Application of Bonded-Block Models to Rock Failure Analysis

open access: yesApplied Sciences, 2023
Discrete element models are being increasingly applied to model rock failure processes. Bonded-particle models, based on circular or spherical particle systems, have been successfully used for two decades.

Development of point-symmetric modular legged mobile robot capable of operation after falling

open access: yesInternational Journal of Advanced Robotic Systems
This study presents a legged mobile robot based on a regular polyhedral structure that achieves a point-symmetric body configuration. The proposed framework enables dynamic allocation of manipulator roles based on a single reference vector (e.g., gravity)

Polyhedral Approaches to Mixed Integer Linear Programming [PDF]

open access: yes, 2009
This survey presents tools from polyhedral theory that are used in integer programming. It applies them to the study of valid inequalities for mixed integer linear sets, such as Gomory's mixed integer cuts.

Data-Driven Safe Controller Design for LPV Systems with Constant Input Matrix Under Polyhedral and Ellipsoidal Constraints

open access: yesAxioms
This paper proposes a data-driven control design framework for linear parameter-varying (LPV) systems with polyhedral and ellipsoidal constraints, where the input matrix of the system is constant.

A polyhedral approach to planar augmentation and related problems [PDF]

open access: yes, 1995
Given a planar graph G, the planar (biconnectivity) augmentation problem is to add the minimum number of edges to G such that the resulting graph is still planar and biconnected. Given a nonplanar and biconnected graph, the maximum planar biconnected subgraph problem consists of removing the minimum number of edges so that planarity is achieved and ...
