Hybrid Short-term Load Forecasting Method Based on Empirical Wavelet Transform and Bidirectional Long Short-term Memory Neural Networks

引用

Journal of Modern Power Systems and Clean Energy 2022年第5期10卷 1216-1228页

作者： Xiaoyu Zhang Stefanie Kuenzel nicolo Colombo Chris Watkins School of Artificial Intelligence Anhui UniversityHefei 230601China Department of Electronic Engineering Royal HollowayUniversity of LondonEgham HillEgham TW20 OEXUK Department of Computer Science Royal HollowayUniversity of LondonEgham HillEgham TW200EXUK

Accurate short-term load forecasting is essential to modern power systems and smart grids. The utility can better implement demand-side management and operate power system stably with a reliable load forecasting system. The load demand contains a variety of different load components, and different loads operate with different frequencies. The conventional load forecasting methods, e.g., linear regression(LR), auto-regressive integrated moving average(ARIMA), deep neural network, ignore the frequency domain and can only use time-domain load demand as inputs. To make full use of both time-domain and frequency-domain features of the load demand, a load forecasting method based on hybrid empirical wavelet transform(EWT) and deep neural network is proposed in this paper. The proposed method first filters noises via wavelet-based denoising technique, and then decomposes the original load demand into several sub-layers to show the frequency features while the time-domain information is preserved as well. Then, a bidirectional long short-term memory(LSTM) method is trained for each sub-layer independently. In order to better tune the hyperparameters, a Bayesian hyperparameter optimization(BHO) algorithm is adopted in this paper. Three case studies are designed to evaluate the performance of the proposed *** the results, it is found that the proposed method improves the prediction accuracy compared with other load forecasting method.

Locally-advanced prostate cancer in the elderly： should we revisit our treatment paradigms？

引用

Asian Journal of Andrology 2015年第5期17卷 769-770页

作者： Giovanni Lughezzani nicolo Maria Buffi Department of Urology Istituto Clinico HumanitasRozzano Italy

Prostate cancer （PCa） represents the most common malignancy in adult males with an estimated number of 280 000 newly diagnosed cases only in the United States in 2015. Due to the introduction of PSA in clinical practice, the majority of the patients are currently diagnosed with organ-confined and sometimes indolent disease. However, a nonnegligible proportion of individuals are still diagnosed with locally-advanced tumors. In their recently published article, Bekelman et al. focused on elderly patients with locally-advanced PCa in the attempt to determine the best treatment approach in this patient category, and concluded that, even in these individuals, androgen deprivation therapy （ADT） plus radiotherapy （RT） may confer a survival benefit relative to ADT alone. The importance of the current article resides in the fact that it focuses on a patient population that has not been, or has been only scarcely, included in previous studies on the same topic.

Insight of surface treatments for CMOS compatibility of InAs nanowi

Nano Research 2019年第3期12卷 581-586页

作者： Daya S. Dhungana Anne Hemeryck nicolo Sartori Pier-Francesco Fazzini Filadelfo Cristiano Sebastien R. Plissard CNRS LAAS-CNRS Universite de Toulouse F-31400 Toulouse France LPCNO INSA Universite de Toulouse Toulouse France

A CMOS compatible process is prese nted in order to grow self-catalyzed InAs nano wires on silic on by molecular beam epitaxy. The crucial step of this process is a new in-situ surface preparation under hydrogen (gas or plasma) during the substrate degassing combined with an in-situ arsenic ann eali ng prior to growth. Morphological and structural characterizati ons of the InAs nano wires are prese nted and growth mecha nisms are discussed in detail. The major in flue nee of surface termi nation is exposed both experime ntally and theoretically using statistics on ensemble of nanowires and density functional theory (DFT) calculations. The differences observed between Molecular Beam Epitaxy (MBE) and Metal Organic Vapor Phase Epitaxy (MOVPE) growth of I nAs nano wires can be explai ned by these differe nt surfaces termi nations. The transition between a vapor solid (VS) and a vapor liquid solid (VLS) growth mechanism is presented. Optimized growth conditions lead to very high aspect ratio nano wires (up to 50 nm in diameter and 3 micron in len gth) without passi ng the 410℃ thermal limit, which makes the whole process CMOS compatible. Overall, our results suggest a new method for surface preparation and a possible tuning of the growth mechanism using different surface termi nations.
