This work reports on the application of artificial intelligence and neural networks techniques to the problem of trajectory planning and control of a mobile robot with low sensory power. The aim is to determine a spatial sequence through which the robot must navigate forming a trajectory between the starting and goal points. In the first test, the environment has no obstacles and a search tree ...

Vehicle technology has increased rapidly in recent years, particularly in relation to braking system and sensing system. In parallel to the development of braking technologies, sensors have been developed that are capable of detecting physical obstacles, other vehicles or pedestrians around the vehicle. This development prevents accidents of vehicles using Stereo Multi-Purpose cameras, Automate...

the attribute of divine wisdom is applied in shi‘ite theology to prove some religious beliefs. shi‘ite theologians believe that providing the tools needed to achieve the divine purpose of the human beings’ creation and removing the obstacles to it is necessary to god. using logical analyses, this research investigates the sufficiency of the arguments based on divine wisdom in relation to the pr...

Echolocating bats face the challenge of coordinating flight kinematics with the production of echolocation signals used to guide navigation. Previous studies of bat flight have focused on kinematics of fruit and nectar-feeding bats, often in wind tunnels with limited maneuvering, and without analysis of echolocation behavior. In this study, we engaged insectivorous big brown bats in a task requ...

The characteristics and main properties of nucleic acids in general and DNA in particular are described. In addition, their relation to nanoconstruction is given and the main methods, obstacles and breakthroughs during the past ten years are revised. However, the backbone of the essay comprises the work of Seeman's group and their quest for rigidity in nanoconstruction using DNA as a building b...
