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.

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 ...

A Systematic AI‐Based Paradigm for Classifying Hybrid Electric Vehicle Spare Parts Using Their Price and Demand

Journal of Engineering, Volume 2026, Issue 1, 2026.
With the rapid growth of the hybrid electric vehicle (HEV) market, stakeholders must refine after‐sales logistics, particularly spare parts (SPs) provisioning. Adequate forecasting of demand and pricing underpins these efforts. This paper presents a feedforward artificial neural network (FF‐ANN) that, drawing on 15 predictor variables, assigns each SP ...
