Abstract:
A graph G is said to be SD-harmonious labeling if there exists an injection f: V(G) -> {0,1,2,...,q} such that the induced function f*: E(G) ->{0,2,...,2q-2} defined by f(uv)=S+D (mod 2q) is bijective, where S=f(u)+f(v) and D=|f(u)-f(v)|, for every edge uv in E(G). A graph which admits SD-harmonious labeling is called SD-harmonious graph. In this paper, we investigate SD-harmonious labeling of path related graphs, tree related graphs, star related graphs and disjoint union of graphs.

Abstract:
We consider in this work a new approach to study the simultaneous strong metric dimension of graphs families, while introducing the simultaneous version of the strong resolving graph. In concordance, we consider here connected graphs G whose vertex sets are represented as V ( G ) , and the following terminology. Two vertices u , v ∈ V ( G ) are strongly resolved by a vertex w ∈ V ( G ) , if there is a shortest w − v path containing u or a shortest w − u containing v. A set A of vertices of the graph G is said to be a strong metric generator for G if every two vertices of G are strongly resolve

Abstract:
In the context of scheduling class timetables and allocating teachers to specific subjects in schools, a common issue is the occurrence of schedule conflicts. These conflicts often result in situations where a teacher is assigned to teach the same subject at the same time in different classes, or where teachers are scheduled to teach different subjects simultaneously. The Welch Powell algorithm is a graph coloring method that can be applied to scheduling problems. The scheduling process begins by representing subjects and the teachers assigned to them as a graph. Each subject is represented as

A set S of vertices of a graph G is a total outer-connected dominating set if every vertex in V(G) is adjacent to some vertex in S and the subgraph G[V\S] induced by V\S is connected. The total outer-connected domination numberγ toc (G) is the minimum size of such a set. The total outer-connected domination subdivision number sd γ toc (G) is the minimum number of edges that must be subdivided in order to increase the total outer-connected domination number. We prove the existence of sd γ toc (G) for every connected graph G of order at least 3 and give upper bounds on it in some classes of grap

Abstract:
Stock ranking prediction is an effective method for achieving a high investment return and plays a crucial role in investment decisions. However, previous studies have overlooked the interconnections among stocks or have solely relied on predefined graphs for stock relationship information. The predefined graphs may not capture all possible relationships and may not be suitable for describing dynamic relationships. To address these issues, we propose a Static-Dynamic hypergraph neural network framework based on Residual Learning (SD-RL). Compared with traditional methods, SD-RL has the followi

Abstract:
A fair dominating set (FDS) J is a dominating set of a graph H, such that all vertices in V \J are dominated by the same number of vertices of J. The fair domination number (FDN) is the minimum cardinality of a fair dominating set of H, denoted by γ_fd (H). The domination subdivision number (FDSN) 〖Sd〗_γ (H), represents the smallest number of edges in H that needs to be subdivided (with each edge being subdivided at most once) to increase the domination number of the graph. The fair domination subdivision number, 〖Sd〗_(γ_fd)^+ (H) (or 〖Sd〗_(γ_fd)^- (H)) is the minimum number of edge subdivisio

The paper proposes a presentation of D-graphsand SD-graphs by a defining pair of words in the alphabet of their vertex labels.

We alsopresent an algorithm for constructing a canonical defining pair fora D-graph and find some numerical estimates of this pair.

Abstract:
Stochastic methods are used to model the topological operating environment of an autonomous mobile agent that performs goal-directed movement or navigation. For successful navigation, it is necessary to efficiently represent information about the environment, i.e. to create its map. The topological representation focuses on the structural characteristics of the environment and the connections between different areas of space. The model of this representation is a graph, where vertices represent important locations and edges represent possible paths between them. In this paper, the environment

The task of automatically segmenting 3-D surfaces representing object boundaries is important in quantitative analysis of volumetric images, which plays a vital role in numerous biomedical applications. For the diagnosis and management of disease, segmentation of images of organs and tissues is a crucial step for the quantification of medical images. Segmentation finds the boundaries or, limited to the 3-D case, the surfaces, that separate regions, tissues or areas of an image, and it is essential that these boundaries approximate the true boundary, typically by human experts, as closely as po

Glaucoma is the second leading cause of blindness worldwide. The clinical standard for monitoring the functional deficits in the retina that are caused by glaucoma is the visual field test.

The characteristic changes of retinal structures such as the optic nerve head (ONH) are monitored utilizing imaging modalities such as color (stereo) fundus photography and, more recently, spectral-domain optical coherence
