Deformation behavior and its mechanism of Al–Zn–Mg–Cu alloys in different heat treatment states under electrically-assisted uniaxial tension

open access: yesJournal of Materials Research and Technology
Electrically-assisted manufacturing has proven to be an efficient process in improving formability for metal alloys. However, there are relatively few studies on the mechanism of the deformation behavior of Al–Zn–Mg–Cu alloys in different heat-treated ...

Applying Quaternions to Recognize Hidden Details in Images: Rothko as a Case Study

open access: yesMathematical and Computational Applications, 2023
Images or paintings with homogeneous colors may appear dull to the naked eye; however, there may be numerous details in the image that are expressed through subtle changes in color.

A Saliency Detection Model via Fusing Extracted Low-level and High-level Features from an Image [PDF]

open access: yesAUT Journal of Electrical Engineering, 2019
Saliency regions attract more human’s attention than other regions in an image. Low- level and high-level features are utilized in saliency region detection.

Connected Components of Complex Divisor Functions

open access: yes, 2018
For any complex number $c$, define the divisor function $\sigma_c\colon\mathbb N\to\mathbb C$ by $\displaystyle\sigma_c(n)=\sum_{d\mid n}d^c$. Let $\overline{\sigma_c(\mathbb N)}$ denote the topological closure of the range of $\sigma_c$.

Finite connected components in infinite directed and multiplex networks with arbitrary degree distributions [PDF]

open access: yes, 2017
This work presents exact expressions for size distributions of weak/multilayer connected components in two generalisations of the configuration model: networks with directed edges and multiplex networks with arbitrary number of layers.

Connected Components in MapReduce and Beyond [PDF]

open access: yesProceedings of the ACM Symposium on Cloud Computing, 2014
Computing connected components of a graph lies at the core of many data mining algorithms, and is a fundamental subroutine in graph clustering. This problem is well studied, yet many of the algorithms with good theoretical guarantees perform poorly in practice, especially when faced with graphs with hundreds of billions of edges.

Closed models, strongly connected components and Euler graphs

open access: yes, 2016
In this paper, we continue our study of closed models defined in categories of graphs. We construct a closed model defined in the cat-egory of directed graphs which characterizes the strongly connected components.

Connected Components Labeling on DRAGs [PDF]

open access: yes2018 24th International Conference on Pattern Recognition (ICPR), 2018
In this paper we introduce a new Connected Components Labeling (CCL) algorithm which exploits a novel approach to model decision problems as Directed Acyclic Graphs with a root, which will be called Directed Rooted Acyclic Graphs (DRAGs). This structure supports the use of sets of equivalent actions, as required by CCL, and optimally leverages these ...
