  • 高精度温度测量铂电阻温度探测器(PRTDs)和​​ADC

    Abstract: Many modern industrial, medical, and commercial applications require temperature measurements in the extended temperature rangewith accuracies of ±0.3°C or better, performed with reasonable cost and often with low power consumption. This article explains how platinumresistance temperature detectors (PRTDs) can perform measurements over wide temperature ranges of -200°C to +850°C, with absolute accuracyand repeatability better than ±0.3°C, when used with modern processors capable of resolving nonlinear mathematical equation quickly and costeffectively. This article is the second installment of a series on PRTDs. For the first installment, please read application note 4875, "High-Accuracy Temperature Measurements Call for Platinum Resistance Temperature Detectors (PRTDs) and Precision Delta-Sigma ADCs."

    sheerdns is a master DNS server whose zone records are stored on a One-Record-Per-File bases. Because of this, it is the simplest of any DNS to configure, the easiest to update, and the most efficient for networks that experience a lot of updates (for example master servers for dynamic IP address ranges). You never have to restart it; any updates are available immediately without having to notify the sheerdns process. 来源: http://freshmeat.net/projects/sheerdns/?topic_id=149 sheerdns是一个主DNS服务器,它的域记录保存在一个One-Record-Per-File(每文件一个记录)的库中。因此,它是最简单的DNS配制,最容易更新,对于有大量更新的网络(如动态IP地址范围的主服务器)来说它是最高效的。你不必重新启动它,任何更新不用通知对应DNS进程就可以立即生效。

    Quality, object.oriented architecture is the product of careful study, decision making, and experimentation. At a minimum, the object.oriented architecture process includes farming of requirements, architecture mining, and hands.on experience. Ideally, object.oriented architecture comprises a set of high.quality design decisions that provide benefits throughout the life cycle of the system.

    Although there has been a lot of AVL tree libraries available now, nearly all of them are meant to work in the random access memory(RAM). Some of them do provide some mechanism for dumping the whole tree into a file and loading it back to the memory in order to make data in that tree persistent. It serves well when there s just small amount of data. When the tree is somewhat bigger, the dumping/loading process could take a lengthy time and makes your mission-critical program less efficient. How about an AVL tree that can directly use the disk for data storage ? If there s something like that, we won t need to read through the whole tree in order to pick up just a little bit imformation(a node), but read only the sectors that are neccssary for locating a certain node and the sectors in which that node lies. This is my initial motivation for writing a storage-media independent AVL Tree. However, as you step forth, you would find that it not only works fine with disks but also fine with memorys, too.
