This work presents a solution to localize Unmanned Autonomous Vehicles with respect to pipes and other cylindrical elements found in inspection and maintenance tasks both in industrial and civilian infrastructures.The proposed system exploits the different features of vision and laser based sensors, combining them to el reformador tequila anejo obt
Traditional flexure hinges are designed by using a single material, and their performance is inadequate, compared to the ideal hinge.This paper presents a topology-optimization design method for multi-material flexure hinges based on the element stacking method.A topology optimization model for multi-material flexure hinges is constructed to find t
Varanids are the only non-avian sauropsids that are known to approach the warm-blooded mammals in stamina.Furthermore, a much higher maximum metabolic rate (MMR) gives wonderstruck enchanted endotherms (including birds) higher stamina than crocodiles, turtles, and non-varanid lepidosaurs.This has led researchers to hypothesize that mammalian endoth
Dasiphora fruticosa comprises male, female and hermaphrodite plants, which are distributed sympatrically in some populations on the Qinghai-Tibet Plateau.To explore what governs the coexistence of these three sexual phenotypes, we investigated the DNA contents, pollen and ovule production, pollen deposition, and performed hand-pollination knesko co
