Journal of Prosthodontics, Volume 35, Issue 3, Page 407-413, March 2026.Abstract This technique describes a scanner‐agnostic digital workflow for generating dynamic mandibular motion from static virtual interocclusal records using a custom artificial intelligence (AI) algorithm and user interface. Virtual records of mandibular positions, including maximum intercuspation, protrusion, and lateral excursions, were captured ...

Bionic Optimization and Aerodynamic Performance Analysis of High-speed Train Pantograph
Journal of Applied Science and EngineeringThe aerodynamic drag of a high-speed train has a significant impact on its energy consumption. At high speeds, the pantograph is one of the primary sources of aerodynamic drag for the train.

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.This study evaluates the potential of piezoelectric vibration energy harvesting to power IoT nodes for real‐time health monitoring of the Mongolian railway. Triaxial vibration data were collected at 500 Hz over a 400 km freight route under loaded and unloaded conditions using a custom ESP32‐S3 + MPU9250 system, and dominant frequencies were extracted ...

Computer simulation of pantograph delay differential equations
Thermal Science, 2021 Ritz method is widely used in variational theory to search for an approximate solution. This paper suggests a Ritz-like method for integral equations with an emphasis of pantograph delay equations. The unknown parameters involved in the trial solution can be determined by balancing the fundamental terms.

Exact and Approximate Solutions for Some Classes of the Inhomogeneous Pantograph Equation
Axioms, 2023 The standard pantograph delay equation (SPDDE) is one of the famous delay models. This standard model is basically homogeneous in nature and it has been extensively studied in the literature. However, the studies on the general inhomogeneous form of such

Journal of Mathematics, Volume 2026, Issue 1, 2026.In this work, we present some analytical and topological framework for fractional nonlinear systems on compact‐open Banach spaces. By using the locally compact property of these spaces, the continuity and compactness of nonlinear operators are rigorously established.
