At present, there is a strong worldwide push toward bringing fiber Closer to indi- vidual homes and businesses. Fiber-to-the-Home/Business (FTTH/B) or Close to it networks are poised to become the next major success story for optical fiber com- munications. In fact, FTTH connections are currently experiencing double-digit or even higher growth rates, e.g., in the United States the annual growth rate was 112% between September 2006 and September 2007, and their presence can add value of U.S. $4,000–15,000 to the selling price of a home.

Recent work has shown that convolutional networks can be substantially deeper, more accurate, and efficient to train if they contain shorter connections between layers Close to the input and those Close to the output. In this paper, we embrace this observation and introduce the Dense Convo- lutional Network (DenseNet), which connects each layer to every other layer in a feed-forward fashion.

This design uses Common-Emitter Amplifier (Class A) with 2N3904 Bipolar Junction Transistor. Use “Voltage Divider Biasing” to reduce the effects of varying β (= ic / ib) (by holding the Base voltage constant) Base Voltage (Vb) = Vcc * [R2 / (R1 + R2)] Use Coupling Capacitors to separate the AC signals from the DC biasing voltage (which only pass AC signals and block any DC component). Use Bypass Capacitor to maintain the Q-point stability. To determine the value of each component, first set Q-point Close to the center position of the load line. (RL is the resistance of the speaker.)

Lwip协议栈的实现目的，无非是要上层用来实现app的socket编程。好，我们就从socket开始。为了兼容性，lwip的socket应该也是提供标准的socket接口函数，恩，没错，在src\inc lude\lwip\socket.h文件中可以看到下面的宏定义：#if LWIP COMPAT SOCKETS#define accept（a，b，c）Iwip accept（a，b，c）#define bind（a，b，c）Iwip bind（a，b，c）#define shutdown（a，b）Iwip shutdown（a，b）#define Closesocket（s）Iwip Close（s）好，这个结构先不管它，接着看下get socket函数的实现【也是在src\api\socket.c文件中】，在这里我们看到这样一条语句sock =&sockets[s]；很明显，返回值也是这个sock它是根据传进来的序列号在sockets数组中找到对应的元素并返回该元素的地址。好了，那么这个sockets数组是在哪里被赋值了这些元素的呢？进行到这里似乎应该从标准的socket编程的开始，也就是socket函数讲起，那我们就顺便看一下。它对应的实际实现是下面这个函数Int Iwip socket（int domain，int type，int protocol）【src\api\socket.c】这个函数根据不同的协议类型，也就是函数中的type参数，创建了一个netconn结构体的指针，接着就是用这个指针作为参数调用了alloc socket函数，下面具体看下这个函数的实现
