Parameter identification is an important method to establish the governing system of a pumped storage unit. Appropriate parameters will make obtain better control performance. Therefore, in this study, improved artificial hummingbird algorithm (IAHA) proposed for parameter The integrates two key strategies improve optimization ability algorithm. First, Chebyshev chaotic map employed initialize ...

We propose a simple model based on the Gnedenko limit theorem for simulation and studies of the ordinary Levy motion, that is, a random process, whose increments are independent and distributed with a stable probability law. We use the generalized structure function for characterizing anomalous diffusion rate and propose to explore the modified Hurst method for empirical rescaled range analysis...

In this paper, the virtual flight simulation environment for open-source-based avionics test system design and implementation. This paper is proposing an integrated avionics test system for flight manipulation and simulation using the commercial simulation and development software tools such as X-Plane, LabView, and Google Earth. The proposed system is designed of seven parts of user flight con...

This paper revisits Levy sections theorem, which generalizes the central limit theorem to encompass autocorrelated variables. Levy sections theorem’s approach is extended to time series and applied to historical daily returns of selected dollar exchange rates. We explain the elevated kurtosis usually observed in such series by their volatilities. In particular, the high kurtosis of emerging mar...

We recall four open problems concerning constructing high-order matrixexponential approximations for the infimum of a spectrally negative Levy process (with applications to first-passage/ruin probabilities, the waiting time distribution in the M/G/1 queue, pricing of barrier options, etc). On the way, we provide a new approximation, for the perturbed CramérLundberg model, and recall a remarkabl...

Plane block parallel blocking flowline is a special flowline, which can also be called incomplete hybrid flowline. However, the existing scheduling work has less research on this problem and lacks constraint of considering deterioration effect. Therefore, paper studies plane effect (PBFSP-DE). This typical NP hard problem, so proposes Hybrid Whale Optimization Algorithm (HWOA) for problem. In H...

Abstract In the short-term power load prediction, environmental uncertainty will have an impact on prediction accuracy and increase complexity of prediction. To deal with this problem, paper proposes a bidirectional gated recurrent unit (BiGRU) network model for sine cosine optimization algorithm self-learning strategy Levy flight (SCASL). With real data as set, high correlation parameters are ...
