in this paper, in order to increase the efficiency, to reduce the cost and to prevent the failures of wind turbines, which lead to an extensive break down, a robust fault diagnosis system is proposed for v47/660kw wind turbine operated in manjil wind farm, gilan province, iran. according to the acquired data from iran wind turbine industry, common faults of the wind turbine such as sensor fault...

[1] Field work and topography analysis show that remnant, local areas of a low-relief landscape or erosion surfaces are geographically continuous across the southeastern Tibetan Plateau margin. We correlate these remnant surfaces as a paleolandscape that formed at low elevation. Remnants of this paleolandscape are preserved because incision of the fluvial system has been largely limited to majo...

One of the key issues in membrane technology is to avoid fouling which is formed on the membrane surface. To get over this trouble, the use of a patterned surface was suggested as a way to reduce fouling. In this report, both the experimental and numerical studies were performed with a prism patterned membrane system. In our experiments, we observe the local distribution of microbials; more fou...

[1] The morphology of the Mangala Fossa graben forming the source of the Mangala Valles implies that two episodes of graben subsidence took place, each induced by lateral dike intrusion from Arsia Mons. Quantitative modeling suggests that graben boundary faults breaching the cryosphere provided pathways for water release from an underlying aquifer at a peak rate of 10 m s . In the first event, ...

New high-resolution bathymetric data from Atlantis Massif and surrounding seafloor (30°N, Mid-Atlantic Ridge) records avolcanic extension associated with the formation of axial rift valley floor, following tectonic truncation an active corrugated oceanic detachment fault system. The truncated is tectonically uplifted by a high-angle valley-bounding normal fault, formed after westward migration ...

The performance of ion exchange (IX) resin for organics removal from wastewater was assessed using advanced characterisation techniques for varying doses of IX. Organic characterisation using liquid chromatography with a photodiode array (PDA) and fluorescence spectroscopy (Method A), and UV254, organic carbon and organic nitrogen detectors (Method B), was undertaken on wastewater before and af...

Dielectric interface would be formed on the electrode surface during the analysis or disposal of many phenolic compounds due to electro-polymerization. This could cause electrode passivation, also called electrode fouling, which is indicated by the continuously decaying current signal. This paper proposed a model based on the potential drop across the fouling layer, which is helpful for deep un...

Blooms of blue-green algae such as Microcystis aeruginosa in aquatic systems can result in substantial algal organic matter (AOM) entering downstream water treatment facilities. It has been demonstrated in a number of recent studies that AOM can cause severe fouling of low pressure membrane filtration systems [1, 2]. In this work the distribution of the foulant on a ceramic microfiltration memb...
