Techno-economic comparison of operational aspects for direct drive and gearbox-driven wind turbines [PDF]
, 2010 The majority of wind turbines currently in operation have the conventional Danish concept design-that is, the three-bladed rotor of such turbines is indirectly coupled with an electrical generator via a gearbox.

Digital‐Twin‐Enabled, Time‐Aware Anomaly Detection for Industrial Cyber‐Physical Systems
Digital Twins and Applications, Volume 3, Issue 1, January/December 2026.The graphical abstract (Graphical Abstract figure) summarises the proposed pipeline: multivariate ICS data streams are windowed and normalised, fed into a temporal LSTM–DNN encoder and per‐sensor operating‐envelope learner, combined via calibrated fusion and finally surfaced through an operator‐facing digital twin that provides event timelines, top ...

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.

Reliability modelling of uninterruptible power supply using probability tree method [PDF]
, 2006 The unreliability of public power lines have led to the need of uninterruptible power supply (UPS). Utility power failures will cause unacceptably high risk to the profitability, existence and growth of the vital aspect of business that depends heavily ...

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 Safety‐Aware Framework for Offshore Wind Turbine Maintenance
Wind Energy, Volume 28, Issue 12, December 2025.ABSTRACT In this paper, we suggest a framework for determining the best operation and maintenance strategies for offshore wind turbines. The framework takes into account both quantitative and qualitative data gathered from the wind turbines. The proposed framework consists of a simulation‐optimization approach for designing, planning, and scheduling ...
