Hydraulic Traffic Reduction Mechanism
Abstract: AbstractUrbanization and the surge in vehicle ownership have led to escalating traffic congestion, particularlyin densely populated metropolitan regions. Conventional traffic management systems, which depend onfixed lane structures and pre-set signal timings, often struggle to accommodate the increasing andunpredictable nature of traffic flow. This challenge necessitates the development of adaptive andintelligent traffic management solutions that can dynamically adjust to real-time conditions. A novelapproach to mitigating traffic congestion is the Hydraulic Traffic …

Mechanical and Microstructure Properties of Al and SiC Reinforced Aluminum-Based Metal Matrix Composite
Abstract: It is becoming increasingly difficult to design new technical materials that are resistant to wear damage and corrosion degradation in severe service circumstances. Unfortunately, even with crucial passive metals, like Al alloys, there is often a compromise between wear and corrosion resistance. Because of the unfavorable galvanic connection between the precipitates and the matrix, precipitates not only harden the material but also accelerate corrosion. This research established that a supersaturated …
