 Abstract

: The welded joints are used in various mechanical and civil structures which connects two or more parts aligned in same or different directions. The strength of weld joint largely depends upon its geometric design parameters. The objective of current research is to conduct numerical investigation on tube flange weld joint under torsional loading conditions. The designing and analysis of weld joint is conducted in ANSYS 20 software to determine stresses, deformation and safety factor. The weld parameters are then optimized to study the effect of these parameters on stresses generated.

There is an urgent need for copyright enforcement technologies which is increasing day by day in networked multimedia systems. These technologies can protect copyright possession of multimedia content. Image Watermarking is one of the technologies which have advanced to save digital images from illegal access. Content service transmission is a vital field of research to protect the ownership of the content. Also, Robustness against distortions and attacks is a crucial issue in watermarking. This issue has been taken care of greatly in this work. There are various methods to safe medical images, widely used are encryption, steganography, and watermarking, etc. Because of the watermarking benefits, it has gained great importance in the image security field. In this work, an advanced and improved method is proposed for hiding and the extraction of the binary watermark. This approach is proposed to watermark the biomedical information into a biomedical cover image. Along with the watermark extraction, the cover image is also extracted at the end of the receiver. A color image ".jpg" and binary image ".png" is taken as host and watermark image respectively. To increase the size of the security, firstly, the encryption of the watermark image is done by pseudo-random code and embedded in an RGB color cover image. The cover image is also decomposed by using discrete wavelet transform (DWT) and Singular Value Decomposition (SVD) methods. Both of the methods combined enhance the safety level of the proposed method. In short, the new SVD-DWT algorithm for the blind image is powerful in the fight against various attacks. DWT and Inverse DWT conversions were used to obtain four types of frequency images. To measure the efficiency of the proposed method, the test metrics are used such as MSE (Mean Square Error), PSNR (Peak Signal to Noise Ratio), and NC (Normalized Correlation).

 Abstract

In developing countries, cleaning water surface is a routine task. Collecting a huge number of floating dry waste, such as plastic bottles, encounters tension on the water surface and the garbage floats away due to the little drag force. The goal of this study is to create a robot that can perform floating trash scooping in place of humans, as well as to evaluate the effectiveness of the planned waste scoopers installed on the Floating Waste Scooper Robot. The design of the robot mechanism, waste scoopers, and control are all discussed. The waste is identified through the camera connected to robot. The waste is differentiated by the use of CNN algorithm. The YOLO is used for training purpose. Conveyer belt will help to drag the garbage waste floating on the water surface.

 Abstract

Covid-19 has impacted very much higher education at Bengaluru and it is impoverished by the pandemic. Covid-19 has impacted all people regardless of nationality, level of education income and gender. But pandemic has not caused the similar consequence to one and all and the vulnerables suffering very much. Students from privileged background who are well supported by their parents are learning very quickly with the alternative learning modes and opportunities. The students from poor and marginal families are facing the consequences of closing down of schools and colleges. The shift from classroom to online learning has created digital divide between rich and poor (Jyothi Bavia et al., 2021). In India about 32 crores learners stopped to move schools or colleges and all educational activities (Pavat Kumar Jena 2020) are brought to an end. The higher education in developed countries managed well to implement digital learning. But the situation in India is different. Students studying in the rural area are feeling very difficult to adjust to online due to different reasons and students are unable to attend project work properly.

 Abstract

It is observed that the buying behaviour of consumers for online grocery shopping is totally different from buying from physical markets. The purpose of this paper is to understand consumer perception towards online grocery shopping and measure sustainability. The current pandemic circumstance has driven individuals to turn to online shopping for groceries and imparted certainty among the buyers, this gives a more secure future to the online grocery market however to measure sustainability it is crucial to study the market once the situation has normalised. To gain insights into consumers' outlook on online grocery shopping and to understand the factors in their decision making process a survey was conducted among 120 respondents. The data collected through the primary as well as through secondary form was analyzed using various tools and descriptive statistics. Finally, the adequacy and efficacy of the study have been looked over and certain proposals have been recommended.
