    (Research and Development Wing, MIST, 2025-12-30) Mosharrof, Shakil; Nizami, Farhan Nasif; Mohtasim, Mahdi; Adib, Mahdi; Akhtaruzzaman, M.; Islam, Md Shofiqul; Rahman, Muhammad Towfiqur; Jahan, Hosney
    Managing land records is a fundamental duty of a government, ensuring the accuracy, consistency, integrity of ownership, and reliable transaction of data. Conventional paper-based or centralized digital technology-based land record systems are unable to hold the system trust, efficiency, and consistency, thus mostly demonstrate errors, fraud, and corruptions. On the other hand, blockchain technology presents a transformative solution. It offers transparent, tamper-proof, secure, and reliable approach for Land Record Management (LRM) system. In this study a blockchaindriven LRM system architecture with distributed ledger technology is presented. The proposed strategy enhances security and trust by ensuring transparency, acceptance, and accountability. The study also designs the smart-contracts algorithm in detail that facilitates land registration, ownership transfers, verification, and streamlining processes. The proposed architecture ensures automated functionalities with little human intervention, uplifting the system security. Moreover, the proposed blockchain architecture integrates finger-print biometric authentication that boosts the system strength in terms of security through identity verification. This mitigates the risks of errors, fraud, illegal modification, and unauthorized access. This article outlines a blockchain-based LRM framework and verified through implementation and testing, reflecting the potentiality of viable adoption of this advanced technology.

    Intelligent Head-bot, towards the Development of an AI Based Cognitive Platform
    (Research and Development Wing, MIST, 2023-12) Baki, Ramisha Fariha; Akhtaruzzaman, M.; Refat, Tahsin Ahmed; Rahman, Mouneeta; Razzak, Md Abdur; Majumder, Md Mahfuzul Karim; Islam, Md Adnanul; Ferdaus, Md Meftahul; Rahman, Muhammad Towfiqur; Naveed, Quadri Noorulhasan
    A cognitive humanoid head is an AI enabledhead-bot platformthat resembleshuman's cognitive abilities, such as perception, thinking, learning, and decision-making. The platformis able tointeract with human throughnatural language processingand recognizeindividuals, thusallowing seamless communication between two parties. No such cognitive platform has been introduced inBangladesh,thuscreatinganopenfieldtocontribute to the field of Machine Intelligence.Thisstudy aims to develop an AIbased humanoid head (head-bot) capable of imitating arange of expressions, recognizing individuals, and interacts with visitorsthrough general conversation.The head-botskeleton is developed using a number of hexagonal blocks of PVC sheet to mimic a human-head-like structure where LCD, camera, microphones, and speaker are mounted. Twoseparate Machine Learningmodels are designed for face detection andrecognitions, and voice enabledchat-bot implementation. The head-botplatform incorporates 2-DoF neck movements for various head gestures and face tracking.The Artificial Neural Network models are tested with accuracy of , and , for face detection andrecognitions, and speech recognitionsand response generation, respectively. According to the overall results and system performances, it seems that the proposed system has a number of good potentialsfor real life applicationssuch as entertainment, guidance, conversations, interactive receptionists, personal companion, medical assistance, and so on.
