Graphs with no induced wheel or antiwheel
CoRR, 2015 A wheel is a graph that consists of a chordless cycle of length at least 4 plus a vertex with at least three neighbors on the cycle. It was shown recently that detecting induced wheels is an NP-complete problem. In contrast, it is shown here that graphs that contain no wheel and no antiwheel have a very simple structure and consequently can be ...

Modal Analysis of In-Wheel Motor-Driven Electric Vehicle Based on Bond Graph Theory
Shock and Vibration, 2017 A half-car vibration model of an electric vehicle driven by rear in-wheel motors was developed using bond graph theory and the modular modeling method. Based on the bond graph model, modal analysis was carried out to study the vibration characteristics ...

On Generalized Topological Indices for Some Special Graphs
Journal of Mathematics, 2022 Topological indices are numeric values associated with a graph and characterize its structure. There are various topological indices in graph theory such as degree-based, distance-based, and counting-related topological indices.

Advanced Robotics Research, EarlyView.Here, we present a textile, wearable capacitive interface enabling multidirectional remote control by dynamically modulating electrode overlap and spacing via a freely gliding upper electrode. A forearm‐mounted prototype drives robotic and media tasks with 12–15 ms latency, maintains < 0.8% drift after 500 cycles, and remains stably functional at 90 ...

The coalescence of multi-wheel and starlike graphs is DLS [PDF]
Journal of Mahani Mathematical ResearchThe Laplacian spectrum of a graph is obtained by taking the difference of the adjacency spectrum from the diagonal matrix of degrees. If a graph has a unique Laplacian spectrum, it means that it can be identified by this spectrum, it is called $DLS ...

The structure of (theta, pyramid, 1‐wheel, 3‐wheel)‐free graphs [PDF]
Journal of Graph Theory, 2018 AbstractIn this paper, we study the class of graphs defined by excluding the following structures as induced subgraphs: theta, pyramid, 1‐wheel, and 3‐wheel. We describe the structure of graphs in , and we give a polynomial‐time recognition algorithm for this class. We also prove that ‐free graphs in are 4‐colorable.

Data‐Driven Bulldozer Blade Control for Autonomous Terrain Leveling
Advanced Robotics Research, EarlyView.A simulation‐driven framework for autonomous bulldozer leveling is presented, combining high‐fidelity terramechanics simulation with a neural‐network‐based reduced‐order model. Gradient‐based optimization enables efficient, low‐level blade control that balances leveling quality and operation time.
