptive, producing the knowledge graph, which is the result of a lifelong data capturing and acquisition task of an artificial dig...
