The Euro-Mediterranean Center on Climate Change (CMCC) decadal prediction system [PDF]

open access: yesGeoscientific Model Development, 2023
Decadal climate predictions, obtained by constraining the initial condition of a dynamical model through a truthful estimate of the observed climate state, provide an accurate assessment of near-term climate change and are a useful tool to inform ...

EEG Decoding Based on Wavelet Transform and Common Space Pattern [PDF]

open access: yesZhengzhou Daxue xuebao. Gongxue ban, 2022
Aiming at the problem of fewer tasks and low accuracy of recognition for motion imagination electroencephalogram(EEG)signals, in this paper a common space pattern(CSP)method based on wavelet packet decomposition(WPD)was proposed to extract the features

Local resolution of currents through electrical joints consisting of materials with different conductivity

open access: yesEPJ Photovoltaics, 2023
Within this work the impact of contact materials with higher volume resistivity as leaded solder are investigated in terms of comparability of the current conduction through the joint. An approach was developed to experimentally determine the qualitative

Small Promise CSPs that reduce to large CSPs

open access: yesLogical Methods in Computer Science, 2022
For relational structures A, B of the same signature, the Promise Constraint Satisfaction Problem PCSP(A,B) asks whether a given input structure maps homomorphically to A or does not even map to B. We are promised that the input satisfies exactly one of these two cases.

Quantification of UV protecting additives in ethylene-vinyl acetate copolymer encapsulants for photovoltaic modules with pyrolysis-gas chromatography-mass spectrometry

open access: yesPolymer Testing, 2023
Reliability of polymeric encapsulants is being assured using suitable additives. Especially UV absorbers and UV stabilizers are important to protect the encapsulants from solar radiation.

On regularity of Max-CSPs and Min-CSPs

open access: yesInformation Processing Letters, 2022
We study approximability of regular constraint satisfaction problems, i.e., CSPs where each variable in an instance has the same number of occurrences. In particular, we show that for any CSP $Λ$, existence of an $α$ approximation algorithm for unweighted regular Max-CSP $Λ$ implies existence of an $α-o(1)$ approximation algorithm for weighted Max-CSP $

Compilation-Based Approaches to Parallel Planning: An Empirical Comparison

open access: yesProceedings of the International Florida Artificial Intelligence Research Society Conference, 2021
Automated planning deals with finding a sequence of actions, a plan, to reach a goal. One of the possible approaches to automated planning is a compilation of a planning problem to a Boolean satisfiability problem or to a constraint satisfaction problem,
