Implementation of digital watermarking using hybrid decomposition for cryptography applications
A method of depicting a novel image based on wave discrete conversion (DWT), Hessenberg decomposition (HD), and single-digit decomposition (SVD) is suggested in this paper. The embedding process is done first and in this process, the host image deteriorates into multiple sub-bands with multilevel DWT, and the resulting coefficients are used as inputs for Hessenberg decomposition. Simultaneously, the watermark works on SVD. The watermark is finally attached to the host image with the measurement feature. This proposed method is compared to other research activities under various spoof attacks, such as filter, noise, JPEG compression, JPEG2000 compression, and sharpening of the attack. The test results show that the proposed image display has a good trade-off between durability and invisibility even if the watermarks are large in size.

Sustainable toilets by using lightweight precast concrete panels
With increasing concern over the excessive exploitation of natural aggregates, synthetic lightweight aggregate produced from environmental waste is a viable new source of structural aggregate material. The uses of structural grade lightweight concrete reduce considerably the self-load of a structure and permit larger precast units to be handled. BS EN 12504-4. 2004. Testing concrete. Determination of ultrasonic pulse velocity. The mechanical properties of a structural grade lightweight aggregate made with fly ash and clay will be presented. Indicated that water absorption of the green aggregate is large but the crushing strength of the resulting concrete can be high. The 28-day cube compressive strength of the resulting lightweight aggregate concrete with a density of 1590 kg/m^3 and respective strength of 34 MPa. Experience of utilizing the green lightweight aggregate concrete in the prefabrication of concrete elements is also discussed.

Automatic Arboretum Monitoring System
The greenhouse is climate-controlled structures specially designed for growing plants. Most greenhouse systems use manual systems for monitoring the temperature and humidity which can cause discomfort to the worker as they are bound to visit the greenhouse every day and manually control them. Also, a lot of problems can occur as it affects the production rate because the temperature and humidity must be constantly monitored to ensure the good yield of the plants. Internet of Things is one of the latest advances in information and communication technologies, providing global connectivity and management of sensors, devices, users with information. So the combination of IoT and embedded technology is used to monitor the fields. The thermo-Electric cooler is used to change the temperature regarding the surrounding. Usage of this cooler helps to grow the rare medicinal plants inside the greenhouse. Sensors like temperature, humidity, soil moisture, and Ph are the parameters used to check the healthy state of the soil.

Designing of automatic hand sanitizer robot
There is new broad health crisis bargaining the world with the ascent and flare-up of 2019 novel coronavirus (2019-nCoV) or the genuine extraordinary respiratory condition coronavirus 2 (SARS-CoV-2). It has spread to the world and tainted people with Covid- 19 infections. The transmission of the disease was viewed as spread through person-to-person which makes it easily diffuse. The infection spreading starts from the infected droplets during sneezing or coughing. These droplets can, in any case, live on inanimate surfaces even in the air, and transmitted the infection to humans. In order to reduce the spread of coronavirus, any contacts between people and potential carriers of the virus have to be limited. In current circumstances, social distancing and constant disinfection of public places become a necessity. The mask and the sanitizer are provided everywhere to protect the people from spreading the virus and to kill the virus from a human hand. The virus is spreading from the human hand and mouth saliva. The mouth spread is controlled with the mask cloth and the human hand is controlled by the hand wash sanitizer. The hand touch while pressing the dispenser usage also spreads from human to human. There should be an automatic hand wash sanitizer dispenser, to control and maintain the spread from human to human. Though, nowadays it is essential to sanitize hands, touching the same bottle surface already used by someone may increase the risk of contamination. The aim of this study is to design and develop a smart contactless hand sanitizer-dispensing system using IoT based robotics technology. The robot functionality has been examined, the present system has the ability to hand disinfect with less time consuming and minimal human interactions.

Safety defence device for the eternal feminine
As we know the present era is with equal rights, where both men and women are taking equal responsibility in their respective works. Hence women are giving equal competition next to men in all fields. Every single day women and young girls from all walks of life are being assaulted, molested. Because of these reasons women can’t step out of their house. The only thought haunting in every women’s mind is when they will be able to move freely on the streets even on odd hours without worrying about their security. In critical situations, the women will not feel insecure or helpless if they have some kind of safety device with them. We propose to have a device, which is the integration of multiple devices. The implementation of the smart device is basically split into two sections the first part ensures to capture the image of the culprit. The captured image serves as valid proof against the one who has committed the crime. The second section deals with the defense application as we tend to concentrate more on providing self-defense for the women in danger. By making self-defense the first priority we make sure that occurrence of the critical situations is eliminated. The self-defense feature is capable of working in any of the circumstances. When the registered fingerprint is scanned, the GPS tracks the location and the GSM sends messages to the police and to the family. The buzzer in the device alerts the nearby people. These two factors form the combined self-defense application and help the victim to escape from the danger.

A warning and passenger safety system for railway compartment using WSN
The railway industry plays a critical role in transportation and transit systems attributed to the ever-growing demand for catering to both freight and passenger. The present work is based on developing an automatic closing and opening of gates near the railway crossing. Generally, railway gates are manually handled by gatekeepers. The gatekeeper will get the information about whether the train is coming or not, from the nearer station. Once the train leaves the station, the station in charge will give the information about the arrival of the train to the nearest gatekeeper and alert him to get ready to close the gate. This human intervention can be avoided by using this system. If the arrival of the train is late due to some reason, this information will not send to the gatekeeper instantly. Hence the gate will remain closed until the train arrives this delay will cause the traffic problem near the gates and makes the people get into trouble. This will be prevented by using the system. In this system, we are using a relay driver to control the gate through WSN. The objective of this system is to create safety for women if they abused by someone, theft their things, and illness of passengers in the compartment by pressing the emergency request to send information through Zigbee to communicate in the nearer station. In this system, we are implementing the RFID reader to avoiding the fraud of passengers to travel without taking a ticket. This project helps us to avoid the hindrance happens from the passenger in the compartment and shows the information in the PC user of the railway station.
