Approach To Multi-Criteria Decision-Making In A Neutrosophic Picture Hyper-Soft Set Environment Using Generalized Neutrosophic Topsis, Manpreet Kaur, Akanksha Singh
Neutrosophic Sets and Systems
Given the complexity of today’s world, we might need to work with numbers requiring multi-attribute functions, such as those having positive, neutral, and negative membership and those having truth, indeterminacy, and falsity membership. Adding these numbers together to get a single real number is the most important factor. In situations like this, decision-makers have more difficult choices and are unable to apply the single attribute function of the soft set theory. To address this constraint, the hyper-soft set theory with multi-attribute functions is introduced. We combine the notion of neutrosophic hypersoft set with picture fuzzy hypersoft set to form a …

Physical And Stochiometric Controls On Nutrient Uptake And Ecosystem Respiration In Contrasting Sites, Jancoba K. Dorley
Civil Engineering ETDs
Meteorological, hydrological, and biogeochemical processes naturally control stream ecosystems. These processes define the frequency and distribution of precipitation and the supply and demand of solutes and particles to support aquatic food chains through space and time. Studies have also found that stream ecosystems are also controlled by anthropogenic activities, which occur on a much shorter timescale. These anthropogenic activities affect stream ecosystems' structure and function from local to planetary changes to the environment. It is essential for scientists and engineers to understand the relationships between naturally occurring processes and those created by human activities for a better interpretation of stream …

Solving The Minimum Spanning Tree Problem Under Interval-Valued Fermatean Neutrosophic Domain, Souhail Dhouib, Vidhya K, Said Broumi, Mohamed Talea
Neutrosophic Sets and Systems
In classical graph theory, the minimal spanning tree (MST) is a subgraph that lacks cycles and efficiently connects every vertex by utilizing edges with the minimum weights. The computation of a minimum spanning tree for a graph has been a pervasive problem over time. However, in practical scenarios, uncertainty often arises in the form of fuzzy edge weights, leading to the emergence of the Fuzzy Minimum Spanning Tree (FMST). This specialized approach is adept at managing the inherent uncertainty present in edge weights within a fuzzy graph, a situation commonly encountered in real-world applications. This study introduces the initial optimization …

Microcapsule Transport And Blockage In Rough-Walled Fractures, Brittney Diana Seaburn
Civil Engineering ETDs
Thermal short-circuiting is a potential problem for Enhanced Geothermal Systems (EGS). One solution to this problem is to reduce the permeability of very conductive fractures with thermally degradable microcapsules carrying porous polymers that bond to rock, reducing fluid flow without completely sealing the fracture. This concept requires microcapsules to principally travel in the larger, problematic fractures, minimizing entry into smaller fractures; consequently, understanding the transport and blockage of microcapsules is critical. Using a flow visualization configuration, this study involved quantifying the transport and blockage of microcapsules in transparent fracture replicas. Analyses determined most blockage occurred in regions with local apertures …
