AOP (aspect oriented programming) is a programming paradigm for enhancing the degree of modularity in a system and it helps developers to maintain and manage the system easier. A bad smell means that a bad design that may lead to negative effects while developing a software system. Bad smells may also appear in the system that is developed using AOP paradigm. Therefore, it is important that bad smells...
Cloud computing is an emerging technique. Here comes many new development directions. Many researchers over the world show great interests in cloud architecture. Cloud-based video solutions are proposed to meet many technical challenges in the real world. However, the data security is a vital problem, especially about video data. This paper proposed an architecture to mine the huge amount 3D video...
Attribute dependency function is very important for feature selection in data mining, pattern recognition and machine learning. However, Pawlak's is inadequate for some information systems, and Daisuke's definition is only for categorical attribute. In this paper, we introduce a new definition based on partition for numerical attribute. The advantage of the definition is that heterogeneous features...
Shielding effectiveness (SE) of small enclosures within reverberation chamber is an important topic in EMC society in recent years. Since the field propagation within a reverberation chamber is randomly polarized and isotropic, it is useful to investigate the effect of polarization and incident angle of plane wave on the field distribution within a enclosure with aperture. The effects of polarization...
This study examines the relationship between positive affectivity, negative affectivity, job satisfaction, and life satisfaction using a sample of 558 urban employees from Dalian. Positive and negative affectivity were measured with Watson's PANAS scale, job satisfaction was measured with Spector's JSS scale, and life satisfaction was measured with the International Wellbeing Group's PWI scale. All...
This study examines the relationship between job satisfaction, positive affectivity, negative affectivity, distributive justice, and work group cohesion in China. All the survey instruments used in this study are well established multi-item scales that have been validated in English speaking populations. The statistical analysis shows that distributive justice, work group cohesion and positive affectivity...
For various applications, there is a growing need to determine the shielding effectiveness (SE) of physically small (but electrically large) enclosures or cavities. In this paper, a new measurement technique for SE of small enclosures is presented. This new technique is based on the statistical methods and multi-points measurement. The work is intended to provide further refinement in the consideration...
In the period of the water resources evolutionary investigation of North China, from the 3-D map composed of TM and DEM, the downstream of the Xilamulun river is the wide Kailu basin, with huge alluvial-lacustrine sandy sediments which constitute great Xiliaohe plain, but the watershed area has not sufficient water and sand-soil sediments enough to form such present huge sedimentary plain in theory...
A robust digital watermark scheme using wavelet-based is presented for copyright protecting. For security, the watermarking is perturbed firstly. A mark sequence may be gotten. For embed watermark imperceptibility, wavelet decomposition for original image is realized. After the original image decomposed into single resolution level, we connect three detail wavelet coefficient matrixes into a big matrix...
Besides effectively reducing the voltage stress of switches, the cascaded multilevel inverter could also improve the quality of output waveforms by addition of waveforms. The step waveform addition is a usual method. The addition could reduce the loss of switches, but the introduced angle of flow calculating methods of cascade inverters based on step waveform addition are only suitable for cascaded...
In this note, the limitations of conventional or separate gain or phase margin are shown. Then, the combined gain and phase margins are introduced to overcome the limitations and suit both stable and unstable systems. A simple method for their computations is presented and its application in stabilization is demonstrated.
3D-TV is well expected as next advancement in television. The conversion technique of two-dimensional (2D) images to 3D images is an effective way to alleviate the shortage of 3D contents. The most important and difficult problem in 2D-to-3D conversion is how to generate or estimate depth information using only a single-view image. In this paper, a new approach to estimate depth map from monocular...
Unsupervised or supervised anomaly intrusion detection techniques have great utility with the context of network intrusion detection system. However, large amount of labeled attack instances used by supervised approaches are difficult to obtain. And this makes most existing supervised techniques hardly be implemented in the real world. Unsupervised methods are superior in their independency on prior...
