Optimization of Lithium‐Ion Battery Circular Economy in Electric Vehicles in Sustainable Supply Chain

open access: yesBattery Energy, Volume 4, Issue 2, March 2025.
Lithium batteries constitute a pivotal component in electric vehicles (EVs) owing to their rechargeability and high‐power output capabilities. ABSTRACT Lithium batteries constitute a pivotal component in electric vehicles (EVs) owing to their rechargeability and high‐power output capabilities.

Weighted Versions of the Arithmetic-Mean-Geometric Mean Inequality and Zaremba's Function

open access: yes, 2023
We use the weighted version of the arithmetic-mean-geometric-mean inequality to motivate new results about Zaremba's function, $z(n) = \sum_{d|n} \frac{\log d}{d}$. We investigate record-setting values for $z(n)$ and the related function $v(n) = \frac{z(n)}{\log τ(n)}$ where $τ(n)$ is the number of divisors of $n$.

Sustainability Assessment of Micro, Small, and Medium Enterprises: A Systematic Review and Hybrid Architecture for Credible, Salient, and Legitimate Knowledge Governance

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Sustainability assessment advances corporate social responsibility toward inclusive development. Widely recognized approaches prove inadequate for micro, small, and medium enterprises (MSMEs), resulting in fragmented proliferation that hinders cumulative knowledge.

Applications of Weighted Arithmetic-Geometric Means Inequality to Functional Inequalities

open access: yesJournal of Engineering Technology and Applied Sciences, 2017
In this paper we  prove  the functional  inequality $f(x)^{f(x)}\leq g(x)^{g(x)}$ for positive real functions $f$ and $g$ satisfying natural conditions and apply it to derive inequalities  between some of the elementary functions and to prove monotonocity of certain sequences of real numbers.

Exact Computation of the Color Function for Triangular Element Interfaces

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
We propose a robust algorithm, the Front2VOF algorithm, to compute the color function for triangular element interfaces in Front‐Tracking methods on a Cartesian mesh. ABSTRACT The calculation of the volume enclosed by curved surfaces discretized into triangular elements and a cube is of great importance in different domains, such as computer graphics ...

The role of identification in data‐driven policy iteration: A system theoretic study

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
Abstract The goal of this article is to study fundamental mechanisms behind so‐called indirect and direct data‐driven control for unknown systems. Specifically, we consider policy iteration applied to the linear quadratic regulator problem. Two iterative procedures, where data collected from the system are repeatedly used to compute new estimates of ...

Some new Inequalities for Differentiable Arithmetic-Harmonically Convex Functions

open access: yesKragujevac Journal of Mathematics
In this study, by using an integral identity together with both the Hölder and the power-mean inequalities for integrals we establish several new inequalities for differentiable arithmetic-harmonically-convex function. Also, we give some applications for special means.

Climate Crisis, Human Mobility and Security Challenges in the MENA Region: Implications for Sustainable Development and Regional Stability

open access: yesSustainable Development, EarlyView.
ABSTRACT This study examines the interplay between climate change, violent conflict and forced migration in the Middle East and North Africa (MENA), focusing on asylum flows to the European Union (EU). By integrating high‐resolution climate, conflict and socioeconomic data spanning 2000 to 2023, we develop a comprehensive empirical framework to ...

Localising the Sustainable Development Goals. A Place‐Based Analysis of Sustainable Development in Rural and Urban Areas

open access: yesSustainable Development, EarlyView.
ABSTRACT There are increasing calls for a place‐based approach towards the Sustainable Development Goals that show their territorial diversity at subnational level. Based on 33 indicators, covering 13 SDGs and aggregated in three sub‐indexes (economy, social and environment), this paper develops a Sustainable Development Index for Rural and Urban Areas

Inequalities for multiplicative arithmetic functions

open access: yes, 2011
We study arithmetic inequalities for multiplicative, sub(super)-multiplicative, sub(super)-homogeneous functions. Applications for the classical arithmetic functions are pointed out.
