Dielectric response(DR) measurement has been deployed as a non-destructive and potential diagnostic method for moisture or aging condition of power system apparatuses. In order to promote the application of DR method, development of precise, easy-to-use and cost-effective testing devices is an urgent issue, in which accurate acquisition of the insulation current is critical. In this paper, a DR testing...
Audio semantic analysis is an important issue for multimedia applications. In this paper, we propose a neural network based approach to analyze the high-level semantic content of audio event sequences for the action movies. According to the time interval between adjacent basic audio events, we first divide the given event sequence into some scene segments, and then discover the high-level semantic...
This paper presents conversion to circular or tilted linear polarization by adding a layer of apertures over the plate-laminated-waveguide corporate-feed slot array antenna. A circularly polarized 16×16-element array antenna achieves high antenna efficiency of 91.6% including losses at 61.5GHz by diffusion bonding of laminated metal thin plates. In a tilted linearly polarized 16×16-element array antenna,...
In order to achieve a wide bandwidth characteristic of high gain, high efficiency and low side lobe level, a plate-laminated-waveguide corporate-feed 45-degree linearly-polarized aperture array antenna is proposed. A 4-element sub-array is designed for a 256-element array. The 256-element array is fabricated by diffusion bonding of etched thin copper plates in the 60 GHz-band. About 70 % antenna efficiency...
As the scale and complexity of software systems increasing, researches have begun to place much more emphasis on the area of software measurement, especially coupling measurement in object-oriented systems. In order to understand the coupling measure, we make use of complex network theory to characterize and describe its macroscopic properties. A novel software coupling network was proposed firstly,...
