“…In 2015, Yang et al [7] put forward a Wi-Fi-based positioning system to provide a much high accuracy in 20/40 MHz bandwidth Wi-Fi applications by considering the bottleneck in time of arrival (ToA) and angle of arrival (AoA) algorithms. In 2017, Pola et al [8] proposed an OFDM-oriented approach using direct signal delay estimation. In the same year, Sultana et al [9] introduced a new tracking system which was equipped with an innovative additional device to combine cellular devices, information and communications technologies (ICTs), indoor and outdoor positioning systems and server software methods to provide the guide service for customers.…”

GPS has a sharp performance decline in terms of accuracy indoors due to the complex building structure. A combined algorithm, targeting at received signal strength indication (RSSI) calibration optimisation, depending on deep neural network training via input vector Γ and the target output vector Ψ, termed reference signal optimisation algorithm (RSOA) is proposed to improve the positioning accuracy in the indoor Bluetooth positioning networks. Experimental results show that the relative error of the proposed RSOA between the estimated results and the measured ones can reach as low as 0.2%, and the absolute errors can be reduced to 0.13 m at most within 10 m.

The construction of quality model for outcome-based education (OBE) Education Mode is an important foundation to guarantee the effective implementation of OBE education reform. The quality model for OBE Education Mode is constructed by layers in this paper according to the reverse design characteristics of OBE Education Mode, which is centred on the students’ learning outcome quality, and in accordance with the closed-loop control requirements for quality. Based on the design of the quality monitoring mechanism, the achievement evaluation mechanism and the feedback and improvement mechanism, a three-dimensional, linked and whole-process quality model system is formed with daily monitoring as the means, the achievement evaluation as the core, the feedback of evaluation result as the focus and the continuous improvement as the goal. Finally, the suggestions are made at the level of implementation to further guarantee the operation effect of the quality model, and so as to offer the important assurance for overall promotion of OBE Education Mode reform.
