Against the range-dependent accuracy of the tracking radar measurements including range, elevation and bearing angles, a new hybrid adaptive Kalman filter is proposed to enhance the performance of the radar aided strapdown inertial navigation system (INS/Radar). This filter involves the concept of residual-based adaptive estimation and adaptive fading Kalman filter and tunes dynamically the fil...

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...

Robots have been used in manufacturing and service industries to improve productivity, quality, and flexibility. Robots are usually mounted on a fixed plate, or on rails, and can move in a limited manner. The success of robots in these environments encourages the use of mobile robots in other applications where the environments are not structured, such as in outdoor environments. This dissertat...

Navigation and positioning technologies play a key role in modern human activities. Currently, navigation devices are mostly dependent on the global satellite systems, for example, system (GPS). However, it is known that GPS signals can be jammed or spoofed otherwise fail. As need independent increases some practical application scenarios, novel techniques based geomagnetic field have been deve...

Abstract The main goal of this paper is estimating certain new fractional integral inequalities for the extended Chebyshev functional in sense synchronous functions by employing proportional (PFI) and Hadamard integral. We establish concerning one- two-parameter integrals. also discuss particular cases.

In this paper, some new results on time-varying missile against a stationary target using pure proportional navigation (PPN) are developed in the planar interception problem. First, relative motion equation is established arc-length domain based differential geometry theory, which eliminates influence of speed. Then, closed-form solution speed intercepting with PPN deduced, and performance anal...
