In this article, introduce a metamaterial for microwave absorber applications based on a variant of the symmetric plus-shape resonator. This MA has two absorption peaks, making it suitable for Ku frequency band use. The MA unit cell built on a cheap FR4 substrate. The unit cell's resonator is designed in the form of a four-plus-shape with an eight-square-point in one of the corners, and its dimensions have been tweaked to achieve maximum absorption peaks of 99.04%, and 99.90% at 12.32 GHz, and 16.00 GHz, respectively. Analysing the surface current, electric and magnetic fields, permittivity, permeability, and normalised impedance provides insight into the nature of metamaterial and absorber. The incidence and polarization angle insensitivity of the suggested dual-band absorber allows for pretty much constant absorbance efficiency when the angle is changed. Moreover, for both TE mode and TM mode, the developed metamaterial absorber demonstrates near unity absorption for polarization and oblique incident angles up to 90°. These are single negative metamaterial qualities. The fact that the patch as a whole is rotationally symmetrical is one of the most important factors in determining whether or not it will retain its polarization-insensitive quality. Because of its outstanding insensitivity performance and nearly perfect absorption, it could be a good option for use in Ku band applications.
Attack of Township
(Daffodil International University, 2018-05) Moniruzzaman, Md
In Attack of township players have to collect resource like food (from animals), wood (from tree). Using the resources they can buy/update buildings, troops etc then using those troops they can occupy other players base. After occupied the base attacker will get certain amount of resource from the defenders until defenders liberate themselves or attacker release them. Background is a set of events for a plot presented as preceding and leading up to that plot. In our project it’s a multiplayer game emphasizing logical thinking and planning. Tactical organization and execution are necessary. Player has to make decision about the actions. All the actions are on the hand of the player. Project is a multiplayer strategy game on android platform. The purpose of this project is to provide a virtual image of running an empire. Player will learn by the manipulation of the environment through the game. We demonstrate the action flow between input, script and the display. We are working mainly on the levels, animations, objects, scripts. We are not working with the web or IOS platform Developing a game from scratch is a much challenging for a company. It requires much investment in terms of effort and cost. We make this game for business purpose as we will distribute this to the client market like google playstore, amazon store etc.

Design and implementation of urban search and rescue robot
(2018) Moniruzzaman, Md; Zishan, Md Saniat Rahman; Rahman, Sabbir; Mahmud, Sanwar; Shaha, Antar
Disasters unsettle the economic and social stability of society. Shortage of skilled rescue workforces, as well as the risks involved in search and rescue operations, are becoming foremost problems during an emergency situation. To solve these problems, we have designed and implemented an Urban Search and Rescue (USAR) robot. The robot is designed and implemented in such a way that includes the application of digital electronics, embedded programming, digital signal processing and digital sensors. This USAR robot uses the microcontroller PIC 16F690 to control its movement by using a radio frequency module and PIC 16F73 to collect the sensor’s data and transmit the data through Bluetooth module. These are low power and costeffective chips. The PIR sensor, Co2 gas sensor, and temperature sensor will collect the data of the disaster area and transmit the data to the service station. Even though, a camera is operated for visual purpose. In this paper not only we have designed and implemented USAR robot but also we tested and analyzed the result.
Navigating the Contemporary Landscape of Food Waste Management in Developing Countries: A Comprehensive Overview and Prospective Analysis
(Elsevier, 2024-06-19) Rahman, Tawfikur; Deb, Nibedita; Alam, Md Zahangir; Moniruzzaman, Md; Miah, Md Shohidullah; Horaira, Mohammad Abu; Kamal, Reashad
This study employs a comparative analysis method to examine variations in food waste (FW) generation between developed and developing nations, focusing on income levels, population growth rates, and community engagement in waste management. Quantitative data from Taiwan, Malaysia, and Bangladesh are comprehensively analyzed using regression analysis and descriptive statistics. Results indicate that Taiwan, with its stringent regulatory frameworks and advanced recycling technologies, generates significantly less FW per capita compared to Malaysia and Bangladesh. Malaysia shows moderate levels of FW reduction efforts, supported by varying degrees of community participation, whereas Bangladesh faces challenges with both regulatory enforcement and technological adoption. The study proposes an integrative waste management model emphasizing regulatory compliance rates, community participation metrics, and technology diffusion indices to effectively address FW challenges. These findings underscore the importance of tailored waste management strategies aligned with economic and demographic contexts of developing nations. Policymakers and waste management practitioners can leverage these insights to establish targeted FW reduction goals and enhance recycling initiatives. The research highlights the urgency of integrated waste management approaches to mitigate environmental and public health risks associated with FW mismanagement, advocating for evidence-based policies supported by robust quantitative analysis.
