Development of Air Quality Monitoring System in Closed Environment
For closed environment, the characteristic is that the confined space is small and it doesn't flow
with the outside world, it will produce nausea, dizziness, weakness and other symptoms if one stayed in
that environment for long time. For this, developing a monitoring system of air quality in closed
environment has theoretical significance and great value. In this paper, a modular design method is used
to design a closed air quality monitoring system, The air quality monitoring system is composed of a main
board and detection modules. When the measured closed environment is changed, it is only necessary to
add or reduce the corresponding detection module, which increases the flexibility of the system and the
convenience of later maintenance, and evaluation algorithm based on fuzzy mathematics is established.
The measurement and air quality evaluation experiments are carried out using the developed monitoring
system, The results show that the air quality evaluation algorithm can effectively evaluate the
environmental air quality, and the measurement accuracy of the environmental parameters can meet the
relevant standards.

The authors collected air quality data from various Indian cities from 2018 to 2021, including levels of pollutants like PM2.5, PM10, NO2, O3, and SO2. They analyzed trends over time and the impact of lockdowns. Different time series forecasting algorithms (ARIMA, Prophet, LSTM, ETS) were used to predict future air quality levels. ARIMA provided the best predictions. The analyses and predictions were developed into a dashboard application to visualize trends and comparisons of the different algorithms. The work provides a model for predicting air quality that can help identify heavily polluted regions and reverse air pollution in India

AIR QUALITY INDEX MEASUREMENT
Nowadays by seeing the present scenario AIR is the essential element to live & Air Quality Index is a tool to distinguish the benefit of air quality. There are different methods to identify AQI, based on many impurities viz. PM2.5, PM10,CO were used to compare ambient air quality. By calculating AQI we define the quality level of air to be good, moderate, and hazardous as AQI is calculated by using the reference of "The United States Environmental Protection Agency" We are using thingspeak server to fetch the data into the cloud, so anyone can access the data in their respective location. We are not only focusing on stationary measurement but also on the real time value measurement of AQI. Which helps common people to access the Air Quality Index throughout the city and help them decide to stay in a cleaner air environment? Thus the foremost idea of AQI is to inform people about their air quality so they can step to defend their health.
IRJET- Level Loop Measurement using IoT
This document describes a system for remotely monitoring liquid levels in tanks using ultrasonic sensors, WiFi modules, and an Arduino board.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
- These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.
