In this paper, a novel fault diagnosis method for variable frequency drive (VFD)-fed induction motors is proposed using Wavelet Packet Decomposition (WPD) and greedy-gradient max-cut (GGMC) learning algorithm.The proposed method is developed using experimental stator current data in the lab for two 0.25 HP induction motors fed by a VFD, subjected t
The proposed method for calculation of the energy value of culture media is based on stoichiometric properties of biological oxidative reactions in the cell and allows for assessment of the nutritional value of organic substrates with consideration of their elemental composition.Three organogen elements (carbon, hydrogen blueberry bubblicious and o
This study explored the potential contribution of Orx1R within vlPAG to the learning and memory of animals with chronic migraine-like pain.Migraine was induced by repeated i.p.administration of nitroglycerin (5 mg/kg).Passive avoidance adeptness was evaluated in the shuttle box maze.The spatial memory performance was estimated using MWM tests.In th
The subject matter of this article is the dynamic characteristics of a composite propeller blade.Determination of the modes and frequencies of natural vibrations is necessary to predict the dangerous resonance modes of aircraft engines and to identify the most stressed local zones of the blade surface.The t4450 samsung goal of this study is to deve
