The multiple instance regression problem has become a hot research topic recently. There are several approaches to the multiple instance regression problem, such as Salience, Citation KNN, and MI-ClusterRegress. All of these solutions work in batch mode during the training step. However, in practice, examples usually arrive in sequence. Therefore, the training step cannot be accomplished once. In this paper, an online multiple instance regression method ＂OnlineMIR＂ is proposed. OnlineMIR can not only predict the label of a new bag, but also update the current regression model with the latest arrived bag. The experimental results show that OnlineMIR achieves good performances on both synthetic and real data sets.

The System of Face Detection Based on OpenCV

第24届中国控制与决策会议

作者： Xianghua Fan, Fuyou Zhang, Haixia Wang, Xiao Lu Key Laboratory for Robot & Intelligent Technology of Shandong Province, Shandong University of Science and Technology, qingdao 266590

Face detection technology has widely attracted attention due to its enormous application value and market potential, such as face recognition and video surveillance system. Real-time face detection not only is one part of the automatic face recognition system but also is developing an independent research subject. So, there are many approaches to solve face detection. Here the modified AdaBoost algorithm based on OpenCV is presented, and experiments of real-time face detecting are also given through two methods of timer and dual-thread. The result shows that the method of face detection with dual-thread is simpler, smoother and more precise.

社会的全面进步与人的全面发展是互为前提的。时代发展需要的科技人才不仅要有较强的专业功底,而且要具备良好的人文素养,这也是我国当下和谐社会构建的迫切要求、大学生自身全面发展的主体诉求。当前理工科大学生人文素质普遍偏低,其成因主要有传统教育观念与社会环境的影响、教师自身人文素质偏低、大学生自身提高人文素质的意识不够等。应积极寻求人文关怀,促进大学生素质的和谐发展。

Earthquake Engineering and Engineering Vibration 2012年第4期11卷 445-460页

作者： Zhang Ning Gao Yufeng Li Dayong Wu Yongxin Zhang Fei Geotechnical Research Institute Hohai University Key Laboratory of Geomechanics and Embankment Engineering(Hohai University) Ministry of Education College of Civil Engineering&Architecture Shandong University of Science and Technology

This paper reports a series solution of wave functions for two-dimensional scattering and diffraction of plane SH waves induced by a symmetrical V-shaped canyon with different shape ratios. A half-space with a symmetrical V-shaped canyon is divided into two sub-regions by using a circular-arc auxiliary boundary. The two sub-regions are represented by global and local cylindrical coordinate systems, respectively. In each coordinate system, the wave field satisfying the Helmholtz equation is represented by the separation of variables method, in terms of the series of both Bessel functions and Hankel functions with unknown complex coefficients. Then, the two wave fields are described in the local coordinate system using the Graf addition theorem. Finally, the unknown coefficients are sought by satisfying the continuity conditions of the auxiliary boundary. To consider the phase characteristics of the wave scattering, a parametric analysis is carried out in the time domain by assuming an incident signal of the Ricker type. Surface and subsurface transient responses demonstrate the characteristics and mechanisms of wave propagating and scattering.

The Analysis of Night-time VTEC Average Value

第三届中国卫星导航学术年会

作者： ZHOU Weili 1,2 SONG Shuli 2 ZHENG Zuoya 1 ZHU Wenyao 2 (1 Geomatics College, Shandong University of Science and Technology, qingdao 266590) (2 Shanghai Astronomical Observatory, Chinese Academy of Sciences, Shanghai 200030)

Ionospheric delay is an important error source in satellite navigation and positioning, which can be weakened by Klobuchar, a widely used and practical model. The night-time VTEC (Vertical Total Electron Content) is an important characteristic parameter of Klobuchar model, the changes of night-time VTEC affect in calculation precision of the Klobuchar model directly. In this paper, with the global ionosphere VTEC (1998-2010) produced by IGS, The rationality and reliability of night-time VTEC average value sets are estimated. The suitable time of night-time VTEC observations are analyzed according to different accuracy needs. The night-time VTEC average values are analyzed quantitatively and studied, in detail, in terms of the alteration of latitude、seasons and solar activity. The results show that night-time VTEC suitable time is 20:00LT-06:00LT, while VTEC changes at night is greater before midnight, more stable after midnight. The night-time VTEC value has obvious seasonal variation, peak values appearing in spring and autumn, minimum value in summer. In peak years of solar activity, the average of night-time VTEC gets up to 25-30TECU in spring and autumn, 20TECU in winter, 15TECU in summer, having a great value in Klobuchar deviation. The changes of night-time VTEC average value with latitude is very apparent in the peak period, having the mean value from 30TECU in low latitude region down to 15 TECU in high latitude region, which is very small in valley years of solar activity, the difference with 1-2TECU. In southern hemisphere winter, the night-time VTEC average value shows regional variation. There is a high value in India Ocean south, low value in southern pacific. The difference in those two regions is more than 15TECU in peak years, and up to 10TECU in valley years.
