It is known that ants learn long visually guided routes through complex terrain. However, the mechanisms by which visual information is first learned and then used to control a route direction are not well understood. In this article, we propose a parsimonious mechanism for visually guided route following. We investigate whether a simple approach, involving scanning the environment and moving i...

The motion mechanisms of manufacturing and robotic systems are developed in different structures, mainly cartesian delta structures having series or parallel movement abilities according to the capacity construction structure system. Different used criteria such as bearing load capacity, sensitivity cost In this study, performances machines installed kinematic which mostly three - dimensional p...

We describe a method for independently verifying the dose distributions from pre- and post-implant brachytherapy source distributions. Monte Carlo calculations have been performed to characterize the three-dimensional dose distribution in water phantom from a low-energy brachytherapy source. The calculations are performed in a voxelized, Cartesian coordinate geometry and normalized based upon a...

We generalize Schrödinger’s factorization method for Hydrogen from the conventional separation into angular and radial coordinates to a Cartesian-based factorization. Unique this approach is fact that Hamiltonian represented as sum over factorizations in terms of coupled operators depend on momenta each Cartesian direction. determine eigenstates energies, wavefunctions both coordinate momentum ...

We consider sparse matrices arising from nite-element or nite-diierence methods. The graphs of such matrices are embedded in two or three dimensional Euclidean space, and the coordinates of their vertices are readily available. Such coordinate information was used earlier to develop a parallel Cartesian nested dissection heuristic that computes a ll reducing ordering for a matrix with an embedd...

In this paper a new approach to iterative learning control for the practically relevant case of deterministic discrete linear plants with uniform rank greater than unity is developed. The analysis is undertaken in a 2D systems setting that, by using a strong form of stability for linear repetitive processes, allows simultaneous consideration of both trial-to-trial error convergence and along th...

In this paper, we describe a modular software that allows fast development of eye-in-hand image-based visual servoing applications (ViSP states for “Visual Servoing Platform”). Visual servoing consists in specifying a task as the regulation in the image of a set of visual features. Various issues have thus to considered in the design of such application: among these issues we find the control o...

Iterative learning control is a technique especially developed for application to processes which are required to repeat the same operation over a finite duration. The exact sequence of operation is that the task is completed, the process is reset and then the operation is repeated. Applications are widespread among many industries, e.g. a gantry robot which is required to place items on a conv...
