This study has discussed some shortages of IP over SDH used currently, and has proposed the necessities of IP over DWDM. It has given the structure of IP over DWDM, and has explained why it can increase its bandwidth when transiting IP packets over DWDM. The study has also discussed the two methods of realizing IP over DWDM transmission network.

Context. 55 Cnc e is in a 0.73 day orbit transiting Sun-like star. It has been observed that the occultation depth of this super-Earth, with mass 8 M ? and radius 2 R , changes significantly over time at mid-infrared wavelengths. Observations Spitzer measured change its day-side brightness temperature 1200 K, possibly driven by volcanic activity, magnetic star-planet interaction, or presence ci...

Many problems in mathematics and science require the use of infinite-dimensional spaces. Consequently, there is need for an analogue of the finite-dimensional notions of ‘Lebesgue almost every’ and ‘Lebesgue measure zero’ in the infinite-dimensional setting. The theory of prevalence addresses this need and provides a powerful framework for describing generic behavior in a probabilistic way. We ...

Electronic order book trading has evolved in being recognized as the best-practice for trading small and mid-sized orders. Yet, this mechanism does not properly address the needs of large-sized orders which tend to execute off order book in over-the-counter markets. Order book trading provides for public price discovery but not for quantity discovery. Off book executions generally fragment the ...

The high barriers to entry in the former elite telecom industry have been torn down, leaving a brutally competitive market, where over-the-top (OTT) providers like Vonage, Skype, Netflix and others, with no desire to own a network, provide offerings that ride on top of CSP networks.

The discovery of transiting extrasolar planets has enabled us a number of interesting stduies. Transit photometry reveals the radius and the orbital inclination of transiting planets, and thereby we can learn the true mass and the density of respective planets by the combined information of radial velocity measurements. In addition, follow-up observations of transiting planets such as secondary...

The Near Earth Object Surveillance Satellite (NEOSSat) is a Canadian-led 15 cm Earth-orbiting telescope originally designed to detect asteroids near the Sun. Its design however also suitable for observation of exoplanetary transits bright stars. We used NEOSSat platform perform followup observations several Transiting Exoplanets Survey (TESS) targets, both as demonstration capabilities science ...
