Evaluation of Different Spatial Interpolation Methods for IMERG Precipitation Zoning in Neyshabur Basin [PDF]

open access: yesJournal of Hydraulic and Water Engineering, 2023
Direct measurement of continuous spatial data is almost impossible due to the limitations in data collection. To address this issue, many methods have been proposed for data interpolation.

Comparative Analysis of Different Interpolation Methods in Modeling Spatial Distribution of Monthly Precipitation

open access: yesDoğal Afetler ve Çevre Dergisi, 2018
For many water resources planning and management studies such as water budget and hydrological modeling, it is very important to estimate areal precipitation from point observation stations.

Some details of proofs of theorems related to the quantum dynamical Yang-Baxter equation [PDF]

open access: yes, 2000
This paper gives some further details of proofs of some theorems related to the quantum dynamical Yang-Baxter equation. This mainly expands proofs given in "Lectures on the dynamical Yang-Baxter equation" by P. Etingof and O. Schiffmann, math.QA/9908064.

Study on the impact of calculation radius on IDW gravity modelling [PDF]

open access: yesE3S Web of Conferences, 2021
Gravity modelling is a necessary process of applying gravity data to practice, and a vital research area in resource exploring and geodesy. Inverse distance weighted (IDW) interpolation is a widely used algorithm in gravity modelling and many other ...

Haar expectations of ratios of random characteristic polynomials [PDF]

open access: yes, 2016
We compute Haar ensemble averages of ratios of random characteristic polynomials for the classical Lie groups K = O(N), SO(N), and USp(N). To that end, we start from the Clifford-Weyl algebera in its canonical realization on the complex of holomorphic ...

Precipitation interpolation using digital terrain model and multivariate regression in hilly and low mountainous areas of Hungary

open access: yesHungarian Geographical Bulletin, 2021
The relationship between precipitation and elevation is a well-known topic in the field of geography and meteorology. Radar-based precipitation data are often used in hydrologic models, however, they have several inaccuracies, and elevation can be one of

Research on the accessibility to health and educational services in the rural areas in Extremadura

open access: yesEuropean Countryside, 2015
As the competent laws on Health and Education of the Extremaduran Government read, all the Extremaduran people have the right to their benefits, irrespective of their social, economic and cultural characteristics.

Comodule Algebras and 2-Cocycles over the (Braided) Drinfeld Double [PDF]

open access: yes, 2018
We show that for dually paired bialgebras, every comodule algebra over one of the paired bialgebras gives a comodule algebra over their Drinfeld double via a crossed product construction.

A crossvalidation-based comparison of kriging and IDW in local GNSS/levelling quasigeoid modelling

open access: yesReports on Geodesy and Geoinformatics, 2022
This study compares two interpolation methods in the problem of a local GNSS/levelling (quasi) geoid modelling. It uses raw data, no global geopotential model is involved.

Domain walls within domain walls in wide ferromagnetic strips

open access: yes, 2015
We carry out large-scale micromagnetic simulations which demonstrate that due to topological constraints, internal domain walls (Bloch lines) within extended domain walls are more robust than domain walls in nanowires.
