Cloud network system will meet the military demand on sea battlefield more effectively. Taking cloud computing as the core, the conception of sea battlefield cloud network has been presented. Combat cloud from it can strengthen the capability of collaborative combat in sea battlefield. Then, infrastructure of sea battlefield cloud network is constructed according to the tactics needs on sea battlefield...
In this paper, we propose a novel method for point clouds registration. In point clouds, there always exist a large number of surfaces with low curvatures. Let the surface locate in an OXYZ coordinate system, if we rotate the mean normal of the surface parallel with the Z axis, the 3D surface can be projected to 2D image via orthographic projection. Then we can detect and describe SIFT features in...
Synthetic lethality (SL) is a novel strategy for anticancer therapies, whereby mutations of two genes will kill a cell but mutation of a single gene will not. Therefore, a cancer-specific mutation combined with a drug-induced mutation, if they have SL interactions, will selectively kill cancer cells. While numerous SL interactions have been identified in yeast, only a few have been known in human...
Inspired by the key concept of participation in interaction theory, an empirical study was conducted to investigate learning participation through various channels, especially mutimedias, such as: online platform, MLS (Multimedia Learning System) and QQ, etc., and factors affecting participation. The subjects of study were from Hebei Open Edaucation Institution. Data were collected from questionnaire...
The definitions of intuitionistic fuzzy rough sets can usually be divided into two kinds. According to one kind, each intuitionistic fuzzy rough set is constructed by a couple of intuitionistic fuzzy sets. According to the other, each intuitionistic fuzzy rough set is constructed by a couple of fuzzy rough sets. In this paper, another kind definition is proposed that each intuitionistic fuzzy rough...
This paper presents a method of fault polygon extraction and smoothing. It uses boundary tracking algorithm to extract breakpoint locations to form polygon file, and uses parameters of angles between fault polygonal lines as well as edge length and so on to do the work of smoothing, on condition that it keeps its original shape. This method improves the visual effect and aesthetic extent and offers...
After the studying of the key technologies about web mining technology and modeling user profile, the paper did hard in two aspects: clustering based on content, creating the user interest model. The personalized user model was proposed, which oriented single user, combined the user's manual modeling and system automatic modeling; the Web page personalized recommendation and update algorithm of the...
Key management poses a main concern for security operation in wireless sensor networks. Most existing key management schemes try to establish shared keys for all pairs of neighbor sensors in homogeneous sensor networks. In recent, some research has demonstrated that heterogeneous sensor networks can achieve better performance in security than homogeneous networks. In this paper we propose a key- chain...
This paper designed a wall-climbing robot for painting the hull surface. The robot walked with caterpillar, permanent adsorption and driven by AC servo motor, the paint system was controlled by solenoid valve and pressure pump. Control system uses the supervisory computer and lower computer of two-stage distributional control mode. And the robot itself is equipped with a visual system to observe the...
The purpose of this study was to compare data collected via online surveys to via paper-and-pencil ones in mental health fields. Two groups of participants completed the Adult Adaptation Inventory (AAI) and Self-rating depression scale (SDS) either in online format or in paper-and-pencil format independently. Data collected via paper-and-pencil surveys had more missing data than Internet-based ones...
Essence of software testing is to choose a representative value (known as test case) from the input to perform the programs under test. The actual results of the programs will be checked to verify the consistency with the expected ones. If the results are different, it should take some correction and adjustment correspondingly. The existing method for test suite generation is mainly based on the test...
