Multi-band, multi-service and multi-modulation are new trends of GNSS development. Since novel modulation types like BOC/MBOC and multiplex techniques like (POCET, Interplex) of navigation signals have been utilized [1], the composite navigation performance is indeed improved. However, new challenges have arisen in the navigation signal quality monitoring area. Generally, common standard instruments,...
With the growth of the number of computer applications, all colleges and universities are bound to build their own computer rooms. There are many problems in previous room management means. This paper built a B/S structure-based IC card room management system utilizing the existing university campus network infrastructures and through network data transmission, which can uniformly manage all the rooms...
In this paper, a signal-processing approach is applied to enhance the inspection of wind turbine blades. This method starts with a time-frequency representation of signals, where a generalized time-bandwidth product method integrated with short-time Fourier transform is developed and applied. It is followed by the utilization of convex set to help justify the contour map such that the blade-condition...
