Accurate indoor position and movement information of devices enables numerous opportunities for location based services. GPS provides accurate localization results in an outdoor environment, however, GPS cannot be applied indoors pervasively due to the various interferences. Although extensive research has been dedicated to this field, accurate indoor location information remains a challenge wi...

The paper deals with utilization of the laser rangefinder for navigation and mapping of unknown indoor environment. Navigation algorithm is based on two pictures comparison of unknown space and gain of the correlation function maximum. The position change (Δx, Δy) of the rangefinder is calculated as a maximum of correlation function. The goal is to improve the accuracy of odometric and inertial...

Indoor air distribution has great impact on people’s thermal sensation. Therefore, how to remove the indoor excess heat becomes an important issue to create a thermally comfortable indoor environment. To expel the extra indoor heat effectively, this paper used a dynamic CFD approach to study the effect of an air-supply guide vane swinging periodically on the indoor air distribution within a mod...
