中点箝位式三电平逆变器空间矢量调制
论述一种中点箝位式三电平逆变器SVPWM原理及其实现方法。为避免三电平逆变器在扇区切换中输出矢量突变，提出了一种首发矢量全部采用正小矢量或负小矢量的空间矢量调制算法，利用三个判断规则，可以很方便地确定出参考矢量所在的扇区和小三角形，给出了合成矢量的相应输出电压矢量，推导出三角形顶点工作矢量的作用时间。并提出一种充分利用冗余电压矢量的中点电压控制方法，实现了电容电压的平衡。实验研究结果证实本文提出的调制算法是正确且有效的。

verilog_IEEE官方标准手册-2005_IEEE_P1364
The Verilog® Hardware Description Language (Verilog HDL) became an IEEE standard in 1995 as IEEEStd 1364-1995. It was designed to be simple, intuitive, and effective at multiple levels of abstraction in astandard textual format for a variety of design tools, including verification simulation, timiThe clear directive from the users for these three task forces was to start by solving some of the followingproblemsConsolidate existing IeeE Std 1364-1995Verilog generate statementMulti-dimensional arraysEnhanced Verilog file i/oRe-entrant tasksStandardize Verilog configurationsEnhance timing representationEnhance the vpi routinesAchievementsOver a period of four years the 1364 Verilog Standards Group(vsg) has produced five drafts of the lrmThe three task forces went through the EEe Std 1364-1995 lRM very thoroughly and in the process of consolidating the existing Lrm have been able to provide nearly three hundred clarifications and errata for theBehavioral, ASIC, and PLI sections. In addition, the vsg has also been able to agree on all the enhance-ments that were requested (including the ones stated above)Three new sections have been added. Clause 13, "Configuring the contents of a design, deals with configuration management and has been added to facilitate both the sharing of verilog designs between designersand/or design groups and the repeatability of the exact contents of a given simulation session Clause 15Timing checks, "has been broken out of Clause 17, "System tasks and functions, "and details more fullhow timing checks are used in specify blocks. Clause 16, "Backannotation using the Standard Delay Format(SDF), addresses using back annotation(IEEE Std 1497-1999)within IEEE Std 1364-2001Extreme care has been taken to enhance the vpi routines to handle all the enhancements in the behavioraland other areas of the lrm. minimum work has been done on the pli routines and most of the work hasbeen concentrated on the vpi routines. Some of the enhancements in the vpi are the save and restart simu-lation control, work area access, error handling, assign/deassign and support for array of instances, generateand file 1/0Work on this standard would not have been possible without funding from the cas society of the ieee andOpen verilog InternationalThe IEEE Std 1364-2001 Verilog standards Group organizationMany individuals from many different organizations participated directly or indirectly in the standardizationprocess. The main body of the Ieee Std 1364-2001 working group is located in the United States, with asubgroup in Japan (EIAJ/1364HDL)The members of the IEEE Std 1364-2001 working group had voting privileges and all motions had to beapproved by this group to be implemented the three task forces focused on their specific areas and theirrecommendations were eventually voted on by the Ieee Std 1364-2001 working group

语音情感识别系统matlab仿真
过特定人语音情感数据库的建立；语音情感特征提取；语音情感分类器的设计，完成了一个特定人语音情感识别的初步系统。对于单个特定人，可以识别平静、悲伤、愤怒、惊讶、高兴5种情感，除愤怒和高兴之间混淆程度相对较大之外，各类之间区分特性良好，平均分类正确率为93.7%。对于三个特定人组成的特定人群，可以识别平静、愤怒、悲伤3种情感，各类之间区分特性良好，平均分类正确率为94.4%。其中分类器采用混合高斯分布模型。
