Mechanism of Intensive Gas and Fluid Mixture in the Process of Vibroturbulization and Its Technological Applications
Abstract: Previously conducted experimental studies have established that in a certain narrow frequency range and upon reaching a certain value of the amplitude of water oscillations in a sealed vessel with above-water air shell, subjected to vertical vibration, a resonant phenomenon occurs, called “vibroturbulization”, leading to intensive mixing of media of different density. The studies carried out were purely experimental in nature and could not reveal the physicochemical mechanism of occurrence, …

The Impact of MEMS on the Internet of Things (IoT)
Abstract: Our daily lives, workdays, and connections with the external world are all being impacted by theInternet of Things (IoT). Micro Electro-Mechanical Systems (MEMS) are tiny, economical, andpretty accurate sensors that can measure a variety of physical variables, including temperature,pressure, humidity, acceleration, and more. They are a fundamental enabler of this technology. Inthis article, we examine the effects of MEMS on the IoT and the ways in which these incrediblysmall sensors …

Phase Noise Reduction in WLAN by Applying Wavelet Packet Multiplexing
Abstract: The IEEE 802.11 standards for wireless Local Area Networks (LANs) commercialized as Wi-Fi are deployed in office and home environments. These systems provide data rates up to 1300 Mbps at 5 GHz and 400 Mbps at 2.4 GHz with physical layer based on OFDM and MIMOOFDM. Traditionally, multiplexing in OFDM is realized using static orthogonal waveforms derived from Fourier transforms. The decoding of the data at receiver is based on …

A Circuit Approach for CMOS VLSI Circuit Leakage Power Reduction
Abstract: Despite the fact that scaling CMOS technology boosted speed, leakage currents always remained an issue. The issue has gotten worse as the scaling has gone into the UDSM (ultra-deep-submicron) range. In order for the circuit to function effectively, these unwanted leakage currents must be reduced to a minimum. It is challenging to create these leakage-free nano-scale CMOS circuits. In this work, the issue of leakage power is addressed, which occurs …

Overcurrent Elimination and Current Ripple Reduction in Multi- Motor Systems Fed by Reduced Switch-Count VSI Using Advanced Scheme for High-Performance Drive Applications
Abstract: This paper proposed a novel control approach for overcurrent removal and reduction of current ripple for multi-motor systems powered by a Voltage Source Inverter (VSI) with a reduced switch-count. This approach significantly enhances the regulation of armature current with improved performance of the drive while improving the hardware utilization of the inverter. Simulation and analysis showed the capability of the scheme to improve power quality and improve system reliability, making …
