Pranta Sarker

I am a Lecturer in the Department of Science and Engineering at North East University Bangladesh. After completing my Bachelor's degree (BSc.(Engineering) in Computer Science and Engineering), I joined my University in May 2018. Alongside, I have been involved as a Technical Reviewer in a Scopus-indexed journal, namely, the International Journal of Computing and Digital Systems.

The research field of my undergraduate thesis was data compression. I worked on the Huffman-based data compression technique to optimize decoding time for Huffman codes by introducing a new data structure. Further, the research has been extended, and I have made some publications on the knowledge. Nevertheless, currently, my research interest is in artificial intelligence, machine learning, privacy, security, data structure, and algorithms.

As a faculty member, the primary role involves delivering engaging and informative lectures to students, utilizing innovative teaching methods to enhance comprehension, designing and implementing fair assessments, grading assignments, and providing constructive feedback to aid student development. In tandem with teaching, my role involves conducting thorough research in my field, publishing scholarly articles, and contributing to the academic discourse that allows me to publish Scopus-indexed articles, enhancing enthusiasm in the research area. To describe the administrative rules, I have participated in making an Outcome Based Education (OBE) curriculum for several courses in the program instructed by UGC. In addition, I am still gathering experience as a member of the Result Verification Committee and an Assistant Proctor to serve the proctorial rules at the university.

However, I could bear a good knowledge of C, C++, Java, and Python programming languages since I was a competitive programmer in my pupil life. In addition, I have participated in eminent programming competitions such as ICPC, NCPC, and IUPCs for several years. However, after joining as a faculty member, I helped enthusiasts by conducting several classes and workshops related to competitive programming, which assisted in flourishing my coaching experience. Thus, I found sound involvement in prestigious programming competitions as a coach. Apart from this, I utilized Python's Tkinter feature to develop some exciting desktop projects. Furthermore, I am acquainted with PHP, a backend programming language and HTML, and W3CSS for developing many Web projects. All of this learning delighted my studying career at the university.

A Faster Decoding Technique for Huffman Codes Using Adjacent Distance Array

The evaluation of Huffman-based algorithm can be measured in two ways: one in terms of space and another is decoding speed. As memory requirement is going to be reasonable, the time effectiveness of Huffman decoding is more significant. So, this research concentrated on making the decoding speed faster for Huffman codes as well as maintaining the compression ratio for text data. For this, a new technique based on an adjacent distance array is introduced here. Adjacent distance array can save the distances for each adjacent symbol by calculating their ASCII values. Also, we have used a threshold value so that we can skip large codeword for all the adjacent symbols that would be produced by traversing whole Huffman tree. During the decoding process, the adjacent distance array is used to decode adjacent symbols by computing the distances instead of traversing the whole Huffman tree. We have described the encoding and decoding processes for the proposed technique. Besides, we have tested the proposed method on a few renowned corpuses and compared the performance with existing Huffman-based methods. Therefore, we have found that the proposed method performs more effectively in terms of compression–decompression time.

Method of Adjacent Distance Array Outperforms Conventional Huffman Codes to Decode Bengali Transliterated Text Swiftly

Pranta Sarker, and Mir Lutfur Rahman

International Journal of Computing and Digital Systems, Jan 2022

This research works on high symbolic Bengali text and transforms it into corresponding less symbolic English complying with the transliteration method. The Huffman-based approaches serve to compress retaining the original quality of the data. On the other hand, faster encoding and decoding is the most sophisticated sphere in data compression. We propose an adjacent distance array, a novel data structure based on the Huffman principle for encoding and decoding the character of transliterated text. The encoding and decoding algorithms have been explained for the introduced modus operandi and juxtaposed with conventional Huffman-based algorithms. Our research is outdoing than any regular Huffman-based algorithms, concentrating on the speed of the encoding and decoding manner discovered after estimating all decisions.
