 Abstract

The wavelet algorithms are applying the high level of image/data compression by using transforms. The main processes of wavelets are allowing some complex information such as images and videos to be decomposed into elementary forms. These processes are applied at different positions and balancesto rebuild with high precision. Signal transmission depends on the transmission of a progression of numbers. The series portrayal of capacity is significant in a wide range of sign transmission. The wavelet portrayal of capacity is another strategy. Wavelet change of a volume is the improved variant of Fourier transform. This chapter discusses more on applying an encryption standard by modifying the Discrete Wavelet Domain (DWT). In this work, the performance of modified DWT image encryption algorithms is measured and equated using the computation time. The entropy of the process determined the Randomness and provides how secure the image is encrypted. In this paper, we approach this issue by building up a scientific model for obviously scrambled pictures and afterward determine expectations and differences of NPCR and UACI metrics. Further, these hypothetical qualities are utilized to frame measurable theory NPCR and UACI tests. Basic estimations of tests will help in predicting an encryption standard. Thus, the topic of whether a given NPCR/UACI score is adequately high to such an extent that it isn't noticeable from ideally encoded pictures is replied by observing at real NPCR/UACI scores with comparing basic qualities. Test results utilizing the NPCR and UACI irregularity tests will determine the existing encryption techniques are really equivalent or not

 Abstract

In an internal combustion engine, the camshaft is a revolving cylindrical shaft that regulates the injection of vaporized fuel. As the pistons move in a reciprocating motion, the movement is turned into rotational energy by the crankshaft. Internal combustion engines, on the other hand, rely on camshafts to precisely timing their fuel injections. There are many cams on the camshaft, and they are utilized to open the valves either directly or through pushrods. It is necessary to have a direct connection between the crankshaft and camshaft in order to time the opening of values. Many different materials may be used to make an engine camshaft. Camshaft materials vary depending on the grade and kind of engine that is being built. Chilled cast iron is utilized in the majority of mass manufactured autos. Child cast iron is not only inexpensive, but it is also highly long-lasting and trustworthy. This is due to the fact that cold treatment enhances the metal's strength and hardness. This article examines and synthesizes the findings of a variety of researchers who have been working on cam shafts in an effort to discover the optimal outcome.

 Abstract

As health facilities and living standards have improved, the average life expectancy has increased dramatically, leading to a sharp increase in the number of elderly people. Savings play a vital role in the life of every senior because the future is unpredictable. Saving is therefore essential to meet future needs. This is only possible if they invest their money in land, gold and securities or keep the money in the form of deposits in banks. The aim of this paper is to study the factors that influence the investment behavior of retirees towards various investment avenues and also to identify the association between annual income and investment percentage. The study is based on primary data and collected from 120 respondents residing in Bangalore. For analyzing the data Chi-square and Correlation are the tools used. It is clear that retired employees are preferring Government/Public sector for investment which gives a slow or smooth and permanent return on investment with low risk. Employees with higher years of service are older in age and they are less aware of latest investment avenues and hesitate to take risky investment, they have to be properly educated about various latest investment avenues available.

 Abstract

Nowadays parking has become an expensive resource in almost all majorities in the world, and its limited availability is the concurrent cause of urban traffic congestion and air pollution. The common method of ending a parking space is manual where the driver usually and a space on the street through luck and experience. The situation is such that on any given working day approximately 40% of the roads in urban India is taken up for just parking the cars. The problem has been further exacerbated by the fact that nowadays even people from the low-income group are able to own cars. Particularly in the cities and the big towns, there is a problem where the supply demand ratio makes parking a problem for parking space providers, the motorists or both. This paper describes in detail how such a system can be implemented. It does not make use of any sophisticated devices or gadgets thereby ensuring it is economical to implement at a larger scale too! The prime aim of this research is to develop an application that allows the user to book a parking slot for him using his smart-phone and also make the payment online using internet banking. In order to book a parking lot, the only thing that the user needs to do is one-time registration and verification on the mobile application. Based on the current location of the user, the app provides all the nearest parking slots available. Then the user can pick the default shortest parking as provided by the app or pick any other custom location of interest. The user is expected to reach the allotted slot before time runs out and scan the QR code corresponding to the slot which was selected (as mentioned earlier). In case the user fails to reach the spot in time then either the user needs to book the slot again or the user is liable to pay an extra amount as fine to use the same slot. Once the QR code is successfully scanned the user can park his vehicle.

 Abstract

The demonetization resulted in a massive increase in digital payments. Government initiatives such as Digital India, as well as growing use of mobile and internet, are paving the way for exponential development in the use of digital payment. This shift to digital payments results in increased transaction transparency, which strengthens the country's economy. Many developments have occurred in the payment system in recent days, such as the introduction of digital wallets, UPI, and BHIM apps to facilitate the transition to digital payments. The purpose of this research paper is to investigate the positive impact on consumers. The current article examines the amount of customer acceptance of different digital payment solutions. While demographic factors such as age, gender, and income are important in determining this choice, we find persuasive evidence that a person's view of digital payment methods is influenced by her belief in the overall payments framework and banking system in general. We discovered that the degree to which previous experience with online fraud discourages the use of digital payments varies depending on the objective of the transaction.
