This paper presents a novel method of combining topological and feature-based mapping strategies to create a hierarchical approach to simultaneous localization and mapping (SLAM). More than simply running both processes in parallel, we use the topological mapping procedure to organize local feature-based methods. The result is an autonomous exploration and mapping strategy that scales well to l...

In this paper, we propose a composite Laguerre-Legendre pseudospectral method for exterior problems with a square obstacle. Some results on the composite Laguerre-Legendre interpolation, which is a set of piecewise mixed interpolations coupled with domain decomposition, are established. As examples of applications, the composite pseudospectral schemes are provided for two model problems. The co...

Un ultimo ringraziamento va a Lui, non si gioca a dadi qui, c'` e il Suo sogno per ognuno di noi, a noi non resta che viverlo.

Background and Objectives: Given the limited number of studies on Ramadan fasting and military performance, we conducted this study to identify the effect of Ramadan fasting on physical fitness performances in army cadets. Methods: Twenty healthy males were randomly selected from a larger sample group. The subjects were divided into fasting (n=10) and non-fasting (n=10) groups. They performed v...

Abstract In this paper, we give an a posteriori error estimates with constitutive law for some obstacle problem. The error estimator involves some parameter ε appeared in some penalized equation.

The aim of a soccer game is to score more goals than the opponent does. The chances of doing so increase when all the own players are continuously present on the field. In the RoboCup Standard Platform League (SPL), the only reasons for players not to participate in a game are that they either have been penalized or they have not been ready for the match in the first place. This paper presents ...
