bandwidth range
Examples
- According to the definitions of bottleneck bandwidth , available bandwidth and bulk transfer capacity , we analyzed the algorithms which named vps ( variable packet size ) , pptd ( packet pair / train dispersion ) , slops ( self - loading periodic streams ) and topp ( trains of packet pairs ) ; based on the principle of sub - path bottleneck measurement , we developed the bottleneck measurement algorithm using heterogenous packet - pair train ; after designing the three child algorithms ( demarcating bandwidth range , approaching bandwidth value and predicting the trendency of available bandwidth fluctuation ) , we performed the algorithm called self - loading binary search ; applying the multi - home properties of sctp ( stream controltransmission protocol ) and measurement algorithm of available bandwidth , we presented a scheme to adjust the sctp transport path when there are network congestions or faults ; by the library of winsock and winpcap , we developed a measurement program to look for bottleneck bandwidth . in ns2 experiments , the algorithm based on heterogenous packet - pair train fitted well , and the algorithm of self - loading binary search worked quickly , and the sctp scheme improved the throughput effectively

如今国产的手持式示波器已经能够实现数字示波器的功能,例如能够实时的显示出一定带宽范围内的信号波形以及其参数,可以选择耦合的方式等等,还添加了万用表的一些功能,所以也被称为示波表。 - Measurement and characterization of surface texture is an important aspect of precision metrology . historically this has involved partitioning a profile into different wavelength regimes referred to as roughness , waviness and form followed by numerical quantization . parameters computed are then inspected for tolerance compliance to ensure a part performs its intended function . this approach is satisfactory when the specification has been carefully determined and the process is stable . however , when the manufacturing process is under development or when instability or modifications to the process invalidate specifications , there is a need to study surface finish parameters in relation to functional performance or process measures . in this context , the problem of surface texture classification and recognition are discussed . advanced techniques developed for this purpose along with applications are presented . also , the techniques discussed here will be useful across large bandwidth , from the characterization of nano scale to traditional micro scale surfaces
表面结构的测量与特征描述是精密计量技术的一个重要方面,传统上包括将轮廓情况根据不同的波长范围划分为粗糙度、波纹度和形状及后续的数字量化.按算得的参数检查它是否为公差允许,以保证零件执行其指定的功能.当技术特性已经经过仔细确定,并且其过程稳定时,该方法是令人满意的;但是,当制造过程正在进行中或过程的不稳定、过程变化使技术特性失效时,就需要研究和功能表现及过程评定相关的表面参数.讨论了表面结构的分类与识别问题.同时阐述了为此目的而开发的先进技术及其应用.所研究的技术对从纳米尺度到传统的微米尺度的较大带宽范围内的表面特征描述都是有效的
