POWER AMPLIFIER- introduction to power amplifier.pptxDrVikasMahor
A power amplifier is the last amplifier stage that delivers power to the load. Power amplifiers are classified based on the proportion of the input cycle during which the amplifying device conducts current. Class A amplifiers conduct over the entire input cycle but have low efficiency. Class B amplifiers only amplify half of the cycle, improving efficiency but introducing distortion. Class AB is a compromise with better linearity than B. Class C has very high efficiency but is used for RF where distortion is controlled by a tuned load. Class D amplifiers use pulse-width modulation for very high efficiency.

final thesis pptReductions of leakage and ground bounce noise in.pptDrVikasMahor
This document discusses a stacking power gating technique to reduce leakage current and ground bounce noise in high performance circuits. The stacking technique uses two sleep transistors connected in series to virtually ground a circuit block in sleep mode. This reduces leakage by raising the intermediate node voltage. Ground bounce is reduced by controlling the intermediate node voltage and turning on the second transistor in the linear region. Simulation results show the stacking technique reduces leakage by 81.71% and ground bounce by 90.39% compared to conventional power gating. However, it increases wakeup latency due to the intermediate node control.

The 8259A is an interrupt controller that manages interrupt requests from peripheral devices connected to a microprocessor. It has 8 interrupt request lines that accept signals from devices. The 8259A prioritizes the interrupt requests, masks some if needed, and issues an interrupt signal to the CPU. It then provides the CPU with the address of the interrupt service routine for the highest priority active interrupt by placing the address bytes on the data bus over 3 interrupt acknowledge pulses from the CPU. This allows efficient interrupt-driven processing of device requests.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Rainfall intensity duration frequency curve statistical analysis and modeling...bijceesjournal
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

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.
