Research on the complex dynamical behavior of H-bridge inverter with RLC load

Scientific Reports
Complex dynamical behaviors such as bifurcation and chaos exist in H-bridge inverter with RLC load, and these nonlinear behaviors will greatly increase the harmonic content of the output current and reduce the stability and reliability of the system.

The computation of disconnected bifurcation diagrams

, 2016
Arclength continuation and branch switching are enormously successful algorithms for the computation of bifurcation diagrams. Nevertheless, their combination suffers from three significant disadvantages. The first is that they attempt to compute only the part of the diagram that is continuously connected to the initial data; disconnected branches are ...

NiFe‐NO3 Layered Double Hydroxide as a Novel Anode for Sodium Ion Batteries

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
This study demonstrates, for the first time, the effectiveness of using LDH as an anodic material in SIB. The material is stable and show high specific capacity, the reaction mechanism has been thoroughly investigated and comprehensively described and involves a phase change reaction followed by sodium intercalation.

Qualitative bifurcation diagrams

, 2014
This thesis explores the use of qualitative reasoning to predict the behavior of a dynamical system given a change in one of its parameters based upon a qualitative representation of its bifurcation diagram. Three algorithms were developed to perform this task.

Grooved Surface of the Obturator Internus Muscle With Two Distinct Adjacent Parts

Clinical Anatomy, EarlyView.
ABSTRACT The specific anatomical features of the obturator internus, particularly those of its medial surface, remain insufficiently characterized. This study investigated the morphology of the obturator internus muscle by focusing on the shape of its medial surface and potential age‐related changes.

Mechanistic Insights Into How Rewiring and Bifurcation Angle Affect DK‐Crush Stent Deployment

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Double kissing crush (DKC) is a preferred two‐stent technique for complex coronary bifurcation lesions. Proximal cell rewiring is routinely recommended to reduce technical failure, and DKC is considered effective across various bifurcation angles. However, it remains unclear whether this standard approach is optimal for all patients.

Prediction of trumpet performance descriptors using machine learning

Acta Acustica
Based on a physical model of a trumpet’s functioning, the numerical continuation approach is used to construct the model’s bifurcation diagram, which depends on the instrument’s acoustic characteristics and the musician’s parameters.

Clinical Impact of Angiographic Complications Occurring During Percutaneous Coronary Interventions

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The clinical impact of different types of angiographic complications during elective PCIs remains largely unexplored. Aims To explore the incidence, management, and outcomes of angiographic complications by type and severity during non‐urgent, non‐CTO PCIs. Methods Clinical and procedural characteristics were prospectively collected

Spectroscopic Insights Into the Role of the Coverage of *CO and *H on Bifurcation of Ethylene and Ethanol Pathways in Carbon Dioxide Electroreduction

Carbon Energy, EarlyView.
Zhao et al. control the coverage of *CO or *H intermediates by introducing foreign metal into Cu nanoparticles. The increased *CO coverage on Ag‐doped and Zn‐doped Cu promotes the generation of multi‐carbon products while the increased *H coverage of Co‐doped and Pd‐doped Cu enhances the selectivity of oxygenates. ABSTRACT As key reaction intermediates

Analysis of Bifurcation Characteristics of Fractional‐Order Direct Drive Permanent Magnet Synchronous Generator

Energy Science & Engineering
In this study, we establish a fractional‐order direct drive permanent magnet synchronous wind turbines (DPMSG) model defined by Caputo based on the fractional calculus theory to overcome the singularity and limitations of integer‐order DPMSG models.
