Abstract New high-speed photonic technologies and co-integration with electronics are required to keep up the demand of future optical communication systems. In this paper, plasmonics is presented as one most promising next-generation that already fulfils these requirements in proof-of-concept demonstrations. Plasmonics features not only modulators detectors highest speed, but also compactness,...

This study estimates three hypotheses of OPEC behavior: market-sharing, target revenue and competitive model for the period 1980 to 2000 for all OPEC courtiers except Iraq. To examine co-integration relation for oil production, we use ADF test in OLS estimation. Also we use ARDL approach to examine these hypotheses and the long run relationship of them. Results indicate none of three hypotheses...

We present a Bayesian framework for parameter inference in noisy, non-stationary, nonlinear, dynamical systems. The technique is implemented in two distinct ways: (i) Lightweight implementation: to be used for on-line analysis, allowing multiple parameter estimation, optimal compensation for dynamical noise, and reconstruction by integration of the hidden dynamical variables, but with some limi...

We have carried out a survey of the dense clumps associated with 14 embedded clusters in the CO (J=1–0) line emission with the Nobeyama 45m telescope in order to understand the formation and evolution of stellar clusters in dense clumps of molecular clouds. We have selected these clusters at distances from 0.3 to 2.1 kpc and have mapped about 6 × 6 to 10 × 10 regions (corresponding to 3.8 pc × ...
