In the field of autonomous driving, the correct detection of traffic signs can provide important information for environmental perception.To address the low recognition rate and misdetection and missed detection issues of various traffic signs, we propose a coordinate attention - bidirectional feature pyramid network (CA-BIFPN) traffic sign detecti
Lake Onega is located in the southern part of Karelia, in the north-west of Russia.We report data taken by various limnigraphs and current meters and isolate, by spectral analysis, the most conspicuous barotropic periods of these signals.The analysis that follows is based on the linearized shallow-water equations, ACIDIC STOMACH ALKALINE BALANCE th
The harmonic drive (HD) is increasingly used due to its outstanding advantages, especially for equipment requiring high precision and a large gear ratio.This research is based on the Finite Element Method (FEM) and mechanical analysis to investigate stress calculation methods for the flexspline (FS), a significant component of HD transmission, prov
Warm Mix Asphalts (WMAs) are asphalt concretes produced at lower temperatures than traditional Hot Mix Asphalts (HMAs).Nonetheless, the above is not enough to diminish the environmental impacts associated with the road infrastructure industry.Accordingly, incorporating Recycled Concrete Aggregate (RCA) as a partial replacement for Natural Aggregate
