The probability distribution of wind speed and availability of wind farms are investigated considering the vertical wind shear. Wind speed at extended height (60 m) was generated from that of reference height (10 m) through the Power-law Process. The least square (LS) method, maximum likelihood estimation (MLE) method and modified method are used to estimate the parameters of Weibull distribution...
Evanescent-coupling-induced group velocity dispersion (GVD) in a subwavelength silicon directional coupler is observed to significantly modify four-wave-mixing (FWM) spectra. As the separation between two silicon wires decreases, the increasing dispersion gradually suppresses the FWM gain.
Silicon photonics has attracted much attention [1]. While spectral measurements of nonlinear processes in subwavelength silicon-on-insulator (SOI) waveguides have been well reported, time-domain or simultaneous time-and-frequency characterization is required to fully characterize effects like soliton formation [2,3].
Silicon on insulator photonic wire waveguides offer tight sub-wavelength confinement of light, high nonlinearities and large and controllable geometrical Group Velocity Dispersion (GVD) [1]. Arranging wires in arrays brings about new opportunities for dispersion control. Strongly dispersive coupling between modes of adjacent wires causes substantial and controllable variation of the zero GVD wavelength...
Numerical simulations and experimental measurements to plasmon resonances in Ag Bowtie nanoantennas show that, as the bow angle increases, one fundamental resonance blue- and then red-shifts; two types of high-order resonances emerge at large angles.
Spectral broadening in an array of subwavelength silicon waveguides pumped with fs pulses is studied. Adjusting input pulse position, different spectral patterns are observed and explained using the resonant emission from temporal supermode solitons.
Time-domain measurements of dispersion- and nonlinearity-induced chirpings of femtosecond pulses in silicon-on-insulator nanowires reveal nonlinear dispersion compensation. Spectral measurements show pronounced dispersive wave emission by solitons.
The IEC 61499 Function Block is an open standard for distributed control and automation. However, work related to using IEC61499 as code generator for various programming languages is still lacking. In this paper, a methodology for code generation based on XML and EBNF is discussed. Along with this code generator, an Iterative Knowledge Based Data Library (IKBDL) is proposed to improve the accuracy...
By analyzing application protocols and traffic, we find that the most striking distinguish between BitTorrent (BT)-like peer-to-peer (P2P) applications' traffic and traditional as well as other P2P (such as Skype) applications' traffic of a single user may be the dissimilarity in the distribution of remote hosts involved. Therefore, we propose a method based on discreteness of remote hosts (RHD) to...
A one-dimensional photonic crystal microcavity filter that transmits light simultaneously at several wavelengths has been designed and fabricated. Transmission peaks occurred at 1168, 1321 and 1562 nm wavelengths, meeting the design specification.
