＜正＞This paper describes a Japanese-to-Chinese spoken language translation （SLT） method based on simple expression and presents the experimental results. The method is aimed at developing a compact speech translation system, which is robust for spontaneous spoken language phenomena, inc.uding the recognition errors and different expression from various speakers, The idea of translation method based on simple expression is that the mechanism interprets speech-act rather than the direct translation of the speaker’s words. The method is realized by mapping the simple expression instead of deep parsing. In this method, only keywords in speech recognition results are extracted, and the corresponding target sentences are extracted from the database by selecting similar example sentences with the keywords. All training sentences in the bilingual corpus are rewritten into the simple expression and grouped by rules. The rules are specially designed to develop the compact size example database for translation. Comparing with other example-based approaches to SLT, the method based on simple expression is easy to realize, and especially it is practical to develop the SLT systems limited in specific domains.

根据光伏发电系统的历史发电数据和气象数据,考虑天气类型、日照强度和大气温度及风速等因素,提出一种基于非负矩阵分解(nonnegative matrix factorization,NMF)和支持向量机(support vector machine,SVM)的光伏系统发电功率短期预测模型。基于差异性和相关性原理,同时考虑相似日选择算法,通过NMF算法对由相似日组成的输入样本进行分解,得到非负的低维映射矩阵,将其作为支持向量机的输入,预测光伏系统的发电功率。该模型在消除冗余信息、减少变量维数的同时,保留了原始问题的实际意义。实例表明,该方法降维效果明显,预测精度得到显著的提高。

A reduced surface electric field in an AlGaN/GaN high electron mobility transistor （HEMT） is investigated by employing a localized Mg-doped layer under the two-dimensional electron gas （2-DEG） channel as an electric field shaping layer. The electric field strength around the gate edge is effectively relieved and the surface electric field is distributed evenly as compared with those of HEMTs with conventional source-connected field plate and double field plate structures with the same device physical dimensions. Compared with the HEMTs with conventional sourceconnected field plates and double field plates, the HEMT with a Mg-doped layer also shows that the breakdown location shifts from the surface of the gate edge to the bulk Mg-doped layer edge. By optimizing both the length of Mg-doped layer, Lm, and the doping concentration, a 5.5 times and 3 times the reduction in the peak electric field near the drain side gate edge is observed as compared with those of the HEMTs with source-connected field plate structure and double field plate structure, respectively. In a device with VGS = -5 V, Lm 1.5 m, a peak Mg doping concentration of 8×10^17 cm-3 and a drift region length of 10 m, the breakdown voltage is observed to inc.ease from 560 V in a conventional device without field plate structure to over 900 V without any area overhead penalty.

＜正＞This paper proposes a syllabie context dependent model for spontaneous speech recognition. It is generally assumed that, sinc. spontaneous speech is greatly affected by coarticulation, an acoustic model featuring a longer range phonemic context is required to achieve a high degree of recognition accuracy. This motivated the authors to investigate a tri-syllable model that takes differences in the preceding and succeeding syllables into account. Sinc. Japanese syllables consist of either a single vowel or a consonam and vowel combination, a tri-syllable model always rakes the preceding and succeeding vowels that are the primarv factors in coarticulation into account. A tri-svllable model is thus capable of efficientry representing coarticulation. The tri-syllable model was trained using spontaneous speech;then, the effectiveness of continuous syllable recognition and statistical language model-based continuous word recognition were evaluated. Compared to a regular triphone model without state sharing, it was found that the correct syllable accuracy of the continuous syllable recognition improved fronl 64.9% to 66.3%. The word recognition accuracy for the statistieal language modelbased continuous word recognition improved from 88.4% to 89.2%.
