Forces and Specific Energy of Polyamide Grinding. [PDF]
Materials (Basel), 2021 This work investigated the grinding process of reinforced and nonreinforced polyamide materials using an Al2O3 grinding wheel. Samples were ground using a custom-made setup of sensors to evaluate in-line temperature, forces, and power. The surface roughness and images were acquired to assess the quality of the final products. The novelty of the work is

Global crop-specific energy demand for irrigation. [PDF]
Nat CommunGlobal irrigation expansion is expected to enhance agricultural productivity in underperforming cultivated areas, yet its associated crop-specific energy requirements remain insufficiently quantified. Here, we present a spatially distributed, physically based framework that estimates crop-specific irrigation energy consumption at 10 km resolution ...

Randić energy of specific graphs [PDF]
Applied Mathematics and Computation, 2015 Let $G$ be a simple graph with vertex set $V(G) = \{v_1, v_2,..., v_n\}$. The Randić matrix of $G$, denoted by $R(G)$, is defined as the $n\times n$ matrix whose $(i,j)$-entry is $(d_id_j)^{\frac{-1}{2}}$ if $v_i$ and $v_j$ are adjacent and $0$ for another cases. Let the eigenvalues of the Randić matrix $R(G)$ be $ρ_1\geq ρ_2\geq ...\geq ρ_n$ which are
