Abstract It is of great significance to locate faults quickly and accurately in power distribution system improve reliability recover quickly. With high positioning accuracy, strong anti-interference ability mountainous areas cities, the provide all-weather all-round services, BeiDou-3 (BD3) navigation satellite has broad application prospects systems. Using filtering principle normalized least...

This paper investigates the problem of impact-time-control and proposes a learning-based computational guidance algorithm to solve this problem. The proposed is developed based on general prediction-correction concept: exact time-to-go under proportional navigation with realistic aerodynamic characteristics estimated by deep neural network biased command nullify impact time error utilizing emer...

the most current pursuit algorithms for moving targets which are presented so far in the literatureare pure pursuit and pure rendezvous navigations. recently, one of the present authors has introduced ageometric model for the pure pursuit navigation algorithm. here, in this paper, we study a new algorithm forthe pursuit navigation problem which is a combination of both of the above algorithms. ...

Recent advances in small, low cost satellite technology has generated a renewed interest in formation flying missions. One challenging aspect of satellite formation flying missions is collision free navigation and control. In this paper, novel robust control algorithm using Sliding Mode Control is presented for a threedimensional, high Earth orbit satellite formation scenario. The paper present...

The aim of the present study was to evaluate the effect of melatonin as an antioxidant on spatial navigation memory in male diabetic rats. Thirty-two male white Wistar rats weighing 200 ± 20 g were divided into four groups, randomly: control, melatonin, diabetic and melatonin-treated diabetic. Experimental diabetes was induced by intraperitoneal injection of 50 mg kg-1 streptozotocin. Melatonin...

In this paper, a new method was proposed for the navigation of a mobile robot in an unknown dynamic environment. The robot could detect only a limited radius of its surrounding with its sensors and it went on the shortest null space (SNS) toward the goal. In the case of no obstacle, SNS was a direct path from the robot to goal; however, in the presence of obstacles, SNS was a space around the r...
