Bethylidae are cosmopolitan wasps, with about 100 valid genera and about 2,400 valid species around the world, with 39 genera recorded from the Afrotropical region.This study aimed to determine the genera of Bethylidae occurring in Madagascar.The specimens were collected in Madagascar with 158 several traps.A total of 18,915 specimens were obtained
Topic models and neural networks can discover meaningful low-dimensional latent representations of text corpora; as such, they have become a key technology of document representation.However, such models presume all documents are non-discriminatory, resulting in latent representation dependent upon all other documents and an inability to provide di
This paper discussed the stabilization and position tracking control of the linear motion of an underactuated spherical robot.By considering the actuator dynamics, a complete dynamic model of the robot is Winch Bumper deduced, which is a complex third order, two variables nonlinear differential system and those two variables have strong coupling du
