 Abstract

Abrasive Water Jet Machining (AWJM) is one of the recent Non-traditional manufacturing technologies in which mixture of high pressure water and Abrasive particle is used to remove the surplus material without any distortion and microstructure changes. In AWJM, major problem is to produce rough on the cutting-edge during machining on circular path. The main aim of this research is to cut disc brake of automobile vehicle using AWJM to optimize surface roughness and process parameters. In this study parametric study of traverse speed, nozzle diameters, abrasive mass flow rate, and stand of distance were carried out with disc brake of material SS420 with 4 mm thickness. Experiments are performed on Karolin Machine Tool (KMT) at Param Technocrafts and JRD Technocrafts with nozzle diameter 0.25mm, 0.30mm, 0.35mm. The surface roughness is measured by using SJ 210. Optimization of surface roughness is obtained through response surface methodology. Optimum value of surface roughness is 0.45-degree, 2.356 micron obtained for stainless steel 420 materials.

The paper is intended to study the perception of teachers and students towards effectiveness of online teaching and assessment during COVID-19 pandemic. Descriptive survey design has been used. The teachers and students of undergraduate and postgraduate level participated in the online survey. Total 200 teachers and students from three Colleges were selected as sample of the study. Self developed perception scales were administered. The collected data were analyzed through using t-test, ANOVA. The research findings revealed that there is no significant difference in perception towards effectiveness of online teaching and assessment in relation to gender and academic streams among students and teachers. Teachers and students have a favorable perception towards effectiveness of online teaching and assessment.

 Abstract

Education is very important, especially during uncertain times. The Indian government has created a new plan called the National Education Policy 2020 to improve the education system and make it better. The plan focuses on creating good quality universities and colleges that offer different kinds of education. In this paper, we have studied the plan and suggested some changes to make it even better. We also looked at how universities should follow this plan and made recommendations on how to improve the education system across the country.

 Abstract

As a result of their superior eco-friendliness over synthetic-fiber based polymer composites, products made from natural fiber reinforcement have become more popular in a wide range of applications. This paper describes the review of Mechanical Properties of Fiber Reinforced Composites. Renewable resources such as natural fibers have been continually replenished for thousands of years thanks to both nature and human innovation. As a bonus, they don't have any negative impact on the environment due to their carbon footprint. All of these fibers are biodegradable, inexpensive, low-impact, have high specific strength, are not abrasive, and can be replenished quickly. For these reasons, natural fibers have recently gained favor among scientists and researchers as a potential replacement for synthetic fibers in fiber-reinforced composites. This article acted as a survey of fibers and their uses throughout history.

 Abstract

When it comes to the South Asian economy, Thailand is a major player. Bangkok, the country's capital, is the country's social and economic centre. It piqued the interest of several foreign retailers, who subsequently set up shop in Thailand. Its retail sector is developing rapidly to accommodate the needs of internet-enabled shoppers with a wide range of preferences. As a result of the pandemic, the Thai economy as a whole and several economic sectors have suffered. The expansion of Thailand's consumer market has been propelled by the country's improving economic situation. Thailand's food retail industry is forecast to develop mildly to moderately, with online food retail witnessing significant growth despite the predicted contraction of 5-10% for the first quarter of 2020 due to the effect of the epidemic on the retail sector as a whole. While the retail industry as a whole in Thailand has been hit hard, convenience shops and online shopping have thrived despite the downturn. Grocery product sales via the internet distribution channel increased dramatically during the -triggered shutdown period in 2020. Rapid development in contemporary retail was seen in Bangkok and other highly urbanized cities as a result of rising tourism and a number of government initiatives, including the opening of the domestic market to international investors and the use of cutting-edge technology in the retail industry.

 Abstract

This paper gives information about the development of higher education in Kerala during the post liberalization period. The expansion of higher education in Kerala has been significant since the introduction of economic reforms in 1991. There was also an increase in the number of self-financing or unaided Arts and Science colleges offering courses especially in the non-conventional subjects. Number of higher education institutions under government sector has increased only in engineering, nursing and polytechnic colleges. Further a close look at the distribution of technical institutions reveals a sincere attempt from the part of the government to bring job orientation to the youth of Kerala. The paper gives an attempt to explain the development of higher education in Kerala during post liberalization in all sections of higher education.

ABSTRACT: Today, when we move out from our house the one thing that we essentially take along with us is our mobile phone. Being the basic device to communicate with each other, our smart phones have turned into the basic need because of the utility it provides to us. All of this is possible due to adoption of technology and innovations to make our lives easier. Combining technology in financial system is one of the best things that has happened in this digital era that we know as FINTECH. The following paper studies the FINTECH basics and its key areas along with some light upon current scenarios of fintech adoption globally. The following research paper is descriptive in nature and employees the secondary source of published data.

 Abstract

A popular technology for companies of all kinds, including Micro, Small, and Medium Businesses, is cloud computing (MSMEs). The advantages of cloud computing for MSMEs are examined in this research, including lower prices, more scalability, higher accessibility, and improved security. The use of cloud computing by MSMEs faces several difficulties, including restricted internet connectivity, a lack of technical skills, and worries about data security and privacy. The report argues that MSMEs can benefit from working with cloud service providers, establishing best practices for data security, and adopting cloud-based software solutions suited to their particular requirements to overcome these difficulties. According to the study's findings, cloud computing can help MSMEs compete successfully in the digital economy and increase productivity and profitability.

 Abstract

The aim of present study is to find out the effectiveness of trans-disciplinary approach in management of children with autism. Trans-disciplinary approach is an approach where in all related professionals along with case manager, child and family is involved in the process of assessment and intervention.. The comprehensive intervention programme is implemented by the case manger with the support of parents and under the guidance of professionals. This trans-disciplinary approach helps the family to understand the intervention process more precisely. In the current study, the index child has been provided a 3 months intervention under trans-disciplinary approach. Analysis of pre and post scores in selected assessment tools reported significant improvement in developmental domains of the child. This approach has also been contributing for enhanced involvement of parents in planning and implementation of intervention process. The current study concludes that trans-disciplinary approach, is effective for children with autism especially in Indian conditions.
