    The Art of Assembly Language Amazing! You’re actually reading this. That puts you into one of three categories: a student who is being forced to read this stuff for a class, someone who picked up this book by accident (probably because you have yet to be indoctrinated by the world at large), or one of the few who actually have an interest in learning assembly language.

    There are many algorithms that can be applied to graphs. Many of these are actually used in the real world, such as Dijkstra’s algorithm to find shortest paths. We will discuss a few here.

    data are often used interchangeably, they are actually very different. Data is a set of unrelated information, and as such is of no use until it is properly evaluated. Upon evaluation, once there is some significant relation between data, and they show some relevance, then they are converted into information. Now this same data can be used for different purposes. Thus, till the data convey some information, t

  • 单片机控制的铅酸蓄电池充电电源

     为了有效地提升铅酸蓄电池的使用寿命,同时实现对充电过程的监控,设计出一种用单片机控制的36 V铅酸蓄电池充电电源。本电路采用反激式拓扑,连续电流工作模式,电源管理IC设计在电源的副边,由ELAN公司的EM78P258N单片机模拟,是用可编程器件模拟电源管理IC,实现智能电源低成本化的一次成功尝试,通过对单片机的软件设计实现了充电电源的状态显示、充电时间控制、报警、过温保护、过压保护、过流保护等功能。本充电器真正的实现了铅酸蓄电池的三段式充电过程,其最高输出功率可达90 W,效率约85%,成本不到20元,具有很高的市场竞争力。 Abstract:  In order to extend the life of lead-acid battery efficiently and supervise the charging process meanwhile, a 36V lead-acid battery charge powe supply controlled by microcontroller is designed. The charger is flyback switching power supply and works in CCM mode. A EM78P258N microcontroller made by ELAN microelectronics corporation is used as power management IC which is designed at the secondary circuit. The project is a successful attempt to low-cost intelligent power used microcontroller simulating power management IC. The charger also has the functions of the status reveal, charge time control, alarming, thermal protect, current limit and overvoltage protect by the software design. The circuit actually implements the three-step charge process, whose power is up to 90W and whose efficiency can get 85%. The net cost of this charger is less than 20 RMB, so that the charger is of powerful market competitiveness.

  • This simple SDI Notepad-like application demonstrates how, taking advantage of the MFC support for U

    This simple SDI Notepad-like application demonstrates how, taking advantage of the MFC support for Unicode, to Turkmenize labels of the specified menu items. actually, Turkmen is not supported by Windows 2000, therefore, to create such resources as menu so that strings in Turkmen could be displayed I had to invent an additional technique 这是一个与记事本类似的简单的SDI应用程序,演示了怎样使用MFC来支持 Unicode,对指定的菜单条目进行Turkmenize标签化。实际上,Windwos 2000并不支持Turknen,因此,创建了那些菜单资源以便那些字符串可以在Turknen中显示,为此我必须开发其它的技术。 来源: http://www.codeguru.com/advancedui/SDI_Note.html

  • 平均因子分解法

    平均因子分解法,适用于正定矩阵First, let s recall the definition of the Cholesky decomposition: Given a symmetric positive definite square matrix X, the Cholesky decomposition of X is the factorization X=U U, where U is the square root matrix of X, and satisfies: (1) U U = X (2) U is upper triangular (that is, it has all zeros below the diagonal). It seems that the assumption of positive definiteness is necessary. actually, it is "positive definite" which guarantees the existence of such kind of decomposition.

    This model is just testing an idea of MIMO, which IEEE802.11n will have. But I havo not seen the standard, I tried to make it with 11a. actually this model would not work in real world, because the preambles were not designed to solve the MIMO feature. But this model may be useful to get some idea to start to design a PHY with MIMO.
