We aim to evaluate whether the first National Emergency Medical Service (NEMS) improved access to hospital care for the people of Sierra Leone. We performed an interrupted time-series analysis to assess the effects of NEMS implementation on hospital admissions in 25 facilities. The analysis was also replicated separately for the area of Freetown and the rest of the country. The study population was stratified by the main Free Health Care Initiative (FHCI) categories of pregnant women, children under 5 years of age, and populations excluded from the FHCI. Finally, we calculated direct costs of the service. We report a 43% overall increase in hospital admissions immediately after NEMS inception (RR 1.43; 95% CI 1.2–1.61). Analyses stratified by FHCI categories showed a significant increase among pregnant women (RR 1.54; 95% CI 1.33–1.77) and among individuals excluded from the FHCI (RR 2.95; 95% CI 2.47–3.53). The observed effect was mainly due to the impact of NEMS on the rural distr...

The thesis addresses the issue of monocular relative pose determination for non-cooperative spacecrafts. An algorithm, called SVD method, is described and its peculiarities are discussed. The SVD technique is implemented both on a dataset of synthetic imagery of PRISMA mission's Tango spacecraft and on a dataset of real images of a CubeSat mock-up. The results are, then, analyzed so to highlight the fundamental limitations and the optimal operative range for the SVD architecture.
