Amplified fibre delay line with 27 000 recirculations

A Multi-Scale Analysis of 27, 000 Urban Street Networks

OpenStreetMap offers an underexplored source of worldwide geospatial data useful to urban researchers. This study uses the OSMnx software to automatically download and analyze 27,009 US street networks from OpenStreetMap at metropolitan, municipal, and neighborhood scales—namely, every US city and town (N = 19655), census urbanized area (N = 497), and Zillow-defined neighborhood (N = 6857). It ...

A Hessenberg Markov Chain for Fast Fibre Delay Line Length Optimization

In this paper we present an approach to compute the invariant vector of the N + 1 state Markov chain P presented in (Rogiest et al., Lecture Notes in Computer Science, NET-COOP 2007 Special Issue, pp. 4465:185-194) to determine the loss rate of an FDL buffer consisting of N lines, by solving a related Hessenberg system (i.e., a Markov chain skip-free in one direction). This system is obtained b...

Performance Analysis of Optical Fibre Delay Line Buffers and DOCSIS Cable Modem Networks

O - line Digit Recognition with Time Delay

Automatic computer recognition of arbitrary handwritten characters remains as one of the more elusive targets for computer researchers. Methods incorporating knowledge of time-sequencing of data point inputs have achieved some success, but are not generally applicable to real-world applications where such time-dependency information is often not available. Using a simple algorithm for synthesiz...

Line-mixing in the 106—000 overtone transition of HCN

By using cavity ring-down spectroscopy ~CRDS!, we have obtained visible overtone absorption spectra of HCN which display a large collisional line-mixing effect in the proximity of the R branch band heads, for J;18. We consider in detail the 106←000 ~15CN, 05bend, 65CH! parallel transition. The R branch profile was modeled using the modified-exponential-gap ~MEG! and energy-corrected-sudden appr...
