Oscillation of a Second-Order Differential Equation as a Consequence of Iterative Monotonicities

The aim of this work is to provide an iterative process for generating new monotonic properties for positive solutions of the second-order delay differential equation y″(t)+p(t)y(τ(t))=0, which will lead to the improvement of known oscillatory criteria.

Anti-Jamming Algorithm Based on Stackelberg Game and Soft Actor-Critic

This paper studies a hybrid anti-jamming architecture using a Stackelberg game as its theoretical formulation in which a Soft Actor-Critic (SAC) agent selects a robustness radius and a power-control coefficient, while model-based power allocation and second-order cone programming...

Influence of FFF Substrate Material and 3D-Printed Surface Morphology on the Formation of Electrodeposited Copper Layers

Electrodeposition of metallic coatings represents a promising approach for extending the functional properties of additively manufactured polymer components. However, the resulting coating morphology may be influenced not only by the deposition conditions but also by the material...

Numerical analysis of seismic performance of deep strutted excavation-structure interaction in sandy soil

This research investigates numerically the seismic performance of deep-braced excavation in adjacent to 10-stories building in sandy soil. Non-linear time-history analysis using hardening soil model with small strain stiffness (HS-small) is performed using PLAXIS 2D. Numerical va...
