A novel Tunnel Positioning Approach via Long Term Evolution Cellular Signal

چکیده
Abstract Currently, Radio Frequency Identification System (RFIS), ZigBee and Ultra-Wide Band (UWB) methods are mainly used to positioning in enclosed space. But they require complex hardware layout high costs, resulting the inability meet needs of environments. Therefore, we designed a novel tunnel approach via Long Term Evolution (LTE) cellular signal. This includes: signal acquisition, data preprocessing, feature database construction, model training real-time positioning. In preprocessing stage, adopt 3sigma Kalman filtering filter outliers noise, use information gain rate select effective features. phase, combination K-Weighted Nearest Neighbor (KWNN) Support Vector Regression (SVR) is for tunnel. To verify approach, did an experiment using from actual The experimental results show that this has better accuracy than FK-NN [1] TSVR [2].

The Evolution of Long-term Care Programs; Comment on “Financing Long-term Care: Lessons From Japan”
The need for long-term care (LTC) represents a “new social risk,” one that overlaps with and complements systems of care that pre-date such programs, complicating LTC program design. This commentary expands on Ikegami’s discussion of how these structural factors must be accommodated, as well as historical and cultural factors that influence public expectations of such a...

متن کاملA New Approach for Investigating the Complexity of Short Term EEG Signal Based on Neural Network
Background and purpose: The nonlinear quality of electroencephalography (EEG), like other irregular signals, can be quantified. Some of these values, such as Lyapunovchr('39')s representative, study the signal path divergence and some quantifiers need to reconstruct the signal path but some do not. However, all of these quantifiers require a long signal to quantify the signal complexity. Mate...
متن کاملLong term high tunnel production: Grafting tomatoes
My farm consists of 225 acres on hilly land in Lancaster County, PA. We grow a diversity of crops and our early tomatoes are grown in two acres of multi-bay high tunnels. I reluctantly was forced to fumigate in the tunnels due to problems with verticillium wilt (race 2). At my farm, we have looked at grafting to manage verticillium and other soilborne diseases in our tunnels, and have seen that...

The Unmanned Aerial Vehicles (UAV) positioning in the outdoor environment is usually done by the Global Positioning System (GPS). Due to the low power of the GPS signal at the earth surface, its performance disrupted in the contaminated environments with the jamming attacks. The UAV positioning and its accuracy using GPS will be degraded in the jamming attacks. A positioning error about tens of...
