Jurnal sport science, 2020
The use of technology has been proposed to improve decision-making in sport officials. The implementation of the video Assistant Referee (VAR) in association football is one example of how technology can be used to assist decision making, although its ...

Hourly 4D‐Var in the Met Office UKV operational forecast model
Quarterly Journal of the Royal Meteorological Society, 2020Hourly cycling four‐dimensional variational data assimilation (4D‐Var) was implemented operationally in the Met Office's convective‐scale UKV forecast model in July 2017, replacing the previous three‐hourly cycling three‐dimensional 3D‐Var scheme.

Three-Stage Robust Inverter-Based Voltage/Var Control for Distribution Networks With High-Level PV
IEEE Transactions on Smart Grid, 2019This paper proposes a novel three-stage robust inverter-based voltage/var control (TRI-VVC) approach for high photovoltaic (PV)-penetrated distribution networks.

The Journal of Portfolio Management, 2003
When considering how much leverage to use with a real estate portfolio, a good risk measure is needed to evaluate the risk-reward trade-off. The Sharpe ratio, which is not very sensitive to changes in leverage, masks the very different risk/return combinations created by various levels of debt. The authors argue that Value at Risk (VaR) is a far better

Robust Volt/VAr Control With Photovoltaics
IEEE Transactions on Power Systems, 2019The new IEEE 1547-2018 standard includes dynamic Volt/VAr control for photovoltaic (PV) smart inverters. While recent research has addressed the problem of optimal inverter dispatch, the interaction between inverters and the classical Volt/VAr control ...

Review of Financial Economics, 2002
AbstractSince “Value at Risk” (VaR) received its first wide introduction in the July 1993 Group of Thirty report, the number of users of—and uses for—VaR have increased dramatically. However, VaR itself has been evolving. In this article, we will first review some of the important refinements in VaR that have appeared—improved speed of computation ...
