Self-driving cars have experienced rapid development in the past few years, and Simultaneous Localization Mapping (SLAM) is considered to be their basic capabilities. In this article, we propose a direct vision LiDAR fusion SLAM framework that consists of three modules. Firstly, two-staged visual odometry module, which frame-to-frame tracking step, an improved sliding window based thinning prop...

Salinization is the main characteristic of soils in arid and semi-arid regions which reduce the agricultural potential ofirrigated lands. Therefore, soil reclamation as well as determination of the leaching requirement for salt control is veryimportant for better plant growth. In this study, the effects of leaching on saline soils of Sistan region, southeast of Iranwere examined using unsaturat...

The majority of hydraulic processes under a natural condition in a field are carried out under unsaturated flow conditions. The soil moisture retention curve (SMRC) is the most important hydraulic characteristic of an unsaturated soil whose knowledge is of prime importance in soil-water studies such as soil conservation, soil erosion, land evaluation, soil reclamation, and water resources manag...

The available status of Fe, Mn, Cu and Zn in two soils (Melandaha-Silt loam Dhamrai-Silty clay loam) was determined by extraction methods (0.5 M DTPA 0.1 N HCI). previously treated with various composts and/or compost plus fertilizer Amaranthus grown upto 42 days. After harvest Amaranthus, the were extracted 0.5 HCI extracts analyzed for trace elements contents. availability varied significantl...

Zinnia elegans, an annual flowering plant of the genus Zinnia, is one of the best known zinnias. Present study was conducted to evaluate the effect of different growing media on the growth and flowering of Zinnia elegans. Seven different growth media including coconut compost, silt, soil loam, leaf manure, (leaf manure + silt; 2:1), (coconut compost + soil loam; 1:1) and (leaf...
