Output feedback stabilization of nonlinear switched systems via incomplete information

This paper addresses the challenging problem of output feedback finite-time stabilization for a class of nonlinear switched systems subject to digital signal constraints. Existing methods typically handle state observation, signal sampling, and quantization separately, leading to...

Lignin-Assisted Construction of Coal-Tar-Pitch-Derived N/S Co-doped Porous Carbon for Boosted Zinc Ion Storage

Abstract Zinc ion capacitors (ZICs) based on a carbon cathode represent new generation energy storage system, owing to outstanding safety, economic viability, and ecological sustainability. However, carbon-based cathodes suffer from limited charge storage. Thus, it is urgent to d...

Field-Validated Hyperbolic Model Predicts Load Displacement of Untested Grouted Railway Piles

ABSTRACT Current design codes for grouted piles focus exclusively on bearing capacity improvements (β factors) and lack reliable methods for displacement prediction, creating significant risks for settlement-sensitive railway infrastructure. To address this gap, this study propos...

Dynamic Scheduling of a Photovoltaic–Storage Office Building with Heating, Ventilation, and Air-Conditioning and Electric-Vehicle Flexibility

High photovoltaic (PV) penetration can create hourly mismatches among office-building demand, renewable generation, electricity prices, and grid carbon intensity. This study develops a reproducible, deterministic, time-coupled day-ahead mixed-integer linear programming model for...

Dynamic Modeling and Self-Tuning Fuzzy Skyhook Control of a Metro Vehicle with a Flexible Carbody and Semi-Active Suspension

Lightweight metro carbodies may exhibit elastic modes within ride-comfort-relevant frequency bands, limiting semi-active suspension controllers tuned offline for nominal conditions. This study proposes a skyhook-based parameter self-tuning fuzzy control (PSTFC) strategy for later...

XrayCLIP: A VLM-Based X-Ray Security Inspection System for Railway Safety

Railway safety is an important component of public security. Ensuring the safety of high-speed rail systems and passengers is also crucial for railway transportation enterprises. The performance of X-ray security inspection systems is one of the key factors in improving intellige...

Interfacial Mechanisms and Shear-Key Improvement for an Assembled Integral Multi-Ribbed Composite Floor System

A novel assembled integral multi-ribbed composite floor system consisting of precast panels and a cast in situ topping has previously been validated through full-scale one-way and two-way slab experiments. Although the global load capacity of the system was initially verified, th...

Capacitance-Based Characterization of Air-Void Distribution in Asphalt Mixtures Using a Saturated Reference Field

Air-void distribution is an important internal characteristic of asphalt mixtures, as it affects compaction quality, moisture susceptibility, permeability, and long-term pavement durability. Conventional air-void testing methods generally provide only an average volumetric parame...

A Multi-Source Cross-Domain Data Fusion Framework for Ordinal Health-State Assessment: A Reproducible Surrogate Benchmark Motivated by Hydrogen-Cooled Turbogenerators

Real-world fault data for hydrogen-cooled turbogenerators are scarce and largely proprietary, which hinders data-driven health assessment aligned with severity standards. This paper proposes a standards-aligned, multi-source ordinal fusion framework and demonstrates it, as a proo...
