Research ArticleOpen accessEvery word in the titleMinimization of Load Oscillations in Travelling Mechanisms of CranesKamal KhandakjiThe paper presents an analysis of suspended load (cargo) oscillations in traveling mechanisms of cranes. A special control algorithm has been developed in order to get minimum cargo oscillations in minimum transient time. Mathematical model simulating the effect of the suggested control algorithm on cargo oscillations has been developed. Two power electronic circuits applicable for AC drives with three-phase induction … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,672 accessesView PDFCite

In the present paper, hysteresis, resonant oscillations and bifurcation mode of a system modeled by a forced modified Van der Pol-Duffing oscillator are considered. The plasma oscillations are considered and are described by a nonlinear differential equation. By using the … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 23 Oct 2017 · 7,898 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFour Dimensional (4-D) BioChemInfoPhysics Models of Cardiac Cellular and Sub-Cellular Vibrations (Oscillations)Kang Cheng, Chang-Hua ZouProblem statement: Cardiovascular Diseases (CVD) continued to be the leading cause of death. Failure or abnormal cardiac cellular or sub-cellular vibrations (oscillations) could lead failure or abnormal heart beats that could cause CVD. Understanding the mechanisms of the vibrations (oscillations) could help to prevent or to treat the diseases. Scientists have studied the mechanisms for more than 100 years. To … …OnLine Journal of Biological Sciences, Vol. 9, Issue 2 · 15 Jun 2009 · 7,057 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReservoir Oscillations with Through FlowA.A. KhanThe two-reservoir problem with through flow is a common feature in wastewater treatment plants. The start of the through flow may cause water surface oscillations in the reservoirs and velocity variations in the connecting pipe during the initial unsteady phase that may adversely affect the operation and under certain conditions may cause overtopping of the upstream reservoir. The classical solution … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 7,030 accessesView PDFCite

Research ArticleOpen accessIn the keywordsA TIME-DELAY CASCADING NEURAL NETWORK ARCHITECTURE FOR MODELING TIME-DEPENDENT PREDICTOR IN ONSET PREDICTIONAgus Buono, Imas Sukaesih Sitanggang, Mushthofa, Aziz KustiyoThe occurrence of rain before the real start of a rainy season often mislead farmers into thinking that rainy season has started and suggesting them to start planting immediately. In reality, rainy season has not started yet, causing the already-planted rice seed to experience dehydration. Therefore, a model that can predict the onset of rainy season is required, so that … …Journal of Computer Science, Vol. 10, Issue 6 · 29 Jan 2014 · 6,647 accessesView PDFCite
