Abstract: This research study proposes a unique method based on real-time environmental control for RRR planar serial redundant COBOT control, with the goal of improving safety and adaptability. Our work primarily focuses on the RRR planar manipulator, which allows for two-dimensional mobility thanks to its three revolute joints. The con-trol scheme monitors and analyzes the environment in real time by integrating sensors such as force/torque, proxim-ity, and vision systems. By using feedback, the manipulator's direction, velocity, and forces are dynamically changed in real-time in reaction to shifting environmental variables. The control method combines path planning, collision avoidance, and feedback control to produce instantaneous commands. This makes it possible to interact with items and avoid barriers in a safe and effective manner. By reduc-ing the likelihood of mishaps and enabling efficient operation in fluid, unstructured environments, this tactic im-proves versatility, productivity, and safety. The research has the potential to significantly enhance intelligent and self-governing adaptation in numerous fields, including manufacturing, assembly, and cooperative robotics. As sensing technologies, control algorithms, and com-puter capabilities advance, so does the possibility for real-time environmental-based control strategies for RRR planar manipulators in the context of current industrial automation. It appropriately responds to reviewer criticism and lays the foundation for the development of more capable and effective robotic systems under complex and dynamic conditions.

Abstract: Image classification is a fundamental task in computer vision that has seen tremendous advances with the advent of deep learning. In the medical imaging domain, image classification using deep neural networks has shown potential for automated analysis and diagnosis. In this work, we investigate convolutional neural networks (CNNs) for brain tumor image classification using magnetic resonance imaging (MRI) scans. The accurate classification of brain tumors from MRI scans enables non-invasive screening and diagnosis, thus improving clinical workflows and patient outcomes. We provide a review of CNN architectures for image classification, and discuss relevant datasets for brain tumor MRI analysis. We identify limitations of prior arts and propose a methodology leveraging CNNs for enhanced multi-class brain tumor classification performance. Our contributions include comparative evaluations of CNN architec-tures, optimization techniques, and preprocessing strategies. Extensive experiments demonstrate that our proposed approach achieves state-of-the-art classification accuracy on benchmark datasets. We employ data augmentation, batch normalization, and dropout regularization to prevent overfitting and improve generalization. The ReLU activation and Adam optimization enable efficient training. Qual-itative and quantitative results validate the efficacy of our methodology, while ablation studies provide insights into model components. We conclude by summarizing our findings, and discussing potential extensions as well as limi-tations of our approach to guide future works. Our work aims to advance research on employing deep CNNs for computer-aided diagnosis using MRI scans.

Abstract: The issue of learning poverty, which signifies the inability of students to attain essential literacy and numeracy skills, has gained significant prominence in the global education landscape. This research undertakes a comprehensive examination of learning poverty as a crucial facet of quality education, with a specific focus on the primary school system in Rwanda. Through a thorough analysis encompassing historical perspectives, current realities, and prospective trajectories that have materialized with the pursuit of education for all, this study endeavors to shed light on the intricate elements that contribute to the prevalence of learning poverty in Rwandan primary schools. By critically assessing the effectiveness of existing educational practices and interventions, this research seeks to untangle the multifaceted factors that underlie the manifestation of learning poverty in this context. The analysis reveals that the notable increase in primary school enrollment over the past 15 years has not only raised concerns about the quality of education but has also resulted in the emergence of learning poverty as a consequential outcome. This study finds that learning poverty is primarily attributed to the discrepancy between the growing enrollment and the limited availability of learning infrastructure, tools, materials, and qualified teaching staff. Therefore, it is suggested to establish a transformative education strategy that revolves around early, strategic, and inclusive investments, prioritizing foundational skills and quality outcomes.

Article: “A Cathedral of doom”: Oral tradition and prophecy in Kofi Awoonor’s “The Cathedral” and Kofi Anyidoho’s “The Kingmaker”
Josephine Delali Ofei
Vol 6, Issue 8; August 2023
North American Academic Research, 6(8) 10-19 August 2023, https://doi.org/10.5281/zenodo.8300133
Abstract: Oral tradition, which assembles knowledge, memories, and values have been typically configured in the linguistic artifacts of a nonliterary or aesthetic-literary nature. This is by far reflected in the works of most African literary writers who reappropriate the colonial heritage and language to be the foundation upon which they build their innovation, activism, and the general education of their African brethren. The works of Kofi Awoonor and Kofi Anyidoho fall within this categorization. Some of their works depict them as disquieted individuals advocating for the sustenance of the African tradition. The issues they contend with revolve around those who were encroaching on their territory and oppressing their culture. This they do by immersing their works in their Ghanaian Ewe heritage. It is against this backdrop that the current study attempts to examine Kofi Awoonor’s “The Cathedral”. It stresses the poem as a prophecy to the president, Akuffo-Addo’s pledge to build a national cathedral in Ghana. The study establishes the poem as a part of the blame culture that many Africans have used to explain the situation on the continent. To support the analysis of this poem is Kofi Anyidoho’s “The Kingmaker” which provides a caution to the problem generated by a foreign invasion in the African continent. The study launches the place of the two poems as an immense contribution to modern African poetry by relying on the concept of orality to undertake a content anal-ysis of the two poems. It identifies that the two poems kindle a nationalistic feeling in Africans at large.
