Induction motors are subject to different faults which, if undetected, may lead to serious machine failures. From the scrupulous review of related works, it is observed that neurofuzzy and neural network (NN)-based fault-detection schemes are performed well for large machines and they are not only expensive but also complex. In this paper, the authors developed the radial-basis- functionmultilayer-perceptron cascade-connection NN-based fault-detection scheme for the small and medium sizes of three-phase induction motors. Stator winding interturn short, rotor eccentricity, and both faults simultaneously are selected for demonstration. Simple statistical parameters of stator current are considered as input features. Principal component analysis is used to select suitable inputs to the network. Experimental results are included to show the ability of the proposed classifier for detecting faults. Moreover, the network is tested for the robustness to the uniform and Gaussian noises. Having good classification accuracy with enough robustness to noises, the proposed classifier is suitable for the real-world applications. © 2010 IEEE. Source

The exact solutions of the field equations in respect of LRS Bianchi type-I space time filled with perfect fluid in the framework of f(R, T) gravity (Harko et al., arXiv:1104.2669v2 [gr-qc], 2011) are derived. The physical behavior of the model is studied. In fact, the possibility of reconstruction of the LRS Bianchi type-I cosmology with an appropriate choice of a function f(T) has been proved in f(R, T) gravity. © 2011 Springer Science+Business Media B.V.

The Chicxulub asteroid impact (Mexico) and the eruption of the massive Deccan volcanic province (India) are two proposed causes of the end-Cretaceous mass extinction, which includes the demise of nonavian dinosaurs. Despite widespread acceptance of the impact hypothesis, the lack of a high-resolution eruption timeline for the Deccan basalts has prevented full assessment of their relationship to the mass extinction. Here we apply uranium-lead (U-Pb) zircon geochronology to Deccan rocks and show that the main phase of eruptions initiated ∼250,000 years before the Cretaceous-Paleogene boundary and that >1.1 million cubic kilometers of basalt erupted in ∼750,000 years. Our results are consistent with the hypothesis that the Deccan Traps contributed to the latest Cretaceous environmental change and biologic turnover that culminated in the marine and terrestrial mass extinctions.

Expert Review of Anti-Infective Therapy | Year: 2012

Antibiotic resistance is documented to be a serious problem that affects the choice of appropriate antibiotic therapy and increases the probability of unfavorable infection outcome. One of the proposed methods to cope with multidrug-resistant (MDR) bacteria is the use of alternative antibacterial treatments, which include natural antimicrobial substances such as plant essential oils (EOs). The aim of the present article is to review published studies on the activity of EOs and their constituents against MDR bacteria and to formulate perspectives for the future. In general, published studies indicate that EOs can be used as effective antiseptics against many species, including MDR bacteria, such as methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, resistant isolates of Pseudomonas aeruginosa, Klebsiella pneumoniae and others; certain EOs may potentiate the effectiveness of antibiotics against MDR bacteria; EOs can be synergistic with bacteriophages; and polymeric nanoparticles can be used for delivery of EOs and enhancement of their activity at the site of infection. © 2012 2012 Expert Reviews Ltd.

Tin dioxide (SnO2) material changes its properties depending on the ambient gas which can be utilized as gas sensing materials. Usually changes in electrical resistance/conductance in response to environmental gases are monitored. SnO2 and double layer (SnO2/Al 2O3) sensors have been prepared by screen-printing technique on glass substrate. The sensors were used for different concentration (ppm) of CO2 gas investigation at different temperature. The sensing response (sensitivity) of SnO2/Al2O3 double layer sensor was found to be higher, compared with pure SnO2 sensor. The average grain size of SnO2 was determined from XRD pattern and found to be 120.7 nm. The activation energy (Ea) of first order reaction (n =1) for SnO2 has been found to be 72.06 kJ/g-mol from endo DDTA and 325.95 kJ/g-mol from exo DDTA. The microstructure of SnO 2 has been studied from SEM analysis. The oxygen ions adsorb onto the surface of material removes electrons from the bulk and create a potential barrier that limits electron movement and resistivity. When exposed to an oxidizing gas such as CO2 then it is chemisorbed on bridging oxygen atoms with the formation of a surface carbonate, subsequently increasing the barrier height and resistivity.
