Abstract

Climate change caused by human activity has led to abnormal rainfall in India. Agriculture is a crucial source of income for the Indian Government and the abnormal rainfall patterns pose a significant threat to the industry. These fluctuations in rainfall have caused damage to homes, and infrastructure, wash away crops and destroy water sanitation. Unusual rainfalls are also affecting the Rooftop restaurants. The Government, Roof Top restaurant owners, and farmers are all seeking solutions to address the impact of climate change. One potential solution is the development of a Smart Roofing System that can detect rainfall and respond accordingly. The Proposed system would use a Rainfall Sensor to detect rain, which would then send signals to a Wi-Fi-enabled board. The board would then activate dc motors, opening the roof to protect against rainfall. When the Rainfall Sensor detects no rain, it sends a signal to the board to reverse the direction of the motors, closing the roof. The implementation of this Smart Roofing System could help minimize the damage caused by unusual rainfall patterns and help towards the development of a sustainable environment. With a Smart Roofing System in place, roof-top restaurant owners could continue their service during periods of heavy rain, ensuring minimal disruption to their business. Overall, the development of a Smart Roofing System could help protect India’s infrastructure, agriculture, and economy from the adverse effects of climate change with minimal cost.

1 Introduction
India is particularly vulnerable to the effects of climate change due to its geography, high
population density, and reliance on agriculture. Causes for the Climatic Changes are human
activities such as the burning of Fossil Fuels, Deforestation, industrial activities, and
Transportation release a large number of harmful gases called Green House Gases such as
carbon dioxide, Methane, Nitrous Oxide, etc. Climate Change is also caused by a few natural
factors such as solar radiation, volcanic eruptions, and natural variability of the climate
system. The effects of these Climatic Changes are huge across the country’s environment,
economy, and society. India is experiencing more frequent and severe heatwaves, floods,
droughts, and cyclones due to climate change. It causes changes in rainfall patterns which
also impacts agriculture and businesses of rooftop restaurants. It leads to the spread of
diseases. Climate change is causing changes in the spatial distribution of rainfall in India,
with some regions experiencing more rainfall, while others are experiencing less. This is
leading to disparities in water availability and impacting agricultural productivity.[12] It is
also expected to have significant economic impacts on the country, including a decrease in

agricultural productivity and an increase in healthcare costs and sustainable development of
the society and utilization of the resources.
Urgent action is needed to reduce the above-mentioned impacts of Climate Change.
Framers usually sun-dry their crops before taking them to the market. They adopt traditional
methods to dry the cultivated crops. The usual way is exposing the crops to sunlight by
spreading them on the floor. But during times of unusual rains, the crop becomes wet which
leads to spoilage of the crop, increased dry time, and decreased quality. Smart Roofing
System can sort all the above-mentioned problems. In Smart Roofing System, the roof which
is a waterproof sheet spreads over the area. [11] Smart Roofing Systems include weather
sensors to track climatic conditions like temperature, wind speed, etc. In the case of Open-
Top restaurants the data collected by the sensors help in making decisions about opening and
closing the outdoor dining area. Similarly, in the case of agriculture, the smart roofing system
can integrate sensors to detect factors like temperature, humidity, sunlight intensity, and soil
moisture. This data can be used to protect the crop from getting damaged by indicating when
to open and close the roof at the time of unusual weather conditions.

focuses on the design and development of an innovative solution for protecting clothes on a
clothesline from rain and providing a convenient retractable roof system. The proposed
system utilizes an automatic retractable roof mechanism that is activated based on weather
conditions. It incorporates sensors such as rain and light sensors to detect rainfall and control
the movement of the retractable roof accordingly. The system can be implemented using

3 Methodology
Addressing all the limitations in the existing systems, the proposed model consists of a
system that uses a Rainfall sensor to detect rain. This data on rain is sent to the Wi-Fi-enabled
board. The board then sends the signals to the motors. The motors rotate to make the roof
open and close according to the requirement. The owner gets notified about the roof status
via a mobile app.
[10] The implementation of the intelligent roofing system incorporates sensors to collect
rainfall data and assess rain conditions. A predefined threshold value is employed for rainfall
calculation. Sensors offer real-time data for operations based on threshold or user
preferences. Data collection is followed by establishing connections between system
components to enable communication. For seamless interaction between sensor data and
smart roof actions, a centralized control system is introduced. This system responds
automatically to rain changes or user inputs, facilitating roof opening and closing. A user -
friendly application interface is developed to monitor roof status changes. Rain sensors
transmit data to a cloud-connected Wi-Fi board, which activates motors for timed roof
opening and closing. Users receive notifications about roof and rain status via the application.
As a result, the motorized smart roof attains automation, enhancing efficiency and user
convenience.

During the rainy season, the majority of people feel anxious when they are drying clothes. This anxiety will increase when drying clothes but is outside the house, and the house is not there. From that incident people became reluctant drying clothes in an open place, because I was worried that the clothesline would get wet in the rain. When the rainy season the majority of people dry their clothes on the terrace of the house, this is done to Avoid drying clothes exposed to rain when the owner is left doing outdoor activities house. From the description of the problem above, the author found the idea to make a towing device clothesline that can work automatically. The tool uses an Arduino microcontroller The Uno is coupled with a rain sensor and a Light Dependent Resistor sensor. The way this tool works is detects the surrounding weather through the rain sensor and LDR sensor, when the sensor does not receive light then the tool will translate it will rain, so the tool will attract clothesline in a place protected from rain. When the sensor detects sunlight the tool will translate that the weather around is hot, so the tool will pull the clothesline a place exposed to the sun. While the rain sensor detects droplets from the water rain.Hopefully with the creation of an automatic clothesline puller can help people reduce anxiety when drying clothes in the rainy season.

Authorship attribution is one of the important problem, with many applications of practical use in the real-world. Authorship identification determines the likelihood of a piece of writing produced by a particular author by examining the other writings of that author. Most of the research in this field is carried out by using instance based model. One of the disadvantages of this model is that it treats the different documents of each author differently. It produces a matrix per each document of the author, thus creating a huge number of matrices per author, i.e. the dimensionality is very high. This paper presents authorship identification using Author based Rank Vector Coordinates (ARVC) model. The advantage of the proposed ARVC model is that it integrates all the author's profile documents into a single integrated profile document (IPD) and thus overcomes the above disadvantage. To overcome the ambiguity created by common words of authors ARVC model removes the common words based on a threshold. Singular value decomposition (SVD) is used on IPD after removing the common words. To reduce the overall dimension of the matrix, without affecting its semantic meaning a rank- based vector coordinates are derived. The eigenvector features are derived on ARVC model. The present paper used cosine similarity measure for author attribution and carries out authorship attribution on English poems and editorial documents Index Terms—Threshold, Common words, Integration, ARVC model, SVD technique.

Due to the advancement of Technologies, many companies and organizations today have huge databases, that grow to a limit of millions of records per day. This data generation and storage has become faster than ever. This resulted in databases of unbounded growth. The data even changes over time. As a consequence, if the data cannot fit into memory, it may be necessary to sample a smaller training set. The data streams have recently emerged to address the problems of continuous data. The mining of such data streams is a unique opportunity and even challenging task. Mining with data streams is the process of extracting knowledge structures from continuous, rapid data records. Due to increased streaming information, data stream mining has attracted the research community.
