SCALABLE SDN-BASED ARCHITECTURE FOR LARGE-SCALE ENTERPRISE NETWORK MANAGEMENT
Software-Defined Networking (SDN) has emerged as a transformative paradigm for enterprise network management, offering centralized control and programmability. However, existing SDN architectures face significant scalability challenges when deployed in large-scale enterprise environments with thousands of network devices and dynamic traffic patterns. This study proposes a novel hierarchical SDN architecture incorporating distributed controller clusters, dynamic load balancing, and optimized flow management mechanisms to address these limitations. We implemented and evaluated the proposed architecture using Mininet emulation with Fat-Tree topologies ranging from 16 to 128 hosts. Performance evaluation demonstrates that the proposed architecture achieves a 42% reduction in flow setup latency (5.2 ms vs. 8.5 ms), 18% improvement in throughput (850K vs. 720K flows/sec), and 65% reduction in packet loss compared to traditional single-controller SDN deployments. Statistical analysis using ANOVA confirmed significant performance improvements (p < 0.001) across all metrics. These findings establish that hierarchical SDN architectures with intelligent load balancing provide a viable solution for scalable enterprise network management, enabling organizations to leverage SDN benefits in production environments without compromising performance or reliability.

DEVELOPMENT OF ADAPTIVE THERMAL MANAGEMENT SYSTEMS FOR HIGH-PERFORMANCE ELECTRIC VEHICLES USING PHASE CHANGE MATERIALS
The growing demand for high-performance electric vehicles (EVs) necessitates advanced thermal management solutions to ensure optimal performance, safety, and longevity of critical components such as batteries and power electronics. This study investigates the development of adaptive thermal management systems (ATMS) for EVs using Phase Change Materials (PCMs). We explored the integration of various PCM materials, including paraffin wax, salt hydrates, and fatty acids, into thermal management systems, with a focus on enhancing thermal conductivity through the incorporation of nanomaterials such as carbon nanotubes (CNTs) and graphene. Our results demonstrate that PCM-based systems, particularly when enhanced with nanomaterials, exhibit significant improvements in thermal conductivity, energy efficiency, and temperature stability compared to conventional liquid cooling systems. Energy consumption was notably lower in PCM-based systems, especially under low and medium heat generation scenarios. However, the study also highlights challenges under high heat generation conditions, where PCM systems showed greater temperature fluctuations compared to liquid cooling systems. Long-term testing revealed a gradual decline in system efficiency over multiple cycles, although the PCM systems still maintained good temperature regulation performance. These findings suggest that PCM-based ATMS can provide a promising alternative to traditional cooling methods, offering lower energy consumption, better temperature stability, and the potential for extended system lifespan, particularly when integrated with adaptive control algorithms.

INVESTIGATING ADVANCED SEISMIC RETROFITTING TECHNIQUES FOR IMPROVING THE STRUCTURAL RESILIENCE OF EARTHQUAKE-PRONE BUILDINGS
This study investigates the efficacy of advanced seismic retrofitting techniques in enhancing the structural resilience of buildings located in earthquake-prone regions. The research evaluates the performance of various retrofitting systems, including seismic isolation, hybrid retrofitting, and shape memory alloy (SMA)-based systems, through a combination of experimental tests, microstructural analysis, and finite element simulations. The results demonstrate that seismic isolation systems provide the most significant improvement in structural performance, achieving the lowest peak displacement and maximum stress, thereby enhancing building stability during seismic events.

ADDRESSING CHALLENGES IN ENHANCING STRUCTURAL INTEGRITY AND PERFORMANCE THROUGH ADDITIVE MANUFACTURING OF METAL ALLOYS
This study investigates the influence of additive manufacturing (AM) process parameters on the structural integrity and mechanical performance of titanium and aluminum alloys. Using selective laser melting (SLM), specimens were produced under varying laser power and scanning speed conditions to assess their ultimate tensile strength (UTS), yield strength, fatigue resistance, and fracture toughness. The results revealed that higher laser power significantly improved the UTS of titanium alloys but led to a reduction in elongation, indicating a trade-off between strength and ductility. In contrast, the scanning speed had a more pronounced effect on aluminum alloys, where slower speeds resulted in stronger materials. The fatigue life of materials improved considerably after post-processing heat treatment while the aluminum alloys demonstrated specific advantages through enhanced cycle performances. The strength of fractures proved better following heat treatment as aluminum alloys demonstrated outstanding toughness improvements above raw specimens. The AM processing conditions allowed titanium alloys to produce fewer defects than aluminum alloys when analyzed via microstructural evaluations. The finite element analysis (FEA) predicted both temperature distributions and cooling rate patterns which validated against experimental results while demonstrating how cooling speed affects residual stresses as well as defect distribution during AM processing. Post-processing techniques and suitable processing parameters function as essential elements for enhancing both reliability and performance characteristics of AM metal alloys according to the study outcomes. The research presented viable insights for improving the quality of components from additive manufacturing which are particularly essential for aerospace and medical products. Research in the future should work on enhancing the optimization techniques and studying extended performance behavior of components manufactured using AM technology.
