  1. 11. A study of methods to synchronize different sensors between two smartphones

    University essay from KTH/Hälsoinformatik och logistik

    Author : John Abdulnoor; Ramy Gawriyeh; [2021]
    Keywords : Sensors; android; smartphones; synchronization; internal clocks; Cristian’s algorithm; Marzullo’s algorithm; round-trip time; Wi-Fi Direct; Sensorer; android; smartphones; synkronisering; interna klockor; Cristians algoritm; Marzullos algoritm; round-trip time; Wi-Fi Direct;

    Abstract : Obtaining data simultaneously from different sensors located on different mobile devices can be useful for applications such as sports and medicine. In order for the data from the different sensors to be combined for analysis, the mobile devices need to be time synchronized first. READ MORE

  3. 12. Galaxies as Clocks and the Universal Expansion

    University essay from KTH/Fysik

    Author : Anders Ahlström Kjerrgren; [2021]
    Keywords : cosmology; cosmic chronometers; universal expansion; Hubble parameter; differential ages; galaxy age; relative age; cosmic time; chi-square minimization; monte carlo sampling; gaussian processes; kosmologi; kosmisk kronometer; universums expansion; Hubbleparametern; differentiell ålder; galaxålder; relativ ålder; kosmisk tid; chi-2-minimering; monte carlo-sampling; gaussiska processer;

    Abstract : The Hubble parameter H(z) is a measure of the expansion rate of the universe at redshift z. One method to determine it relies on inferring the slope of the redshift with respect to cosmic time, where galaxy ages can be used as a proxy for the latter. This method is used by Simon et al.

  4. 13. Energy and Circadian Assessment of a Combination Between Integrative Lighting and Daylight Harvesting

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Author : Ribhi Attar; Omar Al Mawla; [2021]
    Keywords : ALFA; Circadian Entrainment; Correlated Colour Temperature; Cortisol; Daylighting; Daylight Harvesting; Energy efficiency; Integrative lighting; Intrinsically photosensitive retinal ganglion cells; Melatonin; Melanopic Lux; Photopic Lux; Spectral Power Distribution; Technology and Engineering;

    Abstract : This study deals with the health and wellbeing of humans who work in offices as well as the energy use for the lighting. The focus is on how integrative lighting and daylight harvesting can be combined in an attempt to reduce the energy consumption while still eliciting a circadian response for the workers. READ MORE

  5. 14. Testing universal Compton clocks using clock interferometry

    University essay from KTH/Fysik

    Author : Thomas Agrenius Gustafsson; [2020]
    Keywords : ;

    Abstract : .... READ MORE

  6. 15. Time Synchronization of TDOA Sensors Using a Local Reference Signal

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Alfred Hult; [2020]
    Keywords : TDOA; synchronization; sensor network; correlation; time-delay estimation; estimation; UAV; GPS; timing signal;

    Abstract : Synchronization of distributed time difference of arrival (TDOA) sensor networks can be performed using reference signals from GPS satellites. This method provides high accuracy, but is vulnerable to jamming, and is not reliable enough to be used in military applications. READ MORE
