Keywords: Wind turbine Fault prognosis Fault detection Pitch system ANFIS Neuro-fuzzy A-priori knowledge a b s t r a c t The fast growing wind industry has shown a need for more sophisticated fault prognosis analysis in the critical and high value components of a wind turbine (WT). Current WT studies focus on improving their reliability and reducing the cost of energy, particularly when WTs are...

Epidermal growth factor (EGF) 1 belongs to a family of structurally related growth factors which all exert their action by binding to the epidermal growth factor receptor (Carpenter & Wahl, 1991). Many tumor cells express this receptor, and also secrete members of this family of EGF-like molecules, thus creating the possibility of an autocrine growth factor cycle. In particular, the role of tra...

This talk deals with Android’s bytecode analysis. The Android system is now widespread, and lots of applications are developed each days. These applications are mostly written in Java, though it is possible to do calls to binaries or shared libraries. To be executed on the DVM the Java source code is translated into Java bytecode (.class files) and then a tool named ‘dx’ is used to convert it i...

Abrasive wear is defined wear due to hard particles or hard protuberances forced againts and moving along a solid surface. This defination encompasses several different mechanisms by which material removal occoures. The five types of wear are abrasive, adhesive, erosion, fatigue and fretting. The abrasive wear of polymeric materials is the interest and the subject of quite number of literature....

Neomycin, an aminoglycoside, is use at farm level for Escherichia coli treatment of piglets postweaning diarrhea, with 40% of unsuccessfully treatment due to the antimicrobial resistance. To overcome this situation, veterinarians use colistin also call polymyxin E, but this antibiotic is not homologated in Canada, even if it seems to be effective against E.coli. The described resistance to poly...

General-acid catalysis of the reaction of methoxyamine with phenyl acetate by the proton, carboxylic acids, and ammonium ions follows a nonlinear Bransted curve. This curve agrees quantitatively with the behavior expected for the enforced preassociation mechanism of catalysis that was predicted for this reaction. The stronger acids, including the proton, follow a Bransted slope of a = 0.16 that...

We present an algorithmic classification of drainage networks on Mars. Altogether, 368 drainage networks were computationally extracted using MOLA topographical data from various martian locations covering 16 major geological units. The classification is quantitative and objective, as it is based on a numerical description of drainage networks. Applying a clustering algorithm to our dataset, we...

Martian terrains are represented as a series of drainage basins, regardless of the historical presence or absence of actual fluid flow. A statistical analysis of each drainage network, computationally extracted from an underlying topography based on the MOLA data, yields a network descriptor, a compact, numerical characterization of a network. These descriptors are used to compare different mar...
