Using the TOPSIS method to select the best low-toxicity organic cosolvent for rice-based toxicity tests

open access: yesEcotoxicology and Environmental Safety
The application of low-toxicity cosolvents in phytotoxicity tests is a common technique to enhance the distribution of non-water-soluble organic pollutants in the aqueous phase. In this study, the physiological and biochemical responses of rice seedlings

Application of Multi-Valued Weighting Logical Functions in the Analysis of a Degree of Importance of Construction Parameters on the Example of Hydraulic Valves

open access: yesInternational Journal of Applied Mechanics and Engineering, 2014
In the optimization process, changes in the construction parameters value influence the behaviour of functions depending on time. Weighting logical coefficients for the stabilisation time are taken into consideration here, i.e., a shorter (better ...

Use and optimization of different sources of information for genomic prediction

open access: yesGenetics Selection Evolution, 2017
Background Molecular data is now commonly used to predict breeding values (BV). Various methods to calculate genomic relationship matrices (GRM) have been developed, with some studies proposing regression of coefficients back to the reference matrix of ...

ELM-QR-Based Nonparametric Probabilistic Prediction Method for Wind Power

open access: yesEnergies, 2021
Wind power has significant randomness. Probabilistic prediction of wind power is necessary to solve the problem of safe and stable power grid dispatching with the integration of large-scale wind power. Therefore, this paper proposes a novel nonparametric

An efficient clustering method using weighting coefficients in homogeneous wireless sensor networks

open access: yesAlexandria Engineering Journal, 2018
Due to the type of applications, wireless sensor nodes must always be energy efficient and small. Hence, the presence of constraints such as the limitation of energy resource is inevitable.

A Head-Weighted Gap-Sensitive Correlation Coefficient [PDF]

open access: yesProceedings of the 38th International ACM SIGIR Conference on Research and Development in Information Retrieval, 2015
Information retrieval systems rank documents, and shared-task evaluations yield results that can be used to rank information retrieval systems. Comparing rankings in ways that can yield useful insights is thus an important capability. When making such comparisons, it is often useful to give greater weight to comparisons near the head of a ranked list ...
