Power Quality Issues and Mitigation Strategies: A Review
Abstract: AbstractTo protect the power system recognition and arrangement of voltage (V) and current (I) issues are essential tasks. Most power quality (PQ) disturbances are unstable and ephemeral; the call for recognition and arrangement of voltages and current is proved. There are some intelligent system technologies which have dominance regarding fault analysis by using wavelet transform (WT), expert systems and artificial neural networks. As signals are classified in six classes: five …

Analysis of Speech Using Different Methods
Abstract: In speech analysis, the voiced-unvoiced decision is usually performed in extracting the information from the speech signals. In this paper, two methods are performed to separate the voiced and unvoiced parts of the speech signals. These are zero-crossing rate (ZCR) and energy. In here, we evaluated the results by dividing the speech sample into some segments and used the zero-crossing rate and energy calculations to separate the voiced and unvoiced …

Localization Based Beamforming Approach to Audio Source Separation from Binaural Mixtures
Abstract: This paper presents an approach of localization on the basis of audio source separation from binaural mixtures with adaptive beamforming. A new source localization technique is proposed to spatially localize the sources with two degrees of freedom (azimuth and elevation). We used a head related transfer function to synthesize the binaural mixture that introduces the interaural differences to the source signals. The interaural cues are technically employed to estimate the …

Suspension System with Combined Leaf and Helical Spring: A Review
Abstract: A good suspension system of any automobile vehicle must have minimum deflection, minimum weight, low maintenance and low operating cost with some other fine properties. Springs are major element of any suspension system and first line of its defense. If the suspension springs are rigid enough, they will not absorb road shocks efficiently, and if they are more flexible, then they will keep vibrating for a longer time even after …

Heterogeneous vs. Homogeneous Catalysis: Comparative Insights and Breakthroughs
Abstract: Catalysis, a pivotal process in chemical reactions, can be classified into two main types: heterogeneous and homogeneous catalysis. This comparative analysis delves into the distinctions, advantages, and breakthroughs in both domains. Heterogeneous catalysis, involving catalysts in a different phase than the reactants, is characterized by ease of separation and catalyst recovery, making it industrially favorable. Conversely, homogeneous catalysis, where catalysts and reactants share the same phase, offers superior selectivity and …
