The restrained double Roman domination and graph operations

A restrained double Roman dominating function (RDRD-function) on a graph G is a function f:V(G)→{0, 1, 2, 3} that satisfies two conditions: (1) If f(v)

Extended batch adsorber analogue model (e‐BAAM) for rapid evaluation of CO2 capture pressure swing adsorption cycles

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This work presents a simplified extended‐batch adsorber analogue model (e‐BAAM) to quantify key performance metrics such as purity, recovery, and energy trends for various pressure swing adsorption (PSA) process cycles for CO2$$ {\mathrm{CO}}_2 $$ capture.

Edge-Cost double Roman domination

Central European Journal of Operations Research
We introduce the Edge-Cost double Roman domination problem, a generalization of the standard double Roman domination (DRD) problem. While the standard DRD problem focuses only on the number of units placed on vertices of an undirected graph to guarantee “double Roman” level of security, Edge-Cost double Roman domination additionally incorporates the ...

Digitalization in Sustainability Reporting and Text Attributes of Non‐Financial Disclosure: Evidence From Italian Listed Companies

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Recent regulatory initiatives, including the EU Corporate Sustainability Reporting Directive (CSRD), are reinforcing the demand for more structured, transparent, and accessible sustainability reporting. However, empirical evidence on how digital tools influence the narrative dimension of these disclosures remains limited.

An Intensity Measure‐Based Methodology for Ground Motion Orientation in Seismic Structural Assessment

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT In current dynamic time history assessment protocols, ground motion recordings are mostly oriented along fixed sensor directions. Consequently, the orientation of the principal resultant of rupture energy, which may control the maximum structural demand, remains undefined, precluding consistent correlation with physically detrimental ...

Independent Double Roman Domination on Block Graphs

CoRR, 2019
Given a graph $G=(V,E)$, $f:V \rightarrow \{0,1,2 \}$ is the Italian dominating function of $G$ if $f$ satisfies $\sum_{u \in N(v)}f(u) \geq 2$ when $f(v)=0$. Denote $w(f)=\sum_{v \in V}f(v)$ as the weight of $f$. Let $V_i=\{v:f(v)=i\},i=0,1,2$, we call $f$ the independent Italian dominating function if $V_1 \cup V_2$ is an independent set.

Roman Domination in Complementary Prism Graphs [PDF]

, 2012
A Roman domination function on a complementary prism graph GGc is a function f : V [ V c ! {0, 1, 2} such that every vertex with label 0 has a neighbor with label 2. The Roman domination number R(GGc) of a graph G = (V,E) is the minimum of Px2V [V c f(x)
