Multi-dimensional scenario forecast for generation of multiple wind farms

Journal of Modern Power Systems and Clean Energy, 2015
A novel multi-dimensional scenario forecast approach which can capture the dynamic temporal-spatial interdependence relation among the outputs of multiple wind farms is proposed.

Synchronous asynchronous encounter analysis of runoff between reservoirs based on Copula function [PDF]

, 2019
Based on goodness-of-fit test on Copula function, we got the best fitted joint distribution function of runoff between D and H reservoirs. Then we analyzed the synchronous asynchronous encounter probability of runoff.

Prediction and Risk Assessment of Extreme Weather Events Based on Gumbel Copula Function

, 2022
Damage caused by climate catastrophes is severe, especially for the 1-in-100-year events. This study is aimed at assessing the frequency and spatiotemporal regularity of extreme weather events.

Translating Sustainable Development Goals‐Oriented Business Practices Into Sustainable Development: Practice Maturity, Managerial Gender, and Organizational Results

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Despite growing interest in SDG‐oriented business practices, limited attention has been paid to how practice maturity and managerial gender jointly shape the translation of sustainability initiatives into Sustainable Development and organizational results.

Self‐Reported Versus Objectively Logged Social Media Use: Implications for Measurement in Eating Disorder Research

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Self‐reported frequency measures of social media use (e.g., “How often do you use social media?”) are convenient, yet their criterion validity against objective behavioral data remains largely untested in eating disorder research. We compared self‐reports of TikTok use with objective data extracted from TikTok datafiles.

Point and Risk estImation Using an enSemble of Models for Nowcasting: PRISM‐Now

Journal of Forecasting, EarlyView.
ABSTRACT We propose PRISM‐Now, a novel ensemble forecasting system for near‐term GDP projection. Recognizing that relevant economic information evolves over time, we treat forecasts from multiple base models as draws from a mixture distribution of “good” and “bad” estimates, whose composition changes continuously and cannot be identified ex ante.

Brexit and Its Impact on EU Financial Markets

International Journal of Finance &Economics, EarlyView.
ABSTRACT We investigate the impact of Brexit on volatility spillovers across the EU countries. We introduce a Brexit intensity measure that assigns an intensity score reflective of the financial markets' reaction to the events that occurred as Brexit negotiations began to unfold.

Fitting Copulas with Maximal Entropy

Entropy
We deal with two-dimensional copulas from the perspective of their differential entropy. We formulate a problem of finding a copula with maximum differential entropy when some copula values are given.

Spatiotemporal Changes and Climate Driving Factors of Compound Precipitation‐Temperature Extreme Events Across Global Land Areas

International Journal of Climatology, EarlyView.
During the period 1901–2024, the dominant proportion of compound dry‐warm extremes in annual, June–July–August (JJA), and December–January–February (DJF) occurrences was the highest among the four types of compound precipitation and temperature extremes across global land areas, accounting for 40.1%, 50.3%, and 28.0%, respectively.
