Abstract The navigation and positioning subsystem offers important position information for an autonomous underwater vehicle (AUV) system.It plays a crucial role during the underwater exploration and operations of AUV.Many scholars research underwater navigation and positioning.Various improved methods and systems were presented.However, as the div
1-Hydroxy-10-methoxy-dibenz[b,e]oxepin-6,11-dione (1) was obtained from the culture broth of a marine-derived fungus, Beauveria bassiana TPU942, isolated from a marine sponge collected at Iriomote Island in Okinawa, together with two known compounds, Western Hats chrysazin (2) and globosuxanthone A (3).The structure of 1 was elucidated on the basis
Plant-ants live in a Outdoor Fire Pit Table mutualistic association with host plants known as "myrmecophytes" that provide them with a nesting place and sometimes with extra-floral nectar (EFN) and/or food bodies (FBs); the ants can also attend sap-sucking Hemiptera for their honeydew.In return, plant-ants, like most other arboreal ants, protect th
By use of the finite element software Hypermesh and LS-DYNA,the processes were respectively simulated of urban rail vehicle head car,with and without anti-climbing energy absorption device,impacting the fixed rigid wall face to face at the speed of 12.25 km / h and 18 km Munsters / h.Based on the obtained data,the crashworthiness of urban rail vehi
Recently, multi-modal research combining visual and textual information has emerged in Pedestrian Attribute Recognition (PAR).In this field, textual information has primarily been addressed through text modeling using tokenizers and textual Aronia encoders.However, separately learned visual and text encoders often find correlations between visual a
