  1. 6. Ultra-wideband People Counter

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Murali Tejeshwar Janaswami; [2022]
    Keywords : ;

    Abstract : People counters built using wireless technologies(for example, Wi-Fi or Bluetooth) can better estimate the people count if they can detect and handle false trajectories of people. One way to detect false trajectories is to continuously measure how far a person is from the people counter. READ MORE

  3. 7. Development Of Lung Phantoms for Detection Of Acute Respiratory Distress Syndrome

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Wassim Wahbeh; Youssef Hasan; [2022]
    Keywords : DARDS;

    Abstract : The goal of this project was to fabricate a deflated and an inflated phantom to replicate how the human lung tissues’ permittivity changes under a pathological condition for instance acute respiratory distress syndrome (ARDS). Furthermore, the lung phantom should be shaped like real human lungs. READ MORE

  4. 8. A Study of Multipath Propagation and Doppler Effect at 24GHz ISM band

    University essay from Högskolan i Gävle/Elektronik

    Author : Shaikh Masud Rana; [2020]
    Keywords : Multipath Propagation; Doppler Effect; 24GHz; ISM Band;

    Abstract : The wideband channel has been analyzed at the University of Gävle by using millimeter-wave (mm-Wave) frequency for improving the fifth-generation (5G) in Radio-frequency (RF) characterization. The proposed mm-Wave frequency is 24GHz, which is carried out from measurement testbed at the Robotics Lab. READ MORE

  5. 9. An investigation on the possibility for bandwidth improvement of dielectric antennas via modification of their geometry

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

    Author : Nandan Dutta Chaudhury; [2020]
    Keywords : Multifunctional antenna array; AESA; Additive manufacturing; Stereolithography; Ultra-wideband antenna; Dielectric antenna; Embedded DRA; PSF; Multifunktionell antenngrupp; AESA; Additiv tillverkning; Stereolitografi; Ultrabredbandig antenn; Dielektrisk antenn; Inbäddad DRA; PSF;

    Abstract : The dielectric antenna is an interesting alternative to a metallic antenna. This is mainlydue to its low manufacturing cost and the possibility to fabricate complex antennageometry with the aid of additive manufacturing (AM). Sophisticated AM technologyprovides new degrees of freedom in shaping the outer and inner geometry of antennas. READ MORE

  6. 10. Clutter Removal in Single Radar Sensor Reflection Data via Digital Signal Processing

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Mohammadreza Kazemisaber; [2020]
    Keywords : Surveillance Radar; Ultra-Wideband Radar; Clutter Reduction; FMCW radar; Digital signal processing; Moving target detection; Doppler Processing.;

    Abstract : Due to recent improvements, robots are more applicable in factories and various production lines where smoke, fog, dust, and steam are inevitable. Despite their advantages, robots introduce new safety requirements when combined with humans. READ MORE
