Abstract-Indoor positioning systems based on Wireless LAN (WLAN) are being widely investigated in academia and industry. Meanwhile, the emerging low-cost MEMS sensors can also be used as another independent positioning source. In this paper, we propose a pedestrian tracking framework based on particle filters, which extends the typical WLAN-based indoor positioning systems by integrating low-cost MEMS accelerometer and map information. Our simulation and real world experiments indicate a remarkable performance improvement by using this fusion framework.
Control of the clutch position is a crucial point for automating manual transmissions. Here, an electrohydraulic clutch position control system is considered. Based on the flatness approach, a nonlinear feedforward control is designed, which is combined with a linear feedback control and implemented on a standard transmission control unit. Experiments with a Mercedes-Benz Sprinter and a Mercedes-Benz CLK prove that this new control system is significantly superior to conventional control concepts, and provides an accurate trajectory tracking of the clutch position.
In this paper the integration of an excessive share of distributed generation into a T&D system in the southern part of Germany has been examined. Various solutions like conventional network extension, energy storage, load management and controllable smart grid components are compared in terms of number of assets and investment costs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
