Rephasing of the intersection of city hall of Leiria

This project proposes two possible solutions for the phasing plan of the intersection near the City Hall of Leiria and presents the calculations of the cycle length and the intersection delay for both of them. The main goal of these solutions is to optimize the global functioning of the intersection. Since the number of cars that use an intersection is will fluctuate with time, when using pre-timed traffic lights, adjustments are needed to the settings of the traffic signals, to assure the accommodation of the present traffic flows in the intersection under acceptable conditions for drivers.

The role of additive manufacturing in patient specific solutions

This dissertation investigates de role of the new additive manufacturing techniques in the treatment of pathologies with a patient-specific approach. Throughout this work the development methodology of these said products is explained in order to understand the different stages required to achieve a tailor made solution. The goal is to demonstrate the importance of the manufacturing technique and its capabilities to tailor-fit devices to patients and the adaptability of the process to tackle the most diverse situations. Three real cases are documented in order to prove the viability of the method and to showcase its advantages. Whenever possible patient-specific solutions are compared to their “off-the-shelf” counterparts in order to establish the pros and cons of each one of them. The dissertation is an insight into a possible future for the medical devices industry, where customization is expected to be the standard approach in the treatment of patients.
