For robots navigating using only a camera, illumination changes in indoor environments can cause re-localization failures during autonomous navigation.In this paper, we present a multi-session visual SLAM approach to create a map made of multiple variations of the same locations in different illumination conditions.The multi-session map can then be

In the title compound, C19H36N3+·I−, the orientation of the cyclohexyl rings around the planar (sum of N—C—N angles = 360°) CN3+ unit produces steric hindrance around the N—H groups.As a consequence of this Hitting Strip particular orientation of the tricyclohexylguanidinium cation (hereafte
Soil moisture and salinity measurement are the essential factors for crop irrigation as well as to increase the yield.Grapes eminence depends on the water volume contents in soil and soil nutrients.Based on these conditions, we determined water demand for best quality of grapes Massagers by wireless sensor network (WSN).Using lot of chemical fertil
Presence of plastics in the surroundings is ubiquitous, as generation of plastics is booming globally and it gets accumulated in oceans leading to deleterious impacts on marine life, public health and the surrounding environment.Owing to its non-degradable nature, plastic particles remain in surroundings for extended periods which automatically fac
