The brain's architecture is extremely intricate, with several regions controlling various nervous system processes. Any portion of the brain or skull can develop a brain tumor, including the brain's protective coating, the base of the skull, the brainstem, the sinuses, the nasal cavity, and many other places. Over the past ten years, numerous developments in the field of computer-aided brain tumor diagnosis have been made. Recently, instance segmentation has attracted a lot of interest in numerous computer vision applications. It seeks to assign various IDs to various scene objects, even if they are members of the same class. Typically, a two-stage pipeline is used to perform instance segmentation. This study shows brain cancer segmentation using YOLOv5. Yolo takes dataset as picture format and corresponding text file. You Only Look Once (YOLO) is a viral and widely used algorithm. YOLO is famous for its object recognition properties. You Only Look Once (YOLO) is a popular algorithm that has gone viral. YOLO is well known for its ability to identify objects. YOLO V2, V3, V4, and V5 are some of the YOLO latest versions that experts have published in recent years. Early brain tumor detection is one of the most important jobs that neurologists and radiologists have. However, it can be difficult and error-prone to manually identify and segment brain tumors from Magnetic Resonance Imaging (MRI) data. For making an early diagnosis of the condition, an automated brain tumor detection system is necessary. The model of the research paper has three classes. They are respectively Meningioma, Pituitary, Glioma. The results show that, our model achieves competitive accuracy, in terms of runtime usage of M2 10 core GPU.

RMG is a very important industry for the Bangladeshi economy, but is criticized for long product supply times due to poor SCM. RMG requires obtaining real-time information and enhanced dynamic control, through utilizing information sharing and connecting stakeholders in garment manufacture. However, a lack of IT support in the Bangladeshi RMG sector, the high price of computers and the low level of adoption of the computer based internet are obstacles to providing sophisticated computer aided SCM. Alternatively, explosive adoption of mobile phones and continuous improvement of this technology is an opportunity to provide mobile based SCM for the RMG sector. This research presents a mobile phone based SCM framework for the Bangladeshi RMG sector. The proposed framework shows that mobile phone based SCM can positively impact communication, information exchange, information retrieval and flow, coordination and management, which represent the main processes of effective SCM. However, to capitalize on these benefits, it is also important to discover the critical success factors and barriers to mobile SCM systems.

Whereas the United Nations (UN) and other development agencies concerned with climate impact, are advocating transformative actions towards smart cities, very little research in the IoT domain analyzes the advantages of IoT in achieving sustainable development goals (SDGs) to fill this gap. In this study, a smart office (SO) was developed in a Cisco packet tracer. We then presented the SO through the lens of SDGs. We suggest that SOs support targets mentioned in Goal 6, 7, 8, 9, 11 and 12 of the SDGs. This research is crucial-both for developing and developed economies, as we move toward industrialization, while ignoring the adverse impacts of industrialization. This work is expected to provide a pathway with technological innovation toward a more sustainable world for IT practitioners, governments and development agencies.

It ensures data integrity with authentic connected nodes. Now-a-days, blockchain with IoT is a great combination for secured and smart end to end product delivery. This observation has motivated the research to develop a conceptual model to provide a secure pharmaceutical product delivery by developing a IoT integrated with lightweight blockchain. The undeveloped and most of the developing countries are facing problems such as drug counterfeits, shortages, opiates and tracking them became difficult because of less transparency. Also, nature sensitive medicines need to be stored under controlled temperature known as cold-chain shipping. The storage of these information in the recent software is done in the centralized databases that is prone to data manipulations and hacks. Due to less production drugs needed to be imported with maintaining drug supply chain regulations by law. This paper proposes a lightweight blockchain model for pharmaceutical industries by using IoT. This model ensures traceability of drugs within a very simple way which is less complex compared to the existing ones.

However, the sector faces challenges in communication, worker disempowerment, and long lead times to produce finished goods. Research suggests that MbUS has potential development impact to improve communication, co‐ordination, and empowerment. This study narrows the gap through utilizing affordance theory as a theoretical lens to examine MbUS affordance applied to Bangladeshi RMGs. Using 39 interviews, this research explores five MbUS affordances ‐ connectivity, mobility, agility, empowerment and governance, and their relationship to Bangladeshi RMGs. Furthermore, we identify empowerment as a crucial affordance rarely identified in prior RMG literature. Our findings have potential value to RMGs, government, and mobile telecommunications.

Over the last ten years, a wide spectrum of m-banking frameworks has emerged that offers new insights into the adoption and acceptance of m-banking. However, m-banking has still not been extended to rural Bangladesh. To fill the gap this research surveyed 550 SMEs owners/managers in four rural villages. The result indicates that poor banking facilities, cost, credibility, gender, education and SME category are the main factors that significantly influence the intention to adopt m-banking. The analysis introduces three factors which have been largely overlooked in prior literature. The study broadens our understanding of m-banking and provides insights into developing m-banking strategies in Bangladesh. This research will be of potential value in accelerating the development of m-banking in Bangladesh.

Recently, scholars from developing countries have suggested that mobile phones have the potential to empower the deprived and disadvantaged. However, in the Bangladeshi context the topic is still under researched. This research fills a gap by presenting an initial mobile phone based empowerment framework for RMG workers. The framework examines possible mobile phone based empowerment tools that could provide workers with access to information, market and government. The framework suggests that outcomes include an increased sense of control, self-efficacy, knowledge and competency. In future, the empowerment framework presented in this research will be applied to the development of a mobile based information system for RMG workers. This research is significant as it adopts an empowerment focus rather than an individual consumer focused development outcomes. The outcomes and results of this research will be of potential value to the government, development agencies and mobile telecommunications in accelerating the development of mobile based services in Bangladesh and in other developing countries.7 page(s

Previous mobile phone-based studies have also advocated that mobile apps create a social network among the users. However, MCP studies have yet not addressed the notion of such social capital which is expected to contribute to the sustainable transportation in a city. MCP, in fact, can also create a communication network among car owners, drivers, and car park owners and offer a unique base for studying social capital and resource utilization opportunities. To reduce the gap in existing studies, in this study, an android-based MCP app was developed as a tool to study the components of social capital. After developing the MCP app, two focus group studies were conducted to explore the components an MCP app can provide. Lastly, we linked the social capital components to the sustainable transportation goals. This research pinpointed se...

This type of equipment is used to detect gas leakage or another emission. A gas warning device can alert operators in the vicinity of a possible gas leak and enable them to escape. The device is important because many gases can be harmful to organic life, such as humans or animals. This can be used to detect flammable, flammable, and toxic gases, as well as a lack of oxygen. Identifying potentially dangerous gas leaks through sensors. These sensors often use an audible alarm to alert people when dangerous gas has been detected. The purpose of this paper is to propose and discuss the design of an IoT-based gas leakage detection system that can automatically detect and warn gas leaks. The proposed system also includes a warning system for users. The system is based on sensors that can easily detect gas leaks.

Our study employed a qualitative research methodology based on interviews with RMG owners, workers, non-government organizations (NGOs) and IT experts. The interview data suggested MbIS has the potential to empower RMG owners/workers. MbIS-enabled empowerment suggests access to information, competency, impact; self-determination and meaning are empowerment components for RMG workers. Improved communication, the opportunity to access employee regulations, access to health and safety information, increased confidence with regard to ability and professional development opportunities are potential empowerment outcomes of using MbIS. This is one of the few papers examining MbIS comprehensively for worker empowerment, as most literature approaches the matter from the consumer standpoint, not in an organizational setting. The study contributes by providing practical knowledge to the RMG, government, and development organizationsin empowerment processes, components and empowerment outcomes using MbIS for RMG owners/employees. Other garmentproducing developing countries may also gain insight into how to empower RMG workers using MbIS.
