Wind Turbine Gearbox Anomaly Detection Based on Adaptive Threshold and Twin Support Vector Machines
IEEE transactions on energy conversion, 2021Data-driven condition monitoring reduces downtime of wind turbines and increases reliability. Wind turbine operation and maintenance (O&M) cost is a significant factor that calls for automated fault detection systems in wind turbines. In this manuscript,

AbstractObjectives To present unusual computed tomography (CT) findings concerning huge pneumatization of turbinates and paranasal sinuses in one patient. In current world literature the authors only found nine reports of pneumatization of inferior turbinates, which, therefore, must be considered an extremely rare anatomical finding.Study Design Case ...

Turbinate Hypertrophy: Turbinate Surgery
2021A 26-year-old female was referred to the ENT Department by her GP complaining about bilateral nasal blockage, notably worse in the course of occasional viral infections, constant clear nasal discharge and occasional sneezing. The patient had tried courses of intranasal steroids and oral antihistamines prescribed by her GP, which improved her nasal ...

Industrial gas turbines show performance characteristics that distinctly depend on ambient and operating conditions. They are not only influenced by site elevation, ambient temperature, and relative humidity, but also by the speed of the driven equipment,

Sliding Mode Control of PMSG Wind Turbine Based on Enhanced Exponential Reaching Law
IEEE transactions on industrial electronics (1982. Print), 2016This paper proposes a sliding-mode control (SMC)-based scheme for the variable-speed direct-driven wind energy conversion systems (WECS) equipped with a permanent magnet synchronous generator connected to the grid.

Normally, there are three pairs of nasal turbinates in the nasal cavity. Coronal computed tomographies of 253 cases of sinusitis were examined for the presence of additional turbinates and bilateral secondary middle turbinates were detected in two cases.

Thermodynamic Analysis of “Inter-Turbine” and “Intra-Turbine” Reheat for Marine Gas Turbines
Volume 5: Turbo Expo 2004, Parts A and B, 2004This paper presents thermodynamic analyses of two types of reheat combustion cycles in gas turbines and provides an evaluation of their usefulness in marine power and propulsion applications. Specifically, baseline cycles, using components of various technology levels, were compared to cycles with single-stage reheat (inter-turbine reheat), and ...
