This paper presents a clustering approach
which estimates the specific subspace and the intrinsic dimension of each class. Our approach
adapts the Gaussian mixture model framework to high-dimensional data and estimates
the parameters which best fit the data. We obtain a robust clustering method called High-
Dimensional Data Clustering (HDDC). We apply HDDC to locate objects in natural images
in a probabilistic framework. Experiments on a recently proposed database demonstrate the
effectiveness of our clustering method for category localization.

Study-of-VSC-HVDC-Controller-
风电潮流的波动会引起并网系统公共连接点（PCC）电压的波动。在基于电压源换流
器的高压直流输电（VSC-HVDC）交直流混合风电场并网系统中，控制VSC-HVDC 送端站注入
到PCC 点的无功功率可以抑制电压波动。本文讨论了VSC-HVDC 的无功功率控制器和定电压控制
器抑制电压波动的原理。基于电磁暂态软件PSCAD/EMTDC 建立了并网风电场模型、VSC-HVDC
模型及控制系统模型。仿真结果表明VSC-HVDC 采用定电压控制器的并网系统能更好的抑制电
压波动，采用无功功率控制器的系统具有较好的风电场并网性能。(Reactive power variation of integration wind farm may cause point of common
coupling （PCC） voltage fluctuation. In hybrid wind farm integration system based on HVDC of
voltage source converter （VSC-HVDC）, the voltage fluctuation can be alleviated by compensating
reactive power to PCC from VSC-HVDC sending end. Therefore, the reactive power controller and the
stable voltage controller to alleviate voltage fluctuation are studied in the paper. The integration wind
farm, VSC-HVDC and their controller models are set up by PSCAD/EMTDC. The simulation results
show that the integration system adopted stable voltage controller has a better performance to alleviate
voltage fluctuation. However the system adopted reactive controller has a good wind farm integration
capability.)

中文摘要
正交频分复用（ OFDM ， Orthogonal Frequency Division
Multiplexing）是当前一种非常热门的通信技术。它即可以被看作是一种
调制技术，也可以被看作是一种复用技术。由于它具有抗多径衰落和频谱
利用率高的特点，因此被广泛应用于高速数字通信领域，比如应用于IEEE
802.11a无线局域网（WLAN）的物理层等等。
我的毕业设计的核心任务是：采用 FPGA 来实现一个基于OFDM 技术
的通信系统中的基带数据处理部分，即调制解调器。其中发射部分的调制
器包括：信道编码（Reed-Solomon 编码），交织，星座映射，FFT和插
入循环前缀等模块。我另外制作了相应的解调器，可以实现上述功能的逆
变换。
另外，我还对OFDM技术， IEEE 802.11a的标准文献，基于Simulink
的 OFDM 模型和仿真，ALTERA 公司的技术和 IP Core 的使用等方面进
行了研究。这些在文章中都有体现。

Orthogonal frequency division multiplexing (OFDM, Orthogonal the Frequency Division,
Multiplexing) is a very popular communication technology. It can be seen as a
Modulation technique can also be seen as a multiplexing technique. Because of its resistance to multipath fading and spectrum
High utilization characteristics, and is widely used in high-speed digital communications, such as used in IEEE
802.11a wireless LAN (WLAN) physical layer.
The core mission of my graduation project: FPGA to implement a technology based on OFDM
Communication systems in baseband data processing part, ie the modem. These emission part of the modulation
Includes: channel coding (Reed-Solomon coding), interleaving, constellation mapping, FFT and interpolation
Into the cyclic prefix modules. I also produced a corresponding demodulator can achieve the inverse of the above functions

Locally-Laplace-Isometries
发表在 The MIT Talbot 2013 Workshop 的论文 (Locally Laplace Isometries and Fibonacci Primes. this paper shows that there exists a reversible, unique and separable elliptic, Brahmagupta arrow. In this setting, the ability to study positive scalars is essential. Recent interest in partially ultra-positive domains has centered on deriving Pythagoras{Wiles scalars.)
