Application of climatological approach to determine the temperature of radiation fogs formation

open access: yesУкраїнський гідрометеорологічний журнал, 2022
The effectiveness of a radiation fog forecast is determined by the accuracy of a forecast for two values – temperature of fog formation and minimum air temperature.

An Introduction to Polynomial and Semi-Algebraic Optimization

open access: yes, 2015
This is the first comprehensive introduction to the powerful moment approach for solving global optimization problems (and some related problems) described by polynomials (and even semi-algebraic functions).

Anomaly polynomial of general 6D SCFTs [PDF]

open access: yes, 2014
We describe a method to determine the anomaly polynomials of general 6d N=(2,0) and N=(1,0) SCFTs, in terms of the anomaly matching on their tensor branches. This method is almost purely field theoretical, and can be applied to all known 6d SCFTs.

Data‐driven forecasting of ship motions in waves using machine learning and dynamic mode decomposition

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.

Proposition of a single-degree-of-freedom experimental modal analysis method considering the effect of mode components close to the target mode

open access: yesNihon Kikai Gakkai ronbunshu, 2020
Modal parameters are sometimes identified by using single-degree-of-freedom (SDOF) methods in the experimental modal analysis, where each resonance peak of the frequency response function (FRF) is considered as a SDOF system.

Polynomial Interpretations over the Natural, Rational and Real Numbers Revisited

open access: yes, 2014
Polynomial interpretations are a useful technique for proving termination of term rewrite systems. They come in various flavors: polynomial interpretations with real, rational and integer coefficients. As to their relationship with respect to termination

From Nature to Engineering: Mortar Volume and Interfacial Mechanics in Bioinspired Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Inspired by natural armors like nacre, this study explores how varying the volume fraction of the soft mortar layer impacts the interfacial strength and toughness of bioinspired ceramics. Experimental and computational analysis reveals that higher mortar volumes increase energy dissipation but reduce interfacial stiffness, offering insights for ...

Powder Metallurgy Preparation of Metastable β Ti–Cr–Ge Alloys for Medical Applications

open access: yesAdvanced Engineering Materials, EarlyView.
This study develops metastable β Ti–Cr–Ge alloys using powder metallurgy for biomedical implants. The Ti–10Cr–2Ge alloy exhibits superior mechanical performance with high yield strength (>1100 MPa), low Young's modulus (<85 GPa), and excellent strain hardening behavior.

A critique of terms and symbols in school mathematics

open access: yesLietuvos Matematikos Rinkinys, 2023
Criticism of some terms and symbols of school mathematics is presented, and recommendations are given. The problem of writing decimal fractions using a comma and the resulting semicolon when separating such numbers, which contradicts not only the ...

A polynomial invariant for knots via von Neumann algebras

open access: yes, 1985
Thus, the trivial link with n components is represented by the pair (l ,n), and the unknot is represented by (si$2 * * • s n i , n) for any n, where si, $2, • • • > sn_i are the usual generators for Bn. The second example shows that the correspondence of
