Integrating and differentiating matrices allow the numerical integration and differentiation of functions whose values are known at points of a discrete grid. Previous derivations of these matrices have been restricted to one-dimensional grids or to rectangular grids with uniform spacing in at least one direction. The present work develops integrating and differentiating matrices for grids with...

A numerical simulation has been conducted to investigate the oscillatory mechanism of a solutocapillary convection and influence different aspect ratios on flow characteristics in liquid bridge. The SIMPLE algorithm is applied figure out Navier-Stokes equation concentration diffusion staggered grids, level set approach with conservation mass used acquire surface deformation are analyzed detail,...

One of the more valuable and flexible forms of knowledge acquisition is based upon the use of repertory grids. A useful extension of repertory grids can be created by providing a method of semantically linking associated constructs and repertory grids. This network of grids is a semantic network with nodes consisting of individual repertory grids and links acting as ‘tracks.’ A track is a gener...

objective: the purpose of this study was to evaluate the transverse strength of one brand of denture base material repaired with two autopolymerized acrylic resins with and without wire reinforcement. materials and methods: eighty samples (2.5×10×65 mm3) were fabricated and divided into five groups. the control group was left intact. groups b and d specimens were repaired with autopolymerizing ...

We study how the underlying graph of dependencies of one dimensional cellular automaton may be used in order to move and compose areas of computations. This allows us to deene complex cellular automata, relaxing in some way the inherent synchronism of such networks. and asynchronous computations. R esum e Nous etudions comment le graphe sous-jacent de d ependances d'un automate cellulaire de di...

A 2D grid is a particular geometric graph that may be used to represent any 2D regular structure such as, for example, pixel grids, game boards, or cellular automata. Pattern mining techniques may be used to automatically extract interesting substructures from these grids. 2D+t grids are temporal sequences of grids which model the evolution of grids through time. In this paper, we show how to e...

In this article, we propose to investigate the extension of the SEDT (Squared Euclidean Distance Transformation) on irregular isothetic grids. We give two algorithms to handle different structurations of grids. We first describe a simple approach based on the complete Voronoi diagram of the background irregular pixels, very fast on sparse grids. Then, we extend the separable algorithm defined o...

We discuss the generation of curvilinear composite overlapping grids and the numerical solution of partial differential equations on them. A composite overlapping grid consists of a set of curvilinear component grids that cover a region and overlap where they meet. Continuity conditions (interpolation) are imposed at the overlapping boundaries. The principal advantage of composite grids is in t...

The dorsomedial entorhinal cortex (dMEC) of the rat brain contains a remarkable population of spatially tuned neurons called grid cells (Hafting et al., 2005). Each grid cell fires selectively at multiple spatial locations, which are geometrically arranged to form a hexagonal lattice that tiles the surface of the rat's environment. Here, we show that grid fields can combine with one another to ...

this paper proposes an optimal power flow (opf) algorithm by direct load control (dlc) programs to optimize the operational cost of smart grids considering various scenarios based on different constraints. the cost function includes active power production cost of available power sources and a novel flexible load curtailment cost associated with dlc programs. the load curtailment cost is based ...
