Empowering Wireless Mesh Uav Networks Through Software-Defined Networking, Hieu Quang

Electrical and Computer Engineering ETDs

Unmanned Aerial Vehicles (UAVs) have been widely deployed in applications such as environmental monitoring, disaster response, and surveillance. Effective coordination between UAVs depends on low-latency inter-UAV communication to exchange state information, decisions, and other critical data. UAV networks are inherently dynamic which necessitates a framework capable of handling scenarios such as traffic re-routing, and resilience to communication failures. To address the challenges of managing dynamic UAV networks, this thesis proposes a dual network approach composed of three main components. First, the Better Approach to Mobile Ad-hoc Networking (BATMAN) protocol is used to enable communication among UAVs. Second, the OpenFlow protocol …

Space Vectors Discretization-Based Direct Torque Control Scheme For High Performance Induction Motor Drives, Francisco Balenga, Francis Mwasilu

Tanzania Journal of Engineering and Technology (TJET)

In this paper, a direct torque controller (DTC) based on discretization of space vectors (DSV-DTC) for induction motor drives is proposed. By using this technique, the number of voltage vectors is increased, consequently it reduces the torque ripple compared to the conventional DTC control scheme. Specifically, the switching table of the proposed DSV-DTC scheme is comprised of thirty-six nonzero voltage vectors compared to the six voltage vectors in the conventional DTC scheme. Furthermore, it makes use of a five – level torque hysteresis comparator instead of three-level of the conventional DTC. The performance of the proposed control scheme is validated …

Dynamic-Based Assessment Of Shear Connectors In Composite Bridges With Data Taken From The Surface Of The Deck Slab, Emmanuel S. Leo

Tanzania Journal of Engineering and Technology (TJET)

Most bridge management systems generally rely on visual inspections for condition assessment; this means that damage in inaccessible parts of the structure, such as shear connectors in concrete composite bridges, can remain undetected until failure occurs. Localised non-destructive techniques are limited to small areas, time-consuming, and require prior knowledge of the damaged zone. These limitations can be overcome by using dynamic-based techniques. This study aims to investigate experimentally the efficiency of dynamic-based techniques in assessing the condition of shear connectors based on measurements taken from the surface of the deck slab. The study involved the construction of five composite beam …
