有效援助议程下的中国对非教育援助

有效援助是当前国际发展援助的重议程之一,同时也为国际教育援助直接指明了方向。在"中非合作论坛"框架下,中国对非教育援助规模不断扩大,影响日益增强。因此,在有效援助议程下,审视我国对非教育援助的政策与实践,不断提升我国对非教育援助的有效性,这对于其可持续发展有着重的意义。

平等权与财产权的矛盾——试析杰斐逊用“追求幸福权”代替“财产权”的原因

托马斯.杰斐逊在《独立宣言》中用"追求幸福权"代替"财产权",其真正用意何在?笔者认为主要是为了化解其心中平等与财产所导致的不平等及平等与黑奴这一特殊财产之间的两组矛盾,为以后的改革埋下伏笔。     

Nearest neighbor search algorithm based on multiple background grids for fluid simulation

The core of smoothed particle hydrodynamics (SPH) is the nearest neighbor search subroutine. In this paper, a nearest neighbor search algorithm which is based on multiple background grids and support variable smooth length is introduced. Through tested on lid driven cavity flow, it is clear that this method can provide high accuracy. Analysis and experiments have been made on its parallelism, and the results show that this method has better parallelism and with adding processors its accuracy become higher, thus it achieves that efficiency grows in pace with accuracy.     

Extraction of novel features for emotion recognition

Hilbert-Huang transform method has been widely utilized from its inception because of the superiority in varieties of areas. The Hilbert spectrum thus obtained is able to reflect the distribution of the signal energy in a number of scales accurately. In this paper, a novel feature called ECC is proposed via feature extraction of the Hilbert energy spectrum which describes the distribution of the instantaneous energy. The experimental results conspicuously demonstrate that ECC outperforms the traditional short-term average energy. Combination of the ECC with mel frequency cepstral coefficients (MFCC) delineates the distribution of energy in the time domain and frequency domain, and the features of this group achieve a better recognition effect compared with the feature combination of the short-term average energy, pitch and MFCC. Afterwards, further improvements of ECC are developed. TECC is gained by combining ECC with the teager energy operator, and EFCC is obtained by introducing the instantaneous frequency to the energy. In the experiments, seven status of emotion are selected to be recognized and the highest recognition rate 83.57% is achieved within the classification accuracy of boredom reaching 100%. The numerical results indicate that the proposed features ECC, TECC and EFCC can improve the performance of speech emotion recognition substantially.     

融贯中西的艺术孤行者——庄华岳与赵无极

庄华岳1935年考进国立艺术专科学校,与赵无极同班,感情甚笃,同是班里最为出类拔萃的.庄华岳在校学习时就显露出过人的天份和才能,成为老师眼中的奇才,作品受到业师吴大羽及同学赵无极的激赏.吴师拟荐庄出国留学,因抗战爆发终成泡影.后庄华岳几十年从事教育工作.赵无极毕业后赴法深造,成就为一代大师.1957年赵无极曾误信传言,...     

教学学术：高校教师专业发展的新维度
