Protothreads are extremely lightweight stackless threads designed for
severely memory constrained systems such as small embedded systems or
sensor network Nodes.
An AHB system is made of masters slaves and interconnections. A general approach to include all possible "muxed" implementation of multi layered AHB systems and arbitrated AHB ones can be thought as an acyclic graph where every source node is a master, every destination node is a slave and every internal node is an arbiter there must
be one and only one arc exiting a master and one or more entering a slave (single slave verus multi-slave or arbitrated slave) an arbiter can have as many input and output connections as needed. A bridge is a special node that collapses one or more slave Nodes and a master node in a new "complex" node.

ML DOM (文檔對(duì)象模型)對(duì)象提供了一個(gè)標(biāo)準(zhǔn)的方法來操作存儲(chǔ)在XML文檔中的信息，這就是DOM應(yīng)用編程接口（API）函數(shù)。它是應(yīng)用程序和XML文檔之間的橋梁。DOM包含兩個(gè)關(guān)鍵的抽象概念：一個(gè)是樹狀的層次結(jié)構(gòu)，另一個(gè)是用來表示文檔內(nèi)容和結(jié)構(gòu)的節(jié)點(diǎn)集合。樹狀層次包括了所有節(jié)點(diǎn)，節(jié)點(diǎn)本身也可以包含其他的節(jié)點(diǎn)。這樣的好處是可以通過這個(gè)層次結(jié)構(gòu)來找到并修改某一特定節(jié)點(diǎn)的信息。 微軟的MSXML解析器讀取一個(gè)XML文檔，然后把它的內(nèi)容解析到一個(gè)抽象的信息容器中，該信息容器被稱為節(jié)點(diǎn)（Nodes）。這些節(jié)點(diǎn)代表文檔的結(jié)構(gòu)和內(nèi)容，并允許應(yīng)用程序來操作文檔中的信息而不需要知道XML的語義。一個(gè)文檔被解析后，它的節(jié)點(diǎn)能夠在任何時(shí)候被瀏覽而不需要保持一定的順序。 對(duì)開發(fā)人員來說，最重要的編程對(duì)象是DOMDocument。 DOMDocument對(duì)象通過暴露的屬性和方法來允許瀏覽、查詢和修改XML文檔的內(nèi)容和結(jié)構(gòu)。 本文主要介紹DOM的結(jié)構(gòu)和應(yīng)用，同時(shí)用VC編程語言給出了通過MSXML進(jìn)行XML解析的實(shí)例。
Programs in the irregular grid design package described in this manual are used to carry out five main functions:
verification and adjustment of coastline and bathymetric data
preparation of an irregular triangular depth grid covering the domain to be modelled
production of a preliminary irregular triangular model grid with Nodes suitably positioned for accurate and efficient numerical modelling
interactive checking and editing, including trimming and joining, of model grid
display and plotting of model output.
北京大學(xué)ACM比賽題目
Consider an infinite full binary search tree (see the figure below), the numbers in the Nodes are 1, 2, 3, .... In a subtree whose root node is X, we can get the minimum number in this subtree by repeating going down the left node until the last level, and we can also find the maximum number by going down the right node. Now you are given some queries as "What are the minimum and maximum numbers in the subtree whose root node is X?" Please try to find answers for there queries.
SimpliciTI™ -1.0.3.exe for CC11xx and CC25xx
SimpliciTI is a simple low-power RF network protocol aimed at small (<256) RF networks. Such networks typically contain battery operated devices which require long battery life, low data rate and low duty cycle and have a limited number of Nodes talking directly to each other or through an access point or range extenders. Access point and range extenders are not required but provide extra functionality such as store and forward messages. With SimpliciTI the MCU resource requirements are minimal which results in the low system cost.
