C开发人员，初级面试100道题，可以多看看，有利于打开开发的门。(C developers, primary interview 100 questions, you can see more, to open the doors of development.)

说明：  贝叶斯与决策树想结合的方法研究论文小合集(Bayesian and decision tree method of combining research paper to a small Collection)

《Python核心编程》。著名的自由软件作者Eric Raymond建议人们从Python开始学习编程。这的确是一个中肯的建议，对于那些从来没有学习过编程或者并非计算机专业的编程学习者而言，Python是最好的选择之一。(Python is an object-oriented explanation of computer programming languages, is a powerful and well-size-fits-all language, has been more than a decade of development, maturity and stability. Python scripting language with the most rich and powerful class library, enough to support the vast majority of day-to-day applications. )

本文对16QAM解调软信息输出(LLR)理论计算方法进行分析，推导 出其简化解调算法。将两者在性能和计算复杂度方面进行了分析比较，并分别在 高斯白噪声信道和瑞利衰落信道环境下进行仿真(In this paper, 16QAM demodulator soft information output (LLR) theoretical calculation method for the analysis derived simplified demodulation algorithm. Both in performance and computational complexity aspects are analyzed and compared, and in white Gaussian noise channel and Rayleigh fading channel simulation environment)

该文档为达芬奇技术概述，相信对新入门的人会有帮助(The document believe that the new entry would be helpful for DaVinci Technology Overview)

系统介绍用mongdb编写python的注意事项及实例，以及mongdb编写的网络框架！(System Introduction written mongdb python precautions and examples, as well as networking framework mongdb prepared!)

美国Richard O.Duda编著的pattern classification，是学习模式识别的好书，里面含有中英文两个版本，希望对大家学习有帮助！(The United States, Richard O.Duda compiled pattern classification, learning pattern recognition book, which contains two versions of Chinese and English learning!)

初始对准技术是惯性导航系统的关键技术之一，初始对准的快速性和精度直 接关系到捷联惯导系统的性能。论文以罗经对准方法在捷联惯导系统中的应用为 目的，深入地进行了理论、实验和应用研究。 理论上，由捷联式惯导系统误差模型开始，结合罗经对准原理，建立罗经对 准数学模型。在此基础上，设计算法和控制流程，并依据控制理论选择适当的控 制参数。 在理论分析之后，针对可能出现的多种外界条件进行模拟数据仿真实验验证 算法和参数选择的正确性。仿真实验结果表明:在SOOs内系统对准精度达到0.10 并目_适用十高纬度地区。 车载试验数据离线分析，试验中使用GPS测得的速度信息作为外测参考速 度信息，在车辆运动过程中对准系统保持工作状态。将导航解算得到的结果与 GPS测得的信息进行比较分析，导航精度与GPS精度相当，即速度精度0.2m/s 水平位置精度lOmo (StudyongyrocompassAlignmentforSINS)
