This paper presents an enhanced Simultaneous Localization and Mapping (SLAM) framework for mobile robot navigation.It integrates RGB-D cameras and 2D LiDAR sensors to improve both mapping accuracy and localization efficiency.We propose a data fusion strategy where RGB-D point clouds are projected into 2D and denoised alongside LiDAR data.Late fusio

We review the lines of evidence that some cataclysmic variables (CVs) are the sources of non-thermal radiation.It was really observed in some dwarf novae in outburst, a novalike CV in the high state, an intermediate polar, polars, and classical novae (CNe) during outburst.The detection of this radiation suggests omnipure q5633 the presence of highl

In recent studies, vapour transfer is reported to lead to remarkable frost heave in unsaturated soils, but how to better model this process has not been answered.In order to avoid the great uncertainty caused by the phase change term of vapour-water-ice in the numerical iteration process, a new numerical model is developed based on the coupled ther

In recent years, as number of new building getting larger, there has been an increased interest in the cleaning of exterior walls.Accordingly, there is a growing interest in automatic cleaning robots that move around the outer building façade.These robots are also required to apply different cleaning methods to remove various contaminants on

The article is devoted to the problems of racial discrimination and the anti-segregation struggle for the rights of Black citizens in American society.This problem remains relevant despite the successes of the civil rights movement and the activities of many organizations in support of e. cuarenta cerveza the Coloured population.In this regard, the
