Description: 计算机辅助正弦交流电路分析的理论及实现过程。分析方法采用节点分析法。采用了把一个二端元件定义一支路的概念，这种处理方法在网络分析中具有简单、易于掌握的特点。而在解线性方程时采用大家所熟悉的高斯—约当消去法。在建立方程的过程中采用的是形成Gn，Jn的直接填写法。为使读者理解编写通用程序的思路和方法，使用了大量的流程图。程序能处理含有导纳支路、电流源支路、电压源支路、四种受控源支路及含有互感支路的正弦稳态电路。-sinusoidal AC circuit computer-aided analysis of the theory and implementation process. Analysis using nodal analysis method. Used to bring a two-path components of a definition of the concept of this approach in network analysis is simple, easy-to-understand characteristics. The solution of linear equations used are all familiar with the Gauss-Jordan elimination method. The establishment of the equation used in the process of forming Gn, Jn fill in the direct method. In order to enable readers to understand the procedures for the preparation of general ideas and methods, the use of a large number of flow chart.

Description: 关于simu1:
在simlink运行之前的初始化过程中，完成了信道时延和幅度的估计，多径合成权系数估计
多径合成采用可选EG/MR/MMSE合成
信道可选白噪声信道AWGN和IEEE80.215.3a UWB标准信道模型(CM1-CM4)但为了简化，
这里采用了IEEE80.215.3a给出了信道模型中的仿真数据包(如果你是作超宽带的，信道模型程序和数据可从IEEE80.215.3a网站获取)
和大部分仿真一样，模型中的Eb/No指的是单比特信息符号携带的能量和噪声的比例，监督的讲，在AWGN信道中，Eb/No为4.31db时,误码率0.01
关于zslsimu直接运行simuuwb.m可看到结果)
显然和simu1一样，只是增加了.m文件，修改.m文件中的重要参数:多径数、PN序列长度、PN序列、单个信息码元宽度Tb(单位ns)、每个脉冲宽度Tc(单位ns)、系统的仿真精度Ts(单位ns)、仿真时间
chanidx=1:1是因为考虑信道数据文件太大，不好上传，想得到精确的仿真，同一个信道类型(chantype)，最好仿真100次实现，信道文件可由UWB标准组织下载-on simu1 : simlink operation before the initialization process, completed the channel delay and the magnitude of the estimates, Multi-Path weights estimated Drive synthesis using the optional EG / MR / Synthesis MMSE Channel optional white noise channel AW GN and IEEE80.215.3a UWB channel model (CM1 - CM4) in order to simplify IEEE80.215.3a used here is a channel model for the simulation data packets (if you were for extra-wide belt, channel model and data from IEEE80.215.3a website access) and most simulation, Model of Eb / No refers to the single-bit symbols to carry the message of energy and noise ratio, supervision speaking, In AWGN channel, Eb / No for 4.31db, BER 0.01 zslsimu directly on the operation simuuwb.m can see the result) clearly and si mu1, only increased. m document change

Description: 书名：基本商业程序的建模
Essential Business Process Modeling (Paperback)
作者： Mike Havey
出版商：O Reilly 1 edition (August 18, 2005)
内容介绍：
Ten years ago, groupware bundled with email and calendar applications helped track the flow of work from person to person within an organization. Workflow in today s enterprise means more monitoring and orchestrating massive systems. A new technology called Business Process Management, or BPM, helps software architects and developers design, code, run, administer, and monitor complex network-based business processes.
BPM replaces those sketchy flowchart diagrams that business analysts draw on whiteboards with a precise model that uses standard graphical and XML representations, and an architecture that allows it converse with other services, systems, and users.

Description: If you have programming experience and a familiarity with C--the dominant language in embedded systems--Programming Embedded Systems, Second Edition is exactly what you need to get started with embedded software. This software is ubiquitous, hidden away inside our watches, DVD players, mobile phones, anti-lock brakes, and even a few toasters. The military uses embedded software to guide missiles, detect enemy aircraft, and pilot UAVs. Communication satellites, deep-space probes, and many medical instruments would have been nearly impossible to create without embedded software.
