Research ArticleOpen accessIn the keywordsElectromagnetic Interference Mitigation for Inverter fed AC DrivesC. Karthikeyan, K. DuraiswamyProblem statement: In switched mode PWM inverter EMI noise occurs during high (dv/dt) transient period. This EMI noise is mitigated using Active Common mode EMI filter in front of the source. Approach: This study proposes a new active common mode Electromagnetic Interference (EMI) filter for switched mode PWM Inverter applications. The proposed filter is based on current sensing and compensation … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 12 Sep 2011 · 7,309 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEchocardiographic Pulmonary to Left Atrial Ratio in Dogs (ePLAR): A Differential Marker of Pre- and Postcapillary Pulmonary HypertensionDmitrij Oleynikov, Ma YiPulmonary Hypertension (PH) in dogs is a complicated syndrome that could be primary, due to idiopathic or genetic causes, or secondary due to pulmonary disease, pulmonary thromboembolism, heartworm disease, heart failure. Due to the inability of the routine use of right heart catheterization in veterinary patients, there is a lack of differential criteria between PH forms. This study was performed … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 1 · 17 Feb 2022 · 6,791 accessesView PDF Cite

Research ArticleOpen accessIn the abstractON FINITE DIFFERENCES ON A STRING PROBLEMJ. M. Mango, C. Eryenyu, S. E. RugeihyamuThis study presents an analysis of a one-Dimensional (1D) time dependent wave equation from a vibrating guitar string. We consider the transverse displacement of a plucked guitar string and the subsequent vibration motion. Guitars are known for production of great sound in form of music. An ordinary string stretched between two points and then plucked does not produce quality sound … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 22 Feb 2014 · 6,971 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGradient Descent Learning for Utility Current Compensation using Active Regenerative PWM FilterR. Balamurugan, G. GurusamyProblem statement: Harmonic analysis is a primary matter of power quality assessment. Its main intention is to check the utility whether it is delivering the loads without any deviations in voltages and currents. The problem is due to proliferation of Electronic converters and power electronics which gave birth to numerous new applications, offering unmatched comfort to the customers. Approach: Harmonics … …Journal of Computer Science, Vol. 7, Issue 12 · 14 Oct 2011 · 6,545 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effect of Omega-3 Fatty Acids on Nerve Conduction Velocity (NCV) and F-wave Latency in Patients with Diabetic polyneuropathyNaser Zangiabadi, Mohamad N. Ahrari, Nouzar NakhaeeDiabetes mellitus with the prevalence rate of 8.9-12.3% in human population, ultimately leads to the peripheral nervous system involvement in many patients. It causes various types of polyneuropathies, which may manifest abnormalities such as impaired nerve conduction velocity (NCV) and prolonged F-wave latency. The aim of this study was to investigate the effect of omega-3 fatty acids on NCV and … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 1 · 31 Mar 2007 · 9,272 accessesView PDF Cite
