Development of a whole life cycle cost model for electrification options on the UK rail system

Projects to deliver Overhead Line Equipment (OLE) electrification on the UK rail infrastructure system presents technical challenges which the rail industry in Britain have not traditionally had to consider. Whole Life Cycle assessment provides decision makers with cost estimates for the installation phase and over the entire service life of the system, including disposal. The OLE projects face a particular problem when analysing the best option for overbridges. Much of the rail infrastructure has not traditionally had to consider overhead clearances and therefore many of the bridges are only a little taller than the rolling stock. In addition to the difficulties in assessing the Life-Cycle costs of assets that have historically been used in very limited scales, the Whole Life Cycle assessment must consider the various engineering options that are available for projects. The three competing options (bridge rebuild, track lowering, reduced clearance) are all going to have very different capital expenditure (CAPEX) and operating expenditure (OPEX) costs. This work presents a model created to predict these costs over the anticipated assessment period. The developed model predicts capital expenditures, maintenance and service disruption costs and links them to the three major assets options involved in OLE underbridges

Un nuovo ponte per Stadano Bonaparte

La presente tesi di laurea ha come obiettivo lo studio di una soluzione progettuale per il nuovo ponte sul fiume Magra a Stadano nel comune di Aulla. Tra le verie ipotesi progettuali è stata scelta quella di un ponte ad arco a spinta eliminata, formato da due archi tubolari gemelli riuniti in mezzeria, di luce complessiva pari a 122 metri circa

Le Assicurazioni e i Fondi Pensione nel contesto operativo delle Cooperative Sociali: il caso della Cooperativa Sociale Paim

Questo mio elaborato che vado a proporre si pone come obiettivo quello di descrivere e raccontare il mondo, sconosciuto ai più, delle Cooperative Sociali, evidenziando alcune peculiarità del loro funzionamento. In particolare mi soffermerò sull'analisi della Cooperativa Sociale Paim, importante realtà del nostro territorio, nella quale sono fiera di lavorare

A Comparative Study of Machine Learning Models for Tabular Data Through Challenge of Monitoring Parkinson's Disease Progression Using Voice Recordings

People with Parkinson's disease must be regularly monitored by their physician to observe how the disease is progressing and potentially adjust treatment plans to mitigate the symptoms. Monitoring the progression of the disease through a voice recording captured by the patient at their own home can make the process faster and less stressful. Using a dataset of voice recordings of 42 people with early-stage Parkinson's disease over a time span of 6 months, we applied multiple machine learning techniques to find a correlation between the voice recording and the patient's motor UPDRS score. We approached this problem using a multitude of both regression and classification techniques. Much of this paper is dedicated to mapping the voice data to motor UPDRS scores using regression techniques in order to obtain a more precise value for unknown instances. Through this comparative study of variant machine learning methods, we realized some old machine learning methods like trees outperform cutting edge deep learning models on numerous tabular datasets.Comment: Accepted at "HIMS'20 - The 6th Int'l Conf on Health Informatics and Medical Systems"; https://americancse.org/events/csce2020/conferences/hims2
