Hitting minors, subdivisions, and immersions in tournaments [PDF]

Discrete Mathematics & Theoretical Computer Science, 2018
The Erd\H{o}s-P\'osa property relates parameters of covering and packing of combinatorial structures and has been mostly studied in the setting of undirected graphs.

Physics-Informed Directed Graph Network-Based Temperature Forecasting Model [PDF]

Sensors
Recently, there has been a dramatic rise in the demand for accurate temperature forecasts. However, challenges arise from modeling and fusing complex spatial and temporal features in temperature data. In this study, we propose a physics-informed directed-

Directed graph based image registration. [PDF]

Comput Med Imaging Graph, 2012
In this paper, a novel image registration method is proposed to achieve accurate registration between images having large shape differences with the help of a set of appropriate intermediate templates. We first demonstrate that directionality is a key factor in both pairwise image registration and groupwise registration, which is defined in this paper ...

An application-based ontological knowledge base of medications to support health literacy and adherence for the consumer population: an aging population use case [PDF]

Journal of Biomedical Semantics
Background The geriatric population is a vulnerable population that has higher rate of chronic disease and represents the largest portion of healthcare delivered. This population is vulnerable to medication non-adherence. Patient medication non-adherence

CONSTRUCTION OF BICYCLIC GRAPH AND ITS APPLICATION IN TRANS JOGJA ROUTES

Barekeng, 2023
A bicyclic graph is a type of graph that consists of exactly two cycles. A cycle is a graph that is a closed path where no vertices are repeated except the first and last vertices which are the same.

A Node Differential Privacy-Based Method to Preserve Directed Graphs in Wireless Mobile Networks

Applied Sciences, 2023
With the widespread popularity of Wireless Mobile Networks (WMNs) in our daily life, the huge risk to disclose personal privacy of massive graph structure data in WMNs receives more and more attention.

Device Interaction Graph: Directed Decision Graph for Settings Auto-Completion

IEEE Access, 2021
Knowledge generated from appliances usage data can be used for personalizing and reducing the number of user interactions. Appliances such as Washing Machines (WM) are capable of storing the settings data selected by the user, during operation.

Spatio-temporal data prediction of multiple air pollutants in multi-cities based on 4D digraph convolutional neural network.

PLoS ONE, 2023
In response to the problem that current multi-city multi-pollutant prediction methods based on one-dimensional undirected graph neural network models cannot accurately reflect the two-dimensional spatial correlations and directedness, this study proposes

Chained structure of directed graphs with applications to social and transportation networks

Applied Network Science, 2022
The need to determine the structure of a graph arises in many applications. This paper studies directed graphs and defines the notions of $$\ell$$ ℓ -chained and $$\{\ell ,k\}$$ { ℓ , k } -chained directed graphs.
