continuity equation and relaxation time

Raviraj solanki

1. The continuity equation states that the time rate of change of charge within a volume must equal the net outward current flow through the closed surface. 2. When charge is introduced into a conductor or dielectric, the volume charge density will decay over time according to an exponential decay function. 3. The relaxation time is the time constant of this exponential decay function, and represents the time needed for the initial charge density to reduce to 37% of its initial value. Relaxation times are short for good conductors but long for good dielectrics.

Parallel Inverter

Smit Shah

This document discusses a parallel inverter circuit. It contains two SCRs that act as the main load carrying components. Diodes allow reactive power from the load to be fed back to the DC supply. When SCR1 conducts, the load voltage is positive and equal to the input voltage. When SCR1 turns off, the energy stored in the capacitor is fed back to the load through the transformer. This reverses the load voltage polarity. The parallel inverter has advantages over series and bridge inverters in that the load voltage is not dependent on the load, only two SCRs are needed, and commutation components do not carry the full load current.

Real-Time Monitoring of Industrial Environmental Temperature using LabVIEW

IJERA Editor

Graphical System Design applications are the fastest spreading one in the field of industrial environment. Over the decades monitoring of physical parameters in the industrial environment is made easy with various sensors. Several softwares are used to monitor those physical parameters. The objective of the work is to monitor the environmental temperature. The sensors that are used to measure the physical parameters tend to give electrical output either in form of Voltage or Current. In this paper current output is preferred for temperature conversions rather than the voltage output as they tend to drop over the transmission line. The current output of Temperature/Humidity sensor (THD Series) is converted into temperature in degree Celsius. The Real-Time environmental parameters are acquired from Autonics Temperature/Humidity sensor using NI Compact DAQ 9174(cDAQ). A Graphical approach is developed in LabVIEW platform to monitor the environmental temperature with the help of a PC.

5V_DC POWER Supply

Ashish Sadavarti

Most electronic circuits require a DC power supply, which is obtained by converting the AC mains supply to DC using a rectifier. There are different types of rectifiers including half wave, full wave, and bridge rectifiers that convert the alternating current to direct current by only allowing current to flow in one direction. A specification sheet provides details on linear voltage regulators like the 78XX series that are commonly used to provide stable DC voltages for circuits.

BUBBLESORT

Ashish Sadavarti

The document describes the bubble sort algorithm. Bubble sort works by comparing adjacent elements and swapping them into ascending order. This process is repeated, with each iteration bubbling the largest remaining element to its correct position. The algorithm has an outer loop that repeats the bubbling process N-1 times to fully sort an array of N elements. Each iteration reduces the number of comparisons needed by bubbling one element into place. Though simple, bubble sort is not very efficient for large arrays due to its quadratic time complexity.

Derivatives & Risk Management

Ashish Sadavarti

Mr. Sadavarti presented on the short call option strategy. A call option gives the holder the right to buy the underlying asset at a set price. For a short call option strategy, the seller of the call option expects the underlying price to fall. As an example, Mr. Nelson sold a call option on Nifty with a strike price of Rs. 2600 and received a premium of Rs. 154. If the Nifty closes at or below Rs. 2600 at expiration, Mr. Nelson keeps the full premium. His maximum profit is Rs. 154 with unlimited risk if the Nifty rises above the strike price plus the premium received.

nooriasukmaningtyas

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT

jpsjournal1

The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been referred to as the "New Great Game." This research centres on the power struggle, considering geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil politics, and conventional and nontraditional security are all explored and explained by the researcher. Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role in Central Asia. This study adheres to the empirical epistemological method and has taken care of objectivity. This study analyze primary and secondary research documents critically to elaborate role of china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade, pipeline politics, and winning states, according to this study, thanks to important instruments like the Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study, China is seeing significant success in commerce, pipeline politics, and gaining influence on other governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai Cooperation Organisation and the Belt and Road Economic Initiative.

Low power architecture of logic gates using adiabatic techniques

nooriasukmaningtyas

The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.

Advanced control scheme of doubly fed induction generator for wind turbine us...

IJECEIAES

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
