Exposure Indices of Extreme Wind-Driven Rain Events for Built Heritage

Atmosphere, 2020
Building performance and material change of cultural heritage in urban areas are negatively impacted by wind-driven rain (WDR). The frequency and intensity of WDR exposure are modified by climate change.

Nonstationary extreme value analysis of temperature extremes in China [PDF]

Stochastic Environmental Research and Risk Assessment, 2017
In a changing climate, the common assumption of stationarity of climate extremes has been increasingly challenged, raising the need to incorporate non-stationarity in extreme value modeling. In this study, quantile regression is used to identify the trends of annual temperature extremes and their correlations with two large climate patterns, the ...

EXTREME VALUE ANALYSIS WITHOUT THE LARGEST VALUES: WHAT CAN BE DONE? [PDF]

Probability in the Engineering and Informational Sciences, 2019
AbstractIn this paper, we are concerned with the analysis of heavy-tailed data when a portion of the extreme values is unavailable. This research was motivated by an analysis of the degree distributions in a large social network. The degree distributions of such networks tend to have power law behavior in the tails.

Extreme Value Analysis for Peak Heliostat Wind Load Predictions

SolarPACES Conference Proceedings
This study investigated high-frequency load fluctuations on a rectangular heliostat model in a boundary layer wind tunnel experiment. Statistical methods for peak wind load predictions were compared with load distributions through load cell and surface ...

Spatial and Temporal Clustering Analysis of Extreme Wave Events around the UK Coastline

Journal of Marine Science and Engineering, 2017
Densely populated coastal regions are vulnerable to extreme wave events, which can cause loss of life and considerable damage to coastal infrastructure and ecological assets. Here, an event-based analysis approach, across multiple sites, has been used to

A Spatial Risk Analysis of Springtime Daily Minimum Surface Air Temperature Values for Vineyard Site Selection: Applications to Pinot noir Grapevines throughout the Willamette Valley American Viticultural Area

Agronomy
This study introduced the application of concepts and methods from extreme value theory (EVT) to estimate the probability that daily minimum temperatures exceed springtime critical temperature thresholds for Pinot noir buds and young shoots as a function

A Diagnostic for Selecting the Threshold in Extreme Value Analysis

Journal of the Royal Statistical Society Series B: Statistical Methodology, 2001
Summary A new approach is suggested for choosing the threshold when fitting the Hill estimator of a tail exponent to extreme value data. Our method is based on an easily computed diagnostic, which in turn is founded directly on the Hill estimator itself, ‘symmetrized’ to remove the effect of the tail exponent but designed to emphasize ...
