Every year, for ten years now, the IPIN competition has aimed at evaluating real-world indoor localisation systems by testing them in a realistic environment, with movement, using EvAAL framework. The provided unique overview of state-of-the-art systems, technologies, and methods positioning navigation purposes. Through fair comparison performance achieved each system, was able to identify most promising approaches pinpoint critical working conditions. In 2020, included 5 diverse off-site...
The Indoor Positioning and Navigation (IPIN) conference holds an annual competition in which indoor localization systems from different research groups worldwide are evaluated empirically. objective of this is to establish a systematic evaluation methodology with rigorous metrics both for real-time (on-site) post-processing (off-site) situations, realistic environment unfamiliar the prototype developers. For IPIN 2018 conference, was held on September 22nd, 2018, Atlantis, large shopping...
IPIN 2019 Competition, sixth in a series of competitions, was held at the CNR Research Area Pisa (IT), integrated into program Conference. It included two on-site real-time Tracks and three off-site Tracks. The four presented this paper were set same environment, made buildings close together for total usable area 1000 m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> outdoors 6000 indoors over floors, with path length exceeding 500 m....
Indoor positioning is a thriving research area which slowly gaining market momentum. Its applications are mostly customised, ad hoc installations; ubiquitous analogous to GNSS for outdoors not available because of the lack generic platforms, widely accepted standards and interoperability protocols. In this context, Positioning Navigation (IPIN) competition only long-term, technically sound initiative monitor state art real systems by measuring their performance in realistic environment. Most...
A foot-mounted pedestrian dead reckoning system is a self-contained technique for indoor localization. An inertial navigation includes wearable MEMS sensors, such as an accelerometer, gyroscope, barometer, or magnetometer, which enable the measurement of step length and heading direction. In this plan, method based on IMU/EKF+HMM+ZUPT+ZARU+HDR+the Earth Magnetic Yaw was designed to realize navigation. Based characteristics navigation, general likelihood ratio test (GLRT) Hidden Markov Model...
Abstract The epidemic of coronavirus disease 2019 (COVID-19) broke out in Wuhan, China, early 2020. In an effort to curb the spread epidemic, government has requisitioned a variety venues and plant buildings built more than 20 cabin hospitals receive patients with mild symptoms within 48 hours. Under this circumstance, we worked 5G all-wireless solution divide overall network system hospital into multiple units by function. While ensuring good signal coverage local unit, each unit was...
The Zero-velocity Update (ZUPT) aided Extended Kalman Filter (EKF) is commonly used in the classical INS-based foot-mounted PDR (Pedestrian Dead Reckoning) system. However, realistic test, system still often suffers from drift, which mainly caused by two reasons: failed detection of stationary phase dynamic pedestrian gait and heading drift a poorly observable variable ZUPT method. In this paper, order to overcome these problems, three improved constraint algorithms have been proposed...
The inertial-based pedestrian dead reckoning (PDR) system assisted by zero-velocity update (ZUPT) algorithm has been widely researched, as it can independently provide effective pedestrian's position in indoor environment. However, the realistic test, still often suffers from drift, due to ZUPT algorithm's poor observation of system's heading. In this article, based on full analysis existing maximum range constraint between both-side feet, first, a method distance one-side foot proposed. It...
The zero-velocity update (ZUPT)-aided extended Kalman filter (EKF) is commonly used in the traditional inertial navigation system (INS)-based foot-mounted pedestrian dead reckoning (PDR) system, which can effectively suppress error growth of inertial-based systems. However, realistic test, still often suffers from drift, caused by two reasons: failed detection stationary phase dynamic gait and heading a poorly observable variable ZUPT method. In this paper, firstly, order to improve initial...

As the power industry is rapidly developing in China, regional grid interconnections are now under construction. Based on existing planning national configuration, AC/DC coordinated control technology for interconnected developed this paper. By 2013, there have been six High Voltage Direct Current (HVDC) transmission lines delivering from Central China to East China. Ultra (UHV) a series of simulation tests carried out. The following topics investigated paper: 1) How multiple HVDC systems...
As an important passive location method, pedestrian positioning technology plays a large role in indoor scenes and other that cannot be covered by GNSS signals. To enhance the accuracy of mobile phones, geomagnetic matching methods are often used to correct resulting position. However, some methods, such as ICCP, not accurate enough require amount calculation. In meantime, they also lack heading constraint. When magnetic interference is severe, it will have great impact on calculating lead...
Abstract Cu 2 ZnSnS 4 (CZTS) thin film solar cells (TFSCs) have received great attention from the cell industry for their environment, price, high absorption coefficient and electronic properties. This work provides a strategy to prompt photoelectric conversion efficiency (η) of CdS/CZTS-based TFSCs via introducing back surface field (BSF) layer wxAMPS simulate results.

With the large-scale wind power integration, systems have to address not only conventional demand fluctuations but also uncertainty. To improve economical effectiveness, resilience, and environmental protection of in source-load uncertainty, a real-time low-carbon scheduling for wind–thermal–hydro-storage integrated system is proposed. The imbalance caused by uncertainty neutralized synergetic linear decision multiple resources. stochastic robust optimization introduced, which establishes...
Abstract Rosa laevigata Michx., a member of the Rosaceae family, is famous traditional Chinese medicine and edible food in Asian countries. The major active ingredient triterpenoid, which has anti‐Alzheimer's Disease (AD), antioxidant neuroprotection properties.
