Reversible data embedding using difference expansion scheme for watermarking

Reversible Data Embedding is a lossless reversible data embedding technique that embeds invisible data known as payload into the input image and uses the Difference Expansion (DE) technique. This paper uses a DE-based reversible scheme to reduce the amount of auxiliary information embedded and to increase the watermark length. The key concepts discussed in this paper are: Reversible Embedding, Extraction, and Restoration of the original dataset with minimal distortion. By observing redundancy, reversibility can be explored. Payload, PSNR, and Watermark Length have been used to assess the effectiveness of DE. Four data sets have been used - Lena, Boat, Airplane, and APC. For Lena, the payload obtained is 31.14 and the payload was found to be 0.76 implying that more information can be embedded in an image than in the standard methods.

The feasibility of using Supercritical CO2 cascade cycle in the combined cycle

Electricity is a form of energy that expected to be increased and grown in most industrial sectors. The Gas turbine (GT) the equipment used to convert natural gas to electricity because it is cleaner than other fossils fuels. Using a stand-alone GT has many disadvantages like the low efficiency which about 30-40 % and most importantly is the waste of energy that goes through the exhausted gases. The bottom cycle is a solution to recover this energy. Commonly, heat recovery steam generation (HRSG) is used to utilize the waste energy but using HRSG is considered not efficient although it can increase the system efficiency to 60 %. The cycle used to recover the heat is called also a bottoming cycle. Besides, the requirement of the weight and space availability in mature onshore fields and offshore fields. The sCO2 cycle is considered a promising alternative bottoming cycle due to the additional produced power and also its compactness. This study evaluates the cascade sCO2 cycle used by (Kim et al., 2017) in comparison with the traditional steam Rankine cycle. To make this comparison fear, once through (one-stage) is combined with the bottoming cycle. The base case was remodeled by Aspen HYSYS software and was validated with the existing topping cycle a bottoming cycle studied by (Følgesvold et al., 2017). The thermodynamic analysis was evaluated to show the possible increase in the produced power. the results indicate that the cascade sCO2 cycle produces higher power.

Voluntary disclosure practices- A comparative study of top public and private sector banks in India

A voluntary disclosure practice plays a major role with respect to stakeholders. It creates a high quality of financial and non-financial information which is useful for the stakeholders to make the decisions. The voluntary disclosure practices provide the information to the stakeholders to make the investment decisions. Therefore, it is necessary for every bank to make timely and full disclosures in the annual reports of the banks. This paper is an attempt to examine the voluntary disclosure practices prevailing in commercial banks in India. In addition to this, a comparative analysis of voluntary disclosure practices of public sector banks and private sector banks in India for the period 2018-2021.

Thesis

A new interleaved ZVS resonant converter using Dickson capacitor configuration

A New Automatic Interleaved Dickson Switched-capacitor Converters (AIDSCC) and its ZVS resonant configuration are proposed. Different from the traditional Dickson switched-capacitor converter (SCC), the AIDSCC has a symmetrical configuration with functions of interleaved input current, small output voltage ripple, and decrease peak capacitor voltage strain. To improve the line regulation capability, one small resonant inductor is inserted and two bulky capacitor banks are changed through two smaller resonant capacitors, forming the Resonant AIDSCC. The transistors are ZVS became on and diodes are ZCS grew to become off through running above the resonance. With frequency modulation inside an affordable range, the voltage-gain variety of the Resonant AIDSCC is elevated substantially, even as sacrificing the most performance due to the higher conduction loss.

Wireless smart helmet with sensors for accident detection

In Countries like India, the major challenge is safety for two-wheeler riders. The rapid growth of two-wheeler vehicle road accidents is evident. According to a report by the National Crime Records Bureau (NCRB) In India, almost 2 lakh people die annually due to two-wheeler accidents. The government is forcing drivers to wear a helmet during driving but many of the riders are not following the rules. We would like to help society through our project, we would try to reduce the probability of deaths caused by two-wheeler vehicle accidents. In this project, we are introducing a Wireless smart helmet system that detects a person is wearing a helmet or not, and also the system can detect whether the person is drunk, here we have a Bluetooth transmitter in the helmet and a Bluetooth receiver at the bike. Two pushbuttons will be there to check whether the person is wearing the helmet or not. And an alcohol sensor is placed inside the helmet near the mouth of the rider to see whether the rider is drunk. If the accident takes place location of the accident will be sent to the predefined emergency contacts and there will be a buzzer sound and flashlight to grab attention so that the person gets immediate help. There is also another feature posture correction using haptic feedback which helps maintain the good posture of the rider. In this system, there is a switch that ensures the placing of the helmet properly. The conclusion of this paper is to prevent the accident while driving in the vehicle.

Smart sanitation system

According to India Today, 80% of 1.5lakh metric ton daily garbage remains exposed which can cause cholera, dysentery, typhoid, etc. Unhygienic toilets can result in urinary tract infections, hepatitis, E.coli, etc. Proper sanitation and timely maintenance are necessary to bring this number under control. While awareness is an important tool in India, we also need to start developing sustainable models of greener and smarter cities that use analytical solutions to solve problems faced by millions of people universally. When it comes to building smart cities for a greener tomorrow, proper sanitation, clean toilets, and efficient waste monitoring systems play an important role. Therefore to overcome the challenges faced in developing a better sanitation system, the proposed solution explores, primarily developing sensor-enabled solutions to improve waste monitoring and toilet sanitation across cities.
