Simulation of the receiving antenna for detecting Jovian radio waves using 4Nec2 software.
To capture signals from Jupiter, a magnetic self-resonant large circular loop antenna at 20 MHz operating frequency has been designed.
The antenna developed here has the maximum gain in the directions perpendicular to the plane of the loop having a radiation efficiency of 99.93%.
The wavelength corresponding to the operating frequency of this circular loop antenna is found to be 14.99 m.

June 2021 – July 2021
Effect of Temperature and Atmospheric Pressure on Muon Flux
The hourly flux of 1st March 2021 and 2nd March 2021, the temperature of the onboard thermometer and the pressure sensor on the DAQ board of the detector, and the average flux and the average temperature of the Batavia, IL of nearly 3 months with a gap of around 5-10 days in each reading (Basically for a wider range of data) have been used.
A linear negative correlation has been observed between cosmic ray count and atmospheric pressure. But the value of the correlation coefficient is less.

Detection of Muon near earth's surface and Special Relativity
The dataset from 4th October 2021 to 6th October 2021 of the Fermilab test Array, Batavia was analyzed to measure the velocity and lifetime of muons.
It was calculated that without taking into account special relativity (non-relativistic frame attached to earth), on average, the survival ratio of muons predicted to be obtained at ground level would be 1.85× 10-6.
Considering the special relativity (relativistic frame), the survival ratio of muons predicted to be obtained at ground level would be 0.0502 (out of approx. 1 million muons that formed in the upper atmosphere).

This project has been published in the ICD_2021 booklet at the DESY site.

The study of the Effect of Earth’s Magnetic Field on Muon Flux
Yearly muon flux data of 2014, 2018, and 2021 to analyze the correlation between muon flux and various components of earth’s magnetic field.
The study of the effect of High Energetic Events Like Supernovae Ia and II on Muon flux.

A simplistic view of smartphone sensors
The project has been done on the simulation site Tinkercad, using 3 sensors(Temperature, ambient light, and force) and 2 microprocessors (Arduino UNO and micro: bit).
The Arduino processes data obtained from the 3 sensors and the micro: bit functions as a sensor of its own, acting as a horizontal compass.

Automated Hand Sanitizing and Door Unlocking System
The usage of temperature, force, ultrasonic sensors, and a servo motor operated by an Arduino Uno has been done.
The results are shown through the operation of the servo motor, which operates only when all input variables are in the set composition.
