    A long-wave infra-red pulsed external-cavity QCL spectrometer using a hollow waveguide gas cell: Data
    (Cranfield University, 2024-04-25 08:45) Francis, Daniel; Hodgkinson, Jane; Tatam, Ralph
    A spectrometer built using an external cavity pulsed quantum cascade laser is described. The spectrometer has a tuning range from 10 €“ 13 um (1,000 €“ 769 cm-1) and is designed to target volatile organic compounds (VOCs) which often exhibit water-free molecular absorption within the region. The spectrometer utilizes a hollow silica waveguide gas cell which has an internal volume of a few millilitres, a fast response time (~1 s), and is advantageous when only low sample volumes, similar to the cell volume, are available.

    CogShift - Typical Trial
    (Cranfield University, 2023-12-11 15:47) Cecotti, Marco
    This is the video of one of the vehicle trials for the CogShift project. CogShift, one of five projects which are part of an £11 million UK Government investment in autonomous vehicle research, studied driver attention and cognitive control characteristics. The project developed an optimal control-authority shifting system which takes driver attention into account. More information can be found at https://www.cranfield.ac.uk/research-projects/cogshift.
