  1. 26. Simulation of Precise Automatic Radio Frequency GroundStation Tracking For S-Band Satellites

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Akila Wajirakumara; [2021]
    Keywords : ;

    Abstract : Satellites are often known for possessing invariable motion causing its apparent position to drift in the sky from the perspective of a ground station. If these irregular drifts are not compensated, the performance of the communication link would be greatly affected. Hence, the satellite motion has to be tracked by the ground station antenna.

  3. 27. Adaptive Beam Management in 5G-NR: A Machine Learning Perspective

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Boqiang Wang; [2021]
    Keywords : Machine Learning; Neural Network; Beam Management; Beam Tracking; mmWaves; 5G NR; Beamforming; Technology and Engineering;

    Abstract : In this rapid era of technology, speed of communication has become an important factor. To overcome this challenge, 5G/NR technology is being explored. One of the ways of doing this is by using the so called millimeter wave spectrum. READ MORE

  4. 28. Audio-based Motion Detection

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Gopal Gomatam; Filip Dujmic; [2021]
    Keywords : sonar; motion detection; audio frequencies; audio processing; Technology and Engineering;

    Abstract : Motion detection is an essential technology and it has numerous use-cases, such as security tracking, automated door opening systems, and IP cameras. Commonly, passive infrared sensors or radio frequency sensors are used for motion detection. However, this thesis focuses on performing motion detection using existing hardware at audio frequencies.

  5. 29. Recurring perturbations limit the length of byproduct cross-feeding chains in digital communities

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Johanna Orsholm; [2021]
    Keywords : Byproduct; Cross-feeding; Digital evolution; Gut microbiome;

    Abstract : The human gut microbiome is important for health and development, and understanding its functioning and dynamics are of great medical importance. The microbiome food web is largely characterized by chains of byproduct cross-feeding (where metabolites of one organism are used as nutrients for another), yet a recent study have shown that the average length of the chains are considerably shorter than what metabolic capabilities of present species allow for.

  6. 30. 1D LIDAR Speed and Motion for the Internet-of-Things : For Railroad Classification Yards

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Edward Chancellor; Kasper Oikarinen; [2021]
    Keywords : LIDAR; Trains; Internet of Things; Motion-tracking; Rail transportation; Railroad classification yards.; LIDAR; Tåg; Sakernas internet; Rörelsespårning; Tågtrafik; Rangerbangårdar.;

    Abstract : This thesis is an investigation into the feasibility of one-dimensional Light Detection and Ranging (LIDAR) sensors for tracking the position and motion of trains on railroad classification yards. Carefully monitoring railway traffic in these areas is important, in order to avoid accidents, optimise logistical operations and hence reduce delays. READ MORE
