Sparse estimation in ordinary kriging for functional data
, 2023 We introduce a sparse estimation in the ordinary kriging for functional data. The functional kriging predicts a feature given as a function at a location where the data are not observed by a linear combination of data observed at other locations. To estimate the weights of the linear combination, we apply the lasso-type regularization in minimizing the

International Journal of Climatology, EarlyView.The study provides insights for post‐processing climate model output in complex terrain, useful for climate change impact models. We compared different bias adjustment and downscaling techniques from quantile delta mapping to simple lapse rates. We developed a new spatial downscaling method based on principal components analysis, which showed superior ...

Optimal biased Kriging: Homeogram tapering and applications to geoid undulations in Korea
Journal of Geodetic Science, 2018 This article studies the Optimal Biased Kriging (OBK) approach which is an alternative geostatistical method that gives up the unbiasedness condition of Ordinary Kriging (OK) to gain an improved Mean Squared Prediction Error (MSPE).

From Rare to Recurrent: Intensifying Hot–Dry Extremes Across Romania
International Journal of Climatology, EarlyView.Romania has undergone a marked shift toward more frequent and spatially extensive compound hot–dry months since the 1990s, with persistent hotspots in the eastern Moldavian Plateau and the lower Danube–Bărăgan–Black Sea lowlands and comparatively buffered conditions at higher elevations.

Land Degradation &Development, EarlyView.ABSTRACT Establishing scientifically grounded soil erosion control targets and feasible vegetation restoration strategies is crucial for high quality development of the Chinese Loess Plateau which is severely affected by soil erosion. Currently, the commonly used tolerable soil loss (TSL) is inadequate for addressing the spatial heterogeneity in ...

Ordinary kriging dalam penentuan lama penggalian tambang terbuka
Teknika, 2019 Perkiraan sisa cadangan di PT. Allied Indo Coal Jaya belum dapat dipastikan, karena perhitungan cadangan mengacu pada hasil pemboran eksplorasi yang cukup lama yaitu pada tahun 2008, sehingga perlu adanya evaluasi perhitungan cadangan ulang yang tersedia.
