nseg
NSEG是美国兰利研究中心推出的飞行器起飞、爬升、巡航、加速、下降、减速和着陆等各个过程分析软件。(NSEG was developed to perform rapid aircraft mission analyses. It is based upon the
use of approximate equations of motion whose form varies with the type of flight
segment. Flight segments considered are takeoff, accelerations, climbs, cruises, descents,
decelerations, and landings. Layered atmosphere options are available. The program can
also be used for flight envelope mapping. NSEG provides the capability to analyze
aircraft missions from low to hypersonic speeds. Realistic and detailed vehicle
characteristics are input to NSEG to permit accurate mission analysis. NSEG allows
engine scaling so as to fit the design under analysis. NSEG contains several approximate
flight path optimization capabilities based on Rutowski energy-like criteria for
considering minimum time or fuel flight segments and maximum range segments during
climb or descent. Takeoff and landing analysis is based on the Air Force Flight
Dynamics Laboratory DATCOM method of high lift aerodynamic modelling)

CoStream 无缓存 Pipe Stream
翻译 maninwest@Codeforge 作者:Sergey Nozhenko@CodeProject介绍：CoStream 是的 PipeStream 无缓存替代选择。背景在生产者/消费者模式下，如果我们知道一个消费者确定要读取stream 读到结束或者如果不能读到结束就处理，那么同步stream 就不需要维护自己的内部缓存，完全依赖于 Read 方法调用者的缓存。在Read 方法中，CoStream 保存到目标缓存的引用并等待，直至完成。而 write 方法从源缓存中复制数据到目标缓存，会给读取者发送信号缓存已准备就绪或者需要等待期 Read 调用（如果来源缓存中有未消耗的数据剩下或者返回到Writer 调用者）。使用代码CoStream 不能在单个话题中使用。应该至少有两个，读取和写入话题。两者都需要关闭（或处理）stream，一边对方可以继续到结束。测试程序在 XmlDocument 中加载了一些 xml 文件。然后将其写入到 CoStream 的实例Static CoStream costream = new TestCoStream();
static string outpath;
static void Main(string[] args)
{
// ...
XmlDocument doc = new XmlDocument();
doc.Load(args[0]);
outpath = args[1];
var reading_thread = new Thread(ReaderBody);
reading_thread.Start();
using (var pipe = XmlWriter.Create(costream, new XmlWriterSettings { CloseOutput = true }))
doc.Save(pipe);
