Outcome Based Education is implemented in engineering colleges of India as per the guidelines issued by AICTE. It is a model which measures the performance of program on the basis of outcomes. The model can be used in evaluating the Program Educational Objectives and Program Outcomes. The paper discusses Outcome Based Education model and the attainments. We will discuss the process for the attainments of Program Outcomes and Program Educational Objectives for Undergraduate or Postgraduate program approved by AICTE, India. The attainment summary can be generated Batch wise and thus would help in comparing attainments of difference Batches.

The machine learning algorithms can be applied to educational domains for the prediction of results, analysis of weak students, to analyse other features in data apart from grades, technical education for calculating the attainments in outcome-based education etc. In this research the different classification machine learning algorithms are applied on datasets having features like student marks, family education, fathers’ job, attendance in school etc and model’s performance is calculated. Further, some features have been removed from the dataset in which the target value completely depends on student marks and further the models are evaluated. The results were very interesting, and it reveals that without knowing previous marks of students we can predict the future marks. The study would certainly helpful in educational institutions where we can find future grades which would help in finding the weak students. The execution time of different algorithms is also recorder on Graphics and Tensor processing units.

A decentralized private Blockchain implementation for academic document storage and document verification can add self-sovereignty to the process. It can dramatically minimize the time and cost of verification at various layers of verification. Blockchain would remove all the layers at all and it will provide immediate auditing of any document. So, the request and response will be truly real time in our case.Apart from speeding up the verification process, it will also increase the security of personal education data and will check all kind of misuse also. Putting documents on Blockchain would increase the security, because all the data would only be accessible by private key and proper authentication to that private key.We are proposing a private Blockchain that would be managed by some private vendors and only those vendors will take part in consensus. So, we are using proof of stake consensus in our case. We are using private IPFS database server for storing our documents over Blockchain. We are considering Ethereum Blockchain ecosystem in our case. Alternatively we can also use Hyperledger Fabric for implementation but that discussion is out of the scope for current document.

As per the guidelines issued by NBA (National Board of Accreditation) of All India Council of Technical Education (AICTE) Outcome Based Education is implemented in engineering colleges of India. The outcome based evaluation model measures the performance of UG and PG programs. The performance is based on calculating attainments of Program Educational Objectives (PEOs) and Program Outcomes (PO).In this paper we will discuss the process for the attainments of POs and PEOs for Post Graduate program approved by AICTE, India. The attainments are calculated by applying direct and indirect tools. The attainments summaries are generated Batch wise and a comparison of different Batches were made. The attained PEOs and POs would help in accomplishing Vision and Mission of the department.

The model of outcome-based education is based on achieving attainments at the end of each course by the students in any undergraduate or postgraduate program. It was implemented in all technical institutions of India as per the guidelines of All India Council for Technical Education, India. The attainments are calculated by deploying some direct and indirect tools. This include courses results, placements, projects and various surveys like alumni, employer etc. The paper discusses the attainment of Program Educational Objectives and Program Outcomes for any undergraduate or postgraduate program. In outcome-based education, certain targets are to be set on the basis of previous year performance of students and these targets are achieved in the form of attainments. In this research, a comparative study of last three batches of a postgraduate course is done in the form of attainments.

Due to revolutionary development in electronic and communication, mobile and handheld devices become the part of our daily life. As a result, volume of data traffic on Internet is increasing day by day. To provide unlimited, uninterrupted and content-rich services to these devices, the 5th Generation (5G) of network technology is emerged. 5G network can provide better Quality of Service (QoS) along with higher data rates than 4G network and have least latency. The paper appraisals various generations of wireless networks. Furthermore, it explores various challenges in implementation of 5G network and application areas of 5G network.
