Humanitarian vs pandemic responses: Vulnerable groups among Rohingyas in Bangladesh
(Institute of Development Studies, 2023-10-01) Nasar, Sameen; Aktar, Bachera; Hossain, Muhammad Riaz; Rashid, Sabina Faiz; BRAC James P Grant School of Public Health
The Rohingya diaspora is a politically sensitive humanitarian crisis for Bangladesh. The current Covid-19 pandemic poses a range of governance, demographic, and environmental policy challenges in an already fragile context. The ongoing situation combined with the pandemic requires a rethinking of humanitarian strategies to tackle the double burden of crises – humanitarian and pandemic. Drawing together evidence and experience from a mixed method participatory action research conducted among Rohingya refugees and the host community in Bangladesh, this article highlights the importance of the institutional readiness of research organisations to produce contextual interventions and targeted approaches in pandemic and humanitarian response for diverse communities. The article also reflects on the strategies researchers applied to create a knowledge network between researchers and implementers, which not only informed the study design and its selection of most vulnerable groups but also worked towards producing knowledge fit for purpose, where critical evidence was shared with key decision makers and policymakers. © 2023 The Authors.
Smart & scalable lighting system using motion sensors, light dependent resistors and ESP8266 controller board

Efficiency in our day-To-day lives has increased a IoT due to the implementation of Internet of Things (loT) based smart systems. loT has revolutionized our lifestyles with an event-based architecture in which every event triggers our devices to give us data. In this report, I have demonstrated such an event-based, efficient, and scalable way of implementing a smart lighting system in both commercial and non-commercial settings. The main objective of this report is to illustrate the fact that a scalable and event-based smart lighting system can be implemented in an economical way, saving both cost and energy. To implement the proposed system, I have used Passive Infrared Sensors (PIRs) and Light Dependant Resistors (LDRs) with a central microcontroller ESP8266 (WiFi Module) which continuously sends sensor data to the ThingSpeak cloud for data storage and further processing. In this paper, I have also demonstrated the scalability formulation that I have applied to make the storage and processing of big data easier and efficient in such a way that the system can scale up and down flexibly to accommodate the increment and decrement of sensor big data. As such, energy consumption can be reduced, while big data manipulation can be increased to a great extent. The proposed lighting system reduces the cost by 25 % and adjusts the power consumption to a great extent.

Dynamic traffic management system via GPS tracking and localization
(Institute of Electrical and Electronics Engineers Inc., 2018-07-03) Sadi, Sadman Hoque; Chakma S.; Department of Computer Science and Engineering
As cities grow in size and population, they all face the same fate of having very busy core city areas, with roads that were never designed to manage heavy amounts of traffic and no space for road network expansion either. Therefore the logical solution is to use the existing road networks more efficiently. Although people have come up with several techniques such as the use of loop detectors, image processing and transmission of vehicle speeds, they do not tend to be very practical or effective since the data those systems provide can either be very inaccurate or simply do not provide enough information for managing traffic properly in most scenarios. This paper is based on several algorithms which have been developed in order to use GPS data on vehicles, taking into consideration real world inaccuracies that can occur, to create a system of localization where traffic lights and road signs communicate directly to only a specific group of vehicles to which the traffic signal or road sign applies to.
Adapting disability research methods and practices during the Covid-19 pandemic: Experiences from the field*†

People with disabilities are often excluded from research, which may be exacerbated during the ongoing Covid-19 pandemic. This article provides an overview of key challenges, opportunities, and strategies for conducting disability-inclusive research during the pandemic, drawing on the experience of research teams working across ten countries on disability-focused studies. It covers adaptations that are relevant across the project lifecycle, including maintaining ethical standards and safeguarding; enabling active participation of people with disabilities; adapting remote research data collection tools and methods to meet accessibility, feasibility, and acceptability requirements; and promoting inclusive and effective analysis and dissemination. While this article is focused on adaptations during the pandemic, it is highly likely that the issues and strategies highlighted here will be relevant going forward, either in similar crises or as the world continues to move towards greater digital communication and connectedness. © 2022 The Authors, IDS Bulletin © Institute of Development Studies and Crown Copyright 2022
