GNSS/INS integrated navigation and positioning technology is widely used for train operations applications seeking a decrease in dependence on trackside equipment. However, during operations, environmental factors such as bridges, tunnels, hillsides, buildings will block the satellite signals. When INS works stand-alone mode, system errors accumulate with time due to inertial sensor characteristics. To overcome this problem, light detection ranging (lidar) equipment can be introduced help...
Abstract This paper presents a robust train localisation system by fusing Global Navigation Satellite System (GNSS) with an Inertial (INS) in tightly-coupled (TC) strategy. To improve navigation performance GNSS partly blocked areas, advanced map-matching (MM) measurement-augmented TC GNSS/INS method is proposed via error-state unscented Kalman filter (UKF). The MM generates matched position using one-step predicted from UKF time update step binary search algorithm and point–line projection...
Compared with pseudorange measurement, carrier phase tracking is much less noisy, which can provide accurate positioning solutions. The existing phase-based methods rely on precise ephemeris or base station, may cause poor real-time and increase complexity in the system. To simplify calculation model achieve navigation solutions a stand-alone receiver, new GPS/BDS based non-differential method proposed. Due to need estimate ambiguity terms of measurements, dimension state larger than that...
Due to the high cost and complex challenges faced by offshore wind power transmission, economic research into transmission can provide a scientific basis for optimal decision-making on projects. Based analysis of topology structure characteristics typical schemes, this paper compares benefits five different schemes with 3.6 GW sizeable onshore farm as primary case. Research includes traditional voltage alternating current (HVAC), source converter direct (VSC-HVDC), fractional frequency...
A Rough Set&Feature Weighted Support Vector Machine(RS-FWSVM) model is proposed for the quality of supply chain crisis early-warning, which aims at some problems chain. This combines advantages RS and FWSVM, can get classification per-formances by changing weights different linear functions in feature space. Application process this to early warning SCQ researched, help enable enterprises identify crises operations predict possible crises.
A new zero-bias model and compensation procedure for the intermediate frequency (IF) signal processing system of vector network analyzer (VNA) based on neural is proposed in this paper. This can be used to four IF channels with different conditions. The structure one port given first. Then channels, same method applied. modeled by radial basis function compensated via analysis model. Finally, tested AV3672 series VNA experiment shows that well eliminate signal, it effective compensation.
GNSS/INS integration is widely used for train positioning, but railways tunnels and mountains can interfere GNSS signals will lead to performance degradation when the system operated in standalone INS mode. This paper proposes a Long Short Term Memory (LSTM)-assisted using recomputed Inertial Measurement Unit (IMU) error, suppress error divergence of an case solution non-availability. The IMU recomputation method firstly proposed, where GNSS/INS-derived position, velocity attitude (PVA)...
This paper is an introduction to software performance automated testing and theory. It introduces the features of Open Xml storage SQL Server storage. Then this sets three state scenes chooses different test tools respectively. Finally, it uses monitor index from these two data systems. Results are then analyzed, comparing quality systems same scene.
The developed CAPE (Computer Aided Process Engineering) application provides a helpful tool for performing the student laboratory works of chemical process control program study, allowing an efficient transfer from theoretic concepts to practical exemplification. Different pilot plants, such as: liquid accumulation in tank, heat jacketed reactor, gas set reservoirs or flow pipe-network, are fitted with specific instrumentation. By means special and built serial communication facility...
In this paper, we analyzed the impact of doing simple hands-on activities during physics lectures involving two introductory courses. Performance between students who were involved in activity was compared with those not. Both groups took same final exam questions from associated course. The problems common to all, only one group had opportunity test it out using low-tech experiments. terms background and major, student population used new tool as did It a mixture engineering majors....
