Download or read book Multipath Exploitation for Emitter Localization using Ray Tracing Fingerprints and Machine Learning written by Marcelo Nogueira de Sousa and published by BoD – Books on Demand. This book was released on 2021-01-01 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: The precise localization of radio frequency (RF) transmitters in outdoor environments has been an important research topic in various fields for several years. Nowadays, the functionalities of many electronic devices are based on the position data of a radiofrequency transmitter using a Wireless Sensor Network (WSN). Spatially separated sensor scan measure the signal from the transmitter and estimate its location using parameters such as Time Of Arrival (ToA), Time Difference Of Arrival (TDOA), Received Signal Strength (RSS) or Direction Of Arrival (DOA). However, certain obstacles in the environment can cause reflection, diffraction, or scattering of the signal. This so called multipath effect affects the measurements for the precise location of the transmitter. Previous studies have discarded multipath information and have not considered it valuable for locating the transmitter. Some studies used ray tracing (RT) to create position fingerprints, without reference measurements, in a simulated scenario. Others tested this concept with real measurement data, but this proved to be a more cumbersome method due to practical problems in the outdoor environment. This thesis exploits the concept of Channel Impulse Response (CIR) to address the problem of precision in outdoor localization environments affected by multipath. The study aims to fill the research gap by combining multipath information from simulation with real measurements in a machine learning framework. The research question was whether the localization could be improved by combining real measurements with simulations. We propose a method that uses the multipath fingerprint information from RT simulation with reference transmitters to improve the location estimation. To validate the effectiveness of the proposed method, we implemented a TDoA location system enhanced with multipath fingerprints in an outdoor scenario. This thesis investigated suburban and rural areas using well-defined reflective components to characterize the localization multipath pattern. The results confirm the possibility of using multipath effects with real measurements to enhance the localization in outdoor situations. Instead of rejecting the multipath information, we can use them as an additional source of information.

Download or read book Geological Disasters in Deep Engineering Mechanism Warning and Risk mitigation written by Guang-Liang Feng and published by Frontiers Media SA. This book was released on 2023-06-15 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the increasing demand for infrastructure construction as the global economy progresses, the need for exploration and utilization of deep underground space becomes more crucial. Various deep underground projects are planned, are under construction, and have been built to encounter great construction challenges due to the complex geo-environment such as strong tectonic movement, fragile geo-environment and complex thermo-hydro-mechanical-chemical conditions. These deep engineering projects could be endangered by different kinds of geological disasters, such as intense rockburst, large deformation, strong water inrush, and large-scale collapse, which might result in massive loss of life and economic damage during the construction of deep underground projects. It is necessary to take proactive measures to ensure that the development of deep engineering projects is risk-informed and sustainable. Efforts are being called for strengthening science and technology innovation and cooperation in geological disaster mitigation and sustainable development during the construction of deep engineering projects. It is paramount to use new technologies and international cooperation to jointly tackle the geological disasters risks and achieve sustainable development. To mitigate the risk of geological disaster in deep engineering under the complicate geo-environment, the mechanism of the formation and evolution of geological disasters in deep engineering needs to be understood. The testing, monitoring, simulation, risk assessment and early warning methods for geological disaster in deep engineering are also needed urgently. New theories, methods and techniques related to the mechanism, warning and risk mitigation of geological disasters in deep engineering will be extremely helpful for the construction safety of deep engineering.
