This paper presents a newly developed aero-servo-elastic platform for implementing smart rotor control and shows its effectiveness with aerodynamic loads on large-scale offshore wind turbines. The platform was built by improving the FAST/Aerodyn codes with the integration of an external deformable trailing edge flap controller in the Matlab/Simulink software. Smart rotor control was applied to ...

* Corresponding author. ** This work was sponsored by CAPES and SELPER (Brazil). Abstract – The simulation of one or more bands of a multispectral sensor by combination of other bands is a useful tool as an image processing technique. This work presents a simulation technique for the ETM+ panchromatic band based on linear combination of ETM+ multispectral bands. The simulation method takes into...

The quasi-synchronization for a class of general heterogeneous neural networks is explored by event-based impulsive control strategy. Compared with the traditional average interval (AII) method, instead, an event-triggered mechanism (ETM) employed to determine instants, in which case subjectivity selecting controlling sequence can be eliminated. In addition, considering fact that communication ...

In the paper, we describe development and implementation of reliable H∞filters for a class Networked Markov Jump Systems (NMJS) with random sensor failures that are triggered by events. The plant's nonlinear dynamic is approximated NMJS. Failures sensors described using stochastic variables. Event-Triggered Mechanism (ETM) introduced to NCS, which offers some positive points over other schemes....

This study concerned the assessment of changes in coastline Kavvayi beach and its nine islands a tropical coastal wetland using remote sensing (RS) data geographic information systems (GIS), as this sedimentary environment is still poorly characterized. The satellite used were from LANDSAT images (30 m spatial resolution) (MSS—volume 5, TM, ETM, ETM+ volume 6) for period last 25 years (1990 to ...

Sejak diperkenalkannya solar cell (PSC), konversi dayanya telah mencapai di atas 23% dalam waktu relatif singkat diiringi peningkatan publikasi ilmiah bidang ini. Penggunaan semikonduktor ZnO sebagai Elect...

Determining the productivity of forest sites through various classification techniques is important for making appropriate forest management decisions. Forest sites were classified using direct and indirect (site index) and remote sensing (Landsat 7 ETM and Quickbird satellite image) methods. In the direct method, forest site classifications were assigned according to edafic (soil properties), ...

Energy transition mineral and metals (ETM) are being widely discussed for their utility in combating climate change. However, contribution with respect to social environmental impact does not feature prominently contemporary debates. In this paper we present findings showing the extent which world's ETM projects will intersect Indigenous Peoples' Peasant lands – of people who under existing Uni...
