Audio De-noising using Adaptive Inertia Weight Particle Swarm Optimization Algorithm (AIW-PSO)
Abstract: There has been a lot of research in Audio de-noising so far but scope for improvement is always there. The motivation to use AIW-PSO algorithm as a possible alternative is to explore new ways to reduce global cost and to achieve better noise reduction performance. Particle swarm optimization is a heuristic stochastic evolutionary algorithm. However, standard PSO provides unbalanced exploration and exploitation. This paper presents a methodology to improve the …

Control System for Power Saving and Dual Mode Operation of the Escalator: A Microcontroller Approach
Abstract: An escalator is a moving flight of steps—a conveyor transportation device to haul public between floors of a building consisting of a motor-driven chain of steps to haul up and down on tracks. It allows the step treads to remain flat to earth surface. The establishment and operation of escalators requires large space and consumes substantial amount of power. The escalator used in public spaces runs idle wasting power, a …

Bearing Fault Diagnosis Using ANN and SVM with the Help of Wavelet Transform Based Features
Abstract: Many researchers use vibration signals as fault characteristics of any rotating bearing for fault detection and use various optimization techniques available for fault of bearing classification. The method of fault classification uses few neural network (NN) geometry and parameters necessary for the formulation. There is no derived formulation which can be used to select the optimal values for the network parameters. The parameters which are required to be calculated, impacts …

Implementation of Flexible Wearable Antenna
Abstract: This paper is to analyze a light weighted flexible antenna for modern communication system. The proposed antenna is compact in size, shows high directivity and large bandwidth. Polystyrene foam is used as a substrate because such antenna is bendable, wearable, cheap, requires less attention and has good features like low dielectric constant, low loss tangent and better efficiency. The parameters of antenna such as return loss, gain, bandwidth, radiation pattern …
