We propose in this paper a deep learning model based on convolutional neural network (CNN) for biopsy image grading. The model outputs a vector of scores indicating presence or severity of the target histopathological characteristics. Within the model, we first design a 7-layer CNN for feature representation and high level concept extraction. Each biopsy image is expressed as a feature vector through...
The International Reference Ionosphere model (IRI) is generally accepted standard ionosphere model. It describes the ionosphere environment in quiet state and predicts the ionosphere parameters within a certain precision. In this paper, we've made a breakthrough in modifying the IRI model for Chinese region. Construct the ionosphere parameters foF2 and M(3000)F2 by using the CRI (Chinese Reference...

Isolation between antennas is one of the most important indexes for electromagnetic compatibility (EMC) problem on airborne platform. Take the Rooivalk helicopter for example, as the electrically size of the airborne platform is large, the structure is complex, the simulation results are usually not accurate enough. Due to the inaccuracy of the former modeling method which used the simple typical...
In the generating system of electromagnetic mesh, the most crucial technique is to generate the effective and exact mesh. With the AutoCAD as the graphics support platform, this thesis develops software of auto dissection with three-dimensional mesh for the finite-difference time-domain electromagnetic simulation, applying ObjectARX of AutoCAD, combined with the graphic file of AutoCAD. The method...
