Artificial Neural Network Based SVC Switching At Distribution System for Minimal Injected Harmonics
Abstract: Electrical distribution system grieves from various problems like reactive power burden, unbalanced loading, voltage regulation and harmonic distortion. However DSTATCOMS are ideal solutions for such systems, they are not popular because of the cost and complexity of control involved. Phase wise balanced reactive power compensations are essential for fast changing loads needing dynamic power factor correcting devices leading to terminal voltage stabilization. Static Var Compensators (SVCs) remain ideal choice for …

Power Swing Detection and Out-of-Step Prediction Using the Equal Area Criterion
Abstract: During the operating conditions, the modern interconnected power systems are more subjected sudden changes, such as faults, network changes due to line trip outs, and disconnection of a large load or of a generating plant. Such disturbances create power swing among the other generators which forces the remaining generators to adjust and settle to new stable conditions. In some cases, the swings are so large that some generators run out …

Condition Monitoring of a Round Bar with a Defect Using Vibration Analysis
Abstract: As an energy-saving and high-efficient stress relieving process, vibratory stress relief [VSR] influence of on fatigue life is still explicit and needs further investigation. Standard specimens are manufactured to study the VSR effects on 2014 T6 aluminum alloy fatigue behavior. Dynamic stresses generated during vibration are measured by strain gauge and the residual stresses with and without VSR are compared to validate the stress relieving effects. Eventually, fatigue tests are …

Research Paper on Design and Analysis of an Anti-roll Bar
Abstract: An anti-roll bar is a component of many automobile suspensions that aids in reducing body roll during fast cornering or over road irregularities. It connects opposite wheels (left/right) via short lever arms linked by a torsion spring. An anti-roll bar is part of an automobile suspension system which limits the body roll angle of the vehicles. It is a U-shaped metal bar that connects opposite wheels together through short lever …

Simulation of Differential Space Time Block Coding
Abstract: AbstractIn such a coherent system, the underlying assumption is that the channel does not change during one frame of data. Thus, it can also be interpreted as the frame length is chosen such that the path gain change during one frame is negligible. This is basically the quasi-static fading assumption that we have used so far. There is a bandwidth penalty due to the number of transmitted pilot symbols. Of …

Comparative Analysis of a Lie Detector using Support Vector Machine, Naive Bayes, and Random Forest Algorithm with Speech to Text Conversion
Abstract: Lie detection, additionally known as deception detection, uses questioning techniques to determine truth and falsehood in response. Physiological responses like vital sign, blood pressure, heartbeat, and respiratory rate are used to discriminate between truth and lie. Once we lie, our blood pressure goes up, our heart beats quicker, we have a tendency to breathe faster (and our breathing slows once the lie has been told), and changes occur in our …
