应用化学"113"人才培养体系的探索

In order to bridge the gap between the supply and the demand of talent cultivation, the existing talent cultivation system of applied chemistry specialty is reformed and a new "113" talent cultivation system is guided by Outcome-Based Education (OBE) education. The advanced engineering education mode is adopted to provide students with an engineering education based on the background environment of the conceptual-design-implementation-operation (CDIO) process. The characteristic "three modernizations" education mechanism, namely, cooperative education, family training and personalized guidance, are implemented. By building a new system of "113" talents training, an engineering talent training environment is formed, which takes the family as a unit, the enterprise as the background, and the project as the carrier. The problem of separating the supply from the demand of talents training for applied chemistry specialty will be fundamentally solved.     

一种基于信息复用的Boosting瀑布型分类器高效训练方法

构建一个基于Boosting的瀑布型分类器往往要花费巨大的计算代价,该文提出一种改进的Boosting瀑布型分类器训练算法,利用不同层级分类器之间的共享信息复用来提高训练速度。该文提出的瀑布型分类器训练方法在两个层次上复用已获得的层级分类器中的信息。在分类器层次上,前一个层级分类器在新的层级分类器训练过程中成为第1个特征,并在当前层级分类器的训练样本集上进行适应性学习;在特征层次上,每一级分类器都直接保留所有前面层级分类器已经学到的特征,并重新在当前层级分类器的训练样本集上进行适应性学习。最后,再通过学习新的弱分类器,加入新特征。在正面人脸检测问题上的实验表明,提出的新算法相比传统方法能够大幅提高Boosting瀑布型分类器的训练速度,提高幅度近10倍,瀑布型分类器的训练时间从将近3天降到了8个小时。

Effects of Professional Singing Education on Vocal Vibrato—A Longitudinal Study

Vocal vibrato is regarded as one of the essential characteristics of voice quality in classical singing. Professional singers seem to develop vibrato automatically, without actively striving to acquire it. In this longitudinal investigation, the vocal vibrato of 22 singing students was examined at the beginning of and after 3 years of professional singing education. Subjects sang an ascending-descending triad pattern in slow tempo on vowel [a:] at a comfortable pitch level twice at soft (piano) and twice at medium (mezzoforte) loudness. The top note of the triad pattern was sustained for approximately 5s. The mean and the standard deviation (SD) of the vibrato rate were measured for this note. Results revealed that after 3 years of training, voices with vibrato slower than 5.2 Hz were found to have a faster vibrato, and voices with vibrato faster than 5.8 Hz were found to have a slower vibrato. Standard deviation of vibrato rate was higher in soft than in medium loudness, particularly before the education. Also high values of SD of vibrato rate, exceeding 0.65 Hz, had decreased after the education. These findings confirm that vibrato characteristics can be affected by singing education.     

一种改进的基于训练序列的OFDM符号同步算法

同步问题是正交频分复用应用中的关键技术。研究了基于训练序列的schmidl＆Cox（sc）算法，针对SC算法误差大的缺点，通过增加计算点数和平滑最大值处理方法来进行算法改进。通过MATLAB进行仿真分析，改进的算法虽然计算量有所增加，但有效减少符号定时的波动，在低信噪比情况下定时同步性能有明显改善。
