A Probability‐Aware AI Framework for Reliable Anti‐Jamming Communication

CAAI Transactions on Intelligence Technology, Volume 11, Issue 2, Page 349-366, April 2026.
ABSTRACT Adversarial jamming attacks have increased on communication systems, causing distortion and threatening transmissions. Typical attacks rely on traditional, well‐defined cryptographic protocols and frequency‐hopping techniques. Nevertheless, these techniques become vulnerable when facing intelligent jammers.

Lifetime Characteristics Analysis and Reliability Evaluation of Support Capacitors for Traction Converters Under Electrothermal Coupled Stress

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
In this paper, we introduce a systematic evaluation framework for the remaining service life and reliability of DC‐link capacitors in railway traction systems. By refining traditional assessment techniques with an electrothermal‐coupled degradation model and utilising accelerated ageing data from high‐mileage components, our approach offers a robust ...

Non‐Isolated‐Isolated Hybrid Cascaded Multilevel Converter Based on an Extended Space Vector Pulse Width Modulation Strategy for Traction Drive Systems

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
ABSTRACT This paper proposes a non‐isolated‐isolated hybrid cascaded multilevel converter (NI–IHCMC) based on an extended space vector pulse width modulation (SVPWM) strategy for traction drive systems. Topology optimization and modulation constraints are adopted to eliminate the short‐circuit risks of the proposed design. The proposed topology retains

Identification of Critical Machine in Textile Industry Using Reliability‐Centred Maintenance and Failure Mode and Effects Analysis—A Case Study of Bahir Dar Textile's Share Company

The Journal of Engineering, Volume 2026, Issue 1, January/December 2026.
The study aims to mitigate these risks through the implementation of a structured RCM policy. The findings indicate that the machines in the spinning section are the most critical in terms of their failure impact. Implementing the RCM methodology demonstrates significant economic benefits by reducing risk through a targeted FMEA approach.

Seismic Design Gaps and Link Innovations: Evaluating Gusset Connected Box and I‐Shaped Links in Multi‐Tiered EBFs

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study addresses a critical gap in seismic design codes by evaluating the nonlinear performance of multi‐tiered eccentrically braced frames (MT‐EBFs) and offering practical recommendations for future provisions. MT‐EBFs, an advanced variation of conventional EBFs, incorporate multiple tiers of links and braces within a single story, making them ...

Real Availability Index for Energy Hubs: A Novel Monte Carlo–Markov Hybrid Approach for Comprehensive Reliability and Economic Analysis Incorporating Dynamic Demand Profiles in High‐Rise Residential Buildings

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
This paper conducted a unique availability and economic analysis of two energy hubs (EHs) with different capacities (2 MW and 900 kW). The proposed EH supplies the electricity and heat requirements of a high‐rise residential complex in Tehran. A new index called real availability was introduced and implemented, integrating hourly demand profiles and ...

Markov‐Driven Reliability Improvement in Duplex and Triplex Standby Architectures With Variable Failure and Repair Rates

Journal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.
To enhance the reliability of industrial wireless sensor networks (IWSNs), this study develops a state‐based continuous‐time Markov model for duplex and triplex architectures equipped with warm and cold standby backup sensors. The proposed model explicitly defines the state space, transition structure, and failure–repair dynamics for one, two, and ...
