Background Evidence shows that research abstracts are commonly inconsistent with their corresponding full reports, and may mislead readers. In this scoping review, which is part of our series on the state of reporting of primary biomedical research, we summarized the evidence from systematic reviews and surveys, to investigate the current state of inconsistent abstract reporting, and to evaluate factors...
This paper focuses on a RFID-Based dynamic positioning scheme, aiming to locate an object by using a moving RFID reader and reference tags without recording any measurement data, e.g., the time of arrival (TOA) of the signal, or the received signal strength indication (RSSI). To address the problem of blindness of location path, a RFID-based positioning scheme with MATLAB GUI, is proposed based on...
To improve the hand gesture recognition accuracy based on Hu moment features, a new recognition algorithm was developed based on the fingertip structure detection. Firstly, the geometric features, the areas of skin region and the image, were designed to segment the skin region from the background in space of hue, saturation and value of brightness. Secondly, the cam point inspections were carried...
In this paper factors affecting accuracy of time synchronization in EPON are analysed and the scheme of time synchronization in EPON based on IEEE1588v2 protocol is designed and implemented by FPGA. Experimental result shows that the scheme is feasible and good time synchronization accuracy about 20 nanoseconds can be reached.
The vehicle license plate (VLP) location is the key technique of the vehicle license plate recognition system. The region of license plate has rich edge information and fixed color feature. The location method fusing gray edge and color feature is more accurate and easier than the method only in gray space or in color space. The experiments on 200 Chinese automobile RGB real color images taken from...
Affected by the measurement errors of sensors and vibration interferences of railways, there are computational errors accumulating with time for inertial measurement system of tilting train based on math platform. Combined the inertial algorithm with the measured data, methods of dynamic errors compensation based on Kalman filter are researched. Based on the error mathematical models, corresponding...
To build laboratories better, it is necessary to evaluate them reasonably. In this paper, we classed laboratories into three grades, construct evaluation model based on Levenberg-Marquardt neural network arithmetic, and using this model to evaluate laboratories of some universities belong to national ministry of education. The result shows it is well and suitable grade evaluation for university laboratories.
