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 ...

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 ...
