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協議棧的實現目的，無非是要上層用來實現app的socket編程。好，我們就從socket開始。為了兼容性，lwip的socket應該也是提供標準的socket接口函數，恩，沒錯，在src\inc lude\lwip\socket.h文件中可以看到下面的宏定義：#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，這個結構先不管它，接著看下get socket函數的實現【也是在src\api\socket.c文件中】，在這里我們看到這樣一條語句sock =&sockets[s]；很明顯，返回值也是這個sock它是根據傳進來的序列號在sockets數組中找到對應的元素并返回該元素的地址。好了，那么這個sockets數組是在哪里被賦值了這些元素的呢？進行到這里似乎應該從標準的socket編程的開始，也就是socket函數講起，那我們就順便看一下。它對應的實際實現是下面這個函數Int Iwip socket（int domain，int type，int protocol）【src\api\socket.c】這個函數根據不同的協議類型，也就是函數中的type參數，創建了一個netconn結構體的指針，接著就是用這個指針作為參數調用了alloc socket函數，下面具體看下這個函數的實現
