Objective
Dynamic monitoring of the concentration variation of IgM and IgG in patients with SARS‐CoV‐2 infections and exploring their diagnostic value for coronavirus disease‐19 (COVID‐19).
Methods
A total of 15 patients with SARS‐CoV‐2 infection were enrolled as the COVID‐19 group, and 50 patients were enrolled as the control group. The concentrations of SARS‐CoV‐2‐specific antibodies (IgM and...
A 0.35um HVCMOS Triple Level array drive ASIC protype has been designed and fabricated for the Smectic-A liquid crystal Electric paper displayer (EPD). The pulse switch matrix for the low-to-high voltage level shifter is employed not only for saving the die size and power supply but also for better controlling the output high voltage level edges. Together with the symmetry positive and negative high...
A latitude method for the trajectory planning of spraying on spherical surface is presented. The latitude method is used to optimize the time and coating thickness in the spray painting. The start curve, the velocity of the spray gun and the width between neighboring paths are the main factors to affect the final coating quality. Spray painting time is determined by the start curve of the gun, while...
The error correction of MEMS Inertial Measurement Unit (IMU) is often implemented by the model filtering as well as the compensation of instrument error, which effectiveness of filtering is determined by the coherence between the models of filter and the maneuver modes of weapons. As the maneuverability of advanced rocket ammunitions with the lateral thrust greatly increased, the traditional filter...
Comparing with Simulated Annealing (SA) that is often used in the image segmentations based on Markov Random Field (MRF) models, Genetic Algorithm (GA) has been applied into reducing the computation complexity of optimization. However many scholars used GA as an optimal tool that based on the gray-scale values of pixels as individuals and limited the mutations and crossovers with the gray-level coding,...
Markov Random Field (MRF) has been found to be effective in the domains of image segmentations, since the problems can be simplified to search the optimal label fields. The challenges in MRF image segmentations arise due to the complexity of optimization. Although Genetic Algorithm (GA) has been applied into the image segmentation with MRF, yet most of algorithms defined an individual as a pixel with...
Rapid and high flexible of product manufacturing cell is requested in agile manufacturing. Compositive module and functional structure of the flexible punching and shearing die is designed for rebuilding traditional manufacturing devices and realizing the thought of rapid and flexible manufacturing. The method to design NC programmed technology of graphics processing model is illustrated in detail...
Both high performance and high reliability are necessary for the automatic fare collection system. The IC card ticket system, developed in order to improve the passengers' satisfaction and to reduce the maintenance costs, cannot avoid the requirements, either. However, this new system has a problem; high performance on wireless communications lowers reliability. The solutions are the "autonomous...
