Reliable automatic ship detection in Synthetic Aperture Radar (SAR) imagery plays an important role in the surveillance of maritime activity. Apart from the well-known Spectral Residual (SR) and CFAR detector, there has emerged a novel method for SAR ship detection, based on the deep learning features. Within this paper, we present a framework of Sea-Land Segmentation-based Convolutional Neural Network...
With the developing of computer network technology, the popularizing of computer in college and the increasing demand of continuing education in society, The modern distance education which based on net become the main trend and direction of high educational reform. Based on modern distance education fast information dissemination ability, excellent resources sharing, the advanced performance two-way...
The national Separate Enrollment in physical education is an independent examination set by the state general sport administration including tests of Extracurricular courses and tests of specialty. Test of Basketball, one of the special tests, consists of 60-metre running, approach run and touch basket board, and shooting in limited time, dribble and shoot from diverse directions, and actual competition...
For the flexibility and efficiency of the commercial operation of the Maglev transportation, the Maglev train system should have the property of interoperability. The basic system requirements for the interoperability were introduced and the corresponding control system was designed. The operation procedure of the Maglev between different lines equipped with control systems for the interoperability...
In the data grid environment, when users access to files, how to select the best site to obtain files from multiple replicas and reach the highest QOS (quality of service) in the cost of same price is a problem that need to be studied urgently, that is replica selection. In this paper, it proposes a new combination algorithm based on genetic algorithm and ant algorithm, which not only solves the inefficient...
In order to solve the contradiction between lightweight and noise of a vibrating cantilever beam, active control actuated by piezoelectric ceramics is presented in this study. The dynamic model of the cantilever beam is established by finite element method (FEM). The piezoelectric actuator excited by control signal is bonded near the fixed end of the cantilever beam to suppress the beam's first vibration...
One design method of 32 bits comparator for multi-number systems was proposed. In this method, 64 bits double precision floating point data and 32 bits single precision floating point data based on IEEE754 standard, 32 bits signed fixed point data and 32 bits unsigned fixed point data can be processed by the same comparator. An RTL module was implemented based on the proposed method. This RTL module...
