Digital Twins are new technology for improving asset performance. This video reviews creating digital twins for managing fuel economy for a fleet of trucks. Burning of fuel generates the emissions tracked by participants in the EPA Smart way program we used in the previous assignment. Monitoring and reporting on emissions generated by the assets owned by a company are classified as Scope $1$ reporting by the EPA. Please watch this video by Vnomics and post your answers to the following questions in a PDF file $(5$ points each$)$:

a$.$ Please explain what is a digital twin? $(5$ points$)$

$-$ A digital twin uses data from various sensors and devices attached to the asset. It also provides data from other sources such as weather reports, traffic patterns, and any relevant data as well. This data can be used to simulate behaviors and predict future performances.

b$.$ What are the $5$ determinants of trucking fuel economy? $(5$ points$)$

c$.$ Between the two tractor brands evaluated and reported on in this presentation, which brand performed best and by how much? $(5$ points$)$
