On-chip integration of bulk micromachined three-dimensional Si/C/CNT@TiC micro-supercapacitors for alternating current line filtering

A novel fabrication strategy for the realization of a bulk micromachined 3D Si/C/CNT@TiC micro-supercapacitor is experimentally demonstrated.

IoT based Controlling of Power Grid

An electric network, electric grid, or electricity network is an integrated electricity supply network for producers to consumers. It consists of electricity producing stations. The main objective of this study is to monitor the electricity grid system process, disclose this system at a dangerous level, monitor the current line, and reduce conventional systems expenses. From anywhere on the Internet, we can monitor. We can do it also if a system is enabled or disabled. It uses an electrical microcontroller to monitor a single-phase electrical device using Arduino to read sensor voltage and current and then communicate measured data via a new Android application for wireless monitoring. It enables the monitoring of several basic power quality parameters of basic voltage. The technology also determines the line frequency and power factor.

SOLUTION OF THE PROBLEM OF FREE FLOW OF ROUGH TWO-DIMENSIONAL WATER FLOW WHEN FLOWING OUT OF A PRESSURE-FREE PIPE

The authors improved the solution of the problem of free spreading of two-dimensional in terms of turbulent potential uniform flows obtained by I.A. Sherenkov. To obtain an analytical solution, the concept of a general flow is used. The conjugation of the solution in the physical plane and in the plane of the velocity hodograph (virtual plane) is used. This made it possible to determine the coordinates of the points of the extreme current line and determine the current parameters leading to an unambiguous analytical solution of the flow geometry.

Khusro’s War of Revenge

The circumstances leading to war are enumerated—(1) gathering crises in the Balkans, Italy, and Armenia, and (2) Persian dissatisfaction with the current line of the frontier in the west. The November 602 coup of Phocas and execution of the Emperor Maurice, who had restored Khusro II to the Sasanian throne in 591, provided Khusro with a perfect pretext for going to war. The focus is then on Persian strategy. The main offensive thrusts alternated between the Mesopotamian and Armenian theatres of war in a first phase (603–5) which saw the outer defences of the Roman Empire breached. After a year’s pause, the offensive was renewed on a larger scale, simultaneous pushes being made in both theatres of war from 607, which brought Persian armies to the inner line of Roman defence on the Euphrates in 610.

Preventive aspect of ayurveda and yoga towards newly emerging disease COVID-19

The ongoing coronavirus pandemic is caused by severe acute respiratory syndrome coronavirus 2 (SARS CoV 2) and unique in various facets. The earlier experience from the past severe acute respiratory syndrome (SARS) epidemics seem to be insufficient and there is need for better strategies in public health and medical care. Ayurved & Yog are well known for their preventive and therapeutic aspect, but not getting utilized properly for prevention of Covid 19 crisis which may also be helpful as supportive therapy along with current line of management. This paper is aimed at unrevealing the role of Ayurved and Yoga guidelines established by Department of AYUSH for prevention from SARS-CoV-2 by providing help to improving the quality of supportive/prophylactic therapy in relation with their immunity.

Chemically Roughened, Sputtered Au Films with Trace-Loaded Manganese Oxide for both On-Chip and Off-Chip High Frequency Supercapacitors

High frequency supercapacitors (HFSCs) are promising in alternating current line filtering and adaptable storage of high-frequency pulse electrical energy. Herein, we report a facile yet integrated-circuit-compatible fabrication of HFSC electrodes by combining chemical roughening of the sputtered metal (Au) films and in situ trace loading of a pseudocapacitive material (MnOx). The developed electrode fabrication route is versatile for different substrates, and is described with the application paradigms of both on-chip (with Si/SiO2 substrate) and off-chip (without Si/SiO2 substrate, with Ti substrate as an example in this study) HFSCs. With Au/MnOx films on Si/SiO2 substrates as the working electrodes, the derived on-chip HFSC displayed satisfactory performance in high frequency applications (i.e., an areal capacitance of 131.7 µF cm−2, a phase angle of −78°, and a RC time constant of 0.27 ms, at 120 Hz).
