'Fast-spike' interneurons of layer 4 mediate thalamocortical feedforward inhibition and can, with some confidence, be identified using extracellular methods. In somatosensory barrel cortex of awake rabbits, these 'suspected inhibitory interneurons' (SINs) have distinct receptive field properties: they respond to vibrissa displacement with very high sensitivity and temporal fidelity. However, th...

In recent years, mobile target localization for enclosed environments has been a growing interest. In this paper, we have proposed a fuzzy adaptive tightly-coupled integration (FATCI) method for positioning and tracking applications using strapdown inertial navigation system (SINS) and wireless sensor network (WSN). The wireless signal outage and severe multipath propagation of WSN often influe...

The grid strapdown inertial navigation system (SINS) used in polar navigation also includes three kinds of periodic oscillation errors as common SINS are based on a geographic coordinate system. Aiming ships which have the external information to conduct a system reset regularly, suppressing the Schuler periodic oscillation is an effective way to enhance navigation accuracy. The Kalman filter b...

Strapdown inertial navigation system/celestial navigation system (SINS/CNS) integrated navigation is a fully autonomous and high precision method, which has been widely used to improve the hitting accuracy and quick reaction capability of near-Earth flight vehicles. The installation errors between SINS and star sensors have been one of the main factors that restrict the actual accuracy of SINS/...

of ours, there immediately springs up a mushroom crop of theorists, who would account, each after his own fashion, for the phenomenon. First come the supernaturalists, who assign the event to the wrath of some offended God or Gods, on account of sins, real or imagined. The " sins of outrulers" is the most favorite formula in India. Next come the transcendentalist s, who attribute the circumstan...

To realize high-precision Single-axial Rotating FOG-SINS, a low-power, low-cost, middle-precision rotating control mechanism design for single axial navigation system is put forward. Through theory analysis, and experimental verification, the has good precision high reliability, which meets demands developing middle & FOG-SINS.
