Abstract In this paper, a decision-making problem with a q-rung orthopair fuzzy hypersoft environment is developed,
and two operators of ordered weighted average and induced ordered weighted average are developed. Several
fundamental features are also derived. The induced ordered weighted average operator is essential in a q-ROFH
environment as the induced ordered aggregation operators are special cases of the existing aggregation operators
that already exist in q-ROFH environments. The main function of these operators is to help decision-makers gain
a complete understanding of uncertain facts. The proposed aggregation operator is applied to a decision-making
problem, with the aim of selecting the… More >

Abstract Recently, the demand for renewable energy has increased due to its environmental and economic needs. Solar
panels are the mainstay for dealing with solar energy and converting it into another form of usable energy. Solar
panels work under suitable climatic conditions that allow the light photons to access the solar cells, as any blocking
of sunlight on these cells causes a halt in the panels work and restricts the carry of these photons. Thus, the panels
are unable to work under these conditions. A layer of snow forms on the solar panels due to snowfall in areas with
low temperatures.… More >

Abstract This paper develops a new numerical framework for mode III crack problems of thin-walled structures by
integrating multiple advanced techniques in the boundary element literature. The details of special crack-tip
elements for displacement and stress are derived. An exponential transformation technique is introduced to
accurately calculate the nearly singular integral, which is the key task of the boundary element simulation of
thin-walled structures. Three numerical experiments with different types of cracks are provided to verify the
performance of the present numerical framework. Numerical results demonstrate that the present scheme is valid
for mode III crack problems of thin-walled structures with… More >

Abstract This research proposes multicriteria decision-making (MCDM)-based real-time Mesenchymal stem cells (MSC)
transfusion framework. The testing phase of the methodology denotes the ability to stick to plastic surfaces, the
upregulation and downregulation of certain surface protein markers, and lastly, the ability to differentiate into
various cell types. First, two scenarios of an enhanced dataset based on a medical perspective were created in the
development phase to produce varying levels of emergency. Second, for real-time monitoring of COVID-19 patients
with different emergency levels (i.e., mild, moderate, severe, and critical), an automated triage algorithm based on a

Abstract Pedo-spectroscopy has the potential to provide valuable information about soil physical, chemical, and biological

Abstract Medical image super-resolution is a fundamental challenge due to absorption and scattering in tissues. These
challenges are increasing the interest in the quality of medical images. Recent research has proven that the rapid
progress in convolutional neural networks (CNNs) has achieved superior performance in the area of medical image
super-resolution. However, the traditional CNN approaches use interpolation techniques as a preprocessing stage
to enlarge low-resolution magnetic resonance (MR) images, adding extra noise in the models and more memory
consumption. Furthermore, conventional deep CNN approaches used layers in series-wise connection to create
the deeper mode, because this later end layer cannot… More >

Abstract The Floyd-Warshall algorithm is frequently used to determine the shortest path between any pair of nodes. It
works well for crisp weights, but the problem arises when weights are vague and uncertain. Let us take an example
of computer networks, where the chosen path might no longer be appropriate due to rapid changes in network
conditions. The optimal path from among all possible courses is chosen in computer networks based on a variety
of parameters. In this paper, we design a new variant of the Floyd-Warshall algorithm that identifies an All-Pair
Shortest Path (APSP) in an uncertain situation of a… More >

Abstract In this article, we highlight a new three-parameter heavy-tailed lifetime distribution that aims to extend the
modeling possibilities of the Lomax distribution. It is called the extended Lomax distribution. The considered
distribution naturally appears as the distribution of a transformation of a random variable following the logweighted power distribution recently introduced for percentage or proportion data analysis purposes. As a result,
its cumulative distribution has the same functional basis as that of the Lomax distribution, but with a novel
special logarithmic term depending on several parameters. The modulation of this logarithmic term reveals new
types of asymetrical shapes, implying a… More >

Abstract The Bald Eagle Search algorithm (BES) is an emerging meta-heuristic algorithm. The algorithm simulates the
hunting behavior of eagles, and obtains an optimal solution through three stages, namely selection stage, search
stage and swooping stage. However, BES tends to drop-in local optimization and the maximum value of search
space needs to be improved. To fill this research gap, we propose an improved bald eagle algorithm (CABES) that
integrates Cauchy mutation and adaptive optimization to improve the performance of BES from local optima.
Firstly, CABES introduces the Cauchy mutation strategy to adjust the step size of the selection stage, to select… More >

Abstract Many complex optimization problems in the real world can easily fall into local optimality and fail to find
the optimal solution, so more new techniques and methods are needed to solve such challenges. Metaheuristic
algorithms have received a lot of attention in recent years because of their efficient performance and simple
structure. Sine Cosine Algorithm (SCA) is a recent Metaheuristic algorithm that is based on two trigonometric
functions Sine & Cosine. However, like all other metaheuristic algorithms, SCA has a slow convergence and may
fail in sub-optimal regions. In this study, an enhanced version of SCA named RDSCA is suggested… More >

Abstract Isogeometric analysis (IGA) is introduced to establish the direct link between computer-aided design and analysis.
It is commonly implemented by Galerkin formulations (isogeometric Galerkin, IGA-G) through the use of
nonuniform rational B-splines (NURBS) basis functions for geometric design and analysis. Another promising
approach, isogeometric collocation (IGA-C), working directly with the strong form of the partial differential
equation (PDE) over the physical domain defined by NURBS geometry, calculates the derivatives of the numerical
solution at the chosen collocation points. In a typical IGA, the knot vector of the NURBS numerical solution is only
determined by the physical domain. A new perspective… More >

Abstract After the excavation of the roadway, the original stress balance is destroyed, resulting in the redistribution of stress
and the formation of an excavation damaged zone (EDZ) around the roadway. The thickness of EDZ is the key
basis for roadway stability discrimination and support structure design, and it is of great engineering significance
to accurately predict the thickness of EDZ. Considering the advantages of machine learning (ML) in dealing with
high-dimensional, nonlinear problems, a hybrid prediction model based on the random forest (RF) algorithm is

Abstract The ablation of ultra-high-temperature ceramics (UTHCs) is a complex physicochemical process including
mechanical behavior, temperature effect, and chemical reactions. In order to realize the structural optimization
and functional design of ultra-high temperature ceramics, a coupled thermo-chemo-mechanical bond-based
peridynamics (PD) model is proposed based on the ZrB2 ceramics oxidation kinetics model and coupled thermomechanical bond-based peridynamics. Compared with the traditional coupled thermo-mechanical model, the
proposed model considers the influence of chemical reaction process on the ablation resistance of ceramic materials.
In order to verify the reliability of the proposed model, the thermo-mechanical coupling model, damage model and
oxidation kinetic model are… More >
