The research abstract explores the necessity of transitioning Zambia's domestic tax systems to a cloud-based failover architecture. Identifying existing challenges such as manual disaster recovery, system failures requiring human intervention, and inadequate logging, causing extended downtimes, data loss, and reduced taxpayer confidence. The study aims to introduce a hybrid cloud web application architecture, focusing on eradicating application downtime and ensuring taxpayer data security. Cloud-based standby failover architectures promise high uptime and data integrity, with servers hosted online to ensure uninterrupted business operations. The research objectives include creating a warm backup server on Amazon Web Services (AWS) private cloud servers, implementing data encryption policies, and evaluating the impact on tax application uptime and recovery metrics. The significance lies in enhancing system resilience, scalability, cost-efficiency, security, and accessibility, providing benefits like continuity, cost savings, security enhancements, and technological advancements. The methodology involved expert consultations and historical analysis to identify system inefficiencies, determine efficient failover architecture, and gather relevant literature for a secure hybrid cloud approach. The prototype test environment was successfully set up and tests were conducted, requiring scaling to mirror the ZRA production environment. Tasks including data encryption and security checks on application databases were implemented. Results support the hypothesis that the advantages of a cloud-based failover system outweigh potential challenges like data security, sovereignty concerns, cost management, integration complexity, legal compliance, and cybersecurity threats.

This paper explores the significance of interoperabil-ity advancements in learning management systems (LMS) and the demand for customizable, flexible learning environments. We present a system that integrates learning resources from an LMS into a highly customizable frontend, including the embedded TaskAssessment, a programming task evaluating software. By incorporating standards such as Learning Tools Interoperability (LTI) and Experience API (xAPI), seamless interoperability across various systems is ensured. The goal is to contribute to the advancement of personalized learning experiences by learning element recommendation, automatic assessment and targeted feedback, while improving system interoperability.

3D visual perception, including 3D object detection and map segmentation from multi-camera imagery, is pivotal for autonomous driving systems. In this study, we introduce a novel framework termed VFAST-BEV, which employs virtual cameras to transform the perspective views of real cameras into standardized camera views. Leveraging a fully convolution backbone network coupled with a Feature Pyramid Network (FPN), semantic segmentation is facilitated at higher layers, while at lower levels, an Inverse Perspective Mapping (IPM) and Multi-Layer Perception (MLP)-based spatial transformation module aggregates multiple front-view images into a unified Bird's Eye View (BEV) representation. This process implements BEV feature extraction based on Multi-layer Fusion (MLF), thereby achieving accurate 3D object detection, addressing the recognition errors that stem from traditional BEV learning methods relying on ideal assumptions about extrinsic parameters and an absolutely flat ground plane. Our approach not only supports a multitude of autonomous driving perception tasks but also reduces computational complexity by consolidating processing from six individual networks into a single one. Significantly, compared to transformer-based networks, the use of IPM and MLP has led to a tenfold decrease in computational demands. Experimental results demonstrate that the proposed BEV Virtual Camera methodology notably enhances the accuracy of target identification and object distance estimation under non-flat road conditions.
