Effect of graph generation on slope stability analysis based on graph theory

Journal of Rock Mechanics and Geotechnical Engineering, 2014
Limit equilibrium method (LEM) and strength reduction method (SRM) are the most widely used methods for slope stability analysis. However, it can be noted that they both have some limitations in practical application.

Investigating cognitive flexibility deficit in schizophrenia using task-based whole-brain functional connectivity

Frontiers in Psychiatry, 2022
BackgroundCognitive flexibility is a core cognitive control function supported by the brain networks of the whole-brain. Schizophrenic patients show deficits in cognitive flexibility in conditions such as task-switching.

Graph Theory and IC Component Design Analysis

2020 Third International Conference on Artificial Intelligence for Industries (AI4I), 2020
Graph analysis in large integrated circuit (IC) designs is an essential tool for verifying design logic and timing via dynamic timing analysis (DTA). IC designs resemble graphs with each logic gate as a vertex and the conductive connections between gates as edges.

Data-Driven Sequence of Changes to Anatomical Brain Connectivity in Sporadic Alzheimer’s Disease

Frontiers in Neurology, 2017
Model-based investigations of transneuronal spreading mechanisms in neurodegenerative diseases relate the pattern of pathology severity to the brain’s connectivity matrix, which reveals information about how pathology propagates through the connectivity ...
