  1. 21. Optimisation Of Ionospheric Scintillation Model Used In Radio Occultation

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Marta Boryczko; Tomasz Dziendziel; [2016]
    Nyckelord :Global Positioning System; ionospheric scintillation; optimization; Radio Occultation;

    Sammanfattning : This thesis is executed in cooperation with RUAG Space AB, which specializes in highly reliable on-board satellite equipment. The thesis focuses on the effect, which disturbs the amplitude and phase of a Global Positioning System (GPS) signal, called scintillation effect. It has a substantial impact on a GPS signal, during Radio Occultation (RO). LÄS MER

    Sammanfattning : This thesis explores the relationship between inhalation amplitude and turn-taking in spontaneous multiparty conversations held in Estonian. Respiratory activity is recorded with Respiratory Inductance Plethysmography. LÄS MER

  4. 23. Modal Analysis on a MIMO System : For an asphalt roller CC1200

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :You You; Daxin Chen; [2015]
    Nyckelord :Experimental modal testing; MIMO system; modal analysis; Matlab; numerical model; Reflex.;

    Sammanfattning : Impact hammer is the current modal testing way in Dynapac testing department. Due to highly damped characteristic of big construction machines, there are a few weaknesses for modal testing when using hammer, such as short response time, limited frequency resolution, poor quality of frequency response functions.

  5. 24. Polynomial trends of vegetation phenology in Sahelian to equatorial Africa using remotely sensed time series from 1983 to 2005

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Mozafar Veysipanah; [2014]
    Nyckelord :TIMESAT; remote sensing; GIMMS NDVI; Physical Geography and Ecosystem analysis; Sahel; phenology parameters; polynomial trends; vegetation; soil moisture; Earth and Environmental Sciences;

    Sammanfattning : Popular science Our understanding of global warming can be achieved in different ways. One way is to study the phenological parameters of vegetation. LÄS MER

  7. 25. Measurement of horses gaits using geo-sensors

    Master-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Xuefei Qin; [2014]
    Nyckelord :Horse’s gaits; Acceleration; Measurement; Sensors; Short Time Fourier Transform; Window functions; Least Squares; Classification.;

    Sammanfattning : The aim of this thesis is to determine the horse’s gait types using the acceleration values measured from the horse. A measurement was taken in Gävletravet, a total of five Nanotrak sensors were used, four on the different parts of the horse, and one on the hand of the horse’s driver, a car was driven parallel to the horse and the motions of the horse was recorded by a camera in order to synchronize with the data measured by the sensors, a total of four videos were recorded.
