    A Price Based Spectrum Sharing Scheme in Wireless Cellular Networks
    (IIST, 2013-11-08) Kalolo, Sadath; Sam, Anael; Machuve, Dina; Anatory, Justinian
    Radio frequency spectrum scarcity has become a high priority research area over the past few years. The huge increase of network subscribers with multimedia applications coupled with underutilization of radio frequency spectrum motivates the search for other measures to address the scarcity of radio frequency spectrum. This work investigates on a price based spectrum sharing scheme for connection-oriented traffic in wireless cellular networks as a solution to address the scarcity of radio frequency spectrum. Dynamic pricing approach is applied with traffic overflows into neighbor networks. Performance evaluations of the scheme at steady state using MATLAB simulations reveal significant gains to the quality of service. Application of the scheme to highly loaded network traffic improves both network revenue and traffic channel utilizations.

    An Overview of Maternity healthcare Monitoring in Developing Nations
    (Tanzania Journal of Engineering and Technology, 2024) Kyambille, Godphrey G.; Mvuma, Aloys N.; Machuve, Dina
    A healthcare monitoring arrangement is essential for frequently monitoring a patient's health status. Specifically, maternal healthcare systems for tracking are utilized to evaluate the clinical status and monitor any abnormal condition changes during all three trimesters. This paper's objective is to conduct an extensive literature review and acknowledge earlier initiatives and studies conducted previously in maternal health care monitoring. This review focuses on accumulating information from earlier work and presents a general overview of previous studies concerning maternal health care monitoring (MHCM). The paper focuses on the maternal healthcare systems in developing countries accessed by pregnant women during the antenatal period. Furthermore, this paper highlights the challenges in the maternal health sector that include inadequate work conditions for health workers, home-based birth practices, long distances to healthcare facilities, and long waiting times in health facilities. The paper indicates the potential opportunities to strengthen maternal healthcare services and allow effective access to maternal healthcare facilities by pregnant women

    Common Beans Imagery Dataset for Early Detection of Bean Rust and Bean Anthracnose Diseases
    (Elsevier, 2024) Laizer, Hudson; Mduma, Neema; Machuve, Dina; Maganga, Reinfrid
    Common bean plays a crucial role in the agricultural sector in Tanzania. To most smallholder farmers, the crop serves as a principal source of protein and an essential source of in come. Despite its significance, common bean production is often affected by diseases, particularly bean rust and bean anthracnose, resulting in low yields and diminished eco nomic returns. To address this challenge, a comprehensive dataset of common bean leaf images has been collected by using smartphone cameras to capture the visual character istics of healthy and diseased leaves. The dataset contains more than 59,072 labeled images, offering a valuable re source for developing machine learning models and user friendly tools capable of early detection and diagnosis of bean rust and bean anthracnose diseases. The aim of gen erating this dataset is to facilitate the development of ma chine learning tools that will empower agricultural extension officers, smallholder farmers, and other stakeholders in agri culture to promptly identify and diagnose affected crops, en abling timely and effective interventions before causing sig nificant economic loss. By equipping farmers with the knowledge and tools to combat these diseases, we can safeguard bean production, enhance food security, and strengthen the economic well-being of smallholder farmers in Tanzania and other parts of Africa.

    Women's Satisfaction on Maternal Healthcare Services in Public Health Facilities: A Case of Meta Maternity Hospital
    (Tanzania Medical Journal, 2025-05-01) Kyambille, Godphrey; Mvuma, Aloys; Machuve, Dina; Rugumisa, Bernadether; Mang'ara, JL. Revocatus
    Satisfaction with healthcare services serves as a key measure of quality in healthcare systems. Although the Ministry of Health in Tanzania has introduced attentive and respectful health service, the satisfaction levels among pregnant women with delivery services at public hospitals remain inadequately addressed.
